Authors: Sitkina E. V. , Smirnova E. S. , Isaeva E. R.
Published: May 2022

The study is devoted to the study of the emotional state of people in the conditions of self-isolation during the pandemic of a new coronavirus infection. The online study involved 380 «conditionally healthy» respondents aged 18 to 60 years. A special questionnaire was developed; to assess the emotional state of the subjects, the Hospital Anxiety and Depression Scale (HADS) and the Bass-Darkey aggressiveness level questionnaire were used. Only 45–54% of respondents tried to comply with the sanitary regime, men violated the established requirements more often than women. No clinical symptoms of anxiety or depression were found. The level of anxiety reached subclinical values in women. At the same time, there was an increased level of aggression (verbal and indirect) and irritation, an increase in the integral indicators of aggressiveness and hostility. These emotional manifestations characterize the well-known reactions of a person’s mental maladaptation in difficult life situations.

Authors: Ovchinnikova A. O. , Mikhalchenko S. V. , Chernova O. E.
Published: May 2022

The purpose of the study: to analyze the microbiota of the vagina and urine culture in HIV-infected women, depending on the absence or presence of pre-pregnancy preparation with and without a partner.

Materials and methods. 90 women of reproductive age with stage 3 and 4A of HIV infection participated. Vaginal fluid and urine were inoculated on artificial nutrient media, identification using MALDI ToF mass spectrometry. The Kraskel-Wallis criterion, Mann-Whitney criterion and Simpson index were used to compare the groups.

Results and their discussion. It was found out that in women without pregravidar preparation, the total bacterial mass of lactobacilli is significantly lower (p=0.004), the total number of lactobacilli is lower (p=0.005); the bacterial mass of staphylococci and streptococci is greater (p=0.009); the total number of microorganisms seeded is higher (p=0.004) against the background of increased viral load (p=0.001); Enteroccocus often acts as the cause of asymptomatic bacteriuria faecalis with a viral load above the detection threshold (p=0.009). Thus, we show that the lack of pre-pregnancy preparation in HIV-infected women is associated with vaginal mesocenosis and the development of asymptomatic bacteriuria.

The purpose statement is to analyze the socio-demographic, clinical, epidemiological, and behavioral characteristics of patients with only HIV infection and those co-infected with HIV and Tr. pallidum, which are under supervision in St. Petersburg GBUZ «Center for the Prevention and Control of AIDS and Infectious Diseases».

Material and methods. The data of outpatient cards of 588 patients who were registered in the dispensary at the St. Petersburg Central Clinical Center in the period from 2018 to 2020 were studied, and the data of the cards of males (435 people) were selected. Patients were divided into two groups: with HIV monoinfection (198 people) and with a combination of HIV infection and syphilis (237 people).

Results. Patients co-infected compared with HIV-only patients were less likely to have higher education, were less likely to be married, were diagnosed with HIV infection more often at self-report and during routine examination, there were more men who hade sex with men (homosexual), and bisexual men. Co-infected patients were less likely to have used drugs in the present or in the past and were primarily infected with HIV through sexual contact. They were diagnosed mainly with early forms of syphilis. In patients with coinfection, concomitant diseases of the kidneys, cardiovascular, endocrine systems were often detected, and a high comorbidity with chronic hepatitis B was also noted.

Conclusion. The identified socio-demographic, clinical, epidemiological and behavioral characteristics of men with HIV + syphilis coinfection indicate the need for more active work aimed at popularizing barrier contraception among men, especially MSM and prone to bisexual contacts; when syphilis is detected in HIV-infected patients, conduct a thorough examination of all organs and systems, extraordinary for the presence of viral hepatitis.
Public Participation in Decision–Making Towards Accountable and Transparent Governance in Vietnam
Authors: Phan Huong Thi Lan
Published: May 2022

Public participation is one of the key elements in ensuring democratic values in any country. People have the right to participate in the decision-making process and express their ideas and needs. While Vietnam has developed a legal framework for legislation that stipulates the obligation of drafting committees to open draft laws for public comment (Law on Promulgation of Normative Legal Documents 2015, amended 2020). However, Vietnamese citizens and legal entities still cannot participate in the drafting of laws and policies because many obstacles exist: (1) the law does not clearly define the authorities’ obligations to respond to people's comments/feedback; (2) there is a lack of an effective mechanism to ensure that individuals and organizations can participate in the decision-making process, especially in the pandemic situation - Covid 19; (3) there is a lack of an effective mechanism for policy impact assessment. Thus, the question is how to promote public participation in the decision-making process to ensure that policy meets the interests of the public and the needs of the people. This paper aims to assess the current situation of public participation in decision-making and propose solutions to develop active and meaningful participation of people in formulating problems, planning, implementing, and tracking the implementation of policies towards accountable and transparent governance in Vietnam.

Published: May 2022

The development of technology brings changes in human life, and the shift of most human activities to cyberspace is now a challenge for every country in the world. Cyber-attacks are crimes that have developed rapidly with the development of information communication and technology (ICT). Due to its impact, cyber-attacks can be considered as a crime called a crime of aggression. The focus of this paper is to determine the urgency of regulating cyberattacks as a crime of aggression and to find out the extent to which the international community has made cybercrime the focus of contemporary crime research, which is referred to as a crime of aggression. This paper shows that international cooperation is needed to create an international regime that is respected and universally accepted by the international community in relation to cyber-attacks, which can also be referred to as crimes of aggression. It is because cyber-attacks in its nature are transnational crimes and need a cooperation such as the framework of ASEAN to deal with.

Authors: Solórzano Salas María Julieta
Published: May 2022

El grupo de docentes de Educación Especial requiere formación en educación sexual, ya que, al ser un apoyo, debe garantizar el acceso al aprendizaje de toda la población estudiantil. La investigación recopila la perspectiva del docente formador universitario en Costa Rica en la formación de docentes de Educación Especial desde el método fenomenológico. Las docentes formadoras realizan su praxis docente según su formación. La investigación y la experiencia con el estudiantado con discapacidad les ofrecen herramientas valiosas para guiar al profesorado de Educación Especial. En su praxis, favorecen en el profesorado en formación el desaprender las huellas que se construyen a partir de posturas conservadoras y dogmáticas en la comprensión de la sexualidad humana. El profesorado formador debe tener espacios para la reflexión de su propia práctica docente y es necesario profundizar en este tipo de investigaciones.
On the three lowest spin states of Na13+. Hybrid DFT and Benchmark CASSCF(12,12)+CASPT2 studies
Authors: Alanís-Manzano Emiliano , Ramírez-Solís Alejandro
Published: May 2022

The three lowest spin states (S=0,1,2) of twelve representative
Na isomers have been studied using
both, KS-DFT via three hybrid density functionals, and benchmark
multireference CASSCF and CASPT2 methods with a couple of Dunning’s
correlation consistent basis sets. CASSCF(12,12) geometry optimizations
were carried out. Since 12 electrons in 12 active orbitals span the
chemically-significant complete valence space, the results of the
present study provide benchmarks for
Na. The CASPT2(12,12)/cc-pVTZ*
lowest energy structures are three nearly degenerate singlets (S=0): an
isomer formed from two pentagonal bipyramids fused together (PBPb), a
capped centered-squared antiprism [CSAP-(1,3)] and an optimum
tetrahedral OPTET(II) structure, the last two lying 0.88 and 1.63
kcal/mol above the first, respectively. The lowest triplet (S=1) and
quintet (S=2) states lie 4.33 and 3.77 kcal/mol above the singlet global
minimum, respectively. The latter is a deformed icosahedron while the
former is a CSAP-(1,3). The flatness of the potential energy surface of
this cluster suggests a rather strong dynamical character at finite
temperature. Prediction of the lowest energy structures and electronic
properties is crucially sensitive both to non-dynamical and dynamical
electron correlation treatment. The CASPT2 vertical ionization energy is
3.66 eV, in excellent agreement with the $3.6 \pm 0.1$
eV experimental figure. All the isomers are found to have a strong
multireference character, thus making Kohn-Sham density functional
theory fundamentally inappropriate for these systems. Only large
multiconfigurational complete active space self-consistent field
(CASSCF) wavefunctions provide a reliable zeroth-order description; then
the dynamic correlation effects must be properly taken into account for
a truly accurate account of the structural and energetic features of
alkali-metal clusters.

Ultrasound Based Three-Dimensional Mapping for Safely Performing Intracardiac Echocardiographic Left Atrial Appendage Occlusion Device Implantation.
Authors: Elsayed Mahmoud , Nellaiyappan Madhan , Doyle Mark , Alhuneafat Laith , Slemenda Colin , Liu Emerson , Lasorda David , Thosani Amit
Published: May 2022

Background: Left atrial appendage occlusion (LAAO) has historically been
performed using intraprocedural transesophageal echocardiography (TEE)
and fluoroscopy. Multiple recent reports have described the feasibility
and advantages of utilizing two-dimensional intracardiac
echocardiography (ICE) for LAAO. However, in inexperienced hands, safe
manipulation of the ICE catheter in the left atrium (LA) can be
challenging. Objective: To assess the feasibility and efficacy of
three-dimensional (3D) ICE mapping in guiding LAAO device implant
compared to standard TEE imaging. Methods: We retrospectively included
patients who underwent LAAO in our institution from January 2017 and
October 2021. We compared baseline demographics, intraprocedural data,
post-procedural complications, and outcomes. P= value of <0.05
was considered significant. A linear regression model was performed
using ICE and TEE as dependent variables to model contrast dose.
Results: 130 patients underwent LAAO device implantation, of which 57
underwent ICE guided LAAO and 73 underwent TEE guided implantation.
There was no difference in baseline demographics or post-procedural
outcomes between both groups. There was no difference in the total
procedure time between ICE and TEE groups, 86 (72-107) and 83 (72-111)
minutes (p=0.65), respectively. Conversely, total fluoroscopic time was
significantly shorter in ICE arm 7.8 (5.6-11), compared to TEE arm 12.9
(10.5-17.6) (p= <0.001). In patients undergoing LAAO device
implantation using 3D ICE technique, with each additional ICE-guided
procedure, the contrast dose decreased by 0.87 mL (correlation r =
-0.48, p<0.001). Conclusion: 3D ICE is safe and feasible in
guiding LAAO device implantation. When compared to TEE technique, total
fluoroscopic time was shorter. Additionally, with more procedures
utilizing 3D ICE, contrast dose decreased in a linear fashion.
PHARMACOKINETICS AND CLINICAL OUTCOMES OF TOBRAMYCIN IN ADULT CYSTIC FIBROSIS PATIENTS WITH ACUTE PULMONARY EXACERBATION
Authors: Thirion Daniel , Koloskoff Kevin , Caissy Jean-Alexandre , Matouk Elias , Marsot Amélie
Published: May 2022

Background Acute pulmonary exacerbation (APE) in cystic fibrosis
patients is frequent and associated with a decline in pulmonary
function, quality of life and survival. Tobramycin is often used in
regimens requiring activity against Pseudomonas aeruginosa,
however, an important number of centers do not use official dosing
recommendation. The current dosing strategy may be suboptimal.
Methods This retrospective cohort analysis was performed on all
adult cystic fibrosis patients that were admitted at a tertiary care
facility for treatment of APE and with tobramycin between January 2015
and December 2019. The primary objective was to evaluate the predictive
performance of previously published pharmacokinetic (PK) models and,
secondly, to evaluate potential factors that impact clinical outcomes.
Clinical outcomes were only evaluated in a sub-group of patients with
cultures positive for P. aeruginosa. Results A total of
202 APEs from 51 patients were included in the PK analysis. Two
population PK models were assessed and failed to fit our data. In all,
109 APEs from 32 patients were included in the clinical analysis.
Factors that significantly impacted clinical outcome were the number of
prior APE and concomitant antibiotics. Clinical success rate for
regimens containing at least one active agent against P.
aeruginosa according to its susceptibility was 67%. Conclusion
Population PK models evaluated in this study cannot be used to perform
simulations. A new model must be developed for our population. In
patients positive for P. aeruginosa, Ceftazidime in combination
to tobramycin may be a superior regimen. APE history remains predictive
for outcomes in adult CF patients treated for an APE.

Due to economic trends in the building industry, the investigation of the residual bearing capacity of reinforced concrete elements has been receiving more and more attention in recent years. Studying the effect of damage on the bearing capacity of reinforced concrete elements is one of the main themes of investigation in this field. Results of 4 reinforced concrete beams’ testing are proposed, one of which was the control one (tested without damages) and three- typically damaged in the compressed zone at different load levels. As a result, the most crucial effect was detected by the type of damage, load, and neutral axis position change. In addition, research results demonstrate an increase of 3.8% in reinforced concrete beams bearing capacity if they are damaged under the load, compared with the unloaded damaged reinforced concrete beams.

Feminism as Depicted in Mahfouz’s Palace Walk, Gordimer’s None to Accompany Me, and Coetzee’s Disgrace
Authors: Fahad M Alashjaai Nouf
Published: May 2022

Feminism is among the common practices in the modern world and aims to proclaim gender equality. Mahfouz, Coetzee, and Gordimer are among the African Noel laureates who pioneered what could be termed a rebellion toward normality. Amina, a protagonist of Palace Walk, presents a character who purposes to challenge the biased and male-centric conventions. For instance, her choice of going to the mosque alone, in the absence of her husband, was a practice that was not acceptable in the Muslim culture; nevertheless, she took the bold step. On the other hand, Lucy is presented as a chain breaker who goes against the system of oppression by choosing a black husband. The choice of Lucy to leave her husband and start living with Rapulana, who was a black man, was a courageous move, and from that angle, she can be depicted as an agent of change. The same character is portrayed in Vera, who betrays her husband for another man, Ben – it is worth noting that Vera chose a black man, thus entering into an interracial relationship as in Lucy’s case. Such characters played a significant role in challenging what has been termed normalThe use of art presents a new perception of fighting for women’s rights non-violently. This study aims at answering questions on what causes gender inequality and how art, such as the use of novels, can be used to end this social issue.

Published: May 2022

The article is focused on computer modeling of the sea cargo front of export coal terminal seaside in Anylogic environment. The main stages of development and formalization of the model have been analyzed. Using the statistical data on Rosterminalugol, JSC and Daltransugol, JSC, the dependences of the deadweight of bulk carriers on their length, width and draft were determined. A general classification of bulk carriers has been formed according to transport and technological characteristics. On the basis of statistical data, the number of bills of lading and/or grades of coal loaded onto bulk carriers at sea coal terminals have been assessed. Requirements for the selection of ship-loading equipment are formulated. The main types of berthing ship-loading machines used today are determined. Most export coal terminals use ship-loaders of the coordinate type with a lifting fixed boom. The choice of layout and technological scheme of the simulated sea front was carried out. The sea export coal terminal of Rosterminalugol, JSC in the seaport of Ust-Luga was taken as a basis. There is given a description of constructing a discrete-event simulation model of the sea cargo front in Anylogic software. It has been stated that the developed simulation model allows calculating the performance of the sea cargo front with several different layout options: with 1 or 2 berths, as well as with different capacity of cargo-loading machines. The results of the model operation make it possible to select a front layout option with the required annual throughput of berths and without exceeding the specified average time of vessel stay under loading. There are shown the basic principles of the model operation, explained the functionality of all logic blocks of the simulation model algorithm. The configuration control elements of the cargo front model have been presented, as well as the results of the work and conclusions.

Published: May 2022

The aim of the article was the intraindividual evaluation of reaction time at the Men’s World Athletics Championships from 1999 to 2019. We generated the rating of sprinters from the age point of view with comparison of two periods with different false start rules. In the result section, we analysed the sprinters that took part at WCH at least 3 times and appeared in the final. We assessed the reaction speed from the aging point of view, or more different false start judging conditions. The results shows that the stricter start judging rules in sprint disciplines did not have a significant influence on the reaction time. We also confirmed a research that the sprinters over 30 years old sprinters can achieve very low reaction time at the start. Reaction abilities can be improved by regular and systematic training, so it is necessary to pay attention to them in the training process and focus on their monitoring and subsequent improvement.
Post-Pandemic Policy Priorities for Financing Sport and Physical Activity in the EU
Authors: Kornbeck Jacob
Published: May 2022

The most sport-relevant points in a resolution adopted by the European Parliament with regard to the use of post-Covid-19 relief funds from the general budget of the European Union (EU) are highlighted. Members of Parliament (MEPs) have indicated unambiguous preferences for part of the EU funding to be directed towards the need of youth and sport, the latter in particular at grassroots level, and the resolution represents a piece of soft law which should be drawn upon to interpret relevant legal acts such as the relevant financial instrument(s). The article goes on to discuss the implications in relation to traditional sport policies, as opposed to more participation-driven policies following the health-enhancing physical activity (HEPA) paradigm.
Entropy generation analysis in a gasket plate heat exchanger using non-spherical shape of alumina boehmite nanoparticles
Authors: Nogueira Élcio
Published: May 2022

The analysis deals with the thermo-hydraulic performance of a Gasket Plate Heat Exchanger used for cooling vegetable oils with a water-ethylene glycol 50% and volume fractions of non-spherical nanoparticles mixture as a refrigerant. The heat exchanger has 75 plates with a chevron angle equal to 30º. The Reynolds number of the refrigerant varies from 80 to 1530. The Reynolds number of the sunflower vegetable oil is fixed and equal to 30. The non-spherical nanoparticles used for analysis are platelet, cylindrical and brick types. Graphical results are presented for global heat transfer coefficient, heat capacity ratio, heat transfer rate, outlet temperatures, thermal and viscous entropy generation rate, and Bejan thermodynamic number. The results obtained allow us to conclude that it is possible to work with low relative flow rates using non-spherical nanoparticles, emphasizing platelet nanoparticles. The entropy generations analysis shows that very high flow rates of the refrigerant dissipate much of the energy in viscous form and do not contribute to oil cooling, with a consequent increase in the heat exchanger operating costs.
Crisis Aspects of the Covid-19 Pandemic in the Social Sphere and Secondarily in Economic One
Authors: Wójcicki Włodzimierz
Published: May 2022

Subject and purpose of work: The study focuses on the social and economic impact of the COVID-19 pandemic globally and regionally, particularly in Poland.

Materials and methods: Based on the literature, the historic origins of various pandemics have been presented as evidence for their cyclicity.

Results: An analysis of current COVID-19 reports serves to verify the hypothesis that the economic outcomes are secondary to the social outcomes, which generally distinguishes the current crisis from other known economic and financial crises of the market origin. The recovery from the economic crisis leads to the strengthening of the private sector, but the public sector, especially health care and education, is of particular significance in the pandemic crisis.

Conclusions: The need to develop instruments of fighting the crisis has been indicated, with special emphasis on logistics. The pandemic may solidify many years of cultural, social and economic changes, so far rather modestly foreshadowed by various signs.
The Evolution of China’s Economic Engagement in Central and Eastern Europe
Authors: Bharti Mukesh Shankar
Published: May 2022

Subject and purpose of work: The purpose of this study is to assess the economic partnership between China and Central and Eastern Europe (CEE). It evaluates the economic policy since the cooperation in the region began, as the 17+1 process. The study evaluates the success and failure of China’s economic engagement in the 17 CEE countries and the Balkan region. This article explores how the relationship was made stronger in CEE countries for economic development. It looks at diplomatic ties, trade knot and economic initiatives, and it examines China’s relations with other CEE countries. The article aims to examine the geographical distribution of China’s economic influence on the CEE countries.

Materials and methods: Content analysis is widely used as a comparative technique by the press, media, think tanks and communication. There are official statistics from a wide range of institutions (The China Observers in Central and Eastern Europe (CHOICE), the IMF, the OECD, the European Commission, the European Union, Statistics CEE countries and the European External Action Service).

Results: The latest result indicates that Chinese economic policy is not achieving more success than the expected objectives in CEE countries.

Conclusions: China’s economic impact on CEE countries is relatively small. Central and Eastern European countries are highly dependent on trade and investment relations with developed states, mainly EU members, while China accounts for a minor share.

Authors: Figus Alessandro , Spulber Diana
Published: May 2022

The pandemic crisis has coincided with a time of global economic crisis. The education system has suffered from this double impact: the simultaneous closure of schools and universities and a significant worsening of the business and productivity system. Digitalisation in the education process started in the far past, but it has become a priority with the pandemic. The use of digital tools in the educational process ensured that the latter did not come to a complete standstill during the pandemic. Although digitalisation is seen as a possible solution to the problems facing schools, it can also be seen as a factor in widening the gap between rich and developing countries. The article proposes a reflection about education during the pandemic and the digitalisation process of schools in all its facets and at alle education level.
A Simplified Numerical Approach to Predict Bearing Capacity of Soil for Shallow Foundation
Authors: Das Jayanta Kumar , Bharali Biswadeep
Published: May 2022

For the safe and economical design of a foundation under any civil engineering structure, precise estimation of the ultimate bearing capacity (UCB) of soil beneath the foundation is of significant concern. Numerous researchers have contributed to these field and proposed theories and equations to predict the subsoil’s ultimate bearing capacity. But determining the approximate value of bearing capacity depends on soil type and its characteristics, groundwater table, types of loads, loaded area of footing, depth of footing, etc. Moreover, deciding the appropriate depth and size of footing is a crucial task. This paper aims to propose a simplified numerical approach to predict the bearing capacity of soil beneath the foundation (NABBSF) using MATLAB software. Considering shear failure and excessive settlement criteria, this model will predict the ultimate, safe, and allowable soil bearing capacity beneath an isolated footing at different depths. The validity and accuracy of the proposed model is verified by comparing it with real field data.

The single pile is a structural element that has an important role in supporting any part of the superstructure. This paper adopted three dimensional finite element modelling by using ANSYS to discover the influence of soil size domain on pile diameter, pile length, load eccentricity and torsion magnitude. One type of soil was used and described by Drucker-Prager model. The numerical analysis has been performed to show how the variation in soil size domain effects on the behaviour of single pile under torsion load. The procedure which is adopted in the investigation depends on fixing all variables and changing one variable to show the impact of this variable on the pile response considering soil domain variation. From the investigation, it is obvious that the pile diameter, eccentricity and torsion load have a major influence on the pile response, while the pile length has a minor influence on the pile response. Here, the increase in pile diameter reduces the load transfer to the soil; also the increase in eccentricity increases the load transfer to the soil while the increase in soil domain reduces the pile response. When the torsion load increases the pile response increases too. The pile response refers to displacement, rotation, shear force and bending moment.

Due to increasing in urbanization, agricultural and various human activities are being increased which caused the contamination of surface water and ground water. Present demand of drinking water is not sufficient which should be safe and clean but it is contaminated now a day’s coming from different sources. Various treatments and methods are adopted to upgrade the quality of drinking water. Water should be free from the various contaminations viz. Organic and Inorganic pollutants, Heavy metals, Pesticides etc. as well as all its parameter like pH, Conductivity, Calcium, Magnesium, Total Hardness, Carbonate, Bicarbonate, Chloride, Total Dissolved Solid, Alkalinity, Sodium Potassium, Nitrate should be within a permissible limit. For this purpose, different samples were collected from different sources. Category 1: piped water, Category 2: Boreholes with hand pump average depth is 30m, Category 3: Society supply line, Category 4: Simple open hand dug wells that do not sealed walls average depth 5m, Category 5: Surface water. These samples were analyzed for their physical-chemical and microbiological quality (pH, Conductivity, Turbidity, Hardness & Total dissolved solids) in order to identify the rate of contamination and suggest appropriate solutions. Different diseases are accrued in human body which is identified due to the contaminated water. By chemical testing, it can be identified and then suggested some methods of treatment to purify the water for drinking purposes. All parameters are confirmed by comparing with World Health Organization (WHO) standards. Results concluded that quality of drinking water have been adequate of category 3 in which drinking water coming from society treatment plant but category 2 also lies within the acceptable range.

To reduce the consumption of cement in construction industry has been a hot area of consideration now days due to high evolution of CO2 gases during its production. Since decades efforts are made to replace cement with cementitious materials; minerals, agricultural, industrial by products etc. A few are fly ash, ground granulated blast furnace slag, silica fume, rice husk ash etc. These cementitious materials are often adopted as partial replacement of cement. However, their effectiveness and suitability as cementitious material depends upon their properties and the source of the production. Pakistan is an agricultural country and one of the major crops is Rice crop. It produces a substantial amount of rice husk during the processing g of the rice. A substantial amount of Rice Husk Ash (RHA) is produced on the burning of rice husk used as fuel in the rice mills while generating steam for parboiling process of rice grains. This ash causes the environmental problems also if not dumped properly. RHA is believed to have siliceous properties which may be used as supplementary cementitious material in concrete. As the suitability of supplementary cementitious materials is dependent upon the source of rice husk, temperature of burning of husk, its fineness and other properties. This study is focused on to determine the effect of rice husk ash produced by burning of the rice husk obtained from the local rice mills. Experimental investigation carried includes the determination of workability and compressive strength of concrete with different dosage of RHA from 5% to 30% with an increment of 5% tested at 1day, 3days, 7days and 28 days of the age of concrete. The results are compared with corresponding concrete without RHA and tested at the same ages. The results show the reduction in both the parameter; workability and compressive strength due to RHA particularly at its higher dosage beyond 10% by weight of cement.

Water quality modeling has been shown to be a useful tool in strategic water quality management. In this study, HEC-RAS model was employed to assess the water quality of Soan River. The model was calibrated and validated successfully by evaluation through NSE and R2 values. The simulated BOD and DO values were found to be in agreement with the measured values. Furthermore, the findings revealed that the Soan River was polluted downstream of the Kaak Bridge due to industrialization and urbanization along the River’s banks. The HEC-RAS model is a useful tool for managing water quality and making decisions. Furthermore, many situations were investigated in order to provide appropriate options for River water quality management. Sewage effluents, agricultural runoff and industrial effluents were found to be responsible for the high nutrient levels in the River which in turn reduced DO levels and increased BOD. The requirement for comprehensive integrated models that can be used to make defensible decisions is now important for the long-term management of aquatic ecosystems. The uncertainty surrounding the outcomes of integrated modelling studies makes it difficult for water resource managers to execute them.
A Review of Defence Pretrial Disclosures Within the Case Management Theory of Criminal Proceedings in Ghana
Authors: Tufuor Isidore Kwadwo
Published: May 2022

This article examines the concept of defense disclosures within the theory of managerialism in criminal proceedings in Ghana. Through a doctrinal and comparative legal analysis with the English jurisdiction, it finds that in substance, the requirement of defense disclosure seeks to move the criminal process from its core protectionist ideology that insulates the accused from matters of proof toward a managerial process informed by objectives of truth-finding, trial efficiency and case management. Ironically, this new direction in the criminal trial process is in practice denounced as being at odds with the procedural due process values that shield the accused from matters of proof and pretrial disclosures. The problem is that unlike in England where the move towards defense disclosures is informed by a clear policy change, the managerial policy introduced by the Judiciary in Ghana is not grounded in any articulated theory or policy direction. While pursuing a path of ensuring effective criminal adjudication through mutual disclosures by the parties, it is important to find a proper balance between the denounced but yet adopted procedural concept of defense disclosures and the highly valued protectionist rights of the accused.

This study evaluated the influence of acute water ingestion and maintaining an upright posture on raw bioimpedance and subsequent estimates of body fluids and composition. Twenty healthy adults participated in a randomized crossover study. In both conditions, an overnight food and fluid fast was followed by an initial multi-frequency bioimpedance assessment (InBody 770). Participants then ingested 11 mL/kg of water (water condition) or did not (control condition) during a 5-minute period. Thereafter, bioimpedance assessments were performed every 10 minutes for one hour with participants remaining upright throughout. Linear mixed effects models were used to examine the influence of condition and time on raw bioimpedance, body fluids, and body composition. Water consumption increased impedance of the arms but not trunk or legs. However, drift in leg impedance was observed, with decreasing values over time in both conditions. No effects of condition on body fluids were detected, but total body water and intracellular water decreased by ~0.5 kg over time in both conditions. Correspondingly, lean body mass did not differ between conditions but decreased over the measurement duration. The increase in body mass in the water condition was detected exclusively as fat mass, with final fat mass values ~1.3 kg higher than baseline and also higher than the control condition. Acute water ingestion and prolonged standing exert practically meaningful effects on relevant bioimpedance variables quantified by a modern, vertical multi-frequency analyzer. These findings have implications for pre-assessment standardization, methodological reporting, and interpretation of assessments.

In recent years, due to the occurrence of water shortage and drought problems, particularly in arid and semi-arid regions of the world, new methods to reduce evaporation from the surface of dam reservoirs, lakes, and other water-free surfaces are investigated. This study aimed to use hydrophobic bentonite to reduce water evaporation from water surfaces, on a laboratory scale, and field conditions for the first time. Bentonite initially became hydrophobic by stearic acid (SA). Under such conditions, hydrophobic bentonite floats on the surface of water and forms a thin coating layer. The produced hydrophobic bentonite had a contact angle of 150°, indicating its superhydrophobicity. Evaporation reduction was measured under laboratory and field conditions and it was compared to hexadecanol as the reference material. The results demonstrated that the hydrophobic bentonite efficiency under laboratory conditions was similar to that of hexadecanol and prevented water evaporation by 36%. However, under field conditions, hydrophobic bentonite and hexadecanol efficiencies were 40% and 23% to reduce evaporation for 30 days, respectively. In terms of stability, hexadecanol needed to be re-injected after three days, while hydrophobic bentonite was stable and remained on the surface for more than 100 days under laboratory conditions and for more than 15 days under field conditions without needing re-injection. This coverage with method can be used to reduce evaporation from lakes, tanks, and reservoirs of small dams.
