Abstract. Background: The public health sector has advocated for more innovative, technology-based, suicide prevention education for the community, to improve their ability to detect and respond to suicide risk. Emerging evidence suggests addressing the bystander effect through the Bystander Intervention Model (BIM) in education material may have potential for suicide prevention. Aims: The current study aimed to assess whether BIM-informed tools can lead to improved readiness, confidence and intent in the community to detect and respond to suicide risk in others. Method: A sample of 281 adults recruited from the community participated in a randomized controlled trial comprising a factsheet designed according to the BIM (intervention group) and a standard factsheet about suicide and mental health (control group). Participants' self-reported detecting and responding to suicide risk readiness, confidence, and intent when presented with a suicidal peer was tested pre- and postintervention and compared across time and between groups. Results: The intervention group had significantly higher levels of detecting and responding to suicide risk readiness, confidence, and intent than the control group at postintervention (all p < .001) with moderate-to-large effect sizes. Limitations: The study was limited by a homogenous sample, too low numbers at follow-up to report, and self-report data only. Conclusion: This study demonstrates BIM-informed suicide prevention training may enhance the community's intervention readiness, confidence, and intent better than current standard material. Further testing in this area is recommended. While results were statistically significant, clinical significance requires further exploration.

This book explores important aspects of Markov and hidden Markov processes and the applications of these ideas to various problems in computational biology. It starts from first principles, so that no previous knowledge of probability is necessary. However, the work is rigorous and mathematical, making it useful to engineers and mathematicians, even those not interested in biological applications. A range of exercises is provided, including drills to familiarize the reader with concepts and more advanced problems that require deep thinking about the theory. Biological applications are taken from post-genomic biology, especially genomics and proteomics. The topics examined include standard material such as the Perron–Frobenius theorem, transient and recurrent states, hitting probabilities and hitting times, maximum likelihood estimation, the Viterbi algorithm, and the Baum–Welch algorithm. The book contains discussions of extremely useful topics not usually seen at the basic level, such as ergodicity of Markov processes, Markov Chain Monte Carlo (MCMC), information theory, and large deviation theory for both i.i.d and Markov processes. It also presents state-of-the-art realization theory for hidden Markov models. Among biological applications, it offers an in-depth look at the BLAST (Basic Local Alignment Search Technique) algorithm, including a comprehensive explanation of the underlying theory. Other applications such as profile hidden Markov models are also explored.

Nanocomposites are substances that incorporate nanoparticles (0.5-5% by weight) into a matrix of standard material, which enhances the mechanical strength, toughness including thermal or electrical conductivity and other properties. Nanocomposites are versatile in terms of their applications such as anti-corrosive, healing of bones, sensors, environmental protection, packaging, wastewater treatment, and diagnosis of tumors and other diverse uses. They may be fabricated by blending nanofillers with a polymer to produce a composite. The current trend of processing is by polymerizing monomers. Nanocomposites serve as sustainable solutions to curb global issues. Evaluation is performed on properties such as mechanical, thermal, dispersion, and toxicological. Some marketed products of nanocomposites include In Mat (coating), FiltekZ350 XT by 3M (tooth fillers), chitosan/organic rectorite nanocomposite films (bactericidal activity), graphene oxide/Carboxymethylcellulose (targeted drug delivery of anti-cancer drug doxorubicin), MD1 Flex, Nano Clean MD1, Plactive TM (Antimicrobial nanocomposites) and NovaProTM(Tooth fillers). This article discusses about Nanocomposites–their types, preparation methods, recent research and applications.

Crossflow turbines represent a valuable choice for energy recovery in aqueducts, due to their constructive simplicity and good efficiency under variable head jump conditions. Several experimental and numerical studies concerning the optimal design of crossflow hydraulic turbines have already been proposed, but all of them assume that structural safety is fully compatible with the sought after geometry. We show first, with reference to a specific study case, that the geometry of the most efficient impeller would lead shortly, using blades with a traditional circular profile made with standard material, to their mechanical failure. A methodology for fully coupled fluid dynamic and mechanical optimization of the blade cross-section is then proposed. The methodology assumes a linear variation of the curvature of the blade external surface, along with an iterative use of two-dimensional (2D) computational fluid dynamic (CFD) and 3D structural finite element method (FEM) simulations. The proposed methodology was applied to the design of a power recovery system (PRS) turbine already installed in an operating water transport network and was finally validated with a fully 3D CFD simulation coupled with a 3D FEM structural analysis of the entire impeller.

Background Faecal occult blood testing is an important diagnostic tool for the detection of colorectal cancer. However, it has not been standardized due to the absence of suitable specimens for surveillance. Methods We developed a ready-to-use artificial stool made from rice flour. This new artificial stool homogeneously contains not only human haemoglobin A0 (HbA0) but also glycerol as an internal standard material. After the collection of the artificial stool into a buffer, the haemoglobin concentration in dispersed solution was measured using a method based on the peroxidase like activity of haemoglobin. The glycerol concentration was measured using a commercially available triglyceride measurement kit. Results With regard to the haemoglobin stability, the decrease in the level of human haemoglobin in the artificial stool was <2% when it was stored at −80℃ for four months, −20℃ for two weeks, and 5℃ for two days. The artificial stool was easily collected with the collecting tubes of a commercially available faecal haemoglobin test kit. The weight of the collected artificial stool could be calculated by measuring the concentration of glycerol in the extracting solution of the collected stool sample. The haemoglobin concentrations could be adjusted based on their collection weights. Conclusions The artificial stool has a paste-like consistency and contains both haemoglobin and glycerol homogeneously. Furthermore, the measured haemoglobin concentration could be determined based on the collected stool weight, which was directly related to the glycerol concentration. These features make it a useful material for the surveillance of faecal occult blood testing.

Abstract A method for analyzing fensulfothion was tested by 10 collaborators. Formulations were dissolved, or extracted from inerts, in methanol. Benzophenone was used as an internal standard. The solution was diromatographed on a Partisil-10 ODS-2, or equivalent, reverse phase column, and detected at 230 nm. A mobile phase of methanol-water-phosphoric acid was used. The ratio of fensulfothion peak height to benzophenone peak height was calculated from the UV response and compared to the standard material for quantitation. A 15% granular formulation was analyzed as a matched pair. The results of one collaborator were outliers by the Dixon test. The coefficient of variation for the granular formulation was 1.6%. A matched pair of 63% spray concentrate samples was analyzed by 10 collaborators. The difference in results was an outlier for one collaborator; the coefficient of variation for the other collaborators was 1.5%. The method has been adopted official first action.

Uterine Scar

Background: Cesarean section uterine scar dehiscence (CSD) is a rare but notable complication of Lower segment cesarean section (LSCS) surgery. The cause for a uterine scar dehiscence is based on the etiology behind the uterine scar defect or any event that would predispose the cesarean scar to dehisce. Globally accepted option for assessing the CS scar is transvaginal ultrasonography of the non-pregnant uterus. Objective: To determine the diagnostic accuracy of lower uterine segment scar thickness≤1.6mm in the prediction of scar dehiscence in patients with previous one LSCS who are undergoing repeat LSCS after trial of labour taking intraoperative findings as gold standard. Material and methods: This cross sectional study was conducted in Services Hospital, Lahore for 6 months. The Non probability consecutive sampling technique was used to include women with previous one LSCS at 36-38 weeks were asked to get their TVS done for scar thickness. Women with scar thickness≤1.6mm and scar thickness>1.6mm were identified. Their intraoperative findings of scar dehiscence were confirmed. All the data was entered and analyzed on SPSS version 20. Results: The mean age of patients was 29.87±6.07 years. The emergency LSCS was done in 599(49.1%) patients and elective LSCS was done in 621(50.9%) patients. The sensitivity, specificity & diagnostic accuracy of TVS was 98.31%, 99.05% & 98.69% respectively. Conclusion: According to our study results the TVS for uterine scar is a very useful and effective tool in the prediction of scar dehiscence in patients with previous one LSCS taking intraoperative findings as gold standard.
