The object of research is block low-temperature installations for obtaining fresh water.
Investigated problem: obtaining fresh water from sea using low-temperature technologies.
Main scientific results: the design is developed and the operating characteristics of the demineralizer for sea water are determined.
The influence of the initial salt content of sea water on the ice formation rate is determined. With an increase in the salinity of 3.5 times, productivity on ice decreases 2.3 times.
The kinetics of the salt content in the freezing solution depends on the initial concentration. With an initial salt content of 6.74 g/l, the process rate is 0.4 g/h, with a salt content of 1 g/l – 0.14 g/h
With an initial salt content of 6.74 g/l, the process of separating wastewater from the ice block is more intensive. The salt content of the first portion of the effluent is 3.2 times higher than the initial concentration of the solution.
A cryoscopic curve was obtained for seawater in the concentration range from 0 to 6.74 g/l.
The area of practical use of the research results: studies of the quality of the obtained water showed that the content of nitrates decreases 5 times, the hardness decreases by 2 mg/dm³. The salt content is reduced from 858 mg/dm³ to 560 mg/dm³.
Plants for the concentration of food liquids by the block freezing method are designed to produce environmentally friendly products that preserve the bioactive complex of raw materials as much as possible with minimal energy consumption.
An innovative technological product: design and operating modes of a block freezing plant for seawater desalination.
Scope of application of the innovative technological product: industrial enterprises, the technological process of which requires small volumes of fresh water; to obtain fresh water on oil platforms in the oceans; small hotels, boarding houses on the seaside.
Laboratory management of perinatal patients with apparently “new” anti-D
Authors: Hannon J.L. , Clarke G. 
Published: May 2021

Abstract
Despite the existence of long-standing, well-organized programs for Rh immune globulin (RhIG) prophylaxis, immune anti-D continues to be detected in the D– perinatal population. Between 2006 and 2008, 91 prenatal patients, found to have a previously unidentified anti-D, were followed up with a survey to their treating physician and with additional serologic testing where possible. The physician survey requested pregnancy and RhIG history information, including recent or distant potential alloimmunizing events, and the physicians were asked their opinion on the likely cause for the anti-D. Based on survey responses, updated RhIG information, and results of follow-up serology, anti-D was determined to be attributable to previously unreported RhIG in 44 of 91 (48.3%) cases and to active immunization (immune anti-D) in 36 of 91 cases (39.6%). A probable cause for alloimmunization was reported in 14 of 52 (26.9%) returned surveys. Anti-D alloimmunization continues to occur in our prenatal population despite a comprehensive approach to RhIG therapy. Observations from this prospective patient management strategy include the need for improved application of guidelines for RhIG administration and improved quality of information provided to laboratories assessing RhIG eligibility. A laboratory process for prospective follow-up when unexpected anti-D is detected in pregnancy is recommended.

Published: May 2021

Abstract This research analyzes the impact of identity politics and Pancasila based peace religiosity on the behavior of religious people in the Special Region of Yogyakarta. Identity politics is used in relation to its negative understanding, while Pancasila-based peace religiosity is understood positively, to contract the two. Using a quantitative approach that involved 635 respondents, the research fi nds that the level in which the behavior of the respondents is indicative of identity politics to be as much as 29.6% and by Pancasila-based peace religiosity, as much as 51.1%. In all this, age and the level of education do not moderate theimpact. However, if the number of respondents who chose to answer one way or another is considered, it is clear that in some cases the majority of respondents affirm identity politics. Thus, even though identity politics do not strongly impact the respondents, the trend to affirm identity politics is spread broadly among them. The respondents are hesitant toaffirmatively stay away from identity politics. This potentially creates problems in society when religious people live with others in public sphere.
Abstrak Penelitian ini mengkaji dampak Politik Identitas dan Religiusitas Perdamaian Berbasis Pancasila terhadap perilaku umat beragama di Daerah Istimewa Yogyakarta. Dalam penelitian ini Politik Identitas sengaja dipahami secara negatif dan Religiusitas Perdamaian Berbasis Pancasila sebagai sesuatu yang positif untuk mengkontraskan keduanya. Dengan menggunakan pendekatan kuantitatif atas 635 orang responden, penelitian ini menemukan bahwa perilaku para responden terdampak oleh Politik Identitas sebesar 29,6% dan oleh Religiusitas Perdamaian Berbasis Pancasila sebesar 51,1%. Dalam semua itu, usia dan tingkat pendidikan responden tidak memoderasi dampak keduanya. Namun, jika jumlah responden yang memilih untuk menjawab satu atau lain hal diperhitungkan, maka ditemukan bahwa dalam beberapa kasus mayoritas responden sebenarnyamengafirmasi Politik Identitas. Jadi meskipun Politik Identitas tidak membawa dampak kuat dalam diri para responden, tetapi kecenderungan mengafi rmasi Politik Identitas menyebar sangat luas di antara mereka. Juga jelas bahwa para responden bersikap ragu-ragu untuk menolak perilaku terkait Politik Identitas. Hal ini potensial menimbulkan masalah dalam kehidupan di masyarakat ketika umat beragama hidup bersama dengan umat beragama lain di ruang publik.

Arthritis and Methods for Attenuating the Toxicity
Authors: Li Yuling , Liu Yifan , Shao Yumeng , Zhang Fengcong , Liu Weidong , Liang Xiaodong , Chen Li 
Published: May 2021

Background:
Rheumatoid arthritis (RA) is a chronic autoimmune disease, which
affects the joints and causes significant pain, impairing patient's quality of life. Strychni semen
showed promising results to treat RA. However, there are increasing safety concerns in using
strychni semen due to its severe toxicity.

Aim and Objective:
The purpose of this review is to provide insight into using Strychni semen as
an alternative medicine to treat RA, as well as to offer a method for the safe application of
Strychni semen through processing and compatibility studies.

Methods:
Publications were retrieved and surveyed from CNKI and PubMed relevant to Strychni
semen for a literature review.

Results:
This article summarized the mechanism of function of strychni semen in treating RA with
its anti-inflammatory, analgesic, and immunomodulatory effect. Commonly used methods to
attenuate the toxicity of Strychni semen were also discussed in this article.

Conclusion:
Strychni semen has a good therapeutic effect on RA, mainly by the modulation of
immunity with anti-inflammatory and analgesic effects. Also, the reported toxicity of strychni
semen can be effectively reduced by processing and compatibility methods. Hence, as an
alternative medicine for RA treatment, strychni semen has a broad prospect.
Seleno-Functionalization of BODIPY Fluorophores Assisted by Oxidative Nucleophilic Hydrogen Substitution
Authors: Cugnasca Beatriz S. , Wodtke Felipe , Santos Alcindo A. Dos 
Published: May 2021

Background:
The most current reported methods of chalcogen insertion into BODIPY’s
nuclei are based on nucleophilic substitution reactions of halogenated derivatives, metal-catalyzed
cross-coupling reactions, or assistance by radical mechanisms. Recent reports describe Oxidative
Nucleophilic Hydrogen Substitution (ONHS) reactions involving the functionalization of BODIPY
nuclei by thiols, but the generalities of the strategy for other chalcogens was not yet demonstrated.
Herein we report our contribution on the selenium-functionalization of BODIPY by ONHS in high
yield.

Objective:
Aryl-Se-functionalization of 2,6-brominated BODIPY’s nuclei by ONHS reaction.

Method:
The procedure consists of a direct reaction of 2,6-brominated BODIPYs with in situ generated
PhSeH in THF, at room temperature, under a nitrogen atmosphere. The corresponding products
were isolated and purified by conventional flash column chromatography. Full structure characterization
was performed by 1H, 13C, 19F, and 77Se NMR and DFT calculation.

Results:
Densely functionalized 2,6-dibrominated/3,5-diseleno-BODIPYs were obtained as corresponding
products, leading to versatile molecular scaffolds. Their structural features were contrary
to those initially expected by the original experimental applied conditions. A mechanistic investigation
was performed to conclude that ONHS reaction is governing the transformation, thereby damaging
the nucleophilic substitution of the halogen atoms.

Conclusion:
To sum up, new densely functionalized BODIPY derivatives were synthesized by a
highly selective, simple, fast, metal-free, and efficient insertion of PhSe- residues into the 3,5-positions,
governed by an Oxidative Nucleophilic Hydrogen Substitution (ONHS) reaction in high
yields. It was observed that the presence of halogen (Br) into the 2,6-positions of the BODIPY core
is mandatory for the ONHS reaction, which is completely inert when the 2,6-hydrogenated analogues
are used in the same experimental conditions.
A Social Media Organizational Productivity Model: Insights From Public Health Professionals
Authors: Dailah Sr Hamad Ghaleb , Naeem Muhammad 
Published: May 2021

Background
Many previous studies have explored socialization-oriented social media (SM), but their reach has been limited to the context of information exchange for common personal interests. This study focuses on work-oriented SM, which can enhance organizational networking and productivity levels in the context of public hospitals.

Objective
This study aims to provide a theoretical framework to explain how the use of SM can enhance the skills of health professionals and levels of organizational productivity in uncertain environments.

Methods
A total of 2 distinct forms of data collection techniques were combined: focus groups and semistructured interviews. Both were conducted with doctors and nurses in Saudi public sector hospitals.

Results
The findings reveal that the use of SM can create professional socialization at the level of the institution, and this can enhance skills, knowledge, decision making, and the overall level of organizational productivity. The increasing use of SM creates collaboration between health experts (particularly endocrinologists and pulmonologists in this case) who arrange video calls to share best practices in terms of medication, diet, and health care plans for patients with multiple diseases. Many of these patients are particularly vulnerable, given the wider context of the current global pandemic.

Conclusions
This study culminates in the Social Media Organizational Productivity model, which provides insights into how SM has increased the accessibility of health professionals through the use of technology. Access to such professionals creates a patient-centric approach and a culture of shared communication for dealing with high-risk patients during the current global pandemic.

Affine Annihilator Finding Algorithm for Boolean Function
Authors: Zelenetsky A. S. , Klyucharev P. G. 
Published: May 2021

So far, there are no efficient algorithms to solve a problem of finding the low degree annihilators for arbitrary Boolean function. In the paper we present a new algorithm to find affine annihilators for an arbitrary Boolean function. We start with considering the identity fg ≡ 0 or the arbitrary Boolean function f and its possible affine annihilator g. We use a special representation of the Boolean function in sum of its sub-functions to reduce degrees of considering functions in previous identity. As a result, we establish equivalence between the identity fg ≡ 0 for Boolean functions of n variables and the system of Boolean equations of n-1 variable.An algorithm for finding the affine annihilators for the arbitrary Boolean function f must find all the affine functions g so that fg ≡ 0. Our algorithm is based on reducing the problem of finding the affine annihilators for the Boolean function f of n to the similar problem for its sub-functions of n-1 variable. The presented algorithm has the following advantages:An input function can be presented in different ways;Output can be also presented in different ways;The algorithm can be effectively parallelized.It should be noted that the result we have obtained is not final and highlights some development directions: first, to study the impact of its input and output on the efficiency of the algorithm of various representations and, second, to use our idea of constructing the algorithm for development of algorithms, which allow finding the 2nd, 3rd, etc. degree annihilators for a specified Boolean function.
