Authors: Arslankara Veysel Bilal , Seferoğlu Süleyman Sadi
Published: March 2024

Bu çalışmanın amacı mesleki beceri eğitimi alan lise öğrencilerine verilen video dönütlerin onların yansıtıcı düşünme becerilerine olan etkisini incelemektir. Bu kapsamda bir meslek lisesindeki 11. sınıf öğrencilerinden oluşan biri deney diğeri kontrol grubu olmak üzere iki grupla öntest sontest kontrol gruplu seçkisiz desende deneysel bir çalışma gerçekleştirilmiştir. Oryantasyon çalışması ile birlikte toplamda 7 hafta süren çalışmada öğrencilere alanları doğrultusunda üç tane performans beceri görevi verilmiştir. Her görevin ardından ders öğretmeni tarafından, gerekli düzeltmelerin yapılmasını sağlamak üzere video dönütler çekilerek öğrencilere iletilmiştir.
Çalışma grubunda 11 deney, 11 kontrol grubu öğrencisi olmak üzere toplam 22 kişi bulunmaktadır. Araştırma verileri Kızılkaya ve Aşkar (2009) tarafından geliştirilen Problem Çözmeye Yönelik Yansıtıcı Düşünme Becerisi Ölçeği ile toplanmıştır. Elde edilen veriler üzerinde uygulanan normallik testi sonuçlarına göre veriler normal dağılım sergilemediğinden parametrik olmayan testler kullanımıştır. Araştırmada iki temel soru bulunmaktadır. Bunlardan birincisi, deney ve kontrol grubu öğrencilerinin yansıtıcı düşünme becerileri açısından aralarında anlamlı bir farklılık olup olmadığı, diğeri ise deney ve kontrol grubu öğrencilerinin yansıtıcı düşünme becerileri ölçeğine ait öntest ve sontest puanları açısından gruplar lehine anlamlı bir farklılık olup olmadığı şeklindedir. Yapılan analizler neticesinde video dönüt alan öğrencilerin yansıtıcı düşünme beceri düzeyleri daha yüksek çıkmış olup bu sonuç istatistiksel olarak anlamlıdır. Alt boyutlar yönüyle değerlendirildiğinde yalnızca değerlendirme boyutunda anlamlı bir sonucun ortaya çıktığı görülmüştür. Aynı şekilde video dönüt alan öğrencilerin sontest puanları öntest puanlarından daha yüksek çıkmış olup bu sonuç da istatistiksel olarak anlamlı bulunmuştur.

Published: March 2024

Boraboy Gölü, Amasya ilinin kuzeyinde yer alan tipik bir heyelan set gölüdür. Çatağın Deresi vadisini kapatan heyelan setinin gerisinde suların birikmesiyle meydana gelmiştir. Bu çalışmada, Boraboy Gölü'nü oluşturan heyelan kütlesinin jeomorfometrik özelliklerinin Blokaj İndisi (BI), Hapsolmuş Su İndisi (II) ve Boyutsuz Blokaj İndisi (DBI) gibi jeomorfometrik indisler kullanılarak değerlendirilmesi amaçlanmıştır. Elde edilen verilerden Boraboy Gölü'nün üç indise göre Kararlı Oluşmuş Heyelan Set Gölleri sınıfında yer aldığı sonucuna ulaşılmıştır. Jeomorfometrik indislerde indislerin her biri için indis özelinde BI değerinin 8,97 olarak tespit edilmesi, setin hacmi ve drenaj alanı dikkate alındığında heyelan set gölünün kararlı olduğunu göstermiştir. 0,00021'lik II değeri, rezervuar hacmi ile heyelan set hacmi arasındaki dengeyi göstermektedir. Bu değerde yine kararlı bir set gölü olduğunu sonucunu ortaya koymuştur. Son olarak DBI değerinin -4,12 olması set gövde yüksekliğinin ve rezervuar kapasitesinin heyelan setini kararlı halde devam ettiğini göstermektedir. Genel olarak, göl uzun bir süredir varlığını devam ettirmektedir ve özellikle drenaj sistemi üzerinde uygun çalışmalar yapılarak göl kontrol edildiğinde, gelecekte de istikrarlı olarak varlığını koruyacağı düşünülmektedir. Ancak Kuzey Anadolu Fay zonunun yakınındaki tektonik hareketler, bölgedeki jeomorfolojik süreçlerde oluşabilecek riskler gibi birçok farklı muhtemel risk açısından gözlem ve yeni araştırmaların yapılması ihtiyacının göz ardı edilmemesi gerekmektedir.

Published: March 2024

Ekonomik küreselleşme ticari ve finansal küreselleşme yoluyla yeni pazarlara erişimi kolaylaştırabilirken, rekabeti artırabilir ve yatırım maliyetlerini artırabilir. Ticari küreselleşme, uluslararası ticaretin artmasına ve ticaret engellerinin azalmasına yol açabilir. Finansal küreselleşme ise sermaye akışlarının serbestleşmesine ve uluslararası finansal piyasaların entegrasyonunu sağlayabilir. Vergi politikalarındaki değişiklikler, yatırımcıların kar marjlarını etkileyebilir ve yatırım yapma isteklerini azaltabilir veya artırabilir. Vergi yükü artışları, yatırımcıları caydırabilir ve yatırım özgürlüğündeki kısıtlamalar, yatırımların serbest akışını engelleyebilir. Yatırım özgürlüğünün azalması ise yabancı yatırımcılar için tercih edilmeyebilir. Bu faktörlerin dengeli bir şekilde yönetilmesi, doğrudan yabancı yatırımların sürdürülebilir ve istikrarlı bir şekilde artmasını sağlayabilir. Bu çalışmada 1995-2021 dönemi için BRICS-T ülkelerinde ekonomik küreselleşme, vergi yükü ve yatırım özgürlüğünün doğrudan yabancı yatırımlar üzerindeki etkisi incelenmektedir. Çalışma sonuçlarına göre; Brezilya, Hindistan ve BRICS-T ülkelerine ait panelde ekonomik küreselleşme doğrudan yabancı yatırımları artırmaktadır; Çin'de yatırım özgürlüğü doğrudan yabancı yatırımları artırmaktadır; vergi yükü Güney Afrika'da doğrudan yabancı yatırımları azaltırken Türkiye'de artırmaktadır. Genel olarak BRICS-T ülkelerinin, dış ticareti kolaylaştıran politikaları desteklemeleri önerilmektedir.
Using Environmentally Friendly Materials to Improve the Properties of the Drilling Fluid
Authors: Assi Amel Habeeb
Published: March 2024

This study presents a significant advancement in addressing the utilization of environmental additives to improve the properties of drilling mud. The current materials added to drilling fluids could cause a harmful effect on the environment and safety of individuals, highlighting the necessity for alternative additives. In this study, the potential use of orange peel powder (OPP) and Sidr leaf powder (SLP) as environmentally friendly additives to drilling fluid is evaluated. Laboratory tests were conducted to identify the impact of OPP and SLP on the drilling fluid properties. Different weights (1-20) % of OPP and SLP were utilized to prepare the drilling fluid. The results demonstrated that both OPP and SLP affected the rheological properties and filtration of the drilling mud. Notably, the density of the drilling fluid decreased significantly with the addition of crushed Sidr. Attributed to the composition of flavonoids and jujubogenin glycoside in the leaves, and citric acid in the orange peel. The specific weight of SLP and OPP (1.5 and 1.7 respectively) is considerably lower than that of bentonite (2.5), leading to a reduction in density. Sider leaves exhibited a high performance compared to orange peel, with the highest value of yield point, 10 min gel, pH observed at 20 gm of addition. The experimental findings demonstrate the impact of both materials, filtration, viscosity, and alkalinity, with Side leaves proving to be more in enhancing drilling fluid properties.

Published: March 2024

Surge and swab pressures are frequently produced during various stages of well construction, including casing running and tripping operations. Managing downhole pressure within the mud window is crucial for mitigating the risks associated with drilling operations including wellbore failure, lost circulation, kicks, and well control issues. The primary objectives of this study are to emphasize the theoretical foundation of surge and swab pressures, forecast the optimum pipe and casing tripping speeds, as well as identify the changes in surge and swab pressures (i.e., equivalent circulating density-ECD) for both open-ended and close-ended drill strings. To achieve these goals, a steady state surge and swab model was used to simulate a case study in the Rumaila oil field, located in Southern Iraq, by utilizing landmark-well plan software. The results of this study support the evidence that the string trip speed plays a substantial role in controlling the swab and surge pressures. It was found that pulling out the 5" drill string from the 12 1/4" open hole section drilled with a 9.51 ppg water-based mud at a speed of 10 sec/stand resulted in a swab ECD below the formation pore pressure against all formations, thus resulting in a kick. Moreover, it was found that the annular clearance had a significant impact on the surge and swab ECD whereas the surge ECD at the bit was bigger than that obtained at the previous hole casing shoe. For example, in our case study pulling speeds ranging from 10-190 sec/stand for the 9 5/8" casing could cause the swab ECD to be below the formation pore pressure gradient at total depth (TD), which is 9.23 ppg. While it was safe to run the same casing through the same interval within 55-190 sec/stand. Furthermore, the results emphasized high trip speeds ranging between 10-30 sec/stand, where for close-ended drill strings, greater surge ECD was observed compared to the open-ended ones. The surge ECD of a 5" close-ended drill string at 30 sec/stand (60 m/min) at bit was 9.92 ppg, while an open-ended string at the same speed was 9.9 ppg.

Published: March 2024

In the current study, the effect of the nonionic surfactant (span 80) on the emulsification of a mixture of kerosene as a petroleum-based organic solvent and span80 as a green diluent in the ratio 1:1 was investigated. NaOH was used as the internal phase, and the stability of the emulsion was tested. The potential for extracting phenol from aqueous solutions without the use of a carrier agent has been explored using Pickering emulsion liquid membrane. Additionally, the impacts of experimental parameters include homogenizer speed, mixing speed, emulsification time, Fe3O4-Span 80 ratios, NaOH concentration, and internal to membrane volume ratio (I/O) on extraction effectiveness and emulsion stability. The findings demonstrated that after 9 minutes of contact time and a minimum breaking percent of 0.745% under ideal circumstances, more than 96% of phenol could be recovered. In addition thermodynamic analysis reveals that the extraction process was an endothermic and spontaneous in nature and the overall mass transfer coefficient was 1.115 m/s. Membrane materials and nanoparticles were recycled four time in the extraction of phenol with approximately the same efficiency and no significant breakage percent..
Maximizing Production Profits: Optimizing Gas Lift Design in the Halfaya Oil Field
Authors: Ahmed Safwan Riyadh , Sadeq Dhifaf Jaafar
Published: March 2024

Gas lift is one of the most common artificial lift methods which is effectively utilized in the oil industry for enhancing production. However, proper gas allocation into wells can be challenging due to various limitations such as shortage in injected gas and economic considerations. Therefore, the current research is conducted to address the critical requirement to effectively distribute gas to maximize profits in the Halfaya Oil Field- Mishrif formation. Continuous gas lift is one of the most commonly used artificial lift methods. To enhance production rate, a sufficient amount of gas is injected into the production tubing at specific depths to reduce the liquid column pressure as each well has an optimal point for production in an oil reservoir. On the other hand, constraints of gas availability restrict achieving the optimal state of production. Such restrictions combined with economic limitations including high gas prices and compression costs, emphasized the necessity for optimal methodology to enhance oil production. Aside from the importance of the Halfaya oil field, there are limited relevant studies on artificial lifting methods specifically associated with the gas-lifting method used in this paper. Thus, the purpose of the current investigation is to propose a well-tested gas lifting design for oil production improvement. The approach combines the skill of the fmincon function built in MATLAB as an optimizer and the PIPESIM network model to create gas lift performance curves.  This resulted in an oil production rate of 18860 STB/d, with a gas lift rate of 9.42 mmscf/d. Establishing such a systematic optimization process can manage the challenges of gas allocation in the Halfaya Oil Field towards maximizing production rates and ultimately increasing net profits.

Published: March 2024

The scarcity of fresh water and its essential role in sustaining life on Earth have motivated researchers to seek new, low-cost, scalable technologies for water desalination. Therefore, the osmotically assisted reverse osmosis (OARO) membrane process presents an innovative approach to achieve moderate water recoveries from high salinity water without undergoing a phase change. This work aims to investigate the performance of hybrid RO-OARO systems with various designs and operational parameters on recovery and R%. The hybrid systems were evaluated for 60 minutes at feed concentrations of 3.98-5.54 g/l, applied pressures ranging from 3 to 7 bars, and different membrane types. The results showed that the flux of the hybrid system increased by increasing the pressure and decreased by increasing the feed concentration. The highest recovery value was obtained for the RO-OARO system at an RO pressure of 7 bar and an OARO unit at 3 bar for a 3.98 g/l feed concentration. In contrast, when the reverse osmosis pressure was fixed at 5 bar, and the pressure of the OARO unit increased by 2 bar, the recovery value exceeded by about 6%. Furthermore, the FilmTech membrane showed the highest recovery at 31.7%, while the highest R% was 94.55% for the AquaTec membrane. The RO-OARO-OARO system contributed to increasing both the recovery and rejection values by 11.4 and 2.1%, respectively, compared with the RO-OARO system. The experiments in this study revealed a slight increase in the feed concentration of the reverse osmosis unit, indicating the efficiency of the hybrid systems compared to traditional RO systems.

The burst pressure and fracture sites were also investigated. In addition, know how LPG cylinders are compliant with ISO 4706 requirements as per standard to get approval and acceptance. The tests were performed on three samples (C1, C2, and C3), and all the tests were according to the specification. Tensile testing was carried out at room temperature (23C°) as per ISO 6892-2016. Tensile test specimens with a gauge length of 50 mm were prepared from the sidewall of cylinders. The equipment used is built up around a 250 KN maximum capacity of (Instron Servo-Hydraulic Testing Machine Model 1332). At the same time, micro-hardness testing was carried out as per ASTM A384. Diamond indenter (pyramid) with a face angle of 136° was used. During testing (1kg) load was applied on the sample with a dwell time of 15 seconds. As for bending tests were carried out in accordance with ISO 7438 for all cylinders to evaluate their welding qualities. The results of microstructural characterization show that the carbon content for all samples averaged ~ 0.067 wt.% and manganese ~ 0.46 wt.% and the microstructure was largely ferritic. The tensile strength of the parent metal showed that LPG gas cylinders recorded high tensile strength of ~ 418 MPa on average, yield strength of ~ 291 MPa on average, a % elongation 26.6 (for parent metal), the tensile strength of ~ 449 MPa as average, yield strength of ~ 314 MPa as average, % elongation 32 (for weld metal) and hardness of ~ 143 (kg/mm2) as average by Vickers scale. Moreover, in the hydrostatic pressure test, the computer controlled electro-hydraulic servo pressure test machine was used. The results of the hydrostatic pressure test were as follows, pressure burst (BP) 103 bar, nominal hoop stress 528 MPa, volumetric expansion 25%, hydrostatic extend ratio 3.9%, sites of failure exist out of welding, and finally no fragmentation observed regarding to fracture types. All samples tested exhibited high resilience to crack propagation which showed ductile fracture after burst and tensile tests.

Published: March 2024

Coffee is the most essential drink today, aside from water, the high consumption of coffee and the byproducts of its soluble industries such as spent coffee grounds can have a negative effect on the environment as a source of toxic organic compounds. Therefore, caffeine removal from the spent coffee ground can be applied as a method to limit the effect of its production on the environment. The aim of this study is to determine the kinetics and thermodynamics parameters and develop models for both processes based on the process parameters by using traditional solid-liquid extraction and Ultrasound-assisted extraction methods. The processes were performed at a temperature range of 25 to 55 °C for traditional and ultrasound baths, and experimental time ranged from 5- 60 min. The results demonstrated that under the above conditions, the extraction process applies to the pseudo-first-order reaction, where the rate constant K value increases with temperature. The transition state parameters were also discussed where these parameters indicated that the system of the process exhibited an activated complex formation state resulting in a thermodynamically unfavorable process, and the thermodynamic parameters at the equilibrium state were also evaluated in terms of the obtained yield percentage. The results also showed that the ultrasound-assisted bath process showed a spontaneous behavior at temperatures of 45 °C and 55 °C with D°G of -1192.9703 and - 2725.25 J/mole. On the other hand, for the traditional method,  the extraction process was approaching a spontaneous behavior with the temperature increasing where at 25 °C the D°G value was 10379.944 J and at a temperature of 55 °C it reached 8004.26 J/mole.

Published: March 2024

The performance of a three-dimensional electrocoagulation process operated at a batch recirculation mode for treating petroleum refinery wastewater using aluminium as a sacrificial anode, stainless steel as a cathode, and granular activated carbon with metal impregnated carbon (GACMI (Al: Fe)) with mass ratio (2:1) as a third particle electrode was investigated. Effects of operating factors such as the applied voltage (15-30 v), flow rate (50-175 mL/min), pH (4-10), and GACMI dosage (5-10) g/L on the chemical oxygen demand removal were investigated. Using Box-Behnken design (BBD), a mathematical model relating the essential operational parameters to chemical oxygen demand (COD) reduction was constructed. Results showed that the effect of GACMI dosage on the efficiency of COD removal was the major one, where COD removal increased as GACMI dosage increased. However, increasing applied voltage would enhance the performance of the electrocoagulation reaction. Experimental chemical oxygen demand removal of 96.25 % was attained at the optimized conditions (applied voltage=27.7 v, flow rate=128 mL/min, pH=5.6, GACMI dosage= 8.7 g/L). BET-specific surface area, total pore volume, X-ray fluorescence (XRF), energy-dispersive X-ray spectroscopy (EDX), and scanning electron microscopy (SEM) were employed for the characterization of GACMI particle electrodes.

Published: March 2024

Increasing oil production from a reservoir can be achieved by decreasing the distance between the injector and the producer through a process known as infill drilling, which involves a pattern water flood. The main objective of this study is to provide a comprehensive overview of the optimal infill well location and the research and applications available to enhance the oil recovery factor, leading to increased economic profits. one effective empirical approach used in this study is based on decline curve analysis, which analyzes the production history of the well to determine the final economic recovery. Additionally, a numerical method that combines numerical simulation and optimization techniques has been proven to be successful in determining optimal infill drilling locations. The research results show that the volumetric computation of oil in place is a useful method for estimating the number of infill wells needed, but it does not consider heterogeneity and continuity. On the other hand, the numerical simulation and optimization techniques can quantify the remaining mobile oil post-infill drilling and establish optimal pattern configurations for maximum recovery at their centers.

Published: March 2024

Grammatophyllum stapeliiflorum, recognized as the melancholic orchid, represents one of the elusive orchid species facing the brink of extinction, thus exacerbating its rarity. Tissue culture technology becomes imperative for the propagation of this orchid species. This study aims to scrutinize the influence of different concentrations of the synthetic growth regulator thidiazuron (TDZ) on distinct basal media types, Murashige Skoog (MS) and Vacin and Went (VW), on the in vitro growth of G. stapeliiflorum orchids. Employing a complete randomized factorial design, the study entails two research factors: TDZ concentration with 4 treatment levels, A0 = 0 mg/L, A1 = 0.25 mg/L, A2 = 0.50 mg/L, and A3 = 0.75 mg/L, and the second factor being the media type, B1 = ½ MS and B2 = ½ VW. Findings indicate significant effects of MS and VW media on the percentage of viable explants, browning, globular forms, and shoots. Interaction between TDZ concentration and media type didn't yield significant effects on each experimental parameter. Treatment with 0.25 and 0.50 mg/L TDZ on ½ VW media demonstrated optimal results for explant growth percentage, browning, and explants in the globular phase, at 97.33%, 2.67%, and 2.67%, respectively. Moreover, treatment with 0.75 mg/L TDZ on ½ VW media resulted in the highest percentage of explant coloration. The combination of TDZ and media has shown the potential to enhance the production efficiency and conservation of this rare orchid species through tissue culture technology.

Composting serves as a pivotal strategy in waste management, alleviating the burden on final disposal sites while simultaneously providing valuable fertilizer for urban agriculture. This study aims to delineate the intricacies of the composting process and elucidate the characteristics of compost derived from recycling centers/compost houses in Surabaya City, Indonesia. Employing a qualitative descriptive approach, this research scrutinized the composting process by delving into the origins of raw materials, procedural stages, and the chemical composition of the resultant compost. The composting materials encompassed household waste, market refuse, and fall foliage. Notably, composting occurred within an open aerobic system devoid of bio-activators. Chemical analysis revealed: C/N ratio (17.10 - 19.60), C-total (17.65% - 18.10%), N-total (0.95% - 1.12%), P2O5 (0.35% - 0.51%), K2O (0.39% - 0.41%), Cu (1.65 ppm - 2.01 ppm), Pb (2.05 ppm - 3.11 ppm), Cd (0.11 ppm - 0.24 ppm), and Zn (1.02 ppm - 1.14 ppm). Physically, the compost manifested as a dark brown substance, exhibiting a soil-like softness attributable to grinding, with temperatures oscillating between 41.90 to 55.00°C. Visually, the compost appeared mature and primed for utilization based on color and texture criteria; however, indicators such as C/N ratio and temperature suggest an immature state rendering the compost unsuitable for immediate planting. To ensure optimal maturity conducive to plant growth, it is recommended that users store the compost for a minimum of one month before application, thereby fostering its maturation process.
