The COVID-19 infection caused by the new coronavirus SARS-CoV-2 has become the real pandemic. Children account for 1–6% of all diagnosed COVID-19 cases. Generally, children have mild disease in comparison to adults, and their mortality rates are extremely low. Despite the fact that all the main efforts of the medical and political community are now focused on preventing the pandemic spread and organizing medical care for patients with moderate and severe COVID-19 course, we still have to remember to implement adequate help for patients with chronic diseases, especially for children with allergic diseases. The pandemic period coincided with natural weather period of dusting of causative plants, that led to annual escalation of both allergic rhinitis and asthma in patient group with specific sensitization to tree pollen. Leading experts of allergology (adapting to modern conditions) have created key guidelines on management of children with allergic diseases during the COVID-19 pandemic. These guidelines are based on the data and results from the Union of Pediatricians of Russia, Russian Association of Allergologists and Clinical Immunologists, European Academy of Allergy and Clinical Immunology (EAACI), European Respiratory Society (ERS), American Thoracic Society (ATS), Global Strategy for Asthma Management (GINA), Initiative on Allergic Rhinitis and its Impact on Asthma (ARIA/MACVIA).

Saponins are an important group of plant secondary metabolites that are widely distributed throughout the plant kingdom. These biomolecules can be divided into two main classes represented by triterpenoid and steroid glycosides whose structure varies according to the number of sugar units attached in different positions. Despite saponins have been historically considered as anti-nutritional factors, recent studies have indicated that some saponin stereoisomers may show a number of pharmacological activities, such as anti-tumor, antioxidative, anti-inflammatory, antidiabetic, and neuro-protective activities. Nerveless, more attention in studying this group is necessary due to the fact that many active mechanisms are not fully elucidated. To have a systematic overview of saponin compounds, this review will describe the main aspects related to their structure, bioactivities and potential applications.

Published: June 2020

In this experiment we studied the influence of chemical fertilizers on physiological indices and the amount of protein in two soybean varieties, Atlas and Hodgson. Researches has been carried out between 2017-2019 at Didactic Station of BUASMV Timişoara with different doses of chemical fertilizers. Observations and measurements were made on plant physiology and yield characteristics. The process of accumulation of dry substances in different organs of the plant during the vegetation period is dependent to the effectiveness of fertilization. The dynamics of the total water content in the plant and especially its modification under the influence of chemical fertilizers is of interest for the appreciation of the process of formation of dry substances, respectively of agricultural harvest. In both varieties between the experimental and the control variant, significant differences appeared in all followed indicators, the most favorable variant being N45P63K45. Superior results were registered at Atlas, better adapted to the ecological conditions of the reference area. Fertilizers are decisive factors in the increase of yield and the quantity of protein, although this plant has the capacity to supply some of the necessary nitrogen with bacterial symbionts. High doses of phosphorus did not produce higher yields compared to moderate ones.

Published: June 2020

Lipid nanoparticles are getting a growing scientific and technological interest, worldwide. Either Solid Lipid Nanoparticles (SLNs), Nanostructured Lipid Carriers (NLCs), Lipid Drug Conjugates (LDCs) or Polymer-Lipid Nanoparticles (PLNs) have been produced and investigated last years, being reccomended as emerging carrier systems for many food and biomedical applications. An overview of the last publications, mainly since 2017 is presented, underlying the most important methods and techniques used for their preparation (e.g. high shear homogenization in hot and cold conditions, ultrasound assisted melt emulsification) as well techniques applied for measuring the size, calorimetric properties, zeta-potential, etc. Most relevant data related to the use of food-grade ingredients and designed lipid nanoparticles as delivery systems for organic and inorganic bioactive molecules in food or packaging’s are presented. The major reason for this trend in food science is the aim to overcome problems associated with the low bioavailability of many lipophilic bioactive compounds which are claimed to bring benefits to human health (carotenoid or anthocyanin pigments, sterols, vitamins). Finally, the recent applications of different formulas of lipid nanoparticles as drug carriers for in vitro experiments or for in vivo therapy (oral, parenteral or transdermal formulas) are presented.

Published: June 2020

A field experiment was conducted in Southern Greece to assess Normalized Difference Vegetation Index (NDVI) and Red-Edge Normalized Difference Vegetation Index (NDRE) in estimating Camelina’s crop growth and yield parameters under different tillage systems (conventional and minimum tillage) and organic fertilization types (compost, vermicompost and untreated control). A proximal canopy sensor was used to measure the aforementioned Spectral Vegetation Indices (SVIs) at different days after sowing (DAS). Camelina presented the highest values of NDVI and NDRE under compost fertilization (0.63 and 0.22 accordingly) and minimum tillage system (0.50 and 0.18 accordingly). Additionally, the highest correlations between the measured crop parameters and NDVI, NDRE were achieved at leaf development to early flowering stage. Moreover, NDRE presented the highest correlation with seed yield (R2=0.60, p<0.05) and thus it is suggested for estimating Camelina’s productivity instead of NDVI. Finally, further research is needed for adopting the use of remote sensing technologies on predicting Camelina’s crop growth and yield.

Published: June 2020

The research subject of this paper was conducted in Satu Mare County, Romania, where three strawberry cultivars have been studied, namely ‘Alba’, ‘Viktoriana’ and ‘Camarosa’, on two different types of mulch (black mulch and straw mulch). Observations, measurements, and determinations have been made regarding the growing vigor of the bushes, productivity and fruit quality. The productivity analysis favored the ‘Camarosa’ cultivar as highly productive, which is why this cultivar can be proposed for use in plantations. The different mulch types have significantly influenced the weight of the fruit quality, the highest weight being obtained on the black foil substrate. As for the fruit quality, the ‘Camarosa’ cultivar, which is very valuable from the qualitative point of view, obtained the highest average value of the sugar content measurements, precisely (8.7°Brix).

Published: June 2020

The main purpose of the present paper is to highlight the most important non-wood forest products (NWFPs) from Sălaj County. For this purpose, a set of 19 criteria was taken into consideration and the analytic hierarchy process was applied to establish criteria weights. Subsequently, the method was tested by using Expert Choice software. The selected NWFPs were: honey fungus [Armillaria mellea (Vahl) P.Kumm.], parasol mushroom [Macrolepiota procera (Scop.) Singer], acorns, Tilia flowers, wild strawberry (Fragaria vesca L.), St John’s wort (Hypericum perforatum L.), European roe deer (Capreolus capreolus L.) and European pine marten (Martes martes L.). The two NWFPs with the highest potential were European roe deer and honey fungus, while the less important ones were Tilia flowers and St John’s wort. Sălaj County has great potential, diversity and distribution of the NWFPs, but this sector is underdeveloped and disorganized. This approach provides forest managers with information to develop further NWFP management strategies.

Published: June 2020

Grapevine trunk diseases (GTD) are among the most important diseases reported in vineyards in central Transylvania. On average, up to 5% of the vineyards are affected by the GTD although there are also vineyards where the incidence of the attack exceeds 15%. Recent studies show that the importance of pathogens in wood is so great that they are considered limiting factors that affect the stability of the world’s vineyards. The main objective of this study is to develop new sustainable management alternatives for the GTD control. For this purpose, an agroecological variant including prophylactic and cultural measures and two treatments with biofungicides based on: Trichoderma atroviride strain 8, Trichoderma atroviride strain B11 and Trichoderma harzianum, were tested. The frequency of the attack of the main four GTD diseases (Esca complex, Phomopsis dieback, Eutypa dieback and Crown gall) on the SCDVV Blaj homologated grapevine varieties, ‘Astra’, ‘Amurg’, ‘Brumariu’, ‘Blasius’ ‘Radames’, ‘Rubin’ and ‘Selena’, was assessed showing that these had a lower frequency of the symptoms compared with the widely cultivated variety ‘Feteasca regala’. Also the effect of training system (Classical versus semi-high Guyot) on GTD is presented. The classical system had decreased the frequency of crown gall and Phomopsis dieback, and the semi-high Guyot system had decreased Eutypa dieback’s frequency, indicating that the training system is an important tool of the agroecological system in maintaing the health of grapevine. Biofungicides tested help reduce the symptoms of GTD, but not enough to help reduce the premature death of grapevine.

Published: June 2020

Helichrysum amorginum is a perennial shrub, endemic on the Greek island of Amorgos and used for medicinal, cosmetic and ornamental purposes. Information concerning germination behavior and seedling survival is considered essential for the establishment and cultivation of wild species. The objective of this study was to investigate the effect of temperature and light on germination of Helichrysum amorginum seeds. A set of experiments was conducted under completely randomized design with four replications of 200 seeds at three different suboptimal germination temperatures (15, 20 and 25°C) in light and dark conditions for 10 days. Seed material was collected from two different fields of the island (Aegiali and Katapola). The germination performance was evaluated by final germination percentage and mean germination time. The effect of temperature on seed germination percentage and mean germination time was significant in all cases. The presence of light enhanced germination, especially at the optimum temperature of 20°C. In most cases the mean germination time increased at the lower temperature of 15°C. Seeds from Aegiali exhibited higher germination ability than the seed lot from Katapola. Knowledge of seed germination behaviour is of major importance in order to establish effective protocols for seed propagation in Helichrysum amorginum.

Cadmium’s mechanism of toxicity is manifested by its fixation in mitochondria, inhibition of cellular respiration and oxidative phosphorylation. Vitamin E could act as a protective factor against the harmful effect of Cadmium intoxication. The experimental animals were randomly allocated into 3 experimental groups of 6 rats. The collected blood samples were used to determine hematocrit, hemoglobin concentration, blood erythrocyte count and leukocyte count. The following derived red blood cell parameters were calculated in parallel according to the standard methodology. Between groups 1 and 2 there are no significant differences, a sign that vitamin E exerts an effective protective role. We found a significant increase in the white blood cell count and the neutrophil count in group 3 compared to group 1. Between groups 1 and 2 there are no significant differences, a sign that vitamin E has annihilated the cadmium-induced specific effect. In the case of cadmium poisoned rats, we found a decrease in the number of red blood cells, the hematocrit and the hemoglobin level, but also a significant increase in the number of white blood cells. If rats were treated with cadmium and vitamin E, there were not significant differences from the control group.

Bite wounds, human and animal origin, can lead to significant complications if appropriate therapy is not undertaken timeously. The major risk of these aggressions is given by the possibility of systemic propagation of the bacteria involved in the wound and the appearance of complications such as osteomyelitis, septic arthritis, bacterial endocarditis, etc. The identification of pathogenic germs and antibiotic sensitivity test were the key points for a specific therapy that could prevent the spread of infection in the deep tissues. Twenty five biological samples collected from various wounds produced by dogs and cats bites over the veterinary personnel during the medical evaluated. Various aerobic pathogenic and conditional pathogenic bacteria (Staphylococcus aureus, Staphylococcus pseudo intermedius, Staphylococcus intermedius, Staphylococcus epidermidis, Staphylococcus hominis, Staphylococcus xylosus, Staphylococcus warneri, Micrococcus roseus, Streptococcus sp. gr.B, Streptococcus sp. gr.F, Streptococcus sp. gr.G, Enterococcus faecalis, Enterococcus faecium, Trueperella pyogenes, Corynebacterium sp., Bacillus cereus, Pasteurella multocida, Pasteurella canis, Mannheimia haemolitica, Escherichia coli, Pseudomonas aeruginosa, Actinobacillus sp., Neisseria sp) and anaerobic bacteria (Clostridium perfringens, Bacteroides sp.) were isolated. The bacterial drug sensitivity was fluctuating, observing the variations influenced by the natural and acquired resistance of the tested bacterial species. The wounds produced by the bites of dogs and cats have aerobic and anaerobic polymicrobial etiology.

Authors: Khan Qaiser uz Zaman , Ahmad Afaq , Mehboob Saqib , Iqbal Muhammad
Published: June 2020

Lateral load tests were conducted, for four scaled-down (1 : 4) bridge piers made of low-strength concrete, with two of them having 12.4 MPa up to the damage state, and the other two having 16.5 MPa. These damaged bridge piers were then retrofitted with carbon-fibre-reinforced polymer (CFRP) wrapping in single and double layers, and tested again under the same cyclic quasi-static loading. A numerical investigation of these bridge piers was carried out, and the results of the energy dissipation are presented. The numerical results were in good agreement with the experimental results and reveal that, with increasing the number of layers of CFRP on a bridge, there is an increased amount of energy dissipation and hence ductility of the pier. The CFRP retrofitted piers not only recover their original strength, but the lateral load capacity is also increased considerably.

Published: June 2020

La familia es el contexto que por excelencia cumple un rol básico en torno al óptimo desarrollo del niño, si bien es sabido que la escuela contribuye sobremanera en este sentido. De la repercusión que, más allá de lo académico, puede tener la estancia de sus hijos en los centros educativos, subyace la relevancia y preocupación que padres y madres le dan al clima escolar de convivencia, pues de no ser el adecuado puede derivar en situaciones de violencia con múltiples consecuencias negativas para el alumnado. Por una y otra razón, este trabajo persigue conocer la percepción que el alumnado, en concreto de Educación Primaria, tiene sobre conductas violentas presenciadas y sufridas y el tipo de acciones que lleva a cabo en ambos casos, así como también la visión de sus familias acerca de este clima. Para ello, han participado 200 alumnos (52% niñas y 48% niños) de 4º , 5º y 6º de Educación Primaria y 92 madres y padres (73.9% mujeres y 26.1% hombres). Generalmente, lo recabado es positivo, pues tanto la presencia y la vivencia como la pasividad ante este tipo de episodios es baja por parte del alumnado y la familia no duda del buen hacer del centro y de sus docentes al respecto. Aun así, no debe olvidarse la parte de la población que, aunque reducida, hace una valoración más negativa. En cuanto a este tema, los programas de parentalidad positiva y aquellos destinados a incrementar la comunicación familia-centro y la participación familiar pueden ser una herramienta de gran utilidad.

Published: June 2020

El envejecimiento de la población en España es una cuestión que no solamente atañe a la salud de la población y a Sanidad, sino que tiene importantes repercusiones en la economía, estructura familiar, sostenibilidad del sistema de pensiones, etc. Supone un elevado gasto sanitario, como ejemplo: el 52% del gasto de Atención Especializada se dedica a mayores de 65 años y los mayores de 70 años son los responsables del 40% del total del gasto sanitario. Los datos anteriormente expuestos denotan que el sistema sanitario no ha sabido adaptarse a la nueva situación social, aumentando el edadismo y responsabilidad de la sostenibilidad del sistema a la población anciana. Los biomarcadores de depósito amiloide y de neurodegeneración (obtenidos del líquido cefalorraquídeo: péptido Aß1-42 ylas proteínas Tau totaly Tau fosforilada), o bien por técnicas de neuroimagen (resonancia magnética(RM) o tomografía poremisión de positrones(PET con18F-fluorodesoxiglucosa PET-FDG). Los biomarcadores en sangre periférica aún no están estandarizados para el diagnóstico clínico. Por ello, la utilización de técnicas de imagen hiperespectral para la determinación de biomarcadores, así como la aplicación de estas técnicas en la clínica, favorecerán tanto el diagnóstico como el tratamiento de los pacientes con DTA.

Published: June 2020

Si bien las personas con discapacidad intelectual experimentan la misma necesidad de intimidad que el resto, una serie de barreras sociales impiden la expresión de su sexualidad alentando a que se les perciba como seres asexuales. Por ello, durante mucho tiempo las voces de las personas con discapacidad no han sido escuchadas, lo que conlleva que actualmente exista una escasez de herramientas de evaluación para explorar los diferentes aspectos de la sexualidad de este colectivo teniendo en cuenta sus limitaciones en lectoescritura y comprensión. El objetivo de este estudio es la elaboración de una entrevista semiestructurada fiable y válida que contemple las características de las personas con discapacidad intelectual y posibilite la evaluación de su conducta sexual. Este instrumento, que ha sido administrado a 360 personas con discapacidad intelectual leve o moderada de entre 19 y 55 años, está formado por 34 ítems (26 de respuesta cerrada y 8 de respuesta abierta) agrupados en 4 dimensiones: comportamientos sexuales (19 ítems), conductas preventivas (3 ítems), información recibida sobre sexualidad (6 ítems) y experiencias de abuso sexual (6 ítems). En el proceso de construcción-validación de esta entrevista se ha visto implicado un grupo de expertos que analizaron su formato y contenido en diferentes fases. La versión final cuenta con una fiabilidad aceptable (✔ = .73).

ABSTRAKTerak II timah merupakan produk hasil samping dari peleburan timah tahap kedua. Terak II timah ini mengandung unsur bernilai ekonomi tinggi berupa unsur radioaktif (uranium dan torium) dan logam tanah jarang (rare earth element). Unsur-unsur tersebut dapat dimanfaatkan apabila telah terpisah satu dengan lainnya. Proses pemisahan unsur radioaktif dan unsur logam tanah jarang telah dilakukan dengan metode pelindian asam sulfat. Hasil proses ini adalah endapan yang mengandung logam tanah jarang dan filtrat yang mengandung unsur radioaktif berupa uranium dan torium sulfat. Penelitian terkait pemisahan uranium dan torium hasil pengolahan terak II timah hanya sedikit dipublikasikan. Paper ini bertujuan untuk mengetahui efektifitas proses pemisahan uranium dan torium dengan metode solvent extraction menggunakan trioctylamine (TOA). Proses solvent extraction dilakukan dengan memvariasikan konsentrasi TOA yang digunakan, perbandingan fase aqueous dan fase organik (A/O) dan variasi waktu ekstraksi. Pada penelitian ini diperoleh kondisi optimum proses yaitu konsentrasi TOA 4%, perbandingan A/O 1 : 1, dan waktu pencampuran aqueous dan organik selama 2 menit. Pada kondisi ini uranium dan torium yang terekstrak masing-masing sebanyak 67% dan 0,84%. ABSTRACTTin slag II is a by-product of the second stage of tin smelting. The tin slag II contains high economic value elements in the form of radioactive elements (uranium and thorium) and rare earth elements. These elements can be utilized if they are separated from each other. The process of separating radioactive elements and rare earth elements has been carried out by leaching sulfuric acid method. The results of this process are residue containing rare earth elements and filtrates containing radioactive elements in the form of uranium and thorium sulfate. Research related to the separation of uranium and thorium sulfate in tin slag processing is only slightly published. This paper aims to determine the effectiveness of the uranium and thorium separating process by the solvent extraction method using trioctylamine (TOA). The solvent extraction process is carried out by varying the concentration of TOA used, comparison of the aqueous and organic phase (A/O) and variations in extraction time. In this study, the optimum conditions for the process were obtained at 4% of TOA concentration, 1 : 1 of A/O ratio, and mixing time of aqueous and organic phase for 2 minutes. In this condition, uranium and thorium which extracted were 67% and 0.84% respectively.

ABSTRAKMineralisasi uranium (U) di Sektor Lembah Hitam pada batuan metalanau dan metapelit sekistosan berasosiasi dengan mineral pirit, pirhotit, magnetit, molibdenit, turmalin, dan kuarsa. Kehadiran mineral U ditandai dengan nilai radiometri batuan yang mencapai 15.000 c/s. Estimasi cepat kadar U adalah menggunakan perhitungan gamma ray hasil logging gross-count gamma lubang bor LH-01. Penelitian ini bertujuan untuk mendapatkan validitas dan reliabilitas data estimasi kadar U. Hasil estimasi kadar U logging disebandingkan dengan analisis geokimia untuk mendapatkan faktor koreksi (Fk). Analisis geokimia menggunakan metode X-Ray Fluorescence (XRF) pada sampel batuan terpilih di interval kedalaman yang mewakili batuan dan mineralisasi di lubang tersebut. Estimasi kadar U di kedalaman 8,80–9,81 m berdasarkan gross-count gamma ray menunjukkan nilai kadar 456 ppm eU, sementara analisis XRF menunjukkan rerata kadar 177 ppm U. Nilai faktor koreksi (Fk) yang didapatkan dari estimasi kadar di kedalaman 8,80–9,81 m adalah 0,388. Nilai tersebut menunjukkan validitas dan reliabilitas data estimasi yang digunakan rendah. Kesebandingan estimasi kadar U dipengaruhi oleh beberapa faktor, antara lain: sistem logging gross-count gamma ray, ketidaksetimbangan uranium, ukuran sampel, dan unsur radioaktif lainnya. Untuk meningkatkan validitas dan reliabilitas data estimasi, maka diperlukan penambahan sampel analisis XRF dengan mempertimbangkan lingkar dan interval kedalaman lubang bor. ABSTRACTUranium (U) mineralisation in Lembah Hitam Sector in metasilt and schistossic metapellite rocks was assosiated with pyrite, pyrhotite, magnetite, molibdenite, tourmaline, and quartz minerals. The existence of U mineral was marked from its radiometric value reaching 15,000 c/s. The faster way to estimate U grade is using gamma-ray values calculation from gross-count gamma logging at borehole LH-01. The research is aimed to obtain the validity and reliablility of U grade estimating data. The logging estimation result then compared with geochemical analysis to obtain the correction factor (Fk). Geochemical analysis is using X-Ray Fluorescence (XRF) method on selected rock samples represent rock and mineralisastion depth interval inside the borehole. The result of uranium grade estimation using gross-count gamma ray calculation in depth 8.80–9.81 m is 456 eU while based on XRF analysis, the result is 177 ppm U. The correction factor (Fk), obtained from grade estimation at 8.80–9.81 m depth is 0.388. The value indicates that the validity and reliability estimation data is low. Ratio of U grade estimation depends on some factors, like gross-count gamma ray logging system; uranium disequilibrium, sampels size; and other radioactive elements. In order to increase the validity and reliability estimation data, XRF analysis samples should be added by considering the borhole diameter and depth interval.

316L stainless steel is widely used as an orthopedic implant due to its high corrosion resistance and biocompatibility, but the weakness of these materials is low hardness and high wear. The surface must be modified to improve the material. For the purpose, a titanium nitride (TiN) thin film was deposited on the surface of SS 316L using DC sputtering technique. The sputtering process was carried out for various of a gas mixture of argon (Ar) and nitrogen (N2) such as  90 Ar: 10N2, 80 Ar: 20 N2, 70 Ar: N2, and 60 Ar: 40 N2, while the other parameters kept constant.  The objective of the gas mixture variation is to find out the optimum condition of ratio Ar: N2 gas mixture with the highest hardness and lowest wear resistance. From experiment done it’s found that the highest hardness in order of 232.02 VHN, while before being coated the hardness is 133.61 VHN, or there is an increasing hardness by factor 1.73, while the wear resistance reduces from  11.6 × 10-8 mm2/kg to 1.17 × 10-8 mm2/kg or there is reducing in wear resistance by factor 9.9.  The optimum conditions were achieved at Ar: N2 ratio = 70:30. From XRD analysis, it can be concluded that the crystal structure of TiN thin film is cubic with the peaks (111), (200), (202), (311) and (222). From cross-section microstructure analysis using Scanning Microscope Electron (SEM), it’s found the thickness of the thin film is 744 nm.

The reactivity value of the Bandung TRIGA 2000 reactor core has decreased over time, so the power generated by the reactor is also getting smaller, despite the control rod position is fully withdrawn. Therefore, it is necessary to reshuffle and refuel the fuel element to increase the excess reactivity by considering the safety parameters, such as axial and radial power peaking factors, DNBR, dTsat, and temperature on the cladding and in the center of the fuel element. The analyzed reactor safety parameters are the number of fuel elements, which varied at 105, 110, and 115 elements, as well as power peaking factor, which varied at 1.55, 1.65, 1.75, 1.85, and 1.95. The calculations were done using MCNP and COOLOD-N2 programs. If DNBR ≈ 1.3 is determined as the safety limit for the operation of the Bandung TRIGA 2000 reactor, at PPF 1.95 (105, 110, and 115 fuel elements), it can be considered to operate the reactor at the power of 600-700 kW. However, at PPF of 1.75 (105, 110, and 115 fuel elements), the reactor can be operated at the power of 700-800 kW, and at PPF of 1.55 (105, 110, and 115 fuel elements), the reactor can be considered for operation at the power of 800-900 kW. The results of these calculations can be used for consideration in determining the operating limits of the Bandung TRIGA 2000 reactor.Keywords: TRIGA 2000, fuel element, power peaking factor, DNBR, boiling
