Published: November 2021

Effective radioactive wastewater disposal is of great significance to the wide use of nuclear energy. In this work, 4, 4ˊ-[1, 4-phenyl-bis (9, 10-dihydro-9-oxa-10-phosphaphenanthrene-10-yl) dimethyneimino)] diphenol (t-DOPO) was used to modify microcrystalline cellulose microsphere (t-DOPOR) to further enhance it affinity toward U(VI) through radiation method. The t-DOPOR were characterized for structural, morphological, and thermal properties by FTIR, SEM and TGA, which prove that t-DOPO is successfully modified on cellulose. Combination the advantage of cellulose and t-DOPO, t-DOPOR possessed abundant functional group (-OH, -NH and P=O), and exhibited extremely strong affinity toward U(VI) with a maximum adsorption capacity of 51.51 mg/g at pH 3. Particularly, A large distribution, KdU, up to 2.54×104 mL g−1 is found, implying extremely strong affinity toward U(VI) than Ln(III) (La(III), Eu(III), Dy(III), Yb(III)) at the binary system. Dynamic column experiment confirmed that t-DOPOR could separate selectively U(VI) in column experiment. In addition, even in the simulated groundwater trace amount of U(VI) was also eliminated efficiently by t-DOPOR. Lastly, the adsorption mechanism elaborated by XPS analysis was inner-sphere surface complexation between U(VI) and -OH, -NH and P=O groups of t-DOPOR. Overall, the synthesized t-DOPOR may be utilized as a promising adsorbent for separation and remediation of U(VI) from wastewater.

Prognosis of acute lymphoblastic leukemia (ALL) in adults is inferior to children. Hence, ALL is still a challenging disease to be cured in adult population. Aberrant genetic alterations have been observed previously in ALL, while the patterns of differential gene alteration have not much been comprehensively determined in the adult and pediatric ALL on a genome-wide scale. This study was attempted to investigate the biological differences in genomic profiling between the adults and children with ALL, and the relationship between the genomic heterogeneity and prognosis. The results showed the similar common mutation types in two populations but the increased prevalence of genetic alterations in adult ALL. The median number of detected gene mutations was 17 (range: 1–53) per sample in adult ALL and 4.5 (range: 1–19) in pediatric ALL(P<0.001). A significant correlation between the increased number of gene mutations and age was found (R2 = 0.5853, P<0.001). 122 and 53 driver genes were identified in adult and pediatric ALL samples, respectively. The IKZF1, IDH1 and TTN mutations were significantly enriched in adult ALL. The incidence of relapse was 40.0% and 9.6% in the adult and pediatric ALL, respectively(P=0.0003). The overall survival (OS) and relapse free survival (RFS) of adult ALL were poorer than pediatric ALL (P=0.0002, P<0.001, respectively). This genomic landscape enhanced the understanding of the biological differences of ALL between the two populations and provided a clue for novel therapeutic approaches.

Published: November 2021

Background：Although insoles made of various materials and shapes have been developed to improve performance in sport activities, few objective evaluations on their effectiveness have been conducted. We investigated the effect of insoles supporting the cuboid bone and anterior part of the calcaneus in healthy individuals.Methods:The subjects included 18 healthy males and females. They walked in standardized shoes with a flat insole (a flat insole made of polyurethane without an arched shape on the surface) and a functional insole (made of carbon and supporting the cuboid and anterior part of the calcaneus). We used a three-dimensional motion analysis device and a force plate to analyze gait and quantitatively compared the effect of functional insoles.Results:There was no difference in the parameters of gait analysis (walking speed, cadence, step length, stride length) between flat insoles and functional insoles. The functional insoles reduced ankle power without reducing walking ability. A comparison between Group A (n = 7), in which the left-right difference in ankle power was more than 20%, and Group B (n = 11), in which the left-right difference in ankle power was less than 20%, indicated that the use of functional insoles reduces the left-right difference of ankle power in the group with a larger difference in power.Conclusion：We believe that the use of functional insoles reduced ankle power without reducing walking ability and equalized left-right power. It may therefore reduce the burden on the muscles of the unilateral lower limbs and improve sport performance.Trial registration：The medical research ethics review committee for individuals at Gunma University (study number HS2017-229)　Registered 20 febluary 2018, https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000034362

Authors: Soikkeli-Jalonen Anu , Mishina Kaisa , Virtanen Heli , Charalambous Andreas , Haavisto Elina
Published: November 2021

Purpose: The aim of this study was to describe healthcare professionals’ (HCPs) perceptions of the support for family members (FMs) of palliative care cancer patients in specialist palliative inpatient units. Methods: A qualitative descriptive design was applied. The data were collected with focus group interviews and analysed with inductive content analysis.Results: Information sharing was recognised as an essential element of support. Also, emotional support, discussions and additional support were offered. Practices to improve support of FMs included a possibility to allocate recourses to the families, systematic support and strengthening HCPs’ competence in family care. Conclusions: The opportunities to implement support focusing directly on FMs were described as restricted. Organisational resources were limited in inpatient units. HCPs felt that they did not have enough time to spend with FMs, and the facilities were also not always suitable to support FMs’ presence and participation. Therefore, there is a need for systematic support and interventions for FMs that could be implemented in inpatient units by the HCPs as a part of the daily care. Furthermore, additional training for the HCPs in palliative family care is needed.

Background: This study aims to investigate the reliability and validity of the Turkish version of the Brunel Lifestyle Physical Activity Questionnaire (BLPAQ) and examine the cultural adaptation of the questionnaire.Methods: After the translation process, the test-retest reliability of the Turkish version of the questionnaire was analyzed with 24 (31.20±5.0 years old; 50% female) participants (2nd test was done 15 days after the first test). In addition, the validity of the scale was evaluated by the correlation between the BLPAQ and the International Physical Activity Questionnaire Short Form (IPAQ-SF) completed by 113 (30.59±5.40 years old; 63.7% Female) participants.Results: A powerful positive and significant correlation was found between the correlation coefficients of the BLPAQ's PPA and UPA subscales between both tests (respectively r=0.96, p<0.01; r=0.87, p<0.01). The Cronbach's alpha coefficient was found to be 0.77 (quite reliable). The PPA subscale of the BLPAQ was positive with the IPAQ-SF's high-intensity physical activity subscale (r=0.47 p=0.00) and total IPAQ-SF excluding sitting (r=0.50 p=0.00) medium in the direction and low positive correlation with the walking activity subscale (r=0.25 p=0.024). No significant correlation was found between the UPA subdivision of BLPAQ and IPAQ-SF (p>0.05).Conclusion: BLPAQ, adapted into Turkish, is a valid and reliable tool that can be used to determine lifestyle according to physical activity level.

Retail florists in the United States were surveyed from Oct. to Nov. 2020 to document business practices and innovative approaches to marketing, designing, and delivering flowers during Mar. to Sept. 2020 of the coronavirus disease (COVID-19) pandemic. Slightly less than half of the responding florists (45.0%) closed operations for an average of 31 to 60 days (15.6%). City or county COVID-19 restrictions caused 34% to close their storefronts to customers. Nearly all offered no-contact delivery service. Approximately one-third of these florists used social media marketing consisting of still images and video posts, and a similar number offered no-contact shopping options. Two-thirds of the florists made no changes to the way they designed flowers (60.6%). Event-oriented stores reorganized their business models and sought daily work to replace postponed or canceled wedding orders. Three-fourths of the florists who terminated employees because of shutdowns hired or planned to rehire all terminated employees.

Published: November 2021

The present study is designed to study processes occurring during the electrical discharge machining (EDM) of tool steels, the influence of orbiting electrode motion on its accuracy, as well as to justify the application of individual orbiting trajectories and implement these data into production. To that end, a trajectory program was written in machine codes for a Mitsubishi EA-28 die-sinking electrical discharge machine using the CIMCO EDIT software package. Also, a prototype punch and ejector of the blanking die were produced and measured. The standard modes of Mitsubishi EA-28 were used to carry out machining in Blasospark GT 250 dielectric fluid to a roughness of Ra 0.6 in 9 passes. The experiments revealed the influence of electrode geometry on the machining of sharp corners, i.e., the formation of unwanted radii on the workpiece. However, this phenomenon is not observed when the corners are drilled with small diameter holes (0.4–0.6 mm). Depending on the machining process along the inner or outer trajectory, inverse electrode motion is also observed. The production part (punch of the blanking die) was machined using a new orbit adjusted to the geometry of the product. The part was found to be consistent with the requirements and the engineering drawing, thus allowing the assembled die to enter the main production. The results of the performed tests, as well as the study of domestic and foreign experience, were used to develop recommendations on the use of individual orbits in the EDM of tool steels, hard alloys, and other hard-to-machine conductive materials. The method of orbiting motion along a particular trajectory was implemented at Cheboksary Electrical Apparatus Plant (Cheboksary).

Authors: Fomin А. M.
Published: November 2021

Objective: to study the eﬀect of selective plasmadsorption (SPS) on the level of pro-inﬂammatory and anti-inﬂammatory plasma cytokines, markers of liver failure in patients with obstructive jaundice.

Material and Methods. The study was conducted in 23 patients with prolonged obstructive jaundice. The baseline level of total bilirubin ranged from 285 μmol/L to 589 μmol/L. All patients were exposed to selective plasmadsorption before biliodigistic surgery and twice in the early postoperative period. Selective plasmosorption was carried using OctoNova by Asahi Kasei Medical (Japan) with the use of the sorbent based on the Plasorba BR-350 anion exchange resin. In one procedure, about two volumes of circulating plasma were treated.

Results. Initial increase in the level of pro-inﬂammatory TNF-α, IL-1β, IL-6 cytokines as well as anti-inﬂammatory IL-10 cytokine was established.

Following SPS, TNF-α level signifcantly decreased by 42.4% (p < 0.05). The decrease in IL-1β and IL-6 was 38.9% and 34.0%, respectively. The level of IL-10 signifcantly decreased by 30.7% (p < 0.05). A signifcant decrease in the levels of total bilirubin by 39.8 ± 3.8%, conjugated bilirubin (by 38.2%), unconjugated bilirubin (by 32.5%), ALT (by 23.5%), AST (by 37%), and bile acids (by 31.4%) was revealed by the end of the procedure. There were no hemorrhagic complications associated with SPS.

Conclusions. Selective plasmosorption in complex treatment of patients with mechanical jaundice with hepatic insufciency in perioperative period reduces endotoxicosis level not only due to correction of biochemical markers of liver failure but also due to reduction of proinﬂammatory and anti-inﬂammatory cytokines.

The position of the newborn baby's body is the main factor aﬀecting the carbon dioxide stress in the oxygen tent.
Chaos from order: a network analysis of in-fighting before and after El Chapo’s arrest
Authors: Colby Darren
Published: November 2021

The effect of leadership decapitation—the capture or killing of the leader of an armed group—on future violence has been studied with competing conclusions. In Mexico, leadership decapitation has been found to increase violence and in-fighting among drug cartels. However, the causal pathways between leadership decapitation and in-fighting are unclear. In this article, it is hypothesized that leadership decapitation will weaken alliances between armed actors, lead to greater preferential attachment in networks of cartels and militias, and result in greater transitive closure as cartels seek to expand their power. These hypotheses are tested with a stochastic actor oriented model on a network dataset of episodes of infighting among cartels and the militias formed to opposed them between the five years before and after Joaquín, “El Chapo” Guzmán Loera, the former leader of the Sinaloa Cartel, was arrested in 2016. The results show that alliances have virtually no effect on the decision of cartels and militias to fight each other; weaker organizations faced a higher reputational cost after El Chapo’s detention; and post-arrest cartel in-fighting did not increase as a result of uncertainty about the relative balance of power among cartels.

Published: November 2021

Introduction: Recent cases of unethical behavior in organizations indicate the need to carry out empirical research about it. Objective: Determine the existence of a relationship between ethics and leadership, demanded by society and prescribed by various academic theories. Method: For this reason, through the conduction of non-experimental, cross-sectional, quantitative research, it is sought to make a process of falsification of the theoretical proposals in the context of a municipal mayoralty. In the development of the research, the responses of 219 leaders were satisfactorily received, answering questions from two psychometric instruments of wide recognition and academic validity, the Ethics Position Questionnaire and the Multifactor Leadership Questionnaire. They were carried out both through an exploratory data analysis and a confirmatory factor analysis, and a model of structural equations that tested the existence of a relation between the ethical position and the styles of leadership. Results: It was also possible to identify the influence exerted by the different ethical positions in each one of the styles of leadership in a local public administration. Conclusions: These findings facilitate the identification of ethical leadership models in local public organizations and contribute towards the empirical demonstration of the current discussion on the relationship between ethics and leadership in organizations.

Background:

Unsafe abortion remains one of the major public health problems, especially
in developing countries. The objective of this study was to assess the level of knowledge on the
legalization of abortion and the practice of abortion among Nepalese undergraduate female students.

Methods:

An analytical cross-sectional study was conducted among the 490 female students of
Pokhara Valley, Nepal. Study populations from the 10 colleges were selected through purposive
and systematic random sampling. The semi-structured questionnaire was used as a data collection
technique.

Results:

Only 34% of students have a good knowledge of abortion legalization, compared to 42%
who have poor knowledge. While two-thirds of the participants (66.6%) were aware that abortion
is legal in Nepal, only a few were aware of the conditions for legalized safe abortion. During sexual
intercourse, almost half of the participants (51.3%) did not use any form of contraception. Unintended
conception was the primary cause of abortion (53.3%).

Conclusion:

The level of knowledge about the abortion law, safe abortion practice, and utilization
of abortion services were found to be poor. Age of the participant, autonomy level for decision
making, religion, and study background were the associated factors with the level of knowledge
and practice of abortion. Community-based health promotion and awareness programs focusing on
the youth population should be conducted.

Since 2006 Lapindo mudflow caused by natural gas drilling in Sidoarjo. Nowdays the mudflow still can't be stopped, and to prevent it from resident's houses, embankments were built. Eventough the embankments and guardrails has been built but sometimes the mud flowing into resident's houses while its raining or the embankments were subsidence or reep. Severity, the distance between the embankment and the residents' houses is about 500 m. So far, the handling action while embankments ware subsidence is residents report the accidents to related parties, namely PPLS. But the response is too late and take a long time to occur the accident, so the mud has been flow in to resident's houses. because so far it is still completely manual and there is no monitoring system can detect the accident in the embankments. Therefore with monitoring the embankments with vibration and overflow of the lapindo puddle using wirelless sensor network spread over a number of dike-prone points, then its send to smartphone via Blynk. When the accident happend system monitoring aplication will be warning and send message easly via smartphone. So the existence of this monitoring tool can provide a sense of security to the citizens.
