Authors: Ayyıldız Merve , Tengiz Zehra Meliha , Çiçek Adnan
Published: August 2024

Dünyada ve Türkiye’de patatese yönelik ciddi talep artışı karşısında arz güvencesinin sağlanması önem arz etmektedir. Bu noktada tarımda sözleşmeli üretim modeli etkili araçlardan biri olarak öne çıkmaktadır. Sözleşmeli üretim modelinin yaygınlaşması, geliştirilmesi ve iyileştirilmesi sürdürülebilir tarım ve tarıma dayalı sanayi açısından önemlidir. Bu çalışmada Kayseri ili Tomarza ilçesinde sözleşmeli patates yetiştiriciliği yapan üreticilerden yüz yüze anket yoluyla 2023 yılında elde edilen veriler ışığında mevcut durum ortaya konulmuştur. Araştırma sonuçlarına göre, üreticilerin patates yetiştiriciliğindeki tecrübesi ortalama 5.8 yıl, sözleşmeli patates yetiştiriciliğinde 2.9 yıl olduğu belirlenmiştir. İşletmelerin ortalama 286.1 da olan arazi varlığının %48.8’inin patates ekimine ayrıldığı ve 114.5 da alanda sözleşmeli ekim yapıldığı tespit edilmiştir. Bölgedeki üreticilerin %57’sinin tek ve aynı firmayla anlaşma yapıyor olması bölgede tekelcilik sorununu işaret etmektedir. Gelecek yıl işletmelerin sözleşmeli alanlarını azaltacakları belirlenmiştir. Büyük ölçekli işletmelerde bu oran daha yüksek iken girdi temini, sermaye yetersizliği gibi faktörlerden dolayı küçük işletmelerde daha az olacağı gözlenmiştir. Sonuç olarak bölgede sözleşmeli tarımın yaygın olduğu fakat fiyat ve fire nedenlerinden dolayı üreticilerin sözleşme harici üretime yöneleceği söylenebilir. Bu noktada üretici ve firma menfaatini dengeleyecek yasal mevzuatta fiyat belirlemeye yönelik hükümlere yer verilmesinin sözleşmeli üretimin yaygınlaştırılmasına ve sürdürülebilirliğine katkı sağlayacağı düşünülmektedir.

Published: August 2024

The Amik Plain, where the experiment was conducted, is increasingly salinised owing to improper irrigation methods, excessive irrigation, drainage and groundwater use. This situation indicates that soil salinity will increase even more in the future. The study was conducted using a factorial experimental design in potted conditions inside the greenhouse to investigate the impacts of three distinct levels of irrigation water salinity (ECi) (ECi-0= 0.5 dS m-1 (control), ECi-2= 2 dS m-1and ECi-4= 4 dS m-1) and four different leaching fraction (LF) (LF0=0%, LF10=10%, LF20=20%, LF30=30%) on stomatal conductance (gs), leaf surface temperature (LSt), chlorophyll content (SPAD), chlorophyll concentrations (Chl-a, Chl-b, and Chl-tot) and yield parameters in 'Cospirina' lettuce plants. As a result of the study, soil salinity (ECe) increased from 0.82 dS m-1 to 2.09 dS m-1 with increasing ECi. As ECi increased, plant water consumption (PWC) decreased from 8.92 to 5.71 L pot-1, yield decreased from 276 g pot-1 to 198 g pot-1, gs decreased from 266 mmol m-2 s-1 to 215 mmol m-2 s-1. LSt increased by 2.17% in ECi-2 and 6.4% in ECi-4 compared to the control. As ECe increased, yield decreased by 10% in ECi-2 and 28% in ECi-4 compared to the control treatment. Chl-tot and Chl-a were significantly affected by the increase in ECe (r2=0.96*, r2=0.99**, respectively), while Chl-b was not affected. In contrast to soil salinity, leaching fraction had a positive effect on plant physiology.

Published: August 2024

The installation and laying of underwater pipelines are the cornerstone of ocean engineering. They are crucial to the distribution of important fossil energy sources such as oil and natural gas around the world. Welding technology is an indispensable part of pipe connection. A new welding method is proposed to improve the quality of welded joints of underwater cast steel pipelines, which is the flux band-constrained arc ultra-narrow gap welding (UNGW) method. UNGW has unique welding advantages compared to traditional welding methods, including high welding efficiency, excellent welding joint performance, small welding deformation, and low welding heat input. The experimental study on UNGW for the application of underwater cast steel pipeline is conducted by manipulating the welding parameters, such as the welding arc voltage and welding current, and observing the microstructural and mechanical properties of the weld. The optimal range of welding parameters for weld formation are welding voltage of 22 V, welding current of 200-230 A, and welding speed of 8.25-9 mm/s. The microstructure analysis of the welded joints observed a mixture of tempered martensite, bainite, and retained austenite are detected at Heat Affected Zones (HAZ), whereas the results of microhardness showed no softening occurred in the welded joints. The composition of the flux band can be manipulated to improve the fusion of air bubbles and side walls.

Traditional door lock systems that usually use mechanical locks are now starting to be replaced with electrical and control-based lock systems that have more capabilities than traditional door lock systems. These techniques are an integration of mechanical devices, electronics, and intelligent control devices. One of the important features of this innovative lock system is its simplicity and high efficiency. In this research, an automatic lock system was constructed by combining mechanical and electrical components into a device. A microcontroller Arduino was used to control the whole functions of the system.  The input component for this system is an RFID card or RFID Tag. An RFID reader is installed on the device to detect the RFID card used when accessing the door whether a registered card or not. A solenoid door lock is used as an output that will function as a door lock mechanism. The door lock system developed in this study is integrated with the attendance system database. The result of this research shows that the system can recognize the identity of the door accessor and is also able to store data in form of identity and time the door is accessed. The solenoid door lock will retract to unlock the door if the door is accessed with a registered RFID card and vice versa solenoid door lock will continue in the push position to lock the door if the door is accessed with a not registered RFID card. Some of the main performances of this system are that RFID read range from 0 - 20mm, RFID sensor can detect the presence of an RFID card even if it is blocked by objects such as papers, plastics, glass, and cloths. When objects such as aluminum or iron are present in between the RFID sensor and the RFID card, it will interfere with the signal so that the RFID sensor cannot detect the presence of the RFID card.

Published: August 2024

Pupuk Iskandar Muda (PT. PIM) generates electricity from two main gas turbine generators (GTGs), one with a capacity of 15 MW and 20 MW respectively. The generator's performance can only be at its best if its operation remains stable, even when it exceeds capacity or faces potential damage from its outdated engine. When the electrical load increases and reaches its maximum capacity, load transfer is commonly accomplished through synchronous generator operation. However, the synchronisation may lead to generator failure. This study focuses on (1) examining the PT's load transfer process of Iskandar Muda fertiliser, operated based on Supervisory Control and Data Acquisition (SCADA), and (2) evaluating the influence of voltage and frequency on this process. This study utilised qualitative methods by directly observing field data at PT PIM. The results obtained indicated that the load transfer process at PT PIM is carried out on two simultaneously operating gas turbine generators using SCADA-based technology. The load transfer process employs two methods, namely fast load transfer and slow load transfer. Changes in the decrease in power in GTG 1 and the increase in power in GTG 2 can cause the generator's rotational speed and the governor's setting point to change, resulting in changes in the voltage and frequency characteristics. The load transfer is performed regularly in stages of 200 kW to maintain the stability of the generator condition. However, a transfer of 1 MW is executed during the final stage to avoid overloading and a potential burden on one of the generators. GTG 1 experiences a voltage increase of 0.018% and a frequency increase of 0.0059% due to load changes in the two generators, whereas GTG 2 has a voltage increase of 0.018% and a frequency increase of 0.0019% when the load shifts from 1 MW to 9 MW.

The building is at significant risk due to structural faults related to the imposed loads. Various circumstances, such as excessive load, inadequate design, or the utilization of substandard materials, might lead to these imperfections. Furthermore, these deficiencies not only impact the well-being of individuals residing in the building but also result in substantial economic setbacks and damage to the standing of those involved. However, to surmount this hindrance, it is imperative that all entities participating in the construction process collaborate, adhere to rigorous quality control protocols, and adhere to building regulations. It is essential to take proactive measures at each phase of construction to minimize flaws associated with loads. This involves a comprehensive analysis of the structure carried out during the design phase, careful oversight of the materials and methods used during construction, and regular inspections and maintenance once the building is completed. Consequently, the structure can enhance its ability to withstand and recover from damage, as well as extend its overall duration, all while ensuring the safety of its occupants and the surrounding community. Furthermore, it is imperative to engage in ongoing surveillance and upkeep to detect any such imperfections and rectify them before they escalate into more significant complications. Preventive maintenance programs, structural appraisals, and routine inspections can help discover early signs of degradation or structural weakness, allowing for prompt action and correction. In addition, investing in contemporary technology such as structural health monitoring systems can offer immediate and accurate information about the condition of buildings, so enabling effective risk management and proactive maintenance strategies. In conclusion, it is crucial to address any flaws in building load-related issues to ensure the sustainability and safety of the structure.

Published: August 2024

The pelletization of biomass has the potential to replace fossil fuels as a source of energy. Pellet characteristics such as high durability and low moisture content are essential for making a good pellet. There are currently no studies on the physical, chemical, and mechanical properties of pellets made from a mixture of Palm Kernel Shell (PKS) and Polystyrene Plastic (PS). The focus of this research is to analyze the effect of different PS mass percentage on the physical, chemical, and mechanical properties of PKS-PS pellets. The PKS-PS mixture percentage is varied from 100%-0%, 70%-30%, and 50%-50% with varying corn starch binder percentages of 0%, 2%, and 4%. From the findings, increasing the PS mass percentage in the mixture decreases the density and moisture content. Furthermore, increasing the PS mass percentage increases the volatile matter while decreasing the ash content. Compressive strength and impact resistance increase significantly with higher PS mass percentage. Adding corn starch as a binder agent increases the impact resistance and compressive strength of the pellet, regardless of the PKS-PS mixture percentage.  To conclude, producing pellet blends of PKS and PS utilizing corn starch as a binder agent has excellent results for both mechanical properties testing, resulting in high-quality pellets that are less prone to breaking during combustion.

Published: August 2024

Cement industries are widely used in construction and contributing around 5% to 7% of the total global carbon dioxide emission in the world. Recent research has focused on developing new types of cementitious mortars with enhanced properties. One such material that has been studied for its potential benefits is magnesium oxide (MgO). MgO can participate in the cement hydration reactions, enhance carbon capture ability, and improve the durability of cementitious mortars. This research paper discusses the impacts of integrating MgO as a cement alternative on cementitious mortars compressive strength, water absorption by capillary action, and carbonation. Two various reactive MgO samples that are readily accessible on the market were assessed as partial cement replacements (at 10%, 15%, and 20%, by weight) in the manufacture of mortars. The findings indicate that when it comes to compressive strength, it is better to have less MgO, exactly 10% or less. When water is absorbed through capillary action, it is best to use MgO values of 10% or less. In terms of carbonation protection, it is best to think about MgO concentrations of 15% or higher. In addition, the article stresses the fact that specimens with a greater content of MgO had a higher carbon dioxide absorption and a faster rate of carbonation. Overall, the use of MgO in cementitious mortars has the potential to improve their properties and reduce their environmental impact.

Desde sua gênese no início dos anos 2000 até o presente, o BRICS (Brasil, Rússia, Índia, China e África do Sul) evoluiu para uma aliança com propósitos definidos, advogando por reformas em importantes instituições multilaterais. Este artigo analisa a paisagem macroeconômica dentro do BRICS, enfatizando o fortalecimento de parcerias, o aumento do comércio e as colaborações econômicas estratégicas entre seus membros. A influência crescente do BRICS é examinada através da recente adição de seis novos membros, incluindo Argentina, Egito, Etiópia, Irã, Arábia Saudita e Emirados Árabes Unidos, com o objetivo de unir países que representam 30% do produto interno bruto (PIB) global e 43% da produção global de petróleo. Enquanto apresenta oportunidades para crescimento econômico e influência geopolítica, essa expansão também apresenta desafios em alinhar interesses diversos. O artigo escrutina o impacto potencial do BRICS Plus nos mercados globais, enfatizando sua capacidade de realinhar o comércio e as finanças internacionais e seu papel na modelagem do futuro das cadeias de suprimentos globais.

Published: August 2024

O campo da análise de políticas públicas (APP) tem, há décadas, destacado o papel de uma diversidade de atores não estatais na produção das políticas. Para os estudiosos da política externa, contudo, está continua sendo uma questão periférica, ainda que, em muitos casos, a política exterior tenha se politizado a ponto de despertar o interesse e o ativismo por parte de variados atores da sociedade civil. Com o objetivo de preencher parte dessa lacuna, este trabalho busca, de maneira exploratória, discutir as razões, lógicas e interesses das redes transnacionais em suas tentativas de pautar o processo de produção da política externa. Para tanto, o artigo está estruturado em três seções principais. Primeiramente, é apresentada uma radiografia dos estudos sobre as policy networks desenvolvidas no campo da APP, que trata brevemente da questão conceitual, discute a diversidade das redes, analisa as suas formas de atuação e tenta entender como se organiza, propriamente, o subcampo analítico. Em seguida, discute-se como as redes transnacionais têm sido compreendidas no campo acadêmico das relações internacionais (RI). Feita uma apreciação mais geral, a seção focaliza as comunidades epistêmicas e as chamadas transnational advocacy networks, ressaltando seus objetivos, estratégias e formas de atuação. Por fim, são selecionadas duas tipologias para que sejam apontadas, de maneira hipotética, as variadas maneiras e os momentos em que as redes transnacionais podem impactar a produção da política externa dos Estados nacionais.
Aportes do campo da Análise de Política Externa (APE) ao tratamento científico de Monitoramento e Avaliação da Política Externa (M&A/PE): pequenos avanços ante enormes obstáculos
Authors: Desiderá Neto Walter Antonio
Published: August 2024

No campo da análise de política externa (APE), pesquisas com foco avaliativo são notavelmente pouco representadas entre as diversas áreas temáticas. Essa condição marginal é evidente tanto na limitada quantidade de estudos publicados quanto na quase total ausência dessas ideias nos principais quadros teóricos e conceituais. Para contrariar essa tendência, este artigo exploratório busca identificar e examinar contribuições dentro do campo que visaram direta ou indiretamente fornecer um quadro conceitual, teórico e/ou metodológico para o monitoramento e a avaliação da política externa (M&A/PE). O propósito deste empreendimento é duplo: primeiro, delinear os principais desafios enfrentados por acadêmicos nesta área; e segundo, organizar os progressos mais significativos que eles alcançaram. Apesar da escassez de trabalhos disponíveis, compilar suas percepções é crucial. Esta síntese servirá como uma base para futuras pesquisas voltadas ao desenvolvimento de ferramentas que propiciem a execução dessas tarefas.

Authors: Mariano Marcelo Passini , Ramanzini Junior Haroldo
Published: August 2024

Observam-se, nas últimas décadas, avanços significativos na dimensão substantiva e no aspecto metodológico das pesquisas desenvolvidas no campo de análise de política externa e de política externa brasileira. Entretanto, ainda subsistem lacunas, do ponto de vista da elaboração de instrumentos, tipologias e análises mais diretamente focadas nas dimensões de implementação, monitoramento e avaliação da política externa. Desse modo, o objetivo do texto é examinar as possibilidades de monitoramento e avaliação da política externa brasileira. Para isso, incorporam-se as contribuições dos modelos mais gerais de monitoramento e avaliação de políticas públicas, particularmente a metodologia do modelo lógico, ao mesmo tempo que se consideram as complexidades e desafios específicos que caracterizam a implementação da política externa. Em que pesem a identificação de limitações e a consequente necessidade de adaptação dos modelos normalmente utilizados para o monitoramento e a avaliação de políticas públicas, faz-se necessário avançar no debate e no aprimoramento das ferramentas de monitoramento e avaliação na política externa, considerando a crescente interconexão entre questões internas e externas e a necessidade de definir indicadores apropriados de desempenho.
Queer and postcolonial theories: understanding brazilian immigrant policy during Bolsonaro’s Government (2019-2022)
Authors: Barcellos Bruna , Mercher Leonardo
Published: August 2024

Este artigo tem como objetivo compreender o governo Bolsonaro e sua agenda imigratória a partir das teorias pós-coloniais e queer das relações internacionais (RI). Para identificar e coletar dados utilizamos a análise de conteúdo para organizar as sentenças de acordo com quatro categorias das teorias de RI. Estas quatro categorias são: i) colonialidade do conhecimento; ii) colonialidade do poder e do ser; iii) colonialidade da natureza; e iv) colonialidade de gênero. Utilizamos essas categorias para identificar frases em discursos, entrevistas e políticas públicas que reforçam conceitos de colonialidade e visão de mundo binária. Os principais resultados são: presença do presidente e dos seus ministros em eventos críticos contra os imigrantes; xenofobia em relação a grupos específicos de imigrantes, como os latinos; sexismo, homofobia e o reforço de uma percepção binária da família e dos papéis de gênero para os imigrantes.

The research centered on assessing the influence of human factors and associated environmental and job factors on maritime accidents in Tanzania. It pursued three specific objectives: identifying mostly human factors contributing to accidents among maritime professionals, examining challenges affecting their attention to maritime accidents, and proposing strategies tomitigate these factors. The research employed various analyses, including descriptive statistics, regression analysis, and thematic analysis, to achieve its objectives. The study acknowledged that the frequency of occurrence of maritime accidents in Tanzania had remained constant, yet there was a potential for an increase if interventions would not be effectively implemented to address underlying causes. While individual human factors generally had a low influence on maritime accidents, specific factors such as the use of illicit drugs and alcohol, fatigue while performing duties, communication barriers, and non-adherence to safety regulations emerged assignificant contributors. Similarly, human-related challenges had a low influence on the occurrence of maritime accidents in Tanzania. However, their collective influence on maritime accidents highlights the need for inclusive interventions against them. Specifically, density of seatraffic, communication failures between crew members and shore operators, pressures from bosses, and conflicting maritime regulations were noted to be significant challenges that could determine occurrence of maritime accidents. Strategies proposed for lowing maritime accidents in the country were: such as strict enforcement of maritime regulations, ensuring personnel remain well-informed about maritime safety, enhancing communication channels, establishing a safe working environment, observing speed limits, and conducting regular vessel maintenance.

Published: August 2024

A Go-Kart is a four-wheeled vehicle that exhibits characteristics similar to a motorcycle. Additionally, since Go-Kartslack shock absorbers, it is crucial to use an engine that minimizes vibrations. The shaft, a typically circular rotating part, is oftenattached to elements like gears and endures continuous loads, which can lead to breakage. Shaft failures are common and often result from incidents caused by the need to use lightweight materials for faster performance. This study aims to examine the strength characteristics of the Go- Kart rear wheel shaft made from ASTM A414 Grade A steel after undergoing bending tests, impact tests, and microstructure analysis. Specifically, it investigates the effects of temperature on the toughness and curvature of the Go-Kart rear wheel shaft post-normalizing and tempering processes. Methods employed include heat treatment, three-point bending tests, Charpy impact tests, and ASTM E3-11 microstructure analysis. The highest impact value, 0.644joules/mm2, was observed in specimen B, which underwent a normalizing process at 850°C and tempering at 300°C. The lowest impact value, 0.190 joules/mm2, was found in specimen A, which underwent a normalizing process at 800°C and tempering at 250°C. The highest three-point bending strength, 2520.1 N/mm2, was also recorded in specimen B, while the lowest, 2255.4 N/mm2, was in specimen C, which underwent normalizing at 900°C and tempering at 350°C. Microstructure analysis revealed that higher temperatures during the normalizing and tempering processes result in the formation of more pearlite crystals and a denser microstructure.

Published: August 2024

A new gear testing method is introduced to reduce development cost and time. It allows component-level testing of individual gear meshes and new gear designs. Instrumented gear sets are tested at full load while the rest of gearbox components are still being built. Since the fatigue
strength of the gears is determined earlier in the development cycle, design deficiencies are identified and understood earlier. In this new method, an individual gear mesh installed in a stiff facility housing is used to mimic the contact pattern and bending stress demonstrated by the same
mesh in an actual aircraft housing. Analytical gear models are used to identify the displacement difference between the stiff test facility and the aircraft housing. The test stand is designed so it can be adjusted accurately to provide gear and pinion positions that are representative of
the deflected positions under load in the aircraft housing. A spiral bevel mesh and a split torque double helical reduction stage with multiple meshes are evaluated using the developed method. The contact pattern and strain survey results of the gear meshes are correlated with predicted results.

Authors: Sharma Aditya , Srivastava Vivek , Singh Brij Bhushan , Ansari Mumtaz Ahmad
Published: August 2024

A Spigelian hernia is an uncommon, atypical protrusion of the peritoneum or abdominal contents via a defect (Spigelian fascia), consisting of the internal oblique aponeuroses and the transversus abdominis. With a frequency ranging from 0.12% to 2% of all abdominal wall hernias, Spigelian hernias are extremely rare. It usually arises from a condition that increases intra-abdominal pressure, the degeneration of the abdominal aponeurotic layers or trauma to the abdominal wall. Herein, we present a case series of patients with varying presentations of Spigelian hernia who presented, who were promptly diagnosed and who were managed successfully with laparoscopic surgical repair.
