The construction sector plays a vital role in Malaysian economy and a very significant part of its' sustainable development. CPM is a professional who monitors all works in the construction project from top to bottom. The role of CPM is very important to identify their range of top responsibilities which might have different levels of priorities depending on the type of project.

Methodology/Technique - There are several of them identified from the literature. The objective of this study was to identify which responsibilities were among the top ones, and to find out whether they have any kind of inter-relationship between them. The Experts were chosen for interview and questionnaire survey. A comparative analysis was performed by using Expert Choice, which gave the rankings.

Findings - A qualitative judgment showed that there were indeed some responsibilities which can play significant role. However, it was tough to single them out in a clear ranking, nor was it seemed primarily necessary. Rather, a group of responsibilities appeared to describe the phenomenon more clearly.

Novelty - The study also showed how some of these responsibilities seemed to be closely interlinked and why they actually need to be together cohesively.

ON THE APPOINTMENT OF THE MODERN RUSSIAN CRIMINAL PROCESS
Authors: Maksimov O.A.
Published: June 2021

The article examines the purpose of the modern Russian criminal procedure as a way of implementing the constitutionally defined tasks of the state. With a variety of approaches to defining the subject of research, one can single out two interrelated, but also mutually exclusive ideas that underlie the understanding of the purpose of criminal proceedings - for the implementation of criminal law (combating crime, organizing criminal prosecution) or for protecting the rights and freedoms of persons involved in criminal proceedings. legal proceedings. The prevalence of one of them depends on the type of process, while they cannot exist on equal terms due to the opposite methods of implementation in a particular criminal proceeding. With the priority of one of the ideas, the entire criminal process is built according to the type of designated purpose, and the second idea is one of the means of achieving it. The purpose of the criminal procedure follows from the main tasks of the state. It is concluded that in connection with the clearly established in the Constitution the basic values subject to state protection, the only purpose of the modern Russian criminal procedure is to protect human rights and freedoms, regardless of his procedural status in criminal proceedings.

Authors: Cao Yang , Nogawa Kenta , Kobayashi Nobukiyo , Masumoto Hiroshi
Published: June 2021

We present a general synthesis of transition metal difluorides (TMF2)–carbon nanocomposite films by magnetron co-sputtering the Fe/Co and polytetrafluoroethylene (Teflon) targets. The composites consist of binary TMF2 (TM = Fe, Co) nanoparticles with a crystallite size of ∼8 nm immersed in a carbon matrix. The antiferromagnetic nature of TMF2 nanoparticles with the Néel temperature T
N of 40 K (TM = Co) and 78 K (TM = Fe) is confirmed. The ability to create the sputter-deposited TMF2–carbon nanocomposites may not only allow for possible energy applications but also provide a platform for investigating the particulate disordered antiferromagnets.

Published: June 2021

There is limited information about the characteristics of faecal sludges in ordinary pit latrines. Knowledge of the physico-chemical and biological characteristics of pit sludge from different layers of the pit apart from providing an indication of the nature of pit contents endeavoured to provide information and decision support for managing pit latrines during their normal lifespan. Therefore, this paper was aimed at investigating the physico-chemical and biological characteristics of pit sludge samples to equip latrine owners with environmental and health implications of this sludge. Legislation that establishes regulations specifically for the treatment and discharge, enduse, or disposal of faecal sludge is therefore essential. Thus, faecal sludges sampled from ten (10) pit latrines were subjected to laboratory analyses with particular reference to selected parameters. From the study, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total solids (TS), moisture content, suspended solids (SS) and volatile solids (VS) showed decreasing trend throughout as the pit depth increased. Temperature presented double scenarios, increasing initially and decreasing afterwards with the highest values within 0.4m to 0.6m pit depth in all the pit latrines. Efforts to understand and mitigate the health effects of particulate matter (PM) air pollution have a rich and interesting history. This review focuses on six substantial lines of research that have been pursued since 1997 that have helped elucidate our understanding about the effects of PM on human health. There has been substantial progress in the evaluation of PM health effects at different time-scales of exposure and in the exploration of the shape of the concentration-response function. There has also been emerging evidence of PM-related cardiovascular health effects and growing knowledge regarding interconnected general pathophysiological pathways that link PM exposure with cardiopulmonary morbidity and mortality. Despite important gaps in scientific knowledge and continued reasons for some skepticism, a comprehensive evaluation of the research findings provides persuasive evidence that exposure to fine particulate air pollution has adverse effects on cardiopulmonary health. Although much of this research has been motivated by environmental public health policy, these results have important scientific, medical, and public health implications that are broader than debates over legally mandated air quality standards.

A flux-controlled memristor using complementary metal–oxide–(CMOS) structure is presented in this study. The proposed circuit provides higher power efficiency, less static power dissipation, lesser area, and can also reduce the power supply by using CMOS 90nm technology. The circuit is implemented based on the use of a second-generation current conveyor circuit (CCII) and operational transconductance amplifier (OTA) with few passive elements. The proposed circuit uses a current-mode approach which improves the highfrequency performance. The reduction of a power supply is a crucial aspect to decrease the power consumption in VLSI. An offered emulator in this proposed circuit is made to operate incremental and decremental configurations well up to 26.3 MHZ in cadence virtuoso platform gpdk using 90nm CMOS technology. proposed memristor circuit has very little static power dissipation when operating with ±1V supply. Transient analysis, memductance analysis, and dc analysis simulations are verified practically with the Experimental demonstration by using ideal memristor made up of ICs AD844AN and CA3080, using multisim which exhibits theoretical simulation are verified and discussed.
Who Cares? ―The COVID-19 Pandemic, Global Heating and the Future of Humanity1
Authors: Tännsjö Torbjörn
Published: June 2021

The COVID-19 pandemic has engendered unprecedented drastic and costly measures to obviate the threat. Will something similar happen in relation to global heating? No, this is not likely. Mainly this has to do with a difference in the nature of collective action. Nation states protect their respective populations against the virus. With regard to global heating, we are facing the tragedy of the commons. No global government assumes responsibility for our common future. However, there may be another and further explanation lurking behind political inaction: many people, including our politicians, think that it does not matter if humanity goes extinct. It does matter, however. Strangely enough, the view that it matters is questioned by many important philosophers in the past and in the present, and it is hence controversial. Yet, it should be our common-sense stance to the problem. It is of the utmost importance that there will be sentient happy life on the globe for an indefinite time. Theoretically speaking, in order to recognize this, we need to accept some “total” view, implying what has been called the repugnant conclusion. Practically speaking, we should go to great length to rescue our human civilisation, even if this means that, for a while, we must endure all sorts of hardships such as a global enlightened despotism, or worse—a situation of life boat ethics.

Robin Dembroff’s “Escaping the natural attitude about gender” replies to my “Are women adult human females?”. This paper responds to Dembroff’s many criticisms of my arguments, as well as to the charge that “Are women...?” “fundamentally is an unscholarly attempt to vindicate a political slogan that is currently being used to undermine civic rights and respect for trans persons”. I argue that Dembroff’s criticisms fail without exception, and explain why the claims about my motives are baseless.

With the widespread of the pandemic COVID-19, commonly known as Corona virus the normal lifestyle of
people across the globe has been disturbed and jumbled up. Humans who are social beings are asked to
maintain social distance from one another as no cure has been found yet and this is the only preventive step. Many countries have
been put on lockdown, where people are asked to stay at home with minimal movement in the city only in cases of necessity and
emergency. For certain section of people it is possible to work from home and manage normal routine but the major distress has
been seen in the life of daily wage workers and labourers. In this distressing situation of social and economic crisis there has also
been increase in the number of cases reported for domestic violence and abuse. The study aims to understand the nature of distress
leading to domestic violence, is it a way of coping: a displacement of stress. Secondary data was collected by analysing the reports
by 'National Commission for Women' (NCW); 'Ministry of Women and Child Development'; 'United Nations' and 'World Health

Authors: Tamilmathy E. , Kalaimathi B. , Kulandaiammal M. , Sharmila B.
Published: June 2021

OBJECTIVE: This study aimed to assess the knowledge of newly diagnosed COVID-19 positive patients about the
medications in the management of COVID-19 and and to evaluate their level of anxiety and the mental health status.
METHODOLOGY :This observational study was done with newly diagnosed COVID-19 patients attending Outpatient Department of a Covid
screening Centre, Chennai for a period of 2 months from November to December,2020. .Individuals who fullled the inclusion criteria were
selected and they were assessed for their knowledge about medications in the management of COVID-19 using a questionnaire through
telephonic conversation. Graph Pad prism 7 was used for descriptive analysis.kruskal wallis test was used to to compare and determine which
group dominates the other.
RESULTS : Majority of patients were having adequate knowledge about COVID-19 through mass media(48%)and Health care workers(35%).
Higher educational status of participants were associated with better knowledge scores(p<0.01).All participants were having <3 in Covid
severity scoring. Of the total 200 patients, high proportion of patients were aware of kabasura kudineer and multivitamin tablets containing zinc
supplements as they were issued to them by healthcare workers .Among them 39% answered that siddha medicines are the best choice in the
management of COVID-19 and 55%answered that taking multivitamin tablets containing zinc supplements aids in the improvement of health
status. About 35% were aware of antibiotics such as Azithromycin and 19% of patients answered that there is no need of any medications for
COVID-19.Few invalid responses related to the use of herbal food products like garlic were noted. Using GAD-7 scoring, among the newly
diagnosed COVID-19 positive patients, 69% felt anxious.
CONCLUSION: As COVID-19 is a pandemic, it is essential to improve the knowledge about medications among general public for proper
management of illness. Most of the participants are having average knowledge about basic management of the illness, which reects the
responsibilities and steps taken by Health care workers, government and media.
A STUDY TO CORRELATE TOTAL CALCIUM AND GLYCATED HEMOGLOBIN IN TYPE-2 DIABETES PATIENTS.
Authors: Indhumathi V , Priyatharshini M. , Muraliswaran P. , Dhanoushyaa S
Published: June 2021

Background: The risk for developing diabetic complications are related to glycemic control which is measured by
estimating the glycated hemoglobin (HbA1c) level. Calcium increases the GLUT 4 activity. Change in calcium alters the
insulin receptor phosphorylation, and decreases the activity of glucose transporter
Objective: To nd out the correlation between serum Calcium and glycated Haemoglobin in Type 2 Diabetes Mellitus patients.
Materials And Methodology: A cross sectional study which included 100 type 2 Diabetes mellitus patients, divided into 2 groups based on
HbA1c levels. Group 1 : Type 2 Diabetic patients with HbA1c more than 7 percent and Group 2 : Type 2 Diabetic patients with HbA1c less than
7 percent. Total calcium level was correlated with glycated hemoglobin level. Statistical analysis was done using unpaired t test.
Result: The mean value of serum total calcium was lower in the diabetic group whose HbA1c was > 7 (p value – 0.000) when compared to the
diabetic group whose HbA1c was <7. A strong negative correlation (r = -0.391) between calcium and HbA1c in the T2 diabetic patients with
HbA1c >7 (p = 0.000) was observed.
Conclusion: Alteration in calcium levels will have adverse effects on insulin secretion and release. Estimating the level of calcium becomes
important to know the status of insulin in diabetic patients and correlating the levels of HbA1c and Serum Calcium in Type 2 DM patients, can
monitor the levels of glycemic control and the risk of development of complications. Calcium supplementation to the diabetic patients can help
in better glycemic control and prevent diabetes related complications
A Single-Switch-per-Bit Topology for mmWave and THz Reconfigurable Reflective Surfaces
Authors: Theofanopoulos Panagiotis
Published: June 2021

We present novel multi-bit unit-cell topologies for
reconfigurable reflective surfaces –RRSs– (e.g., reflectarray
antennas) with compact designs for millimeter-wave and terahertz
(mmWave/THz) applications. Typically, mmWave/THz RRSs
utilize one or multiple single-pole-single-throw (SPST) switches
leading to single- or dual-bit modulated surfaces. These surfaces
utilize the switches to manipulate the phase of the imping waves,
beamforming the reflected waves to the desired direction. As such,
RRSs are leveraged either for imaging or wireless communication
applications, which typically require the formation of a single
beam (no grating lobes) and high gains. The gain and quantization
lobe levels of an RRS is strictly related to the number of phase bits
utilized in the unit-cell. Explicitly, more phase bits lead to lower
quantization errors and better maximum gain/aperture efficiency.
However, increasing the number of phase bits requires more SPST
switches integrated within the unit-cell, leading to complex designs
with high RF losses. Herein, we present, for the first time, RRSs
with up to 4 phase quantization bits (16 states) that maintain one
switch-per-bit topology thus retaining a low-complexity design.
The proposed RRSs is presented alongside a series of analytical
and full-wave simulated results.
Balancing Biases and Preserving Privacy on Balanced Faces in the Wild
Authors: Robinson Joseph , Fu Yun , Timoner, Samson , Henon Yann , qin Can
Published: June 2021

There are demographic biases in current models used for facial recognition (FR). Our Balanced Faces In the Wild (BFW) dataset serves as a proxy to measure bias across ethnicity and gender subgroups, allowing one to characterize FR performances per subgroup. We show performances are non-optimal when a single score threshold is used to determine whether sample pairs are genuine or imposter. Across subgroups, performance ratings vary from the reported across the entire dataset. Thus, claims of specific error rates only hold true for populations matching that of the validation data. We mitigate the imbalanced performances using a novel domain adaptation learning scheme on the facial features extracted using state-of-the-art. Not only does this technique balance performance, but it also boosts the overall performance. A benefit of the proposed is to preserve identity information in facial features while removing demographic knowledge in the lower dimensional features. The removal of demographic knowledge prevents future potential biases from being injected into decision-making. This removal satisfies privacy concerns. We explore why this works qualitatively; we also show quantitatively that subgroup classifiers can no longer learn from the features mapped by the proposed.
Filter Distortions in Ultra High-Throughput Satellites: Models, Parameters and Multicarrier Optimization
Authors: Colin Tony , Delamotte Thomas , Knopp Andreas
Published: June 2021

Ultra high-throughput satellite systems are expected to play an essential role in future beyond 5G and 6G networks. These systems must remain as flexible as possible to adapt to heterogeneous traffic demands, while also delivering the highest possible rate for dedicated services. Satellites flexible payloads are increasingly employing wideband output multiplexers. In this context, it is now more important than ever to evaluate frequency-dependent degradations on multicarrier signals. In particular, it is critical to characterize the distortions entailed by the output multiplexers filters. In this paper, models are presented and novel formulas are derived to determine the carrier-to-interference ratio resulting from these distortions. Derivations are oriented towards the applicability of either high-accuracy (e.g., for link budget) or low-complexity calculations (e.g., for real-time carrier allocation). The influence of key parameters such as the optimal decision instant, symbol rate and roll-off factor is thoroughly analyzed. Furthermore, formulas are evaluated in a practical scenario: the dynamic carrier allocation optimization. They are combined with efficient optimization algorithms to obtain the best performance based on user fairness. Relevant metrics such as accuracy, complexity and allocation gain are also investigated. In the end, the application of the proposed formulas and algorithms leads to a significant allocation gain that is increasing with the number of carriers. The feasibility of real-time dynamic carrier allocation to further increase the capacity of the next generation of satellite systems is emphasized.

Authors: Bashar Abul , S Smys
Published: June 2021

The hybrid system configuration is used for meeting the thermal and electrical load demands of an off-grid network simultaneously with the model proposed in this paper. Li-ion battery, Micro Gas Turbine (MGT), wind turbine and solar photovoltaic configurations are analyzed. Hybrid Optimization of Multiple Electric Renewables (HOMER) software is used for estimating utilization of various strategies for power management, recovered waste heat and excess energy in the model. The heating demand is met and examined by the thermal load controller with and without the options of waste heat recovery. The hybrid system hardware components are sized, compared and analyzed based on cyclic charging (CC) and load following (LF) dispatch strategies. Various electrical to thermal load ratio are considered for examining the system performance. Various uncertainties and their effects are reported on comparison of grid-connected and stand-alone options. The hardware components are reduced in size thereby appreciable cost benefits are observed in the results. In the optimized hybrid system, the renewable energy fraction is increased causing high renewable penetrations and the CO2 emission is reduced by a large value. For all the configurations analyzed, several environmental and cost benefits are offered by the CC strategy.
