Who Is Responsible for the Interpretation of the Endower’s Conditions: An Islamic Perspective
Authors: Al-ashqar Osama
Published: February 2023

The endowment contract involves the donation of profit from assets to charitable causes. It is a contract that may need close interpretation, as conditions included by the endower may be worded ambiguously. This can lead to disputes that disrupt the use of or even freeze endowment assets. Hence, this research aims to determine who is responsible for interpreting an endower's conditions, and who is accountable in the event of an interpreter’s mistake. This study used inductive reasoning to reach several conclusions: the judiciary should be the official body to interpret the conditions of an endower, judicial rulings on the interpretations should be subject to the scrutiny of higher courts, and only judges with the highest levels of competence should be chosen to adjudicate on endowment disputes. The study recommends that endowment contract laws should be periodically updated to ensure their ongoing validity and general applicability and that a system of circuit courts be used to hear and rule on endowment disputes.

Published: February 2023

La Anorexia Nerviosa cuyas siglas son A.N. corresponde a los llamados Trastornos de la Conducta Alimentaria. Esta se caracteriza por una restricción en la ingesta de alimentos, por consecuencia de un peso corporal bajo, además de un miedo intenso a ganar peso y a una alteración en la autopercepción del sujeto. Actualmente, su prevalencia es cada vez mayor y desde edades más tempranas, siendo un factor de riesgo persistente el hecho de ser mujer y adolescente. Es así, como indagar acerca de los rasgos de personalidad que subyacen a dicha patología resulta de gran importancia para la Psicología Clínica, debido a que la información recopilada puede resultar de utilidad para su prevención, tratamiento, recuperación y pronóstico. El presente estudio consiste en una revisión bibliográfica de fuentes con la finalidad de contrastar datos acerca de la presencia de ciertos rasgos en común en pacientes con AN. Se encontró una prevalencia de rasgos de tipo obsesivo, además de alteraciones en la socialización y expresión emocional. De igual forma, se buscó realizar una breve asociación de los trastornos de personalidad mencionados en el manual DSM-V con la AN.

Published: February 2023

El presente trabajo de titulación se realizó con el propósito de determinar la influencia del contexto familiar dentro de la problemática de abuso sexual en niños y niñas, ya sea como culpables o alivio terapéutico. Según la OMS (2003) en la actualidad el abuso sexual es definido como conductas sexuales mantenidas entre dos o más personas, en las que existe un contexto de desigualdad y en la que la víctima es utilizada como medio de estimulación sexual del agresor, se debe tomar en cuenta que la violación es meramente la forma más violenta de abuso sexual conocida. Dentro de las conductas que forman parte del contexto de abuso sexual podemos identificar las siguientes: 1. Contacto físico: genital, bucal o anal. 2. Uso de la víctima como objeto de relajación sexual. 3. Uso de la víctima como objeto de estimulación de terceros: producción de pornografía o manteniendo relaciones sexuales. Durante esta época de modernidad se ha podido comprobar que el abuso sexual infantil y adolescente no solo es el más común, sino que también es el crimen más grave contra los niños en todo el mundo. Según la OMS (2003) el abuso sexual contra menores de edad también incluiría maltrato y vejaciones, tanto físicas como emocionales. Uno de los principales problemas que se encuentran al tratar con el abuso sexual es que no se ha terminado de identificar los factores psicosociales que se relacionan con la problemática, aunque se ha podido saber que este fenómeno comúnmente se desenvuelve en el entorno familiar de las víctimas. La investigación fue realizada mediante el uso de varias herramientas de recolección de información, facilitando el análisis y organización de la misma, mediante el empleo de una metodología cualitativa que permite la observación, comprensión y descripción objetiva de la problemática antes mencionada.

Authors: Srivastava Sujata , Mistry Hemendra S.
Published: February 2023

India being a democratic country, through Article 14 and 15 of its constitution provides equal opportunity to every citizen to grow and attain their potential irrespective of caste, creed, religion or gender. Despite this constitutional guarantee, the transgender community remained most deprived among the disadvantaged sections of the Indian society. They are still not accepted in the mainstream society; get fewer opportunities for their education and very small numbers have access to higher education. This study conducted through a focus group discussion systematically explores the problems and expectations of transgenders in higher education. The qualitative study was conducted in Vadodara city of Gujarat among transgenders who had higher education opportunities. Themes such as admission, institutional climate, curriculum, financial constraint and availability of resources were highlighted as major aspects that needed attention for the education of transgenders. The results reflect a discriminatory attitude, non-implementation of reservation policies, negative institutional climate, lack of support, lack of transgender sensitive curriculum, financial difficulties and inadequate availability of resources. The study discusses these problems in the line of transgender policies and literature and concludes with the suggestions for policy makers and stakeholders involved in the education of transgenders.

Published: February 2023

Energy harvesting system is using ambient energy conversion in the environment. The environmental energy will be converted into usable electrical energy that can be used in controlling wireless electronic devices. The available mechanical vibration from the sound energy will then be converted to electrical energy by using a piezoelectric transducer. The size of the piezoelectric represents the surface area of the electrode on the piezoelectric model. A smaller size piezoelectric transducer is unable to produce a good vibration due to the smaller surface area. The bigger dimension of the piezoelectric model would be able to harvest more electrical energy output because the vibration from the bigger piezoelectric model which would able to produce more sound wave energy. The piezoelectric material Lead Zirconate Titanate (PZT-5H) vibration is focused on the resonance frequency at below 1 kHz with sound level decibel is between the range of 35-100 dB. This research is to concentrate on rectangular and trapezium-shaped cantilever. The trapezium shaped cantilever produces higher energy output due to its shape which has better in terms of stress and strain distribution. In addition, researchers have modelled and validated energy harvesters with different proof masses shapes. The improved piezoelectric vibrational energy harvester has a trapezoidal beam and an added triangular proof mass. The arrangement of the piezoelectric tested in parallel, series, combination series and parallel configuration to investigate the performance of the output power generated from the sound wave. The rectangular and trapezium shaped cantilever are resulted in a resonant frequency of 269.4 Hz and 269.88 Hz, respectively. The rectangular and trapezium shaped cantilever produced a maximum output voltage of 3.105 V and 3.635 V respectively. The piezoelectric output during the parallel array configuration, which is 5.636 V, 0.497 mA and 2.803 mW. The output power produced by parallel is 81 % higher than compare in series array configuration and 35.8 % higher than combination of series and parallel. Thus, the produced energy output 5 V would be able to apply at several low power supply applications such as mobile phones, power bank or wireless sensor networks (WSN).

Authors: Kim Dong-Lim , Lee Seung-Eun , Kim Nan Hee
Published: February 2023

Chronic kidney disease (CKD) is the most common cause of end-stage renal disease in patients with type 2 diabetes mellitus (T2DM). CKD increases the risk of cardiovascular diseases; therefore, its prevention and treatment are important. The prevention of diabetic kidney disease (DKD) can be achieved through intensive glycemic control and blood pressure management. Additionally, DKD treatment aims to reduce albuminuria and improve kidney function. In patients with T2DM, renin-angiotensin-aldosterone system inhibitors, sodium glucose cotransporter 2 inhibitors, and glucagon-like peptide-1 receptor agonists can delay the progression of DKD. Hence, there is a need for novel treatments that can effectively suppress DKD progression. Finerenone is a first-in-class nonsteroidal mineralocorticoid receptor antagonist with clinically proven efficacy in improving albuminuria, estimated glomerular filtration rate, and risk of cardiovascular events in early and advanced DKD. Therefore, finerenone is a promising treatment option to delay DKD progression. This article reviews the mechanism of renal effects and major clinical outcomes of finerenone in DKD.

Published: February 2023

The study investigated the impact of displacements on the rights of the people that were caused by a development project in Zimbabwe. A case study of people displaced by the construction of the Tokwe-Mukosi Dam was used to explore the challenges faced by displaced people. This study was a mixed-method design. Data was collected using questionnaires and a document. A purposive sample of 100 participants was used by the researchers. The sample comprises people displaced by the construction of the Tokwe-Mukosi dam. The researchers utilised thematic analysis and descriptive statistics to make sense of the data. It was noted from the findings that the livelihoods of the displaced people by the Tokwe-Mukosi changed due to the displacement. Market gardening, a major livelihood among the participants before displacement, was the most affected due to the lack of reliable water sources at the relocation site. Human rights violations were also noted in the study due to the failure of the government to prepare the relocation site adequately. Due to the noted human rights violation, the displaced people were subjected to social distress. Therefore, the study concludes that several communities were negatively impacted by the construction of the Tokwe-Mukosi Dam, with a recommendation that suitable relocation sites with adequate social service should be identified before the finalisation of the construction of dams.

Published: February 2023

Hyperlipidaemia is a disorder characterised by elevated levels of lipid in blood and is frequently regarded as one of the main risk factors for atherosclerotic illnesses, including coronary heart disease. The associated risk factors include obesity, sedentary lifestyle, fatty food intake, excessive alcoholism and smoking. Since hyperlipidaemia has few or no significant clinical signs, a lipid panel or lipid profile analysis constitutes as the primary method of diagnosis. A case of 51-year-old male suffering from Hyperlipidaemia for few years, which was temporarily relieved with conventional treatment, has been presented here. Clinically patient reported with pain in calves, burning feet, dyspepsia and occasional arthritic pain. After a thorough clinical evaluation, Lycopodium Clavatum in increasing potency (up to Q5), was prescribed when needed. The outcome assessment was done by using the ‘Modified Naranjo Criteria’. This case report demonstrates improvement of symptoms as well as the reduction of serum cholesterol and triglycerides with individualised homoeopathic treatment.

Published: February 2023

We present the results of the low-mass X-ray binary 4U 1636–536 study. We performed a temporal analysis of all available RXTE/All-Sky Monitor, RXTE/Proportional Counter Array, Swift/Burst Alert Telescope, and MAXI data collected until the middle of 2022. Within our analysis we confirmed the previously discovered quasiperiodicity of ≃45 days present during ∼2004, and we found that it continued until 2007. Moreover, we showed that similar periodicity also appeared in 2010 and 2011. At other epochs, the quasiperiodicity is only transient. We applied a time-dependent accretion disk model to the interval with the most significant X-ray quasiperiodicity. Although 4U 1636–536 is persistent, the observed quasiperiodicity can be well modeled by the hydrogen thermal-ionization instability occurring in the outer regions of the accretion disk. For our best model, the theoretical light curve’s period and amplitude agree well with those observed.
A Unified Model for Bipolar Outflows from Young Stars: Kinematic Signatures of Jets, Winds, and Their Magnetic Interplay with the Ambient Toroids
Authors: Shang 尚 Hsien 賢 , Liu 劉 Chun-Fan 君帆 , Krasnopolsky Ruben , Wang 王 Liang-Yao 亮堯
Published: February 2023

Kinematic signatures of the jet, winds, multicavities, and episodic shells arising in the unified model of bipolar outflows developed in Shang et al. (Paper I), in which an outflow forms by radially directed, wide-angle toroidally magnetized winds interacting with magnetized isothermal toroids, are extracted in the form of position–velocity diagrams. Elongated outflow lobes, driven by magnetized winds and their interplay with the environment, are dominated by extended bubble structures with mixing layers beyond the conventional thin-shell models. The axial cylindrically stratified density jet carries a broad profile near the base, across the projected velocity of the wide-angle wind, and narrows down along the axis with the collimated flow. The reverse shock encloses the magnetized free wind, forms an innermost cavity, and deflects the flow pattern. Shear, Kelvin–Helmholtz instabilities, and pseudopulses add fine and distinctive features between the jet–shell components, and the fluctuating jet velocities. The broad webbed velocity features connect the extremely high and the low velocities across the multicavities, mimicking nested outflowing slower-wind components. Rings and ovals in the perpendicular cuts trace multicavities at different heights, and the compressed ambient gap regions enrich the low-velocity features with protruding spikes. Our kinematic signatures capture the observed systematics of the high-, intermediate-, and low-velocity components from Class 0 to II jet–outflow systems in molecular and atomic lines. The nested shells observed in HH 212, HH 30, and DG Tau B are naturally explained. Outflows as bubbles are ubiquitous and form an inevitable integrative outcome of the interaction between wind and ambient media.
Surface Reaction of Methyl Mercaptan (CH3SH) with Hydrogen Atoms on Amorphous Solid Water
Authors: Nguyen Thanh , Oba Yasuhiro , Sameera W. M. C. , Furuya Kenji , Kouchi Akira , Watanabe Naoki
Published: February 2023

Methyl mercaptan (CH3SH) is one of the S-bearing organic compounds found in the interstellar medium (ISM). In this study, we investigated the surface reactions of solid CH3SH with H atoms on amorphous solid water using experimental and computational methods to examine their physicochemical behavior in the ISM. Consequently, the primary product was discovered to be CH4. As the computational studies show that the dominant reaction pathway is H + CH3SH → CH3 + H2S, the observed CH4 would result from H addition to CH3. As relatively minor routes, the H abstraction processes from the –CH3 and –SH functional groups of CH3SH, giving rise to CH2SH and CH3S radicals, are confirmed. Although these radicals may form CH3SH again by reactions with H atoms, the loss of CH3SH from the ice surface by chemical desorption would be minor.
Probing Velocity Structures of Protostellar Envelopes: Infalling and Rotating Envelopes within Turbulent Dense Cores
Authors: Sai (Insa Choi) Jinshi , Ohashi Nagayoshi , Yen Hsi-Wei , Maury Anaëlle J. , Maret Sébastien
Published: February 2023

We have observed the three low-mass protostars, IRAS 15398−3359, L1527 IRS, and TMC-1A, with the ALMA 12 m array, the ACA 7 m array, and the IRAM-30 m and APEX telescopes in the C18O J = 2–1 emission. Overall, the C18O emission shows clear velocity gradients at radii of ∼100–1000 au, which likely originate from the rotation of envelopes, while velocity gradients are less clear and velocity structures are more perturbed on scales of ∼1000–10,000 au. IRAS 15398−3359 and L1527 IRS show a break at radii of ∼1200 and ∼1700 au in the radial profile of the peak velocity, respectively. The peak velocity is proportional to r
−1.38 or r
−1.7 within the break radius, which can be interpreted as indicating the rotational motion of the envelope with a degree of contamination by gas motions on larger spatial scales. The peak velocity follows v
peak ∝ r
0.68 or v
peak ∝ r
0.46 outside the break radius, which is similar to the J/M–R relation of dense cores. TMC-1A exhibits a radial profile of the peak velocity that is not consistent with the rotational motion of the envelope nor the J/M–R relation. The origin of the relation of v
peak ∝ r
0.46–r
0.68 is investigated by examining correlations of the velocity deviation (δ
v) and the spatial scale (τ) in the two sources. The obtained spatial correlations, δ
v ∝ τ
∼0.6, are consistent with the scaling law predicted by turbulence models, which may suggest that large-scale velocity structures originate from turbulence.
Compressing the Cosmological Information in One-dimensional Correlations of the Lyman-α Forest
Authors: Pedersen Christian , Font-Ribera Andreu , Gnedin Nickolay Y.
Published: February 2023

Observations of the Lyman-α forest from spectroscopic surveys such as the Baryon Oscillation Spectroscopic Survey or its extension, eBOSS, or the ongoing Dark Energy Spectroscopic Instrument (DESI) survey offer a unique window to study the growth of structure on megaparsec scales. Interpretation of these measurements is a complicated task, requiring hydrodynamical simulations to model and marginalize over the thermal and ionization state of the intergalactic medium. This complexity has limited the use of Lyα clustering measurements in joint cosmological analyses. In this work we show that the cosmological information content of the one-dimensional power spectrum (P
1D) of the Lyman-α forest can be compressed into a simple two-parameter likelihood without any significant loss of constraining power. We simulate P
1D measurements from DESI using hydrodynamical simulations and show that the compressed likelihood is model independent and lossless, recovering unbiased results even in the presence of massive neutrinos or running of the primordial power spectrum.

Published: February 2023

We have performed a systematic study of the rotational, orbital, and X-ray properties of millisecond pulsars (MSPs) in globular clusters (GCs) and compared their nature with those of the MSPs in the Galactic field (GF). We found that GC MSPs generally rotate slower than their counterparts in the GF. Different from the expectation of a simple recycling scenario, no evidence for the correlation between the orbital period and the rotation period can be found in the MSP binaries in GCs. There is also an indication that the surface magnetic field of GC MSPs is stronger than those in the GF. All these suggest dynamical interactions in GCs can alter the evolution of MSPs/their progenitors, which can leave an imprint on their X-ray emission properties. While the MSPs in both GF and GCs have similar distributions of X-ray luminosity and hardness, our sample supports the notion that these two populations follow different relations between the X-ray luminosity and spin-down power. We discuss this in terms of both the pulsar emission model and the observational bias.

We present a near-infrared H-band polarimetric study toward the S235 e2s3 protostar, obtained using the POLICAN instrument on the 2.1 m OAGH telescope. The images reveal a bipolar outflow with a total length of about 0.5 pc. The outflow nebulosity presents a high degree of linear polarization (∼80%) and reveals a centrosymmetric pattern with the polarization position angles. The polarization characteristics suggest their origin to be single scattering associated with dust in the outflow. Using multiwavelength archival data, we performed spectral energy distribution (SED) fitting based on radiative transfer models of turbulent core accretion theory. The best-fit SED model indicated that the protostar has a mass of 6.8 ± 1.2 M

The orientation of the bipolar outflow was found to be parallel to the local magnetic field direction. The overall results assert the fact that the S235 e2s3 source is a massive young star driving a highly collimated bipolar outflow through disk accretion.
The Dynamical Consequences of a Super-Earth in the Solar System
Authors: Kane Stephen R.
Published: February 2023

Placing the architecture of the solar system within the broader context of planetary architectures is one of the primary topics of interest within planetary science. Exoplanet discoveries have revealed a large range of system architectures, many of which differ substantially from the solar system’s model. One particular feature of exoplanet demographics is the relative prevalence of super-Earth planets, for which the solar system lacks a suitable analog, presenting a challenge to modeling their interiors and atmospheres. Here we present the results of a large suite of dynamical simulations that insert a hypothetical planet in the mass range 1–10 M
⊕ within the semimajor axis range 2–4 au, between the orbits of Mars and Jupiter. We show that, although the system dynamics remain largely unaffected when the additional planet is placed near 3 au, Mercury experiences substantial instability when the additional planet lies in the range 3.1–4.0 au, and perturbations to the Martian orbit primarily result when the additional planet lies in the range 2.0–2.7 au. We further show that, although Jupiter and Saturn experience relatively small orbital perturbations, the angular momentum transferred to the ice giants can result in their ejection from the system at key resonance locations of the additional planet. We discuss the implications of these results for the architecture of the inner and outer solar system planets, and for exoplanetary systems.

Published: February 2023

Mucopolysaccharidosis type IIIB (MPS IIIB), also known as Sanfilippo syndrome type B, is a metabolic disease caused by mutations in both alleles of the NAGLU gene encoding for the enzyme α-N-acetylglucosaminidase. A malfunction of this enzyme causes  inability to degrade heparan sulfate, which leads to accumulation of glycosaminoglycans in the cells. MPS IIIB is associated with different symptoms such as neurodegeneration, extreme hyperactivity, sleeping problems, aggressive behavior, reduced fear, and cognitive  deterioration. The condition is by now not curable. Here we describe a patient with MPS IIIB diagnosed at the age of 5 presenting with communication problems, motor dysfunctions, and speech and sleeping problems.

Standard biochemical tests for neurodegenerative disorders and DNA analyses including NAGLU mutation screening were performed. We also did some psychological tests assessing the patient’s communication skills and behavior. 

The patient was heterozygote for two mutations in the gene NAGLU (Y140C and Ser169fs). Thus, he suffered from MPS IIIB due to two mutations in the disease-causing gene.

The patient presented with clear signs and symptoms of MPS IIIB with at least one of the two mutations affecting the α-N-acetylglucosaminidase protein function severely. Here we report the combination of a well-known and previously unreported mutation in the NAGLU gene; this could be dependent on geographical origin of the patient, which needs to be clarified by molecular studies of more MPS IIIB patients from Southeast Europe.

Introduction: The emergence of severe acute respiratory syndrome coronavirus disease (COVID­19) in China at the end of 2019 caused a massive global outbreak that has become a major public health issue.

Aim: Our aim was to investigate the diagnostic potential of chest CT in screening patients suspected of having COVID­19 in high­prevalence settings.

Materials and methods: This is a real­life, prospective, observational study involving 260 patients. All patients received chest CT scan at the emergency department (ED) of Kaspela University Hospital, Plovdiv, Bulgaria and RT­PCR testing for suspected COVID­19 from March 27 to December 31, 2020. COVID­19 likelihood was assessed by assigning each CT scan to a particular category of the COVID­19 Reporting and Data System (CO­RADS). IBM SPSS v. 26 was used to process the data.

Results: The male­to­female distribution ratio was 1.4:1 – 150 (57.7%) males vs. 110 (42.3%) females (p=0.014). The median age was 55 yrs (range 46–65 yrs). Discharged patients were 247 (95.0%), the rest died in the COVID­19 intensive care unit. Males were 4.13 times more likely to be diagnosed with CO­RADS≥3 score than females. Increasing age was associated with an increased likelihood of being classified with higher CO­RADS scores. The ROC curves analysis demonstrated that CO­RADS ≥3 was the optimal cutoff for discrimi­nating between a positive and negative PCR (Youden’s index J=0.67), with an AUC of 0.825 (95% CI 0.72­0.93), sensitivity of 91.9% (95% CI 87.7%­95.1%), specificity of 75.0% (95% CI 53.3%­90.2%) and accuracy of 76.4% (95% CI 70.7%­81.4%).

Conclusions: The results of this study reveal that a CT examination can provide a quick and accurate diagnosis of patients with sus­pected COVID­19 infection, whereas the PCR test is time­consuming, and the delay in receiving results can be substantial when the incidence curve begins to grow rapidly.

Introduction: The number of published biofilm studies and novel ways for studying them has risen dramatically in recent years, ow-ing to the broad application of biofilms in medicine. Some bacteria develop biofilms that are highly resistant to antimicrobial agents, resulting in persistent infections. This necessitates the development of alternative methods for combating biofilms. In this regard, the application of cationic polymers is a good candidate for realization of this strategy. 

Aim: The aim of our study was to investigate the potential of a newly synthesized covalently attached star copolymer of N,N’-dimeth-ylaminoethyl methacrylate and hydroxyl-bearing oligo(ethylene glycol) methacrylate [P(DMAEMA-co-HOEGMA)] to silica surfaces and its quaternized version [P(QDMAEMA-co-HOEGMA)] for destruction of biofilms formed by Bacillus subtilis or Pseudomonas aeruginosa. 

Materials and methods: Model strains representing different genera and taxonomic groups were selected for the study. The anti-biofilm activities of two different newly synthesized cationic polymers were investigated by observation (live/dead staining) of the viability of bacterial cells within the biofilm.

Results: The results obtained by the live/dead labeling of bacterial biofilms show a substantial decrease in the viability of population in the presence of cationic polymers, better expressed at B. subtilis.

Conclusions: The studied two immobilized on silica wafers newly synthesized star copolymers exhibited potential for anti-biofilm effects. The results demonstrated combined potential for reducing the viability of bacterial cells within the biofilms and probably for loosening the biofilm matrix. The effect was better expressed in B. subtilis.

Fixation of humeral shaft fractures is frequently performed with large-fragment (4.5 mm) plates to accommodate immediate weight bearing. Use of small-fragment (3.5 mm) plates as an alternative carries theoretical benefits. We examined nonunion rates and postoperative radial nerve palsy (RNP) rates in a retrospective cohort of patients undergoing open reduction and internal fixation of humeral shaft fractures with 3.5-mm or 4.5-mm plates. Two hundred thirty-six patients with 241 humeral shaft fractures were included. Small 3.5-mm plates were used in 83% of the patients, and large 4.5-mm plates were used in 17% of the patients. Fifty-three percent were made weight bearing as tolerated following surgical fixation. There was a 7% incidence of nonunion and a 10% incidence of RNP in the 3.5-mm plate group. There was a 7% incidence of nonunion and a 15% incidence of RNP in the 4.5-mm plate group. No statistically significant relationship was shown between nonunion or RNP and plate size (P=.74 andP=.39). No relationship was shown between nonunion and postoperative weight-bearing status (P=.45). Subgroup analysis according to plate size additionally showed no association of nonunion with postoperative weight bearing in both the 4.5-mm (P=.55) and the 3.5-mm (P=.25) cohorts. Small-fragment and large-fragment plating of humeral shaft fractures resulted in comparable union and RNP rates, regardless of postoperative weight-bearing status. Our findings suggest that 3.5-mm plate fixation of humeral shaft fractures is a safe alternative to 4.5-mm plate fixation. [Orthopedics. 2023;46(4):198–204.]
