Authors: Sabdaningsih Anindita , Lunggani Arina Tri
Published: June 2022

Bledug Kuwu is an area that has a fairly high salt content, this is caused by sea water trapped in the sedimentation process around the 18th century. Microorganisms that are able to live in extreme areas tend to have typical metabolic activities and can be utilized in industry. The purpose of this study was to characterize microbiologically, bacteria isolated from Bledug Kuwu, Kradenan District, Grobogan Regency, Central Java. The method used in this study was isolation on LB + NaCl media with NaCl levels of 10%, 12.5% and 15%. Characterization was done by Gram staining and motility test. The results obtained in samples from 3 sources, namely teak water, salt water and mud water, obtained 8 pure isolates. The seven isolates have the ability to grow optimally at 10% NaCl concentration so that these bacteria can be classified as moderate halophilic bacteria with the majority of species being coccus, Gram positive, and non motile.

This study aims to determine the effect of organic growing media composition of husk charcoal and cow dung on the growth and survival of red chili (Capsicum annum L.) and cayenne pepper (Capsicum frutescens L.). The research was conducted in November 2019 – February 2020 in Faennake Village, North Bikomi District, TTU Regency. The method used in this study is an experimental method with a two-factor randomized block design with five treatments and four replications. The first factor is a large red chili plant. The second factor is cayenne pepper plants with different planting media treatments. The parameters studied were plant height, number of leaves, number of fruit, number of productive branches and plant survival of red chili and cayenne pepper. Data were analyzed through ANOVA with an error rate of 0.5% and to determine the difference between treatments using Duncan's multiple range test with a significance level of 5%. The results showed that the survival of red chili and cayenne pepper in each treatment was good because each planting medium was able to meet the needs of these plants. As for the growth in the treatment of 50% soil, 25% husk charcoal, 25% cow dung, it showed a good effect where in red chili plants the plant height at 45 DAP was 59.5 cm. And for cayenne pepper plants at 45 DAP, which is 50.75 cm. From the observations, it can be concluded that the composition of the growing media 50% soil plus 25% husk charcoal and 25% cow manure was able to increase the growth and yield of Capsicum annum L. and Capsicum frutescens L. plants.

The Semarang City is a metropolitan city with such rapid development, so that it also affects several animals, one of which is birds. One species of bird that can be found in various habitats is the Genus Lonchura. This study aims to examine the abundance and population distribution, feed preferences, and the availability of food plants for munia in urban, suburban, rural habitats in Semarang City. Data were collected using the transect method, Visual Encounter Survey (VES), and quadratic. Analysis of the data used are abundance index, diversity index, equity index, Morisita index, Kruskall-Wallis test, and Chi-Square Test/ Goodness of Fit. Three species of Lonchura, namely Scaly-breasted munia (Lonchura punctulata), White-headed munia (Lonchura maja), and Javan munia (Lonchura leucogastroides), are found in urban, suburban and rural habitats. The Genus Lonchura in urban and rural habitats is dominant, while the distribution of the bondol bird population based on the Morisita Index is clumped. The munias also did not show any food preference for the types of forage plants.
Magnetic Susceptibility of Volcanic Rocks from Pahae Julu Region, North Sumatera Province
Authors: Siregar Nurmala Dewi , Rifai Hamdi , Syafriani Syafriani , Fauzi Ahmad , Mufit Fatni
Published: June 2022

Pahae Julu is a sub-district located in North Tapanuli Regency, North Sumatra. This area is often found with volcanic material from the eruption of Mount Toba (Youngest Toba Tuff). The Youngest Toba Tuff eruption occurred ~74,000 years ago with a volume of 2,800 km3. When there is an eruption, the lava on the earth's surface undergoes a relatively fast freezing process to form volcanic igneous rock. These rocks contain various minerals, one of which is magnetic minerals that can be used as a track record of volcanic processes from Mount Toba. However, no document records the magnetic susceptibility value of the Youngest Toba Tuff volcanic rock in the Pahae Julu area. This research aimsbfor knowing the abundance of magnetic minerals by the low-field magnetic susceptibility. To achieve this goal, the rock magnetism method is used. This way is very effective, cheap, sensitive, and non-destructive. Magnetic susceptibility measurements are done using the Bartington Magnetic Susceptibility Meter MS2B sensor. Rock samples analyzed are pumice which is the result of the Youngest Toba Tuff eruption. The results showed that the magnetic susceptibility value obtained for the sample was between 85.0 x 10-8m3/kg – 183.1 x 10-8m3/kg with an average of 119.78 x 10-8m3/kg. Based on this value, it is assumed that the magnetic mineral properties are Antiferromagnetic. The average value of χ fd% obtained is 0.95%, indicating that the Youngest Toba Tuff volcanic rock in the Pahae Julu area has almost no Superparamagnetic grains.
Time: A Historical Sociology Perspective
Authors: Brown Lucy
Published: June 2022

This review concerns Jiří Šubrt’s latest book The Sociology of Time: A Critical Overview (2021) and examines the text within the framework of sociological and historical sociological thought. Šubrt’s book attempts the ambitious task of summarising the ‘labyrinth of questions and answers’ [Šubrt 2021:1] surrounding the topic of time within the field of sociology. In doing so, the author provides a detailed exploration of various theoretical approaches to time which are drawn from his extensive knowledge of the historiography of sociological thought. Owing to his own theoretical background in processual and historical sociology, one of the core themes of The Sociology of Time is the concept of temporalized society as a distinct theoretical approach to the sociology of time. As a historical sociologist primarily focused on theoretical concepts, Šubrt presents us with an analysis of the attempts to understand time within theoretical paradigms. By offering a variety of sociological approaches and linking their various developments across the 20th century (and sometimes before), Šubrt is guiding the reading towards the conclusion that a sociology which lacks a temporalized grounding is theoretically insufficient.
American National Identity and Portrayal of the Russian Empire in The New York Times in the Late Nineteenth Century
Authors: Behrends Haylee
Published: June 2022

This article seeks to identify how U.S. media in the late nineteenth century sought to portray the Russian Empire in the late nineteenth century. The primary focus is on the “newspaper of record” The New York Times, which reflected to a certain degree the attitudes of the American people, but more so reflected the stance of the “powers that be” in the United States – the government and the business class. The main goal of this article is not to make conjecture about what nineteenth century Americans believed, or to state that there was an agenda against the Russian Empire. Rather, the goal of this article is to demonstrate that American attitudes reflected in U.S. media towards the Russian Empire were shaped by the media, and that the portrayal of the Russian Empire was not entirely positive or negative, although followed a negative trend over time for various reasons. The reasons for negative portrayal of the Russian Empire in The New York Times were arguably connected to various tsars in power and their personalities and a shift in world alliances bringing the United States closer to Great Britain. The portrayal of the Russian Empire in U.S. media as well as the reasons for its eventual negative stance, led Russia to be a suitable “other” in American national identity formation as the twentieth century unfolded.
Soviet Secularisation: the Experience of the Old Believers in Eastern Latvia
Authors: Grizāne Maija
Published: June 2022

The article provides the first overview on Soviet secularisation and the response of priest-less Old Believers in Latvia. Unlike Russia, Latvian Old Believers had the experience of longterm living in democracy before they were incorporated in the Soviet system. This fact played a crucial role in the strategies of preserving religiosity under atheism. The studied oral life-stories demonstrate that the majority of Old Believers chose living a double life of a trustworthy Soviet citizen in public and a devoted follower of the faith in private. Overcoming restrictions in social career, education and personal realisation allowed passing the religious traditions to the further generations. At the same time, the lack of systematic religious practice and all-round social pressure contributed to the diminution of the role of religion in people’s life and their worldview.
Naše nynější krize: Pokus o po třetí pro Jóhanna Pálla Árnasona
Authors: Havelka Miloš
Published: June 2022

Taking Lovejoy’s history of ideas perspective, the study compares two central texts of Czech political philosophy: Our currently Crisis of T.G. Masaryk (1895) and the essay of the same name by Karel Kosík (1968) and shows two forms of thematization of the crisis of modernity in a particular constellation on national life. The paper points out their thematic and argumentative analogies and analyses them against the background of the more general themes of the Czech political culture: spontaneous egalitarianism, distrust of politician, the role of writers, narrow conceptions of party politics, opinion polarisation of public. The paper then examines the texts as historically concretized answers to the changing social structure of the Czech national society. Masaryk’s text was written at the height of (what M. Hroch calls) the “third phase” of the emancipation of the “small nation”. The second text came at the time of the unfinished and unsuccessful stabilization of the social structure of Czechoslovak society after the 1948 communist coup, culminating in attempts at political reform in 1968. The authors are convinced of the “crisis of the modern man”, of the emptiness of the ideas of their world and the loosening of its values, the alienation of the political system and the non-principled pragmatism of problem-solving. A strong common motive is the critique of politics as the dominant and “all-wrenching” sphere of social and cultural life. While T. G. Masaryk saw a solution in updating the supra-individual and trans-national political and spiritual values of communal life, Karel Kosík believed that redress could be based on a return to the “pre-Stalinist” idea of proletariat as a “subject of history”.
Branná výchova jako nástroj sociální kontroly
Authors: Kyselák Jan , Rožňák Petr
Published: June 2022

Looking at the security environment and the genesis of military education in Czechoslovakia and the successor states, they point to the harmfulness of the ideologisation of this education, underestimation, insufficient funding and the absence of theoretical teaching and practical training in schools of all levels. The basic mechanism of functioning of the security environment not only in the Czech Republic is a comprehensive connection of military education with the life of society, which is influenced by internal and external vertical and horizontal relationships, where there are a number of friction areas and significant security risks. The main players in security on the threshold of the new decade of the 21st century are facing new challenges and perspectives.
Caravanning in Socialist Czechoslovakia
Authors: Štemberk Jan
Published: June 2022

This study is devoted to the rise of caravanning in Czechoslovakia with emphasis on the period from 1948 to 1989. After introducing Czechoslovak caravanning in a broader context, it focuses on the production of caravans and their availability on the market. It then goes on to examine the legislative rules in force governing the production and operation of caravans. The focus is on the period of the 70s and 80s, when the accelerated development of caravanning in Czechoslovakia was restricted by the limited availability of caravans on the market, most of which had to be built individually on a DIY basis. The final part also takes a brief look at the development of motorhomes.
GIS-based landslide susceptibility mapping using frequency ratio and index of entropy models for She County of Anhui Province, China
Authors: Liu Yu , Yuan Anying , Bai Zhigang , Zhu Jingzhong
Published: June 2022

Landslides caused countless economic and casualty losses in China, especially in mountainous and hilly areas. Landslide susceptibility mapping is an important approach and tool for landslide disaster prevention and control. This study presents a landslide susceptibility assessment using frequency ratio (FR) and index of entropy (IOE) models within a geographical information system for She County in the mountainous region of South Anhui, China. First, the landslide locations were ascertained in the study area using historical landslide records, aerial photographs, and multiple field surveys. In all, 502 landslides were identified and randomly divided into two groups as training (70%) and validation (30%) datasets. Additionally, the landslide-influencing factors, including slope angle, slope aspect, curvature, landform, lithology, distance to faults, distance to roads, distance to rivers, rainfall, and normalized difference vegetation index, were selected and their relative importance and weights were determined by FR and IOE models. The results show that the very high and high susceptibility classes cover nearly 50% of the study area. Finally, the comprehensive performance of the two models was validated and compared using receiver operating characteristic curves. The results demonstrated that the IOE model with the area under the curve (AUC) of 0.802, which is slightly better in prediction than the FR model (AUC = 0.786). The interpretation of the susceptibility map indicated that landform, slope degree, and distance to rivers plays a major role in landslide occurrence and distribution. The research results can be used for preliminary land use planning and hazard mitigation purposes.
Collusion, Shading, and Optimal Organization Design
Authors: Suzuki Yutaka
Published: June 2022

We introduce a behavioral contract theory idea, “shading” (Hart and Moore (2008). “Contracts as Reference Points.” Quarterly Journal of Economics 123 (1): 1–48)) as a component of ex-post haggling (addressed by Coase (1937. “The Nature of the Firm.” Economica 4 (16): 386–405) and Williamson (1975. Markets and Hierarchies: Analysis and Antitrust Implications. New York: Free Press)) into the collusion model à la Tirole (1986. “Hierarchies and Bureaucracies: On the Role of Collusion in Organizations.” Journal of Law, Economics, and Organization 2: 181–214, 1992. “Collusion and the Theory of Organizations.” In Advances in Economic Theory: The Sixth World Congress, edited by J. J. Laffont. Cambridge: Cambridge University Press), thereby constructing a new model of hierarchical organization. By integrating the two ideas, i.e. collusion and shading, we enrich the existing collusion model, thereby obtaining a new result for Collusion-proof versus Equilibrium Collusion. The basic idea is that the increase in shading pressure strengthens the incentive for collusion, thereby making it difficult to implement collusion-proof incentive schemes, which leads to the Equilibrium Collusion. In addition, we also provide a micro-foundation for ex-post haggling costs, where we view rent-seeking associated with collusive behavior and ex-post haggling generated from aggrievement and shading as the two sources of the costs. This model is used to examine the optimal organizational design problem as an optimal response to the trade-off between gross total surplus and ex-post haggling costs, and to take a step further the idea of efficient organization design (Milgrom (1988. “Employment Contracts, Influence Activities and Efficient Organization Design.” Journal of Political Economy 96: 42–60)). We believe that our model could help provide a deep understanding of resource allocation and decision processes in hierarchical organizations.

Authors: AL-Mandalawi Sanaa , Ismail Ava , Mustaffa Shatha
Published: June 2022

Background and objective: Metabolic syndrome is a potent risk factor for cardiovascu-lar diseases (CVDs), has not been adequately explored in Erbil individuals and its relation to leptin hormone. The present study aim to evaluate such a relationship between serum leptin and metabolic syndrome in Erbil individuals. Methods: Samples collection were carried out in Razgary teaching hospital, 45 cases with metabolic syndrome and 30 healthy control subjects, anthropometric variables measure-ments (blood pressure, body weight, body height, body mass index) and biochemical tests: fasting, serum glucose, serum triglycerides, high-density lipoprotein cholesterol and serum leptin were obtained from the study samples. Results: Serum leptin levels were significantly higher in females in comparison to the males in metabolic syndromes group (with median 53.6 Vs 23.8 ng/dl with P value < 0.05) with also present statistical significant difference in leptin between metabolic syndrome group and control group in both males and females. No important association between se-rum leptin and each of selected criteria of metabolic syndrome. The observed case-control difference in serum leptin is mainly attributed to gender and body mass index (BMI) differ-ences and not a function of metabolic syndrome itself. Conclusion: Among subjects with metabolic syndrome, only age , gender and body mass index were important in determining the magnitude of serum leptin among cases groups.

Published: June 2022

Background and objective: Induction of labor is deemed successful when it initiates uterine contractions, progressively dilates and effaces the cervix, and leading to the normal vaginal birth of the baby with no maternal or fetal complications . Because the success of induction is related to cervical ripening, artificial cervical ripening before labor induction is used when the cervix is unfavorable to reduce the associated risk of cesarean delivery. The objective is to test the efficacy and safety of Isosorbide mononitrate for cervical ripening before the induction of labor at term, from. Methods: A randomized clinical trial was conducted in maternity hospital in Sulaimani, from the 1st of January 2008 to the 1st of July 2008. Forty six pregnant women with gestational age of (37- 42) weeks, singleton, viable, low risk pregnancy and cephalic presentation with Bishop score of less than 6 were selected for induction of labor for various causes. Forty eight hours before induction, 40 mg IMN (2 tablets of 20 mg) were inserted vaginally up to 3 doses 16 hours apart. Results: It was found that the mean ± SD Bishop score before IMN administration was (1.95 ± 1.5), while after IMN was (6.65± 3.06) P-value = 0.0001. Sixteen cases (35.6%) went to active labor. The mean ± SD time of admission in labor room was (5.06 ± 3.8) hours.43 cases (93.5%) needed oxytocin for their inductions & eighteen cases (39.1%) were delivered by C/S. There was no significant change in FHR before and after IMN and all women delivered active babies with normal Apgar score. The main side effect was headache which was experienced by 31cases (63.4%). Conclusion: IMN is an effective and safe agent for cervical ripening which can be used as an outpatient basis.

Published: June 2022

Iatrogenic intra operative acute coronary artery obstruction is a rare and potentially fatal complication of valve surgery [1]. Sudden coronary spasm, embolization of calcium plaque, and surgical factors can induce acute coronary obstruction after AVR [2]. Initially described in 1967, following aortic valve surgery, it is now recognized that patients who develop myocardial ischemia postoperatively following valve surgery, should be investigated deeply to exclude this rare phenomenon as the cause of myocardial dysfunction [3]. Although most reports highlight the potential for coronary artery stenosis in the months following valve surgery there are few documented cases of intraoperative coronary embolism causing circulatory collapse and requiring prompt treatment [5]. After Ethical Committee approval and after written consent taken from the patient family for publication, we present a case of acute intra operative left main coronary artery obstruction after Aortic Valve Replacement (AVR) and its immediate management.

Background: Virtual Bronchoscopy is a recent method that permits visualization and evaluationdown to the fourth order branches. In comparison with CB, VB can analyze extra luminal compressions and also evaluate areas beyond even high-grade stenosis, even more mapping the route for scoping by FOB or RB which may be troublesome or distressing to the patient. Methods: This randomized study included five hundred patients with different lesions of thethorax. All of them were admitted to Benha university hospitals from October 2012 to October 2019. All cases were examined with either FOB or RB then reviewed by radiologists and thoracic surgeons. These results were compared with each other’s. Results: FOB and RB time has been decreased by VB which guide the thoracic surgeon evenmore facilitate transbronchial needle sampling for the extraluminal pathology. Conclusion: VB is currently used in clinical practice and seems valuable to review its potentialclinical diagnostic indications. Both VB and CB might be considered as complementary modalities for confirmation of this diagnosis. Keywords: CT=computed tomography, FOB=fiber-optic bronchoscopy, CB=conventionalbronchoscopy, RB=rigid bronchoscopy, VB=virtual bronchoscopy.

Published: June 2022

The Tribological behavior of Polystyrene Crystal disc sliding against a steel 100Cr6 ball with a radius of 5mm over a range of loads (1-5N) and speeds (12.5-63mm/s) was investigated using a ball-on-disc tribometer under unlubricated conditions. All the specimens were used as obtained from injection molding. For this purpose, we monitored the evolution of the friction coefficient and the wear rate as a function of sliding speed and normal load applied. The worn surfaces were examined by Scanning Electron (SEM) and optical microscope. Several wear mechanisms were observed: plastic deformation, abrasion in the track, and adhesion at the edge of the track. The mechanisms were found to depend on speed and load. The wear rate is of the order of 10-2mm3/N.M, which may explain that the wear is of a severe type.

Published: June 2022

The Undergraduate Diploma in Horticultural and Floricultural Production was created in 2018 at the National University of La Plata (UNLP) to generate a training space for horticultural and floricultural producers in the region. Thus was born an initiative that seeks to incorporate into the university educational system those people who, without having a secondary degree, are trained according to their needs and interests. With the premise of approaching the teaching-learning process from a Freirian perspective and counting on a teaching body integrated almost entirely by teachers from the Faculty of Agricultural and Forestry Sciences (UNLP), the first cohort was developed in 2019. his first experience was carried out through a series of meetings to involve the recipients to optimize the production system, discuss practices and management for horticultural and floricultural production and discuss some practices of the dominant model. The result has been acceptable, although reflection on the experience generates questions and answers about the objectives, methodology, actors (mainly producers and teachers), and types of intervention in a productive and socioeconomic context like the current one.

Del arrabal a la estepa: la ciudad, la modernidad y la naturaleza en la poesía y la narrativa del Grupo del 27
Authors: Ramírez Guerrero Ángela , Rojas Arias Gabriela
Published: June 2022

El presente artículo trata sobre la exaltación de la ciudad y la modernidad y el regreso a la naturaleza en una selección de escritores del Grupo del 27. Los objetivos de este trabajo incluyen el análisis de los cada uno de los textos por separado y, posteriormente, hacer una comparación entre los autores con la temática de la ciudad y la modernidad y los autores que exaltan la naturaleza. El corpus seleccionado es un poema y en relato de cada escritor: Concha Méndez, Lucía Sánchez, Benjamín Jarnés, Cristina de Arteaga, Margarita Ferreras, Josefina Romo y Max Aub. Los hallazgos sugieren fuertes contrastes entre los escritores que retoman la naturaleza en su producción literaria, pero no así en los autores que trabajan la temática de la ciudad y la modernidad.

El presente artículo plantea la necesidad de que las instituciones educativas se comprometan con la diversidad por medio de la adopción de una perspectiva de diversidad sexual y de género, por medio de la propuesta de un modelo de implementación. Como conclusión, este modelo permite bosquejar una hoja de ruta para la inclusión, brindando una herramienta útil para el desarrollo de políticas y acciones enfocadas en la diversidad y el respeto e inclusión de personas del colectivo LGBTIQA+ que integran la comunidad educativa.
Contribution of Public Libraries to Economic Development: Panel Data Analysis for TR2 and TRC Regions in Turkey
Authors: Azazi Hasan
Published: June 2022

When considered as a form of power from the past to the present, it is seen that the phenomena of land and capital, respectively, have affected the decision-making mechanism in the world. It can be stated that this evolution of management has continued with knowledge. Today, knowledge is power, and this power rules the economic structure of the world. Management is not a phenomenon that can be considered outside of economic relations. In this case, knowledge and economic development actually move together at much higher rates than anticipated. Today, although these two phenomena are observed on very advanced technological wars, the basis of the issue is based on the most local information centers – public libraries. Studies on public libraries have focused on librarianship as a field article. In order to add a more macro character to the field, the relationship between public libraries and economic growth, which is a macroeconomic variable, was analyzed in this study.
The relationship between knowledge and economic growth and development was investigated in this study. While examining this relationship, selected level regional groups in Turkey were used. Two different polar regions of Turkey, which are geographically and culturally different, were selected, and public libraries were discussed at the point of representing knowledge. In this case, the role of public libraries on economic development was explained.
The annual data for the period between [2015-2020] were used in the study. The data on the number of users, registered members, loan materials, library numbers, and book numbers related to public libraries were used to represent the independent variable of the study. The data covered all provinces included in the TR2 (Çanakkale, Balıkesir, Tekirdağ, Edirne, Kırklareli) and TRC (Gaziantep, Kilis, Adıyaman, Şanlıurfa, Diyarbakır, Mardin, Batman, Şırnak, Siirt) level regions. Per capita income, export figures, and the number of illiterate and unemployed people belonging to the provinces included in the TR2 and TRC regions were used to represent the dependent variable of the study.
In the study, three different models were established using the Panel Data Analysis method. Two of these established models were established for the TR2 region and one for the TRC region. As a result of these established models for TR2, it was seen that the Registered Member and User Number variables in the TR2 Level Region had a positive effect on economic development. In the model established for the TRC region, it was observed that the Registered Member and Book Number variables had a positive effect on economic development. In the light of the findings obtained from the study, it is necessary to include more supportive local policies that will increase the direct and indirect effects of public libraries on individuals and the economy.

Одним із найважливіших завдань в досяжному майбутньому є ще більше розвинення технологій, що дозволяють вилучати воду з повітря, причому безпосередньо на місці, де вона необхідна. Найбільші перспективи мають методи, пов'язані з роботою автономних генераторів штучного холоду, які гарантовано забезпечують температуру охолодження повітря нижче точки роси – установок отримання води з атмосферного повітря на базі абсорбційних водоаміачних термотрансформаторів (АВТТ), що працюють від джерела низькопотенційного тепла – сонячної енергії. З урахуванням аналізу відомих технічних рішень запропоновано схеми систем життєзабезпечення житлового будинку, на прикладі кліматичних умов Одеської області, з використанням традиційних та відновлюваних джерел енергії. Запропонована базова схема, яка є удосконаленою технічною пропозицією універсальної системи опалення, охолодження (кондиціювання) та отримання води з атмосферного повітря на базі традиційних та відновлюваних джерел енергії (сонячних колекторів). Для рішення задач отримання холоду була запропонована оригінальна конструкція АВТТ з бустер-компресором після генератора, яка захищена патентними документами України. Включення в схему бустер-компресора дозволяє суттєво розширити робочі характеристики у частині рівня температур гріючого джерела. Так, наприклад, він необхідний у схемах із сонячними колекторами з водою у якості теплоносія, де температура не перевищує 100 °С. Доведено, що для умов роботи випарника при температурі 5 °С спостерігається зниження електричної потужності в системах АВТТ з бустер-компресором, порівняно з парокомпресорними аналогами, у 3,3 рази при експлуатації в помірному кліматі і у 2,4 рази – у тропічному кліматі. У результаті розрахунку було визначено в практичному діапазоні параметрів експлуатації систем з сонячними колекторами енергетично ефективний режим для бустер-компресора. Для систем при експлуатації в помірному кліматі це: тиск кипіння в генераторі 1,0 МПа і температура 80 °С. Запропонована також автономна холодильна установка на базі безнасосного абсорбційного холодильного агрегату. Виконано аналіз кліматичних умов одеського регіону. До уваги взяли найпівнічніше місто – Подольськ, місто у середині регіону – Одеса, та місто на півдні –Ізмаїл. При проведенні аналізу середньомісячної температури було виявлено найліпші місяці для утворення конденсату: квітень – жовтень. Було виявлено, що місто Ізмаїл є найвигіднішим для утворення конденсату, та отримання води з атмосферного повітря, у зв’язку з південними координатами регіону

The research aimed the study of an invasive species that has recently appeared in our country, Corythucha ciliata Say (plane tiger or lacy plane bedbug) (Hemiptera, Tingidae). Knowing this pest is very important in order to control it, in order to keep the appearance of the parks pleasant and clean. The insect is an aggressive pest of plane trees (Platanus spp.), which harms their leaves, leading to premature defoliation. The aims of this research were: identifying and monitoring of Corythucha ciliata Say populations; observations on the host plants in the analyzed space; tracking the biological cycle of the species Corythucha ciliata Say and the extent of pest. Following research conducted in 2020-2021, the invasive species Corythucha ciliata Say, was identified in 4 locations in Transylvania, on two species of plane trees, Platanus occidentalis Linné and Platanus x acerifolia Willdenow. In the ecological conditions of Cluj-Napoca (Cluj County), the numerical density of the pest on the plane leaves was of maximum 30 adults/leaf and 63 larvae/leaf. Concerning the biological cycle, it was found that, in the temperate-continental climate of Cluj-Napoca, the species has 2 generations per year.

Ninety, one-day-old Cobb chicks were randomly divided into 3 groups, each with 3 replicates. A control group was fed a standard diet, whereas the other two treatment groups received a diet with 0.2 or 0.3 mL thyme essential oil (TEO) per kg of the diet for 21 days. The 0.3 group had more meat protein (P ≤ 0.048) than the control group, while the other meat constituents have not changed. Meat sensory parameters (external aspect, odour, colour, and elasticity) declined (P < 0.001), while meat quality parameters (pH, total volatile nitrogen TVN, thiobarbituric acid number TBA, peroxide value PV, and free fatty acids FFA) increased (P < 0.001), through storage of the groups. In TEO groups, improved (P < 0.001) meat overall scores, external aspect and muscular elasticity was observed compared to control. Quality parameters were improved (P < 0.001) including pH, TVN, TBA, PV, and FFA, compared to control during storage. TEO had no effect on heavy metal concentrations while reducing bacterial contamination in meat. TEO 0.2 samples were positive for Salmonella Kentuckey and Staphylococcus aureus, while TEO 0.3 group were free from pathogenic bacteria. Thyme essential oil can enhance quality, and safety of the chilled broiler’s breast meat.

The fact that more and more people are suffering from obesity and that this condition is more and more common among children is an alarm signal and some measures must be taken in this direction. Nowadays, the most incriminating factor responsible for the development of childhood obesity is the excessive consumption of fast food, sweets and juices, as at the market there is a wide range and easily accessible. This study aims to evaluate the association between frequent consumption of fast food and other lifestyle factors with the presence of obesity and overweight in children of different ages in Romania. Applying a questionnaire with 31 questions we collected data from 328 people, 170 boys and 158 girls, residing in Romania.  The analysis of the data collected showed a higher number of overweight children, compared to the number of mothers who consider that their children are overweight, for this we identified the factors with potential obesity and we looked for the associations between the lifestyle and obesity. The higher prevalence of fast food consumption and sedentary activities among overweight and obese children, highlighted in this study, further confirms the need to promote health through education for healthy eating and lifestyle behavior.
