Fluorescence spectroscopy for accurate and rapid prediction of meat composition

Cıldızay ÖZBEKOVA | Asılbek KULMIRZAYEV

The potential of fluorescence spectroscopy was assessed to study cow, goat, sheep and yak meat. Meat samples were taken from muscles, viz. Gluteus medius (GM), Longissimus dorsi (LD) and Semitendinosus (ST). The moisture, fat and protein content of meat samples were measured. The emission fluorescence spectra of tryptophan (305-500 nm), riboflavin (410-700 nm) and vitamin A (340-540) were recorded directly on meat samples at 290, 382 and 322 nm, respectively. Principal component analysis (PCA), partial least squares regression (PLSR) and partial least squares discriminant analysis (PLSDA) were ...More

Internal Curing and Temperature Effect on Lightweight and Heat Insulated Mortar with Recycled Concrete Aggregate

Kasım BAYNAL

One of the best methods of waste recycling in the construction sector is to employ it in concrete or mortar preparation. In this study, recycled concrete aggregate and bottom ash were used as aggregates in the mortar. Additionaly, expanded perlite which is a material providing lightness, heat insulation and fire resistance, was also used as aggregate. Calcium aluminate cement was preferred as binder to improve fire resistance. Results were obtained and evaluated in terms of flexural and compressive strength, dry unit weight, water absorption, capillarity, thermal conductivity, thermal resistan ...More

Optimisation of elastomeric bearings' vulcanisation process using response surface methodology and desirability function approach

Kasım BAYNAL

In this study, response surface methodology and desirability function approach (DFA) were used to optimise the vulcanisation process of elastomeric bearings to obtain better quality products. For this purpose, compressive stiffness and vertical deflection under maximum load were determined as response variables with a target at 198 kN/mm and 3.46 mm, respectively, in accordance with customer's request. Time, temperature and pressure were considered as control variables of the process. Experimental combinations were determined using Box-Behnken design and two repetitions were made in each combi ...More

Composition, nitrogen fraction, and amino acid profile of mare's milk produced in the mountains and highlands

Ayçürök MACİTOVA | Asılbek KULMIRZAYEV

The study was carried out to determine the effect of 2 ecological regions and lactation period on chemical (P < 0.01) and amino acid (P < 0.01) composition and nitrogen fraction (P < 0.01) of mares grazing on pastures at 1700 m (vegetation is dominated by shrubs and sub-shrubs) and 2200 m (vegetation is dominated by grasses, forbs, sub-shrubs) above sea level. The animals were kept under extensive pasture conditions and received no additional feed supplements. Milk samples were collected monthly from May to July and from May to August from mares grazing at 1700 m (Mountains) and 2200 m (Highla ...More
