Opis:
Parkinson’s disease is associated with memory loss, anxiety, and depression in the brain. Problems such as poor balance and difficulty during walking can be observed in addition to symptoms of impaired posture and rigidity. The field dedicated to making computers capable of learning autonomously, without having to be explicitly programmed, is known as machine learning. An approach to the diagnosis of Parkinson’s disease, which is based on artificial intelligence, is discussed in this article. The input for this system is provided through photographic examples of Parkinson’s disease patient handwriting. Received photos are preprocessed using the relief feature option to begin the process. This is helpful in the process of selecting characteristics for the identification of Parkinson’s disease. After that, the linear discriminant analysis (LDA) algorithm is employed to reduce the dimensions, bringing down the total number of dimensions that are present in the input data. The photos are then classified via radial basis function-support vector machine (SVM-RBF), k-nearest neighbors (KNN), and naive Bayes algorithms, respectively.

Opis:
An attempt has been made to synthesize the aluminium based ex-situ (Al-SiC) and in-situ (Al-TiB2) formed metal matrix composites with varying weight percentage of reinforcement contents such as 4wt.%, 6wt.% and 8wt.%. Synthesized composites were subjected to a cold extrusion process followed by heat treatment according to the ASTM B 918-01 standards. The mechanical properties of in-situ composites were evaluated as per the ASTM guidelines and compared with ex-situ formed composites and base metal properties. Superior properties were noticed in the in-situ formed composites and the mechanical properties such as yield strength, Ultimate tensile strength (UTS) and Hardness for both ex-situ and in-situ composites were found to increase with increasing the reinforcement addition. Cold extruded Al-8 wt.% SiC composite properties such as hardness, yield strength and UTS are 87 RB, 152 MPa, 216 MPa respectively. Whereas, for Al-8 wt.% TiB2 composite, the corresponding properties are 94 RB, 192 MPa, 293 MPa. The morphology of the composites is analysed by Optical and Scanning Electron Microscopic (SEM) whereas presence of reinforcement particles such SiC and TiB2 along with intermetallic phases Mg2Si and Al5FeSi are confirmed by EDX, XRD and Element Mapping analyses.

Opis:
The main objective of this study was to estimate the environmental and health risk of the Šar Mountains (Kosovo) for depleted uranium contamination. The risk assessment of the contamination is needed since, in the spring of 1999, conflict with bombarding took place in the territory of the Western Balkans, during which depleted uranium ammunition was used. In Serbia and Montenegro, such tests were performed; based on them, some territories were decontaminated. Šar Mountains is particularly important as it is one of the few water-rich areas in Kosovo. Therefore, soil and water samples were taken from characteristic places in the Šar Mountains aquatorium. Tests of the samples were performed under well-controlled conditions. The measurement uncertainty was less than 5%. Based on the obtained results, it was concluded that there was no contamination of the Šar Mountains with depleted uranium. This conclusion can be extended to the broader area around the Šar Mountains, as it is a safe area surrounded by high mountains

Opis:
Studies on serum interleukin (IL)-31 levels in dogs with atopic dermatitis (AD) and their correlation with disease severity are limited. To the author’s knowledge, there are no studies that measured serum IL-31 in dogs treated with lokivetmab injections, a selective inhibitor of this key cytokine in pruritus. The aim of the study was to evaluate serum IL-31 levels in dogs treated with lokivetmab and correlate it with the severity of canine atopic dermatitis using the pruritus visual analog scale (pVAS) and canine atopic dermatitis extent and severity index (CADESI-04). Ten client-owned dogs diagnosed with AD received two injections of lokivetmab four weeks apart. Disease severity was assessed using the pVAS and CADESI-04 scores before and after both injections. In addition, canine serum IL-31 levels were measured at the same moments. Serum IL-31 was detected in all dogs in the study. There was a significant reduction in pVAS scores and serum IL-31 after administrations. However, there was no difference in CADESI-04 scores, and there was no significant correlation between CADESI-04 scores and serum IL-31 in dogs diagnosed with AD. Nonetheless, a significant positive correlation was observed between the pVAS scores and serum IL-31 levels with lokivetmab therapy, which reinforces the role of IL-31 in the pathogenesis of pruritus in dogs with AD. The data presented here provide further evidence that IL-31 is directly involved in pruritus pathogenesis in dogs with AD. In addition, blocking IL-31 has a significant antipruritic effect, but has no influence on skin lesion severity and extension.

Opis:
This paper presents a method of synthesizing copper powders by electrochemical method with the use of a rotating working electrode. The influence of the rotation speed of the working electrode, the current density, the concentration of copper ions, and the addition of ethylene glycol on the shape, size, and size distribution of the obtained powders were investigated. Properties of the synthesized powders were characterized by scanning electron microscopy (SEM) and X-ray powder diffractometry (XRD). It has been shown that it is possible to obtain copper powders with a size of 1 µm by an electrochemical method using the rotary cathode, in sulphate bath with addition of ethylene glycol as a surfactant. Increasing current density causes a decrease in the average size of the obtained powder particles. The addition of 2.5% of ethylene glycol prevents the formation of dendritic powders. The change in the concentration of copper ions in the range from 0.01 to 0.15 mol/dm3 in the electrolyte did not show any significant effect on the size of obtained particles. However, higher concentrations of copper limiting the presence of dendritic-shape particles. Changing the speed of rotation of the electrode affects both the size and the shape of synthesized copper powder. For the rotational speed of the electrode of 115 rpm, the obtained powders have a size distribution in the range of 0-3 µm and an average particle size of 1 µm. The particles had a polygonal shape with an agglomeration tendency.

It is assumed that in the case of contact languages, it is the nonverbal context of use of these languages that may be the key factor in determining the nature of each language. Contact languages, perhaps even to a greater extent than larger or more common, the so-called national languages, may establish the identity of the speech communities that use them. The text presents also selected ways in which contact languages arise, adding to the types of languages known to science, such as endogenous and exogenous contact languages, a new name for the category of languages, which are isogenic contact languages.

Opis:
Background. Globally, alcohol consumption is the major cause of mortality and disease. Future health and life quality may also be affected by early initiation of alcohol consumption. It is a cross-sectional design for a research survey. Objective. This study aimed to investigate alcohol drinking behavior, the effects of alcohol consumption, and factors linked to alcohol drinking behavior among 410 secondary school students in grades 1-3 in the province of Nakhon Si Thammarat in southern Thailand. Material and Methods. A simple sample was selected from a stratified random sample of 210 individuals. The data collection instrument was a questionnaire comprised of five sections and 78 items in total. The index of item objective congruence (IOC) of 0.90 and the reliability of 0.74 was used to evaluate the tool’s quality. To analyze the data, descriptive statistics and chi-square statistics were employed. Results. The results of the study showed that a total of 40.0% of the participants had previously consumed alcohol, that men were more likely than women to drink (54.8%), that beer was the most popular alcoholic beverage (57.7%), that most people drank alcohol at night while at home (47.6%) and with friends (83.6%), the majority of participants (13.9%) drank alcohol one to three times per week, and their attitudes toward alcohol were moderate (85.7%). Religion, knowledge about alcohol use, and the amount of money received each month from habitat for humanity were not found to be linked to drinking alcohol. Conclusion. The conclusion is that the use of alcohol by students is influenced by a wide variety of circumstances. Health professionals, educational institutions, and relevant agencies should use these factors to promote alcohol use prevention behaviors and formulate guidelines and measures to prevent this by designing an effective prevention program to reduce the alcohol use behaviors of children and young people in the appropriate manner.

Opis:
Cluster analysis can be defined as applying clustering algorithms with the goalof finding any hidden patterns or groupings in a data set. Different clusteringmethods may provide different solutions for the same data set. Traditionalclustering algorithms are popular, but handling big data sets is beyond theabilities of such methods. We propose three big data clustering methods basedon the firefly algorithm (FA). Three different fitness functions were definedon FA using inter-cluster distance, intra-cluster distance, silhouette value, andthe Calinski-Harabasz index. The algorithms find the most appropriate clustercenters for a given data set. The algorithms were tested with nine popularsynthetic data sets and one medical data set and are later applied on two bad-minton data sets with the intention of identifying the different playing stylesof players based on their physical characteristics. The results specify that thefirefly algorithm could generate better clustering results with high accuracy.The algorithms cluster the players to find the most suitable playing strategyfor a given player where expert knowledge is needed in labeling the clusters.Comparisons with a PSO-based clustering algorithm (APSO) and traditional al-gorithms point out that the proposed firefly variants work in a similar fashion asthe APSO method, and they surpass the performance of traditional algorithms.

Opis:
This paper proposes two new methods of measuring the viscoelastic parameters of materials. The methods are based on the composite beams’ resonant frequencies measurement. The Young moduli and loss factors of the components are determined by measuring the frequency response of a composite beam twice, each time with different layer thickness ratios. A system of two equations is obtained, from which Young’s moduli of the composite components are calculated. Similarly, two obtained equations determine the loss factors. The results obtained by the proposed methods are compared with those obtained by standard methods and then validated by experiments and FEM simulations. It was noted that the developed models, as well as the standard ones, are highly sensitive to the precision of the samples (material trimming and the way of joining the composite elements). The proposed methods prove to have an advantage over the standard ones in the matter of more frequent measurement criterion fulfilment. The acknowledged criterion represents the existence of a sensible solution insensitive to measurement errors. This criterion, which assures that the results are not prone to errors (for example negative loss factors) is met in 100% of cases in one of the methods, compared to 65% for standard methods.
