Authors: ZHOU KANG , LUO LI , NA BIN
Published: April 2022

After flame retardant and enhancing treatment, fast-grown poplar face the problem of leaching of pharmacy, which affected the effective permanence of the retard and further use is limited. In this paper, we study the fixed effect of low molecule phenol-formaldehyde (PF) resin on nitrogen and phosphorus (N-P) inorganic flame retardant compositeunder the condition of high relative humidity. The change oflateralsizes and quality of the specimens were emphasized in the experiment. Results reveal that the greater the concentration of flame retardant was,the greater weight gain percentage of the samples was, and the more serious leach was in the test, after the specimen was modified with the flame retardant.When weight gain percentage of the specimens is same, the greater the concentration of PF resin test solution was,better effect of the leachresistant will be obtained with the concentration of PF test solution increased.The PF resin with 25% concentration had the best effect to reduce the leach of N-P inorganic composite retards. From the comparative analysis above, it was advisable to indicate the PF resin with 25% concentration had the best effect to reduce the leach of N-P inorganic composite retards.
THE TACTILE PERCEPTION EVALUATION OF WOOD SURFACE WITH DIFFERENT ROUGHNESS AND SHAPES: A STUDY USING GALVANIC SKIN RESPONSE
Authors: HU QIANWEN , LI XIAOHE , FANG HAI , WAN QIAN
Published: April 2022

By adopting the methods of PAD subjective emotion measurement and galvanic skin response physiological measurement, this study explores the differences in people's tactile perception evaluation of the surfaces of beech materialswith different roughness and shapes. The results show that females prefer beech samples with arc shapes, while males prefer thesamples with rectangle shapes; participants' emotional stability under a higher emotional arousal level can to a certain extentbe maintained due to the beech materials with arc shapes. The tactile perception of males for beech materials has a greater range of emotional arousal than that of females, but the arousal speed of males' emotions is lower than that of females' emotions. Moreover, a better tactile perception experience can be created for participants when theroughness of beech materials is limited within a certain range of conditions, and acertain sense of "anxiousness" will be brought to participants if the surface of beech materials is too rough.
A Systematic Review and Meta-Analysis of Mortality and Kidney Function in Uranium – Exposed Individuals
Authors:   McGovern Medical School, UTHealth, The University of Texas at Houston HSC, Horvit Andrew , Molony Donald
Published: April 2022

Review question / Objective: 1) In humans, how does environmental and/or occupational exposure to uranium affect the risk of mortality due to primary kidney disease compared to unexposed individuals? (2) In humans, how does environmental and/or occupational exposure to uranium affect the risk of developing kidney failure compared to unexposed individuals? Eligibility criteria: We included cohort studies that evaluate the risk of CKD/ESKD due to uranium exposure. We also included cohort studies that evaluate standardized mortality due to all-cause mortality, kidney cancer, chronic kidney disease, diabetes, and cardiovascular disease in humans with exposure to uranium. We also included cross sectional studies that evaluate renal function in humans exposed to uranium via biomarkers and hard clinical measures (such as creatinine clearance) compared to humans with low/no uranium exposure. In order to not include the same cohort multiple times in the statistical analyses, we selected studies that evaluated an outcome of interest for a given cohort for the longest follow-up period. When this was not possible (due to multiple studies using different combinations of cohorts with varying lengths of follow up), the study with the largest study population size was selected.

Primary thyroid lymphoma represents a challenging, multi-disciplinary condition that it may be found in addition to positive antibodies against thyroid. Early recognition is essential for an adequate management. A thyroid nodule but usually the entire goiter may rapidly progress to a voluminous mass causing local compressive symptoms. Most of the patients with primary thyroid lymphoma had a history of Hashimoto thyroiditis. Epidemiologically, primary thyroid lymphoma represents an exceptional entities opposite to papillary or follicular cancer. The first tool of evaluation is ultrasound; in order to appreciate the local and distance invasion, computed tomography is useful. Fine needle aspiration and cell block analysis or biopsy and immunohistochemistry report are essential for adequate diagnostic in order to avoid unnecessary surgery. Diffuse large B-cell lymphoma is the most frequent histological type. Chemotherapy and local radiation represents the elective management. Considering this unusual condition, awareness is the key operative word for different practitioners.

Tumor nerve compressions in the upper limb are relatively rare, usually involving ganglion cysts and benign tumors. We present a case series of five patients with peripheral nerve compression in the upper limb due to tumor or cystic masses- ulnar nerve compression in the Guyon’s tunnel due to a ganglion cyst, large median nerve schwannoma compressing anterior interosseous nerve and median nerve, voluminous lipoma compressing median nerve in the proximal forearm, superficial branch of radial nerve compression by a synovial cyst and elbow region lipoma compressing radial nerve. In the beginning, those benign lesions are asymptomatic but, as they continue to grow adjacent to a peripheral nerve clinical manifestations appear progressively as compressive neuropathies. After a preoperative imagistic analysis, tumor resection with careful dissection, in order to preserve the neurovascular structures, is the elective surgical procedure in order to obtain an optimal functional recovery.

There is an alarming increasing incidence of PBC (premenopausal breast cancer) in countries with high income due to, on one hand, more accessible screening tools and, on the other hand, potential implications of daily lifestyle habits and endocrine disruptors of modern society on terms of facilitating tumor growth. A more severe prognostic is found in females younger than 40 years old at first detection, with advanced disease at diagnostic, and those with tumors displaying specific immunohistochemistry configuration (and associated gene profile) like ER (estrogen receptor) positive or HEGFR2 (human epidermal growth factor receptor) negative. Recently, particular aspects are reported in terms of PBC therapy: the switch from offering aromatase inhibitors/tamoxifen only in post-menopausal females was done to premenopausal subjects in addition to medication that offers ovarian function suppression (OFS) – as an alternative to classical oophorectomy - for 5 years up to 10 years extension depending on protocol and patient’ age at first diagnostic. The main endocrine considerations concerning PBC are: OFS and/or chemotherapy or oophorectomy causing prompt hypogonadism, bone status anomalies due to estrogens deficiency, potential endocrine tumors that are prone to be linked (for instance, a higher risk of cancer in acromegalic patients etc.), cardio-metabolic elements as facilitators of early tumorigenesis, fertility issues on PBC survivals etc. The purpose of the present paper is to introduce several key messages that relate to endocrine implications of PBC starting from a case.

Stem cells are precursor cells capable of self-renew and of generating numerous mature cell types. As the field of human embryonic stem cells harvesting has been put under questionable ethic issues, other sources are under investigation and present tremendous potential: tissue specific progenitor stem cells, mesenchymal stem cells, umbilical cord cells, bone marrow stem cells, and induced pluripotent stem cells. Stem cells interest different departments of regenerative medicine as well as conservative wildlife. Stem cells might be a viable option for the treatment of pathologies such as spinal injuries, cardiovascular disease, diabetes, liver injuries or even osteoarthritis. Scientists are looking forward to developing molecules that can activate tissue specific stem cells, promote stem cells to migrate to the side of tissue injury, and promote their differentiation to tissue specific cells, so that many health issues could have an alternative and efficient treatment and or even be cured.

Promoting and supporting breastfeeding is a global priority and an important intervention for the survival of children. The World Health Organization and the American Academy of Pediatrics recommend exclusive breastfeeding in the first six months of life. This article propose a review of the most important medical and psychological aspects regarding psychological counseling and breastfeeding. We highlighted the results of studies that reflect the importance of breastfeeding and its effects on the baby and mother. This paper is a review based on information from the literature. The analysis was limited to articles and guides in English published between January 1, 2007 - June 1, 2021 on PubMed, ScienceDirect and Google Scholar using the following keywords: breastfeeding, mother-child relationship, psychological counseling, breastfeeding counseling, breastfeeding factors, exclusive breastfeeding. In this review we discuss the medical and psychological characteristics of breastfeeding, factors that determine exclusive breastfeeding and its effects, prenatal breastfeeding counseling and the role of psychological counseling in initiating and maintaining breastfeeding. Psychological counseling and care practices influence the achievement and duration of breastfeeding.

The most frequent eating disorders are anorexia nervosa, binge eating and bulimia nervosa. They are frequently aggravated during pregnancy or postpartum and because they impair the general health and psychosocial functioning of the patients, it is fundamental to be carefully managing these pathologies in a multidisciplinary team. The common association with menstrual irregularities, even with secondary amenorrhea, lead to unplanned pregnancy following the patients’ belief that they are infertile, and this represents a risk factor for both mother and fetus. Carefully attention should be paid in the patients’ assessment due to the concealment behaviors adopted in order to hide the maladaptive patterns or the eventual use of certain potential drugs that are thought to prevent weight gain or an excessive appetite and, moreover, in the postpartum period patient should be carefully investigated for an eventual anxiety or depression syndrome that may arise as a result of the postpartum body shape or weight gain from the pregnancy period.

Surgical intervention can lead to blood loss either through perioperative complications, or through disease severity until surgery. For this reason, mastering the main strategies to improve surgical patients’ hematological status, to reduce transfusion rate, and to correct hemoglobin level represent the state of art in surgical patient management. In the last period, due to COVID-19 pandemic and the blood shortage crisis across hospitals, applying principles meant to reduce blood loss, and therefore the rate of blood transfusion, have become even more important.

Authors: Bisai Kampan , Pati Manoj Kumar , Behera Bijay Kumar
Published: April 2022

Phthalates (diesters of phthalic acid) are widely used as plasticizers and additives in many consumer products. Laboratory animal studies have reported the endocrine-disrupting and reproductive effects of phthalates and human exposure to this class of chemicals is a concern. Several phthalates including DEHP, BBP, DBP and etc. have been recognized as substances of high concern. This study aims to systematically review the literature on effects of exposure to phthalates including ovarian effects, testicular effects, effects on reproductive hormonal level as well as gene level and effects on breeding performances in fishes. Related literature search was done through Scopus, Google Scholar, Pub-Med and the reference lists of previous review articles to identify relevant articles published in each subject area. The inclusion criteria were original research, cross-sectional studies, case-control studies, interventional studies and review articles. The search was limited to English language papers. Finally, this review paper provides all current information on the hazards of various phthalate exposures on fish reproduction. The available data demonstrate that phthalate exposure is associated with reproductive disorders in both male and female fishes. Exposure of phthalates causes alteration in reproductive gene expression level as well hormonal level, changes in gamete quality parameters and also has impacts on spawning performances in both sexes.

We present the open-source Bayesian Atmospheric Radiative Transfer (BART) retrieval package, which produces estimates and uncertainties for an atmosphere’s thermal profile and chemical abundances from observations. Several BART components are also stand-alone packages, including the parallel Multi-Core Markov-chain Monte Carlo (MC3), which implements several Bayesian samplers; a line-by-line radiative-transfer model, transit; a code that calculates Thermochemical Equilibrium Abundances (TEA), and a test suite for verifying radiative-transfer and retrieval codes, BARTTest. The codes are in Python and C. BART and TEA are under a Reproducible Research (RR) license, which requires reviewed-paper authors to publish a compendium of all inputs, codes, and outputs supporting the paper’s scientific claims. BART and TEA produce the compendium’s content. Otherwise, these codes are under permissive open-source terms, as are MC3 and BARTTest, for any purpose. This paper presents an overview of the code, BARTTest, and an application to eclipse data for exoplanet HD 189733b. Appendices address RR methodology for accelerating science, a reporting checklist for retrieval papers, the spectral resolution required for synthetic tests, and a derivation of the effective sample size required to estimate any Bayesian posterior distribution to a given precision, which determines how many iterations to run. Paper II, by Cubillos et al., presents the underlying radiative-transfer scheme and an application to transit data for exoplanet HAT-P-11b. Paper III, by Blecic et al., discusses the initialization and post-processing routines, with an application to eclipse data for exoplanet WASP-43b. We invite the community to use and improve BART and its components at http://GitHub.com/ExOSPORTS/BART/.
The Spatial Distribution and Temperature of Mercury's Potassium Exosphere
Authors: Lierle Patrick , Schmidt Carl , Baumgardner Jeffrey , Moore Luke , Bida Tom , Swindle Ryan
Published: April 2022

Aside from the well-studied sodium doublet, the potassium D lines are the only optical emissions in Mercury's exosphere that are amply bright to contrast with the dayside disk. Measurements of the K exosphere are limited compared to Na, but the K regolith abundance is better constrained, so new insights may help to understand surface–exosphere coupling. We use imaging spectroscopy to map the K brightness over Mercury's evening hemisphere, which shows an enhancement at low to midlatitudes, well equatorward of the Na peak. Both Na and K are brighter in the south, but the ratio between northern and southern hemisphere K emission appears less symmetric than that of Na. The disk-averaged Na/K column density ratio is between 70 and 130. During the same night, the dayside emission was mapped, we used a high-resolution spectrograph to attempt to resolve the Na and K line widths on the nightside. Forward-modeling the alkaline line profiles with hyperfine structure gives Na D1 and D2 line widths of 1114 ± 50 K and 1211 ± 45 K, respectively. D2 may appear hotter solely because its higher opacity adds preferentially to the profile wings. The K line width is surprisingly cold and cannot be easily distinguished from the instrumental line width, even at R = 137,500. Line widths roughly constrain K gas between the surface temperature and 1000 K, making it the coldest metallic constituent of Mercury's exosphere. Although Na and K are chemical analogs and often assumed to have similar properties, the results herein illustrate quite different characteristics between these elements in Mercury's exosphere.
The sheltopusik (Pseudopus apodus) in southwestern Ukraine? Insights from the museum collection
Authors: Oskyrko Oleksandra , Lysenko Roman , Jablonski Daniel
Published: April 2022

We provide data on the historical record of Pseudopus apodus (Anguidae) from Odesa, Ukraine based on the specimen re-discovered in the museum collection of the National Science and Natural History Museum of the National Academy of Sciences of Ukraine in Kyiv (NMNH) in 2021. The data show that the specimen belongs most likely to the nominotypical subspecies, P. a. apodus (Pallas, 1775). We discussed the possible origin of the record and we concluded that the specimen was introduced to Odesa most probably from its native range (Crimea or Caucasus). The uniqueness of the record and the past human-mediated interactions thus suggest an allochthonous origin rather than the historical sign of the relict population. Thus, our data clarify the situation on species distribution in the north-western Black Sea region from where we have still limited knowledge.

Authors: Mignenan Victor
Published: April 2022

Notre article améliore la compréhension du pouvoir explicatif de l’intelligence collective sur la résilience entrepreneuriale, grâce à l’ancrage du management collaboratif. Notre objectif consiste à proposer un modèle de résilience entrepreneuriale en contexte de Covid-19 afin de contribuer efficacement à la relance économique. La collecte des données a été réalisée au moyen de 15 entrevues et 282 enquêtes par sondage auprès des entrepreneurs résilients camerounais et tchadiens. Nos principaux résultats montrent que l’intelligence collective, via ses principales composantes, est une posture et un moyen privilégié qui accroît la résilience entrepreneuriale économique et stratégique à l’ère incertaine, ceci s’explique par le fait que les entrepreneurs qui survivent durant la Covid-19 font recours aux réseaux d’affaires, aux capacités dynamiques et aux élans de solidarité. De ce fait, les entrepreneurs procéderaient à l’instrumentation des constituantes de l’intelligence collective afin d’assurer leur résilience.

The Relational Dimension of Care at the Foundation of the Rights of Pupils With SEN
Authors: Tarantino Giovanni
Published: April 2022

The relational dimension of care becomes the foundation of the rights of pupils with SEN when considering the asymmetry that may exist in the relationship between the teacher and the pupil with special educational needs. This asymmetry can, in fact, find the pupil with vulnerability in an inferior position compared to the teacher. This, by analogy, is the same asymmetry that can also be found in the relationship between doctor and patient. From the awareness of this derives the need for an ethical approach to care (of the pupil with SEN, as well as of the patient), which is identified with that moral attitude of the individual who tries to meet the needs of those with a vulnerability. An ethical approach cannot stop, however, in considering only the medical-biological dimension of the subject with vulnerability. It must also address all the dimensions that make up the nature of the human person.

Sustainable economic growth is a top priority for Oman, aiming to lessen reliance on oil and increase economic diversification. The government sees entrepreneurship and innovation as vital players in creating jobs, diversifying the economy, and transforming the economy from a traditional to a knowledge-based economy. Under the Visions 2020-2040, the government has developed programs to enhance and encourage women's engagement in SMEs to maximize returns, create employment opportunities, and reduce the market and institutional failures. Lack of women engagement in SMEs is due to barriers of entrants and women who intend to start their own business can face challenges that lead to failure in their business endeavors. Among these challenges are government policies, financial support, supporting R&D, and culture. Further research is necessary to investigate factors that motivate Omanis to become entrepreneurs and overcome the obstacles.

This paper investigates the impact of air pollution on China’s internal migration using the Migrant Population Dynamic Monitoring Survey and Air Quality Index (AQI) data in 2014. Binary response models suggest that, on average, the probability of the willingness to leave will grow by approximately 0.1 if the average value of AQI is increased by 100 points. The migration effect of sever air pollution still holds using two-stage least squares estimation. In particular, compared to inter-province and intra-city within the same province, interviewees are more willingness to leave in intra-county with the same city. Besides, individuals from the cities in central and western regions, the listed key environmental protection (KEP) cities and cities not listed as resource-based (RB) cities have stronger willingness to leave than those from the cities in eastern region, Non-KEP cities and RB cities. Our results are robust to alternative measures of air pollution and models specification.

A produtividade sempre foi a principal preocupação das empresas, visto que, antigamente, estas chegavam a negligenciar o bem-estar do trabalhador em troca de melhores resultados. Com o surgimento dos estudos ergonômicos um novo perfil vem sendo adotado por diversas organizações que buscam conciliar o bom desempenho com a qualidade de vida no trabalho. A ergonomia refere-se à adaptação do trabalho ao homem, constituída por uma relação homem-máquina-ambiente, atentando-se à qualidade de vida e ao bem-estar do trabalhador. O estudo realizado na empresa com segmento direcionado ao ramo de confecção têxtil, na fabricação de variados tipos e modelos de calças, situada no interior do Estado de São Paulo (SP), na Região Sudesde, contou com o auxílio do método OWAS, que é uma ferramenta ergonômica que observa, analisa e aponta o grau de risco das determinadas posições dos colaboradores. Tem foco na análise das posições referentes a braços, pernas, costas e do fator força, culminando em uma classificação designada por dígitos que são capazes de indicar qual a situação ergonômica em que o trabalhador está inserido. A partir desta ferramenta de análise postural, foi possível apontar as irregularidades referentes à postura e as possíveis melhoras em relação a elas. A análise realizada na empresa apresentou resultados consideravelmente satisfatórios, pois permitiu identificar as inadequações existentes referentes à questão ergonômica, com isso, possibilitando o processo de apresentação de sugestões que possivelmente irão trazer benefícios para a organização. Por fim, o estudo apontou a necessidade de futuros estudos na área da ergonomia nos demais postos de trabalho.

A poluição aquática causada por efluentes industriais têm afetado de forma diferenciada os diversos ecossistemas e elevado consideravelmente a concentração de poluentes no ambiente, como os metais, que podem ser tóxicos, de difícil tratamento e que não se degradam, tornando-se acumulativos. A busca por medidas alternativas de tratamentos de efluentes de águas residuais tem levado a estudos de métodos utilizando fitorremediação com plantas, fungos e bactérias como formas diferenciadas para remover contaminantes por meio de biossorção/bioacumulação na fase de polimento de tratamentos. Dessa forma, a macrófita aquática Pistia stratiotes foi utilizada como matriz na remoção do íon cromo (VI) em meio aquoso sintético. Observou-se que a concentração do íon (2,5 mg L-1) não inibiu o desenvolvimento da planta e o que ocorreu foi a biossorção/bioacumulação no estudo cinético com taxa de remoção de 98,5%, sendo o sistema ajustado ao modelo cinético de Langmuir Reversível. A técnica de fitorremediação por Pistia stratiotes utilizada neste estudo, pode atenuar concentrações de poluentes se utilizada como polimento em tratamento de efluentes industriais.

Authors: Retamal Facundo Atuel , Rougier Viviana Carolina
Published: April 2022

Foamed cellular concrete (FCC) is a type of lightweight concrete. Traditionally, it has been used for insulation and void filling. However, in the last years, the possibility of obtaining high strength FCC has motivated the study of its structural use. The novelty and uniqueness of this article is to provide a review of the most important aspect of FCC including component materials, design and mix elaboration, physical properties and mainly, its mechanical behaviour. Also, in order to achieve a global understanding of the material and its characteristics, advances regarding its physical properties are collected: density, porosity, thermal, acoustic and water insulation, durability, fire resistance and drying shrinkage. Then mechanical properties such as elastic modulus, compressive, tensile, bending and shear behaviour, are analysed. The literature review also aims to evaluate the influence of using inert and active mineral additions, fibers and chemical additives to improve its mechanical and physical properties. Based on the work done, research needs have been identified: there are no prediction models for stress-strain behaviour with complete curves for FCC in compression nor in traction, the performed numerical modelling is scarce, use and effect of chemical additives is a not far studied, long-term tests are scarce or nil, the evaluation of resistance in different aggressive environments has not been sufficiently evaluated.

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information. Our study compared the associations among different regression models. The participants were recruited from the Center of Reproductive Medicine, The First Hospital of Jilin University (Changchun, China) between June 2018 and June 2019. We used linear, logistic, and quantile regression models to calculate the associations between sex hormone levels and BMI. In total, 448 men were included in this study. The average BMI was 25.7 (standard deviation [s.d.]: 3.7) kg m−2; 29.7% (n = 133) of the participants were normal weight, 45.3% (n = 203) of the participants were overweight, and 23.4% (n = 105) of the participants were obese. The levels of testosterone and estradiol significantly differed among BMI groups (all P < 0.05). In linear regression and logistic regression, BMI was associated with testosterone and estradiol levels (both P < 0.05). In quantile regression, BMI was negatively associated with testosterone levels in all quantiles after adjustment for age (all P < 0.05). BMI was positively associated with estradiol levels in most quantiles (≤80th) after adjustment for age (all P < 0.05). Our study suggested that BMI was one of the influencing factors of testosterone and estradiol. Of note, the quantile regression showed that BMI was associated with estradiol only up to the 80th percentile of estradiol.
