Towards the development of green energy devices, it is necessary to focus on commercial electrolyte materials for intermediate temperature solid oxide fuel cells (IT-SOFCs).

Introduction: Oxidative stress is a normal phenomenon in normotensive pregnancy; however, in preeclampsia, oxidative stress is exaggerated may result in a greater potential for endothelial oxidative damage. It has been reported that higher MDA (Malondialdehyde) /total antioxidant capacity (TAC) ratio is indicative of oxidative stress in women with pre-eclampsia. Materials and Methods: Prospective study was done for duration of 2 years i.e, from January 2015 to December 2017 in the department of Biochemistry at Kakatiya Medical College, Hanmakonda, CKM hospital Warangal. A total number of 60 pregnant women were included in the study. Among these, 20 pregnant women were clinically diagnosed as pre-eclampsia and 20 are eclamptic cases and the remaining 20 were selected as control group and are normotensive antenatal women who are also in third trimester of pregnancy. Results: The mean MDA, serum uric acid, 24 hr urinary protein were higher in pre-eclampsia and eclampsia compared to controls. Conclusion: Increased lipid peroxidation products levels clearly shows that oxidation stress is more in pre-eclampsia and eclampsia than in control subjects and it plays a significant role in etiopathogensis of PIH. Serum uric acid levels are significantly higher in cases than in controls and by estimating the uric acid levels we can assess the severity of the disease and we can avoid further progress of the disease process by early detection and prompt treatment. Total serum protein levels are drastically reduced in pre-eclampsia and eclampsia cases compared to controls. Keywords: MDA, Serum uric acid, Proteins, Eclampsia, Pre-eclampsia.

Cytokine storm an uncontrolled over-production of soluble markers of inflammation which is systemic inflammatory response, is a major responsible for the occurrence of ARDS. Animal studies that have implicated ACE2 in the acute lung injury caused due to SARSCoV. It has been hypothesized that ACE2 causes ALI by bringing about autophagy through the AMPK/mTOR pathway. Metformin works through AMPK activation, which leads to phosphorylation of ACE2 and there is an structural change which unables SARS CoV2 to bind with it also it is known that metformin can reduce CRP level.This study aim to find the role of metformin in COVID 19 on disease regression by both clinical assessment and laboratory values.Single blinded randomised controlled trial, parallel group, placebo controlled study for 1 month duration at tertiary health care centre. There is significant clinical improvement in 69% of the subjects at day 6 and 31% at day 7 in metformin group. Also there is effective reduction in CRP level whereas Sr.Ferritin levels are moderately reduced. There is no adverse effect during study period.

Test anxiety is a typical experience in classrooms, changing the performance of students from school for college, as a whole being adults who must take job-related exams. Test anxiety can also move termed as anticipatory anxiety, examination anxiety that occurs in a situation like facing the exam. Indeed, there is a stirred upstate in physiological level causing over-arousal, tension and somatic symptoms and psychological level causing poor attention, deterioration in perception and thought fluency this can lead to worry, dread, fear of failure, and catastrophic experiences before or during test situations among the students. In this context, the research attempted to study the present problem, i.e., Text Anxiety about Academic Achievement of Kasturba Gandhi Balika Vidyalaya(KGBV) students. For the study, the researcher identified 100 students studying (8th and 9th standard) in KGBV schools of Kuppam and Gudipalle Mondal of Chittor district of Andhra Pradesh.

Carbon plasma immersion ion implantation (PIII-C) has been performed on Ni−Ti alloy surface using methane as a precursor gas at low temperature and it has been followed by deposition of diamond-like carbon (DLC) coating. Untreated and coated alloys are characterized with field emission scanning electron microscopy, atomic force microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy. Electrochemical impedance spectroscopy, and corrosion testing in Hanks’ solution which is simulated body fluid show that corrosion resistance has been enhanced in PIII-C + DLC-coated alloy compared to untreated alloy. The in vitro studies of untreated and PIII-C + DLC-coated alloys have been evaluated using osteoblast-like cells (MG-63). Cellular behavior in terms of cell morphology along with the viability and cell spreading has been evaluated using scanning electron microscopy and in vitro cell culture assay, respectively. In comparison to Ni–Ti alloy, the coated alloy exhibits better cell viability indicating their biocompatibility

In this work, alumina (Al2O3) reinforced with zirconia viz., 0, 3, and 8 mol% yttria doped (i.e., ZrO2, 3YSZ, and 8YSZ), and 4 wt% carbon nanotube (CNT) are coated on Inconel 718 substrate by atmospheric plasma spraying (APS). Reinforcement by CNT and 3YSZ has led to a substantial enhancement in the fracture toughness from 3.89 MPa m1/2 (for Al2O3) to 5.90 MPa m1/2 in the reinforced composite. It is observed that CNT has contributed ∼5–12% toughness enhancement, whereas ∼15% contribution to toughening is obtained via tetragonal to monoclinic (t→m) transformation of zirconia. Moreover, CNTs not only assist the t→m transformation but also enhance the toughness value of Al2O3-based thermal barrier coatings (TBC) near to its upper theoretical bound estimated using modified fractal model. Moreover, the effective thermal conductivity is estimated using modified theoretical models embracing the aligning factor of CNT in APS coatings, which unequivocally confirms the superiority of Al2O3 reinforced with 3YSZ and CNT as a potential TBC.

The usage of non linear loads in recent days are becoming vast that gives an alarm signal to power system and power engineers in terms of quality of power. As a result of large amount of non-linear power electronic equipments harmonic distortion is frequently encountered by the utilities in each day. The purpose of active filter is to eliminate the harmonics present in the electrical signal ensuing in sustaining the quality of the power supply in the system. DSP controlled Shunt Active Filter is used in this paper to eliminate harmonics and compensate reactive power caused by nonlinear load. Discrete Fourier Transformation is used to generate reference source current. The firing pulses for shunt active filter are generated based on a hysteresis based current controller implemented in a DSP controller, so that SAF allows elimination of the harmonics and compensation of reactive power component of load current, ensuing in a supply current which is purely sinusoidal. Simulation results of the proposed SAF to meet the requirements of IEEE-519 standards are given.

Protective alumina thin films of different thicknesses (35–95 nm) were grown by pulsed RF magnetron sputtering technique at room temperature on germanium (Ge) coated black polyimide or Kapton® substrate which is often employed as sunshield membrane on communications satellite antennas. The thin alumina top layer provides shielding of Ge coating from degradation during storage. The alumina thin film was characterized by X-ray diffraction, field emission scanning electron microscopy and X-ray photoelectron spectroscopy (XPS) techniques to investigate microstructural and electronic characteristics. Thermo-optical properties such as IR emittance, solar absorptance, reflectance and transmittance and electrical property e.g. sheet resistance of the deposited alumina films were measured. The RF losses e.g. insertion loss and return loss were measured in both Ku band (10.5–14.5 GHz) and Ka band (27–40 GHz). Finally, to prove anti-degradation behavior of alumina thin film, water droplet spreading experiments were carried out and evaluated its chemical degradation by XPS.

Displays of prosocial behaviour also have been related positively to other socially competent outcomes, including social acceptance and approval among classmates and being liked by teachers. Most of them assume that cognitive and affective skills such as perspective taking, prosocial moral reasoning, adaptive attributional styles, perceived competence, and emotional well-being provide a psychological foundation for the development of prosocial behaviour. Individual differences such as genetic and temperament characteristics also have been place the importance of school prosocial behavior and it is typically evidenced by its vision or mission statement - documents declaring the importance of, and expectations for, school-based prosociality. It is clear that prosocial behaviour is highly valued by teachers and school personnel, as well as by children themselves. In addition, prosocial behaviour has received recent increased attention by educators due in part to interest in promoting positive aspects of psychological functioning and adjustment rather than treating maladaptive forms of classroom behaviour once they occur. At the school-level, utilization of curricula and primary prevention activities to promote prosocial behaviour in all classrooms also should be considered. Finally, school-initiated parent involvement programs should highlight practices that can promote the development of prosocial behaviour at home including the use of inductive reasoning and parental modeling of positive social interactions. Prosocial behaviour is a hallmark of social competence in teachers of all ages. However, it is clear that the developmental and socialization foundations of positive behaviour are rooted in teachers. The importance of prosocial behaviour is supported by evidence that positive forms of behaviour are related positively to a range of psychological and emotional processes, to other socially competent outcomes and to intellectual accomplishments in teachers., {"references":["1.\tBrown, S.

Early childhood is one of the most crucial and formative period in the life of any individual. Many psychologists believed that the first six years in the life of an individual is very significant period in the developmental stages especially its lays foundation for healthy and wholesome development of the personality. The research studies proved that pre-school education plays a crucial role in the development of young children before they enter into formal schooling. The pre-school education prepares the child for tomorrow and also helps in his/her cognitive development. Pre-school education is considered to be very significant for the child as it is the first step towards enterning into the world of knowledge as well as a healthy person. It aims at satisfying the Childs physical, mental, emotional and social needs. Pre-school education helps in laying down a healthy foundation for the all round development of the child. It allows the children to expose their inner skills and talents, so that the children develop their personality. It also provides opportunity to the children to give vent to their inner desires in a positive way.

Cognitive radio (CR) has become a key technology for addressing spectrum scarcity. In CR networks, spectrum access should not interfere the incumbent networks. Due to the requirement above, common control channel approaches, which are widely used in traditional multichannel environments, may face serious CR long-time blocking problem and control channel saturation problem. Although channel-hopping-based approaches can avoid these two problems, existing works still have significant drawbacks including long time-to-rendezvous, unbalance channel loading, and low channel utilization. This paper tends to the issue of range mindful survivable methodologies with disappointment likelihood limitations under static activity in adaptable transfer speed optical systems. The joint disappointment likelihood amongst essential and reinforcement ways must be beneath the most extreme fair joint disappointment likelihood for each activity request. It creates whole number direct program (ILP) models for committed way security and shared-way assurance with a specific end goal to limit the aggregate number of recurrence spaces expended, and furthermore propose a range mindful devoted insurance (SADP) calculation and a range mindful shared security (SASP) calculation. This demonstrates the ILP show arrangements devour least number of recurrence spaces, however prompt higher normal joint disappointment likelihood contrasted with the SADP and SASP calculations. In addition, both the SADP and SASP calculations accomplish a superior execution as far as aggregate number of recurrence openings expended when contrasted with a customary devoted way insurance calculation and an ordinary shared-way assurance calculation, separately, however prompt higher normal joint disappointment likelihood.

Obstructive sleep apnoea (OSA) is one of the most common public health problems in adults. Patients with OSA are prone for excessive adipose tissue deposition in the neck, which in turn, increases the upper airway narrowing. Of the imaging modalities available for assessing the upper airway, magnetic resonance imaging (MRI) is found to be useful technique for defining soft tissue abnormalities.We prospectively studied 50 patients presenting with OSA and 50 normal controls to evaluate the role of MRI cephalometry in the diagnosis of OSA and compared the cross-sectional area and antero-posterior diameter of the upper airway in the retro-palatal airway and retro-glossal areas by MRI cephalometry.In comparison with controls, cases had a significantly lower cross-sectional area and antero-posterior diameter of the upper airway in the retro-palatal airway and retro-glossal areas.Our observations suggest that MRI cephalometry is a sensitive technique for the diagnosis of OSA.

Hydrothermal synthesis of TiO2 colloids is based on hydrolysis and pressure treatment of titanium isopropoxide precursor in acidic solutions. The influence of the use of nitric and acetic acids during the synthesis was studied, showing a significant effect on the colloid crystal structure. Both dark-field TEM and phase transformation temperature measurements indicate that the colloids prepared in acetic acid contain more of the {101} face compared with the colloids prepared in nitric acid. The surface structure difference affects the performance of dye-sensitized solar cells that consist of electrodes made from these colloids. Better performance is achieved using the colloids prepared in nitric acid, indicating the importance of controlled colloid fabrication for higher conversion efficiencies.

The photocatalytic activity of combustion synthesized nanocrystalline CeAlO3 was determined for the degradation of four anionic and four cationic dyes. The perovskite oxide showed high-photocatalytic activity and a complete degradation of all the dyes was possible within 2 h. The photocatalytic activity of the compound was comparable with the activity of the commercial Degussa P-25 TiO2 catalyst. The degradation of dyes was found to follow first order kinetics and the first order degradation rate constants were determined.

A modified solution combustion technique was successfully used to synthesize sub-10 nm crystallites of hybrid CeO(2)-Al(2)O(3)-CeAlO(3). The fuel in the solution combustion was tuned to obtain mixed oxides and solid solutions of the compound. The compounds were characterized by X-ray diffraction, transmission electron microscopy and X-ray photoelectron spectroscopy. XRD and TEM analysis showed the substitution of Al(3+) ions in the CeO(2) matrix when a combination of glycine, urea, hexamine and oxalyl dihydrazide was used as fuel for the synthesis. The compounds showed high activity for CO oxidation and the activity of the compounds was dependent upon the composition of the oxide.

The integration of our lives with internet, smartphones and wearable devices has made interferences (such as interruptions and distractions) pervasive. This research investigates the impact of such interferences on information processing, and on downstream effects related to product evaluation and choice. In essay 1, we explore the affective characteristics of interruptions (while previous research has looked at the non-affective characteristics). It is found that affective interruptions lead to higher contrast in otherwise similar products, and that the direction of contrast depends on the valence (positive/ negative) of the interruption. Contrasting interruptions with breaks (planned and expected interferences) reveals that it is not only the content but also the manner (random, unexpected and externally generated) of interruptions that lead to the observed effects. In essay 2, we contrast interruptions and distractions on cognitive (attentional load) and affective characteristics. It is found that distractions produce higher attentional load than interruptions, leading to higher focus on global/ heuristic aspects of product information. On the other hand, interruptions produce stronger affective reactions than distractions, leading to stronger (favourable or unfavourable) evaluation of post-interference products. Moderation of brand strength on the aforementioned main effects is also explored, along with a field study to assess the effects in a real-world setting.

Recent years have seen growing use of ‗Roadblock Advertising‘ by media planners to enhance advertising effectiveness. Many companies (Hutch, Aircel, ITC, Viacom 18, Nestle, Nokia, Volkswagon, Real fire extinguisher, Vodafone, Wagh Bakri) have invested in Roadblock advertising in the recent past. Roadblock advertising is characterized by blocking of particular media vehicle(s) for the airtime or advertising space by a single advertiser for a certain period of time. The objective of Roadblock advertising is to break the clutter of advertisements in order to be heard, read or watched exclusively by viewers. While Roadblock advertising is perceived as effective by many practitioners, from the audience‘ point of view Roadblock advertising might be upsetting their viewing experience, and this annoyance might be affecting their attitude towards the advertisement. This makes the phenomenon of Roadblock advertising worth investigating for the benefit of managers and advertisers, as they are committing hefty budgets (Appendix G). The purpose of this research is to understand how Roadblock advertising differs from the non-Roadblock or usual advertising repetition formats in its impact which will help managers to better invest the advertising budget. There is a scarcity of literature on the impact of ―Roadblock Advertising‖ on brand recall and attitude of viewers as a result of such advertising campaigns. This research proposes to address this gap. Specifically, two essays are proposed to explore the effectiveness of Roadblock advertising campaigns and effectiveness of such campaigns for familiar and new brands. The literature for this study has been developed from the existing body of literature in the area of advertising, psychology, learning, and neuroscience. For the development of hypotheses, the theories have been borrowed from advertising and psychology literature. The findings of this research are expected to bring new insight into both theory and the managerial practice for effective Roadblock advertising.
