Fishermen in Wakal Village still water is pot to catch coral fish species. The pot is made from woven bamboo with small hexagonal-shaped cracks. The type of fish that are targeted by the catch usually after being caught in the traps suffer injuries to their bodies as they try to escape through small gaps that are hexagonal. The purpose of this study is to analyze the viability of fish after escaping to the cover net. The data were collected by experimental fishing using four units of pots that were cover net in 20 repetitions. The research was conducted from September to December 2018 in Wakal Village, and Central Maluku Regency. The total number of fish caught is only 2.83% of fish that escape into the net cover. Fish that escaped are divided into 7 species including Plectrypops lima, Pinjalo lewisi, Ephinephelus tauvina, Chaetodon kleini, Centropyge bicolor, Priolepis cincta, Paraluteres prionurus. The cause of fish death is not only assessed from the wounds on the body of the fish when escaping or the wounds resulting from contact with other fish but the stress from the fish itself. The environmental factors that greatly affect the survival of fish when escaping are temperature and salinity. Nelayan di Perairan Desa Wakal menggunakan alat tangkap bubu untuk menangkap ikan karang. Bubu terbuat dari anyaman bambu dengan celah-celah berukuran kecil berbentuk hexagonal. Jenis ikan yang menjadi target tangkapan biasanya setelah tertangkap oleh bubu mengalami luka pada tubuhnya karena berupaya meloloskan diri melalui celah-celah kecil yang berbentuk hexagonal. Luka yang terdapat pada tubuh ikan dapat mengakibatkan kondisi yang buruk bagi kelangsungan hidup. Tujuan dari penelitian ini adalah Menganalisis kelangsungan hidup ikan setelah meloloskan diri ke cover net. Pengumpulan data dilakukan dengan uji coba penangkapan menggunakan 4 unit bubu buton yang dipasang cover net sebanyak 20 kali ulangan. Penelitian dilakukan pada bulan September-Desember 2018 di Desa Wakal, Kabupaten Maluku Tengah. Total jumlah keseluruhan ikan yang tertangkap hanya 2.83% ikan yang meloloskan diri masuk ke dalam cover net. Ikan yang lolos terbagi dalam 7 spesies diantaranya Plectrypops lima, Pinjalo lewisi, Ephinephelus tauvina, Chaetodon kleini, Centropyge bicolor, Priolepis cincta, Paraluteres prionurus. Penyebab kematian ikan bukan saja dinilai dari luka pada tubuh ikan saat meloloskan diri ataupun luka akibat dari kontak dengan ikan lainnya namun stress dari ikan itu sendiri. Adapun faktor-faktor lingkungan yang sangat berpengaruh terhadap kelangsungan hidup ikan saat meloloskan diri yaitu suhu dan salinitas.

Abstract
The use of the historical approach in teaching science has been studied for many years. Many researchers claimed that this approach has the power to improve students’ understanding of the nature of science (NOS) by emphasizing not only the products of science but also the evolution of its ideas. In this paper we will deal with historical stories which were integrated into the science curriculum of primary, middle, and secondary school students from Arab schools in the Israeli Galilee (270 students). Integrating short historical stories in science teaching is a pedagogical approach in which teachers use the chronological story of scientific discoveries and the evolution of scientific ideas in order to render students’ perceptions of the conceptual aspects of science, its processes and contexts more accurately. The stories in this paper refer to discoveries by four scientists: Galvani (the discovery of the electrical current), Fleming (the discovery of penicillin), Archimedes (the discovery of the floating principle), and Kekulé (the discovery of the structure of the benzene ring). At the completion of enacting this curriculum, the students were asked to write their reflections. By reading the students’ reflections we found out that they noticed that certain circumstances must be present in order to enable a scientist to make his discovery.
Scalar linear impulsive Riemann-Liouville fractional differential equations with constant delay-explicit solutions and finite time stability
Authors: Hristova Snezhana G. , Tersian Stepan A. 
Published: July 2020

AbstractRiemann-Liouville fractional differential equations with a constant delay and impulses are studied in this article. The following two cases are considered: the case when the lower limit of the fractional derivative is fixed on the whole interval of consideration and the case when the lower limit of the fractional derivative is changed at any point of impulse. The initial conditions as well as impulsive conditions are defined in an appropriate way for both cases. The explicit solutions are obtained and applied to the study of finite time stability.

Published: July 2020

AbstractIn this work, the influence of pulse frequency on the corrosion resistance of Cu–Zn binary alloy has been investigated by using electrochemical workstation, scanning electron microscope and X-ray diffraction. The results have shown that after the electric pulse treatment, the average grain size in the microstructure of high-zinc binary brass decreased and the corrosion resistance increased. The thickness of dezincification layer decreased from 49.8 to 30.8 µm. The diameter of capacitive reactance arc increased from 741.1 to 2898.0 µm. The corrosion potential increased from −0.2719 to −0.2378 V, and the corrosion current density decreased from 6.3147 × 10−6 to 4.6971 × 10−7 A cm−2 by one magnitude order.

Published: July 2020

AbstractThe former analysis of the structural data in liquid Pb–Te alloys, based on the neutron diffraction measurements for this system, was insufficient to obtain the microscopic and spatial configurations in this system. In order to obtain these configurations, we have newly analyzed by using the Reverse Monte Carlo simulations and the method of Voronoi polyhedron. The partial structure factors {S}_{ij}(Q) and thereby {g}_{ij}(r) are newly estimated by using the former data of neutron diffraction measurements, which are now exactly reproduced by the obtained total structure factors S(Q). From these results, it is concluded that the liquid Pb0.5Te0.5 is spatially configured by the mixture of some sorts of covalent-type formation of PbTe molecules and dissociated Pb and/or Te ions with conduction electrons, which result is completely consistent with results of electrical resistivity measurements and also with the thermodynamic analysis.

Published: July 2020

Abstract
High-mobility group box 1 (HMGB1), also called amphoterin, HMG1 and p30, is a highly conserved protein between different species that has various functions in nucleus such as stabilization of nucleosome formation, facilitation of deoxyribonucleic acid (DNA) bending and increasing the DNA transcription, replication and repair. It has also been indicated that HMGB1 acts as a potent pro-inflammatory cytokine with increasing concentrations in acute and chronic inflammatory diseases. Asthma is a common chronic respiratory disease associated with high morbidity and mortality rates. One central characteristic in its pathogenesis is airway inflammation. Considering the inflammatory role of HMGB1 and importance of inflammation in asthma pathogenesis, a better understanding of this protein is vital. This review describes the structure, cell surface receptors, signaling pathways and intracellular and extracellular functions of HMGB1, but also focuses on its inflammatory role in asthma. Moreover, this manuscript reviews experimental and clinical studies that investigated the pathologic role of HMGB1.
Bacopa monnieri alleviates aluminium chloride-induced anxiety by regulating plasma corticosterone level in Wistar rats
Authors: Murugaiyan Senthil Murugan , Bhargavan Rajesh 
Published: July 2020

Abstract

Objectives
Aluminium is present in food preparations, antacids and many medications. It causes neurodegeneration thereby resulting in a spectrum of neurological disorders such as dementia, Alzheimer’s disease and anxiety. Bacopa monnieri (BM) is widely used in ayurvedic medicine to improve memory functions. Its anxiolytic property was investigated in this study by using elevated plus maze (EPM) and plasma corticosterone level.

Methods
Thirty rats were assigned into five groups. Control group received distilled water, and 0.5% tween 80, AlCl3 group received Aluminium Chloride (AlCl3), Protective groups (BM100 + AlCl3 group and BM200 + AlCl3 group) received AlCl3 and BM at two different doses, and the BM200 group received BM. The EPM experiment was performed at the end of the 4th week of oral administration of BM and AlCl3 followed by the measurement of plasma corticosterone.

Results
Oral administration of AlCl3 to rats increases the levels of anxiety as seen in a decrease in the percentage of entries into the open arms of EPM, an increase in grooming frequency and defecation index. However, the rats in the protective groups shown an increase in the percentage of open arm entries and rearing frequency, and decreased grooming frequency and defecation index. AlCl3 alone treated group showed a significant increase in the plasma corticosterone levels compared to the control group. Whereas the protective groups have shown a significant decrease in the plasma corticosterone levels than the AlCl3 alone treated group.

Conclusions
Hence the BM has potential role in reverting the anxiogenic effect of AlCl3 in the amygdala as it is evident from the plasma corticosterone levels and the EPM parameters of different groups under study.

Abstract

Objectives
Limited data on the evolution of thyroid disorders (TD) in Down syndrome (DS) are available. We characterized the timing, prevalence, and dynamics of TD in patients with DS during a long-term follow-up.

Methods
We retrospectively evaluated 91 children and adolescents with DS (12.5 ± 8.3; follow-up 7.5 ± 6.2). Children were monitored at birth, 6, and 12 months of age and twice a year thereafter. Thyroid status and autoimmunity were periodically investigated.

Results
TD were detected in 73.6% of patients, in particular congenital hypothyroidism (CH), autoimmune thyroid diseases (ATD) and subclinical hypothyroidism (SH) were recorded in 16.4, 31.8, and 25.3%, respectively. CH was diagnosed at newborn screening in 86.7% of cases and in the first 6 months of life in the remaining 13.3%; the condition was persistent in 61.5% of patients. In more than 30% of CH cases, glandular hypoplasia was also revealed. In the ATD group, 63.1% of patients with Hashimoto’s disease (HD, 82.6%) were treated with levothyroxine and subjects with Graves’ Disease (GD, 17.4%) started therapy with methimazole. DS with SH were treated in 42.1% of cases. A thyroid hypogenic echopattern, without autoantibody positivity was identified in 27.6% of SH patients.

Conclusions
The high prevalence and evolution of TD in SD requires frequent monitoring starting in the first months of life. CH can be misdiagnosed at screening. In DS subjects, there is a high prevalence of ATD and non-autoimmune diseases with early antibody-negative phases should not be excluded.

Abstract

Objectives
The main cause of hyperandrogenism in children is congenital adrenal hyperplasia, adrenal and gonadal tumors, polycystic ovary syndrome (PCOs) and Cushing’s disease. In the last 20 years several descriptions of girls with hyperandrogenism and venous porto-systemic shunts appeared in literature.

Case presentation
First case is an eleven and a half-year-old girl, was admitted to Department of Endocrinology because of symptoms of hyperandrogenism. Laboratory tests revealed high serum testosterone, androstenedione, and dehydroepiandrosterone sulfate (DHEAS). The ammonia concentration was also increased. In the abdominal angio-CT scans persistent umbilical vein which connected portal and femoral vein was found. The second case was a seven-year-old boy with symptoms of precocious puberty. Blood tests also revealed high concentration of testosterone, androstenedione, DHEAS and ammonia. Imaging studies showed persistent ductus venosus.

Conclusion
Although pathophysiological relation is not clear, porto-systemic shunts should be considered as a cause of hyperandrogenism of unknown origin in children.

Abstract

Purpose
A model for predicting the prognosis of patients with heart failure with reduced left ventricular ejection fraction (HFrEF) is currently not available. This study aimed to develop an age-biomarker-clinical history prognostic index (ABC-PI) and validate it for the assessment of individual prognosis.

Patients and methods
A total of 5,974 HFrEF patients were enrolled and 1,529 were included in this study after excluding missing values and loss to follow-up. Variables that significantly contributed to prediction of all-cause mortality were assessed by Cox regression and latent trait analysis (LTA) was used to validate discrimination of variables.

Results
After Cox regression, the following seven most significant variables were selected: age, N-terminal pro-B-type natriuretic peptide, renal dysfunction, left ventricular mass index, percutaneous coronary intervention, atrial fibrillation, and New York Heart Association (C-index: 0.801 ± 0.013). After verification by LTA, discrimination of these seven variables was proven. A nomogram was used to form the ABC-PI, and then the total score was set to 100 points. A lower score indicated a higher risk. After verification, the 3-year mortality rate was 34.7% in the high-risk group and only 2.6% in the low-risk group.

Conclusion
Our novel ABC-PI shows a good performance and does not require re-input in the original model. The ABC-PI can be used to effectively and practically predict the prognosis of HFrEF patients.
Language learning through an intersectional lens: Gender, migrant status, and gain in symbolic capital for Syrian refugee women in Turkey
Authors: Rottmann Susan Beth , Nimer Maissam 
Published: July 2020

Abstract
This paper sheds light on Syrian refugee women’s negotiation strategies in language learning classrooms and in their broader social contexts from an intersectional perspective. Drawing on in-depth interviews and focus groups complemented by participatory observation in language classes, we use a post-structuralist approach to examine gendered language socialization. Our research combines an intersectional framework and a Bourdieusian perspective on symbolic capital to show how women perform gender and negotiate their roles in classrooms, within families and vis-à-vis the host society. The findings demonstrate that being a woman and a migrant presents particular challenges in learning language. At the same time, learning language allows for the re-negotiation of gender relations and power dynamics. We find that gender structures women’s access to linguistic resources and interactional opportunities as they perform language under social pressure to conform to prescribed roles as mothers, wives and virtuous, and shy women. Yet, these roles are not static: gender roles are also reconstituted in the process of language learning and gaining symbolic capital.

Abstract
Germanium phosphide (GeP), a rising star of novel two-dimensional (2D) material composed of Group IV–V elements, has been extensively studied and applied in photonics thanks to its broadband optical absorption, strong light–matter interaction and flexible bandgap structure. Here, we show the strong nonlinear optical (NLO) properties of 2D GeP nanoflakes in the broadband range with open-aperture Z-scan technique to explore the performance of 2D GeP microfiber photonic devices (GMPDs) in near-infrared (near-IR) and mid-infrared (mid-IR) ultrafast photonics. Our results suggest that employing the GMPD as an optical device in an erbium-doped fiber laser (EDFL) system results in ultrashort pulses and rogue waves (RWs) at 1.55 μm. Likewise, by the incorporation of GMPD into a thulium-doped fiber laser (TDFL) system, stable ultrashort pulse operation is also achieved at 2.0 μm. We expect these findings to be an excellent GMPD that can be applied in mode-locked fiber lasers to open up new avenues for its development and application in ultrafast photonics.

“We Were Like Slaves, All Women. But We Won’t Come Back.” On the Rebellions Sparked by the Disappearance of the Hacienda in an Afro-Ecuadorian Community
Authors: Morales Troya Ana María 
Published: July 2020

Abstract
In Ecuador, there were rebellions of enslaved men and women who organized to free themselves and improve their living conditions from the beginning of slavery. In the memory of past Afro-descendant workers of cane-producing haciendas in the northern Ecuadorian highlands, the Agrarian Reform of 1964 is associated with “the end of slavery” even though slavery was abolished in 1851. Until the 1960s, working conditions on the hacienda were still regarded by the population as akin to slavery. This article discusses a revolt in the ’60s in the Santa Ana hacienda, now an Afro-Ecuadorian community of the same name. Here, the master’s sexual abuse led to a rebellion by a working adolescent. The rebellion led to an insurrection by the workers who, in addition to fighting for the end of the landlord system and the distribution of land, fought for the dismissal and disappearance of the master. Together, these events redefined ideas of development, of private property, and domestic labor especially by women.

Published: July 2020

Abstract
Group theoretical arguments are used to find the subgroup corresponding to symmetry reduction along a particular irreducible representation of a group. The results are used to guide the search for stationary points on the potential energy surface of hydrated copper(I) ion at the HF/6-31G∗, HF/6-31+G∗, HF/6-311+G∗, MP2/6-31G∗, MP2/6-31+G∗, MP2/6-311+G∗, B3LYP/6-31G∗, B3LYP/6-31+G∗, and B3LYP/6-311+G∗ levels. The better levels give the most stable coordination number of two. The effect of desymmetrization on the Cu-O distances and stretching frequencies has been examined.
Promoting inclusiveness in exoskeleton robotics: Addressing challenges for pediatric access
Authors: Fosch-Villaronga Eduard , Čartolovni Anto , Pierce Robin L. 
Published: July 2020

AbstractPediatric access to exoskeletons lags far behind that of adults. In this article, we promote inclusiveness in exoskeleton robotics by identifying and addressing challenges and barriers to pediatric access to this potentially life-changing technology. We first present available exoskeleton solutions for upper and lower limbs and note the variability in the absence of these. Next, we query the possible reasons for this variability in access, explicitly focusing on children, who constitute a categorically vulnerable population, and also stand to benefit significantly from the use of this technology at this critical point in their physical and emotional growth. We propose the use of a life-based design approach as a way to address some of the design challenges and offer insights toward a resolution regarding market viability and implementation challenges. We conclude that the development of pediatric exoskeletons that allow for and ensure access to health-enhancing technology is a crucial aspect of the responsible provision of health care to all members of society. For children, the stakes are particularly high, given that this technology, when used at a critical phase of a child’s development, not only holds out the possibility of improving the quality of life but also can improve the long-term health prospects.
Synthesis, molecular structure and BSA-binding properties of a new binuclear Cd(II) complex based on 2-(1H-tetrazol-1-methyl)-1H-imidazole-4,5-dicarboxylic acid

Abstract
A new binuclear Cd(II) complex, [Cd2(H2tmidc)4(H2O)2]·6H2O (1) based on 2-(1H-tetrazol-1-methyl)-1H-imidazole-4,5-dicarboxylic acid (H3tmidc) has been synthesized and structurally characterized. The single-crystal X-ray diffraction analysis has revealed that there are two crystallographically distinct H2tmidc– anions in complex 1, one of which is coordinated to Cd(II) ion in a terminal fashion, while the other acts as a bis-connector linking two Cd(II) cations to form the dinuclear structure. The dimeric units are stabilized by intra-molecular O–H···O hydrogen bonds and π-π stacking interactions and are further connected into a three-dimensional supramolecular architecture through inter-molecular hydrogen bonds and π-π stacking interactions. The interactions of complex 1 with bovine serum albumin (BSA) were analyzed by fluorescence measurements under physiological conditions. The results have indicated that the fluorescence intensity of BSA was decreased considerably upon the addition of complex 1 through a static quenching mechanism. The synchronous fluorescence spectrum suggested that the interaction of complex 1 with BSA affects the conformations of tryptophan and tyrosine residues and thereby has an influence on the conformation of BSA.
