Effect of ocean circulation and chlorophyll-a concentration on yellowfin tuna catch rates in Sri Lankan logline fishery
Authors: Maddumage U. S. , Rajapaksha J. , Gunatilake J.
Published: September 2023

Sri Lanka has access to fishery resources in the Indian Ocean due to its location. While traditional fishing methods are still used in the Sri Lankan fishery industry, modern technologies such as remote sensing and GIS are employed to determine spatiotemporal distribution of tuna fish resources in the offshore fishery industry. However, due to uncertain catch rates, Sri Lankan fishers report low catch per unit effort, leading to increased fishing duration to meet targeted catch. Potential fishing areas can be identified based on oceanographic conditions to reduce search time and improve efficiency, particularly for highly migratory species like yellowfin tuna. Therefore, this study is focused on identifying the impact of subsurface ocean currents and chlorophyll-a concentration on yellowfin tuna aggregations. The study analysed fishery and oceanographic data from January 2018 to December 2019 within a latitudinal range of 0°N to 20°N and a longitudinal range of 70°E to 90°E. The data were gridded at a resolution of 0.25 degrees and then matched for analysis. The generalized additive model (GAM) and the empirical cumulative distribution function (ECDF) were applied to identify the nature of relationships between CPUE and the oceanographic conditions. The results showed high tuna aggregations occurred in chlorophyll-a concentration between 0.3– 0.4 mg/m3 and current speed less than 0.4 m/s at a depth of 60 – 75 m of Sri Lankan longliners. Yellowfin tuna fishable aggregations were available throughout the year, although the spatial distribution of yellowfin tuna varied depending on the prevailing oceanographic conditions. Thus, searching for fishing locations based on oceanographic factors is essential for successful fishing operations. Hence, tuna harvest can be enhanced by maintaining fishing areas and the longline depth according to the oceanographic factors.

GATA3 is a transcription factor involved in embryogenesis of multiple human tissues and in maintaining cell differentiation and tissue homeostasis in the adult organism. GATA3 is also involved in carcinogenesis and regarded as a sensitive marker for urothelial and breast carcinomas, albeit expression in carcinomas of non-breast/urothelial origin has been frequently reported. We sought to examine the extent and intensity of GATA3 expression in various carcinomas, mainly lung, urothelial, and breast and various other primary sites. Patients with breast carcinoma (N=40), carcinoma of the urinary bladder/renal pelvis (N=40), lung carcinoma (N=110) and various other origins (N=45) were included in the study. One hundred and sixty-five patients had a primary tumor diagnosis, and 70 cases had a metastatic tumor diagnosis. Our results showed that GATA3 expression was significantly more common in carcinomas of the breast, urinary bladder and renal pelvis compared to all other origins. All primary and 93% of metastatic urinary bladder carcinomas and 94% of the primary and 80% of metastatic breast carcinomas expressed GATA3. Expression was lower in non-urothelial histology of urinary primaries and in triple negative breast carcinomas. Focal staining, mostly faint, was seen in 5.6% of the primary lung adenocarcinomas and 35% of the primary lung squamous cell carcinomas. More extensive and intense staining was seen in 3.7% of the primary lung adenocarcinomas and 12% of the primary lung squamous cell carcinomas. Expression, mostly focal was also seen in 30% of the metastatic lung carcinomas. Finally, high expression was seen in 12.5% of the other tumors (one metastatic pancreatic carcinoma, one metastatic salivary gland adenocarcinoma NOS, one metastatic squamous cell carcinoma of the skin, one primary uterine cervix serous carcinoma, and one squamous cell carcinoma of the head and neck) and focal expression was present in another 22% of them. No ideal cut-off for positivity for GATA3 staining could be identified. In conclusion our study shows that GATA3 staining has two caveats in its use: the first is that non classical histologies of urothelial carcinomas and TNBC may be negative for the marker and secondly carcinomas of various origins may show (although rarely) intense positivity
Sleep-disordered breathing and heart failure: a vicious cycle of cardiovascular risk
Authors: Cacciapuoti Fulvio , D'Onofrio Antonio , Tarquinio Luca Gaetano , Capone Valentina , Mauro Ciro , Marfella Raffaele , Cacciapuoti Federico
Published: September 2023

Sleep-disordered breathing (SDB) represents an important cardiovascular risk factor that is still often underestimated and not always optimally treated. Such breathing disorders can induce several harmful effects on the heart, also favoring the development of arrhythmias, ischemic heart disease, and left ventricular remodeling. Obstructive sleep apnea syndrome (OSA) is more frequent in heart failure patients than in the general population, promoting the worsening of left ventricular dysfunction. Both sleep apnea and heart failure have common clinical manifestations but also similar neurohormonal characteristics, both contributing to the development and progression of heart failure and resulting in increased mortality. The pathophysiological mechanisms underlying left ventricular dysfunction associated with SDB will be analyzed, and the potential therapeutic effects of gliflozins on OSA in heart failure patients will be discussed.

Authors: Biese Kevin , Winans Madeline , Rudek Grace , Hernandez Mayrena I. , Cadmus-Bertram Lisa , Andreae Susan J. , Brooks M. Alison , McGuine Timothy A. , Bell David R.
Published: September 2023

Context

As youth sport participation grows, athletic trainers (ATs) continue to be important health care providers in managing growth-related injuries.

Objective

To examine secondary school ATs' reported knowledge on diagnosing and treating growth-related injuries and reported confidence for determining growth status and to report methods secondary school ATs use to determine patient growth status.

Design

Cross-sectional.

Setting

An online questionnaire was distributed to secondary school ATs in the United States. Data collection occurred in the summer of 2021 over a 6-week period.

Patients or Other Participants

A total of 430 secondary school ATs (highest degree earned: master's degree = 66%).

Main Outcome Measures

The questionnaire contained secondary school ATs' confidence in determining if an athlete was going through a growth spurt, level of knowledge on diagnosing and treating growth-related injuries, methods secondary school ATs use to determine growth status in their athletes, and demographics.

Results

Most secondary school ATs believed that growth spurts affected sport-related injury risk (88%); however, only 37% of secondary school ATs were fairly or completely confident in their ability to determine if an athlete was going through a growth spurt. For those 37% of secondary school ATs, 89% of them used history or observation over time, but no formal method, for determining growth status of their patients. Patient self-assessed Tanner stages (32%) and clinical evaluation of Tanner stages (28%) were the next most used methods for assessing growth.

Conclusions

In accord with Domain I of athletic training, secondary school ATs could benefit from improved knowledge on how to measure and manage growth in their patient population. To aid education in this area, future researchers should focus on assessing barriers secondary school ATs face in implementing methods for measuring growth and exploring secondary school ATs' knowledge levels on risk management programs for youth athletes going through growth spurts.

Published: September 2023

Context

Athletic trainers have expressed a lack of knowledge and a desire to learn more about the issues impacting lesbian, gay, bisexual, transgender, queer/questioning, pansexual, intersex, asexual/aromantic/agender, two-spirit, and additional community/identity (LGBTQPIA+) patients, yet little is known about how students are prepared.

Objective

The purpose of this study was to explore educational experiences relative to LGBTQPIA+ patient care in Commission on Accreditation of Athletic Training Education–accredited, master's-level professional athletic training programs.

Design

Cross-sectional study.

Setting

Web-based survey.

Participants

Students (N = 333) who were currently enrolled in the last 1 to 2 semesters of their respective programs or had recently graduated from a master's-level professional athletic training program within the last year.

Main Outcome Measure(s)

The survey asked participants to characterize and evaluate the effectiveness of their learning experiences, then rank their confidence in addressing the needs of LGBTQPIA+ patients. We used additional open-ended responses to characterize effective instructional strategies. Data were analyzed using statistics of central tendency and open-ended responses were inductively coded.

Results

Participants reported that their learning experiences about LGBTQPIA+ patient needs were moderately effective for formal (38.2%), informal (42.2%), and clinical education (34.0%). Among the areas where participants reported wishing they had learned more were gender incongruence or dysphoria (39.6%), gender-affirming care (43.5%), and providing inclusive health care forms and documentation (38.4%). Participants reported about 15 ± 37 hours (range, 0–500 hours) of time dedicated to LGBTQPIA+ patient issues, although only 23.2% indicated that this was enough time. Participants indicated that they were quite confident in addressing the needs of LGBTQPIA+ patients (mode = 3 [quite confident], 33.0%); however, 53.7% of participants were only somewhat, slightly, or not at all confident. In the open-ended responses, participants indicated that informal and clinical education experiences providing authentic interactions with LGBTQPIA+ patients were most meaningful.

Conclusions

Professional athletic training programs should incorporate more educational experiences to better prepare students to meet the health care needs of LGBTQPIA+ patients. Participants in our study additionally indicated a strong desire to learn more about equitable patient care.

Authors: Soni Bhanushree , Jayaseelan Venkatachalam , Kattimani Shivanand , Rengaraj Sasirekha , Arikrishnan Kalaiselvy , Veerasetty Naveenkumar
Published: September 2023

Background:

Gestational diabetes mellitus (GDM) is associated with an increased risk of mental health disorders among pregnant women. Poor mental health can negatively impact glycemic control in women with GDM, leading to adverse outcomes for both the mother and the baby.

Aim:

To determine the prevalence of common mental disorder (CMD) in women with GDM and its association with poor glycemic control. Additionally, to explore the reasons and coping strategies for CMD in women with GDM.

Methods:

A sequential explanatory mixed-method study was conducted among 351 women with GDM visiting a tertiary care hospital. The prevalence of CMD was assessed using Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Perceived Stress Scale (PSS). Glycemic control was determined based on two-hour postprandial blood glucose levels. In-depth interviews were conducted with six women who screened positive for CMD and had poor glycemic control. Data were analyzed using SPSS v23 and stats v12. Chi-square test and Poisson regression were performed, and adjusted prevalence ratios (aPRs) were reported.

Results:

The prevalence of CMD was found to be 19.08% (95% CI: 15.32%-23.52%), with 18.2% (95% CI: 14.5%-22.6%) anxiety symptoms 8.3% (95% CI: 5.8%-11.6%) depressive symptoms and stress each. CMD was significantly related to poor glycemic control (aPR: 1.58; 95% CI: 1.23-2.03; P value <0.001). The qualitative analysis revealed individual, family, health, and facility factors influencing mental health and glycemic control.

Conclusion:

Common mental health disorders are prevalent in women with GDM. It has a negative association with glycemic control. Implementing a routine screening program in the ANC clinic can aid in early identification and prompt management of the CMD and its associated complications.
Residual experiential symptoms mediate the effect of expressive symptoms over the social functioning in remitted schizophrenia
Authors: Moses Dinesh G. , Palaniappan Pradeep , Ponraj Pratap Chander
Published: September 2023

Context:

Impairment in social functioning had been consistently found in remitted schizophrenia; yet, predictors of social dysfunction had been hardly explored and intervention trials had rarely included remitted schizophrenia.

Methods:

60 subjects with schizophrenia (diagnosed based on DSM5), currently in remission (SAPS and SANS global rating ≤2, for a minimum period of 12 weeks) and 46 age and gender-matched healthy controls were recruited after obtaining informed consent. The socio-demographic details, illness characteristics, depressive symptoms, positive and negative symptoms [using Scale for assessment of positive symptoms (SAPS), and scale for assessment of negative symptoms (SANS)] were assessed. The Theory of Mind (ToM) score was derived from the ToM tasks of a culturally validated tool, Social Cognition Rating Tools in Indian Setting. The social functioning was assessed using Groningen social disabilities schedule II (GSDSSII).

Results:

The mean SAPS summary and SANS summary scores were 3.01 ± 2.99 and 4.32 ± 2.94, respectively. The social functioning was significantly impaired in remitted schizophrenia when compared to healthy controls. In the hierarchical regression, experiential dimension (β=1.941, t = 6.097, P < 0.001), followed by expressive dimension predicted social functioning (explained 70.5% of variance) after controlling for confounders. On mediation analysis, the effect of expressive dimension over the social functioning was significantly mediated by experiential dimension (E = 1.1821, Boot SE = 0.2895, C.I: 0.6934 to 1.7862)

Conclusion:

The experiential dimension mediates the effect of expressive dimension over the social dysfunction in remitted schizophrenia. Future studies should focus on targeting the experiential dimension and thereby social functioning.
Geometric triangulations and the Teichmüller TQFT volume conjecture for twist knots
Authors: Ben Aribi Fathi , Guéritaud François , Piguet-Nakazawa Eiichi
Published: September 2023

We construct a new infinite family of ideal triangulations and H–triangulations for the complements of twist knots, using a method originating from Thurston. These triangulations provide a new upper bound for the Matveev complexity of twist knot complements.

We then prove that these ideal triangulations are geometric. The proof uses techniques of Futer and the second author, which consist in studying the volume functional on the polyhedron of angle structures.

Finally, we use these triangulations to compute explicitly the partition function of the Teichmüller TQFT and to prove the associated volume conjecture for all twist knots, using the saddle point method.

Published: September 2023

The study aimed at examining the practice of employing authentic instruction and identifying predictors in upper primary mathematics lessons in Bahir Dar Special Administrative Zone, Amhara National Regional State, Ethiopia. The study employed a mixed-methods exploratory sequential design. Data were collected through observation, interviews, and questionnaires from upper primary school mathematics teachers. The authentic learning questionnaire was pilot tested, and the internal consistency was found to be.766. Qualitative data from interviews and observations were analyzed using content analysis while quantitative data from observations were analyzed using a one-sample t-test; on the other hand, quantitative data from questionnaires were analyzed using a one-sample t-test and hierarchical multiple regression. The results revealed that there was lack of effort to practice authentic instruction; the instruction did not situate learning in a real-life setting. The dimension level analyses showed that all ten dimensions of the authentic instructional model were poorly practiced. The findings also revealed that among several challenges, four factors appeared to be significant predictors: lack of understanding and skills in authentic learning, less suitability of mathematics curriculum, inflexible and short schedule and period, and large class size. The researchers recommended that responsible government bodies and teacher training institutions exert greater effort to change the situation. Training should be given to teachers to improve their understanding and skills, and the curriculum should be suited for authentic learning.

Ansiedad-Estado y rendimiento académico en universitarios de enfermería.
Authors: Sánchez-Domínguez Juan Pablo
Published: September 2023

La presente investigación tuvo por objetivo determinar la relación entre la Ansiedad-Estado (A-E) y el Rendimiento Académico (RA) en una población de 262 estudiantes de enfermería de una institución pública del sureste mexicano. Para Spielberger (1989), la Ansiedad-Estado es una condición emocional transitoria del ser humano caracterizada por sentimientos de tensión percibidos. Este factor en niveles moderados eventualmente favorece el Rendimiento Académico; sin embargo, en índices elevados lo obstaculiza. Para determinar la A-E se utilizó el Cuestionario de Ansiedad Estado-Rasgo de Spielberger & Díaz (2010) y para establecer el RA se analizaron las calificaciones escolares. Del análisis correlacional se observa una relación positiva y estadísticamente significativa muy baja entre la A-E y el RA (.134; p < 0,05).

Published: September 2023

En la actualidad, la delincuencia ha afectado a las distintas localidades del país. Este trabajo tiene como objetivo analizar el crecimiento de la delincuencia juvenil en el sector del By Pass de la ciudad de Babahoyo. Se considera que la delincuencia juvenil ocurre, por lo general, en las zonas marginales del país, aunque esto no siempre es así. Una de las mayores razones para que esto ocurra es la flexibilidad que tiene la ley en el Ecuador para juzgar a los menores de edad; lo que significa, que si no hay medidas correctivas a nivel legal esto seguirá en crecimiento. El estilo de vida que llevan los adolescentes también es un agravante, se vuelve un patrón a seguir en las familias. En este análisis se sustenta este trabajo.

In recent years, the world's need for fossil energy such as oil and gas will increase. Meanwhile, fossil energy reserves are decreasing. This is also due to the high number of motorized vehicles. With the growth of motorized vehicles as a mode of transportation and limited fossil fuels, it is necessary to develop renewable energy as an alternative energy. This is a step to reduce the use of fossil fuels. . Ethanol is an alternative fuel source derived from plants or vegetable sources. The high octane contained in ethanol can be used as a fuel mixture or as the fuel itself. This research was carried out experimentally to determine the effect of using ethanol on the power, torque, and efficiency of the engine. In carrying out this research the first steps required are fuel, ethanol, piston variations and a tool to obtain data, namely the Dynotest. The engine will observe changes in the aspects of power, torque and efficiency by using the addition of ethanol to pertalite and piston changes. The percentages used are 25%, 30%, 35%, 40%.

Solar based E-Uniform gives better protection to the soldiers who are working in extreme weather conditions. Solar Panels are used to power up the internal circuitry of the E-uniform. A 12 V DC lead acid rechargeable battery is used for storing the energy. We are using conventional battery charging unit also for giving supply to the circuitry. AT89S52 micro controller is the heart of the circuit as it controls all the functions. A voltage sampler is interfaced with the system using ADC 0808 to get the voltage generated from battery as a display on a 16X2 LCD. The project is operated in summer mode and winter mode. By selecting the mode of operation, we are operating the H-Bridge IC such that it can drive body heater/cooler. The heater/cooler in turn will help us to provide chilling or warming effect inside the uniform which helps the soldier to bear to any kind of external environment. The metal sensor will detect the metal like bomb and intimate the soldier with a buzzer indication. The GSM is interfaced with the microcontroller and GPS is also interfaced such that the tracking of the entire soldier is observed. And the location is messaged to the particular concern person /dept. This Uniform will make the soldier to work in any kind of environment.

The greater usage of fossil fuels and increasedcarbon emissions, which hasten their rapid depletion, inducesconsumers to switch to renewable energy. Traditional irrigationtechniques may be expensive or environmentally harmful. Inlight of this, conversion to renewable energy sources, like solarenergy, can resolve this problem. Solar energy is widely usedin a wide range of applications since it is user-friendly andenvironmentally friendly. Yet, many rural areas of India continueto use conventional irrigation systems, such as diesel pumps,for irrigation. They are neither economical nor environmentally favourable. It releases a significant amount of hazardous gases,such as carbon dioxide. Farmers can operate a water pumpeffectively and sustainably by adopting a solar photovoltaic-based water pumping system. With the use of moisture sensors,scientific irrigation methodology is implemented, makingirrigation more efficient. In comparison to current technologies,this system is reliable, economical, and capable of increasingagricultural productivity levels. The requirement for labour is also decreased by irrigation automation and wireless control.In this, a permanent magnet DC (PMDC) motor-drive powersthe water pump. Outside in the field plains, moisture sensorsare being installed to keep track of the wetness in the soil. Themicrocontroller uses the information from the sensors to regulatethe pump’s operation.

Due to the day-to-day innovations and development in construction field, the use of natural aggregates is increased tremendously and at the same time, the production of solid wastes from the demolitions of constructions is also quite high. Because of these reasons the reuse of demolished constructional wastes like Jhama Brick and Marble powder came into the picture to reduce the solid waste and to reduce the scarcity of natural aggregates for making concrete. Studies show that about 20-30% of material prepared in the marble manufacturing plants are transforming into waste. This waste material should have to be reused in order to deal with the limited resource of natural aggregate and to reduce the construction wastes. This present study is to understand the behavior and performance of Jhama Brick and Marble powder waste in concrete. The waste Jhama Brick are used to partially replace coarse aggregate by 0%, 10%, 15%, 20% and 25% . Marble powder is also used partial replace fine aggregate by 0%, 8%, 12%, 16% and 20%. M25 grade of concrete was designed and tested. The mix design for different types of mixes were prepared by replacing the coarse and fine aggregates at different percentages of Jhama Brick and Marble powder. Experimental investigations like workability, Compressive strength test, split tensile strength test, Flexural strength test for different concrete mixes with different percentages of waste crushed after 7, 14 and 28-days curing period has done. It has been observed that the workability increases with increase in the percentage of replacement of Jhama Brick and Marble powder increases. The strength of concrete also increases with the Jhama Brick and Marble powder aggregate up to 20% percentage.

Recent advances in innovation have made ordinary people's lives richer, simpler, and easier. Many people suffer from vision impairment, which causes many difficulties in their daily work, according to World Health Organization (WHO) statistics. Our goal is to develop a framework that is unobtrusive, safe, portable, and versatile in order to assist blind people in their daily lives. It intends to develop an effective system for assisting the visually impaired with obstacle detection and scene classification. The Raspberry-Pi 3B+ and a camera module are used in the proposed method. It photographs the scene and then preprocesses the images with Viola-Jones and Yolov5 object detection algorithms. The aforementioned techniques are used to detect people and objects. We also used a sound system that speaks when an object or person is detected. The presented study implements simple computations and detects obstacles with high efficiency. Unlike other frameworks, this framework is lightweight and easy to transport

There have been many reports of accidents caused by the use of damaged and worn tires, and these accidents are more common on highways and during the rainy season. Although this is a common problem, many people cannot distinguish good tires from worn ones, increasing the risk of ending up with good tires on the road. A few years ago, the main technology for checking tire size was manual inspection. An important method is to determine the grade of the tread pattern bed by checking the depth and the shoulder pattern bed. Tires are one of the most important parts of a vehicle as they actively support driving. However, they often disagree when it comes to proper inspection and maintenance. Most of the time, the general public apparently does not care about their tires. Many will experience tooth wear and flank damage, and failure to follow up on these problems will cause long-term damage. However, this method is too expensive to use in a family car. This article presents a model used as a running image that can distinguish broken tires from rubbing tires. The model is based on the image displayed outside the user-supplied tire and determines its status after comparing it with the model data using the deep learning algorithm ResNet50. This model is made to remind you that it can be used in addition to equipment suitable for use in real life applications. With regulation by regulatory agencies, tire accidents can be reduced and damage to people and property on public roads can be prevented.

Published: September 2023

The unique properties of conducting polymers not only provide great scope for their applications but also have led to the development of new models to explain their observed properties. Polyaniline has been the oldest among all the conducting polymers. Polyaniline has rapidly become the subject of considerable interest for physicists, chemists and material scientists. In this paper we have carried out the X-Ray Diffractional analysis of Polyaniline thin films doped with different concentrations (15% & 30%) of the dopants like Potassium Bromide and Picric Acid. The films has been prepared by using Vacuum Evaporation Technique and then characterized for XRD studies by using the X-Ray Diffractometer. The XRD studies reveals that the crystallinity of the doped polyaniline thin films has been increased with the increased doping concentration of the above said dopants which ensures its applications in the optoelectronic device technology.
Petrogenesis of Amphibolite/Hornblendite Dikes in Qala-Diza Area, Iraqi Kurdistan Region
Authors: Petros Jolyana , Karo Nihad
Published: September 2023

The amphibolite and hornblendite dikes occur as part of the igneous complexes of Bulfat Ophiolite within the Zagros Suture Zone, NE Iraq. The igneous complex is part of the upper allochthonous ophiolite terrane within the second unit of the Penjween-Walash Subzone. This article discusses the petrogenetic characteristics and tectonic setting of the amphibolite rocks based on their petrography, mineral chemistry, and whole-rock geochemistry. Petrographically, both banded and massive amphibolites reveal that the main mineral constituents are amphibole and plagioclase with accessory clinopyroxene, opaques, sphene, apatite, rutile, zircon, sericite, epidote and chlorite; meanwhile the hornblendites consist of >90% amphibole with minor amounts of pyroxene, opaques, plagioclase, titanite, quartz, apatite, zircon, and chlorite. The amphibolites are divided into two types, banded (foliated) and massive, (non-foliated). The dominat textures of amphibolites are porphyroblastic, granoblastic, poikiloblastic, nematoblastic, and blasto-ophitic; meanwhile those of hornblendites are equigranular, poikilitic, cataclastic, and intergranular. The electron microprobe analysis (EPMA) showed that the amphiboles of the banded amphibolite range between tschermakite, magnesio-hornblende and pargasite; and those of the massive amphibolites range between magnesio-hornblende and actinolite; meanwhile those of hornblendites are dominantly tschermakite with minor magnesio-hornblende and pargasite. The plagioclase of the banded amphibolites is mainly oligoclase and andesine; and those of the massive amphibolites are mostly anorthite. Chemical classification diagrams indicated that the studied rocks are had low alkalies (Na2O+K2O), tholeiitic, ultrabasic to basic, alkaline to subalkaline and divided between foidite, picrobasalt and basalt. Various tectonic discriminating diagrams showed that most of studied rocks are mid-ocean ridge basalt (MORB). The studied amphibolites have been subjected to amphibolite facies metamorphism.
