Disasters’ impact on supply chains and countermeasure strategies: an overview of the academic literature’ nature
Authors: Brenda de Farias Oliveira Cardoso  , Tharcisio Cotta Fontainha  , Adriana Leiras  
Published: March 2022

Goal: This paper investigates the nature of the academic literature on the disasters’ impacts on Supply Chains (SC) and the strategies adopted to minimize their adverse effects.
Design / Methodology / Approach: Based on a Systematic Literature Review (SLR), we conduct a bibliometric analysis of 129 documents to assess the significant publications’ characteristics regarding year, trend topics, journals, authors, papers more cited, keywords co-occurrence, disasters, SC type, and preliminary identification of disasters’ impacts and countermeasure strategies.
Results: The results show that most studies address natural disasters (e.g., floods, earthquakes, pandemics), and a significant number of documents refer to the food SC. Our findings indicate that the main impacts are: SC instability, supplies shortages, transport and distribution disruption, production and operation disruption, cash flow problems, and productivity reduction; and the main strategies: agility, the collaboration between SC links, organizational flexibility, information sharing, financial and inventory management, digital transformation, government policies, and benchmarking.
Limitations of the investigation: This is a qualitative study with a preliminary examination of the topic through bibliometric results, and for this reason, the content analysis of the documents is outside the scope of the paper.
Practical implications: The findings of this study provide preliminary insights for SC practitioners into the main countermeasures strategies performed to respond to the SC impacts during a disaster.
Originality / Value: The results contribute to a holistic perspective of the topic, which involves the main features of existing studies in the literature.

Published: March 2022

Nematoda penyebab puru akar (Meloidogyne spp.) merupakan parasit penting tanaman budi daya dan memiliki kisaran inang yang luas. Salah satu alternatif pengendalian fitonematoda yang potensial ialah pemanfaatan bakteri non-patogen. Penelitian ini bertujuan mengevaluasi potensi bakteri asal gambut sebagai agens pengendali biologi nematoda puru akar (M. incognita). Pengujian secara in vitro menggunakan filtrat 15 isolat bakteri terhadap M. incognita juvenil 2 (J2) dalam cawan petri. Sebanyak 4.5 mL filtrat bakteri dimasukkan ke dalam cawan petri berdiameter 5 cm, kemudian ditambahkan 50 individu J2 M. incognita dan diinkubasi pada suhu 27 ℃. Pengamatan mortalitas nematoda dilakukan pada 6, 12, dan 24 jam setelah perlakuan. Percobaan disusun dalam rancangan acak lengkap dengan 3 ulangan. Peubah yang diamati ialah persentase mortalitas serta lamanya waktu paparan dalam mematikan nematoda. Karakterisasi fisiologis yang dilakukan terhadap isolat bakteri meliputi uji produksi HCN dan enzim kitinase. Hasil penelitian menunjukkan bahwa 9 isolat bakteri yaitu: GA2 GAA1, GT1 GTA7, GT1 GTB3, GT1 GTB4, GT1 GTB6, GT1 GTB7, GT1 GTC2, GT1 GTC4, dan STDHC4 memiliki kemampuan nematisidal dengan mortalitas mencapai 83%–94%. Isolat bakteri GT1 GTB4 dan GT1 GTB7 memiliki homologi 99% dengan Serratia marcescens asal Cina, dan GT1 GTC2 memiliki homologi 99% dengan Streptomyces sp. AT67 asal Korea Selatan. Ketiga isolat tersebut mampu menghasilkan enzim kitinase dengan indeks lisis >1, namun semua isolat tidak ada yang menghasilkan senyawa HCN.
Calcium signaling in prostate cancer cells of increasing malignancy
Authors: Marchetti Carla 
Published: March 2022

Abstract
Calcium signaling controls a large variety of cell functions, including proliferation and apoptosis, and plays a major role in neoplastic transformation. Prostate cancer (PCa) is one of the most common malignancies in men. The transition to castration-resistant prostate cancer (CRPC), a lethal form that is still lacking an effective cure, could be influenced by fine tuning intracellular calcium ([Ca2+]i) homeostasis. This study investigates [Ca2+]i dynamics in metastatic PCa cell lines that mimic the progression of PCa to CRPC: (i) well differentiated LNCaP cells that require androgen for survival, and (ii) poorly differentiated, highly aggressive androgen-insensitive prostate cancer (AIPC) PC3 and DU145 cells. In AIPC cells, ATP induces a fast rise in [Ca2+]i, due to release from intracellular stores and sensitive to phospholipase C inhibitors, while LNCaP cells do not respond to ATP challenge. Moreover, AIPC cells showed a reduced capacity to store Ca2+ in thapsigargin-sensitive stores and limited store-operated calcium entry, with respect to androgen-dependent LNCaP cells. Finally, green tea extract causes [Ca2+]i elevation and inhibits proliferation in PC3 and DU145 cells, but is ineffective in LNCaP cells. The consequences of these differences are discussed and interpreted in this study with reference to previously proposed models for Ca2+ dependence of prostate carcinogenesis.

Abstract

Objectives
Neurofilament-light (NfL), glial fibrillary acidic protein (GFAP) and contactin-1 (CNTN1) are blood-based biomarkers that could contribute to monitoring and prediction of disease and treatment outcomes in neurological diseases. Pre-analytical sample handling might affect results, which could be disease-dependent. We tested common handling variations in serum of volunteers as well as in a defined group of patients with multiple sclerosis (pwMS).

Methods
Sample sets from 5 pwMS and 5 volunteers at the outpatient clinic were collected per experiment. We investigated the effect of the following variables: collection tube type, delayed centrifugation, centrifugation temperature, delayed storage after centrifugation and freeze-thawing. NfL and GFAP were measured by Simoa and CNTN1 by Luminex. A median recovery of 90–110% was considered stable.

Results
For most pre-analytical variables, serum NfL and CNTN1 levels remained unaffected. In the total group, NfL levels increased (121%) after 6 h of delay at 2–8 °C until centrifugation, while no significant changes were observed after 24 h delay at room temperature (RT). In pwMS specifically, CNTN1 levels increased from additional freeze-thaw cycles number 2 to 4 (111%–141%), whereas volunteer levels remained stable. GFAP showed good stability for all pre-analytical variables.

Conclusions
Overall, the serum biomarkers tested were relatively unaffected by variations in sample handling. For serum NfL, we recommend storage at RT before centrifugation at 2–8 °C up to 6 h or at RT up to 24 h. For serum CNTN1, we advise a maximum of two freeze-thaw cycles. Our results confirm and expand on recently launched consensus standardized operating procedures.

Published: March 2022

Abstract
The water hammer (WH) phenomenon is one of the most dangerous phenomena in hydraulic systems, especially pipelines, gates, and locks on these lines. There are many analytical solutions to deal with the WH phenomenon, including the treatment of friction losses, but most solutions use linear arithmetic operations, which depart from the actual situation of the WH phenomenon. Also, the methods currently used are most challenging and complex and give imprecise results to treat the mentioned phenomenon. In order to reach a state closer to the situation of losses and stability of the hydraulic system that is close to the actual state, basic partial differential equations were used, taking into account the losses generated in the hydraulic system through mathematical conversion. MATLAB was used to program and solve equations, find mathematical results, draw system diagrams, and simulate a WH wave. Various parameters were investigated to show the stability behavior of the hydraulic system by using state-space Method. So, the effect of the pressure, flow rate, diameter, and fluid type were investigated to calculate the stability of the hydraulic system. The results evaluated showed that the system’s oscillation is less at lower pressure, and the stability period is longer than that at high pressures. In addition, the system needs a longer time to stabilize at the low flow speed due to pressure waves that occur. The stability of the system affected by the WH was examined, and the effect of fluid-specific variables such as velocity, pressure, and type of fluid in addition to the diameter of the pipe and their impact on WH stability was found. The behavior of stability at the WH is nonlinear, and that is why the linear and nonlinear parts of the governing equations of the structure are used to find system through the state-space method through programming and simulation of MATLAB program.

Published: March 2022

Abstract
Research suggests that exposure to natural environments can be beneficial for health, such as reducing physical illness and improving mood and cognitive ability. The potential benefits of nature have come into focus at a time when mental health issues are growing globally. Here, we have selected 24 studies from four databases for meta-analysis to explore the effects of exposure to the natural environment on the anxiety of the human body and summarize the influencing factors on the anxiety relief effect. A random-effect meta-analysis of anxiety state changes before and after exposure to natural environment shows that natural exposure effectively alleviated human anxiety (SMD −1.28, 95% CI: −1.65 to −0.92). The overall quality of the included papers, assessed using the PEDro scale, is considered to vary considerably, but most of the papers are rated between 4 and 7 which is considered fair or good. In addition, we have also investigated the potential moderators of anxiety-relieving effects of the nature. Our results shows that the age and exposure time of the subjects are related to the effect of anxiety relief. The results of the subgroup analysis of moderators prove that compared with the middle-aged people (SMD −0.63, 95% CI: −1.13 to −0.12), young people (SMD −1.50, 95% CI: −1.90 to −1.10) get better anxiety alleviation effect in the natural environment. In terms of exposure time, compared with 0.5–2 h (SMD −0.18, 95% CI: −0.59 to −0.23) and >2 h (SMD −0.84, 95% CI: −1.40 to −0.27) exposure periods, subjects get the maximum anxiety relief benefit when they spent <0.5 h (SMD −1.60, 95% CI: −1.93 to −1.27) in the natural environment. However, the quality of the included studies varies greatly and there is a significant heterogeneity in the meta-analysis. Study location, natural environment type and other moderator factors have no obvious correlation with anxiety-alleviation effect of the nature. A higher quality and more comprehensive study needs to be carried out to find out more moderators about the effects of the natural environment on anxiety alleviation. Further experimental studies should also be conducted to determine the mechanism by which natural exposure reduces anxiety so as to provide strong support for the construction and improvement of healthy natural environment.

Published: March 2022

Abstract
Binary gadolinium trisilicide GdSi3 was prepared by high-pressure high-temperature synthesis at typically 9.5(5) GPa and 870 K before quenching to ambient conditions. At ambient pressure, GdSi3 exhibits an exothermic decomposition at 647(10) K into the thermodynamically stable phases GdSi2–x
and Si, indicating its metastable character. Powder X-ray diffraction data is consistent with the YbSi3-type crystal structure comprising slabs of condensed Si2 dumbbells, which enclose layered arrangements of gadolinium cations. Quantum chemical analysis of the chemical bonding shows, that the framework is formed by silicon dumbbells with homopolar bonds. The magnetic moment of 8.13(8) µ
B is consistent with Gd4f
7 (Gd3+ state) and antiferromagnetic ordering is observed below 64(1) K.

Tips From the Floor: Developing a “Coaching Eye”
Authors: Kraemer William J. , Nitka Mike 
Published: March 2022

ABSTRACT
A strength and conditioning professional gets ready to open the weight room or walk the floor during a training session. Attention is drawn, sometimes unconsciously, to a host of different “checkoffs” needed to optimize the training environment. In this column, we note important points that should be typically addressed by the strength and conditioning professional as “tips from the floor.” Developing a weight room culture for operational procedures and updating with cutting-edge changes is vital for optimal player development and safety.
CONSIDERAÇÕES SOBRE A INSERÇÃO DE TECNOLOGIA SOCIAL EM UMA COOPERATIVA DE CATADORES DE MATERIAIS RECICLÁVEIS SOB A PERSPECTIVA DE COOPERAÇÃO, PRODUTIVIDADE, SAÚDE E MEIO AMBIENTE
Authors: Rocha Dulciléia De Sousa 
Published: March 2022

A geração de resíduos sólidos urbanos (RSU) está intimamente relacionada a fatores históricos, como a Revolução Industrial e ao processo de urbanização das cidades. O crescimento do montante de resíduos nos últimos anos é latente. A principal dificuldade reside no manejo e gerenciamento desses resíduos de maneira ambientalmente correta. Nesse contexto, as cooperativas de catadores de material reciclável são uma solução viável do ponto de vista econômico e ambiental. Elas realizam a triagem, reuso, reciclagem e reinserção em cadeias produtivas. Para fortalecimento dessas organizações, em termos de produtividade e da saúde foi construído um protótipo de um projeto de um “Sistema Modular”, concebido dentro do conceito de tecnologia social aplicável em organizações autogestionárias. O uso e eficácia dessa tecnologia estão atrelados a cooperação, coletividade, e saberes dos envolvidos. Por meio do uso do “Sistema Modular” foi possível tecer uma discussão sobre o processo de trabalho, recursos e as interações nele envolvidos.

Glycerin Suppositories and Enemas in Premature Infants: A Meta-analysis
Authors: Burchard Paul R. , Lay Raymond , Ruffolo Luis I. , Ramazani Suzanne N. , Walton J. Mark , Livingston Michael H. 
Published: March 2022

BACKGROUND AND OBJECTIVES
Premature infants are often given glycerin suppositories or enemas to facilitate meconium evacuation and the transition to enteral feeds. We reviewed the best-available evidence for the use of glycerin suppositories and enemas in premature infants.

METHODS
We searched MEDLINE, Embase, and Cochrane Central for randomized controlled trials (RCTs) of premature infants treated with glycerin suppositories or enemas through January 2022. Studies were screened and data extracted independently and in duplicate. We included RCTs of premature infants &lt;32 weeks gestation and/or birth weight &lt;1500 g who were treated with glycerin suppositories or enemas. Meta-analysis was performed using random effects and reported as relative risk or mean difference.

RESULTS
We identified 6 single-center, RCTs of 389 premature infants treated with glycerin suppositories (n = 207) or enemas (n = 182). Mortality rates ranged from 0% to 17%, and the meta-analysis revealed no differences between treatment groups (P = .86). Active treatment was associated with earlier meconium evacuation (mean, 1.5 days; 95% confidence interval, 3.0 to 0.01; P = .05) but not a faster time to enteral feeds (mean, 0.5 days; P = .48). We identified 1 ongoing trial with a target recruitment of 220 premature infants. The quality of evidence was very low to moderate because of inadequate statistical power and other methodologic issues.

CONCLUSIONS
The use of glycerin suppositories and enemas in premature infants is associated with earlier meconium evacuation, but the clinical significance of this finding is uncertain. Treatment has no definitive effects on mortality, necrotizing enterocolitis, or enteral feeds.
Fiscal sustainability vs tax gap – Evidence from Poland
Authors: Uryszek Tomasz , Klonowska Alina 
Published: March 2022

AbstractThe main goals of the article are to investigate the level of fiscal unsustainability in Poland and estimate the tax gap necessary to stabilize the size of the public debt and to follow a path to fiscal sustainability. It hypothesizes that by closing the tax gaps for value-added tax (VAT) and personal income tax (PIT), Poland can cover most of its current fiscal needs and stabilize the country’s fiscal situation. We estimated a modified version of the equation describing Ponzi games, calculated the primary gap indicator, and conducted cointegration tests for ex-post data on public expenditures and revenues to investigate the actual level of fiscal unsustainability. The research period covers yearly observations between 2003 and 2017. Empirical evidence confirmed our research hypothesis. We found out that closing the tax gap could change the situation dramatically. If the public authorities were able to collect the VAT and PIT that currently go uncollected, Poland could easily embark on the path towards fiscal sustainability.
Children's rights in European education. Dilemmas, challenges and implementation regarding Roma children in selected European countries – An introduction
Authors: Óhidy Andrea , Riddell Sheila , Boutiuc-Kaiser Alina 
Published: March 2022

AbstractThe UN Convention on the Rights of the Child (UNCRC) recently had its 30th anniversary. Emerging from the United Nations General Assembly in 1989, it has since become the most ratified international human rights treaty ever. Most European countries ratified it and are thus obliged to ensure the implementation of children's rights in practice. Operationalizing the UNCRC raises practical, conceptual and ethical issues. For example, questions arise concerning children and young people's competence to make autonomous decisions in different social domains, especially in education. There are also debates about children's involvement in dispute resolution and the extent to which rights must always be associated with redress in order to make them meaningful. Clearly, the relationship between the rights of children and young people on the one hand and those of parents and teachers on the other are particularly salient. In addition, challenges may arise in relation to children from the Roma-minority in educational institutions. Article 28 (1) of the UNCRC stresses that “States Parties recognize the right of the child to education, and with a view to achieving this right progressively and on the basis of equal opportunity”. Nonetheless, Roma students frequently experience multiple forms of discrimination in educational institutions which amplify their existing disadvantage. Across Europe, there have been different rates of progress in terms of incorporating aspects of the UNCRC into domestic law and put them into practice in schools and other education institutions, and in many cases Roma children have yet to experience the benefits of enhanced children's rights.
