LOGIC Mobile Drilling Rigs Standard Form Contract: An Analysis of its Provisions on Liability, Risk and Insurance
Authors:   , Taha Towfik
Published: December 2022

While the title “offshore drilling contract” might indicate the legal scope of the offshore drilling Contractor’s obligations, the true level of the contractual risk might not be determined unless a reference is made to a specific format, this is because the obligations of the parties under English law are identified by the court in accordance with the wording of the relevant contract. Moreover, the general consideration of case law on the question of day rate drilling contracts, without making reference to a specific agreement, could be to some extent an illusory attempt to draw a complete conclusion. Bearing this in mind, the aim of this thesis is to evaluate the legal scope of the offshore drilling contract by utilising the LOGIC Mobil Drilling Rigs Standard Contract (LMDRC) under English Law as a base for this research. This study will approach the day rate offshore drilling contract in accordance with the structure of LMDRC with a main focus on the substantive provisions usually utilised to reallocate the risks between the parties. Whilst dissecting the standard form, comparing them with the contractual industry practice, and suggesting the alternatives when they are required. Consideration will be given to the nature of drilling operation, legislative development, caselaw and the contractual solutions which might be adopted in other jurisdictions.

Published: December 2022

The object of the research is an agrophotovoltaic system. An analysis of the operating conditions of one of the existing solar power plants was performed and limitations of electricity generation due to its excess in the power system or due to work mode restrictions both under the normal state of the power grid and under individual emergency or repair modes were identified. This leads to an underproduction of electricity and a decrease in the efficiency of using the installed capacity of the solar power plant (SPP). Therefore, it was proposed to introduce an agrophotovoltaic system, which allows for more efficient use of land resources, it also allows us to increase the yield of agricultural crops that can be planted on the territory of a solar power plant, to eliminate restrictions on the delivery of generated power to the power grid through its direct consumption at the site of the SPP. The feasibility study of the project of an agrophotovoltaic system based on the existing power plant shows that its payback period will not exceed 3 years, and the profit for the 5th year of exploitation of such a system will be up to € 279409.
Development of a Mathematical Model for Obtaining Energy Characteristics of the Turbine Unit with the K-325-23.5 Steam Turbine
Authors:   Lviv Polytechnic National University, Kravets Taras , Riabokon Hryhorii ,   LVIVORGRES PJSC
Published: December 2022

The results of mathematical modelling of the turbine unit with the K-325-23.5 steam turbine are presented. The mathematical model of the turbine is a system of equations for the components of the heat-balance diagram and the main dependencies of its operating characteristics obtained through the thermal full-scale tests. The developed mathematical model allows adjusting the results of the full-scale tests, creating normative characteristics and conducting research of the intermediate modes of the turbine operation. It is suggested to obtain correction curves for the main parameters of the turbine unit by conducting a simulation experiment on a mathematical model of the turbine instead of carrying out real tests. The correction is done by a complete recalculation of the turbine and its thermal cycle, taking into account the characteristics of the components of the turbine unit and the conditions of its operation during the test. As a result, the main energy characteristics under different operating conditions have been obtained, in particular, correction curves of the main steam consumption and specific heat consumption for the deviation of the initial steam parameters and changes in the heat-balance diagram were built.
Optimization of Thermal Subsystem of Thermo Transducers for Measuring the Temperature of Gas Flows
Authors:   Lviv Polytechnic National University, Fedynets Vasyl , Vasylkivskyi Ihor
Published: December 2022

The error of measuring the temperature of gas flows by contact methods consists of two main components: 1) the error that occurs in the process of measuring the physical quantity into which the temperature is converted (the error of the measuring means); 2) errors arising in the process of converting the temperature into a measured physical value using a thermo transducer. This component of the error is completely thermal in nature and is determined by the conditions of the thermal balance between the studied gas flow and the thermo transducer and has the greatest impact on the overall measurement error. It is determined by the combined action of the following factors: heat transfer due to radiation to or from the thermo transducer; heat removal from thermo transducer due to thermal conductivity; by converting part of the kinetic energy of the gas flow into thermal energy in the wall layer surrounding the thermo transducer; by convective transfer of heat from the wall layer to the sensitive element of the thermo transducer. Note also that if the temperature of the gas flow is non-stationary, then due to the thermo transducer's own heat capacity, it does not have time to register the time-varying temperature of the flow. Due to this, a dynamic component of the measurement error arises during the measurement of non-stationary temperatures. The article investigates the component error determined by the conditions of heat exchange between the gas flow and the thermo transducer.

Published: December 2022

Background: Vitamin D deficiency (VDD) is the one of the major public health problem affecting approximately one billion people all over the world. In recent years, the relationship of allergic diseases with a low concentration of vitamin D has been studied worldwide. An association has been found between small count of serum vitamin D and the development of immune disorders. Patients with allergic disorders and, in particular, with respiratory allergy are susceptible for VDD.

Objective: The study was aimed to assess the levels of serum 25-hydroxyvitamin D (25(OH)D) and their associations with the severity of seasonal allergic rhinitis in the Karaganda region (Kazakhstan).

Material and methods: This cross-sectional study included 416 patients with seasonal allergic rhinitis aged 18-65 years (mean age 39±8 years), 267 of whom were females. VDD was defined as serum concentrations of 25(OH)D below 20 ng/ml.

Results: The median concentration of 25(OH)D in blood serum was below the reference threshold (20 ng/ml) and amounted to 16.1 ng/ml. 75% of patients with seasonal allergic rhinitis had VDD and this was common in all age categories. VDD was more prevalent in female patients (82.8%) as compared with the male patients (61.1%) (p<0,01). Of interest is the fact that low serum 25(OH)D concentration correlated with the severity of symptoms (r =-0.94 and r =-0.67).

Conclusion: According to our study, the significant part of patients with allergic rhinitis residing in Karaganda region (Kazakhstan) had deficient status of 25(OH)D and this correlated with the severity of symptoms.

Authors: KATİPOĞLU Okan Mert
Published: December 2022

Accurate estimation of streamflow has an important role in water resources management, disaster preparedness and early warning, reservoir operation, and sizing of water structures. In this study, Extreme gradient boosting (XGBoost) and K-Nearest Neighbours (KNN) algorithms are used for the estimation of streamflow. In order to reveal the appropriate model, the raw model and models with optimized parameters were evaluated while the models were being built. In the setup of the models, various training test rates were also tried, and it was investigated which data division showed more effective results. For this purpose, the data were divided into ratios such as 60-40, 70-30, 80-20, and 90-10, respectively, and the model results were compared. Various statistical indicators such as Root Mean Square Error (RMSE), Mean Absolute Error (MAE), and Coefficient of Determination (R2) were used when comparing the models. As a result of the analysis, it was determined that the most suitable model for monthly streamflow estimation was obtained by using the optimized Xgboost algorithm and 60-40% data division. The obtained outputs constitute a vital resource for decision-makers regarding water resources planning and flood and drought management.

Published: December 2022

Su gücü(Hydropower) endüstrisinde su kaynaklarının gelişimi bakımından son 60 yılda özellikle son 30 yılda büyük ilerleme ve yenilikler ortaya çıkmış, buna paralel dünyada büyük hidroelektrik projeler inşa edilmiştir. Hidroelektrik güç üretilen büyük ve kompleks yapıların karakteristikleri başlıca; baraj tasarım yükü yüksekliği, büyük deşarj, birim genişlikteki deşarj kapasitesi ve karmaşık jeolojik koşullardır. Üretilen güç miktarı onlarca veya yüzlerce gigawatt kadar yüksek olabilen bu derece yüksek güç üreten potansiyel enerjiyi dağıtmak, sönümlemek baraj mühendisliğinin elbette zor olan konularındandır. Dolayısıyla baraj mühendisliğinin araştırma konularından olan barajların deşarj yapılarının hidrolik karakteristikleri ve ortaya çıkan enerjinin güvenli ve ekonomik olarak dağıtımının sağlanması hususu dikkate alındığında etkin bir proje tasarımı için yapılacak fiziksel modelleme, prototip deneyleri ve sayısal modelleme sonuçlarının birlikte değerlendirilmesi gerekmektedir. Bu çalışmada yapılan fiziksel model çalışmalarıyla belirlenen deşarj yapılarındaki hidrolik karakteristikler ve enerji kırıcı yapıların etkinliği Hesaplamalı Akışkanlar Dinamiği (HAD) yöntemi ile sayısal olarak incelenmiştir. Çalışmanın sayısal modellemesinde özellikle açık kanal akımı, sediment taşınımı, oyulma gibi problemlerin çözümünde başarılı bir yazılım olan Flow3D kullanılmış olup sayısal hesaplamalardan elde edilen su yüzü, basınç değerleri ve hız profilleri model ölçeğiyle (1/100) yapılan fiziksel model deney ölçümleriyle karşılaştırılmıştır.
One pier with two stones: A case study on different stones used in the foundation of a Roman bridge
Authors: DURSUN Felat , HALİFEOĞLU Fatma Meral
Published: December 2022

Perpira is a registered ancient bridge, probably constructed during the Late Roman/Early Byzantine, to span the banks of the Batman Stream. The foundations and the piers are the surviving remains of this bridge. Considering the current state, it is known that the bridge has not been repaired since it was discovered. Therefore, the remaining parts of the structure, especially the cut stone blocks, are original and contain precious information about the construction techniques and material selection of the period in which it was constructed. During the site investigations, it has been found that the stones used in the downstream and upstream sections may be different. In order to examine this unique application, samples were collected from the piers' downstream and upstream sections. The samples were then used to evaluate their petrographic, geochemical and engineering properties. At the macro scale, the questioned samples' petrophysical characteristics seem similar. However, the variances in their physicomechanical, petrographic, and mineralogical features indicate that they have distinctly different characteristics. The laboratory results demonstrate that the stone used in the upstream section is dolomite and has a strength of 25.21 MPa and a porosity of 25.38 percent, while the one used in the upstream section has a strength of 59.93 MPa and a porosity of 5.80 percent. According to the experiment results, it can be stated that Romans constructed this structure using highly competent engineering knowledge and material optimization. The findings also highlight how even a single piece of artefacts may provide new insights for understanding ancient material application practices.
Automated Detection of Alzheimer’s Disease using raw EEG time series via. DWT-CNN model
Authors: ŞEKER Mesut , ÖZERDEM Mehmet Siraç
Published: December 2022

Dementia is an age-related neurological disease and gives rise to profound cognitive decline in patients’ life. Alzheimer’s Disease (AD) is the progression of dementia and AD patients generally have memory loss and behavioral disorders. It is possible to determine the stage of dementia by developing automated systems via. signals obtained from patients. EEG is a popular brain monitoring system due to its cost effective, non-invasive implementation, and higher time resolution. In current study, we include participants of 24 HC (12 eyes open (EO), 12 eyes closed (EC)), and 24 AD (HC (12 eyes open (EO), 12 eyes closed (EC)). The aim of current study is to design a practical AD detection tool for AD/HC participants with a model called DWT-CNN. We performed Discrete Wavelet Transform (DWT) to extract EEG sub-bands. A Conv2D architecture is applied to raw samples of related EEG sub-bands. According to obtained performance metrics calculated from confusion matrices, all AD and HC time series are correctly classified for alpha band and full band range under both EO and EC. Classification rate of AD vs. HC increases under EO state in all cases even if EC is commonly preferred in other studies. We will add MCI patients with equal size and similar demographics and repeat the experimental steps to develop early alert system in future studies. Adding more participants will also increase generalization ability of method. It is also promising study to combine EEG with different modalities (2D TF image conversion, or MRI) in a multimodal approach.
Communities of Inquiry and the Case of the "Distance Education" Group during the COVID-19 Pandemic
Authors: Kavoura Theodora
Published: December 2022

According to the Community of Inquiry (CoI) Framework, successful learning experiences are supported by the presence and interaction of cognitive, social, and teaching elements. Since the CoI Framework has been widely used to examine the quality of educational interactions, its applicability to non-formal education has not been adequately explored. This research is a case study of the "Distance Education" group on Facebook. It was mainly carried out during a period of restrictions due to COVID-19, when most schools in Greece remained closed.
This study explores the process by which shared understanding and learning were fostered in a Peer-to-Peer setting of teachers. Through group exploration and interaction team members were able to provide solutions and answers while focused discussion and smooth functioning were controlled by administrators who were also educators.
The results of this research show the presence of social, cognitive, and teaching elements during the discussions. Similarly, the findings of the analysis of the discussions show that they contained content directly related to the learning activities, thus indicating the presence of the cognitive component. Off-topic discussions helped develop social relationships. Overall, when interpreted within the framework of CoI, the results reveal that all three components of an effective online learning experience were present in the context of Peer-to-Peer conversations between teachers.
The most important finding is that during the pandemic, teachers had to develop reciprocal relationships and create common plans and projects that helped them overcome difficulties and, finally, reflect dialectically on the extraordinary conditions created by the pandemic. The results of the research can be used by professionals who wish to apply the framework in a non-formal educational setting.

Authors: Gacar Sultan Yıldız
Published: December 2022

Alevi inanç sistemi ocak merkezli kurumsallaşmıştır. İnanç sistemi, Anadolu’dan Balkanlara kadar çok geniş bir coğrafyada ocaklarla varlığını sürdürmüştür ve sürdürmeye devam etmektedir. Ocaklara ve yörelere göre farklılıklar gösteren Alevi inanç sistemi, zengin bir ritüel evrenine sahiptir. Ocaklara bağlı topluluklar genel anlamda ocağın kurucu karizmatik inanç önderinin adı ile adlandırılır. Çalışmamıza konu olan Tahtacı Alevileri, yaptıkları meslek ile adlandırılmış bir zümre olarak karşımıza çıkmaktadır.Tahtacılar tarihsel süreç içerisinde Horasan’dan Anadolu’ya göç eden, eski Türk inançlarını ve kültürünü beraberinde getiren ve günümüzde Akdeniz, Ege ve Marmara bölgelerinde yaşayan Alevi topluluğudur. Tahtacı ismini konargöçer yaşam tarzında ağaç işçiliği ile uğraşmaları sebebiyle almışlardır. Zaman içinde Tahtacı adlandırması bir inanç toplumunun adı haline gelmiştir. Tahtacı Alevileri diğer Alevi zümrelerinde olduğu gibi ocak merkezli yapılanır. Tahtacı Alevilerinin bağlı olduğu iki ocak vardır. Bunlardan birincisi karizmatik inanç önderinin Durhasan Dede olduğu Yanyatır Ocağı, ikincisi ise karizmatik inanç önderi İbrahim Sani olan Hacı Emirli Ocağı’dır. Yanyatır Ocağı’nın merkezi Adana Ceyhan Durhasan köyü, Hacı Emirli Ocağı’nın merkezi ise Gaziantep Islahiye Kabaklar köyüdür.Tahtacı Alevi toplumu, kapalı toplum yapısını en güçlü şekilde yaşatan zümrelerin başında gelmektedir. Tahtacılar, ritüel evrenlerinin farklılığı ve yaşam biçimleri ile kapalı toplum yapısını son elli yıla kadar canlı bir şekilde yaşatmayı ve aktarmayı başarmıştır. Bu makalede, Tahtacı Aleviliğine ait kutsal belleğin yaşamasını ve aktarılmasını sağlayan, inanç sistemi içerisinde on iki hizmetten biri olan sazandarlık hizmeti, İsmail Gacar örneklemi ile incelenmeye çalışılacaktır. Konunun daha iyi anlaşılması açısından öncelikle Alevi inanç sisteminin ocak merkezli yapılanmasının üzerinde durulacak daha sonra Tahtacı Alevi ocakları ve bu ocaklarda gerçekleştirilen hizmetler ve cem ritüelleri bağlamında Tahtacı Alevilerinde sazandarlık hizmeti açıklanacaktır.

Hama wereng cokelat (Nilaparvata lugens Stal.) telah lama menjadi masalah utama dalam budidaya padi di Indonesia dan beberapa negara Asia lainnya. Merakit tanaman yang memiliki ketahanan terhadap hama ini, dipandang sebagai pendekatan yang lebih efektif dan ramah terhadap lingkungan dan manusia. Penelitian ini bertujuan untuk memperoleh perbedaan pada karakter penting padi antara kultivar padi tahan dengan kultivar rentan wereng cokelat, selain itu juga untuk mendapatkan marka-marka SSR yang bisa digunakan untuk Marker Assisted Selection (MAS) dan hubungannya dengan karakter penting. Riset ini meliputi pengamatan karakter penting dan skrining delapan marka SSR yang diduga berkaitan dengan gen bph (ketahanan terhadap wereng cokelat) pada lima kultivar padi tetua yaitu PTB-33 (genotipe tahan), IR-64, Pandan Wangi, Ciherang, dan Sintanur. PTB-33 memiliki laju fotosintesis yang lebih tinggi (toleran), trikoma yang lebih panjang, dan kandungan protein yang lebih rendah dibandingkan kultivar lainnya yang diuji. Hasil visualisasi marka RM8213 menunjukkan adanya polimorfisme pita DNA pada genotipe tahan PTB-33 dengan kultivar lainnya. Selain itu, marka RM586 dan RM589 juga menunjukkan adanya polimorfisme pada kultivar PTB-33 dengan kultivar lainnya kecuali dengan kultivar IR-64. Hasil analisis Z-Mantel antara marka SSR dengan karakter penting genotipe uji menunjukkan bahwa gen Qbph4 dan Bph17(t) mempunyai korelasi yang sangat tinggi dengan karakter laju fotosintesis dan panjang trikoma, sedangkan gen gen Bph3 dan bph4 berkorelasi tinggi dengan kandungan protein. Ketiga karakter tersebut diduga berperan penting dalam mekanisme pertahanan terhadap hama wereng cokelat pada padi.
