Abstract

Social representations in health have several consequences in influencing attitudes and behaviours, and are important factors in concepts such as health literacy and stigma. We examined how the Indian print news media portray psychiatric genomics using a mixed-method approach of content analysis. The sanguine picture of the optimism portrayed might represent an unjustified hyping in the worst cases. There was a gap between optimism showcased in the ‘predicted quality of life’ and the voices heard in the newspapers to corroborate the same. The prevalence of anti-stigmatizing themes hinted towards a progressive approach being disseminated to the readers. There is a visible interest in personalized medicine. The curve of psychiatric genomics leans towards precision medicine in the articles based on the themes analysed and ‘pharmacogenomic testing’ being mentioned. However, whether or not it will be marred by contrasting research studies and artistic depiction in movies is something to look forward to. It is reasonable to assume that a certain amount of skepticism and apprehension would be a possible reaction for those who read contradictory views about the field. This paves the way for future studies to understand public perception on this topic.

Abstract

A posterior urethral valve is an obstructing membrane in the posterior part of male urethra leading to renal failure and death occurring in 1:5000 to 8000 male live births. The incidence of intrauterine deaths related to posterior urethral valve is under reported. The cause for the occurrence is unclear. Posterior Urethral Valve syndrome is a syndrome of obstructive uropathy resulting in hypertrophy of bladder, ureters and dysplasia of the kidneys. Prenatal ultrasonography is a gold standard diagnostic tool. The fetal autopsy conducted over the case presented here demonstrates all the classical findings of the obstructive uropathy (renal dysplasia, hydronephrosis, bladder hypertrophy, hydro ureters). The case reiterates the importance of prenatal ultrasonography and meticulous fetal autopsy to determine the cause of intra uterine fetal death.

Abstract

There have been periodic discussions on the state of Indian Science and Technology (S&T) journals. Several reasons have been attributed for the low quality of these journals. Different authors at different points in time have articulated steps and approaches to strengthen the Indian S&T journals. One of the long-held contentions has been that the best of Indian scientists should choose Indian journals over foreign ones to publish their best works. This article traces key discussions of the last 90 years and revisits some of the contentions.

Keywords

Indian journals, journal quality, research journals, science and technology journals.

Abstract

The Next Generation Wireless Networks (NGWN) are envisioned to offer abundant services to its users. Quality of Service (QoS) needs varies amongst users as per application requirements and user class. Hence both from the service provider as well as user point of view user differentiation is an important aspect in NGWN. Optimal revenue generation along with guaranteeing the agreed upon QoS to the users’ is a challenging problem for the network service providers. With more number of users in the system more revenue will be generated, but guaranteeing the agreed upon QoS becomes difficult. Call Admission Control (CAC) directly controls the number of users in the system and hence must be carefully designed. This paper proposes a differential access model for CAC mechanism in NGWN based on the users’ QoS needs. The model is based on allocating more number of channels to high priority users as compared to low priority users. The simulation results for call blocking probability of different user classes and the system are presented.

Keywords

Call Admission Control, Differential Access Model, Next Generation Wireless Networks, Quality of Service, User Class.

Abstract

Nature, an interdisciplinary scientific journal, is one of the world's most reputed journals. It has been ranked the world's most cited scientific journal by the Science Edition of 2014 Journal Citation Reports, and is widely regarded as one of the few remaining academic journals that publish original research across a wide range of scientific fields. Academic Ranking of World Universities considers papers specifically published in Nature as a criterion for its world rankings. In 2009, Nature was named as the 'journal of the century' by the Bio-Medical and Life Sciences Division (DBIO) of the Special Libraries Association (SLA), USA. Needless to say, having a paper published in Nature is considered prestigious. The present study aims to show India's output in this journal.

Abstract

Today, electronic journals (e-journals) reign supreme in the scholarly communication landscape. In the print journals era gone by, libraries owned the print journals subscribed by them. Consequently, it is still possible to retrieve an article from the journal held by a library, however distantly located. This is irrespective of a print journal having been discontinued by the publisher or closure of the journal publishing house itself.

Abstract

Globally, the use of English language has been continuously increasing and English is reported to be the most widely learned second language. In scholarly communication too, English has become the preferred language although it is well known that many scientific terminologies and words are derived from Latin and Greek. It has been reported that 'science reached the end of its Latin when in 2012 International Code of Botanical Nomenclature declared as no longer obligatory that the Linnaean binomial classification, but also the description of candidates for new species, be in Latin'.

Abstract

Madhu has given a detailed account of a video journal and highlighted the need for developing a similar medium in India. When the Journal of Visualized Experiments (JoVE) was launched about a decade ago, there was some skepticism about it. Today, the video journal is not only an accepted format, but many longstanding as well as new journals include videos as supplementary content to the articles. However, the video journal is only one of the many formats of scholarly journals that have emerged since the turn of the 21st century.

Abstract

Studies on gender disparity in science, technology, engineering and medicine (STEM) are gathering considerable attention across the globe. Almost in every field of STEM a male predominance can be noticed. Gender analysis in popular science writing has not been studied so far. The present study was carried out to analyse the gender dimension in popular science writing in India using Science Reporter, India’s leading popular science magazine. All the issues of the monthly magazine published between 2010 and 2020 were analysed. The study supports the hypothesis that gender disparity is evident even in popular science writing. The number of articles contributed by women is considerably lower than men. Women tend to show more interest in collaboration in popular science writing

Keywords

Gender gap, popular science, science communication, Science Reporter.

Abstract

Polylactic acid (PLA), also known as polylactide, is a thermoplastic polyester that is commonly used in Fused deposition modeling (FDM) 3D printing and is considered one of the world's far more widely used bio-plastics. PLA is considered biodegradable and environmentally beneficial, unlike petrochemical-based polymers. This is a low-cost product that could be used in a variety of applications, including food packaging, tissue scaffolding, and biomedical devices. This proposed study is primarily concerned with an in-depth investigation of polylactic acid's mechanical strength and its optimization. The L-9 orthogonal array is adopted by utilizing the Taguchi design of experiments, with input characteristics such as Printing speed, Infill density, and Layer height for the fabrication of nine different sets of flexural and compressive specimens as per ASTM standards using FDM. The responses such as compressive strength and flexural strength are optimized using Taguchi Analysis – S/N Ratios and ANOVA. Similarly, this research reveals a statistical link between input elements and responses. According to the current study, the ideal parameter levels for Flexural and Compression strengths have been found and confirmation Tests have also been conducted according to the optimized process parameter levels as obtained in the Taguchi analysis.
