Authors: Ertürk Nihat , Arıcak Burak
Published: June 2024

In this study, it was aimed to determine the current status of red pine (Pinus brutia Ten.) distribution areas in Kastamonu Forestry Regional Directorate, which is the Forestry Regional Directorate with the highest production in Türkiye, and the possible changes in suitable distribution areas due to global climate change. In the study, in addition to the current suitable distribution areas of red pine (Pinus brutia Ten.), suitable distribution areas in 2040, 2070 and 2100 according to SSP 126, SSP 370 and SSP 585 scenarios were determined. The results of the study show that there may be a loss of more than 15% (approximately 114,5 km2) in the suitable distribution areas of red pine populations in Kastamonu until 2100 due to the effects of climate change. It does not seem possible for the species to adapt to these changes without human intervention. Therefore, it is recommended that necessary adjustments should be made in forest management plans taking into account the results of the study.
Reduced Graphene Synthesis via Eco-Friendly Electrochemical Exfoliation Method
Authors: Bilgiç Gülbahar
Published: June 2024

A novel approach to mass producing graphene without inadvertent damage was needed to meet the increasing demand for the material. Graphite electrochemical exfoliation (EE) is an intriguing method for the large-scale, quick, and easy manufacture of graphene. Using leftover whey as an electrolyte, the EE of commercial graphite was examined in this work. It was shown that a straightforward and affordable exfoliation technique may produce graphene that, in the absence of functionalization or surfactant, forms a stable dispersion in the waste solvent. Because wastewater is acidic, it has been shown that storing it at +4 degrees aids EE. X-ray diffraction (XRD) was used to satisfactorily validate the manufactured graphene's existence. The results point to a low-cost method of producing graphene and graphene oxide.

Authors: Şevik Hakan , Elajaıl İbrahim Saleh
Published: June 2024

In this study, the variation of arsenic (As), cadmium (Cd), nickel (Ni) and selenium (Se) concentrations in some materials used as concrete admixtures were evaluated. These heavy metals are extremely hazardous elements for both human and other living organisms and the environment. Due to these hazards, they are on the priority pollutant list of both ATSDR and EPA. Study results show that heavy metal concentrations in some additives are at very high levels. As a result of the study, the highest As concentrations were obtained in copper slag, vermiculite and cem III cement, the highest Cd concentrations in crushed stone and copper slag, the highest Ni concentrations in copper slag, wood ash and brick powder, and the highest Se concentrations in blast furnace slag and cem III cement. This may pose a great risk to the health of people working in the industry and the environment.
Le continuum du vivant
Authors: Mulhauser Blaise
Published: June 2024

L’étude du vivant reste marquée par un certain anthropocentrisme, dont les biologistes peinent à se défaire. En s’appuyant sur l’état actuel et pluridisciplinaire des connaissances, aussi bien théoriques qu’expérimentales, cet ouvrage propose un changement de paradigme révolutionnaire qui impacte notre compréhension de la vie, de son évolution et, au-delà, qui interroge notre place dans le monde et dans l’Univers. Après avoir introduit les notions de symbiose puis de microbiote –ce «monde en soi» qui participe non seulement au bon fonctionnement de son hôte, mais également à son comportement–, l’auteur se penche sur les origines de la vie et explique comment l’ensemble des êtres multicellulaires symbiotiques, des plus fondamentaux aux plus complexes, sont issus d’une absolue nécessité de coopérer, et ce, jusque dans leur mort. Il ne s’agit plus dès lors de savoir si les espèces luttent ou fusionnent pour survivre, mais de comprendre que le vivant forme un tout, un « continuum ». Enfin, le livre examine les questions d’évolution, de socialité, de conscience et de croyance, avant de proposer une ambitieuse définition, universelle dans le sens naturaliste du terme, de ce qu’est la vie. En démontrant la pertinence de ce «continuum du vivant» et de la nécessité de lui consacrer une approche «symbiologique», cet ouvrage ouvre à l’étude du vivant les portes d’une nouvelle ère.

Şeybânîler ve Bâbürlüler Rekabetinin (1500-1599) Meydana Getirdiği Jeo-Politik Parçalanma
Authors: Macit Abdulkadir
Published: June 2024

İslam tarihinde 16. yüzyıl Müslüman toplumlarda yeni siyasal düzenlerin ortaya çıkması itibariyle dikkat çekicidir. Bu yüzyılda Osmanlılar, Safevîler ve Bâbürlüler şeklinde üç büyük devlet ve Timurluların özellikle Mâverâünnehir ve Türkistan topraklarında Özbekler ve Kazaklar gibi hanlıklar ortaya çıkmıştır. Bu yeni düzenler, beraberinde yeni çatışma alanlarını ve aralarında çok boyutlu bir rekabeti ön plana çıkarmıştır. Bu rekabette özellikle Şeybâniler-Bâbürlüler mücadelesi İslam dünyasının doğusunda bulunan Mâverâünnehir, Horasan ve Hint Alt Kıtası arasında jeo-politik bir kopuş meydana getirmiştir. Bu kopuş sebebiyle Şark İslam’ı arasında insan-toplum, bilgi-fikir ve mal-ticaret hareketliliği ve akışı tıkanmaya başlamıştır. Bu çalışmada Şark İslam’ı arasında bulunan Şeybânîler ile Bâbürlülerin rekabetinin özellikle Timurluların mirasını elde etmeye yönelik meydana geldiği ortaya konulmuştur. Dolayısıyla bu çalışma Mâverâünnehir-Horasan-Hint Alt Kıtası merkezli yaşanan tüm bu çatışmaların özelde Şark İslam’ında siyasî, coğrafî, ticarî, ilmî ve kültürel bütünlüğün parçalanması olduğunu tahkik etmiştir. Bu sayede Müslümanlarda sonuçlarını doğrudan birkaç yüzyıl içinde gözlemlediğimiz durağanlaşma ve daralmanın kökenleri Şeybânîler ve Bâbürlüler mücadele örnekleminden hareketle aşikar hale getirilmiş olacaktır.

O trigo (Triticum aestivum) apresenta relevância em todo o mundo pelo seu alto valor nutritivo e amplo consumo humano e animal. A qualidade da farinha de trigo é uma das variáveis mais importantes para a panificação, porém a mesma apresenta elevada dependência das condições climáticas, e para tanto, metodologias como a dessecação em pré-colheita são utilizadas a fim de acelerar o ciclo e antecipar a colheita. Atualmente no Brasil está registrado o produto denominado Glufosinato de amônio, que inibe a atividade da enzima glutamina sintetase (GS), promovendo a morte celular, porém podendo resultar em alteração na qualidade da farinha. Desta forma, o objetivo do presente trabalho foi avaliar o efeito da aplicação de doses de secante em pré-colheita na qualidade da farinha de duas cultivares de trigo na região Noroeste do Rio Grande do Sul. O experimento foi conduzido em Delineamento em Blocos Casualizados – DBC, compostos por duas cultivares de trigo (TBIO Toruk e TBIO Sossego), com quatro dosagens de glufosinato de amônio e quatro repetições, totalizando 32 parcelas. Após a colheita, realizou-se a análise de qualidade industrial dos grãos de trigo pela espectroscopia de infravermelho próximo-NIRS. Como resultado observou-se que a utilização do glufosinato de amônio na época e dosagens deste estudo não modificou os parâmetros de Teor de umidade, Proteína, Número de queda, Força de qlúten, Absorção de água, Tempo de desenvolvimento, Estabilidade e Relação P/L. Portanto, as dosagens de dessecante utilizadas para a dessecação não modificaram os atributos de qualidade da farinha de trigo avaliados neste estudo.

Published: June 2024

Mung beans (Phaseolus radiatus L.) were one of the agricultural commodities that have very good prospects for development in Indonesia. Mung beans were the third most important legume commodity after soybeans and green beans. In Indonesia, green bean productivity was still low and cultivation land was limited to marginal land with a productivity of 1.1 tonnes per hectare and a potential yield of 2 tonnes per hectare (BPS, 2019). Causing factors the decline in green bean production include low soil fertility, land conversion, climate factors and cultivation factors. Efforts to increase production were by increasing soil fertility by providing complete fertilizer (NPK) and adding biological fertilizer. So it is necessary to carry out research to increase growth and production of green beans with balanced NPK fertilizer and biological fertilizer. The aim of this research was to determine the application of biological fertilizer to the growth and production of mung bean plants, to determine the application of NPK fertilizer to the growth and production of mung bean plants, to determine the interaction between biological fertilizer and NPK fertilizer on the growth and yield of mung bean plants. The research was conducted in Paleran Village, Umbulsari District, Jember Regency. The research was carried out using a Randomized Block Factorial Design (RAKF) consisting of 2 factors with 3 replications. The data obtained were analyzed of varians followed by Duncan's 5% average test. The conclusion of this research was that biological fertilizer (C2) treatment with a concentration of 5 liters per hectare has an effect on the growth and production of mung beans, NPK (P3) fertilizer treatment with a dose of 400 kg per hectare has an effect on the growth and production of  mung beans, there was an interaction between biological fertilizers 5 liters per hectare with 400 kg NPK fertilizer per hectare (C2P3) on mung bean production variables. It was recommended that the results of this research be used as recommendations for mung bean farmers to increase production on marginal land.

The influence of loading speed on the bending strength of beech (Fagus sp.) and birch (Betula sp.) wood
Authors: Dobrowolska Ewa , Karczmarz Wojciech
Published: June 2024

The influence of loading speed on the bending strength of beech (Fagus sp.) and birch (Betula sp.) wood The subject of this paper was to investigate the effect of loading speeds from 20 mmˑmin-1 to 200 mmˑmin-1 on the flexural strength and deformation of beech (Fagus sp.) and birch (Betula sp.) wood with moisture content close to the absolutely dry state and fibre saturation point. A GOM Aramis measuring system, operating with Digital Image Correlation (DIC) technology, was used in the study to record the displacement and deformation of the elements in real time. The results obtained for flexural strength, flexural modulus and the amount of deformation observed showed a relationship between material properties and loading rate. At higher moisture content, the bending strength and modulus of elasticity decreased with increasing deflexion. The highest bending strength and modulus of elasticity were achieved by the tested wood species at a loading rate of 200 mmˑmin-1. Beech wood, compared to birch wood, showed higher bending strength and modulus of elasticity. Images obtained by means of DIC revealed, at moisture contents close to the dry state, a symmetrical distribution of compressive and tensile stresses relative to the neutral axis of the sample cross-section. At higher moisture contents, there was a significant asymmetry between the compressive and tensile stresses and an apparent shift of the neutral axis towards the tensile surface.
