Published: March 2022

The paper presents the characteristics of oak and hornbeam pollen seasons in Kielce in 2021. Aeropalinological measurements were carried out with the use of the volumetric method. The main oak pollen season lasted 35 days. The maximum concentration of oak pollen, i.e. 227 grains in 1 m3 of air, was recorded on May 20, and the seasonal pollen index was estimated at 1533. The hornbeam pollen season was longer, i.e. 56 days. The peak hornbeam pollen release was recorded on April 28, when 22 pollen grains in 1 m3 of air were noted, with the annual concentration sum of 207. The study also determined the effect of some meteorological factors on the concentration of pollen grains of the analyzed plant taxa. The meteorological parameters were found to exert the strongest effect on the dynamics of the hornbeam pollen season.

Miles de viviendas construidas y vacías por toda la costa y en el interior; millones de metros cuadrados de suelo clasificado y paralizado; viviendas edificadas ilegalmente en el suelo no urbanizable o en suelos con clasificación o calificación incompatible; indefensión jurídica de miles de ciudadanos europeos ante unas leyes que no comprenden y que dejan fuera de ordenación en el mejor de los casos, unas viviendas compradas con el asesoramiento de bufetes de abogados que daban lustre jurídico a una situación nunca asumida por la administración ni por los administrados que encontraron en la venta del territorio propio el medio de alcanzar un lujo desmedido en un tiempo récord; colapso en la tramitación de figuras urbanísticas de planeamiento general que cuando finalmente son aprobados dan paso con una inmediatez esclarecedora a la modificación de sus parámetros básicos; agentes financieros que deben afrontar la resolución de conflictos jurídicos irresolubles en las fincas o inmuebles recibidos en pago por la falta de liquidez de empresas y usuarios y que habrían sido generados con el desarrollo incompleto de trámites urbanísticos en los años 70 y 80.

Personas que son desahuciadas de sus viviendas por el impago de las hipotecas; edificios vacíos sin vender; estructuras inacabadas y constructoras inmovilizadas; noticias incomprensibles sobre la calificación internacional de los bancos y cajas de ahorro españolas, y sobre la cotización de la deuda española; amenazas de estancamiento económico cada vez más desalentadoras…

La reforma de los gobiernos locales en España
Authors: Castillo Blanco Federico A.
Published: March 2022

Tras sucesivos anteproyectos, elaborados uno tras otro a lo largo de más de un año, en julio de 2013 el Gobierno de España aprobó finalmente un texto que abordaba la reforma parcial del régimen local español bajo la denominación de Ley de Racionalización y Sostenibilidad de la Administración Local. El debate, como podía imaginarse, estuvo servido desde el principio. Y, ciertamente, el texto finalmente aprobado, la Ley 27/2013, de 27 de diciembre, aunque incorpora importantes medidas especialmente desde la lógica de la sostenibilidad financiera de las haciendas locales, dista mucho en el fondo y en la forma de los primeros borradores conocidos. Y desde luego dista aún más de haber afrontado con solvencia los retos que la planta local española presenta y que, a diferencia de otros países europeos (Grecia y Portugal significativamente) no ha transitado por la reducción del número de entidades locales.

Authors: Flores-De Jesús Victoria , García-Salazar José Alberto , Matus-Gardea Jaime Arturo , Almeraya-Quintero Silvia Xóchitl
Published: March 2022

Objetivo: medir los efectos de la politica de precios de garantia en la producción, el consumo y el saldo de comercio de frijol en la región de los Valles Centrales de Oaxaca. Metodología: se usó un modelo programación de precios endógenos que maximiza el excedente económico en el mercado de frijol en los Valles Centrales, se usó información promedio del periodo 2017-2019. Resultados: con la política de precios de garantía la producción aumentaría en 13.0 % y el consumo disminuiría 3.5 %, respecto a los niveles observados en el año base. Dichos cambios disminuirían el saldo de comercio de 6.3 a 5.5 miles de toneladas. Los cambios anteriores determinarían un aumento de 27.6 % en el excedente al productor y una contracción en el excedente al consumidor en 6.9 %, respecto al nivel observado en el año base. Limitaciones: las elasticidades utilizadas corresponden al mercado nacional de frijol. Conclusiones: la política de precios de garantía tiene un efecto positivo en la producción y el bienestar del productor, y un efecto negativo en el consumo y bienestar del consumidor. El aumento en la producción de frijol no sería suficiente para eliminar el déficit comercial; por lo tanto, se recomienda la implementación de otras políticas para aumentar la producción de la leguminosa.

Published: March 2022

This qualitative study is particularly focused on the North Sumatera context; it investigates the dynamics of ethnic and national identities of Bataknese youths in the defining themselves as an Indonesian. Thirty-one individuals (six local figures and 25 Bataknese youths) participated in the study. The results illustrated the strengthening process of ethnic identity through exploring family and environmental common practices. The strengthening of ethnic identity was also found to occur in concurrent with the strengthening of national identity, as manifested in the participants’ willingness to maintain harmony in their society. The study concludes that the strengthening of ethnic identity positively shapes one’s national identity. Student participants and local figures expressed concern about the sustainability of cultural cultivation which is necessary to shape ethnic identity among young Bataknese. The study recommends a Batak kinship model known as dalihan na tolu, in which many families with different tasks and roles, flexibly manage differences to strengthen national identity based on the philosophy of Bhinneka Tunggal Ika.

Authors: Erdem Hüseyin , Okuyucu İbrahim Cihangir
Published: March 2022

The aim of this study was to determine the relationships of udder surface temperature (UST) with milk components, and somatic cell count (SCC) in dairy cows during the hot season. The study was carried out with 115 lactating dairy cows (Holstein, Simmental, and Holstein × Simmental) at a private dairy farm in Samsun, Turkey, with monthly visits. The UST was measured from the udder surface before cleaning and milking. At the same time, a portable cell counter and an automatic milk analyzer were used to determine the components and the SCC of the raw milk. The UST values of the cows changed significantly. Increased UST had an adverse effect on milk solids-non-fat (SNF), protein, lactose, and density levels. LogSCC values of cow groups with UST ≤35.0°C, 35.1-36.0°C, >36.0°C were found to be 4.475±0.0803, 4.774±0.1244, and 4.981±0.1491 respectively. The UST negatively correlated with SNF, protein, lactose, density, and freezing point, but positively correlated with LogSCC. As a result, performing UST measurements before milking may be beneficial to monitor udder health and to obtain high quality milk.
Effects of PGPR, AMF and Trichoderma Applications on Adaptation Abilities to Different Biotic and Abiotic Conditions in Medicinal and Aromatic Plants
Authors: Şirin Ebru , Ertürk Yaşar , Kazankaya Ahmet
Published: March 2022

Medicinal and aromatic plants are valuable sources of herbal products worldwide due to their secondary metabolite content, high antioxidant activities and many other biological activities. As a result of the developing technology, the demand for natural active substances obtained from plants has increased. For use, plants collected from nature do not have the desired quality standards. For this reason, sustainability can be achieved by using microbial inoculants as well as many biotechnological and molecular approaches such as micro propagation, synthetic seed technology to increase the yield and quality standards of medicinal and aromatic plants. Thanks to microbial inoculants, yield increase can be realized and at the same time, product quality can be contributed due to increased soil quality. In this review, it was aimed to evaluate the important roles of plant growth promoting rhizobacteria (PGPR), Arbiscular mycorrhizal fungi and Trichoderma inoculants in increasing productivity, nutrient uptake and resistance of medicinal and aromatic plants to environmental stresses in the light of literature. In this review, the variation in the resistance of plants to environmental stresses is summarized by evaluating the ultimate effects of microbial inoculants alone and in combination. In addition, it has been added to the evaluation in studies to prevent the decrease of secondary metabolite content formed under environmental stress conditions in medicinal and aromatic plants by microorganisms.

A total of 140 fish in 14 groups were used in the experiment. The experiment was designed as in two different periods (acute and chronic) and 7 different dose groups (control, vehicle, V. vinifera seed extract 5 ppm, V. vinifera seed extract 10 ppm, Cd 20 ppb, V. vinifera seed extract 5ppm + Cd 20 ppb and V. vinifera seed extract 10 ppm + Cd 20 ppb). At the end of the experiment, the gill and liver tissues dissected from the fish were fixed, dehydrated, cleared, and paraffin impregnated. Appropriately sized blocks were prepared from the tissues, sections of 5-7 µm thickness were taken and covered by staining with hematoxylin-eosin. Stained preparations were examined under a light microscope and photographed. It was determined that all dose groups in the acute period and control groups were not different histopathological. It was determined that the histopathological damage caused by the cadmium group in the subchronic period and tissue damage were reduced in the dose groups with cadmium added with V. vinifera seed extract. As a result of the study, it was concluded that V. vinifera seed extract could have a therapeutic effect on the gill and liver tissues of carp exposed to cadmium.

The identification of plants in which the bees forage is key in establishing bee farms and increasing honey production. In this study pollen analysis of honey samples from the southeastern part of Nigeria was carried out to ascertain their floral sources and ecological origin. The honey samples were acetolyzed and microscopically studied to determine the pollen types. A total of seventy-one pollen types belonging to forty-one families of plants were identified. The honey samples were dominated by pollen grains from the families of Arecaceae, Euphorbiaceae, Myrtaceae, Irvigiaceae, Fabaceae, Combretaceae/Melastomataceae, and phyllanthaceae. Some of the dominant pollen grain identified include Elaeis guineensis, Alchornea cordifolia, Hymenocardia acida, Ocimum gratissimum, Syzygium guineense, Nauclea latifolia and Afzelia africana. Out of the six samples studied Njikoka sample was monofloral having Mimosa pigra as predominant pollen while Ayamelum, Ekwusigo, Nsukka, Ezeagu, and Udenu samples are multifloral containing Elaeis guineensis, Phyllanthus sp., Piliostigma reticulatum, Irvingia sp., Alchornea cordifolia, and Lannea sp. as major secondary pollen. All the samples analyzed have Elaeis guineensis in common except Ezeagu, indicating that these plants are present in all five locations. These results can also be used as a tool in the geographical identification of Southeastern Nigeria honey from other geopolitical zones.

The susceptibility of the newest and most used strawberry cultivars to the Spotted Wing Drosophila (SWD) in southwestern Spain was evaluated. Sixteen strawberry cultivarswere selected (‘Calderón’, ‘Calinda’, ‘Charlene’, ‘Flaminia’, ‘Flavia’, ‘Fortuna’, ‘Marisol’,‘Marquis’, ‘Melissa’, ‘Palmeritas’, ‘Petaluma’, ‘Plared0955’, ‘Primoris’, ‘Rábida’, ‘Rociera’and ‘Sabrina’) and no-choice tests were carried out under laboratory conditions. In addition, fruit weight, fruit firmness, °Brix, pH, protein content and total phenolic content were recorded in order to assess what influence these variables had on SWD infestation. The sixteen strawberry cultivars tested in this study were susceptible to SWD, although significant differences have been found among them. The mean number of emerged adults in ‘Calderon’ and ‘Plared0955’ were significantly higher than in the other tested cultivars. Significant differences in developmental time were also detected among these cultivars and both sexes but these were unrelated to the level of infestation. No correlation between fruit quality and chemical traits and infestation parameters was found. Our results detected significant differences in the susceptibility of strawberry cultivars in southwestern Spain to SWD; these may help to design IPM programs and to make recommendations for strawberry production, one of the most important crops in southern Europe.

The nanosatellite is a satellite with a weight of less than 10kg and an orbital height of 500km. Telkom University through Nano Satellite Laboratory is researching for many payloads on a nanosatellite. One of the nanosatellite payloads is Automatic Dependence Surveillance-Broadcast (ADS-B), an aircraft data transmission broadcast. The long-distance deliveries and space environmental disturbances can cause weak received signals. Therefore a Low Noise Amplifier (LNA) is needed to enhance the signal-to-noise ratio (SNR) of a received signal. This paper has successfully designed and prototyped a single-stage LNA with a gain of 12.7dB and it enhances coverage of ADS-B from 180 to 358km

Manufacturing process was important in the development of antenna technology in order to obtain the antenna optimal performance. One of the approaches to increase the antenna performance was to use a natural dielectric material. In the study, a waveguide antenna was designed by inserting a natural dielectric material, a FR-4-Epoxy (? = 4,3 in the simulator) into a waveguide with a width of 72 mm, a height of 34 mm, and a length of 50 mm. The properties of the mode waveguide antenna were modified by slightly varying the position of the dielectric material and adding an initial thickness of 1.6 mm. The excitation of the waveguide was configured using mode. On the simulation shows that the best performance of the waveguide antenna was obtained when the dielectric position is 2 mm from the connector and thickness 3,2 mm. The simulation also generates the parameter of -22,8 dB with gain and directivity was 5,77 and 1,799 respectively at a frequency 3 of GHz while from measurement the frequency was shifted at 3,15 GHz with -23,05 Db. The gain and directivity were not measured in this research due to the limitations of the owned measuring tools and the difficulty of accessing other facilities due to the covid-19 pandemic.
Foreign experience of penalization of economic crimes
Authors: Moskaeva Nadezhda Nikolaevna
Published: March 2022

The author focuses on the reforms of criminal legislation in Russia, which were aimed at the humanization of criminal responsibility, and aggravate the problem of peculiarities of economic crimes penalization. The creation of effective criminal and legal provisions aimed at the prevention of economic crimes is impossible based only on the study of national experience in this field. The latter requires a system analysis of the existing legal provisions aimed at the prevention of economic crimes in foreign legislation. The author studies criminal legislation of some foreign countries regarding the imposition of punishment for economic crimes. The authors offer ways to formalize punishment for criminal crimes in Russia. The authors arrive at the conclusion that particular provisions of the Criminal Code of Russia testify that penalization performed, unfortunately, is characterized by unsystematic character, groundlessness and mutual incoordination of punishment imposed for particular economic crimes. One of the ways of development of legal regulation of rules courts are guided by when imposing punishment, is the study of strengths and weaknesses of corresponding legal regulations in foreign countries. Based on the analysis of legal regulation and practice of imposition of punishment for economic crimes in foreign countries, the author articulates the position about the advisability of introducing a model of limited formalization of punishment in Russia. In this respect, the suggested formalized mechanism should be introduced gradually and holistically, and should be accompanied by critical interpretation of foreign experience.
On sectoral affiliation of legal relations in the field of public compulsory insurance of particular categories of public servants (theoretical issues)
Authors: Mamatkazin Il'ya Robertovich
Published: March 2022

The research subject is the system of social protection of law enforcement officers which includes various types of assurance depending on a particular situation. One of the types of assurance is public compulsory insurance of particular categories of public servants including internal affairs officers. Controversial issues appear in legal practice related to sectoral affiliation of legal relations in this sphere of insurance since legal relations are based on agreements (contracts). It influences the level of safety of internal affairs officers and defines the order of exercise of their right to insurance. The analysis of decisions of the Constitutional Court of Russia demonstrates that in this case it is not advised to assign paramount importance to agreement-based way of regulation, and arrive at the conclusion about the civil nature of these relations. The Constitutional Court has detected the presence of public obligation of the state underlying these relations and changing its nature. Besides, according to its functions, public compulsory insurance is in many respects similar to compulsory social insurance. Based on this fact, it’s possible to conclude that in its core, public social insurance corresponds with social assurance methods of insurance.

Современные системы оповещения и управления эвакуацией людей при пожаре способны реализовывать разные варианты оповещения (с задержкой начала эвакуации) и маршрутизации разных групп людей, что позволяет снизить плотность их потоков и вероятность образования критичных скоплений на путях эвакуации. Для практической реализации потенциальных технических возможностей этих систем требуются алгоритмы оповещения и эвакуации в соответствии с местоположением очага пожара, динамикой развития горения, характерными параметрами объекта и эвакуирующихся людей. Генерация таких алгоритмов возможна на основе информации о текущих значениях и динамики нарастания опасных факторов пожара в помещениях и на путях эвакуации. Необходимая информация может быть получена в результате численных исследований с применением программных средств, реализующих математические модели тепломассообменных и газодинамических процессов, а также процессов движения потоков эвакуирующихся людей при пожаре. Представлен один из примеров алгоритмов оповещения и эвакуации людей для здания образовательного учреждения. Расчётные данные позволяют спрогнозировать и оценить принципиальную возможность безопасной эвакуации людей при пожаре и предложить объёмно-планировочные, технические и организационные решения и мероприятия для её успешного осуществления.
