Environmental Justice and Nuclear Accidents: The Case of Chernobyl Disaster
Authors: Akyüz Emrah
Published: April 2021

Nuclear energy is one of the most important components of the world electricity supply in today's world. It provides approximately 21% of electricity in OECD countries. However, there has been a growing social and academic debate over the use of nuclear energy because the fact that there have been serious incidents and accidents at nuclear power stations indicates that the security risk associated with NPPs is not low. Particularly major nuclear accidents, Fukushima and Chernobyl, can cause the release of radiation into the environment. However, environmental contamination is not shared equally among people which triggers environmental injustice issues. There has been no comprehensive research that investigates nuclear accidents from the perspective of environmental justice theory so far. The main purpose of this study is to argue whether or not nuclear accidents cause environmental injustice. The results show that the major nuclear accident, the Chernobyl, has caused distributive and intergenerational environmental injustice.
Tsunami Hazard Assessment and Potential Risk Mitigation Requirement for Sea of Marmara Coastline
Authors: Salar Ayhan , Gazioğlu Cem
Published: April 2021

The westward movement of the seismic energy along the North Anatolian Fault (NAF) during the 20th century has increased the probability that the next activity will be offshore in the Sea of Marmara. According to historical records 35 tsunami events have impacted the Sea of Marmara coasts (Altınok, et al., 2011). Offshore seismic sources may trigger these tsunamis directly or through coseismic underwater failure. The 1999 İzmit Bay tsunami led to more comprehensive analyses of these events which are generally caused by underwater failures close to the target coastline. Waves so generated can arrive at nearby coastlines in minutes, causing extensive damage and loss of life. Here this paper proposes, on the basis of tsunami models in the Sea of Marmara and methodology used internationally, tsunami inundation maps for the areas along the Sea of Marmara coasts in the light of both remote sensing and DTMs data. This investigation highlights the information regarding the most vulnerable tsunamigenic areas. Such maps for selected areas help to understand the possible effects on those regions and should only be used for evacuation planning and reducing possible hazard

Published: May 2021

There are problems unsettled by manufacturers and installers of ventilation equipment during the design and definition of economy of its use connected with the absence of taking into account specific peculiarities of conditions for its operation and definition of reliable initial data for designing that causes errors during designing and unjustified expectations of a customer. There are obtained analytical dependences allowing the definition of reliable initial data for designing ventilation equipment with the recuperator of the heat of air removed for the specific conditions of operation in an engineering workshop. On their basis there is developed an algorithm for the computation of money savings taking into account actual energy consumption in value terms while overcoming aerodynamic resistances, a technique for the automated choice of essential equipment is also shown. The problem of the theoretical definition of incoming air temperature at the output of the recuperator Tin. air re. is solved. For computation automation there is carried out an approximation of data by mean temperature Tatm during diurnal hours Tatm day and nocturnal ones Tnoct. of the day for the last ten years for the eastern areas of Belarus and regression equations are obtained. The algorithm obtained in combination with analytical dependences for the definition of the condensate volume formed in the recuperator at the efficient arrangement of the ventilation equipment make a methodology for the complex approach at designing ventilation equipment with the heat recuperator for enterprises of engineering industry. The methodology mentioned allows designing a ventilation system for the workshop of an engineering enterprise in accordance with specific conditions of its operation it also allows defining a reliable value of economy of funds taking into account actual loss.
Propitious time in Entrepreneurship
Authors: Leong David
Published: April 2021

Time is not invariant in the entrepreneurial journey. Timing is everything in entrepreneurial venturing. This
paper shifts the inquiry of entrepreneurship from micro (traits, characteristics and behaviour) and macro
(environmental context) perspective and the multi-level approaches from discovery, creation to co-creation
(Garud et al., 2014) to a study of the relevance of time in the entrepreneurial pathway development. The context
of luck or exogenous change or external or internal perturbation that may lead to the propitious time to act will
be examined with reference to research conducted by Peter R. Darke (Darke & Freedman, 1997). It needs
contextualization to fit the entrepreneurial paradigm on the propitious time to enact (Weick & Karl E, 1995)
which is the main conceptualization in this paper. The concept of convergence, in a particular spatial-temporal
(space-time), between the opportunity and the entrepreneur, is the core of this study and this paper will focus
specifically on the extent and nature of this convergence in relation to time. Propitious time to trigger actions
when opportunities surface or avoidance when the scale of risks are too large to bear- this study of when to act
is therefore central to the theory of entrepreneurship.
Unified Theory Of Gravity and Electromagnetism : Classical and Quantum Aspects
Authors: Avik@
Published: April 2021

A unified classical theory of gravity and electromagnetism with a torsion vector Г_i≠ 0, proposed by S N Bose in 1952, is introduced. In this theory, the torsion vector acts as a magnetic current and it is shown that (i) the electromagnetism is invariant under continuous Heaviside–Larmor transformations and (ii) the electric and magnetic charges are topologically quantised, satisfying the Dirac quantisation condition, without implying any Dirac string provided Г_iis curl-less.

Published: May 2021

Ivermectin is an anti-helminthic drug that works on humans but not on penguins. This short perspective seeks to understand and offers an explanation to why Ivermectin is unsuccessful on penguins (other avian animals, such as eagles, and more), but has succeeded in the human population. The bioinformatics approach can lead to the potential design of novel derivatives that would be exclusively for veterinary use.
Copulatory Urgency: An Evolutionary Perspective of Women’s Sexual Desire
Authors: Crosby Courtney L.
Published: May 2021

Despite the extensive empirical exploration of sexual desire, only one field explains the proper biological function of this phenomenon—evolutionary psychology. This chapter reviews women’s copulatory urgency—individual differences in the experience or intensity of sexual desire—from an evolutionary psychological perspective. An evolutionary psychological perspective of the function of sexual desire can shed light on how deficits in this motivational force may emerge, which may be useful for clinicians when helping patients understand the etiology of sexual desire concerns. An evolutionary psychological perspective of sexual desire further reveals: (1) why men and women differ in their experiences of sexual desire, (2) how natural selection produces individual differences in sexual desire, and (3) how extremes in sexual desire may be associated with hypersexuality, paraphilias, or an evolutionary mismatch between the adaptive problems faced during our species’ past and the challenges we face today. I begin the chapter by presenting a brief history of research on sexual desire and highlighting the limitations of early models of sexual responding. Next, I discuss the difficulties of measuring sexual desire, and explain how evolutionary meta-theory can be fruitful when examining context-dependent individual differences in sexual desire. I then describe the impact of several important contextual factors (e.g., age, relationship length, parental effort, partner habituation) on variation in women’s sexual desire responses and highlight avenues for future research. The chapter ends by discussing the qualities of compulsive sexual behavior and proposing that extreme variations in sexual desire as we currently understand them may be the result of an evolutionary mismatch. In sum, I suggest that scientists distinguish between sexual desire and sexual arousal, consider evolutionary meta-theory when thinking about context-dependent variation in sexual desire, and be cognizant of potential confounds when examining women’s sexual desire responses.

Published: May 2021

This study investigated the content of parenting information shared on social media by identifying the range and frequency of topics shared by parenting-focused accounts on Twitter. Using the Twitter API, a universe of 675,069 tweets were gathered from 74 of the most-followed parenting-focused accounts, or ‘hubs’, from January 2016 to June 2018. Using a custom, semi-automated topic modeling approach, we identified the topics – and subtopics within topics – parenting hubs shared with their followers and investigated whether any meaningful differences in topical focus existed between accounts targeting mothers versus fathers. Results indicate that over one third of tweets were about Parenting Behavior and nearly one quarter about Health, with Entertainment, School and Motherhood and Fatherhood generally as less tweeted topics. Mother-focused accounts tweeted more about Health than father-focused accounts, which tweeted more than others about Entertainment. Implications for future parenting and social media research are discussed.

Published: April 2021

The major aim of this paper is to report the finding of a study that aims at analyzing different factors influencing teacher motivation towards the teaching profession. To this goal, a mixed method approach was used and quantitative data were collected from 430 teachers, teaching at the Basic Level, from six districts using a set of questionnaires. Qualitative data were gathered from 48 teachers, six resources persons, six teacher trainers and three policy-makers. The major findings of the study show that multiple factors influence teacher motivation towards teaching profession, which are broadly categorized under four areas: individual, school related, socio cultural and political. Policy-related factors include salary and benefits, leave facility, promotion, training, pensions and freedom to trade union. Similarly, school-related factors for teacher motivation include school management, leadership, teaching load, professional development opportunities and feedback and reinforcement mechanism. Student-related factors contain class size, student composition, regularity, and discipline. Socio-cultural factors for teacher motivation include social recognition of teachers, political interference and teacher-parent cooperation. Finally, the issue of teacher performance and motivation should be tied up with the policies of teacher professional development.

A wide variety of anomalies may occur as a result of the vitello- intestinal duct (VID) failing to obliterate completely. These anomalies occur in approximately 2% of the population and may remain silent throughout life or may present incidentally with an intra-abdominal complication. Complete patency of vitello-intestinal duct is the rarest of all the anomalies of VID. We report a case of 27 day old female presenting with pinkish umbilical mass since birth referred to us by a paediatrician as umbilical granuloma, which turned out to be patent vitello- intestinal duct.
Interwar India through Bhimrao Ambedkar’s Eyes
Authors: Sandhu Tanroop
Published: April 2021

This article is an analysis of the political thought of Bhimrao Ambedkar, anti-caste activist, author of the Indian constitution and first law minister of independent India. His personal writings are analyzed, and the origins of his ideas are situated within larger contexts- both national and international. He was representative of the increased radicalism of the Indian nationalist movement in the 1920s and 30s, but he stood apart from the mainstream of the movement on key issues. Above all, the most formative influence on his political philosophy was the fact that his experience of interwar India was mediated through his position at the lower rungs of the caste hierarchy. He brought his unique perspective to bear on some of the most pressing topics that radical nationalists were debating in the interwar period: communism and political economy, defining nationhood, and the caste system. A discussion of Ambedkar’s views on these three key subjects forms the analytical basis of this article, with an eye towards the continued relevance of his thought.
What Reading Austin Clarke Can Teach Us about Black Lives Matter
Authors: Medovarski Andrea
Published: May 2021

This article considers the ways in which some of Austin Clarke’s writings might be understood as an expressive and intellectual blueprint for the activism of Black Lives Matter (BLM). Clarke’s radical politics can be seen in the ways he reconceptualizes Canadian citizenship and Black activism, and in the ways his fiction and nonfiction writing interrogates respectability politics in order to take seriously the full range of emotions – including rage – experienced by Black people and Black communities in the face of ongoing state violence and police brutality. Clarke’s refusal of respectability politics in particular anticipates some of the concerns of BLM, such as its reinvigoration of grassroots resistance, direct action, and confrontation politics, and the ways the movement writes alternate narratives through which to read dominant representations of the victims of state-sanctioned violence. Clarke’s writing also suggests that these reimaginings are particularly urgent in a Canadian context shaped by settler-colonial discourses of so-called “politeness” and “civility.” His work, instead, lays bare the long history and everyday pervasiveness of anti-Black racism, “anti-Black sanism” (Meerai, Abdillahi and Poole 2016), and police brutality in Canada, in ways few other writers have.

Published: April 2021

A recente pandemia causada pelo novo coronavírus desencadeou um cenário de elevada incerteza e seus impactos certamente tendem a ser sentidos no mercado de trabalho. A partir de uma pesquisa de natureza exploratória, conjugada com revisão bibliográfica, buscou-se realizar uma discussão e reflexão sobre como as desigualdades de inserção laboral juvenil, bem como as desigualdades sociais, já existentes na sociedade brasileira, foram significativamente ampliadas em decorrência das medidas de contenção e transmissibilidade da propagação do vírus. Os resultados sugerem que as ações de combate e retardamento da COVID-19, aliadas ao cenário político e econômico nacional, considerado ainda mais incerto nesse momento atual, contribuíram para o aprofundamento da crise econômica e social, tornando determinados grupos sociais ainda mais vulneráveis, como é o caso dos jovens, em termos de precarização ou perda do trabalho, redução dos rendimentos, problemas relacionais e psicológicos.

Published: May 2021

Some distribution transformers in densely populated areas have a loading percentage of more than 100% and also less than 10%. This problem shows that the use of a distribution transformer is inappropriate. With descriptive, correlational and comparative research methods, it is hoped that it can optimize the placement and capacity selection of distribution transformers. Data were taken from 25 people living in the Pemecutan Kelod and Tegal Harum areas using questionnaires and interviews. The data were tested using the T and Pearson tests to determine the effect of placing the distribution transformer. The results of equalization of the load with the addition of a new distribution transformer and relocation of the distribution transformer capacity to the feeder are expected to get optimal results. The technical solution is obtained with a voltage of less than 10% and a distribution transformer capacity that is in accordance with the growth of the population electrical load. Socially and culturally, for the level of conformity there is an increase in the harmony of the population after the placement of a new distribution substation (t = -7.71 and p <0.05), for the comfort level there is an increase in the comfort of the population after the placement of a new distribution substation (t = -9.57 and p <0.05), and for the level of security there was an increase in the tranquility of the population after the placement of a new distribution substation (t = -8.42 and p <0.05). The relationship between suitability and comfort obtained a very strong relationship (r = 0.90), the relationship between suitability and safety obtained a very strong relationship (r = 0.85), and the relationship between comfort and safety obtained a very strong relationship (r = 0.86).
Association of Continuous Vertebral Bone Bridges and Bone Mineral Density with the Fracture Risk in Patients with Diffuse Idiopathic Skeletal Hyperostosis
Authors: Furukawa Mitsuru , Okuyama Kunimasa , Ninomiya Ken , Yato Yoshiyuki , Miyamoto Takeshi , Nakamura Masaya , Matsumoto Morio
Published: April 2021

Study Design: Cross-sectional study.Purpose: To examine whether the number of continuous vertebral bone bridges and bone mineral density (BMD) influence the fracture risk in diffuse idiopathic skeletal hyperostosis (DISH) patients.Overview of Literature: Bone bridges connecting through the intervertebral body in DISH create long lever arms that can increase the risk of fractures from minor trauma. DISH patients have a BMD that is higher than or comparable to those of age-matched healthy subjects.Methods: We examined the computed tomography scans from the thoracic vertebra to the sacrum used to diagnose DISH in 140 patients (98 men and 42 women; average age, 78.6 years). We compared patients who did (n=52) and did not have (n=88) fractures at the continuous vertebral bodies fused by bone bridges. The relationship between the vertebral fractures and the maximum number of vertebrae that are bony cross-linked with contiguous adjacent vertebrae (max VB) from the thoracic vertebra to the sacrum or from the lumbar vertebra to the sacrum and proximal femur BMD were analyzed using a logistic regression model.Results: We found that after adjusting for the confounding factors, higher max VB, both from the thoracic vertebrae to the sacrum and the lumbar vertebrae to the sacrum, was associated with a higher risk of vertebral fractures. This difference was statistically significant. The risk was higher when only the lumbar vertebrae to the sacrum was considered (thoracic vertebrae to the sacrum: odds ratio, 1.21; p<0.05; lumbar vertebrae to the sacrum: odds ratio, 2.78; p<0.01). Moreover, low proximal femur BMD in DISH patients raises the fracture risk (odds ratio, 0.47; p<0.01).Conclusions: Many continuous vertebral bone bridges, especially those that extend to the lumbar spine and low proximal femur BMD, are risk factors for fracture in DISH patients.
Preventive and Restorative Responses of Broccoli Sprouts on Biomechanical Structures, Histomorphometric, and Gene Expression Levels of Degenerated Intervertebral Disc in Rabbit Model
Authors: Ogunlade Babatunde , Fidelis Obinna P. , Adelakun Sunday Aderemi
Published: May 2021

Study Design: Symptomatic disk degeneration is characterized by early pathological changes in the morphological, biochemical, and biomechanical properties of the intervertebral disc (IVD). Several methods that can be used to resolve this condition are being researched.Purpose: The present study was designed to examine the preventive and restorative properties of broccoli sprouts extracts in an annular puncture rabbit model of IVD degeneration.Overview of Literature: IVD degeneration is closely associated with low back pain. A degenerated IVD is cytoarchitecturally characterized by a reduction in cell number, morphological changes in the disk tissue, and changes in the extracellular matrix contents. Methods, such as imaging and biochemical characterization, have been used for distinguishing between degenerated disk and non-degenerated disk.Methods: Twenty New Zealand white rabbits (weighing approximately 2.0–3.5 kg) were divided into four groups (n=5). Group 1 received 50 mg/kg of normal saline solution orally for 4 weeks; group 2 received 50 mg/kg of normal saline solution immediately after puncture for 4 weeks; group 3 received 300 mg/kg of aqueous extract of broccoli sprouts orally immediately after puncture for 4 weeks; and group 4 received 300 mg/kg of aqueous extract of broccoli sprouts after 4 weeks of puncture for another 4 weeks. After the experiment, the disk height index (DHI), histomorphometry, and gene expression level were measured and analyzed.Results: The photomicrograph showed that the histological features of the punctured-treated groups (groups 3 and 4) were more similar to those of the non-punctured group than those of the punctured non-treated group. There was a significant difference in the DHI and relative gene expression levels among the non-treated punctured groups compared with those of the non-punctured and punctured-treated groups, respectively.Conclusions: This study shows that the aqueous extract of broccoli sprouts exerts preventive and restorative effects in a rabbit model with disk degeneration.
Accuracy of Percutaneous Pedicle Screw Placement after Single-Position versus Dual-Position Insertion for Lateral Interbody Fusion and Pedicle Screw Fixation Using Fluoroscopy
Authors: Hiyama Akihiko , Katoh Hiroyuki , Sakai Daisuke , Sato Masato , Tanaka Masahiro , Watanabe Masahiko
Published: May 2021

Study Design: Retrospective study.Purpose: The purpose of this study was to compare the accuracy of percutaneous pedicle screw (PPS) placement between prone and lateral decubitus positions during lateral lumbar interbody fusion (LLIF) and to evaluate the tendency of PPS positioning based on simple computed tomography measurements with patients in the lateral decubitus position.Overview of Literature: There is insufficient information in the literature regarding the accuracy of inserting a PPS using fluoroscopy in patients in the lateral decubitus position.Methods: We included 62 patients who underwent combined LLIF surgery and PPS fixation for degenerative lumbar spondylolisthesis with spinal canal stenosis. We compared the patient demographics and the accuracy of fluoroscopy-guided PPS placement between two groups: patients who remained in the lateral decubitus position for the pedicle screw fixation (single-position surgery [SPS] group) and those who were turned to the prone position (dual-position surgery [DPS] group).Results: There were 40 patients in the DPS group and 22 in the SPS group. Of the 292 PPSs, only 12 were misplaced. In other words, 280/292 screws (95.9%) were placed correctly in the pedicle’s cortical shell (grade 0). PPS insertion did not cause neurological, vascular, or visceral injuries in either group. The breach rates for the DPS and SPS groups were 4.1% (grade 1, 5 screws; grade 2, 3 screws; grade 3, 0 screw) and 4.1% (grade 1, 2 screws; grade 2, 2 screws; grade 3, 0 screw), respectively. Although there were no statistically significant differences, the downside PPS had more screw malpositioning than the upside PPS.Conclusions: We found that PPS insertion with the patient in the decubitus position under fluoroscopic guidance might be as safe and reliable a technique as PPS insertion in the prone position, with a misplacement rate similar to that previously published.

Riedel's lobe (ectopic lobe), also known as the accessory hepatic lobe, consists of an anatomical variation characterized by a tongue-shaped protrusion on the visceral surface of the liver right lobe, fixed by a pedicle. This variant draws attention in the clinical practice, as it can be mistaken for a tumor due to its elongated aspect. The aim of this research was to conduct a study on the anatomical characteristics and clinical and functional peculiarities of the accessory hepatic lobe. The paper is based on a integrative review and observational study on a cadaveric specimen. A cadaver with anatomical variation was used. Data were collected in PubMed, Scielo, and VHL. 257 articles were found in the databases, but only 13 were used for research. In careful review, two rare cases of the accessory lobe in the left lobe of the liver, hypoplastic left lobes, and agenesis of the right hepatic lobe, and often the clinical picture without changes in signs and symptoms were found. These morphological abnormalities' clinical impact is limited in the absence of underlying liver disease, cirrhosis, or known cancer. In case of complications or after the diagnosis of pedunculated tumors in the liver, laparoscopy is well indicated for removing these lobes or tumors.

Published: May 2021

Investment in unrenewable energy sources has grown at a rapid pace during the beginning of the 21st century, and they may be exhausted by the middle of this century if this rhythm of consumption is maintained. Sustainable solutions have become a priority and the use of Geothermal Energy from Surface Water has attracted interest as a source of clean and renewable energy which can be used to climatize constructed environments. This article analyzes the surface water of a reservoir located in Fátima do Sul, Mato Grosso do Sul determining its temperature at depths of 0.3 to 1.5 meters (1 to 5 feet) using our own method which employs an Arduino Mega 2560 R3, a free electronic hardware prototype with a single board. The results demonstrate an inverse relationship between the variation in the water’s temperature and an increase in depth, or in other words, there are smaller variations in temperature at greater depths. This fact gives these waters the capacity to store heat, and thus it can be employed in heating and cooling constructed environments.
Responsive neurostimulation for the treatment of medically refractory epilepsy in pediatric patients: strategies, outcomes, and technical considerations
Authors: Mortazavi Armin , Elliott Ross-Jordon S. , Phan Tiffany N. , Schreiber John , Gaillard William D. , Oluigbo Chima O.
Published: April 2021

OBJECTIVE

Children with medically refractory partial-onset epilepsy arising from eloquent cortex present a therapeutic challenge, as many are not suitable for resective surgery. For these patients, responsive neurostimulation may prove to be a potential tool. Although responsive neurostimulation has demonstrated utility in adults, little has been discussed regarding its utility in the pediatric population. In this study, the authors present their institution’s experience with responsive neurostimulation via the RNS System through a case series of 5 pediatric patients.

METHODS

A single-center retrospective study of patients who underwent RNS System implantation at Children’s National Hospital was performed.

RESULTS

Five patients underwent RNS System implantation. The mean patient age at treatment was 16.8 years, and the average follow-up was 11.2 months. All patients were considered responders, with a seizure frequency reduction of 64.2% without adverse events.

CONCLUSIONS

All 5 patients experienced medium-term improvements in seizure control after RNS System implantation with decreases in seizure frequency > 50% from baseline preoperative seizure frequency. The authors demonstrated two primary configurations of electrode placement: hippocampal or amygdala placement via an occipitotemporal trajectory, as well as infratemporal surface electrodes and surface electrodes on the primary motor cortex. No adverse events were experienced in this case series.

Published: April 2021

OBJECTIVE

An advantage of lateral lumbar interbody fusion (LLIF) surgery is the indirect decompression of the neural elements that occurs because of the resulting disc height restoration, spinal realignment, and ligamentotaxis. The degree to which indirect decompression occurs varies; no method exists for effectively predicting which patients will respond. In this study, the authors identify preoperative predictive factors of indirect decompression of the central canal.

METHODS

The authors performed a retrospective evaluation of prospectively collected consecutive patients at a single institution who were treated with LLIF without direct decompression. Preoperative and postoperative MRI was used to grade central canal stenosis, and 3D volumetric reconstructions were used to measure changes in the central canal area (CCA). Multivariate regression was used to identify predictive variables correlated with radiographic increases in the CCA and clinically successful improvement in visual analog scale (VAS) leg pain scores.

RESULTS

One hundred seven levels were treated in 73 patients (mean age 68 years). The CCA increased 54% from a mean of 0.96 cm2 to a mean of 1.49 cm2 (p < 0.001). Increases in anterior disc height (74%), posterior disc height (81%), right (25%) and left (22%) foraminal heights, and right (12%) and left (15%) foraminal widths, and reduction of spondylolisthesis (67%) (all p < 0.001) were noted. Multivariate evaluation of predictive variables identified that preoperative spondylolisthesis (p < 0.001), reduced posterior disc height (p = 0.004), and lower body mass index (p = 0.042) were independently associated with radiographic increase in the CCA. Thirty-two patients were treated at a single level and had moderate or severe central stenosis preoperatively. Significant improvements in Oswestry Disability Index and VAS back and leg pain scores were seen in these patients (all p < 0.05). Twenty-five (78%) patients achieved the minimum clinically important difference in VAS leg pain scores, with only 2 (6%) patients requiring direct decompression postoperatively due to persistent symptoms and stenosis. Only increased anterior disc height was predictive of clinical failure to achieve the minimum clinically important difference.

CONCLUSIONS

LLIF successfully achieves indirect decompression of the CCA, even in patients with substantial central stenosis. Low body mass index, preoperative spondylolisthesis, and disc height collapse appear to be most predictive of successful indirect decompression. Patients with preserved disc height but severe preoperative stenosis are at higher risk of failure to improve clinically.

Introduction: Typhoid fever and paratyphoid fever commonly called as enteric fever is a life-threatening illness caused by Salmonella serotype Typhi and Salmonella serotype Paratyphi, respectively. It is a major public health issue in underdeveloped and developing countries. The aim of the study is to find out the prevalence of enteric fever pathogens in blood culture of patients attending a tertiary care centre.

Methods: A descriptive cross-sectional study was conducted in 3483 blood samples of patients attending a tertiary care centre, with the history and symptoms suspicious of enteric fever during one year period from mid-September 2019 to mid-September 2020 after ethical approval from the institutional review committee. Isolates were identified by standard microbiological methods and tested for in vitro antibiotic susceptibility by modified kirby-bauer disc diffusion method. The obtained data was entered and analyzed in WHONET 5.6 program, point estimate at 95% was calculated along with frequency and proportion for binary data.

Results: In our study, enteric fever pathogens were isolated from 18 (0.51%) blood samples. Out of which, Salmonella Paratyphi A was isolated from 10 (8.19%) and Salmonella Typhi was isolated from 8 (6.55%) blood samples. Other serotypes were not isolated. Antimicrobial susceptibility test showed that salmonella species that was isolated were sensitive to most of the drugs.

Conclusions: Prevalence of enteric fever pathogens was lesser compared to other studies. Varying degrees of antibiotic resistance among isolated enteric fever pathogens necessitates continuous surveillance of the susceptibility patterns. Prudent use of antimicrobials, active infection control practices and stringent antibiotic policy should be implemented to prevent emergence of antibiotic resistance and future outbreaks.

Introduction: Varicosity is the common problem of various etiology having simple limb aching to worst complications like oedema, ulcer, and skin changes. Minimal invasive endovenous laser therapy is a noble procedure. The aim of the study is to find out the recurrence of the varicose vein after laser therapy in a tertiary care center.

Methods: This descriptive cross-sectional study was done in 38 patients with varicosity of the lower limb in a tertiary care hospital, from January 2019 to June 2019 after taking ethical clearance from Institutional Review Committee. Convenience sampling was done. Data was collected and entry was done in Statistical Package for the Social Science software version 22, point estimate at 90% Confidence Interval was calculated along with frequency and proportion for binary data.

Results: We recorded 38 patients with ablated limb out of which none of the ablated veins showed recanalization in six months follow up. Twenty two (58%) patients were male and 16 (42%) patients were female with a mean age of 40.26 years. Major bulk, 23 (60.5%) resumed activity in second postoperative day and only 1 (2.6%) patient waited for 5 days for normal activity with mean of 2.58 days postoperatively. Sixteen (42.1%) patients developed erythema or ecchymosis, 12 (31.6%) patients had induration along the long saphenous vein course, 7 (18.4%) patients had paresthesia, 2 (5.3%) patients had limb swelling and 1 (2.6%) patient had skin burn.

Conclusions: Endovenous laser ablation has very low rate of recurrence of varicosity and has minorcomplications.

Introduction: Adolescents comprise individuals in the age group 10 to 19 who are undergoing a period of gradual transition of growth and development. Adolescent girls are at high risk of anemia and malnutrition. This research has been aimed to find the prevalence of anemia in adolescent girls attending specific schools of Panchkhal municipality in Kavrepalanchowk in Nepal.

Methods: A descriptive cross-sectional study was conducted in one government and one private school of Panchkhal Municipality of Kavre district in adolescent girls of age 10 to 19 from December 2017 to April 2018 attending grade five till ten in the field practice area of a medical college. After ethical approval, anthropometric measurements of height, weight, and blood were taken for hemoglobin estimation. Descriptive analysis was done in Microsoft excel 2016.

Results: Out of 95 adolescent girls, fourteen (14.74%) adolescent girls were anemic. The mean age was 13.35Â±1.629 years, mean height and weight were 1.58m and 44.11kg, respectively.

Conclusions: This study shows a lower prevalence of anemia than reported by national data, but it is higher than that reported by developed countries. Anemia and undernutrition have long terms detrimental effects on adolescent girls, so health education and prevention is necessary.
Genetic and environmental contribution to social dominance orientation and its overlap with HEXACO personality traits

Social dominance orientation (SDO), i.e. the preference toward egalitarian or hierarchically arranged relations within a society may be studied from social/contextual, but also dispositional perspective. The aim of the present study was to explore genetic and environmental contribution to the individual differences in SDO, and its overlap with HEXACO personality traits, both at phenotypic and latent genetic and environmental levels. The sample consisted of 830 Croatian twins aged 19 to 28 years who filled-in the self-report measures. Data analyses indicated the heritability of SDO was over 40%, with no evidence for the common environmental influences. SDO phenotypic variance substantially overlapped with Honesty-Humility, Emotionality, and Openness domains. Numerous significant correlations were found at the facet level, with the highest phenotypic overlap for the “interstitial” altruism facet. However, incremental predictive power of personality (over age and sex) was moderate: 13% and 19% of the phenotypic SDO variance was predicted by HEXACO traits at the domains and facet levels, respectively. Multivariate behavioural genetic analysis indicated that 19% and 3% of the genetic and unique environmental variance of SDO overlapped with the genetic and unique environmental variance of personality, respectively. Substantial genetic correlations of SDO with Honesty-Humility and Openness domains were found, while marginal unique environmental correlation was found for Openness domain only. The etiological overlap between SDO and personality represents an argument in favour of taking dispositional along with social/contextual perspective in explaining social behaviour.

Studies investigating the effects of emotion regulation on romantic partners’ relationship satisfaction (RS) found that proneness to use cognitive reappraisal exerts positive, whereas expressive suppression negative effects on both one’s own and partner’s satisfaction. However, no studies explored the effects of partner reported use of the two emotion regulation strategies on RS, which might allow the exclusion of method-related explanations of the previous findings and offer new insights into the mechanisms involved. We tested the hypotheses about the effects of reappraisal and suppression on RS on a sample of 205 romantic couples by using round-robin design and actor-partner interdependence modelling (APIM). Although the effects were relatively small, they were still in line with the assumptions that cognitive reappraisal has positive intra- and interpersonal effects on RS, that they can be generalized across self- and partner reports to a certain extent, and that they are somewhat stronger in women. Considering expressive suppression, only women’s self-reported suppression exerted significant negative intrapersonal effect on RS. Implications of self- and partner reports of emotion regulation for the understanding of the mechanisms mediating its effects on RS are discussed.

The sayur asem is one of the traditional Indonesian dishes, especially the Betawi ethnic group. This study aims to document the local knowledge of vegetable traders in the Kranggan Mas market, the diversity of plants used as an ingredient in sayur asem. The method used in this research was a survey. Data were analyzed qualitatively and descriptively. The sayur asem is a soup-like vegetable that has a sour taste with the main ingredients of melinjo (Gnetum gnemon) leaves and seeds and tamarind fruit (Tamarindus indica). The total of 13 species belonging 12 genera and 10 families used to process of making sayur asem. The part of used to process of making sayur asem is dominated by fruits (8 species), followed leaves and tubers (each 2 species). The melinjo (G. gnemon) is the main ingredient in the making of sayur asem, while Alphinia galanga, Syzygium polianthum and Tamarindus indica are the main spices with a larger volume. The main ingredients and seasonings used mostly have antioxidant and antimicrobial activity and are therefore very good at supporting digestive tract health and providing healthful effects.Keywords: Antioxidant, antimicrobial, gnetum gnemom, tamarindus indica
