How does arsenic speciation (arsenite and arsenate) in groundwater affect the performance of an aerated electrocoagulation reactor and human health risk?

Mehmet KOBYA

Arsenic (As) occurrence in water resources has become one of the most critical environmental problems worldwide. The detrimental health impacts on humans have been reported due to the consumption of As-contaminated groundwater resources. Consumption of As-containing water over the long term can cause arsenicosis and chronic effects on human health due to its toxicity. Several treatment processes are available for As removals such as coagulation, ion exchange, adsorption, and membrane technologies but they have various major drawbacks. In the present work, therefore, an aerated electrocoagulati ...More

A Singularly Perturbed System of Parabolic Equations

Asan ÖMÜRALİEV | Peyil Esengul Kızı

The work is devoted to the construction of the asymptotic behavior of the solution of a singularly perturbed system of equations of parabolic type, in the case when the limit equation has a regular singularity as the small parameter tends to zero. The asymptotics of the solution of such problems contains boundary layer functions.

Synthesis and characterization of novel organo-hydrogel based agar, glycerol and peppermint oil as a natural drug carrier/release material

Nahit AKTAŞ

The very recent Covid-19 pandemic has made the need to understand biocompatible polymers as support material in drug delivery systems and controlled release clearer, especially for organo-hydrogels. This study aims to synthesize various new polymeric materials called gels, hydrogels, and organo-hydrogels according to the monomer used and to investigate their use as drug release systems. The agar-glycerol (AG) pair was used to synthesize the polymers, N, N, methylene bisacrylamide (MBA, m) and glutaraldehyde (GA, g) were used as cross-linkers and peppermint oil (PmO) was included to obtain the ...More

Arsenic removal from groundwater using an aerated electrocoagulation reactor with 3D Al electrodes in the presence of anions

Mehmet KOBYA

Co-occurrence of arsenic and anions in groundwater causes a severe health problems and combine effects of these pollutants significantly affect performance of treatment process. Thus, this study has been conducted to examine the combine effects of anions on arsenic removal using aerated electrocoagulation (EC) reactor with 3D Al electrodes in groundwater. A 3-level, six factors Box-Behnken experimental design (BBD) was applied to investigate the individual and combine effect of anions and operating time: phosphate (x(1): 1-10 mg L-1), silica (x(2): 20-80 mg L-1), bicarbonate (x(3): 130-670 mg ...More

Synthesis and Characterization of Hydroxypropyl Acorn Starch (HPAS) From Oak Acorn

Mustafa DOLAZ

The utilization of forest auxiliary products and their conversion into products with higher added value is important for the use of renewable resources. For this purpose, acorns belonging to the Q. coccifera species were collected in November, which is their ripening period, and dried and ground in the laboratory. Then, acorn starch (AS) was isolated from the sieved acorn flour. For 5 g of this isolated AS, hydroxypropyl acorn starch (HPAS) with the highest molar substitution (MS = 0.319) was synthesized by optimizing at 45 degrees C for 5 h with 30 g of propylene oxide and 1.88 g of NaOH. The ...More

Evaluation of the biological activities of olivetoric acid, a lichen-derived molecule, in human hepatocellular carcinoma cells

Ali ASLAN

Many lichen secondary metabolites contributed to the field of pharmacology as an active ingredient of different drugs for years. In the present study, we aimed to test the anticancer activity of olivetoric acid (OA), which we isolated from Pseudevernia furfuracea (L.) Zopf in human hepatocellular carcinoma cells (HepG2). In addition, we used non-tumoral human liver cells (THLE2) to test the level of side effects of OA in vitro. For this purpose, cytotoxic (apoptotic and necrotic), oxidant, genotoxic activities and expression levels of apoptotic genes caused by different concentrations (12.5-40 ...More

Parabolic Problem with a Power-Law Boundary Layer

Asan ÖMÜRALİEV | Ella ABILAYEVA | Peyil Esengul Kızı

We construct a regularized asymptotics of the solution of the first boundary value problem for a singularly perturbed two-dimensional differential equation of the parabolic type for the case in which the limit equation has a regular singularity. There arise power-law and corner boundary layers along with parabolic ones in such problems.

Economic Impacts of Bt (Bacillus thuringiensis) Cotton

İbrahim İlker ÖZYİĞİT

In recent years, high-yield production has gained importance due to the decrease in agricultural fields in the world and the rapid increase in the population. Cotton is an important source of income for farmers worldwide and is an important crop, especially for the textile industry. Bt-cotton technology, which entered our lives in 1996, has been quickly adopted in many developed and developing countries. It has been shown to provide advantages in many areas. In particular, the economic growth is gaining importance every year. Additionally, it has also brought an environmentally friendly soluti ...More

Intravenous and Oral Fluid Therapy in Neonatal Calves With Diarrhea or Sepsis and in Adult Cattle

İsmail ŞEN

Optimal fluid therapy protocols in neonatal calves and adult cattle are based on consideration of signalment, history, and physical examination findings, and individually tailored whenever laboratory analysis is available. Measurement of the magnitude of eye recession, duration of skin tenting in the lateral neck region, and urine specific gravity by refractometry provide the best estimates of hydration status in calves and cattle. Intravenous and oral electrolyte solutions (OES) are frequently administered to critically ill calves and adult cattle. Application of physicochemical principles in ...More

The Usability of Cytological and Immunocytological Methods for Rapid Diagnosis of Encephalitic Listeriosis in Ruminants

Fatih HATİPOĞLU

Although the clinical and pathological findings are important in the diagnosis of listeriosis, to isolation or to be shown the presence of the bacterium must be required for the definitive diagnosis. This study aims to investigate the availability of imprint cytological (IC) and immunocytochemical (ICC) methods in comparison with histopathological and immunohistochemical (IHC) methods for the rapid diagnosis of encephalitic listeriosis. In the study, the touching and smear preparations taken from the pons and medulla oblongata of 25 ruminants suspected with listeriosis by neurological symptoms ...More

Cytogenetic and Oxidative Status of Cultured Lymphocytes after Exposure to Extracts from Rhizopogon Mushrooms (Agaricomycetes) In Vitro

Ali ASLAN

In this study, acetone and water extracts obtained from edible mushrooms, Rhizopogon luteolus Fr. and Rh. roseolus (Corda) Th. Fr., containing important bioactive components were used. Total antioxidant capacity (TAC) and total oxidative stress (TOS) levels were examined on human peripheral lymphocyte culture treated with the respective extracts. Levels of genetic damage and cytotoxic effects of the respective extracts on lymphocytes were also tested. In general, when TAC levels of the extracts on cells were examined, a concentration-dependent increase was observed; a negative correlation was ...More
