ABSTRACT

The water supply network is a crucial component of urban construction and plays a pivotal role in the normal operation of the city. The complexity and periodicity of pressure variations in the water supply networks pose significant challenges to traditional prediction models. In this study, we introduce a novel short-term pressure prediction model, termed the 1DCNN-GRU-multi-head attention (CGMA) model, which incorporates a multi-head attention mechanism alongside an integrated network consisting of one-dimensional convolutional neural networks (1DCNNs) and gated recurrent units (GRUs). Initially, the model employs a 1DCNN network to extract features from the pressure data. Subsequently, the extracted features are input into the GRU neural network, leveraging its long-term dependency capabilities to improve prediction accuracy. Then, the attention mechanism is incorporated into the GRU component to highlight key information, enabling the model to focus on more important data features, thereby improving the prediction performance. We implemented this model in a real urban water distribution system equipped with five pressure sensors. The model achieved a mean absolute error of 0.00197 and a root mean square error of 0.00262. When compared with alternative approaches, our method demonstrated superior predictive performance for pressure data, thereby confirming its efficacy in practical applications.

Published: July 2024

Background:
Chagas disease has an ineffective drug treatment despite efforts made
over the last four decades. The carbonic anhydrase of Trypanosoma cruzi (α-TcCA) has emerged
as an interesting target for the design of new antiparasitic compounds due to its crucial role in parasite
processes.

Objective:
The aim in this study was identify potential α-TcCA inhibitors with trypanocidal activity.

Methods:
A maximum common substructure (MCS) and molecular docking were used to carried
out a ligand- and structure-based virtual screening of ZINC20 and MolPort databases. The compounds
selected were evaluated in an in vitro model against the NINOA strain of Trypanosoma
cruzi, and cytotoxicity was determined in a murine model of macrophage cells J774.2.

Results:
Five sulfonamide derivatives (C7, C9, C14, C19, and C21) had the highest docking scores
(-6.94 to -8.31 kcal/mol). They showed key residue interactions on the active site of the α-TcCA
and good biopharmaceutical and pharmacokinetic properties. C7, C9, and C21 had half-maximal
inhibitory concentration (IC50) values of 26, 61.6, and 49 μM, respectively, against NINOA strain
epimastigotes of Trypanosoma cruzi.

Conclusion:
Compounds C7, C9, and C21 showed trypanocidal activity; therefore, these results
encourage the development of new trypanocidal agents based in their scaffold.

Published: July 2024

Background:
Introducing pilot protection in active distribution networks containing PV
can improve the reliability and selectivity of protection. However, the basic communication facilities
of the existing distribution network make it difficult to meet the requirements of data synchronization,
and the PV T-connection to the network leads to sudden changes in the impedance
angle.

Methods:
Therefore, pilot protection of a negative sequence and additional network considering
PV is proposed. The scheme is based on the feature that the PV model only outputs positive sequence
components after a fault. For asymmetrical faults, the negative sequence impedance detected
at both ends of the protection is utilized to construct a comparative negative sequence impedance
protection criterion. For symmetrical faults, the voltage characteristics of the faulty additional
network are utilized to construct a protection criterion.

Results:
Finally, an actual distribution network model with PV is constructed in PSCAD to verify
the effectiveness and reliability of the protection method.

Conclusion:
The protection method is selective and reliable and is not affected by high penetration
rate and PV fault characteristics.

The world and nearly all our health care system were confronted by a significant threat which was declared by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Determining the SARS-CoV-2 or COVID-19’s prognostic and modifiable measures surely would largely contribute to outcome improving despite the deficiency of causative therapy that affected nearly 200 million people, 3.5 million fatal incidences, and it is still airborne. The research in hand examined probable relations between the levels of vitamin D (VitD) and immunological markers. Hence, a sample of 200 lecturers and students from Cihan University-Erbil were assigned, (150 males, 50 females) whom ages were between 22 to 25, with some respondents were treated from a previous COVID-19 infection. The results showed that 98 (or 49%) of the 200 samples had Covid-19 infection. Males 60/98 had a greater prevalence rate (61%), whilst females 38/98 had a lower rate (39%). According to immunological ELISA results, every patient had positive IgG antibodies and negative IgM antibodies. Compared to the healthy group, the serum levels of IgE rose considerably in Covid-19 patients. However, when compared to the healthy group, the serum level of vitamin D3 in the Covid-19 recovered patients showed a considerable reduction. The mean results for hematological parameters indicated a non-significant increase in the number of red blood cells relative to the healthy group, but a significant increase in the WBC count, Hb concentration, and platelets. Thus, the result indicates the necessity for interventional studies on vitamin D supplementation in SARS-CoV-2 infected persons by showing a correlation between vitamin D deficit and WBC count during COVID-19 recovery.

Published: July 2024

Abstract
The public sector of the Federation of Bosnia and Herzegovina (FBiH) from the aspect of complexity and comprehensiveness, includes all levels of government established within the state government, public companies, and the insurance system including: pension, health and social. The importance of performing duties and obligations in a transparent manner, and the possibility of detecting warning factors for corrupt activity are especially important in the public sector.
Corrupt activities at all levels of the state structure of Bosnia and Herzegovina (BiH), as well as fraudulent behaviour and abuses within it, are precisely the consequences of the complexity of the state system, and the impossibility of efficient and rational use of public funds. Adequately organized, in accordance with the law, and accepted as such by employees within a certain public sector organization, internal auditing contributes to more efficient operations and prevention of corrupt practices. The aim of the subject research is to look at the process of functioning of the internal audit in the public sector of FBiH in the field of prevention of corrupt activities. The results of the research indicate the non-functioning and non-establishment of the internal audit in the manner specified by law, as well as the inadequate implementation of its recommendations, degrading and derogating its role, importance and contribution in the prevention of corrupt activities in the public sector of FBiH.
