Removal of acid yellow 17 dye from aqueous solutions using activated water hyacinth (Eichhornia crassipes)
Authors: Alemu Agegnehu , Kerie Endalkachew 
Published: June 2022

Abstract
Dye-containing wastewater has been known as a serious environmental treat. There are many treatment methods, but they are not practical in many developing countries. In this study, batch adsorption of acid yellow 17 dye from aqueous solution has been carried out on a laboratory scale using activated water hyacinth root powder. The dye removal efficiency was measured using a UV-Vis spectrometer. Adsorption experiments were carried out in a batch process at different operating parameters including initial dye concentration, adsorbent dose, contact time, and solution pH. From the experimental data, the maximum dye removal efficiency achieved was 92.26% at pH 2, initial dye concentration 50 mg/L, contact time 120 min, and adsorbent dose 20 g/L. Experimental studies indicated pseudo-second-order kinetic (R2 = 1) and Langmuir isotherm (R2 = 0.953) models could better describe acid yellow 17 dye adsorption on the activated water hyacinth. Adsorption experiments revealed that activated water hyacinth prepared from locally available infesting water bodies had a high potential for removing acid yellow 17 dye from aqueous solution.

Authors: Abu-Baker Nesrin N. , Khwaileh Ghufran M. , AlBashtawy Mohammed , Al-Dwaikat Tariq 
Published: June 2022

Background:
Health promotion is a process of enabling people to increase control over and improve their health. Understanding the concept of health promotion and using it in practice is crucial for nurses in primary care settings.

Aims:
To assess attitudes toward health promotion and related demographic variables among nurses in Jordanian primary care settings.

Methods:
A cross-sectional, correlational design was utilized from November 2020 to February 2021. Convenience sampling was used to recruit 145 nurses in primary care settings in northern Jordan. A self-reported questionnaire was distributed to all eligible nurses. It was part of the “nurses’ knowledge and attitudes toward health promotion questionnaire” which was used in a study before.

Results:
Positive attitudes were found with a mean score of 25.26 out of 32 (SD = 2.96). While 87.6% of participants agreed that nurses should assume more responsibility for health promotion, 60.7% agreed that patients found health promotion dull and boring. While 71% claimed to have the necessary skills to conduct health promotion, only 43.4% agreed that they had enough time to conduct health promotion. Furthermore, nurses with a bachelor’s degree had significantly higher attitude scores compared to nurses with an associate degree (t [143] = -2.053, p = .042).

Conclusion:
The value of health promotion should be emphasized early on among nursing students; more time and resources should be devoted to facilitate health promotion in primary settings, and policymakers and administrators should establish clear guidelines and a supportive environment to enhance the nursing role in providing health promotion.
Internet-Based Prevention Program of Victimization for Youth in Care and Care Leavers (EMPOWER YOUTH): Protocol for a Randomized Controlled Trial
Authors: Wagner Birgit , Reuter Laurence , van Noort Betteke Maria 
Published: June 2022

Background
The global estimate of the number of children in institutional care is around 5 million, with around 1 million of these children living in Europe. In Germany, about 75,000 children and adolescents find themselves in the foster care system and about 93,000 additional children and adolescents are living in institutions. Traumatic experiences and neglect in childhood are highly prevalent among these youth in care and are related to severe long-term effects. Childhood maltreatment and abuse can increase the risk of future victimization experiences. Although youth in care are at risk of victimization or revictimization, no specific evidence-based prevention program has been designed to address these specific needs.

Objective
This study aims to evaluate the efficacy of a newly developed 6-module internet-based prevention program of victimization for youth in care, named EMPOWER YOUTH.

Methods
In a randomized controlled trial, the intervention group will be compared to a waiting-list control group with an unblinded 1:1 allocation ratio. Assessments will take place before randomization (baseline) and at follow-up 18 weeks after baseline (ie, 12 weeks after finishing the last module of the program). The primary endpoint is the number of victimization, and online and offline bullying experiences (composite score) at the 18-week follow-up. Secondary endpoints are risk-taking behavior, aggressive tendencies, empathy, prosocial behavior, depressiveness, and loneliness at follow-up. The expected outcome requires a sample size of 156 subjects to achieve a power of 80%. Assuming a 30% dropout rate at follow-up, we require 225 participants to be allocated to the trial. Participants are youth in care, that is, adolescents in foster care, adopted adolescents, or young care leavers aged 14 to 21 years.

Results
Ethical approval was granted by the Ethics Committee of the Medical School Berlin in March 2021 (MSB-2021/55). Recruitment started in September 2021 and is planned until November 2022. The results are expected to be published in January 2023.

Conclusions
Given the increased likelihood for future victimization experiences among youth in care, there is a strong need for a low-threshold intervention specifically for this high-risk age group. There are no existing nationwide mental health programs exclusively for youth in care in Germany.

The Outcomes of App-Based Health Coaching to Improve Dietary Behavior Among Nurses in a Tertiary Hospital: Pilot Intervention Study
Authors: Lim Wei Xiang , Fook-Chong Stephanie , Lim John Wah , Gan Wee Hoe 
Published: June 2022

Background
At the workplace, health care workers face multiple challenges in maintaining healthy dietary behaviors, which is the major factor behind obesity. A hospital-wide mass health screening exercise showed an increasing trend in the prevalence of obesity and median BMI from 2004 to 2019, as well as a higher crude obesity rate among shift workers.

Objective
We aimed to evaluate the effectiveness of mobile app–based health coaching and incentives for achieving weight loss from better dietary choices among hospital nurses.

Methods
We conducted a pilot study from June 2019 to March 2020, involving the use of a health-coaching app by 145 hospital nurses over 6 months. Weight and BMI were self-reported, and food scores were calculated. Data among overweight nurses, shift work nurses, and incentive groups were analyzed.

Results
A total of 61 nurses were included in the final analysis. Of these 61 nurses, 38 (62%) lost weight. The median percentage weight loss was 1.2% (IQR 0%-2.9%; P<.001), and the median decrease in BMI was 0.35 (IQR −0.15 to 0.82; P<.001), but they were not clinically significant. The median improvement in the food score was 0.4 (IQR 0-0.8). There was no difference between the incentive and nonincentive groups. A total of 49 (34%) participants engaged for ≥8 weeks.

Conclusions
The study demonstrated an association between the use of app-based health coaching and the attainment of some weight loss in nurses, without a significant improvement in the food score. Incentives may nudge on-boarding, but do not sustain engagement.

Rationale. Portal blood flow is a key component in the viability of the liver transplant.Portocaval shunts formed on the background of the liver cirrhosis before transplantation can cause portal vein steal syndrome, with subsequent development of ischemic necrosis of the graft.To date, the tactics of treating patients with portal vein steal syndrome during liver transplantation has not been sufficiently developed.This paper presents a literature review and our own experience on this important, but little-studied issue.Purpose. The purpose of this research is to study the role of portocaval shunts in the development of complications after liver transplantation, based on a retrospective analysis of clinical cases.Conclusions. In liver transplantation, portocaval shunts can cause the development of portal vein steal syndrome with subsequent development of liver failure. For the diagnosis of portal vein steal syndrome, it is important to use the data obtained at all stages of liver transplantation. Surgical correction of portal vein steal syndrome can be performed during liver transplantation and in the early postoperative period.
The Interpellation of Misogyny By Female Characters
Authors: Septia Larassati Alya , Wahyuni Delvi 
Published: June 2022

This thesis is an analysis of Otessa Moshfegh's novel entitled EILEEN (2015). This analysis is related to the concept of Interpellation by Luis Althusser and Misogyny by SheilaJeffrey and it is under the Feminist literary theory which can reveal issues in the novel. This can be seen in two methods: form of misogynistic women and the way misogyny can get interpellated. The issues raised are women who interpellated the ideology of misogyny and they also did it. Self-judgement, self-objectification, and negative attitude toward other women are the dominant forms of mysoginistic behaviour expressed by female characters in this novel. Family and workplace are the place or the background how this ideology can be interpellated. The analysis shows that misogyny is not only done by men but women also do it. It can be concluded that the ideology formed by these patriarchs is indirectly also supported by women.

Green infrastructure and planning procedures – experience of creating an unofficial network of green spaces as an NGO
Authors: Spajić Marijo 
Published: June 2022

Abstract
Article focuses on recognizing valuable green spaces and strategic positioning of new green infrastructure elements in space from the perspecitve of a non-governmental organization. It questions the limitations, roles, and possibilities of non-governmental organizations (NGO‘s) in the establishment of publicly accessible and environmentally significant areas in the urban matrix. The article considers personal experiences in the implementation of such projects, their influence on the daily livelihood of citizens and how an NGO can contribute bypassing current absence of legal basis for its implementation. The methods presented in the paper are described as informative guidelines and are not scientifically backed, although they do rely on scientific knowledge of the members of NGO and previously tried methods of earlier finds. This work represents a factual outcome of actions delivered by the NGO ZIPS (Zelene i plave Sesvete) and do not have to be replicative on other showcase examples, considering their legal, cultural, and other backgrounds.
Population analysis of smallmouth silverside, Chirostoma chapalae Jordan & Snyder, 1899 (Atherinopsidae), an endemic fish in Lake Chapala, Mexico
Authors: Gomez-Vanega Hosmer Duvan , Espino-Barr Elaine , López-Uriarte Ernesto 
Published: June 2022

Abstract
A sample was analyzed of 1,129 specimens of Chirostoma chapalae from Lake Chapala, Mexico obtained from catches of local fishers between October 2016 and September 2017. Size frequency, length-weight relationships (LWRs), growth, mortality, exploitation rate, survival rate, and relative condition index were estimated. The LWRs showed negative allometric growth in females (b = 2.735) and isometric growth in males (b = 3.000). The SL∞ was 9.20 cm in females and 8.94 cm in males, and the growth coefficient k ranged from 1.80 year−1 to 1.90 year−1, and the t0 from 0.119 to 0.113. Estimated total mortality (Z = 3.20 year−1), natural mortality (M = 1.56 year−1), and fishing mortality (F = 1.64 year−1) values were higher in females. C. chapalae is at optimum, underexploited levels according to the exploitation rate (E = 0.42 year−1). The SL at first capture (SLpc) was 65.8 mm and the SL at retention (SLpr) of the fishing gear was 62.4 mm. This indicates that more than 50% of the fish caught enter the fishery at a larger size. The condition factor (Kn) showed body robustness in fall and subsequent spawning from spring onwards. Our findings contribute to the future development of fisheries management strategies in the largest lake in Mexico.
Stock discrimination of Etroplus suratensis (Bloch) along the South Indian coast by morphometric analysis
Authors: Chandrasekar Shanmugam , Mathialagan Ramasamy , Thangaraj Muthusamy 
Published: June 2022

Abstract
The objective of the present study was to analyze the morphometric and meristic variations of an estuarine fish, Etroplus suratensis, in five locations along the South Indian coastal region. In total, 651 individuals were collected and 16 morphometric and six meristic counts were taken. The results of univariate (ANOVA) and multivariate (Principal Component Analysis, PCA) analyses showed that the east coast stocks (Machilipatnam, Mudasalodai, Rajakkamangalam) have overlapping morphological characteristics, whereas the west coast stock (Cochin) was distinctly different, but there were no significant differences observed in meristic characters among the five stocks. Therefore, it was presumed that Machilipatnam, Mudasalodai, and Rajakkamangalam were the same stock. The morphometric data discriminated E. suratensis into two stocks, i.e., those of the east and west coasts. However, further molecular-based analysis is very much needed to validate these stocks.
