Published: June 2020

In this study we followed the way in which evolves the behaviour of some honeybee families (Apis mellifera carpathica, Linnaeus), maintained in vertical beehives (modified Dadant type), in conditions of stationary bee keeping, having in view the natural queen cell’s build rhythm after the second acacia tree harvest (Robinia pseudoacacia L.) in Jucu area of Cluj County. There were taken into observation 20 biological units with queen bees of different ages. It was monitored the development rhythm of natural queen cells, which are in attendance by the working bees, and to put into evidence the swarming instinct strength, so in bee keeping practice to be known and to be avoided the natural swarming. The determination of occupied surfaces with covered brood and larval was effected with the Netz framework. The aim of our study was to understand how the swarming in honeybees occurs. By detailed observation, we want to describe and to explain the behaviour of honeybees before the swarming process. The obtained results are quantified in absolute values and expressed graphically in relative values, but in the next three apicultural years (2020, 2021 and 2022), the experiment will be repeated for a variance analysis, which will provide a statistical assurance. We hope that these data will give contribution for the apicultural practice, keeping attention on queen bees’ importance during active season and on careful supervision on development rhythm of the honeybee units during the natural swarming.
Varroa Destructor and the Sustainability of Apis Mellifera - an Overview
Authors: GIURGIU Alexandru Ioan , MOISE Adela Ramona , DEZMIREAN Daniel Severus
Published: June 2020

Varroa destructor is a parasitic mite that represents a major global threat for the Western honeybee Apis mellifera. This parasite managed to switch from its natural host the Eastern honeybee, A. cerana, and within a few decades, it spread among A. mellifera populations around the world. Today beekeepers are using a variety of different acaricides to keep the parasite population under control. However, for many of these substances, the parasite evolved resistance asking for the development of novel compounds. Hence the treatment is less suited as a sustainable tool in honeybee health; consequently, other alternative options are needed, and breeding of Varroa resistant honeybees have been suggested as a more sustainable solution. Here we reviewed the successful efforts and the apicultural procedures needed to be implemented to achieve resistant honeybees. We also describe the underlying resistance mechanisms and discuss the benefits of breeding within regional populations, considering the biodiversity aspects of A. mellifera.

Published: June 2020

Soybeans are species of legume that has become one of the most widely consumed food in the world, because they are easy to cultivate and very beneficial for human health. The quality of the cultivated plants, including the content of toxic heavy metals depends to a large extent on the contaminants present in the soils in which they are grown and the method of fertilization. Through this research we aim to highlight the degree of accumulation of cadmium, chromium, cobalt, copper, nickel, lead and zinc in relation with the cultivated soybean genotype and fertilization. Three soy varieties (Cristina, Felix and Onix) were cultivated in an experimental field located at Cojocna Experimental Didactic Center of the University of Agricultural Sciences and Veterinary Medicine of Cluj-Napoca. The above-mentioned heavy metals were determined from the harvested mature soybean seeds using inductively coupled plasma-optical emission spectrometry, using an Avio 200 instrument. The obtained results demonstrated that the accumulation of heavy metals in soybean seeds is influenced by the cultivated genotype and fertilization; the Onix variety is more prone to the accumulation of heavy metals, while the highest values of the above listed metals were recorded in the case of fertilizing with „Fertitel”.

The effect of the reflection by a white agrotextile, in hemp cultivation, was evaluated on a greenhouse experiment during 2019. The experiments were laid out in a completely randomized design with two treatments (soil cover and control). The results indicated that the average temperature in the covered area section was 28.5ºC while in the uncovered area was 25.12ºC, during the experiment. Concerning height, higher plants up to 20 cm, were recorded on the covered area than the uncovered one. The highest specific leaf area (SLA) (58.39 cm2 g-1) was found on the covered area at 60 days after transplanting (DAT) compared to the uncovered area where a value of 50.4 cm2 g-1 was recorded. The absolute growth rate was higher during 20-60 DAT comparatively to control. The highest rate was observed about 50-60 DAT where it reached the value of 3.34 g day-1. Concerning root system, arbuscular mycorrhizal fungi (AMF) was only affected by the cover material. The number of inflorescences was not found to be affected by the cover material but the bud length and the cannabidiol (CBD) content were affected by the soil cover. The cannabinoids (CBD) content was 28.8% higher on covered area.

Published: June 2020

Non-woody forest products (NWFPs) represent an important forest resource which can be exploited, becoming in this way, an important economic role in human societies. In addition, NWFPs are used both in households and as commercial products for human well-being. Due to the fact that Romania has a wide variety of relief forms, numerous NWFPs can be found on her territory, the most important ones being the forest fruits. Their benefits come especially from their chemical composition, because of the richness in vitamins and antioxidant properties, being used in alimentation, medicine and the cosmetic industry. On the other hand, their importance is gained by the social and economic impacts, most of them being positive. The paper exposes the most representative forest fruits from Bistrita-Năsăud County which were analysed by using an analytical hierarchy process, being a multi-criteria method in decision making. Based on this process, forest fruits were classified by 19 well-established criteria.

Soil is a complex and dynamic factor that, needs to be studied, analyzed, known and understood. The spreading of soils in the territory is conditioned by the microrelief, lithology characteristics and the hydrographic network. This paper aims to establish the soil survey characteristics and soil evaluation of an agricultural land to be introduced into the national forest fund for afforestation.In order to achieve the proposed goals, in addition to the classical works, orthophotomaps were used. To establish an afforestation solution, the main site characteristics were determined on the field: altitude, exposure, slope, functional category. These characteristics have been associated with laboratory analyzes to determine soil type, with orthophotomaps measurements and weather data. Analyzing the collected data, the land was enclosed in the bioclimatic hilly region of Turkey oak stand (FD2), where the main species best suited is the Turkey oak, mixed with flowering ash, field maple and pear-tree.

Authors: PAPASTYLIANOU Panayiota , KOUSTA Angeliki
Published: June 2020

Water availability is one of the major limiting factors of cotton productivity. The soil application of superabsorbent polymers (SAPs) may increase water use efficiency, improve soil physical properties, enhance seed germination and emergence, crop growth and yield and reduce the irrigation requirements of plants. The objective of this study was to investigate the effect of Zeba®, a polymer based on corn starch, on seedling emergence and growth of cotton under water stress. A set of pot experiments was conducted under completely randomized design with four replications of 25 seeds. Treatments included application rates of 5, 10, 15, 20 kg/ha and an untreated control, all under three levels of irrigation (adequate, moderate and deficit). The emergence performance was evaluated by final emergence percentage and mean emergence time. Root and shoot growth were measured for length and weight. The application of Zeba® promoted seedling emergence (higher emergence percentage from 17.9 to 22.6% and lower mean emergence time from 36 to 46% compared to control). Higher values for root and shoot traits were observed under Z10 and Z15 rates regardless of irrigation treatments. The adoption of the proposed SAP could represent a promising solution and thus increase moisture conservation in cotton.

This study was carried out in order to identify the different parasites (ecto and mesoparasites) infesting the tortoise Testudo graeca graeca. For this, a population of 24 tortoises was studied from mid-March to May 2018, in the region of Aflou-Laghouat, within two sites: Djellel and Oued Sebgag. The turtles were captured at the time of their activity; sex, age, body weight, total length of the shell and body height were determined. A careful search for parasites has been carried out using various recommended techniques. A total of 126 Hyalomma aegyptium ticks were identified, with an overall prevalence of 71%, an average intensity of 7.4 and an abundance of 5 ticks per individual. The stool examination identified six mesoparasites, namely: Angusticaecum holopterum, Enterobius vermicularis, Strongylus sp, Nematodirus sp, Trichostrongylus sp, Fasciola hepatica. The sex of the host showed a significant influence on the parasitic infestation: the females were four times more infested than the males.

Published: June 2020

Headcut erosion is a very common process occurring at the head of rills, crop furrows and ephemeral gullies. A numerical model of the headcut flow was built to study the wall shear stress characteristics downstream of the scour hole, which is very important in headcut erosion prediction models. The calculated nappe parameters are very close to experimental data and/or equation results. The calculated flow field, velocity centreline of the free jet part and the locations of the maximum velocity in the scour hole are also close to the experimental data. It was found that the upstream flow rate and downstream water level can affect both the maximum value and the distribution of the wall shear stress. Taking into account the affecting factors and referencing the form of the existing relations on the maximum wall shear stress caused by the impinging jet, the relation of the maximum wall shear stress occurring downstream of the headcut is obtained. The wall shear stress distribution can be described by exponential functions. The new prediction equation of the maximum wall shear stress can be used in existing headcut erosion prediction models for calculating equilibrium scour hole depth or scour hole deepening rate.

Published: June 2020

Las actitudes hacia la sexualidad de las personas con discapacidad parecen haber evolucionado en positivo. No obstante, todavía existen creencias erróneas que ayudan a mantener una actitud negativa hacia la sexualidad de estas personas dificultando su desarrollo psicosexual. Este trabajo analiza las actitudes hacia las relaciones de pareja de personas con discapacidad que poseen sus familiares, profesionales y población general. En el estudio participaron 252 personas: 86 familiares, 80 profesionales y 86 personas de la población general. Los resultados muestran que en todos los casos los familiares presentan menor tolerancia hacia las relaciones de pareja mientras que los profesionales han sido el grupo más tolerante. Concretamente, se observan diferencias estadísticamente significativas entre los tres grupos en la actitud hacia las relaciones de pareja ya sea entre personas con discapacidad intelectual (M=33; DT=3,12 en familiares, M=71,09; DT=5,13 en profesionales y M=63,14; DT=20,87 en población general), sensorial (M=32,48; DT=3,49 en familiares, M=73,3; DT=4,06 en profesionales y M=70,79; DT=17,79 en población general) o física (M=34,32; DT=3,02 en familiares, M=80,82; DT=4,82 en profesionales y M=66,60; DT=21,15 en población general). Asimismo, los familiares muestran actitudes más desfavorables cuando las relaciones se establecen tanto entre parejas de distinto género (F=275,08; p=,000) como del mismo (F=319,92; p=,000), así como entre parejas de igual edad (F=424,79; p=,000) o diferente (F=273,1; p=,000). Estos datos remarcan la importancia de incluir módulos actitudinales en programas de educación afectivo-sexual dirigidos a los familiares puesto que permitiría no sólo mejorar la actitud de los padres sino también la que han podido aprender sus hijos favoreciendo así una adecuada expresión y desarrollo de su sexualidad.

Published: June 2020

La prevalencia de infecciones de transmisión sexual supone un problema grave de salud pública. La población joven se reconoce como la más afectada, pero no existe suficiente evidencia sobre algunos perfiles diferenciales. Esto, obstaculiza los esfuerzos preventivos, en particular, cuando la diversidad afectivo sexual sólo se aborda de manera categorial, clasificando entre heterosexuales, bisexuales y homosexuales. Por ello este trabajo explora las prevalencias de las ITS, así como las diferencias en la conducta preventiva primaria y secundaria según la orientación sexual, evaluada no de manera categorial sino según la escala Kinsey. 600 estudiantes universitarios (50% hombres y mujeres; 67,5% atraídos únicamente hacia el otro sexo) cumplimentaron, de manera online, voluntaria y anónima, el cuestionario Estilo de Vida y Salud (Giménez-García y Ballester-Arnal, 2017).Los resultados arrojan una prevalencia de ITS de 5,3%, concentrándose mayor frecuencia entre personas un poco más atraídas hacia el otro sexo (19%) y exclusivamente hacia el suyo (14,3%), con diferencias significativas (Chi 2=15,75; p= ,027). Sobre el uso sistemático del preservativo, el 52,8% lo reporta con parejas esporádicas y el 37,1% con estables, mostrándose diferencias en las últimas (Chi 2=17,69; p=,007). En ambas, las personas a las que les atrae un poco más su mismo sexo lo utilizan más (100% esporádica y 67,7% estable) frente a las que principalmente les atrae su sexo (33,3% esporádica y 0% estable). En la prueba de detección del VIH que reporta un 16,7%, existen diferencias significativas (Chi 2=16,86; p= ,018), siendo más frecuente entre personas atraídas únicamente (35,7%) o principalmente (28,6%) hacia su mismo sexo. Así, las mayores prevalencias parecen concentrarse entre personas un poco más atraídas por el otro sexo y únicamente el propio, siendo distintos los grupos de mayor riesgo según la conducta preventiva. En consecuencia, los esfuerzos preventivos deberían velar por un carácter inclusivo de todas las orientaciones del deseo sexual.

Numerosos estudios refieren la importancia del desarrollo psicológico durante la etapa perinatal. Conocer las creencias de los futuros maestros en torno a la educación perinatal puede ayudarnos a comprender la necesidad de ampliar la formación en este ámbito y revisar creencias basadas en experiencias personales y enseñanzas del entorno. El objetivo de este estudio es profundizar en las creencias de los alumnos de magisterio en relación a la importancia del desarrollo y la educación perinatal analizando el discurso escrito de 36 alumnos con una media de 20 años de edad a través de estudio cualitativo. Se formularon las siguientes preguntas relacionadas con el desarrollo perinatal durante una clase de la asignatura de Psicología del Desarrollo del Grado de Educación Primaria en Toledo: ¿se debe abrazar y besar al bebé o crees que es malcriarlo?, ¿por qué crees que se recomienda el piel con piel tras el nacimiento?, ¿quién crees que es la persona más importante para el bebé a nivel biológico, psicológico y social?, ¿qué consecuencias crees que tiene sentirse amado durante los primeros meses de vida?, ¿y no sentirse amado? Los alumnos contestaron por escrito de manera individual. La mayoría de los alumnos consideraron positivo abrazar y besar al bebé y se refirieron a la madre como la persona más importante para él a todos los niveles. Respecto a las consecuencias de sentirse o no amado durante los primeros meses de vida, los alumnos destacaron su importancia en relación al desarrollo socio-emocional. En relación al piel con piel, la mayoría de los alumnos hizo referencia a la facilitación del vínculo. Proponemos una mirada más profunda que permita dar a conocer a los futuros maestros las necesidades de los bebés y las familias durante el período perinatal.

Published: June 2020

En los últimos tiempos, la sociedad ha experimentado cambios, que ha llevado a analizar en profundidad las relaciones familiares, siendo la relación entre abuelos/as y nietos/as, la que ha causado mayor interés para los/as investigadores/as en las últimas décadas por la trascendencia que tienen los/as abuelos/as en la vida de sus nietos/as, creándose entre ellos/as una relación especial que no se establece con ningún otro miembro de la unidad familiar. La familia puede ser entendida como un conjunto o sistema estructurado, entre ellos existen lazos y relaciones afectivas, compartiendo metas, objetivos y proyectos comunes, creando una unidad que permite el reparto de funciones y responsabilidades entre sus miembros, por lo que un cambio en una de las partes repercute en las demás, y a consecuencia, de los cambios sufridos en la sociedad, los/as abuelos/as han adquirido una gran importancia en las relaciones familiares, concretamente en la relación con sus nietos/as. Con el fin de conocer las relaciones familiares especialmente entre abuelos/as y nietos/as, las dificultades de dicha relación ante situaciones de ruptura familiar, los derechos que ostentan los/as abuelos/as frente a sus nietos/as, y del conocimientosobre los/as abuelos/as de los recursos existentes en materia de familias. Se ha llevado a cabo un estudio con diseño cualitativo fenomenológico a través de cuestionario en muestra de 46 participantes, abuelos/as de Gran Canaria, con edades comprendidas entre los 58 y 85 años un 67% mujeres, y relación con hijo/as muy buena en el 54.3%, buena 34.7% y regular 10.8%. Se concluye que la principal dificultad para mantener una óptima relación entre abuelos/as y nietos/s está la separación/divorcio de sus hijos/as, por lo que se recurre en muchas ocasiones a la vía judicial.

Published: June 2020

Los objetivos de este trabajo fueron: describir el nivel de satisfacción de las necesidades psicológicas básicas y de inteligencia emocional de estudiantes adolescentes de secundaria, y comprobar la capacidad de predicción de la primera en la segunda. Para ello se respondieron a las versiones validadas al castellano de la Basic Psychological Needs in Exercise Scale y la Trait Meta-Mood Scale. La muestra estuvo compuesta por 464 alumnos de secundaria de 12 a 17 años. Los resultados del análisis descriptivo y de correlación indicaron que la necesidad psicológica que más sienten tener satisfecha fue la relación con los demás y que fue la dimensión reparación emocional la que obtuvo mayor puntuación. Por otro lado, mediante análisis de regresión lineal se halló que la necesidad psicológica que mayor predicción tuvo sobre las necesidades psicológicas básicas fue la relación con los demás. Los resultados obtenidos indicaron que las personas con mayor necesidad de relacionarse tenderán a desarrollar una mejor inteligencia emocional.

ABSTRAKLimbah cair merupakan salah satu hasil dari proses produksi yang mengandung beberapa campuran atau senyawa kimia yang berbahaya. Salah satunya adalah limbah cair dari proses pengolahan monasit yang mengandung unsur radioaktif, yaitu uranium (U). Limbah cair yang mengandung unsur radioaktif, terutama uranium, menjadi bahan berbahaya apabila terlepas ke lingkungan karena kanndunga nuklida aktif nya yang dapat mempengaruhi kesehatan lingkungan dan masyarakat. Oleh karena itu, perlu dilakukan pengolahan limbah cair dari pengolahan monasit. Metode yang digunakan adalah proses pertukaran ion dengan resin kation yaitu Tulsion T-40 Na yang dapat menurunkan kandungan uranium dan kandungan kation lainnya pada limbah cair pada konsetrasi rendah. Pertukaran ion dilakukan melalui proses pengadukan dengan variasi bobot resin dan waktu kontak. Pengukuran kandungan uranium dilakukan dengan Spektrofotometer UV-Vis, sedangkan pengukuran pH dan nilai TDS pada limbah cair dilakukan untuk mengetahui karakteristik limbah. Hasil penelitian menunjukkan kondisi optimum proses pertukaran ion pada bobot resin 1,5 g dengan waktu kontak selama 300 menit menghasilkan penurunan kadar uranium sebesar 83,40 %.ABSTRACTWaste-water is one of the production process that contains several dangerous mixtures or chemical compositions. One of them is waste-water from monazite processing which is containing radioactive element like uranium (U). Waste-water with radioactive content, mainly uranium, became a hazardeous content if it is released to the environment because of its active nuclide content that effect the environment and community health. Therefore, it is necessary to treat waste-water from monasite processing. The method used is ion exchange process with a cation resin, namely Tulsion T-40 Na, which can reduce uranium content and other cations in waste-water at low concentration. Ion exchanging is conducted through stirring process with resin weight and contact time variations. Measurements on uranium content are carried out using the UV-Vis Spectrophotometer, while measurements on pH and TDS values in waste-water are conducted to determine the characteristics of the waste. The results showed that optimum condition of the ion exchange process at 1.5 g resin weight with 300 minutes contact time is resulting a reduction on uranium content as much as 83.40 %.

ABSTRAKPengolahan monasit Bangka secara basa dilakukan melalui tahapan dekomposisi; pelarutan parsial pH 3,7; pengendapan parsial pH 6,3; dan pengendapan total pH 9,8. Proses tersebut menghasilkan natrium fosfat, Rare Earth (RE) hidroksida, uranium (U), dan torium (Th). Pada proses dekomposisi, 99 % natrium fosfat telah terambil dan RE hidroksida telah terpisah dari U dan Th dengan recovery 85 %. Sementara itu, U dan Th yang dihasilkan masih bercampur sehingga perlu dipisahkan. Pemurnian Th dari U pada monasit telah dilakukan dengan metode Solvent Impregnated Resin (SIR) dan dilanjutkan dengan proses elusi setelah SIR. Hasilnya, Th masih berada pada fase cairan berupa larutan torium nitrat [Th(NO3)2] sehingga perlu diendapkan sebagai torium hidroksida [Th(OH)2] untuk memudahkan proses berikutnya. Pengendapan Th setelah proses SIR dilakukan dengan tujuan memperoleh kondisi optimum pengendapan. Resin penyokong yang digunakan adalah amberlite XAD-16 menggunakan ekstraktan yang diimpregnasikan dengan tributyl phosphate (TBP), reagen elusi asam nitrat (HNO3) encer dan reagen pengendapan amoniak (NH4OH). Parameter yang diteliti adalah pengaruh pH dan waktu pengendapan terhadap recovery Th. Hasil penelitian menunjukkan kondisi optimum pengendapan Th dari monasit setelah proses SIR pada pH 1,2 dan waktu 60 menit dengan recovery 84,74 % Th; 3,26 % U; 34,74 % RE; dan 8,52 % PO4.ABSTRACTAlkaline processing of Bangka monazite is carried out through stages like decomposition; partial dissolution pH 3.7; partial precipitation pH 6.3; and total precipitation pH 9.8. These procesess produce sodium phosphate, Rare Earth (RE) Hydroxide, uranium (U), and thorium (Th). On decomposition procsess, 99 % of sodium phosphate had been recovered and RE Hydroxide was separated from U and Th with 85% recovery. Meanwhile, the U and Th products were still mixed so that needs to separate. Purification of Th from U in monazite had been carried out by using Solvent Impregnated Resin (SIR) method and continued by elution after SIR. The result is that Th is still in the liquid phase as thorium nitrate [Th(NO3)2] solution so it needs to be precipitated as thorium hydroxide [Th(OH)2] to facilitate the next process. Precipitation of Th after SIR process is conducted with the aim to obtain optimum precipitation condition. The supporting resin used is amberlite XAD-16 with impregnated tributyl phosphate (TBP) extractant, dilute nitric acid (HNO3) as elution reagent, and ammonium hydroxide (NH4OH) as precipitation reagent. The observed parameters are the effect of pH and precipitation time on Th recovery. The results show that the optimum precipitation conditions of Th from monazite after SIR process is on pH 1.2 and 60 minutes time, resulting recovery of 84.74 % Th, 3.26 % U, 34,74 % RE, and 8.52 % PO4.

ABSTRAK Terowongan Eksplorasi Uranium Eko Remaja Kalan (TEURK) di Kalimantan Barat yang dibangun pada tahun 1980 merupakan salah satu sarana penelitian cebakan uranium di Indonesia. Terowongan ini menembus Bukit Eko Remaja sepanjang 618 m, mulai dari pintu Remaja hingga TRK-7. Mineralisasi uranium di lokasi ini dikontrol oleh urat-urat tak beraturan (stockwork) yang sangat rapat pada batuan metalanau dan metapelit. Tingginya kerapatan struktur geologi tersebut membentuk beberapa zona lemah di dalam terowongan. Zona lemah tersebut berpotensi menyebabkan terjadinya longsor batu dan tanah. Penyangga sementara terbuat dari tiang-tiang kayu dipasang di zona tersebut untuk perkuatan terowongan. Saat ini tiang kayu tersebut tidak lagi mampu menyangga terowongan sehingga sering terjadi longsor batu dan tanah di dalam terowongan. Penelitian ini bertujuan untuk mengetahui kualitas massa batuan aktual dan menentukan jenis perkuatan yang sesuai agar terowongan tetap aman. Survei palu Schmidt dan scanline pada zona tak berpenyangga (kedalaman 50–297 m dan 355–538 m) dilakukan untuk mengambil data parameter klasifikasi Rock Mass Rating (RMR). Hasil pengukuran menunjukkan bahwa massa batuan TEURK di kedalaman tersebut memiliki nilai RMR 52-71 (sedang–baik). Perkuatan yang direkomendasikan adalah pemasangan baut batu dan beton semprot konvensional.ABSTRACT Tunnel for Exploration of Uranium Eko Remaja Kalan (TEURK) in West Kalimantan, built-in 1980, is one of the uranium deposit research facilities in Indonesia. The tunnel penetrated Eko Remaja Hill along 618 m, from Remaja to TRK-7 access. Uranium mineralization in this area controlled by dense stockwork veins on metasilt and metasandstone rocks. The high-dense geological structures create some weak zones in the tunnel. These zones are potentially causing rocks and soil slides. Temporary supports made of wood-piles were installed in these zones to support the tunnel. Currently, these piles are not capable at the tunnel, so that rocks and soil slides occurred inside the tunnel. The research aimed to determine the quality of actual rock mass and determine the appropriate type of reinforcement to keep the tunnel safe. Schmidt hammer and scanline surveys on the unsupported zone (50–297 m and 355–538 m depth) carried out to collect the classification parameter data of Rock Mass Rating (RMR). The measurement result shows that the rock mass of TEURK on the depth has an RMR value of 52–71 (fair-good). Reinforcement recommendations for the tunnel are rock bolts and conventional shotcretes installation.

Microstructure and phase distribution of innovative Oxide Dispersion Strengthened (ODS) steel based on Fe-Cr-ZrO2 particularly for application at high temperature reactor with variation of Cr content was analysed. The alloy was synthesized with Cr composition variation of  15, 20 and 25 wt.% Cr, while zirconia dispersoid kept constant at 0.50 wt.%. The samples was synthesized by mechanical alloying comprising of high energy milling for 3 hours followed by vibrated compression with iso-static load at 20 ton. The final consolidation was performed via sintering process for 4 minutes using the Arc Plasma Sintering (APS) technique, a new method developed in BATAN especially for synthesizing high temperature materials. The samples were then characterized by means of scanning electron microscopy (SEM) with energy dispersed X-ray (EDX) analysis capability and X-ray diffraction. The mechanical property of hardness was measured using standard Vickers micro hardness tester to confirmed the microstructure analysis.  The results show that the microstructure of the ODS alloy samples in all variation of Cr content consists generally of cubic Fe-Cr matrix phase with small of porosity and  Zirconia particles distributed homogenously in and around the matrix grains. The achievable hardness was between 142 and 184 HVN dependent consistently on Cr content in which Cr element may cause grain refining that in turn increase the hardness.
INVESTIGATION ON INHERENT SAFETY OF ONE FLUID-MOLTEN SALT REACTOR (OF-MSR) WITH VARIOUS STARTING FUEL
Authors: Dwijayanto R. Andika Putra , Hermawan Dedy Prasetyo
Published: June 2020

Molten salt reactor (MSR) is often associated with thorium fuel cycle, thanks to its excellent neutron economy and online reprocessing capability. However, since 233U, the fissile used in pure thorium fuel cycle, is not commercially available, the MSR must be started with other fissile nuclides. Different fissile yields different inherent safety characteristics, and thus must be assessed accordingly. This paper investigates the inherent safety aspects of one fluid MSR (OF-MSR) using various fissile fuel, namely low-enriched uranium (LEU), reactor grade plutonium (RGPu), and reactor grade plutonium + minor actinides (PuMA). The calculation was performed using MCNPX2.6.0 programme with ENDF/B-VII library. Parameters assessed are temperature coefficient of reactivity (TCR) and void coefficient of reactivity (VCR). The result shows that TCR for LEU, RGPu, and PuMA are -3.13 pcm, -2.02 pcm and -1.79 pcm, respectively. Meanwhile, the VCR is negative only for LEU, whilst RGPu and PuMA suffer from positive void reactivity. Therefore, for the OF-MSR design used in this study, LEU is the only safe option as OF-MSR starting fuel.Keywords: MSR, Temperature coefficient of reactivity, Void coefficient of reactivity, Low enriched uranium, Reactor grade plutonium, Minor actinides

Background

Heat wave early warning systems help alert decision-makers and the public to prepare for hot weather and implement preventive actions to protect health. Prior to harmonization, public health units across Ontario either used independent systems with varying methodologies for triggering and issuing public heat warnings or did not use any system. The federal government also issued heat warnings based on different criteria. During heat events, adjacent public health units in Ontario and the federal government would routinely call heat warnings at different times with separate public messages, leading to confusion. This article describes the collaborative process and key steps in developing a harmonized Heat Warning and Information System (HWIS) for Ontario.

Setting

Public health units across Ontario, Canada, collaborated with the federal and provincial government to develop the harmonized HWIS for Ontario.

Intervention

In 2011, stakeholders identified the need to develop a harmonized system across Ontario to improve heat warning services, warning criteria, and health messaging. Through a 5-year process facilitated by a non-governmental organization, the three levels of government collaborated to establish the Ontario HWIS.

Outcomes

The province-wide HWIS was implemented in 2016 with the Ontario Ministry of Health and Long-Term Care’s release of the harmonized HWIS Standard Operating Practice, which outlined the notification and warning process.

Implications

The lessons learned could help spur action in other provinces and jurisdictions internationally in the development of similar health evidence-based warning systems, including in particular those for protecting public health during extreme heat events.
Qualitative & Quantitative Assessment of Human Islets for Distribution Using Dithizone (DTZ) v2
Authors: Islet Distribution Program Integrated
Published: June 2020

This Standard Operating Procedure is adapted from the work of the 'National Institutes of Health-Sponsored Clinical Islet Transplantation Consortium Phase 3 Trial: Manufacture of a Complex Cellular Product at Eight Processing Facilities'' following the SOP cited in the document 'Purified Human Pancreatic Islet: Qualitative and Quantitative Assessment of Islets Using Dithizone (DTZ) – Standard Operating Procedure of the NIH Clinical Islet Transplantation Consortium' This SOP defines the assay method for quantitative and qualitative determination in the identification of human isolated islet preparations, which include endocrine and exocrine tissue, for use in the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored research in the Integrated Islet Distribution Program (IIDP). This protocol is written to assist the participating islet isolation centers and investigators who are part of this program. Dithizone (diphenyl thiocarbazone; DTZ) is an organic chemical that chelates the zinc in the insulin granules present in the beta cells of the pancreatic islets. The islet cells are stained red while the acinar cells remain unstained. DTZ staining is used as a lot release and as an in-process assay: (i)Lot release testing: DTZ staining is used to identify islets and to determine the quantity and quality of the final islet product. Islet quantity is expressed as the number of islet equivalents (IEQ), which is calculated based on the number and diameter of the islets present in the preparation, mathematically corrected for islet volume. (ii)In-process testing: DTZ staining is used to identify islets and to assess the effectiveness of the digestion, isolation and purification processes. The quality of the preparations is expressed as percent islet purity, and percent trapped islets. Islet quantity (IEQ) is also assessed.
