Cloud Point Extraction Combined with Electrothermal Atomic Absorption Spectrometry
Authors: Hagarová Ingrid
Published: July 2022

Nowadays, a considerable number of various separation/preconcentration procedures coupled with electrothermal atomic absorption spectrometry (ETAAS) can be found in the published literature. Among separation techniques, cloud point extraction (CPE) has found its regular use in ultratrace analysis of elements. This review offers a more detailed look to the coupling of CPE and ETAAS, especially to the parameters affecting ETAAS quantification of a selected element. Publications, where this combination of separation technique and quantification method is used, describe an achievement of quantitative extraction recoveries, an acceptable precision and low limits of quantification (LOQs) for different (ultra)trace elements in various complex matrices. These results lead to the conclusion that the developed procedures have a great analytical potential for reliable quantification of (ultra)trace elements, even when complicated matrices containing various components are to be analyzed, which is supported by papers mentioned in this review.

Published: July 2022

Office workers often work overtime, stay up late, lack of sleep, and have poor sleep quality, resulting in a high liver index. Abnormal liver function is the main risk factor for modern social civilization diseases and chronic diseases. The purpose of this study was to explore the relationship between sleep time, sleep quality, and liver function, and analyze the collected data from the Taiwan MJ Health Examination Center from 2001 to 2010. This study mainly found that participants with extremely poor sleep had 1.128 times the chance of developing abnormal liver function compared with participants with good sleep. At the same time, it was found that the average daily sleep time of fewer than 4 hours, compared with people who sleep for 7-8 hours, the probability of abnormal liver function is 1.206 times. Therefore, good sleep quality and proper sleep time will reduce the occurrence of abnormal liver function.

Published: July 2022

Introduction: A metastatic tumor of the ovary known as Krukenburg Tumor (KT) is a mucin-rich signet-ring adenocarcinoma that arises from a gastrointestinal site in most cases and from other sites in less proportion. We describe a rare case presenting a Krukenberg tumor secondary to pancreatic ductal adenocarcinoma. Case Presentation: A 51-year-old female, who started her current condition 6 months ago, with 15 kg of weight loss, accompanied by nausea, vomiting, early satiety, and constipation. Computerized tomography showed dependent mass involving the body and tail of the pancreas with solid and cystic components, highly suggestive of a primary tumor as well as peritoneal carcinomatosis and a left ovarian mass, tumor (Krukenberg) as a first possibility. A laparoscopy was performed. The final pathology report was a pancreatic ductal adenocarcinoma with metastases to the ovary from the left salpingectomy. Conclusion: Pancreatic cancer presenting as Krukenberg tumor of the ovary is rare and easily misdiagnosed as primary ovary carcinomas, which leads to missed surgical opportunities. Resection of ovarian metastases combined with chemotherapy treatment may increase the overall survival even in patients with advanced pancreatic ductal adenocarcinoma.

Water is essential for human and other lives such as marine and plants. However, water pollutions are a serious issue that needs to be solved. One of the actions that needs to be taken is to monitor the water quality regularly. However, many areas still used manual monitoring due to high cost of automatic monitoring system. Hence, this study aims to develop a low-cost and low-power water pollution monitoring system using a microcontroller and long-range wireless system (LoRa). The system monitors the water pollutions through pH and temperature sensor. Next, the data transmitted to a host PC wirelessly through LoRa communication. The data received will bs stored in a cloud with GUI. Moreover, the system equipped with a PV panel and Lithium-ion battery storage. This will allow the system to be deployed in remote areas with no power sources. The system performance on pollution detection and transmission distance were tested via several experiments. Several substances with different pH values were used simulate polluted water. Meanwhile, the data transmission was evaluated through several distance parameters. The results show the system successfully able to monitor polluted water with high accuracy and capable to transmit long-range data wireless. Hence, the system has efficient power usage through few numbers of sensors alongside LoRa that uses low power for communication.

Authors: Robynson Anak Dondang  , Zuhanis Mansor  , Gandeva Bayu Satrya
Published: July 2022

Flood is a natural disaster caused by the rise of water levels, typically in urban areas. This phenomenon can cause damages to properties such as buildings and landscapes. Moreover, it also can cause death among humans and animals. Malaysia is among the country that has rainfall throughout the years alongside monsoon seasons. Therefore, this country is prone to floods that are not predictable that causes the public to be unprepared to face potential floods. Although the authorities have taken some measures, such as the installation of the monitoring system, it is not efficient, expensive, and difficult to maintain. Hence, this study aims to design a low-cost flood monitoring system comprising a rainfall sensor, temperature sensor, humidity sensor, controller (Arduino), and GSM modem. The system will monitor the rainfall rates alongside temperature and humidity in deciding for the potential occurrence of flood. The data will be sent to a host PC with Graphical User Interface via GSM modem. The developed prototype aims to be installed at a selected location for monitoring and testing.

Published: July 2022

Currently, the indoor plants are watered and fertilized manually every day. However, incorrect watering and fertilizing may result in plants perishing, not flowering, or not thriving. Moreover, users also need knowledge in temperature and humidity to take care of specialized plants and have a longer life. The current lifestyle also limits the ability of the user to maintain their indoor plants. Therefore, this study aims to develop an IoT-based plant monitoring and watering system. This system seeks to water the plants based on schedule and user input automatically. The single, smart pot system comprises controllers and sensors to monitor plant growth and automatic watering and fertilizer. The sensors include temperature, humidity, and soil moisture sensors. The data is transferred through Wi-Fi to a smartphone application where all the data can be viewed. Additionally, the system will have a Graphical User Interface (GUI) that shows the plant's current conditions. The plant status in the GUI includes information such as temperature, humidity, and whether the light is on or not. Information like when the plant will be watered and fertilized is also displayed. Finally, the time when the light will be toggled on or off is shown as well. The data is also used to manage the plant watering and fertilization processes

Constructing a Secure Data Storage System That Supports Multiple Functions by Using Key Aggregation for Data Sharing in Cloud Storage: A Review
Authors: Ismael Othman Atta
Published: July 2022

The old method used for examining data correctness is to recover the entire data from the cloud and then validate data reliability by scrutinizing the correctness of signatures or numeric values of the data as a whole. In modern cryptology, an essential problem to study here is to maintain the greatest benefit of the privacy of given information to perform multiple encryptions. The study shows how a decryption key is made stronger in the sense that it enables several ciphertexts to be decrypted without increasing their size. The statement of the problem lies in the fact that creating an effective public-key encryption system that supports flexible delegation is decipherable by a fixed-size decryption key that could be produced by the holder of the master-secret key. The solution to this problem is by presenting a definite type of public-key encryption known as key-aggregate cryptosystem (KAC). By using this method, users who hold master-secret key could convert a message through a public-key, and an identifier of ciphertext called “class”.  This means that the ciphertexts could be further categorized into various classes. The main objective of this paper is to design a secure data storage system that provides multiple stimulating functions by which the storage system is divided and has no major authority.

The main aim is to prevent bacterial adherence on these surfaces, presenting a valuable strategy for nosocomial infection control. The adherence percentage of both S. aureus and E. coli were significantly decreased, and eradication to below limit of detection was demonstrated for 24 hr, contributing to decreasing biofilm formation.  
Semantic and Stylistic Features of Kant’s Observations on the Feeling of the Beautiful and the Sublime: The Art of    Seeing and Describing an Object
Authors: Babaeva Anastasia V. , Guseva Ludmila V. , Kim Olga M.
Published: July 2022

Immanuel Kant’s Observations on the Feeling of the Beautiful and the Sublime is examined in the context of the emergence of the epistemological practice of scientific observation. By focusing on the genre-stylistic and semantic-structural features of the text the authors demonstrate the mechanisms of observation as well as the methods of describing the results characteristic of mid-eighteenth century science. The authors consider Kant’s treatise to be a hybrid text: on the one hand, it attests to the importance of the natural science paradigm and the degree of its influence on the humanities in the modern period; and, on the other hand, it bears witness to the multi-genre character of philosophical treatises, combining as they do the considered and serious wisdom of philosophy, the precision of scientific terminology and the figurativeness of a work of fiction. Kant is perceived not only as a researcher and philosopher capable of bringing out the essence of the particular and changeable captured in observation, but as a writer with a consummate command of the apparatus for keeping the reader’s attention through linguistic devices and practices of image-creating. The authors demonstrate how the categories of the “beautiful” and “sublime” become a general framework for the description of the moral and mental properties of human nature. The authors show that Kant’s use of “aesthetic” wording in the title of his treatise does not announce that his aim is analysis of artistic perception and practices, but mainly refers to the form of his anthropological study and conceptualisation of scientific knowledge. Kant has transferred the technique of visualisation from natural sciences to the objects of philosophical inquiry, thus contributing to the development in the humanities of representative practices, the scientific method of observation as well as the corresponding epistemic and literary genre.

Various statistical methods were applied in this research: analysis of genetic parameters, Pearson's correlation, genotypic and phenotypic correlations, and Path analysis, with the aim of creating a selection criterion for increasing wheat grain yield. A two-year experimental study was conducted with twenty-seven wheat genotypes, grown on two localities: Rimski Šančevi (Bačka, Vojvodina), on Chernozem soil type; and Kumane (Banat, Vojvodina), on Solonjec soil type. The highest values of phenotypic coefficient of variation (CVp) had the grain weight per plant (17.44% on Chernozem and 13.81% on Solonetz), while the lowest value of CVp had the thousand grain weight (8.12% on Chernozem and 5.47% on Solonetz). On Chernozem, the value of the genotypic coefficient of variation (CVg) ranged from 1.51%, in the number of grains per spike, to 9.17% in the spike length, while on Solonetz, grain weight per plant had the lowest value of CVg (0.36%) and plant height the highest one (11.15%). At both localities, grain yield was in highly significant and positive correlations with all analyzed traits, except with plant height and spike length. In favorable environmental conditions (Chernozem), Path analysis revealed that grain yield directly depends on grain weight per spike (0.317**), number of grains per spike (0.232**) and spike weight (0.209**), and other analyzed traits have a positive indirect effect on grain yield over mentioned traits. Under salinity stress conditions, the grain weight per plant had the highest direct effect on grain yield (0.891**), which makes this trait a good selection criterion in breeding for salinity stress tolerance.
Phytotherapy of acute upper respiratory tract infections in children

Published: July 2022

Acute upper respiratory tract infections (URIs) are the most common infections in the population, especially in children. URIs are mostly of viral origin and tend to resolve spontaneously in approximately one week. Bacterial URIs are less common, and come mostly as superinfections of acute viral diseases. The therapy is symptomatic and aimed at alleviating cough, maintaining the patency of airways and preventing disease progression. If there are no reasons to see a doctor, parents should be advised to apply general measures and give herbal medicinal products to their children, in an attempt to relieve cough, sore throat and nasal symptoms. In productive cough, herbal expectorants, such as, for example, Hederae helicis folium extracts, are used to facilitate the elimination of mucus. On the other hand, demulcents (Althaeae radix, Plantaginis lanceolatae folium) alleviate dry cough by reducing local irritation. Honey also significantly reduces the frequency and severity of acute cough episodes. Extracts of Sisymbrii officinalis herba and Pelargonii radix are useful for the alleviation of nasal symptoms and sore throat. If the application of the proposed herbal products does not resolve the symptoms within a week, advice of a medical doctor should be sought.
Treatment of the most common respiratory infections in children

Published: July 2022

Acute respiratory infections are the most common group of infective diseases in the pediatric population. Although the improvement of health care and vaccination program has led to a significant reduction in the incidence of certain respiratory infections, the combination of a high prevalence in vulnerable pediatric categories and uncritical prescription of antibiotics, due to the inability to adequately distinguish between viruses and bacterial etiology, still represents a significant challenge for the public health system. In order to promote rational antibiotic therapy with an overall improvement of both diagnostic and therapeutic principles, acute respiratory diseases have been the subject of consideration in numerous publications and national guidelines. Nonspecific clinical manifestations with pathogen heterogeneity and both anatomical and physiological characteristics of the child's respiratory system during growth and development have created the need for individualized therapy. Since the guidelines emphasize the undoubtful and crucial benefits of symptomatic therapy (e.g. analgesics in acute otitis media, supplemental oxygen in lower respiratory tract infections with hypoxemia), the use of antibiotics and corticosteroids is indicated in selected cases with a severe clinical picture. The choice of antibiotic depends on the clinical condition, presumed causative agent, and local epidemiologic circumstances. Respiratory support (oxygen therapy and/or artificial ventilation) is reserved for inpatient treatment of cases with a particularly severe clinical picture and associated complications.
Medications and non-pharmacological measures to alleviate the symptoms of respiratory tract infections in the pediatric population

In the pediatric population, acute respiratory tract infections (RTIs) are the most common reason for seeking professional help from a physician or a pharmacist. Alleviation of symptoms is the only therapeutic measure in viral RTIs and is an adjunct to antibiotic therapy in bacterial RTIs. This article discusses pharmacologic and nonpharmacologic options for treating nasal congestion, cough, fever and sore throat in RTIs and clinical evidence on their efficacy and safety in the pediatric population. In general, clinical studies conducted in children for most of these drug groups are few or nonexistent, making it difficult to create evidence-based recommendations. Nasal decongestants, cough suppressants, mucolytics, expectorants, antipyretics/analgesics and sore throat local preparations are available in suitable pharmaceutical forms and strengths for the certain age. As many of them are over-the-counter (OTC) preparations, it is necessary to strictly take into account the age of the child in whom they may be used and dose properly. Multicomponent preparations carry the risk of taking unnecessary medications and of their side effects. The use of multiple OTC medicines is associated with the risk of an overdose of a component that may be present in different preparations. Appropriate non-pharmacological measures (e.g. oral hydration, nasal saline application or irrigation, honey) may be helpful and should be used whenever possible due to their safety.

In order to find out whether the guests like to pair food and wine, a research was conducted on the basis of experiences on harmonization of food and wine in Belgrade. The aim of the research was to determine whether sociodemographic characteristics influence the factors of gastro-oenological offer. In order to contribute to the development of catering facilities and their offerings, one of the main research factors was the factor of future intention to revisit and verbally promote the restaurant. A structured field survey questionnaire was conducted on a sample of 226 guests of catering facilities on the territory of Belgrade. The generated data was processed by the SPSS software package, including MANOVA analyzes and descriptive statistics. The obtained results show that sociodemographic characteristics influence the selection of gastro-oenological offer and experience related to the harmonization of food and wine and future intentions.

The primary goal of the paper was to analyze the fish market of Bosnia and Herzegovina (B&H). The paper presents the level of self-sufficiency and import dependence of fish for the period 2014-2020. The source of data was the data of the B&H Agency for Statistics and Indirect Taxation Authority of B&H. The following methods were applied: descriptive statistics, trend data and balance sheet method. On average, 3.161 tons of trout were produced in B&H per year, 82% of total fish production. Carp were produced 510 tons per year. Other freshwater fish are becoming less and less attractive for production. B&H's fish self-sufficiency is low (54%) and the average rate of import dependence is about 76%. The consumption of fish per capita is 2 kilograms. It is necessary to improve the education of the population throughout B&H about the importance of fish nutrition and the health aspects of its consumption.

The paper aims to present the movement of the Belgrade Stock Exchange index from the beginning of the epidemic in the Republic of Serbia until the middle of 2021, as well as a review of the movement of the most important indices in the world. The global crisis, caused by the spread of the virus, but also by rigorous measures introduced by the entities authorized by the Government, resulted in a decline in general economic activity, economic slowdown in the capital market and, consequently, a decline in stock indices in the world and in our country. The results of the research indicate that, in general, the indices show drastic declines as early as the beginning of 2020, and although they ended the year with a positive trend, most of them have not yet recovered. The indices of the Belgrade Stock Exchange, already weak, despite a certain degree of recovery during the second half of 2020, had a negative trend compared to the year before. It is completely unknown how long the pandemic and the crisis will last, so it is difficult to predict the further course of events, but it is certain that the consequences will be felt for a longer period of time in economic flows, primarily through increased inflation and further deterioration of public finances.
