Authors: Dogan Bekir , Ozbey Mustafa , Namli Lutfu , Aybek Unsal
Published: September 2023

In the study, a numerical simulation of the sliding properties of the rough and smooth surfaces with micro-structure was made. The simulation of shear flow in the micro-channel was performed with ANSYS FLUENT software. The 3-D and two-phase flow is simulated by choosing the volume of fluid model. In CFD analysis, water and air consist of two immiscible phases. In the calculations, if water is the first fluid and air is the second fluid, adjustments are made. At the beginning of the analysis, the channel was considered to be completely filled with air and the effect of gravity was ignored during the calculation. Water and air are considered Newtonian and incompressible fluids. In addition, laminar flow and steady-state calculations are made. It was found that the decrease in pressure drop increased with increasing distance between asperities (no-shear fraction). In the simulation results, approximately 14% of the velocity in the micro-channel axis was measured at the interface. The main purpose of this study is to evaluate the applicability of the volume of fluid model in a hydrophobic micro-channel flow designed in 3-D using ANSYS Fluent CFD software.

Published: September 2023

This study investigates heat transfer phenomena in a building envelope in
Bechar, Southwest Algeria, under arid climatic conditions. The
meteorological station Energarid provides precise recordings of solar
radiation and outdoor temperature. A calibrated model is used to analyze
diurnal temperature variations. Wall temperatures exposed to solar radiation
are estimated using recorded data. The heating power requirements of the
building envelope are determined through a thermal balance approach based on
the regulatory technical document from the National Center for Building
Studies and Integrated Research. Simulation results demonstrate favorable
conditions for achieving thermal comfort, with elevated air temperatures and
velocities at the outlet. Incorporating solar energy considerations into
architectural design, such as double facades, south-facing orientations, and
glazed surfaces, is crucial. These findings highlight significant
energy-saving potential, particularly in the Bechar region.

This study explores the principle of producing cold through heat absorption
at a temperature lower than ambient temperature, which requires the use of
an endothermic mechanism. Specifically, the study focuses on evaluating
multiple thermoelectric coolers using aluminum water heat exchangers as a
means of validating a proposed correlation through a series of experiments.
The system utilizes water as a coolant and a thermoelectric cooler coupled
with a heatsink to cool it. The cooling power of the system is controlled by
adjusting the temperatures of the hot and cold heatsinks and the coolant
flow through the heat exchanger based on governing equations. In addition to
assessing the cold-side temperature, the research also investigates the
system COP of the thermoelectric system. The results indicate that a
thermoelectric cooler with a lower thermal resistance is more effective at
cooling and can achieve a lower cold-side temperature. Conversely, a
cold-side heatsink with a higher thermal resistance provides lower cooling
power. Two experiments were conducted to acquire comprehensive data on the
thermoelectric devices, and the obtained results and experience were used to
categorize the utilization of the Peltier model. The first experiment
achieved an 84% success rate, while the second experiment achieved a rate of
around 97- 95%, highlighting the potential for further experimentation with
alternative configurations.
Managers’ Stock Price Incentives and Earnings Management Using Tax Expense
Authors: Beardsley Erik L. , Kara Mehmet C. , Weaver Connie D.
Published: September 2023

This study examines the association between stock price incentives (portfolio delta) and earnings management using tax expense, as well as whether this association varies with opportunities to manage earnings. Prior research suggests stock price incentives provide a positive “reward effect” and a negative “risk effect,” causing managers to trade off these countervailing effects when managing earnings. We posit that greater opportunities to manage earnings alter the risk-reward tradeoff related to portfolio delta, potentially changing the association between stock price incentives and earnings management. We do not find a significant association between stock price incentives and earnings management using tax expense on average. However, the association is positive and significant when tax-related earnings management opportunities are sufficiently high, consistent with opportunities mitigating the risk effect of delta. Collectively, our results suggest that managers respond to stock price incentives differently depending on their opportunity sets.

Influence of ring-shaped beam profiles on spatter characteristics in laser-based powder bed fusion of metals
Authors: Grünewald Jonas , Reimann Jan , Wudy Katrin
Published: September 2023

Despite the maturity of laser-based powder bed fusion of metals (PBF-LB/M), some barriers prevent the manufacturing process from fully being established in the industry. One drawback is spatter formation, which is disadvantageous to PBF-LB/M for three main reasons. First, adhering spatter can initiate coater collision, resulting in process failure. Second, large adhering spatter may cause lack-of-fusion defects as they require more energy to remelt sufficiently compared to unprocessed powder. Furthermore, big nonadhering spatter cannot be recycled as powder. The recycling of small spatter particles potentially results in degraded material properties. Ring-shaped beam profiles have been established for deep penetration welding to reduce spatter formation. Investigations on ring-shaped beam profiles in PBF-LB/M focus on improving productivity and process robustness. Qualitative spatter reduction in PBF-LB/M using ring-shaped beam profiles has also been reported. This publication quantitatively examines the influence of ring-shaped beam profiles on spatter formation in PBF-LB/M. Image processing algorithms of on-axis high-speed images are utilized for spatter detection and tracking. A self-developed spatter segmentation is used to determine the spatter size. A Laplacian of Gaussian filter is combined with a Kalman tracker to count and track the spatter. The results show that spatter formation is highly influenced by the beam profile and the chosen process parameters. Considering the melt track width, ring-shaped beam profiles could reduce the number of spatter per fused area. High numbers of spatter are generated when parameter sets result in balling. Moreover, spatter velocity is primarily dependent on the introduced dimensionless enthalpy.
Environmental and Biotechnological Perspectives on Hydrolases
Authors: B Deivasigamani
Published: September 2023

Micro-organisms are able to survive in high salt concentrations because they have developed diverse biochemical, structural and physiological modifications, allowing the catalytic synthesis of proteins with interesting physicochemical and structural properties. When opposed to chemical catalysts, enzymes are protein-based catalysts that offer significant advantages. Enzymes are viewed as a greener alternative to conventional chemical catalysis in industrial processes since they are biodegradable, reusable, and do not produce excessive waste products. Enzymes are useful biological instruments for bioremediation that are both environmentally acceptable and bio based. An essential class of enzymes called hydrolases encourages the depolymerisation of macromolecules, which is crucial for the metabolism of nutrients. They have properties that make them desirable for biotechnological applications, in particular for environment protection, where hydrolaseproducing organisms can be used in the removal of contaminants through a process known as bioremediation. They are highly effective catalysts, frequently secreted into the surrounding medium, and the majority do not require cofactors. Hydrolases present an opportunity to investigate the conformational variation that underlies the wide range of biological functions that these enzymes perform because they are the most numerous and diverse class of enzymes. The best choice for eliminating pollutants from the environment may be microbial hydrolases. All facets of life contain these enzymes, which are crucial for key biological activities like the breakdown of cellulosic biomass, viral pathogenesis, antibacterial defence, and typical cellular functioning. The fact that certain lysosomal storage illnesses have been linked to deficits in these enzymes, as well as the potential industrial uses of highly effective glycoside hydrolases. The isolation of active enzymes against particular pollutants comes from microorganisms that have been exposed to contaminated locations and those contaminants specifically. For the bioremediation of contaminants, several enzymes extracted from various species have been utilised. A viable approach to finding more effective and affordable instruments for the clean-up of contaminants would be to identify novel enzymes and new subtypes with specified physicochemical properties.

We currently live in a world where the depletion of resources is beyond our control. The demand for achieving sustainable development, both financially and ecologically, is communicated effectively and unambiguously. As a result, current and future generations must guarantee that all resources are maintained, fully utilized, and responsibly managed. Waste generation has always been a component of humanity’s quest for progress, whether in social or economic activity. The general meaning of “waste” is useless or in other words futile but nowadays waste is useful to create wealth and employment also but in the present scenario handling and treatment of “waste” is a big challenge. There is a lot of technology around us which solves the handling and treatment of waste as well as these methods creates wealth also. Plastics have become an integral and unmistakable part of our daily lives. Because of its high tensile strength, durability, lightweight, high elasticity, resistance to corrosion, and ease of transport, plastic is used to make a wide range of products, including carry bags, pet bottles, pouches, electric switches, computer accessories, automobile accessories, and many more.

gg4 Pseudo tumors Mimicking Urologic Malignancies: Comprehensive Review and Management of a Rare Infiltrative Upper Tract Lesion
Authors: Kern Sean Q
Published: September 2023

Objectives: Immune-mediated fibroinflammatory conditions are known to affect multiple organ systems, as seen in the IgG-4 related disease. While tubulointerstitial nephritis and membranous glomerulonephritis are the more common intrinsic renal diseases, IgG-4 mediated disease can mimick urologic malignancies and can pose a significant management dilemma. Our goal is to understand how to better diagnose, exclude malignancy, and preserve renal function in a rare Urologic disease. Materials and Methods: A review of current literature was obtained to provide additional insight and understanding on this rarely observed Urologic disease. In discussing the case presented, a pertinent clinical history, physical exam, and review of cross-sectional imaging is presented. Immunohistochemical analysis of the specimen was thoroughly performed with expert analysis by our consulting pathologist. Results: Very rare reports of renal, ureteral, pelvic, or scrotal IgG4 mediated pseudotumors have been published. In the absence of pathologic tissue analysis of biopsy samples, the diagnosis of this rare disease can be significantly challenging. In our presentation, a male patient was noted to have a 7cm mass replacing the left renal sinus and causing moderate left hydronephrosis. Initial concern was for upper tract urothelial cell carcinoma. However, left ureteropyeloscopy demonstrated normal left renal and ureteral architecture and excisional biopsy of a PET avid left cervical lymph node was performed however pathologic diagnosis was not able to be confirmed. This led to a management dilemma due to the progressing mass size, worsening renal drainage, and symptoms. The patient opted for surgical excision. Final pathology from a left radical nephrectomy was significant for an IgG-4 related inflammatory pseudotumor. Conclusions: IgG-4 related diseases are known to represent a systemic disease that leads to lymphoplasmacystic inflammation and fibrosis within the affected tissues. At this time, there is no standardized method for the diagnosis and treatment of patients with retroperitoneal involvement. Additional research is needed to identify improved diagnostic modalities, the role of immunosuppressive therapy, and the surgical management in this disease process.

Twin to Twin Transfusion Syndrome in Discordance Twins: Diagnostic and Management Approach
Authors: Winata I Gde Sastra , Setiawan William Alexander , Dyatmika I Kadek Wahyu Putra , Rastika I Gede Agus , Arjunan Shaalini
Published: September 2023

Twin to twin tranfusion syndrome (TTTS) is a rare condition that affects the identical twin pregnancy or other multiples. TTTS occurs when there is an imbalance in blood flow between fetuses who share one placenta. This condition can cause one fetus to be dominant among other fetuses or is called discordant twins. The cause of discordant twins is still unclear. But one of the causes is Twin-to-Twin Tranfusion Syndrome. The incidence of discordant twin pregnancies is around 15-29% of total pregnancies. The chance of developing TTTS is estimated to be around 10-15% of monochorionic diamniotic. TTTS is diagnosed by ultrasonography with measuring the single deepest pocket (SDP). TTTS can be treated by fetoscopy laser ablation. The aim of this treatment is to close the connection of blood vessels. There are alternative treatments such as amnioreduction, selective fetal reduction, or termination of pregnancy.

Published: September 2023

The amniotic membrane is a layer that directly covers the amniotic cavity derived from trophoblast cells with various types of pluripotent cells so that it has clinical potential. This membrane is essential for intrauterine fetal growth and development. The amniotic membrane has been widely studied to have various functions, one of which is in the process of wound healing, both acute and chronic. One type of acute wound that begins to use the amniotic membrane as a dressing material is a cesarean section wound.  In cesarean section, there is an acute wound due to the incision of the abdominal wall and uterus. The process of wound healing, especially in the epithelial part, is the same as other acute wound healing, which consists of the process of migration, proliferation and cross-linking between cells in the epithelium. In general, the amniotic membrane has clinical potential, especially in wound healing. This relates to the various substrates and the molecules contained therein. In some clinical studies also found a positive effect on wound healing. However, specifically discussing its clinical effectiveness in caesarean section wounds is still limited. Therefore, in this literature, we will discuss the use of the amniotic membranes in wound healing for cesarean sections.
Emergency Department Evaluation of Priapism: Etiology and Consultation
Authors: Fiesseler Frederick , Riggs Renee , Salo Dave , DeLong Claire , Walsh Brian
Published: September 2023

Introduction: Priapism is a time-critical condition requiring immediate evaluation and management to avoid significant sequela. Management of this condition is significantly variable, dependent upon the underlying cause, and often instituted by a consultant rather than the treating emergency physician.
Objectives: To determine etiologic factors contributing to priapism treatment and determine if treatments initiated in the emergency department (ED) contribute to an improved disposition metric.
Methods: We conducted a multi-center, retrospective study of patients with priapism caused by multiple different etiologies. Study subjected were located at 15 hospitals by chart review and conducted a computer-assisted chart review to locate patients with priapism for each hospital over a 2-year period.
Results: We evaluated 236 patients during the study period; 8 excluded for chart unavailable and 6 with non-priapism diagnosis on review. Median age was 39 years (IQR 22-52). Pediatrics, defined as less than 21 years of age, comprised 4% of patients (N=9). Overall, 85% (N=188) were discharged. Erectile dysfunction medications (EDM) were the most common identifiable cause; involving 23% (N=52). The remaining were sickle cell 20% (N=45), antipsychotic medications 14% (N=30), cocaine 2% (N=4), the remainder without an identifiable etiology. Overall, intrapenile procedures occurred in 56% (N=125) of patients. EDM was associated with significantly less intrapenile procedures compared to other etiologies, 15% (N=58) (p = 0.009), and also had a 2% (N=1) admission rate, significantly less compared to other etiologies (p=0.009). Further, consulting urology did not significantly increase mean length of stay, with difference of 19 minutes (p=0.64) when compared to ED intervention alone.
Conclusion: Priapism as a result of EDM, the most frequent etiology, was associated with less frequent emergent intrapenile procedures and significantly less admissions and urology consultation does not significantly lengthen disposition times.

The COVID-19 pandemic that has hit the world, including Indonesia, has had a crucial influence on the tourism industry. It is undeniable that the tourism industry in Indonesia seems to be in suspended animation due to unpreparedness for this disaster. From the supply side, tourism entrepreneurs are overwhelmed because of the absence of visits due to flight closures, travel minimization, and strict rules regarding the closure of tourist attractions during 2019. From the demand side, the community's need for tourism remains high, interest in traveling is even greater after one year "at home". In mid-2020 when tourism policies began to be relaxed, there was a revival of this industry's revival. There has been a change in tourist travel patterns during this pandemic, not just looking for beautiful tourist attractions, but also safe areas. The research that has been done shows that the pattern of tourist visits changes, there is an adaptation to the pandemic conditions. In-depth interviews were conducted on informants to obtain accurate data, tourists and tourist attraction managers were key informants. Some of the changes include: use of vehicles, selection of locations that offer health protocols, and expenses

The integration of geological heritage conservation into a regional sustainable economic and cultural development strategy is a general objective of geoparks. A geopark is an area that contains one or more sites of scientific importance not only from a geological point of view, but also from the point of view of its archaeological, economic or cultural specificity of European significance. The main objective of the paper is to present knowledge review and option for the development and strengthening of the role of geodiversity in tourism through the proposal of inclusion of the Geopark Gemer among the Geoparks of Slovakia. In the Gemer-Malohont region, there are 69 significant geological sites, which are protected under Act No. 543/2002 Coll., 5th or 4th level of protection, or are declared under the UNESCO Convention concerning the Protection of the World Cultural and Natural Heritage. There are 1,444 old mine workings and 42 protected deposit areas in the territory. There are also numerous caves, scrapes, scrape fields, sinkholes, karst plots, karst lakes, cave openings, karst vents, etc., a total of 207 of them have been recorded in the area. Based on these findings, we can confirm that the Gemer-Malohont region has the potential for geotourism development. The designation of Geopark Gemer would ensure the promotion and protection of the region's geological and cultural heritage.

Being able to put oneself in another's situation is truly a mastery skill that builds a manager's personality, team spirit and mutual trust. The aim of the paper is to declare the real importance of an empathy in a managerial work, as well as to present the results of empathy quotient on a sample of Slovak managers. For the examining, we used the Baron-Cohen and Wheelwright self-assessment test of empathy on a sample of 707 Slovak managers. Through our research, we conclude that Slovak managers have an above-average level of empathy. These positive findings opens up space for its implementation in every day work and also to reevaluate value preferences by knowing what makes a real sense. Secondary and primary survey results declare the fact that the right amount of empathy is not a sign of weakness, but of a person's greatness.
Reading The Book of Jonah through the Eco-Spiritual Perspective
Authors: Liew Hew Yan , Seach Jin Beng , Pathinathan Santini
Published: September 2023

Whether one chooses to acknowledge or disregard its significance, nature has always been part of us. In an anthropogenic era, the dire state of the environment has made it an increasingly concerning topic of discussion among us. Nature has been extensively examined in numerous scholarly discussions ranging from secular to religious perspectives. This paper examines how nature plays a crucial role in helping us understand the relationship between God and humans, as portrayed in the Bible. The Bible being a religious text exists with very specific purposes. That being said, elements of nature were also used very specifically in the Bible. Most presently available scholarly research focuses on reading the significance of nature elements from religious perspectives. However, this research employs the eco-spirituality theory to examine the book of Jonah from the Bible to determine the relationship between Jonah, God, and nature. Through this secular perspective, the aim is to show that elements of nature have been carefully woven into narratives to signify various meanings. Furthermore, this research aims to identify how God communicates with humans through nature, which eventually helps to establish various forms of relationships between humans and nature. Through these newly formed relationships, we can understand the authority of a Creator and the consequences of obedience and submission. All these highlight the importance of co-existence between humans and nature, and examining the Bible through the lens of eco-spirituality perpetuates the relevance of the Bible to 21st-century readers.
A formação didático-pedagógica de professores do ensino jurídico: análise sobre as percepções de docentes a respeito do estágio docente vivenciado no âmbito da pós-graduação stricto sensu em Direito
Authors: Tiroli Luiz Gustavo , De Jesus Santos Adriana Regina
Published: September 2023

A formação didático-pedagógica de professores para o ensino jurídico é um desafio da área. Conforme o artigo 66, da Lei de Diretrizes e Bases da Educação Nacional (LDB), compete, prioritariamente, aos cursos de mestrado e doutorado esse processo formativo. Todavia, o foco desses cursos é a pesquisa, sendo poucas as estratégias voltadas à formação docente, entre essas, o estágio em docência. Assim, questiona-se: de que maneira os egressos dos cursos de mestrado e doutorado em Direito têm percebido a formação didático-pedagógica ofertada a partir do estágio docente e, consequentemente, suas repercussões para a formação de professores para o ensino jurídico? O objetivo é caracterizar as percepções e desvelar os significados que os docentes do ensino jurídico construíram em relação ao estágio docente vivenciado durante sua formação nos cursos de mestrado e doutorado em Direito, a fim de discutir a formação didático-pedagógica dos professores do ensino jurídico. A pesquisa bibliográfica e de campo, o tratamento qualitativo dos dados e a análise de conteúdo foram os encaminhamentos metodológicos da investigação. Os dados foram coletados mediante entrevista com 90 professores egressos dos cursos de mestrado ou doutorado em Direito, no estado do Paraná, entre o período de 2017 a 2020. Nas considerações finais, verificou-se a prevalência da percepção do estágio como uma etapa burocrático-formal (31%) ou espaço de representações de modelos e antimodelos (18%). Constatou-se, também, a presença de uma concepção de estágio docente como etapa formativa intencional (9%), um processo crítico e transformador da prática docente.

Introduction: Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity, mortality, and healthcare costs worldwide. Lung cancer is the second most common cancer and is the leading cause of cancer mortality, accounting for almost 25% of all cancer deaths. This study aims to investigate the prevalence of COPD in patients with lung cancer (LC).

Materials and Methods: This is a cross-sectional observational study. Consecutive patients with suspected LC in a respiratory clinic were studied. The method of verification of the lung abnormalities (fibrobronchoscopy and/or transthoracic biopsy) was performed. Postbronchodilator spirometry was performed. An FEV1/FVC ratio < 0.7 was diagnostic for the presence of COPD. The association between the presence of COPD and LC with other routine tests (laboratory tests, blood gas analysis, CT) was also analyzed.

Results: A total of 65 patients with verified LC were included. 48.4% of the LC patients in this study had COPD. There was no significant difference in the prevalence of COPD in the different subgroups of non-small cell cancer: unspecified non-small cell cancer – 62.5%, squamous cell cancer – 50%, adenocarcinoma – 45.8% (p = 0.33). Patients with COPD and LC had lower FEV1 (56.9 vs. 70.5%, p = 0.01) but not FVC (71.6 vs. 74.6%, p = 0.67). The presence of COPD in LC patients was associated with lower leukocytes (8.8 vs. 11.3 x109, p = 0.018). Squamous cell cancer was associated with a higher number of leukocytes compared to adenocarcinoma (11.0 vs. 8.4 x109, p = 0.026), although smoking showed no clear association with histology.

Conclusion: Nearly half (48.4%) of the patients with LC also had COPD.
Esophageal Tumor Length – An Underestimated Predictor of Survival After Esophageal Cancer Resection

Published: September 2023

Introduction. Esophageal cancer is one of the most aggressive visceral tumors with increasing frequency and poor prognosis. Differences in survival between patients in the same clinical tumor stage necessitate searching for additional prognostic markers to help identify patients at high risk of recurrence, metastasis or death. The aim of the study was to assess prognostic significance of tumor length on survival after esophageal cancer resection in patients operated at a center for esophageal surgery.

Materials and methods. This was a prospective cohort study including 117 patients who had undergone surgical resection with curative intent for esophageal cancer. The study was conducted at the First Surgical Clinic of UMHATEM “N. I. Pirogov”, Sofia, Bulgaria. The inclusion period was between 1st January 2013 and 31st December 2015 and the patients were followed – up until 10 April 2022. The patients were divided into two groups according to the tumor length – under 3 cm (group 1) and over 3 cm (group 2). The prognostic impact of tumor length on survival was analyzed with Cox regression analysis. Overall survival was presented by the Kaplan-Meier method with log-rank tests.

Results. The 5-year survival rate was 11.1%. Median survival rate was 26.0 months (95% CI 18.3-33.7 months) for the patients in the first group and 13.0 months (95% CI 10.3-15.7 months) for the second group patients. Tumor length over 3 cm was a negative prognostic factor (HR 2.36 95% CI 1.06-5.25; p = 0,03).

Conclusion. Length of esophageal cancer is a powerful independent predictor of survival in addition to the TNM stage.

Cavitating Venturi as a Mass Flow Controller in a Deep Throttling Liquid Rocket Engine
Authors: Sekrecki Michał
Published: September 2023

The most common solutions for rocket engines are the single operation point (thrust level) units. Oxidiser and fuel mass flow rates and the oxidiser-to-fuel mass flow rate ratio (OFR) are some of the determinants of the thrust level. Based on these, planetary ascent and descent; space rendezvous; orbital manoeuvring, including orientation and stabilisation in space; hovering, hazard avoidance during planetary landing; and ballistic missile trajectory control propulsion systems could use throttleable liquid engines. Several engine throttling methods, such as supply pressure variation and variable injector area, can be applied. Among others, a cavitating venturi propellant regulatory valve is one of the most promising throttling method. This type of valve can provide steady mass flow, despite the downstream pressure disturbance (i.e. from the combustion chamber), which sustains a stable engine thrust as the mass flow is kept. The article presents the valve sizing method, design and prototype test results of the cavitating venturi valve that has potential for utilisation in a deep throttling rocket engine. Mass flow stability and repeatability are presented for valve operating points in the 10%–110% nominal mass flow range. Valve design optimisation, based on CFD, to sustain cavitation for a higher downstream-to-upstream pressure ratio is shown.
Die Vielfalt der Emergenz - Vom Atom bis zur Natur des Menschen
Authors: Waldvogel Francis
Published: September 2023

Nehmen wir die Welt, die uns umgibt, so wahr, wie sie ist? Die Welt erscheint uns wohl als eine Ansammlung von Objekten – winzig kleine und unendlich grosse –, aber zwischen diesen Objekten gibt es ständig Wechselwirkungen. Die Biene saugt den Nektar aus der Blume und besamt sie gleichzeitig, die Atome tauschen Elektronen aus und schaffen dadurch chemische Verbindungen, Lebewesen sind in ständiger Wechselwirkung mit ihrem Umfeld, mit Worten tauschen wir Menschen uns über unsere Gedanken und Gefühle aus.
Um diese Wechselwirkungen, die zu neuen Emergenzen, führen – etwa zu Leben, Gemeinschaften, Altruismus –, geht es dem Autor. Denn in diesen emergenten Phänomenen wurzelt die Komplexität des Universums, dem wir angehören.
Hayvancılık işletmelerinde atmosferik amonyak gazının AERMOD ile modellenmesi
Authors: MUTLU Atilla
Published: September 2023

Amonyak (NH3) emisyonları, atmosferde insan sağlığı ve çevre üzerinde önemli etkileri olabilecek PM2.5 oluşumunda çok önemli bir rol oynamaktadır. Bu çalışmada, daha önce bir süt sığırcılığı tesisinden atmosfere yayılan NH3 gazı emisyon değerleri kullanılarak, işletme için NH3 gazının saatlik ve günlük dağılımları modellenmiştir. İşletmeden salınan NH3 gazı AERMOD (The American Meteorological Society/Environmental Protection Agency Regulatory Model) ile modellenmiştir. AERMOD günümüzde endüstriyel alanlarla birlikte hayvancılık tesislerinden salınan hava kirleticilerinin etkilerini belirlemek için kullanılan USEPA onaylı bir hava kalitesi dağılım modelidir. Çalışma alanı, yaklaşık 2200 baş hayvana sahip ticari bir süt sığırı işletmesidir. Modelleme sonucunda, işletmeden en yakın yerleşim alanına olan saatlik NH3 imisyon yükü yaklaşık 19 µg/m3 ve günlük NH3 gazı imisyon etkisi yaklaşık 4 µg/m3 olarak tahmin edilmiştir. Bu değerlerin hem Amerikan ve hem de Avrupa hava kalitesi yasal sınır değerlerinin oldukça altında kaldığı tespit edilmiştir.
