Sperm cryopreservation is an effective fertility preservation method for cancer patients before anticancer treatments. However, there are little data on fertility preservation in large cohorts of patients with cancer in southern China. This retrospective cross-sectional study aimed to assess the fertility preservation status of 1034 newly diagnosed male patients with cancer in the Human Sperm Bank of Guangdong Province in southern China (Guangzhou, China). Of these, 302 patients had reproductive system tumors, mostly testicular cancers (99.0%), and 732 had other tumors, including lymphoma (33.1%), gastrointestinal cancer (16.3%), nasopharyngeal carcinoma (15.7%), leukemia (7.7%), sarcoma (3.6%), and others (23.6%). Patients with reproductive system tumors had lower sperm concentration and prefreezing and post-thawing progressive motility than those with non-reproductive system tumors (all P < 0.001). Differences in sperm concentration, progressive motility, and normal morphology rate were observed between patients with and without anticancer surgery before sperm cryopreservation (all P < 0.05). As of April 30, 2022, 63 patients used their cryopreserved sperm for assisted reproductive technology treatments and 39 pregnancies were achieved. This study provides valuable data on the fertility preservation status in newly diagnosed cancer patients in southern China, demonstrating that patients with reproductive system tumors had poor sperm quality for their pretreatment fertility preservation.

Published: December 2022

Filariasis is a common, yet neglected tropical disease and has a wide spectrum of clinical presentations. It is particularly endemic in certain regions of India. We report this case due to the rare isolation of Microfilariae from the bone marrow aspirate preparation. Here, we report a patient with a history of pyrexia of unknown origin (PUO). The relevant investigations done failed to identify the causative organism. After ruling out routine causes of fever, bone marrow analysis was done and it revealed Microfilariae in the aspirate. The surprising aspect of the case is the absence of eosinophilia in the complete blood picture. The patient was treated with anthelmintics and the fever subsided within 48 h. This case emphasizes the importance of bone marrow study in patients with PUO and the presence of microfilaria in the absence of eosinophilia.
Could Mouth Breathing Lead to Adenoid Hypertrophy?
Authors: Ma Xiao-Kai , Wang Qingyu
Published: December 2022

Introduction:

Adenoid hypertrophy (AH), an immune response of the body against infections, is common in children and has adverse effects on their physical and mental health.

The hypothesis:

We hypothesized that mouth breathing (MB) may induce AH, and that they interact with each other.

Evaluation of The Hypothesis:

AH may cause upper airway obstruction, which can induce the patient to switch from nasal breathing to mouth breathing (MB). However, MB does not involve the processes of warming, humidifying, and cleaning the inhaled air, which leads to changes in the oral environment and increases the risk of inflammation of the upper respiratory tract. This study discussed the relationship between MB and AH. The importance of this hypothesis is that attention should be paid to the status of MB or AH while treating them in order to block the interaction and thus improve the efficiency of treatment.

Published: December 2022

Introduction:

We aimed to systematically review the animal studies that have investigated the efficacy of periodontal ligament stem cells (PDLSCs) in bone regeneration.

Methods:

Web of science, Scopus, PubMed, Embase, Cochrane Library, and ProQuest were searched to September 2022 for animal studies investigating bone regeneration using PDLSCs.

Results:

Twenty studies were included. Calvaria and alveolar defects were treated with stem cells. The cells were mainly carried with hydrogel, hydroxyapatite, and collagen scaffolds. PDLSCs promoted osteogenesis compared with cell-free scaffolds, except in one study where biphasic calcium phosphate block scaffolds alone or with Bone morphogenic protein 2 had superior outcomes in calvaria defects. Controversial results were reported when comparing the osteogenic potential of PDLSCs and bone marrow stem cells. Two studies reported higher potential in BMSCs, and two others reported higher bone formation and more bone quality in PDLSCs.

Conclusion:

With the limitations of this study, PDLSCs might have promising potential to accelerate bone regeneration in artificial defects; however, due to high heterogeneity in the outcomes of the present studies, before moving forward to human experiments, further preclinical in vivo studies are needed.

Authors: Narayanan Sreenath , Hegde Mithra N. , Thirunarayanan Sembagalakshmi , Dsouza Teena Sheethal
Published: December 2022

Introduction:

Composite have evolved significantly due to the increase in the demand for a more esthetic and conservative approach in dentistry. Modifications have been made on the filler particle size and loading, followed by alterations in the resin matrix substance. Methacrylate-based composite with the addition of nanoparticles to the filler has been introduced in the market, providing improved esthetics and lower polymerization shrinkage. The present study was done to compare the fracture resistance of teeth restored using two newer methacrylate-based composite materials, along with the flexural strength of the composites.

Methods:

Sixty mandibular premolars were divided into two control groups of 10 teeth each and two experimental groups of 20 teeth. Group I − intact teeth with no preparations (n = 10), Group II − prepared but unrestored teeth (n = 10), Group III − teeth prepared and restored with a stackable nanohybrid methacrylate-based composite material (IPS Empress DirectTM), and Group IV − teeth prepared and restored with a packable submicron methacrylate-based composite material (Brilliant EverglowTM), respectively. The teeth were embedded in resin-filled PVC rings, and a compressive loading test was carried out for all groups at a cross-head speed of 0.5 mm/min. The flexural strengths of the two composite materials were also analyzed using three-point bending test using Universal Testing Machine. The statistical significance (P < 0.05) of the differences between the experimental groups was analyzed by ANOVA and Tukey post hoc test.

Results:

The mean fracture resistance was highest in Group IV (1877.37 ± 494.79) followed by Group III (1763.69 ± 392.51), Group I (1607.08 ± 283.48), and Group II having the least (1442.08 ± 373.66). The mean fracture resistance overall differed significantly between the four groups (P = 0.048). Tukey test showed fracture resistance differed significantly between Group II and Group IV (P = 0.042) and no significance among other groups.

Conclusion:

Fracture resistance was highest in the group restored with the packable submicron hybrid composite material. The packable submicron methacrylate-based composite material also showed higher flexural strength than stackable nanohybrid composite material.

Published: December 2022

Introduction:

Limited evidence is available on adhesive dentistry in the management of amelogenesis imperfecta (AI). The presentation, the conservative management with adhesive techniques, and the outcome of hypoplastic AI are discussed.

Case Report:

Autosomal dominant, hypoplastic AI was diagnosed, on a 36-year-old woman, presented with unesthetic teeth and a history of frequent decay with subsequent complications. Following the hygienic phase, stabilization of caries and root canal treatment (RCT) were done. Coronal restoration of endodontically treated teeth and light-cured direct composite veneering were done in the restorative phase. Surveyed crowns, mucosa-borne partial denture, and a resin-bonded bridge were prescribed in the prosthetic phase. The patient was pleased with the improved masticatory ability and esthetics.

Discussion:

A stepwise least invasive, yet esthetically acceptable treatment options based on adhesive techniques are successful in hypoplastic AI.

Authors: Nienaa Yasser A. , El Hadidi Abeer S. , Shawky Ghadeer A. , Elkholy Noha M.
Published: December 2022

Background

Vascular stiffness is common among patients with end-stage renal disease (ESRD). Circulating markers of bone formation play an important role in evaluating bone-mineral disease state as well as in predicting the risk of developing vascular calcification and hence, arterial stiffness.

Aims

This study aimed to assess arterial stiffness in maintenance hemodialysis patients using pulse wave analysis as an index of central and peripheral arterial stiffness and serum procollagen type I N-terminal propeptide (P1NP) as a marker for bone turnover.

Patients and methods

Fifty ESRD patients aged 18 years old or more who have been assigned to regular long-term hemodialysis were included in this study and subjected to complete history taking and physical examination and laboratory investigations including lipid profile, fasting plasma glucose level (mg/dl), serum creatinine, blood urea (mg/dl), serum phosphorus (mg/dl), serum calcium (mg/dl), P1NP (ng/ml), serum parathyroid hormone (PTH) (pg/ml), and serum bone-specific alkaline phosphatase (BALP) (U/l), and aortic pulse wave velocity.

Results

There was significant positive correlation between P1NP and PTH (P≤0.01) and between BALP and serum PTH (P≤0.01). There was significant difference between patients with low and high augmentation index regarding BALP (P=0.018).

Conclusion

ESRD patients have a high prevalence of vascular stiffness assessed by pulse wave analysis. There is a significant correlation between BALP and PTH and between P1NP and PTH. There is a relation between markers of bone formation and vascular stiffness.

Authors: Gholipur-Shahraki Tahereh , Vahdat Sahar , Seirafian Shiva , Pourfarzam Morteza , Badri Shirinsadat
Published: December 2022

Objective:

One of the most common diseases with high morbidity and mortality rates is chronic kidney disease. Cardiovascular disease affects most patients with chronic kidney disorders, particularly patients undergoing dialysis; hence, appropriate prevention and management approaches are essential. This study aimed to evaluate the reduction of inflammatory biomarkers, especially homocysteine, by omega-3 fatty acids in peritoneal dialysis patients.

Methods:

This study enrolled 60 peritoneal dialysis patients who met specified inclusion and exclusion criteria and were randomized to intervention or placebo groups. Omega-3 capsules were given at a dose of 3 g/d for 8 weeks. Inflammatory markers, including high-sensitivity C-reactive protein (hs-CRP), homocysteine, albumin, and lipid profile measured before and after the study.

Findings:

Results of this trial revealed that the levels of homocysteine, hs-CRP, and albumin did not change significantly during the study. Analysis of lipid profiles before and after intervention showed omega-3 has no significant effect on the level of total cholesterol or low-density lipoprotein cholesterol; However, the level of triglyceride reduced remarkably (P = 0.002). In addition, serum levels of high-density lipoprotein cholesterol increased at the end of the study (P < 0.001).

Conclusion:

Omega-3 does not seem to be able to change the inflammatory markers significantly, particularly homocysteine. More extensive trials must be conducted to better understand the impact of omega-3 on inflammatory and nutritional markers, particularly in peritoneal dialysis patients.

Published: December 2022

This study presents a low-cost smart pipeline inspection gauge (PIG) designed for pipeline defect (leakage) detection, and for quick data access and recovery for the purpose of analysis, utilizing locally sourced materials and off-the-shelf sensors and electronics. The PIG’s electronic circuit is designed to house the sensors and allow for easy reception and transfer of pressure measurements to the pipeline manager’s laptop via a WiFi module. A pressure sensor, a motion sensor, a wireless communicator, and an Arduino Microcontroller are utilized in the development of this PIG. The PIG was tested experimentally by being put through stationary, no load-no defect, and no load-defect tests respectively. The PIG was kept still during the stationary tests but was conveyed within a 160 mm diameter Polyvinyl Chloride (PVC) conduit with a length of 6.7 m for both the no load-no defect and no load-defect tests, using a 0.125 Hp direct current (DC) motor, with a gearbox attachment to pull from one end to the other. Using a WiFi module and the PuTTY program, the pressure values were retrieved. The test results revealed that P1 (front pressure) values were higher than P2 (rear pressure) values for the no load tests. P1 readings ranged from 1213 to 1214 Pa, with an average of 1213.86 Pa for the no load-no defect tests. The average P2 value was 1094.24 Pa, with a range of 1094.24 Pa to 1094.75 Pa. The pressure values for the no load-defect cases began at 1226.8 Pa and steadily decreased for the first 1.5 minutes, then remained at an average of 1214.2 Pa for the next 20 seconds until they arrived at the first defected point, where a value of 1216.1 Pa was recorded. The PIG traversed the pipeline until it had caught all of the pressure pulses at the defective sites. The higher pressure pulses (spikes) observed at the points of defects created along the pipeline in the experimental results from the no load-defect tests indicates that the Smart PIG was capable of detecting the created defects and demonstrated that the low-cost Smart PIG can be used to detect leakages on a pipe and can also be deployed in real life situations.
Goal programming and genetic algorithm in multiple objective optimization model for project portfolio selection: a review
Authors: Mogbojuri A. O. , Olanrewaju O. A.
Published: December 2022

Many scientific fields, such as engineering, data analytics, and deep learning, focus on optimization. Optimization problems are classified into two types based on the number of optimized objective functions: single objective and multi objective optimization problems. In this paper, a comparative review since 2000 using one of the deterministic and stochastic modelling approaches called goal programming (GP) and genetic algorithm (GA) in multi-objective optimization problem is discussed. This study gives a prime review of the application of GP and GA in various criteria of project portfolio selection problem. GP is a method for solving large-scale multi-objective optimization problems to assist decision makers in finding solutions that satisfy several competing goals. GA on the other hand are global meta-heuristic search algorithms that are used to provide approximation or optimal solutions to large-scale optimization problems. Of the 23 articles considered in this review showed that, from more than 100 projects, GA proved near optimal, feasible solution and efficient frontier in projects ranking, projects interaction and a preferred decision support tool of project portfolio selection. In addition, the two models select projects on risk-based approach, but GA proved to be more effective in terms of number of projects proposed, central processing unit (CPU) time and accuracy. The review concludes that, in multi-objective optimization model for project portfolio selection problems on a large-scale, very large or complex problems and less CPU time, GA is more effective than GP in multi-objective optimization problems. The review also showed gaps in previous studies of GP and GA application on project portfolio selection problem (PPSP). This review will aid scholars and demanding practitioners in gaining a broader understanding of goal programming and genetic algorithms in the context of project portfolio selection problems.
Variations in community perceptions of ecosystem services within the Tana River estuary, Kenya: Implications for ocean governance
Authors: Thoya Pascal , Owuor Margaret A. , Von Thenen Miriam , Omukoto Johnstone O.
Published: December 2022

Coastal communities in the Tana estuary, Kenya, rely on a variety of economic sectors linked to ecosystem services, including small-scale fisheries (SSF), commercial prawn fisheries, and tourism. Despite its environmental and social importance, the estuary has been negatively impacted by overexploitation, pollution, and climate change. As a result, developing integrated management approaches for this area is a priority. The integrated approach to ecosystem services (ES) evaluation has widespread support because it emphasizes people’s views of ecological value to human well-being and aims to provide a solution to the rapid depletion of our planet’s natural resources. This study applied mixed methods to understand the perspectives of the communities on ES. It was hypothesized that perceptions of ES differ across communities with different socioeconomic characteristics, and this hypothesis was tested in two communities (Ozi and Kipini) that share the same ecosystem but have different socioeconomic characteristics. Kipini is an area near the ocean, whereas Ozi is a rural area further upstream. Differences were noted in the valuation of cultural services, while there were similarities in provisioning and regulating services. Mangroves, other trees, and river systems were considered to have higher ES provision than the ocean, floodplains, and settlement areas. The Ozi community ranked the ocean higher than the Kipini community, even though Ozi was located further upstream from the ocean; consequently, the perception that communities benefit more from resources that they are close to could be false. The relevance of using social ES identification to determine the distribution of benefits from coastal ES is highlighted in this study and will be beneficial for informing decision-making and developing all-inclusive governance structures.

Review on Solar Drying in Nigeria
Authors: OKONKWO Henry , ERTEKİN Can
Published: December 2022

Nigeria, as one of the countries in the African continent has its challenges regarding to agricultural crops cultivation and its preservation methods. Traditional methods of preserving crops are commonly adopted by the local populace over solar dryer appliances. The reason for these includes being cheaper method, does not require much technical know-how, is easily learnable, the area for drying the agricultural crop produce being unlimited etc as when compared to solar dryers that needs materials to be fabricated, required little or medium knowledge of technical know-how, financial requirement for its fabrication which could range from few dollars to thousands of dollars. Solar dryer working principles, components, various classifications, and its mode of air movement and mode of heat transfer were discussed on this article. The article also reviewed some of the experimental researches on solar drying in Nigeria carried out by various scholars. The review of the published works on solar drying of various crops under different drying techniques were carefully studied. The results showed that, significant works on solar drying in Nigeria have been carried out even though its potential is greatly under-utilized due to various factors militating against it.

This research work determined the physicochemical, cooking and milling characteristics of four Nigerian rice varieties namely Illa from Southern, Abakaliki South-East, Jemila North and Ofada from West.The physiochemical, milling and cooking properties of rice are solely determining the preference, choice and economy of rice. The four rice varieties grown in different region in Nigeria were investigated for cooking, milling and physical, cooking and chemical characteristics. The result from axial dimension classified all the studied rice varieties as long grains. Illa rice recorded highest value (43.96 g) of 1000 grain weight while lowest value of 20.46 g was observed in Ofada rice. The variation in grain shape were not significant at (P>0.05) and all the tested varieties fall within the slender shapes. All the tested samples displayed good Milling behavior. Ofada rice elongated more than other varieties. The broken percentage was higher and lower in Illa rice (36.72%) and Abakaliki (28.78%) respectively. There were similarities in milling recovering of rice varieties, but Illa had highest expansion (swelling) capacity while Ofada had lowest swelling power. Amylose and gelatinization temperature showed a good relationship, Ofada rice with higher amylose content had lowest gelatinization temperature. The determined cooking time of the rice sample varied from 5.56 to 6.77 mins, Jemila rice will cook faster than other varieties. Illa rice had highest value (353.76%) of water absorption capacity, followed by Abakaliki rice with 185.76% Water Absorption Capacity and Ofada rice which had 158.62% WAC. The lowest value (155.60%) of Water Absorption Capacity was found in Jemila rice variety.
An AI and Cloud Based Collaborative Platform for PlantDisease Identification, Tracking and Forecasting for Farmers

Published: December 2022

Plant diseases are a major threat to farmers, consumers, environment and the global
economy. In India alone, 35% of field crops are lost to pathogens and pests causing lossesto farmers. Indiscriminate use of pesticides is also a serious health concern as many are toxic and biomagnified. These adverse effects can be avoided by early disease detection, crop surveillance and targeted treatments. Most diseases are diagnosed by agricultural experts by examining external symptoms. However, farmers have limited access to experts. Our project is the first integrated and collaborative platform for automated disease diagnosis, tracking and forecasting. Farmers can instantly and
accurately identify diseases and get solutions with a mobile app by photographing affected plant parts. Real- time diagnosis is enabled using the latest Artificial Intelligence (AI) algorithms for Cloud-based image processing. The AI model continuously learns from user uploaded images and expert suggestions to enhance its accuracy. Farmers can also interact with local expertsthrough the platform.
For preventive measures, disease density maps with spread forecasting are rendered from a Cloud based repository of geo-tagged images and micro-climactic factors. A web interface allows experts to perform disease analytics with geographical visualizations. In our experiments, the AI model (CNN) was trained with large disease datasets, created with plant images self-collected from many farms over 7 months. Test images were diagnosed using the automated CNN model and the results were validated by plant pathologists. Over 95% disease identification accuracy was achieved. Our solution is a novel, scalable and accessible tool for disease management of diverse agricultural crop
plants and can be deployed as a Cloud based service for farmers and experts for ecologically sustainable crop production.

Published: December 2022

As civilizations over the earth are becoming financially enhanced, people now possess their respective vehicles .With that progress accidents are likewise increasing. In earlier days, Accidents are not as much as today. The reason behind this is less population and awareness among the people. But in modern days and from the past decade the accidents have become common and are increasing continually with the rise of population. In addition people also become careless and indecisive. There
are numerous reasons that prompts accidents. To figure out this accident rate, we have framed a project which gestures the drivers to trace standards. As science and automations like IOT have become sophisticated, at this time there is a necessity of providing safety measures to restrict accidents.
The perception of tracking systems is not new and enterprises have made a lot of advancements in maximizing the technology. There are certain manual things to prevent accidents just like paying attention, beware of surroundings, inspect vehicles before and after, take breaks whenever needed but this is impossible to follow all these stuff in modern world. We designed a system that permits us to build a sensor network. The plan and the framework involves two areas where initially designating traffic signs by sorting the images and as well as during night and bad climate conditions it warns by a voice note. And secondly if a person feels drowsy our system signals the person with a blow sound. If any emergency takes place then an alert message and geographical location of the person will be sent to their emergency contact. This system is also
designed to help with providing an immediate medical help. If in case we are comfort and safe we can send a message by using a switch provided in that device.
Our device makes use of integrated Arduino that comprises of GSM primarily based module along with GPS module and Accelerometer Sensor. The objective is to build up a product that sends the area of accident vehicle automatically utilizing IOT. An alarming message which contains time and area is send to rescue offices for alleviation of the person.
Ethics, Alienation, and Ontology: The impossible is the starting point of each possible
Authors: Romeiro Hermeto João
Published: December 2022

The first quarter of the 21st century is reaching its end, and worldwide crises appear to become ubiquitous. Capitalist forces of destruction have not gone rogue, they merely represent the actualization of capitalist relations of exploitation. Notions of fettering fall prey to illusions, which overlook both particular historical moments and the essence of capitalist relations. In contrast, social emancipation presupposes an ontological understanding of human action. It is not enough to wish for a more humane society; both the limits of and potential for transformation must be understood. Based on Marx and Lukács, the ontological categories of possible and impossible, labour and teleology, are investigated, consequently, creating an opposing prerogative to capitalist naturalization and eternization. Capitalism is instead taken for what it is: a determined social, historical construction, thus, a superable social organization rather than a natural force. Insofar as the historical debacle of Marxism has provoked a methodological vacuum filled with relativism, contemporary critical analyses disaggregate into bourgeois isolated phenomena, becoming liberal assessments themselves. The concrete impact is not irrelevant: for they fight arguments in the fields chosen by capitalism; any perception of totality is rejected a priori; strategies to overcome capitalist challenges reproduce the conditions which create them, because it is assumed what needs to be explained. It appears urgent to reframe social critique within the frame of methodological orthodoxy. Marxist capitalist critique departs from ontological facts, for instance, labour. This means grasping both the totality and the ontological dimensions of particular forms, enabling effective strategies towards emancipation.
To use “he/she” or “they”: That is the question

This paper aims to underline the close connection between language and culture. Linguistic interaction is not only a series of sentences from a speaker to a hearer, but it also involves the cultural context which influences the interactants either to use political correctness or not. In recent years, native speakers as well as English teachers have been forced to deal with the abundance of terminology contrived so that people would not be offended by a ‘biased’ language which ignores/rejects their gender, ethnic origin, or sexual orientation. We try to show how sometimes an ‘unbiased’ language can have comic implications from a lexical-semantic point of view, but the goal of this discussion is to point out or even eliminate certain inequalities in society and to make the students understand these word-creations. The last part of this paper examines a questionnaire given to Romanian students which is meant to be a survey of their attitude towards the use of language with political correctness. The findings reveal the students’ opinions on gender, on societal restrictions and on (ab-)using language.
In the mind’s eye: Mental conceptualization of floods by the British and the Bulgarian media
Authors: Gorchev Ivaylo ,   Konstantin Preslavsky University of Shumen
Published: December 2022

From a cognitive linguistics perspective, the present study is aimed at the analysis of manifestations of metaphorical mental conceptualizations of flooding events in terms of war in the language used by the British and the Bulgarian journalists and the extent to which the implementation of the cognitive metaphor FLOODING CRISIS IS WAR differs in the media representations of the two countries. The corpus used for the research consists of 19 articles extracted from the electronic databases of four newspapers – two for the British discourse (the Guardian and the Independent) and two for the Bulgarian discourse (Monitor and Standart). A total of 33 example sentences have been extracted from the corpus (21 from the British media and 12 from the Bulgarian media) and they have been coded with respect to the mappings between the source and target domain of the cognitive metaphor. The results of the research show that the media both in the UK and Bulgaria rely on metaphorical projection from the domain of war when flooding crises are reported, which confirms the notion that metaphorical projection is a universal structural element of cognition.

Wastewater treatment plants contribute to the removal of pollutants from wastewater following the norms and regulations on the quality of the wastewater and therefore are an indispensable part of wastewater treatment and environmental protection. Each stage of wastewater treatment consumes a significant amount of energy. The need to meet rapid population growth and stricter conditions in terms of effluent quality requirements has led to an increase in energy consumption in wastewater treatment plants. Energy consumption is a bottleneck in wastewater treatment plants and, as the number of these plants in the world increases, the issues of reducing energy consumption and energy efficiency are beginning to attract attention. It also contributes to the cost increase in wastewater treatment plants. Analysis and prediction of energy consumption are key factors for energy savings. Energy consumption in wastewater treatment plants is affected by many factors. However, information on energy consumption and potential for energy recovery/production and energy efficiency in wastewater treatment plants remains very limited. This paper reviews the literature and analyzes the energy consumption in these plants and the possibility of increasing the energy efficiency of these plants through the use of renewable energy sources and energy recovery from the plant itself.

A new approach to efficient, faster, and intelligent hydropower plant (HPP) control, where constituent equipment is described with highly non-linear mathematical models based on the recommendation from the working group of IEEE on prime movers, is represented in this paper. HPP stability and high efficiency are important factors dependent on the dynamic changes in the energy system demands and the starting time of the plant because the obtained energy is very flexible to those changes in the energy system. This paper is shown and analysed the implementation of the artificial neural network-based controller with PID as an auxiliary controller which helped achieve better behaviour, faster plant stabilization, and operation. The benefits of new technologies and possibilities led to improvements in HPP control and faster system operation. This is achieved by using MATLAB® – Deep Learning Toolbox whereas the simulations are prepared in Simulink. Artificial Neural Networks (ANN) as a technique used in the HPP control systems have advantages in getting a stable and faster response but the complexity of the structure behind the neural networks (NN), meaning algorithms, number of hidden layers, training function, activation function can complicate and destabilize the process. In this paper, the focus is put on the mechanical power responses improvement and the advantages of implementing new technologies contrary to the problems that can occur by using them such as plant destabilization by implementing minor changes, fitting parameters, learning, and training processes, number of hidden layers/neurons, number of epochs, etc.

Dams and Hydropower plants in the Balkan region, especially in the countries of Ex-Yugoslavia, are coming to a period were reconstruction works have to be considered, to prolong their operational period and to improve their performance. The following paper represents a sublimate of series of steps taken for reconstruction and performance improvement of a Dam Bottom Outlet Regulation Gate. As the standards back in those days were slightly different from todays, and the equipment manufacture was also different, the main challenge was to take certain steps, such as analytical calculation approach, numerical CFD and FEA simulations and also mechanical reconstruction works, to make scope of workflows on the hydraulic gate, to improve operational range, reduce lifting loads and improve gate vibrations. Numerical simulations of the outflow conditions of the bottom outlet were carried out, and later were proved with drone footage to observe the outflow pattern. Besides, full dry and wet test measurements were made before and after reconstruction works, where significant performance improvement of the gate operation was achieved.
The Study of the Paleoclimatic Situation and the Problem of Population Mobility in the Eurasian Zone of the 10th -5th Centuries. BC.

Various natural phenomena, including climate change and various social manifestations resulting from them, have been in the focus of attention of specialists in various fields in recent decades.
Despite the available research, the works on climate change in the Armenian Highlands to a lesser extent present the broad issues of the relationship between society and nature, expressed in climate change, such as the movement of societies over a large area and the change in their way of life.
The purpose of this study is to present climatic changes in some zones of Eurasia at the end of the 2nd and the beginning of the 1st millennium BC. and consider their influence on the movements of different tribes and cultures.
Studies show that over the past 5000 years, the Eurasian zone of interest to us has experienced several cooling events, which in turn led to over-humidification. In other words, in the Eurasian zone at the end of the 2nd millennium BC. a situation of natural conditions was created, when the extraction of food became difficult. Therefore, it is quite logical that the tribes living in those areas, together or separately, had to leave their settlements in the hope of finding more favorable conditions.
Probably, climatic changes were also the reason that, judging by the archaeological material, some tribes, which were characterized by a new economy and culture, settled almost throughout the Caucasus. The combination of written and archaeological sources suggests that a special role among them was played by tribes known in professional literature as "Cimmerian and Scythian tribes".

The banking sector continues to face intense competitive pressures in a global economy where customer satisfaction, customer loyalty, and service quality continue to be critical factors. The aim of this study is to examine the relationship between service quality and customer satisfaction and customer loyalty. Additionally, in order to fill the empirical literature gap, the role of social media has been examined as a moderator. 230 retail banking customers from Pakistan were chosen as a representative sample. Using the structured questionnaire, convenient (non-probability) sampling was employed to gather primary data from the target population. A statistical analysis of the collected data was conducted using Structural Equation Modeling - Partial Least Squares (SEM-PLS). The findings of the study revealed that customer loyalty is significantly influenced by service quality and customer satisfaction. Furthermore, social media also influences the correlations between service quality and customer satisfaction with consumer loyalty. This study will provide retail banking management and strategists with various useful insights about how to manage service quality and customer satisfaction in relation to customer loyalty.

Introduction: Malnutrition is common among hospitalised patients, with poor follow up of nutrition support post-discharge. Published studies on the efficacy of ambulatory nutrition support (ANS) for malnourished patients post-discharge are scarce. The aims of this study were to evaluate the rate of dietetics follow-up of malnourished patients post discharge, before (2008) and after (2010) implementation of a new ANS service, and to evaluate nutritional outcomes post-implementation. Materials and Methods: Consecutive samples of 261 (2008) and 163 (2010) adult inpatients referred to dietetics and assessed as malnourished using Subjective Global Assessment (SGA) were enrolled. All subjects received inpatient nutrition intervention and dietetic outpatient clinic follow-up appointments. For the 2010 cohort, ANS was initiated to provide telephone follow-up and home visits for patients who failed to attend the outpatient clinic. Subjective Global Assessment, body weight, quality of life (EQ-5D VAS) and handgrip strength were measured at baseline and five months post-discharge. Paired t-test was used to compare pre- and post-intervention results. Results: In 2008, only 15% of patients returned for follow-up with a dietitian within four months post-discharge. After implementation of ANS in 2010, the follow-up rate was 100%. Mean weight improved from 44.0 ± 8.5 kg to 46.3 ± 9.6 kg, EQ-5D VAS from 61.2 ± 19.8 to 71.6 ± 17.4 and handgrip strength from 15.1 ± 7.1 kg force to 17.5 ± 8.5 kg force; P <0.001 for all. Seventy-four percent of patients improved in SGA score. Conclusion: Ambulatory nutrition support resulted in significant improvements in follow-up rate, nutritional status and quality of life of malnourished patients post-discharge.

Published: December 2022

Introduction: Singing in psychotic patients has received little attention in the psychiatric literature. In this preliminary study, we test the hypothesis that manic patients sing more than schizophrenic patients (SPs). Materials and Methods: Manic patients and SP inpatients and outpatients were interviewed using a semi-structured questionnaire which included questions on musical interests, and how much they felt like singing prior to their most recent admission to hospital. They were asked if they were willing to sing during the interview and responses were observed. Results: Of the 69 manic patients and 68 SPs interviewed, manic patients were more likely to report singing than SPs (76% vs 24%) prior to their most recent admission to hospital. There was a trend for manic inpatients to be more willing to sing during the interview. Conclusion: Increased singing is suggested as a useful symptom and sign in patients suffering from a manic illness.

Psychiatry is often fraught with uncertainties and complex situations which give rise to particular ethical issues. However, there is still a dearth in formal training in psychiatric ethics. In this perspective by a clinician, researcher and bioethicist, a case is made for a special status in medical ethics and the need for the incorporation of a structured educational programme in psychiatric ethics during residency training. This educational process should also include the acquiring of certain virtues and competencies.
