Locating the Social Position of Pakistani Women in Text Books
Authors: Dr. Ikram Badshah  , Dr. Sarfraz Khan  , Muhammad Kamran
Published: March 2021

The curriculum is the most grounded device to transmit and transform the way of life, values, and convictions of the society to the students. At the point the children enter the school, the pictures of the male and female depicted in books, solidify their ideas about gender bias and such gender stereotypes shape the mental framework of the students and leave an everlasting effect on the social outlook of the students. Children develop a certain sense of perception and personality while reading such books. The text, words, and pictures in the books leave a permanent blueprint in their mind and they organize their behavior along the patriarchal line, represented in the books. In the textbooks, male-dominant ideology has been used to construct reality in such a way that serves the interest of men in a society. There is a latent and manifest nexus of power and language which favors the patriarchal values. Gender ideologies apparent in the books are also embedded in children's pictures, mass media, and even clothing. There are also more males characters and heroes than females characters and heroes in the textbooks of Urdu and English. All prominent leaders of the Pakistan movement are males and only one female leader, Fatimah Jinnah, has representation in the books but that too in her capacity as sister of the founder of Pakistan Quaid-i-Azam Muhammad Ali Jinnah.
ЕКСПОРТ ТА ІМПОРТ ЗЕРНОВИХ КУЛЬТУР В УМОВАХ СЬОГОДЕННЯ
Authors: ЄВТУШЕНКО В.В.
Published: March 2021

Мета. Дослідження експорту та імпорту зернових культур у світі та в Україні у реаліях сьогодення та їх значення для розвитку українського ринку.
Методика. Під час проведення досліджень використано методики, основою яких є порівняльний та системний аналіз, методи узагальнення.
Результати. Проведені дослідження свідчать про те, що глобальна пандемія практично не вплинула на світовий ринок зернових культур. Основну частину постачань зернових культур у світі забезпечують найбільші країни-експортери: США, Канада, Австралія, ЄС і Аргентина. В останні роки до цих країн приєдналися Росія, Україна та Казахстан.
Україна в сезоні 2019-2020р.експортувала більше зернових, ніж у минулому маркетинговому році, причому найбільшим вантажовідправником зерна стала компанія «Кернел». Імпортерами українського зерна як і раніше залишилися країни Азії, Африки та Європи, лідером серед яких є Єгипет. Зернові культури за об’ємами реалізації відносяться до другої статті вітчизняного експорту, що в свою чергу сприяє залученню в Україну валютних коштів та позитивно впливає на курс гривні.
Враховуючи масштаби експорту ринок зернових культур може бути характерним зразком для інших ринків сільськогосподарської продукції. При цьому політика держави повинна ґрунтуватися на врахуванні тих глобальних чинників, які виникають в умовах сьогодення. Експорт зерна не повинен створювати ситуацію, яка може вплинути на внутрішній ринок, формування в необхідній кількості внутрішніх резервів, проведення товарних закупівель. Доцільним є створення умов, які сприятимуть розвитку конкурентного середовища на ринку зерна.
Пропонується в перспективі проведення досліджень процедури митного оформлення зернових культур при переміщенні через кордон України.
Практична значимість результатів дослідження полягає у можливості їх використання в процесі розробки та реалізації політики держави в галузі стимулювання постачань за кордон зернової продукції. Доцільним є використання результатів проведеного
аналізу в навчальному процесі для студентів освітньо-професійної програми «Товарознавство та експертиза в митній справі» спеціальності «Підприємництво, торгівля та біржова діяльність».

Published: March 2021

El objetivo fue detectar la resistencia frente a fosfomicina (FOS), colistina (COL) y tigeciclina (TGC) en enterobacterias recuperadas de fuentes superficiales y profundas de agua del Chaco (Argentina). Se incluyeron aislamientos provenientes de muestras de agua de ríos, lagunas y pozos. Se analizaron 70 muestras de agua (40 de origen superficial y 30 subterráneas). Se obtuvieron 106 aislamientos de enterobacterias (68 en fuentes superficiales y 38 en fuentes subterráneas). En aguas superficiales se encontraron 10 (14,7%) aislamientos resistentes a alguno de los antimicrobianos estudiados mientras que en aguas subterráneas resultaron resistentes 3 (7,9%) aislamientos; en total: FOS (8), TGC (1), COL (1), FOS+TGC (2) y FOS+COL (1). El presente es el primer trabajo realizado en nuestro país cuyo foco es la detección de enterobacterias resistentes a FOS, COL y TGC en ambientes acuáticos. El número de aislamientos resistentes encontrados es bajo pero su sola presencia debe alertar sobre el posible pasaje de este tipo de bacterias desde el ambiente al hombre, considerando al agua como un reservorio y medio de transmisión.

Fibre Reinforced Fixed Partial Denture for Periodontally Compromised Anterior Teeth
Authors: Thirugnanam Sriram
Published: March 2021

Aim: To describe a protocol to replace few missing anterior teeth with periodontally compromised abutments.

Background: Due to their lower modulus of elasticity, fibre reinforced composites (FRCs) minimize the stress level at the tooth restoration interface and enable an adjustment of the framework’s mechanical properties by inserting adequate fibre volumes. Direct and semi-direct fabricated FRC Fixed Dental Prosthesis (FDP) now compete successfully with conventional cast metal resin-bonded FDPs.

Case Description: A Fibre Reinforced Composite(FRC) bridge was given to replace missing 31 and 41. The FRC material was bonded from canine to canine (33-43) to ensure the stability of the periodontally compromised abutment teeth by acting as a splint with minimal intervention.

Conclusion: Fiber-reinforced composite restorations reduce the number of appointments and make single visit dentistry possible especially when the abutments are periodontally compromised and require splinting.

Clinical Significance: This case report demonstrates the benefits of splinting periodontally compromised abutment teeth.

Parents of children with special needs suffer from depression and anxiety disorder, as well as chronic insomnia and stress, this is confirmed by the presence of elevated cortisol levels and reduced immunity. In music therapy, rhythmic music and synchronization, especially music with drums, is used as a therapeutic activity capable of influencing mood improvement, stress reduction and relaxation in a therapeutic context, as it can fit into and adapt to many rhythmic complex and coherent ranges in the real world. This is unifying, creating a sense of security and belonging, allows music to be a facilitator of communicative and social interaction processes. The study uses Perceived Stress Scale (PSS), Cohen, et al., 1983), Improvisation Assessment Profile (IAP), Bruscia, 1987, Natural killer (NK) cell blood analysis, stress (cortisol) saliva analysis. The results of the study showed statistically a significant decrease in psychological and physiological stress patterns, improvements in immunity, interpersonal processes as well as intra-musical synchronization between the first and the tenth sessions.

Published: March 2021

Die auch als 3D-Druck bezeichnete additive Fertigung findet zunehmend Verbreitung bei der Herstellung von Prototypen und Werkzeugen sowie industriellen Bauteilen. Daher hat die Bundesanstalt für Arbeitsschutz und Arbeitsmedizin (BAuA) die Exposition von Beschäftigten gegenüber den eingesetzten Stoffen und den z. B. als Zersetzungsprodukte freigesetzten flüchtigen organischen Verbindungen (Volatile Organic Compounds, VOC) näher untersucht [1]. Die Untersuchungen fokussierten sich auf die additive Fertigung mittels Pulverbettverfahren und erfolgten in zehn Betrieben, die überwiegend Metallpulver und in geringerem Umfang auch Kunststoffpulver einsetzten. Es wurden sowohl personengetragene als auch ortsfeste Messungen durchgeführt, deren Schwerpunkt auf der Ermittlung der Exposition gegenüber der einatembaren (E-Staub) und alveolengängigen Staubfraktion (A-Staub) sowie deren Inhaltsstoffen lag. Die Arbeitsplatzgrenzwerte (AGW) für E- und A-Staub wurden mit Ausnahme eines Betriebes, der Kunststoffpulver verarbeitete, stets eingehalten. Bei der Verarbeitung von Metallpulvern kam es hingegen mehrfach zu Überschreitungen der Beurteilungsmaßstäbe (BM) metallischer Legierungsbestandteile in den Staubfraktionen. Basierend auf den Messergebnissen und betrieblichen Bedingungen wurden Empfehlungen abgeleitet, um Tätigkeiten mit Gefahrstoffen in dieser aufstrebenden Fertigungsmethode sicher zu gestalten.

Research by Segalowitz and Freed (2004) focuses on study abroad outcomes such as proficiency gains and improvement in pragmatic skills, however, this has been conducted in higher education and there are only a few studies available directed towards study abroad outcomes in secondary education (Leis, 2015). This quantitative study aims to examine the effects of a short-term study abroad program (SA) on a group of Japanese high school students. It will use three motivation variables: attitudes to learning English, international posture, and second language (L2) anxiety. Additionally, this study employs adapted pre and post surveys conducted with a sample of fourteen high school students who participated in a seven-day study abroad program to Taiwan, these were compared with a control group of nineteen peers enrolled in a similar course. The paired sample t-tests showed no statistically significance differences for the international posture’s experimental condition and control condition and no significant changes were observed in the anxiety experimental condition and control condition.

Authors: Qi Xun , Jiang Qirong , Lv Ying , Yang Sisi , Li Jing , Huang Yuxian , Chen Liang , Zhang Jiming
Published: March 2021

Aim: Several host factors mediating immune response influence susceptibility to Hepatitis B Virus (HBV) infection, ability to clear the virus, and maintenance of a chronic state. Signal Transducer and Activator of Transcription 4 (STAT4) variations are correlated with the risk of developing autoimmune diseases. However, there have been few studies to assess the relationship between STAT4 variations and Hepatitis B surface Antigen (HBsAg) clearance in adults infected with HBV. Our aim was to evaluate the association between genetic variants in STAT4 and HBsAg clearance in a large sample size population. Methods: This case control study included Chronic Hepatitis B (CHB) (n = 1.688), HBsAg Clearance after Treatment (TC) (n = 170), HBV Uninfected (HC) (n = 1.012), and HBsAg Spontaneous Clearance (SC) (n = 1,052) patients. In the CHB group, patients were categorized into four subgroups: the Immune Tolerant (IT), Immune Active (IA), Inactive (IC), and Immune Reactivation (IR) phases, with 97, 855, 198, and 538 patients in each subgroup, respectively. Results: We found that the G allele in STAT4 rs7574865 was more frequent in the CHB and TC groups, compared with the SC group, whereas the STAT4 rs7574865 GG genotype was more frequent in the CHB and TC group, compared with the SC group in the dominant model. However, there was no statistical significance in genotype between TC and CHB, nor between the IT, IA, IC, and IR groups. Conclusions: The prevalence of the minor allele rs7574865 T was higher in subjects with spontaneously cleared HBV infections than in CHB patients.

Published: March 2021

Objective: Obesity-induced Insulin Resistance (IR) is one of the main causes of Type 2 Diabetes Mellitus (T2DM) and accompanies the progression of T2DM. Serum Ferritin has been shown to be associated with IR. Inflammation is also suggested to be involved in IR and pancreatic β-cell dysfunction. However, there is lack of enough evidence concerning the interrelationship between serum Ferritin, inflammation, and IR in the Chinese population with T2DM. In this study, the relationships between serum Ferritin and inflammatory biomarkers with IR in Chinese population were investigated. Methods: This cross-sectional study was conducted with 207 Chinese participants, aged 40-60 years in Tianjin, China. Serum Ferritin, transferrin, and folate were measured by immuno-assay analyzer. The levels of TNF-α, IL-1β, and IL-6 were detected by ELISA. IR was evaluated by Homeostasis model assessment (HOMA) of IR. Correlations were examined by regression analyses. Results: Serum Ferritin level was higher in non-diabetic obese and diabetic group than the non-diabetic lean group. The levels of TNF-α and CRP were significantly higher in the diabetic obese group than non-diabetic and diabetic lean subjects. Serum Ferritin, TNF-α, and CRP were all correlated with BMI. TNF-α correlated with IR and FPI. TNF-α, IL-6, IL-1β, and CRP were all correlated with FPG and HbA1c. Conclusion: In Chinese population, IR had a significant association with TNF-α but not with serum Ferritin. Serum Ferritin, TNF-α, and CRP were all correlated with BMI. Inflammation and glucose metabolism factors (FPG, HbA1c) showed a strong correlation with each other as well as with adiposity.

High-redshift Lyα blobs (LABs) are an enigmatic class of objects that have been the subject of numerous observational and theoretical investigations. It is of particular interest to determine the dominant power sources for their luminosity, as direct emission from H ii regions, cooling gas, and fluorescence due to the presence of active galactic nuclei (AGNs) can all contribute significantly. In this paper, we present the first theoretical model to consider all of these physical processes in an attempt to develop a model for the origin of LABs. This is achieved by combining a series of high-resolution cosmological zoom-in simulations with ionization and Lyα radiative transfer models. We find that massive galaxies display a range of Lyα luminosities and spatial extents (which strongly depend on the limiting surface brightness used) over the course of their lives, though regularly exhibit luminosities and sizes consistent with observed LABs. The model LABs are typically powered from a combination of recombination in star-forming galaxies, as well as cooling emission from gas associated with accretion. When AGNs are included in the model, the fluorescence caused by active galactic nucleus-driven ionization can be a significant contributor to the total Lyα luminosity as well. Within our modeled mass range, there are no obvious threshold physical properties that predict the appearance of LABs, and only weak correlations of the luminosity with the physical properties of the host galaxy. This is because the emergent Lyα luminosity from a system is a complex function of the gas temperature, ionization state, and Lyα escape fraction.
Afterglow Constraints on the Viewing Angle of Binary Neutron Star Mergers and Determination of the Hubble Constant
Authors: Nakar Ehud , Piran Tsvi
Published: March 2021

One of the key properties of any binary is its viewing angle (i.e., inclination), θ
obs. In binary neutron star (BNS) mergers it is of special importance due to the role that it plays in the measurement of the Hubble constant, H
0. The opening angle of the jet that these mergers launch, θ

j
, is also of special interest. Following the detection of the first BNS merger, GW170817, there were numerous attempts to estimate these angles using the afterglow light curve, finding a wide range of values. Here we provide a simple formula for the ratio θ
obs/θ

j
based on the afterglow light curve and show that this is the only quantity that can be determined from the light curve alone. Our result explains the inconsistency of the values found by the various studies of GW170817 that were largely driven by the different priors taken in each study. Among the additional information that can be used to estimate θ
obs and θ

j
, the most useful is a VLBI measurement of the afterglow image superluminal motion. An alternative is an identification of the afterglow transition to the subrelativistic phase. These observations are possible only for mergers observed at small viewing angles, whose afterglow is significantly brighter than the detector’s threshold. We discuss the implications of these results to measurements of H
0 using GW observations. We show that while the viewing angle will be measured only in a small fraction of future BNS mergers, it can significantly reduce the uncertainty in H
0 in each one of these events, possibly to a level of 4%–5%.
Flybys, Orbits, Splashback: Subhalos and the Importance of the Halo Boundary
Authors: Diemer Benedikt
Published: March 2021

The classification of dark matter halos as isolated hosts or subhalos is critical for our understanding of structure formation and the galaxy–halo connection. Most commonly, subhalos are defined to reside inside a spherical overdensity boundary such as the virial radius. The resulting host–subhalo relations depend sensitively on the somewhat arbitrary overdensity threshold, but the impact of this dependence is rarely quantified. The recently proposed splashback radius tends to be larger and to include more subhalos than even the largest spherical overdensity boundaries. We systematically investigate the dependence of the subhalo fraction on the radius definition and show that it can vary by factors of unity between different spherical overdensity definitions. Using splashback radii can yet double the abundance of subhalos compared to the virial definition. We also quantify the abundance of flyby (or backsplash) halos, hosts that used to be subhalos in the past. We show that the majority of these objects are mislabeled satellites that are naturally classified as subhalos when we use the splashback radius. We show that the subhalo fraction can be understood as a universal function of only peak height and the slope of the linear power spectrum. We provide a simple fitting function that captures our simulation results to 20% accuracy across a wide range of halo masses, redshifts, and cosmologies. Finally, we demonstrate that splashback radii significantly change our understanding of satellite and flyby galaxies in the Local Group.

Published: March 2021

We aim to understand the effect of stellar evolution on the evolution of protoplanetary disks. We focus in particular on the disk evolution around intermediate-mass (IM) stars, which evolve more rapidly than low-mass ones. We numerically solve the long-term evolution of disks around 0.5–5 M
☉ stars considering viscous accretion and photoevaporation (PE) driven by stellar far-ultraviolet (FUV), extreme-ultraviolet (EUV), and X-ray emission. We also take stellar evolution into account and consider the time evolution of the PE rate. We find that the FUV, EUV, and X-ray luminosities of IM stars evolve by orders of magnitude within a few million years, along with the time evolution of stellar structure, stellar effective temperature, or accretion rate. Therefore, the PE rate also evolves with time by orders of magnitude, and we conclude that stellar evolution is crucial for the disk evolution around IM stars.

We present the discovery of a luminous X-ray transient, serendipitously detected by Swift’s X-ray Telescope on 2020 February 5, located in the nucleus of the galaxy SDSS J143359.16+400636.0 at z = 0.099 (luminosity distance D
L = 456 Mpc). The transient was observed to reach a peak luminosity of ∼1044 erg s−1 in the 0.3–10 keV X-ray band, which was ∼20 times more than the peak optical/UV luminosity. Optical, UV, and X-ray light curves from the Zwicky Transient Facility and Swift show a decline in flux from the source consistent with t
−5/3, and observations with NuSTAR and Chandra show a soft X-ray spectrum with photon index Γ = 2.9 ± 0.1. The X-ray/UV properties are inconsistent with well-known active galactic nucleus properties and have more in common with known X-ray tidal disruption events (TDEs), leading us to conclude that it was likely a TDE. The broadband spectral energy distribution can be described well by a disk blackbody model with an inner disk temperature of

K, with a large fraction (>40%) of the disk emission upscattered into the X-ray band. An optical spectrum taken with Keck/LRIS after the X-ray detection reveals LINER line ratios in the host galaxy, suggesting low-level accretion onto the supermassive black hole prior to the event, but no broad lines or other indications of a TDE were seen. The stellar velocity dispersion implies that the mass of the supermassive black hole powering the event is log(M
BH/M
⊙) = 7.41 ± 0.41, and we estimate that at peak the Eddington fraction of this event was ∼50%. This likely TDE was not identified by wide-field optical surveys or optical spectroscopy, indicating that more events like this would be missed without wide-field UV or X-ray surveys.
