Published: September 2021

The initiatives of the Government of the Russian Federation concerning the clarification of the rules for the provision of paid medical services are considered. For medical budget institutions, it is significant that such services are proposed to be regulated not only by the Federal Law “On the Basics of Public Health Protection in the Russian Federation”, but also by the Law of the Russian Federation ”On Consumer Rights Protection”. A comparative analysis of the previous and new versions of the Rules for the Provision of Paid Medical Services by medical organizations is carried out. The financial aspects of the activities of budgetary medical institutions, their property rights and the limits of the exercise of these rights are considered. The new requirements to the form and content of the contract for the provision of paid medical services, the features of the remote method of its conclusion are considered.
ANALISIS KUALITAS PELAYANAN TERHADAP KEPUASAN KONSUMEN (Persepsi Konsumen Hotel Golden Tulip Tangerang)
Authors: Pratopo Pandji
Published: September 2021

Hotels are an element of the tourism industry and play a very important role in providing services to tourists. Each hotel tries to improve its facilities and service quality. If consumers enjoy services that are much lower than they expected, consumers will lose interest in these service providers, and the hotel will eventually lose customers. Conversely, if consumers enjoy services higher than their expectations, then consumers will feel satisfied. Based on the research background, the questions that arise in this study are which factors have the most influence on customer satisfaction on the service quality of the Golden Tulip Hotel Tangerang, and what factors have the greatest influence on customer service expectations of the Golden Tulip Hotel Tangerang. The research model developed in this study consists of four dimensions, namely service quality, consumer expectations, and customer satisfaction, with two hypotheses to be tested. The test was carried out using the Structural Equation Modeling (SEM) analysis tool in the LISREL program on 100 respondents who were consumers of the Golden Tulip Hotel Tangerang. The results of data analysis indicate that the two proposed hypotheses are acceptable, and it can be concluded that service quality has a positive effect on customer satisfaction, and consumer expectations have a positive effect on customer satisfaction. This study also links the research results with the theoretical implications and policies of the Golden Tulip Hotel Tangerang management, which are described in the conclusion section. Research limitations and future research agendas can be used as a reference for future researchers.

PELAYANAN PEMBAYARAN PAJAK KENDARAAN BERMOTOR MELALUI E-COMMERCE MENUJU GOOD GOVERNANCE
Authors: Azahari Helmi
Published: September 2021

This study aims to find out how e-commerce is a tool to improve public services, especially for motor vehicle tax payments. The essence of innovation to serve the public is how to provide improved services to the public according to advances in information technology. Previous research related to public services has revealed more about the analysis of public services (Rinaldi, 2012) or public service innovations (Hartomi et al, 2018). However, this study aims to determine whether the payment of motor vehicle taxes through e-commerce is included as an effort to provide good public services to achieve good governance. According to the theory of public service management, what is called good governance must meet the needs of the community for public services, namely participation, rule of law, transparency, responsiveness, orientation to consensus, equality, effective and efficient operation, accountability and strategic vision. This research uses a qualitative method with a case study approach. The results show that the motor vehicle tax payment service through Bukalapak in the Bekasi City area, West Java, has met most of the criteria to serve the public well.

The issues of organization of the process of slow pyrolysis of organic substances, in the general case of unknown and variable composition, are considered. The relevance of the work is determined by considering the possibility of using various organic waste (domestic, agricultural, industrial) without their preliminary sorting and drying to obtain secondary energy resources of a known (controlled) composition. The novelty of the work is due to the development of a model for the method of controlled pyrolysis or gasification of organic substances with a minimum amount of solid residues at a maximum calorific value of the resulting mixture of combustible gases. A process based on filtration combustion in superadiabatic mode is considered. In existing devices, when this mode is implemented, a counter flow of the feedstock and reaction products is organized. As a result, a part of the water vapor generated at the drying stage is part of the mixture of reaction products and, accordingly, reduce their energy value. The scheme of the process proposed for consideration is based on the organization of the associated flow of feedstock and reaction products. As a result, the resulting carbon dioxide and water vapor are used as additional oxidizing agents. As a result, the carbonaceous residue decreases with a simultaneous increase in the composition of the mixture of gaseous products of carbon monoxide and hydrogen. A scheme for real-time monitoring of the composition of the feedstock during pyrolysis (gasification) is proposed. Knowledge of the composition makes it possible to control the process of its processing in order to: a) organize the optimal gasification process in terms of maximizing the amount and energy value of the mixture of gaseous reaction products; b) control the consumption of the processed feedstock in order to produce the required amount of product gas at any given time.

Published: September 2021

Iron and manganese accumulation in drinking water reservoirs is a challenging issue and should be controlled to prevent their adverse effects on human health. Accumulation of these elements not only clogs pipeline systems but also causes stains on fixtures and laundry. Also, high concentrations of iron and manganese may lead to various health problems when ingested. This study focuses on the release mechanism of iron and manganese from sediments to the water column in reservoirs and investigates methods to prevent this release. Effects of hypoxia, hypolimnetic aeration, alkalinity of water, and thermal stratification on iron and manganese concentrations were investigated through laboratory experiments. Experiments done simulating the water column showed that hypoxia caused more dissolution of ferrous iron when compared with that of manganese. Accordingly, aeration of the water column in hypoxic conditions lead to a significant decrease in ferrous iron concentrations (in our case reaching zero). However, manganese and total iron levels were not affected by the aeration of the water column. Alkalinity level of the water column was observed to have a great effect on the solubility of iron and manganese. Concentrations of total Fe and total Mn measured for acidic (pH=5) conditions were considerably greater than concentrations measured at neutral conditions. As for alkaline (pH=11) conditions, the opposite was observed with measured concentrations of total Fe and total Mn being lower than the ones measured for neutral conditions. Thermal stratification had an enhancing effect on the solubility of both iron and manganese ions. While aeration of the stratified water column slightly decreased the concentrations of Total Fe and Mn, it had a greater impact on decreasing Fe2+ concentrations.

The phenolic composition of the skin of the Băbească neagră grapes grown in south-eastern Romania was studied by two extraction techniques, i. e., ultrasound-assisted extraction (UAE) and enzyme-assisted extraction (EAE). This study aimed to analyze the grape skin bioactive compounds and the antioxidant potential using ethanol of three different concentrations 50%, 70%, and 96% and acidified with acetic, citric acid, or hydrochloric acid. This research aimed to maximize the extraction of bioactive compounds from red grape skin by using commercially available oenological enzyme preparations, varying the enzyme dosage, pH, temperature and extraction time. The results indicated that the highest total anthocyanin content was obtained when using 70 % ethanol extract acidified with 0.1 N hydrochloric acid, characterized by 4.29±0.04 mg C3G/g DW for ultrasound extraction and 2.54±0.13 for enzyme-assisted extraction. The results of antioxidant potential of the extracts investigated showed that the 96% ethanol extract had the highest antioxidant activity (18.76±0.24 mM of Trolox/g DW), followed by the 50% ethanol extract and 70% ethanol extract (16.35±0.79 and 16.48±0.54 mM of Trolox/g DW, respectively). The results disclosed that the highest extraction yield for antioxidant activity quantification was obtained by cellulase (61.48±1.19 mMol Trolox / g DW) after only one hour of extraction.

Authors: Cakmak Hulya , Ozyurt Vasfiye Hazal
Published: September 2021

Carrot is an important crop by containing bioactive compounds such as carotenoids, vitamins and dietary fiber. But the shelf life of fresh carrot is limited due to its moisture content. The aim of this study was to evaluate the effects of using different amounts of egg albumen (EA) and whey protein isolate (WPI) and their interactions on carrot juice foam stability. For this purpose, the experimental design was built by response surface method and employing EA amount (5-10-15%), WPI amount (0-5-10%) and whipping time (4-6-8 min) as independent variables, while selecting the density and overrun as foam stability evaluation criteria. Among the tested levels of independent variables, the lowest density (0.2433 g/ml) and the highest overrun value (2.3466) was observed for 15% EA with 10% of WPI incorporation and the 8 min whipped foam. The levels of EA and/or WPI were found significantly effective on the selected responses (p<0.05), however only the interaction of whipping time with WPI amount had significant effect on density and overrun values. The foam stability improvement with WPI incorporation was confirmed by air bubble diameter distribution analysis, and the lowest average foam diameter with more homogeneous diameter distribution was obtained for 15% EA+10% WPI foam.

Authors: Ergin Firuze Emilia
Published: September 2021

In this study, the effects of the incubation temperature and type of starter culture on the physical properties, including graininess and visual roughness, of ayran were determined. Ayran samples were produced from milk inoculated with two different starter cultures (Yo-Mix 410, Yo-Mix 883) and incubated at temperatures of 37 or 45°C, and then stored at 4°C for 15 days. As incubation temperature decreased the number and perimeter of grains and syneresis decreased and the amount of exopolysaccharide (EPS) increased in ayran samples. The high amount of EPS resulted in low syneresis value, the number and perimeter of grains and visual roughness in ayran samples. The apparent viscosity and consistency coefficient values of ayran samples produced from milk incubated at 37°C were higher than those from milk incubated at 45°C. The Power law model was found more satisfactory to describe flow behaviour of all ayran samples. The rheological properties of ayran samples changed with measurement temperature. As the measurement temperature increased from 5°C to 15°C, the apparent viscosity and consistency coefficient values of ayran samples were significantly decreased. The activation energy values for apparent viscosity of ayran samples varied depending on the incubation temperature, type of starter culture and storage period.

Published: September 2021

White, red and black glutinous rice are common rice cultivars used as raw materials for food products in West Sumatera, Indonesia. The characteristics of these three cultivars are different, and thus there is a need to elucidate the differences. The characterization of physicochemical and antioxidant properties of these three local cultivars was performed in this study. Three local glutinous rice paddy cultivars were milled to obtain brown glutinous rice. The results showed that black glutinous rice had higher ash content, total dietary fiber, total phenolic content, total flavonoid components, total anthocyanin content than other cultivars. Having higher phenolic, flavonoid, and anthocyanin content, the black glutinous rice consequently had higher antioxidant activity than white and red glutinous rice. Moreover, white glutinous rice had higher fat content and amylose content, and had higher starch digestibility amongst others. The highest protein content was obtained from red glutinous rice. The pasting properties, fatty acid compositions, and amino acid compositions of each glutinous rice were also determined and the results showed distinct profiles between the cultivars.

Published: September 2021

Staphylococcus spp. are the important bacterial agents of subclinical and clinical mastitis cases. This study was aimed to determine the vancomycin resistances, antibacterial resistance profiles, some virulence genes, and pheno- and genotyping of staphylococci from mastitis. For this aim, 121 staphylococcal isolates were analyzed. The identifications of isolates were confirmed with PCR for being Staphylococcus spp. and Staphylococcus aureus. The antibiotic resistance patterns were determined by Kirby bauer Disc Diffusion Tests and according to the resistance profiles, the isolates were antibiotyped. The vancomycin resistance genes were determined by PCR for investigating the vanA, vanH, vanR, vanS, vanZ, vanY and vanX genes. The vancomycin resistant isolates were genotyped with RAPD-PCR. The nuc gene was detected in 86 of 121 staphylococcal isolates examined and named as Staphylococcus aureus. The remaining 35 isolates were defined as Staphylococcus spp. S. aureus isolates were found to be resistant to penicillin G, amoxicillin/clavulanic acid, oxacillin, tetracycline, cefaperazone, teicoplanin, vancomycin and trimethoprim-sulfomethaxazole at 50% (43/86), 40.7% (35/86), 34.9% (30/86), 23.3% (20/86), 22.1% (19/86), 18.6% (16/86) 10.5% (9/86) and 8.1% (7/86) respectively. On the other hand, 4 (11.4%) of 35 Staphylococcus spp. isolates were resistant to penicillin G, 3 (8.6%) to amoxicillin/clavulanic acid, 2 (5.7%) to trimethoprim-sulfometaxazole, 1 (2.9%) to oxacillin, cefaperazone, teicoplanin, while all isolates were sensitive to vancomycin and tetracycline. Of the 9 S. aureus isolates that were phenotypically resistant to vancomycin, vanA gene was detected in 2 and vanR gene in 3 isolates. Multiple resistances to three or more antibiotics were determined in 42 of 86 S. aureus isolates. In addition, coa gene was detected in 61 (70.9%) of 86 S. aureus isolates. 10 different gene polymorphisms were detected in coa gene positive isolates. While the spa gene was determined in all S. aureus isolates, it was revealed that they had 4 spa gene polymorphisms. Nine different genotypes with a similarity between 51-75% were detected in the genotyping of vancomycin resistant 9 isolates. In conclusion, multiple antibiotic resistance rates in S. aureus isolates investigated were found to be important for mastitis treatment. The results obtained from this study show that milk and dairy products containing these factors pose a public health risk due to the determination of vancomycin resistance in mastitis-derived Staphylococcus strains.

Tujuan dari penulisan ini adalah untuk mengetahui kedudukan pengawasan eksternal dalam BUM Desa berkaitan dengan hal-hal apa saja yang dapat dilakukan oleh pengawas eksternal. Metode penelitian yang digunakan dalam penulisan ini adalah metode yuridis-normatif, dengan menggunakan pendekatan peraturan perundang-undangan, kasus, dan konseptual. Dalam tulisan ini ditemukan bahwa desa menggunakan dua konsep pengawasan yakni secara internal dan eksternal. Pengawasan internal merupakan pengawasan yang berasal dari desa dan diatur melalui PP No 21 Tahun 2021 tentang BUM Desa, sedangkan pengawasan eksternal yang berwenang untuk mengawasi BUM Desa merupakan pemerintah daerah yang diwakilkan oleh inspektorat serta Badan Pemerika Keuangan. Tulisan ini berkesimpulan bahwa pengawas eksternal memiliki kewenangan untuk melakukan audit dengan kewenangan pemberian sanksi yang berbeda. Inspektorat memiliki kewenangan memberikan sanksi administrasi sedangkan bagi BPK tidak memiliki kewenangan untuk memberikan sanksi administrasi. Kedua pengawas ini pun tidak memiliki akses untuk menindak persoalan pidana karena harus diberikan kepada aparat penegak hukum sebagai yang berwenang. Kedua pengawas ini pun memiliki peran penting untuk mengoptimalkan pengawasan sehingga BUM Desa dapat berjalan secara akuntabel.

Published: September 2021

On-campus Higher Education is often assumed to be educationally richer than online learning due to opportunities for face-to-face interactions with students and instructors. However, the assumption that the presence of other learners enhances educational experiences requires formal interrogation. In this study, we use the Community of Inquiry (CoI) framework to evaluate the nature of social presence at a 500 delegate undergraduate conference that is the culmination of capstone final year dissertation projects. We find that students do not perceive social presence to their learning during their dissertation work, but that presentation of dissertations in the conference environment can initiate educationally valuable social interactions. Notably meaningful interactions occur between students of different year groups, allowing students insight into future tasks and to reflect on the progress they have made over their course. We encourage educators to consider the opportunities that undergraduates have for meaningful interaction in all on-campus experiences, as social components of learning cannot be assumed.

Seed germination is generally the critical step in seed establishment and thus the determination of successful crop production. This study was focused at examination of the biochemical and germination parameters effected by low water potential which was generated by polyethylene glycol (PEG) 6000 and mannitol, related to drought stress and growth of Waha durum wheat genotype. Two tests were carried out in a growth chamber; the first comprises seed germination into Petri dishes in the presence of different concentrations of the two osmoticums (0, 5, 10, 15 and 20 % of PEG6000 and mannitol). The second test was carried out in nutrient solution BD medium. Our results shows that Both PEG -6000 and mannitol reduced germination. Therefore, a rapid increase was observed in the rate of germination both for the control plants and the plants subjected to a concentration of 5 g/L and 10 g/L and changes in proportion to the time. For the concentration of 15 g/L and 20 g/L, this phase is very short, which explains the reduced germination rate due to the inhibitory effect of the two osmoticums on germination. In this study, PEG-6000 treatments resulted in an increase of some proteins and a decrease of others. Waha displayed 12 bands for control plants, 40 bands for PEG-6000 stressed plants (all treatments) and 35 bands for mannitol treatments.

Forests have many insect species that are unique to biodiversity and play a crucial role in the functioning of ecosystems. Forest cockroaches are the best example of forest litter insects, which also help decompose fallen leaves. The composition of the Blattoptera fauna can vary from one region to another, depending on the habitat and numerous biotic and abiotic factors In order to study the diversity, abundance, and distribution of forest cockroaches in different Algeria ecosystems, we have selected four sites from three Wilayas: Senalba (Djelfa), Ain achir (Annaba), Seraidi (Annaba), and Lehnaya (El-taref). These sites are classified into two distinct forest groups (Pinus halepensis and Quercus canariensis). In all areas, the samples were collected each month manually, starting from April 2019 until March 2020. We have collected 1231 individuals of cockroaches and describe eight species from all locations: Loboptera ovolobata (Bohn, 1991), Loboptera decipiens (Germar, 1817), Ectobius kervillei (Bolivar, 1907), Dziriblatta nigriventris (Chopard, 1936), Dziriblatta stenoptera (Chopard, 1937), Phyllodromica zebra (Rhen, 1903), Dziriblatta sp. (Chopard, 1936) and some Ectobius (Stephens, 1835) specimens have not yet been identified. With 51% L. decipiens was the most abundant species, followed by L. ovolobata with 27%. Despite that, the number of larvae was substantially higher than the number of adults in all forests examined. However, the abundance and biodiversity of cockroaches in the Djelfa forest were greater than those of the other woods. This study made it possible to characterize the diversity and dynamics of cockroach species populations in different Algerian ecosystems according to diverse Mediterranean forests.

Hajj pilgrims must have certain vaccines for pilgrimage; these requirements aim to reduce the spread of infectious diseases. This study analyzed the trends in vaccine adherence for meningitis, yellow fever, and polio from January 2017- December 2019. These trends can help in guiding future policymaking to prevent outbreaks during Hajj and similar mass gatherings. We analyzed data using descriptive statistics for Hajj pilgrims and Hajj seasonal workers arriving in Saudi Arabia over three years (2017–2019). Health Control Centers (HCCs) collected data at points-of-entry (PoE) and entered it into Saudi Arabia’s Health Electronic Surveillance Network (HESN). We reviewed HESN data to collect information on total passengers arriving per country and the number of passengers vaccinated for: meningococcal meningitis, poliomyelitis, and yellow fever. We compared data to identify the difference in vaccination by region.  We used chi-square tests to assess differences in compliance rate among these travelers by year and country of origin. The number of participating countries increased from 113 to 132. Meningitis vaccine coverage increased by 5% from 2017–2019. The increase was not statistically significant. Asia had the lowest overall adherence rate (83%). Yellow fever adherence decreased significantly using a difference of mean adherence between 2017 and 2019 (p-value 0.01). Polio vaccination adherence decreased by 5% from 2017 to 2019; this was not significant (p-value = 0.08). The vaccine coverage increased for meningitis and decreased for yellow fever and polio. Less than 100% vaccine adherence among Hajj travelers creates the potential for the spread of infectious diseases. Proof of vaccination should be required in submitted visa applications. Countries of origin and Saudi Arabia must work together to ensure that all Hajjis are adequately vaccinated before departure.
Optimal Placement of UAV-Assisted Amplify-and-Forward Relays for Mitigation of Pointing Error in Optical Wireless Backhaul
Authors: Bashir Muhammad Salman , Alouini Mohamed-Slim
Published: September 2021

The angular instability of unmanned-aerial-vehicle (UAV) relays as well as the turbulence-induced beam wander may lead to significant pointing error in free-space optical backhaul. The hop distance between each relay in a serial relay scheme is an important parameter that can be optimized in order to enhance the performance of the system. In this study, we have optimized the error and outage probabilities as a function of the hop distance vector for amplify-and-forward relays (AF) under a number of constraints such as the maximum and average relay power and the maximum relay gain. We have discovered that for the unconstrained optimization problem, the optimum hop distances is a strictly increasing sequence for both the error and outage probabilities. For maximum power constraint optimization, the optimum hop distances form a strictly increasing sequence, whereas for maximum gain constraint optimization, the optimum hop distances lead to a nondecreasing sequence.

Stabilizer codes, introduced in [2], [3], have been a prominent example of quantum codes constructed via classical codes. The paper [3], introduces the stabilizer formalism for obtaining additive quantum codes of length n from Hermitian self-orthogonal codes of length n over GF(4). In the present work, we reinterpret the stabilizer formalism by considering binary codes over the symbol-pair metric (see [9]). Specifically, the present work constructs additive quantum codes of length n from certain binary codes of length n considered over the symbol-pair metric. We also present the Modified CSS Construction which is used to obtain quantum codes with parameters.

Published: September 2021

Fats, oils and greases in waste water frequently cause serious environmental problems. A commercial preparation was tested for its ability to degrade oil and grease in wastewater. As substrates, two fats (lard and beef fat) and four oils (rape seed oil, sunflower oil, palm oil and olive oil) were chosen. The degradation ability of commercial preparation for different substrates was investigated by the determination of lipid degradation at pH 7, temperature 25 °C, aerobic condition and agitation at 160 rev/min for 14 days in Erlenmeyer flasks. Simultaneously, the lipolytic activity was spectrophotometrically determined at 420 nm. All tested substrates were degraded by the different rate to basic units (fatty acids).

Evaluating the water chemistry in the primary circuit and the effect of chemical econtamination

of the heat exchanger tubes performed by the AP-CITROX (AP: alkaline permanganate; CITROX: citric and oxalic acid) procedure at Paks NPP (Hungary), a project dealing with the comprehensive investigation of the general corrosion state of the steam generators (SGs) has been initiated. Owing to the fact that there is no investigation method available for the in-situ monitoring of the inner surfaces of heat exchanger tubes, a research program based on sampling as well as on ex-situ electrochemical (voltammetric) and surface analytical measurements (SEM-EDX, CEMS, XRD, XPS) was developed and elaborated. In the time period of 2000-2008 - within the frame of the above project - 45 stainless steel specimens, cut out from various locations of the steam generators of the Paks NPP were investigated. Based on the measured corrosion characteristics (corrosion rate, thickness and chemical composition of the protective oxide-layer) it was found that these parameters are strongly dependent on the decontamination history of steam generators. The present work gives a brief overview on the general corrosion state of the heat exchanger tubes of SGs, concerning the long-term effects of the AP-CITROX procedure on the chemical composition and structure of the protective oxide-layer.

Authors: Kavšek Darja , Brodnjak Vončina Darinka
Published: September 2021

The aim of this work is focused on water quality classification of the waste waters and evaluation of pollution by the monitoring measurements during period 2006-2008. Environmental monitoring was performed in the region of Trbovlje, Slovenia, with two sampling sites and 15 chemical and physicochemical water quality parameters (pH, temperature, suspended solids, settling matter, chemical oxygen demand, biochemical oxygen demand, AOX (adsorbable organic halogens), total phosphorus, ammonium, nitrite, sulphate, chloride, fluoride, sulphide and mineral oil content) monitored in monthly periods (total of 60 objects x 15 variables). For handling the results different chemometric methods were employed, such as basic statistical methods for the determination of mean and median values, standard deviations, minimal and maximal values of measured parameters and their mutual correlation coefficients, the principal component analysis (PCA), cluster analysis (CA), and linear discriminant analysis (LDA). Monitoring of general pollution of waste waters and following measuring parameters which are above permitted concentration level can be used for searching of pollution source and for planning prevention measures from pollution, as well. The study allows drawing new information from the data sets such as patterns of similarity between sampling locations, sources of pollution in the environment, seasonal behavior of chemical contents and time trends.

The aim of this study was to find conditions for isolation of antioxidants from Alchemilla xanthochlora. The solid-liquid extraction of plant material with different solvents (n-hexane, chloroform, ethylacetate, methanol, and water) was used for preparation of crude extracts of antioxidants. For additional purification of crude extract, liquid-liquid extraction in different organic solvents (chloroform, ethylacetate, methanol) and water, and column chromatography with silica gel as stationary phase and mixture of chloroform : methanol as mobile phase were used. The content of active compounds was monitored by photometric method and special TLC analysis using DPPH as basic reagent. TLC-DPPH analysis of herbal extracts showed that antioxidants from Alchemilla xanthochlora were separated into two groups with different polarity. Finally, for the isolation of antioxidants from Alchemilla xanthochlora were successfully used the following procedures: extraction of dried grounded plant material with methanol at 50°C during 1 hour, subsequent liquid-liquid extraction in isopropanol and water and fractionation of isopropanol extract by column chromatography. Fraction with isolated antioxidants showed antioxidant activity 535.2 mg to g of fraction residue.

Published: September 2021

According to the latest EU regulations it is necessary to cut down the consumption of chemically based pesticides. Several research programmes are focussed on the study of secondary metabolites of plants, which have antimicrobial or antifungal activity against microbial phytopathogens. Other reasons for using of natural biocides are the growth of resistance of phytopathogens against several pesticides; broaden microbial attacks to significant agricultural product for food industry due to the climate changes. The presentation is focussed on the determination of the contents of secondary metabolitesleaves of several cultivars of hop – polyphenols and flavonoids. Methanol crude leaves extracts were tested on biocide effects against selected microbial phytopathogens.

Ciudad y educación: buscar siempre un saldo pedagógico
Authors: Mockus Antanas
Published: September 2021

Desde ya podemos pensar cómo sería ser maestro en una ciudad educadora. En la ciudad educadora maestros invisibles por dondequiera que pasan siembran conocimiento y autocomprensión, entendimiento y fertilidad comunicativa. Los liderazgos ya no se apoyan en la creación de facciones. Cuando el nuevo maestro, el todo terreno, el de pleno tiempo, no está enseñando es porque está aprendiendo. ¿cómo puede tranformarse un maestro común y corriente en uno de estos maestros invisibles?

Experiencias pedagógicas de colectivos de maestro ¿Expresiones de acción política?
Authors: Martínez Pineda María Cristina
Published: September 2021

El texto busca develar las posibilidades de despliegue de la subjetividad política de los maestros que se suscitan en y desde el desarrollo de experiencias pedagógicas producidas por grupos de maestros que deciden emprender acciones alternativas a las vivenciadas en la cotidianidad escolar. La reflexión se centra en el reconocimiento de algunos eventos que se producen tanto en las interacciones como en las actividades que se generan en el desarrollo de dichas experiencias, y que pueden leerse como factores que agencian y potencian la capacidad de acción política de los maestros. Se trata entonces de una ampliación de la mirada a las experiencias.
Educación y televisión: de la naranja achatada al ciberespacio

Published: September 2021

La importancia de la televisión para la educación resulta inconmensurable. Sus múltiples posibilidades están inexploradas. Su papel en la generación de nuevos métodos y pedagogías es fundamental , sobre todo si propendemos por una educación que se proyecte en la ciudad y sus habitantes. Afortunadamente muchos educadores están trabajando con video, con la programación de la televisión y con otras experiencias comunicativas, allanando el camino para una nueva educación acorde con las nuevas circunstancias, en especial con el hecho de que los jóvenes y niños dedican más tiempo a la televisión que a otro tipo de actividades, entre ellas el estudio en casa.
