Caffeine is the most popular psychoactive drug consumed in the world for improving alertness and enhancing wakefulness. However, caffeine consumption beyond limits can result in lot of physiological complications in human beings. In this work, we report a novel detection scheme for caffeine integrating nanohybrid membranes of reduced graphene oxide (rGO) in chitosan modified silica sol gel (rGO: chitosan: silica sol gel) with fiber optic surface plasmon resonance. The chemically synthesized nanohybrid membrane forming the sensing route has been dip coated over silver coated unclad central portion of an optical fiber...

Exposure to radiofrequency (RF) radiation was classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO in 2011. The exposure pattern is changing due to the rapid development of technology. Outdoor RF radiation level was measured during five tours in Stockholm Old Town in April, 2016 using the EME Spy 200 exposimeter with 20 predefined frequencies. The results were based on 10,437 samples in total. The mean level of the total RF radiation was 4,293 µW/m(2) (0...

Building on developments in machine learning and prior work in the science of judicial prediction, we construct a model designed to predict the behavior of the Supreme Court of the United States in a generalized, out-of-sample context. To do so, we develop a time-evolving random forest classifier that leverages unique feature engineering to predict more than 240,000 justice votes and 28,000 cases outcomes over nearly two centuries (1816-2015). Using only data available prior to decision, our model outperforms null (baseline) models at both the justice and case level under both parametric and non-parametric tests...

In the recent court case of In Re Guardianship of Hailu, the Nevada Supreme Court cast doubt on the acceptability of the American Academy of Neurology's guidelines as a medical standard for determining brain death. The Uniform Determination of Death Act, which has been adopted in every state, requires that brain death diagnoses be made in accordance with accepted medical standards. The Court expressed concern that the guidelines fail to ensure that there is an irreversible cessation of all functions of a person's entire brain, which is a component of the Act's definition of death...

The 2015 judgment of the Namibia Supreme Court in Government of the Republic of Namibia v LM and Others set an important precedent on informed consent in a case involving the coercive sterilisation of HIV-positive women. This article analyses the reasoning and factual narratives of the judgment by applying Neil Manson and Onora O'Neill's approach to informed consent as a communicative process. This is done in an effort to understand the practical import of the judgment in the particular context of resource constrained public healthcare facilities through which many women in southern Africa access reproductive healthcare...

BACKGROUND: In 2012, the Supreme Court of Canada (SCC) ruled that people living with HIV (PLWH) could face criminal charges if they did not disclose their serostatus before sex posing a "realistic possibility" of HIV transmission. Condom-protected vaginal sex with a low (i.e., <1500copies/mL) HIV viral load (VL) incurs no duty to disclose. Awareness and understanding of this ruling remain uncharacterized, particularly among marginalized PLWH. METHODS: We used data from ACCESS, a community-recruited cohort of PLWH who use illicit drugs in Vancouver...

Tissue growth in most fishes occurs by muscular hyperplasia and hypertrophy, which are influenced by different regulatory factors, such as myostatin. The current study evaluated the influence of cultivation in hapas and earthen ponds on the diameter of white muscle fibers and on the myostatin (MSTN-1) gene in GIFT and Supreme varieties of tilapia. Fish of both varieties were reared for 204 days and then divided into four developmental stages. White muscle samples, corresponding to 100 fibers per slide, were collected from the middle region of fish of each variety and cultivation system, and were measured and divided into two classes representing hyperplasia and hypertrophy...

BACKGROUND: The use of supraglottic airways has been recommended in combat trauma airway management. To ensure an adequate airway management on the battlefield, suitable training concepts are sought to efficiently teach as many soldiers as possible. Our aim was to compare three approaches of teaching laypersons in the handling of supraglottic airways in a mannequin model. METHODS: In this prospective randomized blinded study, 285 military service men without any medical background were divided into three groups and trained in the use of the Laryngeal Mask Airway Supreme (LMA) and the Laryngeal Tube Disposable (LT-D)...

Newer second generation supraglottic airway devices may perform differently in vivo due to material and design modifications. We compared performance characteristics of the Ambu® AuraGain™ and LMA Supreme™ Second Seal™ in 100 spontaneously breathing anaesthetised patients in this randomised controlled study. We studied oropharyngeal leak pressures (OLP) (primary outcome) and secondarily, ease of insertion, success rates, haemodynamic response, time to insertion, and complications of usage. We found no significant difference in OLP between the AuraGain versus the LMA Supreme, mean (standard deviation, SD) 24...

Fifty-two countries have abolished all physical punishment of children, yet Canada has retained its criminal defense to 'reasonable' corrective force. In 2004, Canada's Supreme Court attempted to set limits on punitive acts that can be considered reasonable under the law. In the present study, we examined the validity of these limits. If the court's limits provide adequate protection to children, most substantiated child maltreatment cases should exceed those limits. We operationalized each limit and applied it to a provincially representative sample of substantiated child physical maltreatment cases...
