A Study on the Relationship Between Social Privacy Transformation and WhatsApp Status-Sharing Feature = Toplumsal Mahremiyet Dönüşümü ve WhatsApp Durum Paylaşma Özelliği İlişkisi Üzerine Bir İnceleme

Adil AKTAŞ

As social media has become an intensive part of human lives, the concept of privacy has become an actual question again. Due to security measures, it has become the norm to be monitored by surveillance cameras at many moments of life or to collect private information in data stores. Such normalization has facilitated the adaptation of the network society to the transparent, visible, public lifestyle offered by social media, and despite the violation of privacy, posting a status is implemented. The influence of every new technological device on human life is a reality that has been observed thr ...Более

This study aims to evaluate and reuse defective products and cotton wastes resulting from factories producing socks in Bishkek, Kyrgyzstan, in order to solve the issues related to their disposal. For this purpose, microcrystalline cellulose (MCC) was obtained after isolating the cellulose from these wastes by treating them with sulfuric acid solutions. Then, under constant NaOH and monochloroacetic acid (MCA), CMC with the highest DS value of (0.65) was synthesized at 65 degrees C for 2 hours. When the reaction time was increased (3, 4 and 5 hours) at the same temperature, the DS value decreas ...Более

Zarlık MAYMEKOV | Canarbek İZAKOV | Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Mehmet KOBYA

Under practical conditions, one of the possible solutions to the problem of treatment of hydrogen-sulfide-containing industrial wastewater is the electrochemical oxidation of sulfides. In this work, the model system Fe-NaCl-Na2S-H2SO4-H2O is considered, an experimental setup is constructed, and the electrocoagulation process is studied in a wide (288-308 K) range of temperatures of an aqueous solution of hydrogen sulfide. The optimal ratios between the initial components in the system are determined. The experimental and calculated pH of the solution are found. The system is thermodynamically ...Более

A new binary genetic programming approach to designing public transportation systems according to transit-oriented development criteria

Hasan YILMAZ

This study introduces a new evolutionary approach called Binary Genetic Programming (BGP) to design and assess public transportation systems from a sustainable development perspective. The BGP combines evolutionary system identi cation techniques with k-fold cross-validation to obtain an accurate model between the land use and transportation parameters from a sustainable urban development point of view. To assess the new model, two public transportation systems including the new tram line of Antalya (Turkey) and the bus rapid transit line of Bhopal (India) were considered. The model was employ ...Более

The effect of leaf blight disease of rice caused by Pantoea ananatis on Nikita, Osr30 and RIRE1 retrotransposons’ movements

Yılmaz KAYA

Changing environmental conditions can cause diseases in plants, leading to novel interactions between plants and stress factors. In this respect, the relationships between pathogens and plants regarding epigenetics have still been investigated. Our aim is to examine the effect of leaf blight bacterial causal agent, Pantoea ananatis isolate PaTo34a1, on barley- and rice-specific retrotransposons’ (Nikita, Osr30 and RIRE1, respectively) movements in different rice cultivars (Oryza sativa L. cv. Tosya, Cameo, Arize, Ronaldo, Osmancik-97, Kale, Baldo, Bafra, Hakkari and Vasco) collected from diffe ...Более

Optimization by Using the Taguchi Method of Boric Acid Production by Dissolving Flash Calcined Colemanite in Water Saturated with SO2

Ali Osman SOLAK

Turkey has the largest boron reserves in the world with a rate of approximately 72. The most common commercial boron reserves in Turkey are colemanite, tincal, and ulexite. Boric acid, which is the most commonly used boron compound in Turkey, is obtained from the dissolution of colemanite with sulfuric acid. In the present study, an aqueous medium saturated with sulfur dioxide instead of sulfuric acid was used in order to obtain boric acid. Colemanite ore was flash calcined at various temperatures and optimum dissolution conditions of the ore obtained in water saturated with SO2 were examined ...Более

A Multi-Objective Mathematical Programming Model for Transit Network Design and Frequency Setting Problem

İbrahim AKGÜN

In this study, we propose a novel multi-objective nonlinear mixed-integer mathematical programming model for the transit network design and frequency setting problem that aims at designing the routes and determining the frequencies of the routes to satisfy passenger demand in a transit network. The proposed model incorporates the features of real-life transit network systems and reflects the views of both passengers and the transit agency by considering the in-vehicle travel time, transfers, waiting times at the boarding and transfer stops, overcrowding and under-utilization of vehicles, and v ...Более
