Empirical Distance Metrics Relationships and Uncertainties in Seismic Hazard Assessment
Authors: Kayastha Melish , Pezeshk Shahram , Tavakoli Behrooz 
Published: March 2023

ABSTRACTThe seismic hazard of an area is determined based on the ground motion observed at that site. The intensity of the ground motion can be predicted using ground -motion models (GMMs). GMMs typically use distance metrics such as the Joyner–Boore distance (RJB) and the rupture distance (RRUP). However, apart from RJB and RRUP, probabilistic seismic hazard analysis (PSHA) also utilizes point-source-based distances like the epicentral distance (REPI) and the hypocentral distance (RHYP). These distance metrics are used for point sources when the fault geometry is unknown or is ignored. To obtain an accurate seismic hazard of an area, we need to determine the relationship between the distance metrics. In this study, we develop empirical relationships between RJB and various other distance metrics. This method avoids conducting computationally intensive tasks such as computing finite-fault-based distances for different fault geometry of a virtual rupture plane for each point source. The empirical equations provide the relation between RJB and target distance metric (Rtarget) based on the magnitude of the earthquake and the dip angle of the fault. In addition, we also require the depth to the top of the rupture to calculate RHYP. We discuss the steps to include the variability due to the conversion of the distance metrics in the PSHA. We have compared the results of this study with other published studies for distance conversion. A simple PSHA study of a circular area of 100 km using Pezeshk et al. (2011) as the GMM determined an increase in hazard using the proposed empirical equations and their uncertainties. The equations developed in this study can be directly applied in PSHA and are independent of the GMMs used for seismic hazard calculations. The equations can also be used for different fault geometries with a range of dip angles varying from 10° to 90°, for magnitudes 5.0–8.0, and distances up to 200 km. We have focused on the central and eastern United States.
Emprendimiento juvenil
Authors: Meneses Perez Carlos Alveiro 
Published: March 2023

El emprendimiento juvenil en Colombia, se ha visto permeado por la crisis socioeconómica por la que atraviesa el país. Esto, teniendo en cuenta que la precariedad laboral va en aumento y las garantías en el trabajo que actualmente tienen los jóvenes se ven reducidas en los diferentes ámbitos, lo que lleva al interés por realizar un balance en materia de emprendimiento y reconocer las tendencias de producción académica y los desafíos que enfrentan los jóvenes al querer emprender bajo el complejo contexto social, político y económico del país. Para ello, se realizó un estudio documental de carácter descriptivo, a fin de identificar los aspectos que han sido abordados en las diferentes publicaciones frente al emprendimiento juvenil de cara a la realidad social del tema en Colombia, lo que llevó a concluir que existen diferentes factores que posibilitan el emprendimiento en el país, cuyas tendencias se orientan en el desarrollo del perfil del emprendedor que principalmente se orienta a la creatividad, la innovación, la autonomía, el aprovechamiento de las oportunidades y el asumir riesgos, las motivaciones encaminadas en muchos casos a tener su propio negocio, satisfacer sus necesidades, contrarrestar la falta de oportunidades, adquirir habilidades, capacidades y destrezas, entre otras como el desarrollar iniciativas innovadoras. Sin embargo, se presentan obstáculos que impiden en muchos casos que los emprendimientos permanezcan en el mercado, determinando entonces, que los principales desafíos a considerar se enmarcan en la capacitación, formación y desarrollo de elementos claves en el proceso y que deben ser propiciados principalmente por el Estado y las instituciones educativas.

O presente artigo tem como objetivo analisar a estética das “cenas” contemporâneas
de música eletrônica soturna com base em usos e estratégias
comunicacionais de seus participantes na rede social MySpace(http://www.myspace.com). Partimos da influência do romantismo gótico no imaginário da cibercultura (Amaral 2006), propondo um neologismo provocador: o cibergoticismo, aqui compreendido como um
elemento herdeiro da discursividade do romantismo gótico, mas transmutado na sociabilidade e nas trocas informacionais no âmbito das cibersubculturas (Bell 2000; Caspary & Manzenreiter 2003) e suas cenas musicais correspondentes (rivetheads, cibergóticos, neovitorianos).

ABSTRACT
This paper has the aim to analyse the aesthetics of contemporary darkelectronic music scene, departing from the uses and communicational strategies of their participants inside the social network MySpace (http://www.myspace.com). Our starting point is the influence of gothic romanticism inside the cyberculture imaginary (Amaral 2006), proposing a teas-ing neologism: cybergothicism. We understand this concept as an heir of
gothic romanticism discursivity, but it has turned into the sociability and informational exchanges inside cybersubcultures (Bell 2000; Caspary &
Manzenreiter 2003) as well as its derivative musical scenes (rivetheads, cybergothics and neovictorians).

Sarcopenia: prevalence and its main risk factors in older women
Authors: Bogucka Aleksandra , Kopiczko Anna , Charzewska Jadwiga 
Published: March 2023

Introduction: Sarcopenia is a major public health concern. It is defined as a progressive and gen­eralized skeletal muscle disorder that is associated with an increased likelihood of falls, fractures, physical disability, and ultimately, premature death.
Objective: The aim of the study was to assess the prevalence and determine the role of physical activity, nutrient intake, and selected risk factors for the development of sarcopenia in older women.
Methods: The study involved 302 women aged ≥65 years (mean age: 72.1± 5.9 years). Bioelectrical impedance analysis of body composition, static muscle strength measurements, Timed Up and Go test, and the assessment of current physical activity using accelerometers were performed. Diets were assessed using the 24-h recall method from two non-consecutive days. The energy and nutrient content of diets was calculated using the computer program DIETA 6.
Results: Sarcopenia was present in 28.8% of the women studied. The most important factor in the decrease in the risk of sarcopenia was protein intake ≥ 0.9 g/kg b.m. (OR=0.08;p<0.001), and physical activity ≥ 4000 steps/day. However, these results were not statistically significant (OR=0.58; p=0.08). Furthermore, the risk of developing sarcopenia increased as BMI (OR=1.36; p<0.001) or percent of body fat (OR=1.29; p<0.001) increased.

Abstract. The paper investigates some characteristic features of the electromagnetic field of a relativistic charged particle that uniformly rotates about a conductive ball in its equatorial plane. It is assumed that the braking of the particle due to radiation is compensated by an external influence (e.g. the electric force) that compels the particle to turn uniformly in a circle. The magnetic permittivity of the ball is assumed to be one. The work is based on the corresponding exact analytic solutions of Maxwell’s equations. The generalized Drude-Lorentz-Sommerfeld formula for the dielectric function of the conductive ball is used in numerical calculations. It is shown that localized oscillations of a high-amplitude electromagnetic field can be generated at a given harmonic inside the ball at a certain (resonant) particle rotation frequency at a small distance from the surface of the ball. Herewith, at large distances from the trajectory of the particle, these localized oscillations are accompanied by intense radiation at the same harmonic, which is many times more intense than the analogous radiation in the case when the ball is absent. The possibilities of using this phenomenon to develop sources of quasi-monochromatic electromagnetic radiation in the range from giga- to terra hertz frequencies are discussed.

Published: March 2023

Aim: To evaluate the impact of xerostomia, edentulism, use of dental prosthesis, and presence of chronic diseases on quality of life in relation to oral health in institutionalized elderly individuals. Methods: This is a cross-sectional study. A questionnaire was administered containing the following instruments: Oral Health Impact Profile (OHIP-14), which measures the quality of life related to oral health; the Summated Xerostomia Inventory questionnaire (SXI-PL) for evaluation of xerostomia, sociodemographic data, clinical description, and patient-reported factors was assessed (edentulism, use of dental prostheses, and chronic diseases). Results: Most elderly individuals did not have any teeth in their mouths and used dental prosthesis. The impact on quality of life, considering the mean of the OHIP-14 scores, was positive in 58.3% of the elderly. Those who used a dental prosthesis were three times more likely to have their oral health negatively impacted (OR=3.09; 95%CI =1.17 8.11), compared to those who did not use, and individuals with xerostomia were more likely to have their oral health negatively impacted (OR=1.57; 95%CI=1.25-1.98) compared to those without xerostomia. There was no difference in the quality of life of individuals with and without chronic diseases. Conclusions: The feeling of dry mouth and use of dental prostheses negatively impacted the quality of life in relation to oral health of the elderly.
Possible Fault Communication between the Memphis Sand Aquifer and the Mississippi River
Authors: Martin Richard V. , Van Arsdale Roy B. , Harrison Valarie J. 
Published: March 2023

ABSTRACT
The Eocene Memphis Sand aquifer is the major source of drinking water for municipalities in the upper Mississippi Embayment, with the city of Memphis, TN, being the largest consumer. Concerns about contamination of the Memphis aquifer from surface waters have primarily focused on local groundwater transmission through the Upper Claiborne aquitard and erosional windows through the aquitard. This study used recent fault mapping to show that faults extend upward from the Memphis aquifer to very near the surface in and adjacent to Memphis. The Meeman-Shelby and Cuba faults extend under the Mississippi River and upward to the base of the Mississippi River alluvium. Groundwater levels (potentiometric surface) in Memphis aquifer monitor wells H002 and LdF 004 and the Mississippi River water levels during the years of 2007 through 2011 show strong correlation (0.744829 and 0.779691, respectively). We believe this correlation may be due to direct connection through fault zones.
Impact of cognitive reserve on bipolar disorder: A systematic review
Authors: Matsumoto Kazuki , Hamatani Sayo 
Published: March 2023

Abstract
Background: Cognitive reserve (CR) is a complex concept that includes premorbid IQ, years of education, and exposure to neuropsychological stimuli through work and leisure. Previous studies have suggested that CR has a positive impact on several aspects of bipolar disorder. Synthesizing the evidence to date is an important work in providing directions for future studies. The objectives of this systematic review to summary impact of CR on onsetting, relapsing bipolar episodes, buffering cognitive dysfunctions, and maintaining quality of life (QOL) in bipolar disorder.
Methods: Two researchers independently reviewed selected paper from three database as PubMed, PsychINFO, and Web of Science. The search keywords were "bipolar disorder" and "cognitive reserve." The selected studies were classified as the levels of evidence according to the criteria of the Oxford Center for Evidence- Based Medicine. The results of the selected studies were summarized according to the objectives.
Results: Twenty-four studies were included in this review. People with high CR may have fewer bipolar episodes and alleviate cognitive impairments and dysfunction. CR may keep the functional level in patients with bipolar disorder.
Conclusions: The results of this systematic review suggest that CR may be involved in preventing relapse of bipolar episodes and may alleviate cognitive dysfunction. However, effect on prevention of onset-risk and relapse of bipolar episodes need further investigation in prospective studies.

Published: March 2023

Abstract

Lead is a very toxic metal which affects human health. An alternative to remove it from contaminated water is the use of macrophytes, as Scirpus americanus. This species is tolerant to salt and metals, and has high biomass. The present research analyzed the capacity of hydroponic cultures of normal and transgenic plants (line T12) from S. americanus to remove high concentrations of lead (100, 250 and 400 mg kg-1 Pb). The MINTEQ3.1 program was used to define the media composition in order to have the metal available to the plants. The presence of metal did not affect the growth of roots and stems at all concentration tested. The normal and T12 plants accumulated 69389 and 45297 mg lead kg-1, respectively, and could be considered as hyperaccumulators. The bioconcentration factor indicated that plant bioconcentrated between 192-300 times the metal. The activation of the antioxidant mechanisms seems to participate in lead tolerance. Then, S. americanus could be used for phytoremediation of water contaminated with high concentration of lead.

Authors: Atim Martha , Mwebesa Ivan , Ssebowa Andrew , Etoko Christine Atala , Kirabira Joseph 
Published: March 2023

Abstract
Background: Depression is a mental disorder characterized by depressed mood and affects more than 300 million people globally. Caregivers of children with Sickle cell disease (SCD) experience psychosocial distress which predisposes them to depression. This study aimed to determine the prevalence of and factors associated with severe depression among caregivers of children with SCD attending a large hospital in post conflict northern Uganda.
Methods: A cross sectional study was conducted at the SCD clinic of St. Mary’s Hospital Lacor. Caregivers of children aged between 0 to 17 years with SCD were interviewed using Patient Health Questionnaire-9 and socio-demographics questionnaire developed by the researchers.Bivariable analysis using chi square test and multivariable logistic regression were conducted to assess associated factors.
Results: 310 participants were recruited consecutively of whom 90% were female and 10% male with mean age of 32.7 years. The prevalence of severe depression among caregivers of children with SCD at SMHL was 18.4% and was associated increasing age of caregiver (adjusted odds ratio (aO.R) =1.06, C.I = 1.02-1.10). Having more than one child (aO.R= 0.321, C.I = 0.107-0.967), and extended family type (aOR= 0.284, CI= 0.114-0.537) were protective against depression.
Conclusion: The study findings indicate that a substantial proportion of caregivers of children with SCD suffer from severe depression which is mostly undiagnosed and hence untreated. Therefore, policymakers need to focus on designing strategies aimed at controlling and managing depression among caregivers of children with SCD such as routine screening.

Abstract

Genetic variation at the 19q13.3 KLK locus is linked with prostate cancer susceptibility. The non-synonymous KLK3 SNP, rs17632542 (c.536T>C; Ile163Thr-substitution in PSA) is associated with reduced prostate cancer risk, however, the functional relevance is unknown. Here, we identify that the SNP variant-induced change in PSA biochemical activity as a previously undescribed function mediating prostate cancer pathogenesis. The ‘Thr’ PSA variant led to small subcutaneous tumours, supporting reduced prostate cancer risk. However, ‘Thr’ PSA also displayed higher metastatic potential with pronounced osteolytic activity in an experimental metastasis in-vivo model. Biochemical characterization of this PSA variant demonstrated markedly reduced proteolytic activity that correlated with differences in in-vivo tumour burden. The SNP is associated with increased risk for aggressive disease and prostate cancer-specific mortality in three independent cohorts, highlighting its critical function in mediating metastasis. Carriers of this SNP allele had reduced serum total PSA and a higher free/total PSA ratio that could contribute to late biopsy decisions and delay in diagnosis. Our results provide a molecular explanation for the prominent 19q13.3 KLK locus, rs17632542 SNP, association with a spectrum of prostate cancer clinical outcomes.
