A semi-classical Boltzmann transport model is developed to observe photon-assisted dynamics of induced carriers in the graphene nanoribbons. When the nanoribbons are subject to a multi-frequency Alternating Current (ac) field and superimposed on by static Direct Current (dc) field, an unusual non-linear response of the system shows up at a rather strong drive force. The non-linearity in the photo-current allows for up-conversion necessary for low-frequency oscillators. Regions of positive differential conductivity are observed paving way for graphene to be operated as a small signal amplifier for Terahertz (THz) applications. The fractional photon-assisted phenomenon is also observed when the stark factor r > 1 and the ratio of the n-th harmonic to stark factor takes on half-integer values.

The present study provides the health application at affordable cost. This study such as ethnomedicine keenly represents one of the best avenues in searching new economic plants for medicine.The present investigation was carried out to examine the qualitative phytochemical analysis, antibacterial and anti-oxidant effect of polyherbal drugs namely Shirishadi and Bharangyadi. The hydroethanolic extracts of drugs showed the presence of alkaloid, tannins, flavanoids, phlobatannins, saponins, terpenoids, cardiac glycosides, anthraquinones, proteins, amino acids and carbohydrates particularly reducing sugars. The estimations of total phenolics content in the selected groups was also done spectrophotometrically following the Folin – ciocalteau method and was found to contained 112mg/g & 50.98+ 0.62 of phenolics respectively. Flavonoids were also estimated following the aluminium chloride method and 13.66 + 1.67mg/g of flavonoids was found to present in Bharangyadi compound whereas Shirishadi contains 23.89 + 4.62mg/g. ABTS+ assay shows maximum inhibition of 82.27 ± 2.69 with EC50 462.72 ± 4.56 for Shirishadi and Bharangyadi shows 64.2+ 0.86 percent inhibition with EC50 675.31 + 4.24. Assessment of antimicrobial activity shows that Bharangyadi has more potent antibacterial and anti-fungal effect than Shirishadi. Antibacterial activity was best revealed by Bharangyadi compound against Plesiomonas shigelloides followed by Pseudomonas aeruginosa it showed strong antifungal property with maximum affinity against Candida parapsilosis. Shirishadi compound also showed effective antibacterial and antifungal activities with maximum inhibition zone against Plesiomonas shigelloides and Candida tropicalis.Both the drugs were tested against seven bacterial strains and four fungal strains.

This study analyses the effect of media exposure and perceived bias on performance rating of the Modi government that was elected in 2014 in India. A sample of Coimbatoreans (N = 210) was chosen for the survey. Results showed that media exposure had a positive and direct effect on performance rating, while bias had a significant but negative effect. Such perceived media bias also had an ability to alter the political affiliation of the people, which in turn affected the performance rating, positively. Political participation of the people also exerted a direct effect on public perception about media bias towards the ruling Modi government.

Styrene-divinylbenzene copolymer is a special macroporous strong base anion resin crosslinked with divinylbenzene that is specially selective for hydrophobic anions. It shows good mechanical strength and an excellent resistance to osmotic and thermal shock. The amination reactions were done by chloro dimethyl ether solvent at 45°C. TGA and FTIR techniques were used to investigate the thermo gravimetric analysis and structures of obtained resins, respectively. The exchange capacities of anion exchange resins (X-16) are 312 meq/100g as determined by titration method. Then the structure of PS-DVB resin was investigated by scanning electron microscope (SEM) technique. The SEM images showed that the porous structure of PS-DVB resin was approximately intact after amination reaction.

Studies have shown that alcohol use is a vice that has serious effects on the users. However use of the substance has been found to be highly prevalent among various populations including University students. In order to ascertain this assertion, this study examined the prevalence of alcohol use among the students of Mount Kenya University, Kenya. Data was collected from a population of 258 participants from Mount Kenya University who were between 18-26 years of age. The sample of the study comprised of 126 undergraduate students from the said university. This sample was selected using stratified purposeful sampling method. The instrument that was used for screening alcohol use among the students was the Alcohol Use Disorder Identification Test (AUDIT). Participants who scored 7 or less in AUDIT were considered to have low risk to AUD, hence they were casual and social drinkers whereas, those who scored 8 and above were diagnosed to exhibit alcohol use disorder. The distribution of participants’ gender scores showed that male participants who had AUD were higher at 10.9% as opposed female participants who had AUD at 5.5%. The frequency of participants who scored 7 or less were higher (215, 83.7%) compared to those who scored 8 or above on AUDIT (42, 16.3%). Therefore, the prevalence of alcohol use disorder among the students of Mount Kenya University was 16.3%. Recommendations were made for stakeholders to arrange for strategic therapeutic activities for different groups of students and especially those that are almost graduating from University.

A graph G=(V,E) with n vertices is said to be admitted prime labeling if its vertices can be labeled with distinct positive integers not exceeding n such that the label of each pair of adjacent vertices are relatively prime. Some previous work on prime labeling includes prime labeling of bipartite graphs and ladder graphs. In this work, a new graph called Snow graph which is a union of wheel and star graphs is introduced. A theorem is given to obtain a prime labeling for this graph and an algorithm for prime labeling is given.

Leadership plays a crucial role in the management of international airlines' alliance ground staff operations environment. Leadership that is transformational and proactive can serve to optimize the talents of a diverse and inclusive workforce and have the potential to affect an organization positively. This qualitative study was reinforced with the lens of the transformational leadership theory, as the purpose of this single case study was to explore the role of leadership in a U.S.-based international airline alliance, and their approach to leading ground staff operations, successfully. Managing a diverse workforce is often a challenge, as the aim is to ensure desired and optimal organizational effectiveness and performance, on which organizational sustainability and profitability hinges. The study entailed the collection of data using semistructured interviews in computer-mediated conferencing format with five airline alliance leaders located in the state of Georgia, who held at least 2 years of successful experience in leading a diverse workforce. The analysis using a process of constant comparison and thematic analysis yielded the principal theme of the importance of the proactiveness of leadership, in leveraging a diverse workforce, under the aegis of strategic human resources management, and leadership. A key recommendation is for airline alliance leaders to display astute transformational skills and align diversity, equity, and inclusion policies as a critical corporate human resources strategy. Optimizing employee performance is vital in gaining a competitive advantage in a field where service quality is a key differentiating factor in being superior among equals.
