Abstract

The purpose of the study is to examine the effect of perceived supervisor support on the relationship between ethical leadership and employee engagement through organisational commitment in eastern culture. The study uses survey data from 389 employees of information technology sector in Pakistan. To study the relationship between the variables, linear regression, and Preacher & Hayes () PROCESS techniques are used. The results of the study show that ethical leadership relates to employee engagement and organisational commitment. Organisational commitment mediates the relationship between ethical leadership and employee engagement. Perceived supervisor support moderates the relationship such that when perceived supervisor support is high, the effect of ethical leadership on employee engagement through organisational commitment is stronger. The results show that the positive perception of the supervisor complements the effect of ethical leadership on employee engagement through organisational commitment. Ethical leadership contributes towards the development and sustenance of organisational commitment and engagement among the employees. Drawing on social exchange theory, this study contributes to the organisational behaviour literature by studying the complementing effect of perceived supervisor support on the relationship between ethical leadership and employee engagement. An area that needs due attention.

Abstract

Anomalous waves propagation is severely affected due to almost always present variations in refractivity under various environmental conditions at different time, location and frequency. These conditions, representing different state of the atmosphere including e.g. foggy, rainy and cloudy etc., not only degrade the quality of the signal but sometimes completely eradicate the communication link. Such severe impact on propagation cannot be ignored by the designers of communication systems. The aim of this research is to present correlation between experimental and modelled link losses for variations in refractivity values recommended by International Telecommunication Union-Recommendations (ITU-R) as well as that of standard profiles. To do so, a communication setup of 50 km over the Sea operating experimentally over a period of a year at 240 MHz is analyzed for different refractivity profiles and their impact on propagation. A median value is taken for every set of 6000 values taken from the recorded data set of more than 48 million experimental link losses. This reduces the huge data set of the experimental link losses to 8000 values only. This reduced data set of experimental and modelled link losses were correlated and investigated for different evaporation duct heights throughout the year. For the considered link, the ITU-R refractivity profile was found to perform better than the standard refractivity profile. However, the new findings as observed in this research, which may be helpful for the recommendations authorities, is the existing of evaporation duct up to 10 m height.

Abstract

This paper investigates the impact of tube wells on the discharge and water table of the Quetta Valley aquifer and conducts a financial analysis of the solar photovoltaic water pumping system (SPVWP) in comparison with a typical pumping system for the Water and Sanitation Agency of Quetta’s (WASA) tube wells. Quetta Valley is dependent on groundwater as surface resources are on decline and unpredictable. The population of this city has exponentially increased from 0.26 million in 1975 to 2.2 million in 2017 which has put a lot of pressure on the groundwater aquifer by installing more than 500 large capacity tube wells by WASA and Public Health Engineering (PHE) departments in addition to thousands of low-capacity private tube wells. The unprecedented running of these wells has resulted in drying of the historical Karez system, agricultural activities, and the sharp increase in power tariffs. There are 423 tube wells in operation installed by WASA in addition to PHE, Irrigation and Military Engineering Services (MES), which covers 60% of the city’s water demand. The results will be beneficial for organizations and positively impact the operation of these wells to meet public water demand. For the two zones, i.e., Zarghoon and Chiltan in Quetta Valley, recommendations are given for improved water management.

Abstract

This paper presents an optimization method for solving the Power Economic Dispatch (PED) problem of thermal generation units with multiple fuels and valve point loadings. The proposed optimizer is a variant of Differential Evolution (DE) characterized as a Stud Differential Evolution (SDE), which has been proposed earlier and implemented on a hydrothermal energy system. In SDE, an operator named Stud Crossover (SC) is introduced in the conventional DE during the trial vector updating process. In SC operator, a best vector gives its optimal information to all other population members through mating. The proposed algorithm’s effectiveness to solve Multiple Fuel PED problem, with and without Valve Point Loading Effects (VPLEs), has been validated by testing it on 10 machine multiple fuel standard test systems having 2400 MW, 2500 MW, 2600 MW, and 2700 MW load demands. The results depict the strength of SDE over various other methods in the literature.

Abstract

This paper presents line-interactive transformerless Uninterruptible Power Supply (UPS) with a fuel cell as the prime energy source. The proposed UPS consists of three major parts (i.e., an output inverter, a unidirectional DC–DC converter, and a battery charger/discharger). Non-isolated topologies of both the unidirectional converter and battery charger/discharger ensure transformerless operation of the UPS system. A new topology of high gain converter is employed for boosting the low voltage of the fuel cell to a higher DC link voltage, with minimum semiconductor count, and high efficiency. A high-gain battery charger/discharger realizes the bidirectional operation between the DC link and the battery bank. Besides, it regulates the DC link voltage during the cold start of fuel cells and keeps the battery bank voltage to only 24 V. A new inverter control scheme is introduced that regulates the output voltage and minimizes the total harmonic distortion for non-linear loading condition. The proposed control scheme integrates proportional-resonant control with slide mode control, which improves the controller’s performance in transient conditions. The proposed UPS system is validated by developing a 1-kVA experimental prototype.

Author

Muhammad Imran Munawar, Imtiaz Alam, and Muhammad Sharjeel Ali

Abstract

Prediction of Solar power generation plays an important role to improve the efficiency ofeconomic dispatch function and reduce the dependence on fossil fuels and help in the energy managementsystem. For time series solar energy prediction multiple models were introduced but these model trains arebased on yearly historical data. A big data collection containing many missing values makes these modeltraining more complicated that’s why In this paper, an efficient energy prediction model is proposed for theprediction of time series solar energy based on short predicted weather training data. Two complimentarymodels are based on linear regression and a knowledge based neural network is exploited to predict futuresolar power, with offline training. The LR is structured under the direction of the proposed input methodparameter selection and used when training data is enough. KBNN is used for existing advantagespredictive models are also very important when training data is not enough. According to test findings usingreal data sets. An LR model can deal effectively with linear data, but a KBNN model can cope effectivelywith nonlinear behavior. Additionally, the results demonstrate the effectiveness of LR showing a correlationcoefficient (R2) is 98% with a root mean square error of 45 and KBNN shows a correlation coefficient (R2)is 99% with a root mean square error of 44 in providing a reliable version, The results additionally showthe functionality of LR and KBNN in imparting a dependable version, especially when the short trainingdataset is available.

Author

Shaon Shahriar, Niloy Dipanker Ghosh, Shoeb Imtiaz Alam, Akhter Ahmed, and SM Quamrul Akther

Abstract

Periampullary neoplasms are a heterogeneous group of tumors arising within 2 cm of the ampulla of Vater. Neuroendocrine tumors can originate throughout the entire body from neuroendocrine cells. These neoplasms exhibit deep differences, according to their origin and biological behavior. The synchronous presence of a primary tumor in patients affected by a neuroendocrine tumor is reported in the literature; incidence is variable and the most common site is the gastrointestinal tract. Here we report a case of 68 years old female presented with jaundice, anorexia and weight loss. She was mildly anaemic. Gall bladder was palpable. There was no organomegaly. Her CT scan and MRCP revealed a growth in periampullary region. So she underwent Whipple’s procedure. Histopathological report showed synchronous presence of periampullary carcinoma and a carcinoid tumor in stomach. As the carcinoid tumor was nonfunctioning and very small in size, it was not identified in pre-operative work up. J Shaheed Suhrawardy Med Coll 2021; 13(2): 183-186

Abstract

Background: Evidence-based decision-making is essential to improve public health benefits and resources, especially in low- and middle-income countries (LMICs), but the mechanisms of its implementation remain less straightforward. The availability of high-quality, reliable, and sufficient data in LMICs can be challenging due to issues such as a lack of human resource capacity and weak digital infrastructure, among others. Health information systems (HISs) have been critical for aggregating and integrating health-related data from different sources to support evidence-based decision-making. Nutrition information systems (NISs), which are nutrition-focused HISs, collect and report on nutrition-related indicators to improve issues related to malnutrition and food security—and can assist in improving populations' nutritional statuses and the integration of nutrition programming into routine health services. Data visualization tools (DVTs) such as dashboards have been recommended to support evidence-based decision-making, leveraging data from HISs or NISs. The use of such DVTs to support decision-making has largely been unexplored within LMIC contexts. In Bangladesh, the Mukto dashboard was developed to display and visualize nutrition-related performance indicators at the national and subnational levels. However, despite this effort, the current use of nutrition data to guide priorities and decisions remains relatively nascent and underused. Objective: The goal of this study is to better understand how Bangladesh's NIS, including the Mukto dashboard, has been used and areas for improvement to facilitate its use for evidence-based decision-making toward ameliorating nutrition-related service delivery and the health status of communities in Bangladesh. Methods: Primary data collection was conducted through qualitative semistructured interviews with key policy-level stakeholders (n=24). Key informants were identified through purposive sampling and were asked questions about the experiences and challenges with the NIS and related nutrition dashboards. Results: Main themes such as trust, data usability, personal power, and data use for decision-making emerged from the data. Trust in both data collection and quality was lacking among many stakeholders. Poor data usability stemmed from unstandardized indicators, irregular data collection, and differences between rural and urban data. Insufficient personal power and staff training coupled with infrastructural challenges can negatively affect data at the input stage. While stakeholders understood and expressed the importance of evidence-based decision-making, ultimately, they noted that the data were not being used to their maximum potential. Conclusions: Leveraging DVTs can improve the use of data for evidence-based decision-making, but decision makers must trust that the data are believable, credible, timely, and responsive. The results support the significance of a tailored data ecosystem, which has not reached its full potential in Bangladesh. Recommendations to reach this potential include ensuring a clear intended user base and accountable stakeholders are present. Systems should also have the capacity to ensure data credibility and support ongoing personal power requirements. [ABSTRACT FROM AUTHOR]

Abstract

Background: Despite advances in surgery and pharmacotherapy, there remains significant residual ischemic risk after coronary artery bypass grafting surgery. Methods: In REDUCE-IT (Reduction of Cardiovascular Events With Icosapent Ethyl–Intervention Trial), a multicenter, placebo-controlled, double-blind trial, statin-treated patients with controlled low-density lipoprotein cholesterol and mild to moderate hypertriglyceridemia were randomized to 4 g daily of icosapent ethyl or placebo. They experienced a 25% reduction in risk of a primary efficacy end point (composite of cardiovascular death, myocardial infarction, stroke, coronary revascularization, or hospitalization for unstable angina) and a 26% reduction in risk of a key secondary efficacy end point (composite of cardiovascular death, myocardial infarction, or stroke) when compared with placebo. The current analysis reports on the subgroup of patients from the trial with a history of coronary artery bypass grafting. Results: Of the 8179 patients randomized in REDUCE-IT, a total of 1837 (22.5%) had a history of coronary artery bypass grafting, with 897 patients randomized to icosapent ethyl and 940 to placebo. Baseline characteristics were similar between treatment groups. Randomization to icosapent ethyl was associated with a significant reduction in the primary end point (hazard ratio [HR], 0.76 [95% CI, 0.63–0.92]; P =0.004), in the key secondary end point (HR, 0.69 [95% CI, 0.56–0.87]; P =0.001), and in total (first plus subsequent or recurrent) ischemic events (rate ratio, 0.64 [95% CI, 0.50–0.81]; P =0.0002) compared with placebo. This yielded an absolute risk reduction of 6.2% (95% CI, 2.3%–10.2%) in first events, with a number needed to treat of 16 (95% CI, 10–44) during a median follow-up time of 4.8 years. Safety findings were similar to the overall study: beyond an increased rate of atrial fibrillation/flutter requiring hospitalization for at least 24 hours (5.0% vs 3.1%; P =0.03) and a nonsignificant increase in bleeding, occurrences of adverse events were comparable between groups. Conclusions: In REDUCE-IT patients with a history of coronary artery bypass grafting, treatment with icosapent ethyl was associated with significant reductions in first and recurrent ischemic events.

Abstract

PurposeWith a foundation in social exchange theory, this study examines the relationship between servant leadership and three types of workplace mistreatment – bullying, incivility and ostracism – while also considering a mediating role of trust in the leader and a moderating role of the ethical climate.Design/methodology/approachThree time-lagged sets of data (N = 431) were collected among employees working in various sectors.FindingsServant leadership relates significantly to trust in the leader, as well as to workplace bullying, incivility and ostracism. In turn, trust in the leader mediates the relationship between servant leadership and all three types of workplace mistreatment. The results also indicate the presence of moderated mediation, in that the indirect effect of servant leadership on workplace mistreatment is moderated by the ethical climate.Originality/valueThis study adds to extant research by examining the mediating mechanism of trust in leaders with servant leadership and workplace mistreatment, along with interactive effects of ethical climate.

Abstract

In this study, the ballistic impact behavior of auxetic sandwich composite human body armor was analyzed using finite element analysis. The auxetic core of the armor was composed of discrete re-entrant unit cells. The sandwich armor structure consisted of a front panel of aluminum alloy (Al 7075-T6), UHMWPE (sandwich core), and a back facet of silicon carbide (SiC) bonded together with epoxy resin. Numerical simulations were run on Explicit Dynamics/Autodyne 3-D code. Various projectile velocities with the same boundary conditions were used to predict the auxetic armor response. These results were compared with those of conventional monolithic body armor. The results showed improved indentation resistance with the auxetic armor. Deformation in auxetic armor was observed greater for each of the cases when compared to the monolithic armor, due to higher energy absorption. The elastic energy dissipation results in the lower indentation in an auxetic armor. The armor can be used safely up to 400 m/s; being used at higher velocities significantly reduced the threat level. Conversely, the conventional monolithic modal does not allow the projectile to pass through at a velocity below 300 m/s; however, the back face becomes severely damaged at 200 m/s. At a velocity of 400 m/s, the front facet of auxetic armor was destroyed; however, the back facet was completely safe, while the monolithic panel did not withstand this velocity and was completely damaged. The results are encouraging in terms of resistance offered by the newly adopted auxetic armor compared to conventional monolithic armor.

Abstract

The agriculture sector is the most important, however, most vulnerable to climate change in Asia and the Pacific. Droughts are one of the leading sources of disaster risks that can alter yield levels and cause sizeable productivity losses in agricultural products. In response, the farmers are adopting several climate risk management strategies. Therefore, this study aims to find out farmers’ preferences for climate change adaptation strategies and their potential determinants. Data were collected from randomly selected 200 farmers in District Nowshehra, Khyber Pakhtunkhwa. A multivariate probit model was used to assess the impacts of various factors on farmers’ decisions to adopt a particular adaptation strategy. The findings of the study revealed that rainwater harvesting, change in the planting dates, soil conservation, ponds building, and terraces with spillways were the dominant adaptation strategies found to combat the ill effects of droughts in the study area. Furthermore, the study highlighted the potential role of socio-economic attributes in the adoption of these adaptation strategies. The findings suggested that the government may extend its support to these farmers in making ponds and providing them the storage of water facilities.

Abstract

Pilonidal sinus in the sacrococcygeal region is an acquired condition and usually seen in young male adults. Diagnosis is indicated by to see the site and appearance of chronic discharging opening, and identification of midline pit in the natal cleft. The management of the sacrococcygeal pilonidal sinus varies from clipping of hairs with good hygiene of the area, wide excision of the area with primary or secondary closure and newer flap procedures, but none is widely accepted. The main concern for the treatment to the patient is the recurrence. This prospective study has been performed to determine the effectiveness and safety of the Limberg flap procedure for sacrococcygeal pilonidal sinus for new and recurrent cases. Primary end point was rate of recurrence and secondary end points were its complianceand complications such as wound infection, postoperative pain and return to work. A total of 17 patients were operated from March 2012 to June 2016.Both primary and recurrent diseases were included. All patients successfully underwent surgery. Patients complained very minimal postoperative pain. LO were average 2 days. All patients were discharged with negative suction drain in situ. Drains were removed on 7th POD and stitches were removed on 9th to 12th postoperative day. All patients returned to work after 2nd weeks. In our study no recurrence or major complications were found. Limberg flap for sacrococcygeal pilonidal sinus was found very useful and effective in terms of recurrence rate and patients morbidity. J Shaheed Suhrawardy Med Coll, December 2020, Vol.12(1); 6-8

Abstract

Chronic pancreatitis is a fairly common condition with pain being the major symptom and longitudinal pancreaticojejunostomy (LPJ) is performed for symptomatic relief. The aim of the study is to assess the outcome of LPJ for chronic calcific pancreatitis and to evaluate the factors influencing relief of symptoms. A prospective observational study enrolling 28 patients was conducted in the department of surgery of Shaheed Suhrawardy Medical College Hospital from January 2018 to December 2018. This study involved identification of various risk factors related to chronic pancreatitis, pancreaticojejunostomy, early post-operative outcome and postoperative assessment of pain relief at 1 and 6 months from surgery. Pain was assessed using Visual analogue scale (VAS). In chronic pancreatitis, there is a significant relief of pain in post-LPJ; the degree of relief was less in the alcoholics than non-alcoholics (p=0.09) and in smokers. There was also reduction in analgesic requirement and frequency of acute attacks of pain. In chronic pancreatitis, there is a significant relief of pain in post-LPJ, although the degree of relief is less in the alcoholics and smokers.

Abstract

Background: Ulcers and surgical wounds not healing well and expectedly are common problems among patients in countries like us. Ulcers may develop spontaneously or following a penetrating injury. wounds not healing well are common among poor, lower middle class and middle class people. Postsurgical non-healing wound or chronic discharging sinuses at the scar site are also common in that class of people. Suspecting malignancy or tuberculosis in these types of wounds we have sent wedge or excision biopsy for these ulcers in about 500 cases and found tuberculosis in 65 cases. In rest of the cases histopathology reports found as non- specific ulcers, Malignant melanoma, squamous or basal cell carcinoma, Verruca vulgaris. Objectives: To find out the relationship of tuberculosis with chronic or nonhealing ulcers. Methods: This is a prospective observational study conducted for patients coming to our chambers, OPD of a district general hospital and Shaheed Suhrawardy Medical College Hospital, Dhaka from July 2012 to June 2018. Results: Mean age of the study subjects were 28±2. Among the study subjects nonspecific ulcer or sinus tracts were found in 418 (83.6%), tuberculosis in 65 (13%), Malignant melanoma 7 (1.4%), Verruca vulgaris 5(1%), squamous cell carcinoma 3(0.6), basal cell carcinoma 2 (0.4%). Biopsy done only for very suspicious ulcers or wounds. Conclusion: With this very small sample size it is difficult to conclude regarding incidence of cutaneous involvement of extra pulmonary tuberculosis , but every clinician should think of it in case of suspicious non healing wounds, ulcers and prolonged discharge from a surgical incision site.

Abstract

Intussusception is a relatively common etiology of abdominal pain in pediatric population. In adults, on the other hand, this entity is seen infrequently and a lead point can be recognized in a vast majority of cases. A 27 year old woman who was admitted in the Surgery Department of Shaheed Sohrawardy Medical College Hospital after experiencing severe upper abdominal pain associated with nausea, vomiting and fever. Later on the patient developed features of intestinal obstruction. Ultrasonography demonstrated small bowel intussusception. A jejunal intussusception 50 cm distal to the dudeno-jejunal junction was found during laparotomy. Resection and anasto mosis was performed as gut was not viable. A diagnosis of jejunal inflammatory fibroid polyp was made based on the histological findings which act as a lead point for jejunal intussusception.

Abstract

Haemophilia A is an X linked disorder characterized by bleeding manifestations due to deficiency of factor VIII. Administration of factor VIII is the mainstay of treatment in case of bleeding which is very costly. That’s why fresh frozen plasma is a very good alternative in the management of mild to moderate bleeding. Here we present a case of 50 years old male presented to us with traumatic scrotal haematoma who was newly diagnosed with Haemophilia A. As the patient was unable to bear the cost of factor VIII, we managed the patient by transfusing fresh frozen plasma. After raising his activity of factor VIII up to 30% which was adequate for soft tissue trauma, surgical exploration of scrotum was done. Both the testes were found viable. Evacuation of clot was done followed by secondary closure of the wound J Shaheed Suhrawardy Med Coll, December 2018, Vol.10(2); 118-121

Abstract

Background: Screening T2DM for NASH fibrosis using specific markers is mandatory, as liver enzymes are often normal despite advanced fibrosis. LIVERFASt (LF), a serum marker with CPT code for assessing liver fibrosis (LF-Fib), activity and steatosis had high performance for identifying severe NASH in T2DM. Aim: To demonstrate that LF-Fib is an alternative to biopsy (LB) for the estimation of the transition rate to fibrosis [F1 stage or more (TRF1)], in T2DM NAFLD with better performances than transient elastography (TE) and FIB4. Methods: TRF1 was evaluated using Cox-Mantel HazardRatios [HR(95%CI), logrank comparison] with a modeling of hazard from birth to age of LB, in prospectively collected NAFLD pts with concomitant LB and LF, TE, FIB4. Results: N=583pts were included, 52% T2DM, 56%males, median (range) age 59.5% (18-85), HbA1c 6.6% (4.7-12), BMI 31.5 (20-54)kg/m2 (obesity 59%). The estimation of TRF1 [HR(95%CI)] using LF-Fib was similar to that of LB in both T2DM [0.67 (0.56-0.80) vs. 0.65( 0.54-0.79)], and no-T2DM [1.50 (1.26-1.78) vs. 1.54 (1.27-1.86)], respectively, with earlier TRF1 in no-T2DM (logrank p Conclusion: Validated biomarkers such as LIVERFASt should allow a powerful analysis of fibrosis progression in T2DM similar to LB and better screening strategies for stratifying T2DM.

Abstract

Abstract Microcavities enable the generation of highly efficient microcombs, which find applications in various domains, such as high-precision metrology, sensing, and telecommunications. Such applications generally require precise control over the spectral features of the microcombs, such as free spectral range, spectral envelope, and bandwidth. Most existing methods for customizing microcomb still rely on manual exploration of a large parameter space, often lacking practicality and versatility. In this work, we propose a smart approach that employs genetic algorithms to autonomously optimize the parameters for generating and tailoring stable microcombs. Our scheme controls optical parametric oscillation in a microring resonator to achieve broadband microcombs spanning the entire telecommunication C-band. The high flexibility of our approach allows us to obtain complex microcomb spectral envelopes corresponding to various operation regimes, with the potential to be directly adapted to different microcavity geometries and materials. Our work provides a robust and effective solution for targeted soliton crystal and multi-soliton state generation, with future potential for next-generation telecommunication applications and artificial intelligence-assisted data processing.

Abstract

Nowadays, people are having a hectic schedule and hence sometimes unconsciously forget to turn off their gas burner in the kitchen. A significant amount of gas is being wasted. This system's fundamental goal is to develop a device for kitchen safety and reduce gas wastage, which concentrates on additional protection. This paper proposes an approach to automatically prevent any threat from the usage of the gas stove. This system is an ATmega328p microcontroller-based that deals with turning off the kitchen gas valve mechanism in various situations. It turns off the gas supply when it is not used for cooking purposes utilizing a solenoid valve. The gas burner will turn on when there must have a flame in the gas burner and a cooking pot on the gas burner. When smoke is detected, the temperature is high from its range, and there is any kind of unnecessary gas amount in the kitchen, then the exhaust fan will turn on automatically. Like a micro oven, there is also a timer system for cooking purposes at a particular time. Here also include a Bluetooth system for controlling the burner by voice. If there any gas leakage is detected, the system will make an alarm and inform the house owner by calling and sending a text. Also, there are various modes involved in this system. It highlights the provision for kitchen safety. It greatly assists in securing safety and making use of gas stove more convenient and easy.

Abstract

Confidentiality and authentication are primary concerns of RFID (Radio Frequency IDentification) based identification systems. Low cost, non sight-line scanning capability, unique identification and functional haste make RFID systems much more suitable for supply chain management and IoT networks, compare to barcodes and magnetic tapes. Since, RFID tags can be scanned from a greater distance over a radio channel which is easily accessible for adversaries, therefore numerous Ultralightweight Mutual Authentication Protocols (UMAPs) have been proposed to ensure the security of the RFID systems in a cost effective way. These UMAPs mainly involve low cost bitwise logical ( $$Triangular$$ ) operations such as $$XOR, AND OR$$ etc., usually these logical operations offer poor diffusion properties and hence result in disclosure of the concealed secrets. Almost all of the previous UMAPs have certain pitfalls and reported to be susceptible to Denial of Service, traceability, full disclosure and cloning attacks. In this paper, we propose a new UMAP that is resilient to structured and unstructured cryptanalysis techniques. The proposed Ultralightweight Resilient Mutual Authentication Protocol (URMAP) avoids all the pitfalls and unbalanced operators in its design that were the main reasons of failure of previous UMAPs. The incorporation of ultralightweight primitives; $$Per{\text{-}}XOR$$ ( $${P}_{x})$$ and $$Inverse Per{\text{-}}XOR$$ $$({ P}_{x}^{-1})$$ makes the protocol messages more resistant to all types of adversaries. The security and privacy capabilities of URMAP are evaluated through formal analysis. The results of GNY Logic analysis prove that the proposed protocol is resilient to all possible attack scenarios thus ensuring optimal confidentiality, integrity and availability services.

Abstract

Anomalous waves propagation is severely affected due to almost always present variations in refractivity under various environmental conditions at different time, location and frequency. These conditions, representing different state of the atmosphere including e.g. foggy, rainy and cloudy etc., not only degrade the quality of the signal but sometimes completely eradicate the communication link. Such severe impact on propagation cannot be ignored by the designers of communication systems. The aim of this research is to present correlation between experimental and modelled link losses for variations in refractivity values recommended by International Telecommunication Union-Recommendations (ITU-R) as well as that of standard profiles. To do so, a communication setup of 50 km over the Sea operating experimentally over a period of a year at 240 MHz is analyzed for different refractivity profiles and their impact on propagation. A median value is taken for every set of 6000 values taken from the recorded data set of more than 48 million experimental link losses. This reduces the huge data set of the experimental link losses to 8000 values only. This reduced data set of experimental and modelled link losses were correlated and investigated for different evaporation duct heights throughout the year. For the considered link, the ITU-R refractivity profile was found to perform better than the standard refractivity profile. However, the new findings as observed in this research, which may be helpful for the recommendations authorities, is the existing of evaporation duct up to 10 m height.

Abstract

Paget’s disease of the breast is a rare type of cancer of the nipple–areola complex and that is often associated with an underlying in situ or invasive carcinoma. It is often misdiagnosed as eczema of breast and treatment is delayed. Here we present a case where a 30 year old female presented with itching ulceration and destruction of her left nipple. She was treated initially by local physicians by applying local ointments but as her condition did not improve she was admitted to department of surgery Shaheed Suhrawardy Medical College hospital where she was diagnosed as Paget’s disease with infiltrating ductal cell carcinoma. She underwent modified radical mastectomy with axillary clearance and referred to oncology department for further management. J Shaheed Suhrawardy Med Coll, June 2019, Vol.11(1); 81-83

Abstract

The value of thrombolysis by Streptokinase administration in the treatment of acute myocardial infarction is well established. Haemorrhage is a common complication of fibrinolytic therapy. Here, we report an unusual case of spontaneous lingual and sublingual haematoma following streptokinase therapy after acute myocardial infarction. A 57-year-old man with a diagnosis of acute ST elevated myocardial infarction treated with streptokinase developed a large lingual and sublingual haematoma. Though his airway was not compromised, he had difficulty in swallowing. A conservative approach was made by starting parenteral nutrition, preventing rethrombosis by not reversing the action of streptokinase as his coagulation profile was within normal limits and maintaining optimum blood pressure, blood glucose level and urine output. His tongue swelling subsided after four days and oral medication and feeding was started. No complication occurred during this period. Though there is no adequate information regarding the management of the patient, a vigilant monitoring of the patency of the airway with a conservative approach by not reversing the effect of streptokinase and preventing coronary rethrombosis may produce a better outcome in such cases.Cardiovasc. j. 2017; 10(1): 97-100

Abstract

In recent years, utilization of power electronic converters has been drastically increased. These converters act like non-linear loads for utility grid. Such non-linear loads distort the supply current through injection of harmonics. One such example is the uninterruptible power supply (UPS) system, which is a major source of current harmonics. These harmonics affect the performance of distribution transformers in terms of losses, heating of core, stress on insulation and tripping of the protection relays. In this paper, the increase of total harmonic distortion (THD) of the supply current, caused by uncontrolled rectifiers used in UPS systems, has been minimized. Two methods including passive filters (PF) and active filters (AF) have been applied to minimize the THD. The simulations have been performed in MATLAB/Simulink environment where the results of both schemes have been compared under various load conditions (RL and unbalanced load). It has been found that AF provides a better solution as compared to PF for such load conditions.

Abstract

The objective of this study is to give a clear overview of the insurance companies operated in the Bangladesh. This study aims to find the determinants of the underwriting risk of the insurance companies in Bangladesh. Further it extends the study to determine the decision and risk taking ability of the insurance companies in the Bangladeshi context. The sample used in this study has taken from the Bangladeshi insurance company incorporated under the Bangladeshi insurance act for the time frame between 2013 and 2017. Using SPSS statistical software the multiple linear regression analysis has been done. Empirical result shows that underwriting risk is related to the different factors such as firm size, capital level, GDP, liquid asset and return on asset. The limitation of this study was the lack of availability of the data and sample is limited to Bangladeshi insurance company.
