Abstract The essence of quantum machine learning is to optimize problem-solving by executing machine learning algorithms on quantum computers and exploiting potent laws such as superposition and entanglement. Support vector machine (SVM) is widely recognized as one of the most effective classification machine learning techniques currently available. Since, in conventional systems, the SVM kernel technique tends to sluggish down and even fail as datasets become increasingly complex or jumbled. To compare the execution time and accuracy of conventional SVM classification to that of quantum SVM classification, the appropriate quantum features for mapping need to be selected. As the dataset grows complex, the importance of selecting an appropriate feature map that outperforms or performs as well as the classification grows. This paper utilizes conventional SVM to select an optimal feature map and benchmark dataset for predicting air quality. Experimental evidence demonstrates that the precision of quantum SVM surpasses that of classical SVM for air quality assessment. Using quantum labs from IBM’s quantum computer cloud, conventional and quantum computing have been compared. When applied to the same dataset, the conventional SVM achieved an accuracy of 91% and 87% respectively, whereas the quantum SVM demonstrated an accuracy of 97% and 94% respectively for air quality prediction. The study introduces the use of quantum Support Vector Machines (SVM) for predicting air quality. It emphasizes the novel method of choosing the best quantum feature maps. Through the utilization of quantum-enhanced feature mapping, our objective is to exceed the constraints of classical SVM and achieve unparalleled levels of precision and effectiveness. We conduct precise experiments utilizing IBM’s state-of-the-art quantum computer cloud to compare the performance of conventional and quantum SVM algorithms on a shared dataset.

Introduction: Isatin, a heterocycle scaffold, is the backbone of many anticancer drugs and has previously been reported to engage multiple cellular targets and mechanisms, including angiogenesis, cell cycle, checkpoint pathways and multiple kinases. Here, we report that a novel isatin derivative, 5i, degrades estrogen receptor alpha (ERα) in estrogen-dependent breast cancer cells. This effect of the isatin nucleus has not been previously reported. Tamoxifen and fulvestrant represent standard therapy options in estrogen-mediated disease but have their own limitations. Isatin-based triple angiokinase inhibitor BIBF1120 (Nintedanib) and multikinase inhibitor Sunitinib (Sutent) have been approved by the FDA.Methods: Keeping this in view, we synthesized a series of N'-(1-benzyl-2-oxo-1, 2-dihydro-3H-indol-3-ylidene) hydrazide derivatives and evaluated them in vitro for antiproliferative activities in MCF-7 (ER+) cell line. We further investigated the effect of the most potent compound (5i) on the Erα through Western Blot Analysis. We used in silico pharmacokinetics prediction tools, particularly pkCSM tool, to assess the activity profiles of the compounds.Results and discussion: Compound 5i showed the best antiproliferative activity (IC50 value; 9.29 ± 0.97 µM) in these cells. Furthermore, 5i downregulated ERα protein levels in a dose-dependent manner in MCF-7. A multifaceted analysis of physicochemical properties through Data Warrior software revealed some prominent drug-like features of the synthesized compounds. The docking studies predicted the binding of ligands (compounds) with the target protein (ERα). Finally, molecular dynamics (MD) simulations indicated stable behavior of the protein-ligand complex between ERα and its ligand 5i. Overall, these results suggest that the new isatin derivative 5i holds promise as a new ERα degrader.

Objective: To study the pattern of presentation, diagnosis and management outcome of ureteric injury sustained during obstetric and gynaecological surgery. Study Design: Case series. Place and Duration of Study: Armed Forces Institute of Urology Combined Military Hospital, Lahore Pakistan, from Nov 2010 to Nov 2020. Methodology: Eighty-three patients satisfying inclusion criteria (suspected ureteric injury after gynaecological/obstetric intervention) were included. Demographic details, primary surgeon, presenting features, diagnostic workup, treatment instituted, complications, and success were recorded and analyzed. Results: The study analyzed 83 patients with a mean age of 44.6±10.8 years and a mean parity of 3.4±1.4 children. The ovarian tumour was the most common cause of primary surgery (32, 38.6%), and the majority (64,77.1%) involved less experienced gynaecologists. Flank/abdominal pain was the main presentation (56, 67.5%), followed by oliguria. The left ureter was affected in the majority (58, 69.9%). Ureteric re-implant (37, 44.5%) and JJ stenting (33, 39.8%) constituted major urological interventions. Only three patients (3.6%) had surgical failure; two of them died, while one had redo surgery. Conclusion: Iatrogenic ureteric injury mostly follows radical gynaecological procedures and must be suspected in case of pain in the abdomen or vague constitutional symptoms after pelvic surgery. Management is dictated by location, time interval, diagnosis, and available surgical expertise.

BackgroundOperating teams can decrease the likelihood of patient risk by using the WHO Surgical Safety Checklist. To ascertain the impact of demographic factors on behaviorally anchored ratings and investigate operating room (OR) staff attitudes toward checklist administration, we set out to better understand how OR personnel use the checklist in a tertiary care hospital in Pakistan.Materials and methodsA monocentric sequential mixed-methods study employing a quantitative approach of using World Health Organization Behaviorally Anchored Rating Scale (WHOBARS) assessments of surgical cases by OR personnel and two independent observers, who were certified surgeons having extensive experience in the rating of the WHOBARS scale for more than 1 year, followed by a qualitative approach of staff interviews were carried out in a tertiary care setting. In June and July 2022, over the period of 8 weeks, an intervention (training delivery) was implemented and evaluated. The information, skills, and behavior adjustments required to apply the checklist were taught in the course using lectures, videos, small group breakouts, participant feedback, and simulations.ResultsAfter the introduction of WHOBARS, 50.81% of respondents reported always using the checklist, with another 30.81% using it in part. Participants' years in practice, hospital size, or surgical volume did not predict checklist use. Checklist use was associated with always counting instruments (51.08%), patient identity (67.83%), difficult intubation risk (39.72%), the risk of blood loss (51.08%), prophylactic administration of an antibiotic (52.43%), and the use of pulse oximeter (46.75%). Interviewees felt that the checklist could promote teamwork and a safe culture, particularly enabling speaking up. Senior staff were of key importance in setting the appropriate tone.ConclusionThe use of a multi-disciplinary course for checklist implementation resulted in 50.81% of participants always using the checklist and an increase in counting surgical instruments. Successful checklist implementation was not predicted by the participant's length of medical service, hospital size, or surgical volume. If reproducible in other countries, widespread implementation in LMICs becomes a realistic possibility.

The construction industry encounters significant challenges in effectively managing solid waste produced during the extraction and production of building materials. In different countries, slurry waste generated from granite and marble processing industries, such as glass industry waste, constitutes a considerable portion of the total solid waste. Its undesirable disposal is causing unprecedented environmental damage. Using these non-biodegradable wastes to produce building materials would reduce the environmental burden and contribute to sustainable construction. This study, in detail, investigates the feasibility of utilizing Granite Powder (GP), Ground Granite Powder (GGP), and Ground Glass Waste (GGW) as partial replacements of components in blended mortar mixes. The mix modifications consist of partial replacement of cement with GGW, GP, and GGP in the range of 5–15% and fine aggregate replacement with Marble powder (MP) in 10–30% by mass. The mechanical, physical, and microstructure properties of blended and control mortar mixes were studied on the 3rd, 7th, 28th, and 91st curing days. The results demonstrate that the partial substitution of 10% GGW and 5% GP with cement and 10% MP with fine aggregates in blended mortars enhance the compressive strength at the later curing age (28 and 91 days) compared to that of a control mortar, which is associated to the development of higher pozzolanic reactivity. The XRD results showed the formation of the lowest content of calcium hydroxide (CH) and the highest content of calcium silicate gel in the blended mortars compared to the control mortar. The results enrich the data available in the literature not always univocal, as in the case of using marble and glass waste, providing also interesting information about the influence of granite powder on the hydration process in a mortar mix actually missing.

Steganography is one of the oldest methods for securely sending and transferring secret information between two people without raising suspicion. Recently, the use of Artificial Intelligence (AI) has become simpler and more widely used. Since the emergence of natural language processing (NLP), building language models using deep learning has become more. Furthermore, because of the importance of concealing secret information in delivered messages, Artificial Intelligence theories along with Natural Language Processing algorithms were employed to conceal secret information within the text cover. The Arabic language was used because of its large number of words, vocabulary, and linguistic meanings, and its most significant feature is Arabic poetry. This study discovered a new way to hide secret data inside newly formulated Arabic poetry based on previous Arabic poetic texts and a database of a number of Arab poets from the ancient and modern eras using Artificial Intelligence and Long Short-Term Memory (LSTM) theories to increase storage capacity by 45 percent. The linguistic accuracy and volume of secret data hidden within the formulated poetry were increased using a Baudot Code algorithm, where the secret data is hidden at the level of letters rather than words, and the linguistic accuracy and volume of secret data hidden within the formulated poetry were increased to eliminate the drawbacks found in previous studies.

Objective: To compare the efficacy of 5% potassium hydroxide (KOH) and 10% potassium hydroxide (KOH) solution for the treatment of molluscum contagiosum at a tertiary care Hospital. Study Design: Quasi-experimental study. Place and Duration of Study: Dermatology Department, Tertiary Care Hospital Karachi, from Oct 2019 to Apr 2021. Methodology: Sixty patients with molluscum contagiosum who fulfilled the inclusion and exclusion criteria were enrolled in the outpatient department of tertiary care hospital in Karachi. Patients were divided into two groups, A (5% KOH) and B (10% KOH) of 30 patients each. Potassium Hydroxide (KOH) solution was applied at home using the cotton-tipped applicator twice daily. Follow-up of patients was done at 2-weekly intervals for 12 weeks. Efficacy was measured based on the resolution of lesions or improvement from baseline. Results: Complete response occurred in 23 (76.7%) cases in 10% KOH Group while 6 (20%) in 5% KOH Group, Partial response occurred in 6 (20%) in 10% KOH group while 15 (50%) in 5% KOH group, No response occurred in 1 (3.33%) in 10% KOH group and 9 (30%) in 5% KOH group (p

Objectives. Spinal cord injury (SCI) is defined as damage to spinal cord that result in loss of sensory, motor and autonomic function. With advancement in medical profession, it is reported that the death rate of SCI patients decreases, and patients survive after initial injury therefore, problem extends beyond patients to their family members. Caregiver is responsible to provide emotional, physical and functional support. As a result, burden on caregivers increases, which not only affected them physically but mentally as well. In this study we aimed to find out the mental burden among caregivers of spinal cord injured patients. Methods. Census was conducted among caregivers of SCI patients in paraplegic centre, Peshawar. Data was collected from 80 participants/caregivers, included both male and female. Zarit burden interview scale was used to gather data regarding mental burden from caregivers of SCI patients. SPSS version 25 was used for data analysis. Outcomes. In this study the number of participants who responded to this survey was 80 out of 86 participants. Among these 80 participants, 59 (73.75%) were male while 21 (26.25%) were female with mean age of 31.83 ± 12.050. Participants experienced different intensities of mental burden (11.3% no or little burden, 31.3% mild to moderate, 45% moderate to severe and 12.5% had severe burden. Response to question 3, 4, 20 and 21 was quite different from other questions in questionnaire. Significant difference between means of male and female caregivers regarding mental burden was calculated (p = 0.030). No significant difference between age and total score obtained was found (p = 0.116). Conclusions. Caregivers of SCI patients had moderate to severe level of burden. Response to certain questions in questionnaire was quite different from others. There was significant difference between means of male and female caregivers regarding mental burden and no significant difference between age and total score obtained was found in caregivers of SCI patients.

Civil structures were designed to carry a variety of loading during their service life, including fire hazards. As a result, providing fire safety to structural members is one of the most important tasks in civil infrastructure design. Steel structural members are subject to fire-induced damage or collapse due to their high heat conductivity and quick loss of strength and stiffness qualities. Furthermore, the failure in steel beams under the combined effects of bending, shear, and fire loading is poorly understood in the literature. A present study consists of experimental investigations on the fire response of steel beams under bending and shear dominant loading. The specimens have a constant length of 1250 mm. The total depth of the specimens was changed according to the section chosen: 4 in, 6 in, and 8 in (10 cm, 15 cm, and 20 cm). The results of tests show that beams can fail suddenly due to a high drop in yield and ultimate strength of the steel beam. the increase in temperature degree reduced greatly the yield and ultimate flexural strength of the steel beams with different sizes (for all groups). This reduction reached at some times to 50% for the ultimate strength capacity of the specimen. Shear strength is also affected greatly by fire exposure and the reduction reached to about 38%. Furthermore, the design strength capacity can only tolerate loads at low temperatures. This reduction in strength was noted under flexural and shear dominant loading. Moreover, the design strength capacity can withstand against loading at low-temperature degrees only.

Objective: To determine the thicknesses of retinal nerve fiber layer (RNFL) and macula by fourier-domain (FD) optical coherence tomography (OCT) in diabetic patients with end-stage renal failure (ESRF) undergoing hemodialysis. Study Design: Cross-sectional study. Place and Duration of Study: Pakistan Naval Ship, Shifa Karachi, from Jan 2019 to Jul 2019 Methodology: Fifty four patients presenting to nephrology department who met the inclusion criteria were included in the study. Macular and retinal nerve fibre layer thicknesses were compared pre and post 30 minutes of hemodialysis and their correlation (r=-0.89) with age, duration of hemodialysis and gender was examined. Pre hemodialysis temporal, inferior, average retinal nerve fibre layer thicknesses were observed thinner than Post hemodialysis. Results: Pre-hemodialysis macular thicknesses were thinner than post hemodialysis. Thinning of Macular and RNFL showed a negative relationship with age and duration of hemodialysis (r=-0.89 & -0.76). Temporal, superior quadrants and average retinal nerve fiber layer thickness values were found statistically different in pre and post 30 minutes hemodialysis examination (p-value = 0.002, 0.001 & 0.0021) while, nasal and inferior quadrants were found statistically insignificant. Whereas in macula, temporal and superior quadrants were found statistically significant (p-value=0.005 & 0.002) and nasal, Inferior and average thickness were found statistically insignificant (p-value = 0.0641, 0.0594 & 0.083). Conclusion: Macular and retinal nerve fiber layer thicknesses of patients receiving hemodialysis were less than the normal population. Age has no effect on these thinning. The duration of hemodialysis effects more than gender. Hemodialysis session causes a consistent.............

Crop wastes could be applied in conjunction with synthetic fertilizers to satisfy crop nutritional needs and enhance soil fertility. A field experiment was carried out during winter 2019–2020 at the AMK Research Farm (Palatoo) Mardan, KPK (Pakistan) to investigate the combined effect of phosphorous (PS) and organic sources (OSs) on wheat productivity under different irrigation regimes. The experimental factors were: two irrigation regimes (limited and full irrigation), three inorganic sources of phosphorus (triple super phosphate (TSP), single super phosphate (SSP) and di-ammonium phosphate (DAP)) applied at 90 kg ha−1, and three organic amendments (farmyard manure (FYM), mung bean residue (MBR), and canola residue (CR)) applied at a rate of 10 t ha−1. A control plot (no phosphorus or organic supply) was included. A randomized complete block design (RCBD) with three replications was adopted. Among the fertilization strategies, SSP + FYM outperformed all other P fertilizers combined with legume or nonlegume residues in terms of grains per spike−1 (52), thousand-grain weight (41.6 g), biological yield (9.7 t ha−1), and grain yield (4 t ha−1). Under full irrigation, improved yield, yield components, and profits were obtained compared to the limited irrigation regime. Three clusters were obtained after applying an Agglomerative Hierarchical Clustering (AHC), and Principal Component Analysis (PCA) conferred the positive effects of inorganic P with FYM on the wheat yield and its related parameters. This study indicated that the productivity of wheat under the SSP + FYM fertilization strategy was found to be more economical with respect to the benefit–cost ratio (BCR). The combined application of SSP + FYM was more profitable in terms of a higher BCR (3.25) than other treatments under the full irrigation regime.

We discuss a connection between the generalized Euler characteristic Eo(|VDo|) of the original graph which was split at edges into two separate subgraphs and their generalized Euler characteristics Ei(|VDi|), i=1,2, where |VDo| and |VDi| are the numbers of vertices with the Dirichlet boundary conditions in the graphs. Applying microwave networks which simulate quantum graphs, we show that the experimental determination of the generalized Euler characteristics Eo(|VDo|) and Ei(|VDi|), i=1,2 allows finding the number of edges in which the subnetworks were connected.

Objectives: Continuous cultivation of rice and wheat crops in rice–wheat cropping system has resulted in numerous edaphic, social and environmental problems. Nonetheless, increasing water scarcity is also threatening the sustainability of rice–wheat cropping system. Therefore, farmers are compelled to cultivate alternative crops, like maize for water saving and higher economic returns. However, limited is known for integrated management of nitrogen (N) in wheat and maize crops. This study investigated the impact of integrated N management on productivity and profitability of wheat-maize cropping system. Methods: The study was conducted at Agriculture Research Farm of Bahauddin Zakariya University, Mulan, Pakistan. Wheat and maize crops were cultivated with recommended N dose using inorganic and organic sources, either alone or in combination with biofertilizer, while no N application was regarded as control. Data relating to root biomass yield and soil organic carbon (SOC) were collected. Results: Organic fertilizer alone and in combination with inorganic fertilizer and biofertilizer significantly improved root biomass and SOC. Improved SOC and crop root system resulted in better productivity of wheat-maize cropping system. Sole inorganic fertilizer application improved crop yield; however, had almost no effect on SOC. Integrated N management strategy (50% organic and inorganic fertilizer in combination with biofertilizer), improved crop yield (7168, 6405 kg/ha), net benefit (US$ 779, 961) and SOC (2.75%, 1.59%) for maize and wheat crops, respectively. Conclusion: Integrated N management strategy using different N sources seemed a viable and economically sound alternative of conventional N management, which would further strengthen the sustainability of wheat-maize cropping system.

Hemangiomas are benign vascular lesion, most commonly seen in liver and skin whereas rarely found in genitourinary system. In genitourinary tract urethral hemangiomas are mostly found in males. A case of uretheral hemangioma in 18 years old boy who presented with history of painless bleeding per urethra since age of 3 years. Cystoscopy revealed multiple sub centric lesions in anterior urethra distal to verumontenum. Patient was treated with cystoscopic fulguration using diathermy. He started bleeding again on 3rd postoperative day, so intralesional triamcinolone was given. On follow up at one and three months he was asymptomatic.

Tomato is considered as a valuable vegetable crop all over the world. It prefers loose, well drained loamy soils rich in organic matter. In Pakistan, mostly soils are calcareous in nature. In calcareous soils, the production of tomato crop is low because of zinc deficiency. Therefore, current study was aimed to examine the potential of foliar application of zinc oxide in tomato cultivar Tiny Tim Cherry in calcareous soil conditions. In the current study, all the studied traits i.e. plant height, stem diameter, number of branches per plant, number of leaves, number of flowers per plant, fruit weight and yield per plant were significantly higher after foliar application of zinc oxide (30 ppm) and significantly lower in controlled treatment as compared to other treatments of zinc oxide. The maximum total soluble solids (TSS), chlorophyll A, chlorophyll B, vitamin C, flavonoids, carotenoids and phenolics were recorded in plants treated with 30 ppm of zinc oxide as compared to other treatments. However, the highest acidity was calculated in 10 ppm, while the lowest acidity was measured in 0 ppm (control). Conclusively, foliar application of Zn has potential to increase the nutritional components of tomato fruits.

Xanthine urolithiasis is usually a benign condition, easy to prevent or cure by appropriate alkalinization, forced hydration and restriction of dietary purines if diagnosed early. When unrecognized, xanthinuria can lead to end-stage renal failure or nephrectomy.

Majority of Pakistani soils are deficient in phosphorus. Phosphorus is usually applied in form of synthetic fertilizer. However integrated use of P from synthetic and organic sources can be more profitable and beneficial on sustainable basis. Field trials were conducted at research farm University of Poonch, Rawalakot, AJK, Pakistan for two consecutive years to check the comparative effects of synthetic fertilizer and organic manures applied alone and in combinations on the phosphorus use efficiency (PUE), wheat yield and yield components. Shafaq-06 cultivar of wheat was used as test cultivar. Ten treatments were included: (I) Control (P0) without application of fertilizer; (II) SSP @ 60 kg/ha (P60SSP); (III) SSP @ 90 kg/ha (P90SSP); (IV) SSP @ 120 kg/ha (P120SSP); (V) PM @60 kg/ha (P60PM); (VI) PM @90 kg/ha (P90PM); (VII) PM @120 kg/ha (P120PM); (VIII) SSP @30 kg/ha + PM @30 kg/ha (P30SSP+30PM); (IX) SSP @45 kg/ha + PM @45 kg/ha (P45SSP+45PM); (X) SSP @60 kg/ha + PM @60 kg/ha (P60SSP+60PM) which were laid out under the Randomized Complete Block Design. Significantly higher values for yield of grain (2397 kg/ha) was recorded with PM + SSP @ 60 kg P2O5 ha-1 each. Likewise, FPUE, PIR of wheat and AFPUE was quite higher with combined use of PM and SSP i.e. P60SSP+60PM treatment. Additionally, increase in PUE, wheat yield and yield components associated with combined treated plot would help to minimize the use of high cost synthetic mineral fertilizers and represents an environmentally and agronomically sound management strategy.

We show that there is a relationship between the generalized Euler characteristic Eo(|VDo|) of the original graph that was split at vertices into two disconnected subgraphs i=1,2 and their generalized Euler characteristics Ei(|VDi|). Here, |VDo| and |VDi| denote the numbers of vertices with the Dirichlet boundary conditions in the graphs. The theoretical results are experimentally verified using microwave networks that simulate quantum graphs. We demonstrate that the evaluation of the generalized Euler characteristics Eo(|VDo|) and Ei(|VDi|) allow us to determine the number of vertices where the two subgraphs were initially connected.

Percutaneous nephrolithotomy (PCNL) is one of the important options in the management of large (>2 cms) and complex renal calculi. Traditionally the prone position has been used to access the pelvicaliceal system. It has its advantages and disadvantages as well. Several modifications to this position have been suggested and reported by several urologists. We had performed PCNL in an elderly female in classical prone position with severe kyphoscoliosis and solitary functioning kidney.

Though addressed widely by academicians and researchers across the globe, the subject of counterfeiting dates back to historical times of 27BC. In academic literature, the discussion on counterfeit(ing) began a century back when researchers started to define its boundaries through their understanding. Ranging from the classical descriptions on counterfeit, counterfeiting, counterfeit trade and counterfeit product(s), this article intends to use text analysis technique to provide the reader with a summary of the existing academic literature on the aforementioned subjects. It summarizes key definitions from the respective area with a broader aim to bridge the gap in the existing counterfeiting and counterfeit product-related literature by providing a brief (yet ample) list on counterfeit(ing). Moreover, it also identifies the key similarities exiting in the definition set. The article concludes with authors own definition of counterfeiting and counterfeit product(s) based on the conceptualization developed through the understanding of combined definitions from the literature.

This study aims to examine how social undermining restrains employee creativity. Specifically, an attempt is made to investigate the serial mediating role of interpersonal distrust and knowledge hiding in the relationship between social undermining and employee creativity. This study used purposive sampling to draw 309 employees from the advertising agencies of Pakistan. We used a time-lagged research design to collect the data on the measures at three different points in time. A self-administered questionnaire was used for the collection of data. We followed variance-based structural equation modeling (SEM) to conduct the data analysis in SmartPLS. Our study results indicated a significant negative association between social undermining and employee creativity, while serial mediation analysis showed that interpersonal distrust and knowledge hiding partially mediated the above linkage. This study’s findings contribute to the literature on employee creativity by identifying and testing social undermining as an interpersonal inhibitor factor that impairs employee creativity, and this relationship is serially mediated by interpersonal distrust and knowledge hiding. This study offers valuable insights for the managers of advertising agencies.

The purpose of this paper is to analyze the impact of terrorism-induced fear on employee job attitudes and absenteeism in the weeks following the Army Public School attack in Peshawar, Pakistan. The paper is based on questionnaire data collected from 204 faculty members of public sector universities in Peshawar using snowball sampling technique. We applied partial least squares structural equation modeling (PLS-SEM) to analyze the entire impact path and found substantial support for our hypotheses. The results suggest that fear of terrorism affects absenteeism directly, as well as indirectly via job attitudes. Further, perceived organizational support is found to attenuate the negative relationship between fear of terrorism and job attitudes. Very few studies have examined the impact of societal variables such as national traumatic events on jobrelated outcomes.

The aim of this study was to investigate the direct and indirect effects of protean career attitude on subjective and objective career success representing personal outcomes and task performance reflecting an organizational outcome. Drawing on the intelligent career framework, three knowing career competencies, i.e., career insight (knowing why), networking (knowing whom), and career/job-related skills (knowing how), were hypothesized as mediators linking protean career attitude with its personal and organizational outcomes. Participants of the study were 241 faculty members and matched supervisors from five large public sector universities in Islamabad, Pakistan. Data were collected in two waves through a personally administered questionnaire and analyzed through covariance-based structural equation modeling (CB-SEM). Results showed that protean career attitude has direct positive impacts on subjective career success, objective career success, and task performance. Further, the mediating role of three knowing career competencies was partially supported. We contribute to the literature by proposing and testing a research model linking protean career attitude with its personal and organizational outcomes directly and indirectly through three ways of knowing. A number of practical implications along with future research directions are also discussed.

Soil compaction is a global issue pertaining to agricultural lands. The frequent use of farm machinery and field operations at the same depth are the major causes of soil compaction. The gradual increase in soil compaction deteriorates maize grain quality due to reduced nitrogen (N) uptake. Quality food production by reducing soil compaction is the need of time, which can be achieved through deep tillage and N management. In this study, three tillage systems viz. conventional tillage (using cultivator), tillage with mould board plough +2-cultivations (MBP), and tillage with chisel plough +2-cultivations (CP); and three nitrogen levels viz. 100, 150 and 200 kg ha–1 were used to evaluate their effect on soil properties, N uptake and grain quality in maize. Lower bulk density (1.41 Mg m–3), higher total porosity (0.47 m3 m–3) and higher nitrogen uptake (96.01 kg ha–1) was recorded under chisel plough (CP) compared with other tillage systems. Different N levels had significant effect on grain and total N uptake and grain quality, while soil properties remains unaffected. Higher N uptake was recorded with 200 kg ha–1 N application than other treatments. Similarly, 8.51% and 8.57% more grain protein contents were recorded with 200 kg ha–1 N during first and second year respectively. Unlike grain protein, starch and oil contents were negatively affected by N application being higher starch (71.7%) and oil contents (3.41%) with less N supply (100 kg ha–1). However, interaction effect of tillage and nitrogen levels was found non-significant for all studied parameters except for oil contents. Higher oil contents were recorded with MBP along with 100 kg ha–1 N application. Overall study indicated that deep ploughing with CP is important for maize to explore more soil area for nutrient uptake and N is also important for improving grain quality especially protein contents an important food constituent.

Compound and composite of the (NiO) _0.25 (Fe _2 O _3 ) _0.75 nanoparticles have been prepared by without water and surfactants (WOWS), Sol-gel method. Synthesized nanoparticles are calcined at 500 °C/2 h and pellets are sintered at 550 °C/1 h. The compound and composite showed cubic lattice and rhombohedral crystallographic lattices respectively. Morphological analysis is done by Scanning electron microscope and Transmission electron microscope. UV characterization was done to calculate band gap energies for both samples. DC electrical conductivity as a function temperature from 373.15 to 703.15 K was done by two-probe method. DC conductivity has been explained by hopping mechanism. Activation energies were calculated from Arrhenius plots. AC electrical properties namely; dielectric constant, dielectric loss tangent, ac conductivity and impedance were measured as a function of frequency (20 Hz–3 MHz). AC electrical properties were explained by Maxwell-Wegner model, Koop’s theory and Johnsher’s power law. Composite of (NiO) _0.25 (Fe _2 O _3 ) _0.75 showed enhanced properties as compared to compound.

Organizations need to be innovative for their long-term survival and this can be achieved when their employees demonstrate innovative behaviors at the workplace. Innovative behavior has thus received considerable attention from researchers, particularly on exploring the factors which foster employee innovative behaviors. Based on human resource system strength theory, the objective of this study is twofold. First, it examines the direct and indirect relationship between perceptions of performance appraisal quality (PPAQ) and innovative behavior mediated through psychological empowerment. Second, it examines the moderating effect of perceptions of HRM system strength in the hypothesized links. A total of 360 faculty members participated in the study from twelve public sector higher education institutes in Islamabad, Pakistan. Partial least squares structural equation modeling (PLS-SEM) is used for statistical analysis of the quantitative data collected through self-administered questionnaire. Results demonstrated that PPAQ is positively related with innovative behavior. The findings also support the mediating role of psychological empowerment and the moderating role of perceptions of human resource management (HRM) system strength. We contribute to the literature by demonstrating that HRM content and process are two complementary facets of an HRM system in bringing out positive work behaviors. A number of practical implications and directions for future research are outlined.

The main purpose of this study was to investigate reciprocal relationships between abusive supervision, subordinates' emotional exhaustion, and job neglect, and to examine the mediating role of emotional exhaustion in the cross-lagged relationship between abusive supervision and job neglect. Besides, we tested the moderating role of self-compassion in the cross-lagged relationship between abusive supervision and emotional exhaustion. We applied a two-wave cross-lagged panel design with a time lag of six months. Participants were 331 staff nurses of public sector hospitals in Islamabad, Pakistan. Data were collected using a self-report questionnaire at two points in time. Longitudinal structural equation modeling (SEM) was used to compare nested models. Results of cross-lagged SEM analyses supported the posited reciprocal model, indicating that abusive supervision, emotional exhaustion, and job neglect are mutually related. Results of mediation analysis showed that emotional exhaustion partially mediates the cross-lagged relationship between abusive supervision and job neglect.
