To evaluate the reactive energy release of the Al/Polytetrafluoroethylene (PTFE) mixed powder (Al and PTFE with a mass percentage of 26.5%/73.5%). Based on the traditional formula, three kinds of Al/PTFE test samples with different dosages (4, 6.5, and 9 g) were mixed. By using the self-designed airtight container, and combining with the overpressure sensor, the transient optical fiber pyrometer, and the infrared thermography. The overpressure , the visible light radiation temperature in the closed container, and the infrared light radiant temperature of the container’s outer wall have been obtained by real-time measurements during the process of cooking off, and the reaction products are analyzed by X-ray energy spectrum (EDS) and X- ray diffraction (XRD). The experimental results show that most of the solid products of Al/PTFE powder in the closed container are AlF3 and a small number of intermediate carbon compositions. The released energy during the firing process of the active material Al/PTFE increases with the increase of the mixing amount; The bake-off energy of active material Al/PTFE mixture per unit mass in a closed container is about 10.2 kJ/g, and when the oxygen content in the closed container is sufficient, active material Al/PTFE per unit mass releases more energy.
Children’s non-adultlike interpretations of telic predicates across languages

Published: September 2020

The acquisition literature has documented several different types of misinterpretations of telic sentences by children, yet a comprehensive analysis of these child interpretations has not been attempted and a crosslinguistic perspective is lacking. This task is not easy, for, on the surface, children’s non-adultlike interpretations appear to be scattered and even contradictory across languages. Several cognitive biases have been proposed to explain given patterns (children initially adhere to a Manner bias, or alternatively a Result bias). Reviewing a wide range of studies on the acquisition of telic sentences in relation to tense-aspect markers, we show that children’s non-adultlike interpretations fall into three different patterns. We conclude that the diversity of non-adultlike interpretations that is found across child languages is incompatible with accounts that rely on these cognitive, language-independent principles, but instead is triggered by language-specific properties. Analyzing these patterns in detail, it appears that child learners across languages have problems with tense-aspect forms with variable meanings, in contrast to forms with a one-to-one form/meaning mappings which are acquired earlier. While adults use a context-sensitive interpretation of forms with multiple meanings, various semantic-pragmatic sources can explain children’s difficulties with interpreting such forms. All explanations that we identify across child languages rely on children’s immature command of pragmatic reasoning, albeit in very different ways for the three different patterns. Thus, by taking a crosslinguistic semantic approach and integrating detailed insights from the tense-aspect semantics of specific languages with universal pragmatic effects, we explain the non-adultlike interpretation of telic sentences in a variety of child languages in a comprehensive way.

Published: September 2020

KCl72H2SeO3 and CsCl7H2SeO3 have been synthesized using solution evaporation methods from aqueous solution. Both compounds are monoclinic (P2/n and P21/c) and demonstrate new structure types. One symmetrically unique SeO(OH)2 molecule is present in each structure. SeO(OH)2 molecules via strong hydrogen bonds form chains in KCl72H2SeO3 and layers in ?sCl7H2SeO3. The structures of KCl72H2SeO3 and CsCl7H2SeO3 can be described as consisting of ionic KCl chains and CsCl layers incorporated into the covalent- and hydrogen-bonded H2SeO3 matrix. To the best of our knowledge, the cases when selenious acid acts as a contributor to the molecular building blocks of salt-inclusion structures are not known to date.

Authors: Kumar Deepak , Kumar Suresh
Published: September 2020

The methanol extract and its ethyl acetate fraction (EAF) of Actaea acuminata (Wall. ex. Royle) H. Hara roots were reported to exhibit significant antianxiety, anticonvulsant and antidepressant activities, and mild sedative activity. But the constituents responsible for these activities have not been isolated. The present study was undertaken to isolate neuroprotective compounds of A. acuminata following bioactivity-guided-fractionation. The column chromatography of EAF and its sub-fractions led to the isolation of four phenolic compounds (bergenin, gallic acid, acetyl bergenin and racemic mixture of diacetyl bergenin), which were characterized by IR and NMR spectral analysis. All the compounds exhibited significant antianxiety and antidepressant activities with respect to control. The gallic acid and bergenin did not show anticonvulsant activity, whereas acetyl bergenin and racemic mixture of diacetyl bergenin exhibited significant anticonvulsant activity. Neuropharmacological activities of A. acuminata are attributed due to polyphenolic compounds. Scientific validation of traditional claims of A. acuminata has opened up roadmap of research for the development of CNS affecting lead molecules.

The influence of Pilates exercises on body composition, muscle strength, and gait speed in community-dwelling older women: a randomized controlled trial. J Strength Cond Res 36(8): 2298–2305, 2022—Population aging is a global phenomenon that has wide-ranging consequences for the health of individuals, including age-related obesity, muscle loss, and a decline in muscle strength and gait speed. These alterations are associated with disability, functional decline, and mortality in older adults. The objective of this study was to analyze the effects of Pilates exercises on body composition, handgrip strength, and physical performance among community-dwelling Spanish women aged 60 and older. A randomized controlled trial of a 12-week Pilates training program was conducted. A total of 109 women were randomly allocated to either a control (n = 54) or a Pilates (n = 55) group. Body composition was evaluated by bioelectrical impedance. Body mass index (BMI), percentage of body fat, and height-adjusted skeletal muscle mass index (SMI) were assessed before and immediately after the intervention, as were physical performance, estimated by gait speed (timed up-and-go test), and handgrip strength. Statistically significant improvements (p < 0.05) were observed both within and between groups for handgrip strength (Cohen's d = 0.40 and 0.52 respectively) and gait speed (Cohen's d = 0.86 and 0.87 respectively). After 12 weeks, BMI significantly decreased (Cohen's d = 0.07) only in the Pilates group. No significant differences were observed regarding SMI. In conclusion, a 12-week Pilates exercise intervention on community dwelling women over 60 years old shows beneficial effects on muscle strength, physical performance, and BMI, but failed to induce any changes on body composition.

At the Junction of Clinical and Developmental Science: Associations of Borderline Identity Disturbance Symptoms With Identity Formation Processes in Adolescence
Authors: Campbell Shawna Mastro , Zimmer-Gembeck Melanie , Duffy Amanda
Published: September 2020

Developmental scientists describe the role confusion that can occur for adolescents as they are forming a personal identity. Clinical psychologists describe low self-worth, lack of self-clarity, feelings of emptiness, and dissociation as the key elements of identity disturbance, and they link these to borderline personality disorder. In this study, the authors aimed to work at the juncture of these approaches by considering interrelations between four elements of identity disturbance, typical identity formation processes reflective of identity commitment and confusion, and borderline features. Australian youth (N = 505, 63% female and aged 12–20 years) recruited from clinical and community settings reported on identity commitment, exploration and reconsideration, four elements of identity disturbance, and borderline features. Identity confusion (especially reconsideration) and disturbance were associated with elevated borderline symptoms. Emptiness stood out as the strongest correlate of borderline symptoms. Youth reporting greater emptiness were nearly twice as likely to report a high borderline symptom profile.
Release Mode Dynamically Regulates the RRP Refilling Mechanism at Individual Hippocampal Synapses
Authors: Kim Yujin , Lee Unghwi , Choi Chunghon , Chang Sunghoe
Published: September 2020

Synaptic strength and reliability are determined by the number of vesicles released per action potential and the availability of release-competent vesicles in the readily releasable pool (RRP). Compared with release of a single vesicle (univesicular release), multivesicular release (MVR) would speed up RRP depletion, yet whether the RRP is refilled differently during the two different release modes has not been investigated. Here, we address this question by quantitative optical imaging with an axon-targeting glutamate sensor, iGluSnFRpre. We found that hippocampal synapses preferentially release multiple vesicles per action potential at high extracellular calcium or by paired-pulse stimulation. When MVR prevails, the RRP is recovered very rapidly with a time constant of 430 ms. This rapid recovery is mediated by dynamin-dependent endocytosis followed by direct reuse of retrieved vesicles. Furthermore, our simulation proved that the portion of retrieved vesicles that directly refill the RRP increases dramatically (>70%) in MVR compared with that in univesicular release (<10%). These results suggest that the contribution of rapid and direct recruitment of retrieved vesicle to the RRP changes dynamically with release mode at the level of individual synapses, which suggests a form of presynaptic homeostatic plasticity for reliable synaptic transmission during various synaptic activity.

SIGNIFICANCE STATEMENTThe number of vesicles released in response to an action potential and the number of release competent vesicles in the readily releasable pool (RRP) are the fundamental determinants of synaptic efficacy. Despite its functional advantages, releasing multiple vesicles, especially at small synapses, can deplete the RRP after a couple of action potentials. To prevent failure of synaptic transmission, the RRP should be refilled rapidly, yet whether the RRP replenishment process is regulated by the release mode has not been investigated. Here, using quantitative optical glutamate imaging and simulation, we demonstrate that the contribution of the fast refilling mechanism changes with release mode at the level of individual synapses, suggesting a rapid form of presynaptic homeostatic plasticity during various synaptic activity.

An Analysis of Indonesian Children Repratriation in Syria
Authors: Sasmito Poerwoko Hadi , Harefa Beniharmoni
Published: September 2020

Some Indonesians in refugee camps in Syria state they want to return to Indonesia. The plan to repatriate the Indonesian ex-ISIS then raises the pros and cons. Some consider that Indonesian citizen who have joined ISIS deserve to be given the opportunity to improve themselves and have a right to be returned to Indonesia if they really want to repent. Some are worried that the repatriation of Indonesian citizen who join ISIS would create new problems in Indonesia. The problem is that among them there are dozens of children, and they are not combatants who took up arms against Iraq and Syria. They just follow where their parents go. Using the normative juridical study method, this paper explains the potential impact that can arise on national security if the Indonesian government adopts a policy of repatriating Indonesian children who used to join ISIS. The results in this study then provide a prescription that should be carried out by the Indonesian government towards Indonesian children who used to join ISIS

Published: September 2020

The purpose of this study is to identify the factors that influence environmental disclosure. The study population is 156 companies consisted of companies in the agricultural sector, the consumer goods industry sector, and the basic & chemical industry sector which were listed on the Indonesia Stock Exchange and participated in PROPER 2014-2018. The purposive sampling method was used to determine the research sample in order to obtain 26 company samples or 130 units of analysis. The analysis technique in this study uses multiple linear regression analysis. The results of this study indicate that the level of environmental disclosure in the three corporate sectors in Indonesia is classified as low, due to the absence of standard guidelines for conducting environmental disclosure, so it is still voluntary. The results also show that the variables of board commissioners’ size, size of the audit committee, environmental certification, profitability, and company size have a significant positive effect on environmental disclosure, while leverage has no effect on environmental disclosure. With the low level of corporate environmental disclosure in Indonesia, it is hoped that the government can establish standard, precise, and mandatory guidelines so that companies can further increase information regarding environmental disclosure.

Asthenozoospermia (AS), defined as low-motility spermatozoa in the ejaculate, is a frequent cause of human male infertility. DJ-1 (also known as PARK7), a protein highly associated with male sterility, binds to the mitochondrial complex I subunit to protect mitochondrial function. However, its involvement in spermatogenesis has not been fully elucidated. Previously, the levels of DJ-1 were shown to be significantly decreased in testicular tissues of rats with ornidazole (ORN)-induced AS. Here, we used a rat model to investigate the localization and expression levels of DJ-1 and its interacting NDUFS3 and NDUFA4 mitochondrial complex I subunits, as well as AS-induced metabolic alterations in testicular tissues. ORN significantly reduced the levels of DJ-1 in the nucleus of secondary spermatocytes, while increasing the expression of NDUFS3 in the cytoplasm of primary spermatocytes. Further, NDUFA4 showed higher expression after treatment with ORN. The principal ORN-induced changes in metabolic small molecules related to the accumulation of glucose, glutamine, and N-acetyl aspartate, enhancement of purine pathway, increase of the phosphatidic acid (PA) (18:0/18:1), phosphatidylethanolamine (PE) (16:0/18:1), and PA (18:0/20:4) lipid metabolites, and imbalance in the concentrations of Na+ and K+. However, we did not observe any abnormalities of certain small metabolic molecules and metal ions in semen samples from patients with AS. In conclusion, these results suggest that DJ-1 deficiency in testicular tissues might be closely related to the localization of NDUFS3 and content of NDUFA4, thus causing abnormalities in the mitochondrial energy metabolism and multiple other metabolic pathways.
Modes of Grouping Students, Segregation and Educational Inequalities. A Longitudinal Analysis of a Cohort of Students in Switzerland
Authors: Charmillot Samuel , Felouzis Georges
Published: September 2020

The education system in Geneva, Switzerland, offers two organisationally contrasting modes of grouping students in secondary 1 education. Students either belong to schools which run a segmented system (students are grouped into two streams based on their academic level) or a more integrated system, with heterogeneous classes made up of ability groups for some subjects. Using longitudinal data, this article examines the impact of these two modes of grouping students and of within-school segregation on the way students are oriented in secondary 2 education. The results of a multilevel logistic regression analysis show that students attending the segmented system are less likely to be oriented towards a baccalaureate school, the most selective path of secondary 2 education. They also show that the effects of within-school segregation contribute to reinforcing inequalities between students: the likelihood of attending a baccalaureate school is much lower in classes with a high percentage of students from a disadvantaged background. Finally, they show that the negative effects of school segregation tend to be stronger in the segmented system.
Segregación y Exclusión Escolar de la Primera Generación de Alumnado de Origen Migrante: De la Integración a la Desintegración
Authors: Chamseddine Mohamed
Published: September 2020

Una revisión exhaustiva de las abundantes investigaciones y planes de formación sobre atención de la diversidad cultural, nos remite de forma persistente al concepto integración escolar del alumnado de origen migrante. No obstante, su trayectoria académica desigual y poco alentadora, nos conduce hacia una inexcusable desintegración y exclusión escolar de los mismos. La polarización y segregación escolar, el abandono del Sistema Educativo en Educación Secundaria y la baja tasa de dicho alumnado en la Universidad, confirman la desentonación temeraria producida en las últimas tres décadas, debido a la ausencia de calidad, equidad y eficacia educativa en la gestión de dicha materia. El objetivo de este trabajo es analizar de forma transversal los aspectos pedagógicos e institucionales, asociados a la atención al alumnado migrante, y su vínculo con la segregación y exclusión escolar de los mismos, como son la baja implicación de las familias migrantes en la dinámica escolar, la escasa formación docente, la rotación del profesorado, la ausencia de mediadores interculturales, etc. Todo ello, para impulsar la reflexión sobre posibles respuestas inclusivas, coherentes y contundentes, que garanticen el éxito escolar de la próxima generación. Por tanto, esta cuestión no sólo merece interés académico, sino que se trata de una urgencia moral, política y social.

Published: September 2020

Autonomous self-repairing properties can prolong the service life of materials. In this paper, galactomannan hydrogel with high mechanical strength was prepared by graft copolymerization of galactomannan with acrylamide and octadecyl methacrylate in aqueous solution. The microstructure, water absorption property, self-healing behavior, and mechanical properties of the hydrogels were investigated using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM), etc. The galactomannan hydrogel had the highest tensile strength of 49 KPa and strain of 3000%. The water absorption reached 2340%, and the removal rate of methylene blue was more than 80%. Galactomannan hydrogels demonstrated significant self-healing properties. The cut hydrogel was quite effective in self-repairing in a few minutes, and the self-repairing strength increased with increasing contact time of hydrogel cut surfaces. The healing efficiency of fracture strain could reach 92.7% of the original sample in 10 h. The maximum water absorption of hydrogel reached 2340%. The maximum removal rate of methylene blue by hydrogel reached 80.5%, and the maximum adsorption capacity was 19.3 mg/g. The novelty of the work lies in octadecyl methacrylate being used for galactomannan cross-linking with the ability to self-repair after fracture. The galactomannan self-healing hydrogel has potential in water treatment and sealing technology.

Authors: Martínez-Córdoba Natalia , Espinosa-García Eugenia
Published: September 2020

Introduction: Ataxia-telangiectasia (AT) is a neurodegenerative syndrome with low incidence and prevalence worldwide, which is caused by a mutation of the ATM gene. It is an autosomal recessive disorder that is associated with defective cell regeneration and DNA repair mechanisms. It is characterized by progressive cerebellar ataxia, abnormal eye movements, oculocutaneous telangiectasias and immunodeficiency. Early diagnosis is critical to initiate a timely interdisciplinary treatment, improve acute symptoms, and control the multiple comorbidities of the disease. The following is the case of a patient who presented with the aforementioned characteristics and had an adequate response to the established medical treatment.Case presentation: A 7-year-old female patient from Bogotá, who presented clinical signs of global neurodevelopmental delay, cerebelar ataxia, frequent respiratory infections and ocular telangiectasias. Symptoms were associated with elevation of alpha fetoprotein and immunodeficiency, which allowed for a diagnosis of AT and the initiation of a timely interdisciplinary treatment.Conclusion: AT is a chromosomal instability syndrome with characteristic signs and symptoms. It is essential to know the etiopathogenesis, clinical manifestations, diagnostic criteria, and therapeutic options, emphasizing that early detection and clinical suspicion could favor the proper management of the comorbidities and improve the progressive course of the disease.

Introduction: Chronic venous insufficiency affects about 5% of the global adult population. Venous leg ulcers are one of the most frequent complications of this pathology, with a global prevalence of 2%. This disease affects both the quality of life of patients and, due to the high cost of the treatment, the health system. Compressive therapy and moist wound healing have been the gold standard treatment. However, when complications occur, they may not be effective.Case report: This is the case of a 66-year-old female patient with venous ulcers on her lower limbs and symptoms of fever and local pain that did not respond to conventional therapies. The patient was treated with a new dermal substitute made of an acellular type-I collagen membrane, which promotes the closure of the ulcer by stimulating the replacement of injured tissue with tissue similar to the healthy one. The condition of the patient improved at 16 weeks, and after 8 months of treatment there was no recurrence of the lesions.Conclusions: Acellular type-I collagen membrane developed by the Tissue Engineering Working Group of the Department of Pharmacy of the Universidad Nacional de Colombia is effective in treating venous ulcers of the lower limbs. Its low cost facilitates the access of the whole population to therapies based on its application.
Laparoscopy for traumatic pancreatitis. Case report

Published: September 2020

Introduction: Traumatic pancreatitis (TP) comprises less than 10% of all abdominal traumas but can reach mortality and morbidity rates of up to 34% and 64%, respectively. The treatment of TP has a conservative approach, followed by minimally invasive procedures and surgery if the evolution is torpid.Case report: A 54-year-old male patient with blunt trauma in right hypochondrium due to a bovine kick developed moderate-severe TP and grade IV pancreatic injury (PI). He underwent laparoscopic surgery twice with adequate clinical evolution. He required antibiotic therapy for 19 days and hospitalization for 29 days, of which 9 were in the ICU.Conclusion: The diagnosis of TP is difficult to achieve due to the retroperitoneal location of the pancreas. The treatment of this condition is usually conservative, preferring clinical management with percutaneous or endoscopic drainage over surgical drainage due to its low morbidity and mortality. The recommended surgical approach to these patients is laparotomy; however, the laparoscopic approach is a therapeutic option to be considered for comprehensive management.
El golpe de Estado en Honduras, 2009: Un caso para el estudio de la mediación internacional
Authors: Sáenz Leandro Ronald , Valenciano Hernández María Stephanie
Published: September 2020

El trabajo examina el proceso de mediación internacional llevado a cabo por el expresidente de Costa Rica, Óscar Arias Sánchez, a raíz de lo acontecido en los días posteriores al golpe de Estado en Honduras, perpetuado el 28 de junio del año 2009. Tiene como objetivo analizar las características del conflicto y enmarcar su intento de gestión como un caso de estudio para la mediación internacional en contextos de paz, lo cual contribuye a discernir sus características y a revisar el papel del mediador dentro de estas coyunturas. Se concluye que la mediación internacional se erige como un área de estudio aún poco desarrollada por la teoría de la resolución alternativa de conflictos (RAC) aplicada en la Ciencia Política, llamando a repensar su papel en la promoción de valores alternativos para el diálogo democrático.
