"Wireless power transfer (WPT) is a disruptive technology because it gives up the technology of wire transmission, the only one used in electrical and electronic engineering so far. Although made known since the end of the 19th century through the inventions of Nikola Tesla, WPT became applicable in practice only in the 80s of the 20th century with the progress of power - and micro-electronics. The field is now being studied and applied worldwide for transferred power from a few W up to hundreds of kW, as part of electric mobility and beyond. The fact that numerous researches and applications of the WPT have already been carried out in Romania led to the need for a better collaboration and knowledge which resulted in the creation of the national network of interests - WPT Romanian Network (WPT Rom Net) - presented in this paper.

Advanced wastewater treatment targeting water reuse is currently an important research topic and the heterogeneous photocatalysis processes represent potential candidates. Most of the photocatalysts are aqueously stable metal oxides as TiO2 or ZnO; however, their use is limited due to the processes costs as these oxides are wide bandgap semiconductors that are activated only by UV radiation. Many alternatives are investigated to develop VIS- or solar-active photocatalysts among which most effective proved to be the diode type composites that associate the n-type semiconductor (TiO2) with a p-type semiconductor with lower band gap as CZTS or CIS. The challenges raised in developing thin films photocatalysts of diode type are discussed considering the advanced treatment under VIS and simulated solar radiation of a wastewater polluted with methylene blue (standard pollutant). Further on, new composites of TiO2 – Graphene oxide are presented considering the same application
Theory and practice of asymmetrical longitudinal rolling

Published: June 2023

"In the national and international literature of the rolling theory, it is usually resented the plastic distortion between cylinders with equal diameter, meaning the symmetrical rolling, although this process represents only an abstract opposed to the normal conditions, because there exists a difference between the working diameters of the cylinders, and sometimes right after construction the rolling mill is equipped with cylinders of different diameters. It is worth mentioning that for a series of aspects like: the distribution of the unitary pressure on the contact surfaces, the reduction between the cylinders, the bending of the bar exiting from among the cylinders and many others, there are contradictory opinions which are explained through the difficulties that the experimental study of these phenomena imposes, but also because of the different factors which influence or modify the volumetric pressure scheme of the metal material at rolling. For the research of these difficult phenomena the author of the paper conceives an original appliance which allows experiments in order to reach conclusions for the rolling theory among equal diameter cylinders, but also for the industrial practice."

Environmental pollution by anthropogenic activities has become a global concern as the release of organic and inorganic pollutants into the atmosphere is responsible for important health problems among the population. The rare-earth metals processing sector has raised particular problems due to the bioaccumulation potential of these metals in the food chain. Urban trees are able to retain pollutants from the environment and can be used as bioindicators also for the rare-earth metal pollution. This paper aimed to assess the bioaccumulation of some rare-earth metals, besides other metals and non-metals, in the foliar part of six urban tree species (Populus nigra L., Populus tremula L., Populus x canadensis Moench, Betula pendula Roth, Aesculus hippocastanum L. and Fraxinus excelsior L.) sampled from different areas of the municipality of Bucharest. Laboratory experiments have shown that all tree species used in the study are able to retain rare-earth metals, but the bioaccumulation capacity is species-specific.

Published: June 2023

"A circular disc is used to demonstrate the application of the pivoted QLP decomposition to the analysis of the frequency response data for a structure possessing double modes. Frequency Response Functions (FRFs) are generated for excitation and response points on the disc rim. Plots of L-values and Q-response functions obtained by the QLP decomposition with column pivoting are used to determine the system order, damped natural frequencies and modal damping ratios, as well as mode shapes. The performance of the LMIF, QMIF and QCoMIF mode indicator functions is assessed in the presence of degenerate modes. Enhanced FRFs based on QRFs are used with single degree of freedom parameter identification techniques. "

Published: June 2023

"Crude oil extracted in Romania has different pompability characteristics, depending on their formation period (they can be asphalt or paraffin). One method of improving pompability is that in which various additives are used to reduce the freezing point and/or viscosity. These mixture additives may be polymers or other chemical agents. The role of the additives is to reduce the precipitation of the paraffin crystals in the solution by keeping the paraffin molecules as separate entities. This reduces the cohesive forces between the crystals and the adhesion forces between the paraffin crystals and other surfaces. The vast majority of modifiers proposed as oil depressants are macromolecular compounds. The purpose of this article is to analyze the effect of additives on the property of crude oil. "

The dimethyl ether (DME) is an environmentally friendly fuel, that can replace succesfully the petroleum Diesel in engines, or the LPG fuel. In the last period, the world production of DME was steadily rising, with annual rates of 5-8%. The actual commercial technologies producing DME are based on the methanol etherification (the two-step process). An important research effort was expensed in last decennia, in the development of technologies transforming directly the synthesis gas into DME, without separation of the intermediary methanol (the direct or one-step process). This work presents data related to the direct DME synthesis technologies from synthesis gas, thermodynamic particularities of the chemical process and design issues of multi-tubular fixed bed catalytic reactor for gas phase DME synthesis. It is proposed a new constructive solution of the synthesis reactor, with the reactor divided in multiple zones, having distinct catalyst compositions and cooling characteristics. The simulation calculations evidenced the important increase in DME production that can be achieved by this constructive solution, as consequence of an improved control of process evolution along the catalytic reactor.

The presence of protein compounds in wine leads to decreased organoleptic quality of finished products such as clarity and hue. These compounds have important nutritional values. A large part of the proteins present in wine are closely related to the pathogenesis process. Disturbance in wine samples occurs as a consequence of the presence of several non-protein factors such as the presence of phenolic compounds, metals and pH. To date, a wide range of procedures are known for the protein of wine precipitation in order to determine the total protein content of wine samples, using solutions such as: trichloroacetic acid (TCA), acetone, ethanol, etc. Numerous techniques specific to the process of protein stability are also known and developed. The best known techniques for determining protein stability are: thermal with the addition of chemicals, bentonite, tannin, ProtoCheck, acetone respectively combined (hot test + tannin, etc.).

Published: June 2023

Flooding in the Philippines occurs annually in many areas and in varying frequencies and magnitude. Located along the cyclone path, the country suffers from floods and other water induced disasters. In late September and early October 2009, Tropical Storm Ketsana ("Ondoy") and Typhoon Parma ("Pepeng") hit the country in succession and inflicted extensive casualties and physical damage to the country. Tropical Storm Washi ("Sendong") in December 201'1 severely devastated Cagayan de Oro City in Southern Philippines, wiping houses and claiming lives on the island formations in the river area. Again, in December 2012 the city was hit by Typhoon Bopha along with other provinces in Mindanao Island. The country suffered severe devastation from super typhoon Haiyan (locally known as Typhoon Yolanda), which wreaked havoc in the Visayas and South Luzon regions on November 8, 2013. The extreme event turned out to be one of the strongest storms to make landfall in history. The Department of Public Works and Highways (DPWH), at the forefront of mitigating the impacts of water related hazards through the provision of structural measures, is constantly challenged to provide efficient and innovative technologies to address current and emerging risks. This paper describes the country's integrated flood risk management approaches and DPWH's thrusts, programs, policies and strategies towards the establishment of resilient communities.

Published: June 2023

The DegreePlus program at Western Carolina University is a newly developed initiative to help students develop transferable skills, including professionalism, cultural responsiveness, leadership and teamwork, by attendance at specific extracurricular events. The program was first implemented in the 2017-2018 academic year as a pilot with Honors College students, conditionally admitted students and students in specific living-learning communities. Participation by these student groups was encouraged through targeted marketing, transition courses, required attendance at DegreePlus events, and gamification. This research addresses how these methods impacted student participation. We concluded that requiring early participation influenced some students to continue their involvement in DegreePlus, and gamification helped students get interested in the program, but students also recognized the intrinsic value of the program and planned to continue their involvement. Targeted marketing helped to increase awareness and understanding of the program and how it works.

Published: June 2023

Background: We tried to understand whether or not there are some relationships between irritable bowel syndrome (IBS), chronic gastritis (CG), depression, and various inflammatory processes in the body. Method: Consecutive patients with IBS and age and sex-matched control cases were included. Results: The study included 936 patients with IBS (592 females) and 346 control cases. Mean age of the patients was 41.0 years, and 63.2% of them were female. Although gastric sample biopsies were taken just in suspected cases, CG was diagnosed nearly in all of the patients with the IBS (80.4% vs 15.0%, p<0.001). Interestingly, prevalence of antidepressants use was also higher in the IBS cases, significantly (46.4% vs 16.1%, p<0.001). Similarly, smoking (35.2% vs 20.8%, p<0.001), hemorrhoids (37.1% vs 7.2%, p<0.001), and urolithiasis (22.0% vs 9.5%, p<0.001) were all higher in the IBS patients, again. Beside that the mean values of fasting plasma glucose (FPG) (111.9 vs 105.4 mg/dL, p= 0.002) and plasma triglycerides (167.0 vs 147.3 mg/dL, p= 0.013) were also higher in the IBS patients, significantly. Conclusion: Because FPG and triglycerides are well-known acute phase reactants in the body, IBS and CG may be some low-grade inflammatory processes initiated with anxiety, depression, infection, inflammation, trauma, and cancer fear-like stresses of the body, and eventually terminate with hemorrhoids and urolithiasis. Due to the highly significant associations between IBS, CG, and depression, IBS and CG may actually be the two sides of the same paper, and just be two examples of depression-induced various inflammatory processes in human body. Key words: Depression, irritable bowel syndrome, chronic gastritis, irritable gastrointestinal syndrome, smoking, fasting plasma glucose, triglycerides

Strukturwandel der rechtswissenschaftlichen Wissensproduktion – Rechtsempirische Analyse gerichtlicher Verweise auf Blogs in der Corona-Pandemie –
Authors: Hering Laura , Kunz Raffaela
Published: June 2023

Während der Corona-Pandemie haben Gerichte rechtswissenschaftliche Blogs in nie zuvor dagewesenem Maße konsultiert und zitiert – dies das eindeutige Bild, das sich bei einer systematischen Auswertung von Gerichtsentscheidungen deutscher Verwaltungs- und Verfassungsgerichte während der Anfangszeit der COVID-19-Pandmie ergibt. Hat die Pandemie Blogs als wissenschaftlichem Format damit endgültig zum Durchbruch verholfen? Dieser Frage möchten wir im vorliegenden Beitrag nachgehen. Die Untersuchung bestätigt, dass die besonderen Umstände der Pandemie die neuen Zitiergewohnheiten begünstigt haben. Das „schnelle Format“ des Blogs, in dem Argumentationslinien vorausgedacht wurden, war in einer Zeit, die von Schnelllebigkeit und Wissensdefiziten geprägt war und mit der Printpublikationen nicht Schritt halten konnten, unumgänglich. Gleichzeitig spricht vieles dafür, dass Blogs die errungene Autorität nicht mehr einbüßen werden. Die Zahlen bestätigen allerdings auch, dass Blogs sich dem System der Wissensproduktion stärker angepasst haben als dieses grundlegend zu verändern.

Published: June 2023

Introduction: Multiple myeloma (MM) is a neoplastic proliferation of immunoglobulin-producing plasma cells that have multiple presentations due to the infiltration of plasma cells in the bone marrow and other organs. Common manifestations include anemia, bone pain, fatigue, and hypercalcemia. MM presented with rectorrhagia is very rare. Case Presentation: A 74-year-old woman with a history of rectorrhagia episodes from about nine months ago presented with severe anemia, weakness, and lethargy. The findings of endoscopy and colonoscopy did not justify the patient's manifestation, and finally, due to thrombocytopenia and anemia, a bone marrow biopsy was performed, and multiple myeloma was diagnosed. Conclusions: Although GI bleeding in Multiple myeloma is a very rare manifestation, this diagnosis must be considered in the differential diagnosis of patients with unexplained and refractory GI bleeding.

Published: June 2023

Introduction: Biosurfactants or surface-active compounds with amphiphilic molecular structures, including a hydrophilic and a hydrophobic domain, are produced by microorganisms. These compounds increase the biodegradation of hydrocarbons in the environment due to their ability to emulsify hydrocarbon-water mixtures. This study was conducted to isolate and characterize biosurfactant-producing bacteria from the samples of Gastropods. 

Materials and Methods: The gastropod samples were collected from oil-contaminated sites in the Persian Gulf, Middle East. Biosurfactant-producing strains were isolated from these samples. The biosurfactant production ability was analyzed using Drop Collapse TEST, oil spreading test, emulsification activity test, and BATH test.

Results: In total, 11 biosurfactant-producing strains were isolated. Two isolates with higher growth rates and biosurfactant production ability were selected for further studies. The best isolates were identified as Halomonas sp. isolate BHA16 and Vibrio alginolyticus isolate BHA 17 based on molecular analysis. Gas chromatography analysis of remaining crude oil confirmed that these strains could degrade to 51.44 % and 67.58% of crude oil, respectively.

Conclusion: The results of this study indicated the surfactant activity of the bacterial strains isolated from Gastro pods had a good potential for the biodegradation of crude oil and could be used for the cleanup of oil-contaminated marine environments.

Introduction: Diesel oil is the most used petroleum product in Iran and other countries. The majority of diesel oil is stored in underground reservoirs and Fuel stations. This product can heavily pollute the adjacent soil. Diesel oil pollution has some ecological effects on soil that disturb the composition and diversity of the microbial community. The present research aimed to investigate the effects of diesel oil pollution on two different types of soil.
Materials and Methods: To examine the effects of diesel oil on microbial communities, two different types of soil (industrial and forest types) were collected from Kerman province, Iran. Six microcosms were designed based on three microcosms existing in each type of soil, including unpolluted microcosm, polluted microcosm, and polluted microcosm with nutrients (Nitrogen and Phosphor). Some factors were assayed in each microcosm during 120 days of the experiment. These factors included total heterotrophic bacteria, total diesel oil-degrading bacteria, dehydrogenase enzyme, and diesel oil biodegradation.
Results: The quantity of diesel oil-degrading bacteria was significantly lower than heterotrophic bacteria in all soil microcosms. The quantity of diesel oil-degrading bacteria had a decrement pattern until day 60 of the experiment, but after that, these bacteria had an increment pattern. The best dehydrogenase activity between different microcosms was related to polluting microcosms with diesel oil except for farmland soil. The highest biodegradation of diesel oil in all studied soil types belonged to the industrial microcosm (95%). Statistical analysis of the results indicated a significant correlation between the most probable number quantity of heterotrophic bacteria and other assayed factors. Forest soil was significantly different from other soil types.
Conclusion: Given the obtained results of the current research, that forest soil is more sensitive to diesel oil pollution, compared to industrial soil. It is, therefore, possible to propose appropriate strategies for the bioremediation of different studied soil types.

Introduction: Increasing the concentration of Boron in drinking water, wastewater, and irrigation have negative effects on the human environment. This pollution can be partially removed by the application of phytoremediation technologies using algae or aquatic plants. The aim of the current study was to determine the biosorption capacity of the algae Spirogyra sp. for Boron from industrial wastewater and examine the best elimination conditions using different parameters.

Materials and Methods: In this study, 100 g of fresh algal biomass was collected from the industrial wastewater of a copper mine located in Kerman, Iran.

At first, algae was selected among various algal species concerning abundance and resistance ability to high concentrations of Boron. Then, removal of Boron by the algal was examined in terms of algae biomass levels (2 and 4 gr), incubation time intervals (2, 12. 24. 48, and 72 hours), and different concentrations of Boron (5, 10, 15, 25, and 100 ppm) on the were examined. The experiment was factorial with a completely randomized design framework and three replications.

Results: The results presented that the elimination of Boron from industrial wastewater was performed by biomass of algae Spirogyra sp. The maximum Boron absorption was achieved at concentrations of 5 ppm and an incubation time of 12 hours. The absorption of Boron was higher in 4 gr than in 2 gr of algae biomass treatment.

Conclusion: It can be concluded that algae Spirogyra sp. has a strong potential for boron removal in industrial wastewater containing boron ions.
Factors affecting academic burnout and job performance: A study of married working women in Vietnam
Authors: Vo Thuy Thanh Tam
Published: June 2023

Retaining and managing talented employees are extremely meaningful efforts for organizations to ensure their competitive advantage. In Vietnam, more and more women have been holding important roles in national and foreign companies. However, Vietnamese women must also balance the quality of their roles as wives and mothers. This creates psychological pressure and causes difficulties for married working women. This paper aims to examine the factors affecting academic burnout and job performance of married working women. Using data collected from 343 respondents, we found that academic burnout was inversely related to core self-evaluation and positively related with work-family conflict (and family-work conflict), whereas job performance was directly proportional to core self- evaluation and inversely proportional to work-family conflict (and family-work conflict). The findings suggested that married working women need an optimistic self-view to deal with conflicts between job and family more easily, and to reduce academic burnout, and improve job performance.
Differentiated learning and evidence from neuroscience: Some implications for Computer-Assisted Language-Learning (CALL) pedagogies
Authors: Ania Lian
Published: June 2023

Recently, due to the developments in medical technology, the field of neuroscience has been expe- riencing an unparalleled growth, resulting in many breakthroughs in the field’s understanding of how the brain learns and constructs information. The aim of this paper is to review the key findings of this research and propose implications for designing research in CALL. The findings are reviewed against the backdrop of a critique of current CALL research, which continues to show resistance to change and seems unable to offer new directions to second language (L2) pedagogues. This is a conceptual paper that hopes to inspire CALL scholars and postgraduate researchers to expand the traditional sources of the literature that define the scope of L2 studies and to integrate evidence from emerging research in order to modernise the field and its implications for practice.

Pada Putusan Nomor 167/Pid.Sus/2021/PN Krg, restistusi yang dibayarkan pelaku kepada anak sebagai korban tindak pidana persetubuhan anak dianggap tidak adil dan tidak dapat memulihkan hak korban yang ditambah munculnya subjek hukum baru akibat perbuatan mereka. Apalagi dalam perhitungan pembayaran restitusi yang ditetapkan oleh hakim tidak terdapat tolak ukur sebagai pedoman pemberian restitusi. Dengan demikian ada kekosongan hukum yang berkenaan dengan pertimbangan hukum hakim yang seharusnya membahas tentang restitusi. Penelitian ini bertujuan untuk mengetahui tinjauan yuridis dan eksistensi perjanjian sewa menyewa terhadap perkara wanprestasi. Penelitian ini termasuk penelitian hukum doktrinal (normatif) yang sifat penelitianya preskriptif dengan Pendekatan kasus (case approach) dengan mengkaji pertimbangan kasus yuridis. Hakim dalam pertimbangan hukumnya tidak memberikan aspirasi terhadap restitusi yang dibayarkan. Dengan demikian ada kekosongan hukum yang berkenaan dengan pertimbangan hukum hakim yang seharusnya membahas tentang restitusi.
Kurangnya Partisipasi Masyarakat Dalam Upaya Penertiban Tanah Telantar di Kabupaten Demak
Authors: Habib Hauri Samba , Marsoyo Agam
Published: June 2023

Sangat sedikit topik penelitian yang mengambil perspektif partisipasi masyarakat dalam upaya penertiban tanah telantar. Padahal, peran serta masyarakat sangat dibutuhkan untuk menjamin keberlangsungan tata ruang sekaligus sebagai komponen yang secara langsung dipengaruhi oleh dinamika tata ruang khususnya aktivitas penggunaan lahan. Penelitian ini akan menunjukkan sejauh mana partisipasi masyarakat dalam membantu otoritas pertanahan untuk menertibkan tanah yang terindikasi telantar. Penelitian ini dilakukan melalui pendekatan kualitatif untuk menginterpretasikan pengalaman masyarakat di sekitar lokasi tanah terindikasi telantar secara kritis. Hasil penelitian menunjukkan bahwa partisipasi masyarakat terhadap isu publik ini masih kurang. Sikap pasif dan ketidakpedulian masyarakat ini menjadi bukti bahwa proses penertiban tanah telantar belum menjadi perhatian khusus di kalangan masyarakat pedesaan. Artinya, kesadaran masyarakat desa dalam upaya pengendalian penggunaan lahan belum terbangun sepenuhnya.
