Toxicological Effects of Nanomaterials on the Aquatic Biota
Authors: Usman U.L.
Published: October 2022

Globally nanotechnology has transformed many sectors of human endeavour due to the innovative introduction of different unique materials and products in various areas. Presently large quantities of nanomaterials are synthesized and are essential for several industrial applications. This facilitates and enhances research in biophysics, biochemistry, wastewater treatment, etc. Nanotechnology and other science-related discipline have been combined to synthesize novel nanomaterials through modification of their shapes, composition, and dimension which can be used for various applications in medicines, agriculture, environmental remediation, etc. Despite their peculiar advantages and wide application in several industrials and domestic sectors, fabricated materials of nano-size scale have been raising concerns of unsafety for both human and aquatic biota, due to their incessant release into the aquatic ecosystem. These nanomaterials are ingested by the aquatic biota, from which they bioaccumulate in the organism’s body and hence pass to humans via the food chain. Within the organism’s body, nanomaterials serve as foreign material with different physicochemical characteristics because of their peculiar small sizes. Thus, the harmful effect of nanomaterials on aquatic biota has been generating great concern among the scientific communities. Thus, they can interfere with the normal mechanisms of physiological activities. The present chapter focuses on the sources of the nanomaterials in the aquatic ecosystem, the route of exposure, their process of transformation and interactions, their possible toxicity to the aquatic biota, challenges posed by the nanomaterials, and prospects.

The problem of parametric identification of some nonlinear models of fast
hydrogen permeability of alloys for membrane technologies for the release of high-purity
hydrogen (on the example of alloy B1) is solved. Not only diffusion in the bulk of the material is
taken into account, but also physical and chemical processes on the surface: adsorption,
desorption and rapid dissolution. The mathematical software and the results of numerical
simulation for a three-stage breakthrough experiment with vacuum pumping at the membrane
outlet from the structural material under study are presented. The influence of the accumulation
of atomic hydrogen on the surface has been studied.

Authors: Готт Ю.В. , Юрченко Э.И.
Published: October 2022

The operation of a thermonuclear reactor on an alternative to D-T fuel (D-D, Cat-DD, D−3He, p−11B, p−6Li) requires a higher temperature of the fuel mixture and an increased plasma energy confinement time. It is shown that at a fixed power of thermonuclear reaction, an increase in the peaking of plasma parameters leads to a decrease in power, which is necessary to its addition heating. Moreover, the peaking of the plasma parameters leads to decrease of its radiation losses. All this reduces the requirements for the operating conditions of thermonuclear reactor.

Published: October 2022

An vectorial mode solver for microstructured optical fibers based on the representation of the longitudinal components of the mode fields at the interfaces of media in the fiber cross section by Fourier series in angular variables is formulated. The coefficients of the series are found from a homogeneous algebraic system solved by the reduction method. The matrix elements of the system are determined on the basis of the Green's theorem, which is considered in the internal and external regions of the fiber cross section and the inclusions that form the microstructure. The elements are represented by regular integrals, i.e. difficulties associated with the singularities of the Green's functions are absent. The applicability of the approach is limited only by the requirement that the contours of the inclusions and the outer boundary of the fiber are described by single-valued functions of the angular variables. In the special case of a circular dielectric waveguide, the method gives an exact analytical solution of the waveguide problem. Estimates are obtained for the internal convergence of the method in computing the modes of a dielectric elliptical waveguide and microstructural fibers with elliptical inclusions. It is established that the attenuation coefficients of the modes caused by radiation leakage from the fiber core are significantly affected by both the internal microstructure and the outer fiber boundary.
Методические аспекты изучения параметров упругих волн и контроль эталонной формы акустической эмиссии в полевых условиях
Authors: Махмудов Х.Ф.
Published: October 2022

Для измерения энергии источника акустических импульсов в абсолютной шкале единиц (J) по регистрируемым импульсам был проведен анализ энергетического баланса "источник имульсов"--"передающая среда"--"приемник импульсов" с применением аппарата спектрального анализа. Сопоставление двух независимых методов определения энергии упругого взаимодействия (емкостной метод и метод фотоупругости) дало расхождение результатов менее чем на 12%. Определен спектральный состав энергии взаимодействия. Результаты позволяют определить как параметры источника сигнала, так и структуру передающей с трансформацией сигнала среды. Для измерения напряжений в упругой волне был изготовлен и калиброван пьезоприемник, в котором чувствительным элементом служила пьезопленка. Этот приемник в отличие от приемников, выполненных на базе пьезокерамических элементов, обладает существенно меньшей нелинейностью амплитудно-частотной характеристики, поскольку имеет только две собственные частоты. Ключевые слова: фотоупругость, скорость упругих волн, горный массив, бетон, акустическая эмиссия.
Validity of Chatbot Use for Mental Health Assessment: Experimental Study
Authors: Schick Anita , Feine Jasper , Morana Stefan , Maedche Alexander , Reininghaus Ulrich
Published: October 2022

Background

Mental disorders in adolescence and young adulthood are major public health concerns. Digital tools such as text-based conversational agents (ie, chatbots) are a promising technology for facilitating mental health assessment. However, the human-like interaction style of chatbots may induce potential biases, such as socially desirable responding (SDR), and may require further effort to complete assessments.

Objective

This study aimed to investigate the convergent and discriminant validity of chatbots for mental health assessments, the effect of assessment mode on SDR, and the effort required by participants for assessments using chatbots compared with established modes.

Methods

In a counterbalanced within-subject design, we assessed 2 different constructs—psychological distress (Kessler Psychological Distress Scale and Brief Symptom Inventory-18) and problematic alcohol use (Alcohol Use Disorders Identification Test-3)—in 3 modes (chatbot, paper-and-pencil, and web-based), and examined convergent and discriminant validity. In addition, we investigated the effect of mode on SDR, controlling for perceived sensitivity of items and individuals’ tendency to respond in a socially desirable way, and we also assessed the perceived social presence of modes. Including a between-subject condition, we further investigated whether SDR is increased in chatbot assessments when applied in a self-report setting versus when human interaction may be expected. Finally, the effort (ie, complexity, difficulty, burden, and time) required to complete the assessments was investigated.

Results

A total of 146 young adults (mean age 24, SD 6.42 years; n=67, 45.9% female) were recruited from a research panel for laboratory experiments. The results revealed high positive correlations (all P<.001) of measures of the same construct across different modes, indicating the convergent validity of chatbot assessments. Furthermore, there were no correlations between the distinct constructs, indicating discriminant validity. Moreover, there were no differences in SDR between modes and whether human interaction was expected, although the perceived social presence of the chatbot mode was higher than that of the established modes (P<.001). Finally, greater effort (all P<.05) and more time were needed to complete chatbot assessments than for completing the established modes (P<.001).

Conclusions

Our findings suggest that chatbots may yield valid results. Furthermore, an understanding of chatbot design trade-offs in terms of potential strengths (ie, increased social presence) and limitations (ie, increased effort) when assessing mental health were established.
Tooth-Related Disease Detection System Based on Panoramic Images and Optimization Through Automation: Development Study
Authors: Kim Changgyun , Jeong Hogul , Park Wonse , Kim Donghyun
Published: October 2022

Background

Early detection of tooth-related diseases in patients plays a key role in maintaining their dental health and preventing future complications. Since dentists are not overly attentive to tooth-related diseases that may be difficult to judge visually, many patients miss timely treatment. The 5 representative tooth-related diseases, that is, coronal caries or defect, proximal caries, cervical caries or abrasion, periapical radiolucency, and residual root can be detected on panoramic images. In this study, a web service was constructed for the detection of these diseases on panoramic images in real time, which helped shorten the treatment planning time and reduce the probability of misdiagnosis.

Objective

This study designed a model to assess tooth-related diseases in panoramic images by using artificial intelligence in real time. This model can perform an auxiliary role in the diagnosis of tooth-related diseases by dentists and reduce the treatment planning time spent through telemedicine.

Methods

For learning the 5 tooth-related diseases, 10,000 panoramic images were modeled: 4206 coronal caries or defects, 4478 proximal caries, 6920 cervical caries or abrasion, 8290 periapical radiolucencies, and 1446 residual roots. To learn the model, the fast region-based convolutional network (Fast R-CNN), residual neural network (ResNet), and inception models were used. Learning about the 5 tooth-related diseases completely did not provide accurate information on the diseases because of indistinct features present in the panoramic pictures. Therefore, 1 detection model was applied to each tooth-related disease, and the models for each of the diseases were integrated to increase accuracy.

Results

The Fast R-CNN model showed the highest accuracy, with an accuracy of over 90%, in diagnosing the 5 tooth-related diseases. Thus, Fast R-CNN was selected as the final judgment model as it facilitated the real-time diagnosis of dental diseases that are difficult to judge visually from radiographs and images, thereby assisting the dentists in their treatment plans.

Conclusions

The Fast R-CNN model showed the highest accuracy in the real-time diagnosis of dental diseases and can therefore play an auxiliary role in shortening the treatment planning time after the dentists diagnose the tooth-related disease. In addition, by updating the captured panoramic images of patients on the web service developed in this study, we are looking forward to increasing the accuracy of diagnosing these 5 tooth-related diseases. The dental diagnosis system in this study takes 2 minutes for diagnosing 5 diseases in 1 panoramic image. Therefore, this system plays an effective role in setting a dental treatment schedule.

Authors: Nikookar Seyed Hassan , Maleki Alireza , Fazeli-Dinan Mahmoud , Shabani Kordshouli Razieh , Enayati Ahmadali
Published: October 2022

Background

Arboviral diseases such as dengue, Zika, and chikungunya are transmitted by Aedes aegypti and Ae albopictus and are emerging global public health concerns.

Objective

This study aimed to provide up-to-date data on the occurrence of the invasive Aedes species in a given area as this is essential for planning and implementing timely control strategies.

Methods

Entomological surveillance was planned and carried out monthly from May 2018 to December 2019 at higher-priority entry points in Guilan Province, Northern Iran, using ovitraps, larval collection, and human-baited traps. Species richness (R), Simpson (D), evenness (E), and Shannon-Wiener indexes (H̕) were measured to better understand the diversity of the Aedes species. The Spearman correlation coefficient and regression models were used for data analysis.

Results

We collected a total of 3964 mosquito samples including 17.20% (682/3964) belonging to the Aedes species, from 3 genera and 13 species, and morphologically identified them from May 2018 to December 2019. Ae vexans and Ae geniculatus, which showed a peak in activity levels and population in October (226/564, 40.07% and 26/103, 25.2%), were the eudominant species (D=75.7%; D=21.2%) with constant (C=100) and frequent (C=66.7%) distributions, respectively. The population of Ae vexans had a significant positive correlation with precipitation (r=0.521; P=.009) and relative humidity (r=0.510; P=.01), whereas it was inversely associated with temperature (r=−0.432; P=.04). The Shannon-Wiener Index was up to 0.84 and 1.04 in the city of Rasht and in July, respectively. The rarefaction curve showed sufficiency in sampling efforts by reaching the asymptotic line at all spatial and temporal scales, except in Rasht and in October.

Conclusions

Although no specimens of the Ae aegypti and Ae albopictus species were collected, this surveillance provides a better understanding of the native Aedes species in the northern regions of Iran. These data will assist the health system in future arbovirus research, and in the implementation of effective vector control and prevention strategies, should Ae aegypti and Ae albopictus be found in the province.

Authors: Richter Aliah , Adkins Victoria , Selkie Ellen
Published: October 2022

Background

Despite increasing prevalence of phone ownership in early adolescence, there is a deficit of evidence-based guidance on the appropriate time to provide youth their first phone.

Objective

This survey study explored age recommendations for phone ownership among a diverse panel of youths, as their experiences are an important contribution to the development of ownership guidelines.

Methods

Participants were recruited from MyVoice, a national panel of over 765 youth (14 to 24 years old) who respond to weekly SMS text message–based surveys. Questions were distributed between January 24 2018, and March 20, 2018. Inductive qualitative analysis was used to identify major themes among youths’ open-ended responses.

Results

In all, 469 youth (mean age 18.8 years; female: 299/469, 63.8%; White race: 332/468, 70.8%) responded. On average, respondents obtained their first phone at 12.2 years of age. Most participants (325/459, 71.1%) stated they received their first phone out of necessity rather than for entertainment or social reasons. Youth recommended that early adolescents receive their first phone between 12 and 13 years of age primarily for reasons of necessity (146/448, 32.6%).

Conclusions

According to the participants, phones supported safety and independence by allowing communication with parents and participation in activities. Youth-serving professionals and parents can incorporate these youth perspectives into shared decision-making about phone ownership among families. This can include discussions about essential features, safety, or phone use, as well as maturity and responsibility milestones, which were all key considerations reported by participants in the survey.

Authors: Srinivasan P , Hariharan S , Manikandan P , Naveenkumar S , Harish N , Balasubramanian G
Published: October 2022

Abstract: This study aims to examine the shrinkage flaw in grey cast iron. The poor gating system design, improper composition management, and solid sections with a high modulus (Volume/ Surface area) in the casting are the root causes of the shrinkage fault. The gating mechanism can first be redesigned in order to lessen shrinkage. A new gating system with a different chemical makeup is suggested. Grey cast iron's composition changed due to an increase in carbon content. Thus, proCAST is used to develop and analyze the gating system. Implementing the planned gating system in the foundry served to validate the results. It is accomplished to increase the effective yield

Published: October 2022

Purpose: We aimed to survey current status of preparedness for neonatal resuscitation in delivery rooms in Korea.Methods: We analyzed data regarding preparedness for the resuscitation in terms of personnel, equipment, and education using a questionnaire, which was developed by the Korean Association of Cardiopulmonary Resuscitation. From August 2020 through January 2021, the questionnaires were sent to hospitals affiliated with the Korean Association of Maternity Hospitals or the Korean Neonatal Network (KNN) operated by the Korean Society of Neonatology. As per the affiliated society, the hospitals were grouped as the maternity hospitals or the KNN hospitals. The questionnaires were delivered in 3 steps: mailout, electronic mail, and phone calls. Results: Response rate was 21.3% (115 of 541) and 65.3% (49 of 75) in the maternity and KNN hospitals, respectively. The maternity hospitals showed a higher mean number of delivery and fewer pediatricians. In the KNN hospitals, pediatricians played a leading role during the resuscitation, but in the maternity hospitals, their role as a leader was less conspicuous. The KNN hospitals were better equipped with masks of variable sizes, oxygen blender, T-piece resuscitator, and electrocardiographic monitor (all Ps < 0.001). In the maternity hospitals, the preparedness of oxygen blender or T-piece resuscitator was positively associated with the number of pediatricians (P = 0.005). Although bag-mask ventilation was mostly feasible in both groups, endotracheal intubation was less feasible in the maternity hospitals (P = 0.007). The annual participation in resuscitation training for providers was higher in the KNN hospitals (P < 0.001). In the maternity hospitals, the annual participation was positively associated with the numbers of deliveries, obstetricians, and pediatricians.Conclusion: This preliminary survey indicates the need for further improvement in preparing in personnel, equipment, and education, particularly in maternity hospitals.
Biomolecular Histology as a Novel Proxy for Ancient DNA and Protein Sequence Preservation
Authors: Anderson Landon A.
Published: October 2022

Researcher ability to accurately screen fossil and sub-fossil specimens
for preservation of DNA and protein sequences remains limited. Thermal
exposure and geologic age are usable proxies for sequence preservation
on a broad scale but are of limited use for specimens of similar
depositional environments and/or ages. Cell and tissue biomolecular
histology is thus proposed as a proxy for determining sequence
preservation potential of ancient specimens with improved accuracy.
Biomolecular histology as a proxy is hypothesized to elucidate why
fossil/sub-fossils of some depositional environments and or geologic
ages preserve sequences while others do not and to facilitate selection
of ancient specimens for use in molecular studies.

Published: October 2022

We built a molecular-level kinetic model for hydrocarbon catalytic
cracking, incorporating the catalyst acidity as the parameter to
estimate the reaction rates. The n-decane and 1-hexene co-conversion
catalytic cracking process was chosen as the studying case. The reaction
network was automatically generated with a computer-aided algorithm. A
modified linear free energy relationship was proposed to estimate the
activation energy in a complex reaction system. The kinetic parameters
were initially regressed from the experimental data under various
reaction conditions. On this basis, the product composition was
evaluated for three catalytic cracking catalysts with different Si/Al.
The Bronsted acid and Lewis acid as the key catalyst properties were
correlated with the kinetic parameters. The built model can calculate
the product distribution, and molecular composition at different
reaction conditions for different catalysts. The sensitive study shows
that it will facilitate the model-based optimization of catalysts and
reaction conditions according to product demands.

Published: October 2022

BACKGROUND Preoperative evaluation of Image Defined Risk Factors (IDRFs)
in neuroblastoma (NB) is crucial for determining suitability for upfront
resection or tumor biopsy. IDRFs are linked with a higher potential
morbidity at operation and lessen the chance of complete tumor
resection. The IDRFs do not all carry the same weight in predicting
tumor complexity and surgical risk. In this study we aimed to assess and
categorize the degrees of surgical complexity (Surgical Complexity
Index, SCI) in NB resection.  PROCEDURE A panel of 15 surgeons was
involved in an electronic Delphi consensus survey to identify and score
a set of shared items predictive and/or indicative of surgical
complexity, including the number of preoperative IDRFs. Risk categories
included - (a) Standard risk; (b) Moderate risk; (c) High risk; (d) Very
high risk. A shared agreement included the achievement of at least 75%
consensus focused on a single category or, alternatively, on the sum
between the prevailing category and an immediately closest one. RESULTS
After 3 Delphi rounds, agreement was established on 25/27 items
(92.6%). A severity score was established for each item ranging from 0
to 3 with an overall SCI range varying from a minimum score of zero to a
maximum score of 29 points for any given patient.  CONCLUSIONS A
consensus on a SCI to stratify the risks related to tumor resection was
established by the panel experts. This index will now be deployed to
critically assign a better severity score to IDRFs involved in NB
surgery.
Myeloid-derived suppressor-like cells - does their frequency change in patients with different stages of CRC?
Authors: Brcerevic Irina , Doder Radoje , Perisic Nenad , Petrovic Stanko , Vojvodic Danilo
Published: October 2022

Background/Aim. Colorectal cancer (CRC) is one of the most common cancers in the population, often leading to lethal outcomes. Myeloid-derived suppressor cells (MDSCs) belong to a heterogeneous group of immature cells thought to have an immunosuppressive effect that may aid in tumor development and spreading. The aim of this study was to analyze the frequency and significance of MDSC-like cells at different stages in patients with CRC. Methods. Peripheral blood (PB) samples of 83 patients at different stages of the disease and 12 healthy subjects (control group) were analyzed. MDSC-like cells were identified and enumerated in the PB samples of the participants based on the immuno-phenotypic characteristics of the cells. Results. A statistically significant increase in the absolute and relative number of polymorphonuclear (PMN) MDSC (PMN-MDSC)-like cells was observed in the PB of all the patients with CRC, com-pared to the healthy control group (p < 0.0001). No significant increase was observed in monocytic MDSC (M-MDSC)-like cells when they were analyzed without CRC stage stratification (p > 0.05). When the relative and absolute numbers of PMN-MDSC-like cells were analyzed in relation to the stages of CRC disease (TNM classification), a statistically significant difference was observed between the control group and patients in stages III and IV of the dis-ease (p = 0.0005 vs. p = 0.0003 and p < 0.0001 vs. p < 0.0001, respectively). There was, as well, a significant difference when the numbers of PMN-MDSC-like cells in patients in stages I and II were compared to numbers in patients in stage IV of the CRC (p = 0.0161 vs. p < 0.0001 and p = 0.0065 vs. p < 0.0001, respectively). A statistically significant difference in the relative and absolute number of M-MDSC-like cells was observed only between patients in stages II and IV of the disease (p = 0.0014 and p = 0.0002, respectively). The highest number of MDSC-like cells was observed in stage IV of the disease according to the TNM classification. A positive correlation between the presence of these cells and the number of organs affected by metastatic changes was observed (p < 0.0001 for the relative and absolute number of PMN-MDSC-like cells and p = 0.003 and p = 0.0004 for the relative and absolute number of M-MDSC-like cells). Conclusion. CRC patients had a statistically significant increase in PMN-MDSC-like cells compared to healthy controls. The increase in absolute and relative numbers of these cells mostly follows the growth and progression of CRC, while a statistically significant difference in the number of M-MDSC-like cells is observed only between stages II and IV of the disease. The absolute and relative numbers of both subtypes of MDSC-like cells significantly correlate with the number of organs affected by CRC metastases.

Matija Nenadovic as an active witness of Serbian real re-historization
Authors: Koprivica Caslav
Published: October 2022

In the following article, the authors will explore Matija Nenadovic in order
to highlight the importance of one of the leaders of the First Serbian
Uprising in the process of Serbian returning to the historical scene, after
falling into centuries-long slavery under the Ottomans. Nenadovic is
important in many ways for understanding the problem of Serbian real
rehistorization - as regaining the capacity for historical action of Serbs -
both as an actor and a witness, but also as someone who appears to seek to
reflexively appropriate and authoritatively shape the emerging Serbian
history. It turns out that the transition from Ottoman, non-European
premodernity to own-statehood-substantitated modernization in freedom can be
taken as the red thread of integrally observed unity of Nenadovic?s actions
and reflections.
The influence of motivation and job satisfaction on employee performance
Authors: Cvjetkovic Milena
Published: October 2022

Employee motivation and job satisfaction are the subject of numerous studies.
This topic is an inexhaustible source of new knowledge and due to its
relevance, it occupies the attention of many researchers. Modern business
flows dictate the conditions from which new factors arise that encourage
employee motivation and satisfaction. A satisfied worker is driven by
enthusiasm that motivates him to achieve more effective work results. Such
workers affect higher productivity, which contributes to more efficient
achievement of organizational goals. The subject of this paper is the
analysis of the impact of motivation and job satisfaction on business
performance of employees. The results of the correlation analysis confirmed
the existence of statistically significant relationships between the
variables of motivation and job satisfaction and the variables of
employee performance. The regression model indicated that employee motivation
factors had the greatest impact on taking the initiative as
employee performance. The variables of employee motivation that have made the
largest individual contribution to employee performance are satisfactory
remuneration and fair organizational policies and rules. The results of the
regression analysis confirmed the greatest influence of job satisfaction

Bank performance analysis and identification of key determinants of electronic banking customer satisfaction - balanced scorecard approach
Authors: Jolovic Nevena , Jolovic Ivana , Zdravkovic Stefan
Published: October 2022

The issue of adequate measurement of the use of intangible assets and
monitoring its impact on the financial performance of the organization in
recent decades is bridged by a measurement-managerial model that unites
financial and non-financial performance indicators - Balanced Scorecard
(BSC). Since this paper focuses on banks as representatives of specific,
modern financial organizations, the subject of research is to examine the
possibility of applying this model in the analysis of banking performance.
The aim of the research is to analyze, by using the qualitative methodology
(review of existing papers in the literature), whether the BSC model is
applicable for the analysis of banking performances; and then, by using the
quantitative methodology, through connecting two perspectives of the same
model (perspective of internal business processes and perspective of
customers), to examine how the determinants of TAM model (perceived
usefulness, ease of use) and determinants of SERVQUAL model (perceived
security and privacy, responsibility) affect electronic banking customer
satisfaction. The empirical research was conducted through the survey method
on the territory of the Republic of Serbia at the end of 2020, and the
sample included 324 respondents. Statistical software SPSS Statistics was
used to process the collected data. Based on the literature review, it was
found that the BSC model is applicable for the analysis of banking
performances. The results of the empirical research have shown that
perceived usefulness, perceived security and privacy, and responsibility
have a positive statistically significant impact on the satisfaction of
electronic banking users, while ease of use does not have a statistically
significant impact on the satisfaction of mentioned users.
Destructive reflections of the legislative framework of the Republic of Serbia on the wages of private sector employees as a reward to their devotion to the economy in crisis caused by the SARS-CoV-2 virus pandemic
Authors: Jovanovic Tatjana
Published: October 2022

Among the many problems which follow the economies of countries around the
world, and primarily countries in transition, the end of the first quarter
of 2020 brought an unexpected scenario - pandemic caused by SARS-CoV-2
virus. The pandemic did not bypass the Republic of Serbia, nor her economy.
Living in uncertainty and fearing for own life and families life, but also
the people around them, not a small number of employees in the private
sector were devoted to employers who did not suspend business during the
state of emergency in the Republic of Serbia. However, the legislative
framework of the Republic of Serbia does not seem to adequately recognize
their devotion and sacrifice, as one of the key links in maintaining
economic activity in extraordinary circumstances. Most of the provisions of
both laws and bylaws passed before, but also during the declared state of
emergency, have a very destructive effect on wages, and the right of private
sector employees to use, dispose of and enjoy their entire, dignified wages.
The right of employees to increase wages based on time spent at work for
each full year of employment with the employer, past years of work, the
right to payment of real food costs during work and the costs of arrival and
departure from work, are just some of the more specific areas, provisions of
which have long been on the side the ?will? of employers. That the previous
practice was mostly maintained even during the state of emergency is
evidenced by certain acts adopted in the midst of the crisis. Thus, the
enabled fiscal benefits ?abduct? part of the wages of employees and give it
to employers, and direct cash benefits create inequality between employees
employed during the state of emergency and those that were not.

Objective: To provide a systematic review of the literature and knowledge base of cost per quality-adjusted life year of physical rehabilitation and care of older persons after hip fracture.Material and methods: A research librarian assisted in searching 9 databases (14 May to 27 May 2021), with exclusion of studies on cognitively impaired or institutionalized individuals. A stepwise selection process was conducted by 2 authors, study quality was assessed using Drummond et al.’s checklist, and comparison between different countries was assessed using Welte et al.’s checklist.Results: Three studies were included, which employed 3 different interventions initiated at 3 different postoperative time-points. One high-quality study demonstrated that comprehensive geriatric assessment was cost-effective compared with coordinated care. The other 2 studies did not find the interventions studied to be cost-effective, and both studies were deemed to be of moderate quality.Conclusion: The body of evidence on the cost-effectiveness of physical rehabilitation and care after hip fracture is limited and heterogeneous, with only 1 high-quality study. Thus, stakeholders perform decision-making with a limited knowledge base of the cost-effectiveness of physical rehabilitation and care. We recommend researchers to assess cost-per-QALY.
LAY ABSTRACTHip fractures have severe consequences for older persons and, after surgery, patients need physical rehabilitation and care to recover. Physical rehabilitation and care vary greatly in terms of effectiveness and cost. It is not known what kind of physical rehabilitation and care contribute most to health relative to their costs. This systematic review provides the first comprehensive description of the cost- effectiveness of physical rehabilitation and care of older persons after hip fracture. Nine databases were searched, and 3 economic evaluation studies were identified. One economic study identified comprehensive geriatric care as cost-effective compared with usual coordinated care. The other two studies consisting of an intervention of additional 10 weeks of physical rehabilitation initiated 4 months after discharge and an intervention physical rehabilitation and nutrient management proved not cost-effective compared to usual rehabilitation and care. In conclusion, the number of studies published in this field is very limited and further research is necessary.
Deposition strategies for generating cuboid volumes using extreme high-speed directed energy deposition

Published: October 2022

Extreme high-speed directed energy deposition (EHLA) is a variant of directed energy deposition (DED-LB) developed at Fraunhofer ILT in cooperation with RWTH Aachen University. Because of a powder gas jet setup that is aimed at melting particles in the laser beam before they enter the melting pool, high process speeds of up to several hundred meters per minute and a layer thickness as thin as 25 μm can be achieved. EHLA is generally applied for rotationally symmetric coating applications. In previous experiments on a prototype machine of ponticon GmbH, EHLA was used for building up dense volumes, thus qualifying its use for additive manufacturing, now termed EHLA 3D. In this work, using iron-base alloy 1.4404 and a process speed of 40 m/min, cubic volumes are produced with EHLA 3D. Different deposition strategies commonly used in DED-LB are tested for their transferability to EHLA 3D. The results of different deposition strategies achieving the best near net shape geometry are shown in comparison to DED-LB. Furthermore, the influence of the deposition strategy and used technology on thermal management and microstructure are investigated. The best near net shape is achieved in this comparison using a contour-hatch strategy with 1.5 contours per layer and a 90° rotation of the hatch, both for EHLA and DED-LB. The microstructure of EHLA 3D built cubes is more similar to a typical laser powder bed fusion microstructure than to a typical DED-LB microstructure with respect to grain size and structure.

Fish drying by using additional salt as a preservative and adding flavor to the fish. This study aims to determine the effect of various doses of salt on the quality of tilapia, motan, dried salted lemongrass and the difference that does not use salt on the quality of fish. This type of research is quantitative research with experimental methods. The independent variable in this study was the concentration of NaCl salt as a treatment, namely 10%, 20%, 30% of the total fish weight. The controlled variables of this study were the type of fish, weather conditions, and materials used. The research process begins with weeding motan, tilapia, and lemongrass fish, namely motan fish, tilapia, and lemongrass fish, weighing 100 grams. Then the fish are weeded with running water, removed all the contents of the fish's stomach, and drained until the fish does not contain too much water. Then the addition of salt to the motan fish, tilapia, and lemongrass fish has been given, namely, 27%, 34%, and 41%. The duration of soaking or salting is 24 hours. After the salting time has been completed, the fish drying process is continued. The fish dried at a temperature of 30C to 35C for 2 to 3 days to obtain the desired characteristics of salted fish. Data was collected by testing the salt content in fish with different concentrations. The results showed a difference between salted fish and unsalted fish. Salted fish has a harder texture, taste better, and have a longer shelf life.

Salted fish is one of the side dishes that are in great demand by the people of Indonesia. This study aims to analyze the effectiveness of the use of direct sunlight on the drying process of salted fish without formalin. The method used in this research is the experimental method. Where this data collection uses various types of fish to be used as salted fish and there are also some fish that are not salted. The types of fish used in this study were river fish, tilapia, singkek fish, and marine fish. The process of making this salted fish lasts 3-5 days. It depends on the type of fish used and the weather or sunlight during the drying process. The drying process of salted fish that is applied is using direct sunlight or traditionally and does not use chemicals or formalin. The results obtained during drying, fish that do not use salt easily spoil quickly and cannot last long. The smell of unsalted fish is more pungent and the color of the fish also changes. While the fish that is given salt does not smell bad, the color of the fish also does not change.
