Killing Symmetry in Special Axially Symmetric Static Spacetimes in Teleparalel Theory of Gravitation

In this paper we are searching for teleparallel Killing vector fields of special axially symmetric static spacetimes in teleparallel theory of gravitation by using direct integration and algebraic techniques. After thorough investigations, the whole problem is divided into three cases under different constraints. Two of the said cases give contradiction, while one of them gives the solution of the system comprising the killing equations in the form of killing vector fields. The dimension of the killing symmetry in this case is 10

The Role of Organization Culture in Predicting Organizational Effectiveness: A Case from Developing Countries

This study aims to extend cross-cultural research in examining the potential influence of organizational culture on organizational effectiveness in the context of higher education institutions of the province of Khyber Pakhtunkhwa, Pakistan. A non-experimental and cross sectional perceptual data was collected using survey questionnaire through the senior faculty members and administrators. Selection of the subjects was made on one of the most efficient probability sampling techniques namely disproportionate stratified random sampling.Further, the measurement instruments based on a competing values framework of renowned scholars in the field were adopted to tape both of the study variables. Grounded on collected data for direct effect of organizational culture on organizational effectiveness was empirically tested via multiple regression analysis. Overall, the resultant information of regression model revealed organizational culture as a significant predictor of organizational effectiveness. Moreover, out of four traits of organizational culture, two traits i.e., clan, adhocracy showed significant positive relationships to organizational effectiveness, while bureaucratic type of culture exhibited as inverse association and seemed in line of prior research.Contrarily, exception is noticed for market type of culture. Discussion of these findings followed by implications, limitations, direction for future research and conclusion are given subsequently in the article.Key words: Organizational culture; Competing Values Framework (CVF); Organizational effectiveness; Higher education institution

A novel driver emotion recognition system based on deep ensemble classification

Driver emotion classification is an important topic that can raise awareness of driving habits because many drivers are overconfident and unaware of their bad driving habits. Drivers will acquire insight into their poor driving behaviors and be better able to avoid future accidents if their behavior is automatically identified. In this paper, we use different models such as convolutional neural networks, recurrent neural networks, and multi-layer perceptron classification models to construct an ensemble convolutional neural network-based enhanced driver facial expression recognition model. First, the faces of the drivers are discovered using the faster region-based convolutional neural network (R-CNN) model, which can recognize faces in real-time and offline video reliably and effectively. The feature-fusing technique is utilized to integrate the features extracted from three CNN models, and the fused features are then used to train the suggested ensemble classification model. To increase the accuracy and efficiency of face detection, a new convolutional neural network block (InceptionV3) replaces the improved Faster R-CNN feature-learning block. To evaluate the proposed face detection and driver facial expression recognition (DFER) datasets, we achieved an accuracy of 98.01%, 99.53%, 99.27%, 96.81%, and 99.90% on the JAFFE, CK+, FER-2013, AffectNet, and custom-developed datasets, respectively. The custom-developed dataset has been recorded as the best among all under the simulation environment

Effects of Emblica Officinalis Extract Cream on Human Skin Trans-epidermal Water Loss Measured with Non Invasive Probe

The purpose of this study was to assess hydroalcoholic Emblica officinalis fruit extract cream on human skin trans-epidermal water loss (TEWL). Ten male volunteers were examined in this study. Measurements were made on cheeks. Creams with different concentrations of ABIL® EM 90 and liquid paraffin containing 3% hydroalcoholic Emblica officinalis fruit extract were developed and tested for stability studies for a period of 28 days. Selected cream and its base were further assessed in different conditions at 8 °C (in refrigerator), 25 °C (in incubator), 40 °C (in incubator) and 40 °C (in incubator) with 75% relative humidity (RH) for color, odor, thickness, grittiness liquefaction, phase separation, and pH at different time intervals. Trans-epidermal water loss (TEWL) was monitored every week by non-invasive bio-instrument Tewameter MPA 5. All measurements were made statistically by ANOVA and t-paired test. Significant decrease on skin TEWL was produced. Keywords: Hydroalcoholic Emblica officinalis fruit extract, Facial cream, Biophysical paramete

Patterns of suicide and self-harm in Pakistan: a retrospective descriptive study protocol

Introduction Suicide is a major global public health problem. Low-income and middle-income countries contribute 78% of all suicidal deaths. Pakistan, a South Asian country, lacks official statistics on suicides at national level. Statistics on suicide are neither collected nationally nor published in the annual national morbidity and mortality surveys. Medicolegal reports on suicides and self-harm are extremely rich and important source of information but greatly underused in Pakistan. We aim to examine the patterns of suicides and self-harm retrospectively in patients who were registered with medicolegal centres (MLCs) in Karachi, during the period January 2017 to December 2021. Methods and analysis Using retrospective descriptive design, the data will be collected from the medical records maintained at the main office of the Karachi police surgeon. Data from all nine MLCs of Karachi are collated and stored at the main office of Police surgeon. Information on suicide and self-harm cases will be extracted from records of all MLCs. The data will be collected using structured proforma and it will be analysed using descriptive and inferential analysis. Ethics and dissemination The study was approved for exemption from Aga Khan University, Ethical Review Committee. The findings of the study will be disseminated by conducting seminars for healthcare professionals and stakeholders including psychiatrists, psychologists, counsellors, medicolegal officers, police surgeons, mental health nurses, general and public health physicians and policy makers. Findings will be published in local and international peer-reviewed scientific journals

Islamophobia in the West and Post 9/11 Era

The concept of Islamophobia started from the crusade when Christianity challenged Islam. After the attack on World Trade Center, the West manipulated the concept and socialized its people about the fear and threat from Islam which actually does not exists because radical Islam or few people who are not practical Muslims, are not the representatives of whole Muslim states. The trade sanctions, misinterpretations on media about Islam, conflicts in Muslim states which are not resolved even in the presence of international organizations, are the hatred regimes by the West at intellectual level. Ideological dispersal, exploitation, wars, distortion by different ideological regimes and insurgency created within the Muslim society are the clear picture of hatred regime in the West against Islam. Thus, Islamophobia is now a fact rather than utopian idea. Secondary data sources along with the theory of social constructivism are being carried out in this paper.

Determination of genotype differences through restriction endonuclease in Camels (Camelus dromedarius)

Tyrosinase gene or C locus has long been implicated in the coat colour determination. This gene a copper-containing enzyme located on chromosome 11q14.3 is expressed in melanocytes and controls the major steps in pigment production. In camel, C locus a restriction site provoked by the T variant of the mutation was used in a special restriction fragment length polymorphism analysis (PCR-RFLP) for genotyping of camels from six different Pakistani camel breeds (Marecha, Dhatti, Larri, Kohi, Campbelpuri and Sakrai). Significant differences in the genotype frequency between the breeds were estimated. The Sakrai breed showed in comparison to other studied breeds a distinctly higher frequency of the homozygous with restriction genotype. The objective of the present study was to screen the camel breeds using modern genetic technique that have been so far classified on the basis of performance and tribal ownership.Keywords: Camel, genotype, restriction endonucleas

Whole exome sequencing identified five novel variants in CNTN2, CARS2, ARSA, and CLCN4 leading to epilepsy in consanguineous families

Introduction: Epilepsy is a group of neurological disorders characterized by recurring seizures and fits. The Epilepsy genes can be classified into four distinct groups, based on involvement of these genes in different pathways leading to Epilepsy as a phenotype. Genetically the disease has been associated with various pathways, leading to pure epilepsy-related disorders caused by CNTN2 variations, or involving physical or systemic issues along with epilepsy caused by CARS2 and ARSA, or developed by genes that are putatively involved in epilepsy lead by CLCN4 variations.Methods: In this study, five families of Pakistani origin (EP-01, EP-02, EP-04, EP-09, and EP-11) were included for molecular diagnosis.Results: Clinical presentations of these patients included neurological symptoms such as delayed development, seizures, regression, myoclonic epilepsy, progressive spastic tetraparesis, vision and hearing impairment, speech problems, muscle fibrillation, tremors, and cognitive decline. Whole exome sequencing in index patients and Sanger sequencing in all available individuals in each family identified four novel homozygous variants in genes CARS2: c.655G>A p.Ala219Thr (EP-01), ARSA: c.338T>C: p.Leu113Pro (EP-02), c.938G>T p.Arg313Leu (EP-11), CNTN2: c.1699G>T p.Glu567Ter (EP-04), and one novel hemizygous variant in gene CLCN4: c.2167C>T p.Arg723Trp (EP-09).Conclusion: To the best of our knowledge these variants were novel and had not been reported in familial epilepsy. These variants were absent in 200 ethnically matched healthy control chromosomes. Three dimensional protein analyses revealed drastic changes in the normal functions of the variant proteins. Furthermore, these variants were designated as “pathogenic” as per guidelines of American College of Medical Genetics 2015. Due to overlapping phenotypes, among the patients, clinical subtyping was not possible. However, whole exome sequencing successfully pinpointed the molecular diagnosis which could be helpful for better management of these patients. Therefore, we recommend that exome sequencing be performed as a first-line molecular diagnostic test in familial cases
