No full textWOS: 000491877200008This research was conducted to determine the plant height (cm), stem diameter (mm), number of branches (number plant(-1)), seed yield (kg da(-1), panicle ratio (%), stem yield (kg dal), biological yield (kg da(-1)) and harvest. index (kg da(-1))in Titicaca variety of quinoa (Chenopodium quinoa Wind.) cultivated at different row spacing (17.5, 35.0, 52.5 and 70.0 cm) and intra-row spacing (10, 20, 30 and 40 cm). The experiment was established at the research farm at Agricultural Practice and Research Center, Igdir University with 3 replications as a factorial design in 2017 year. According to the study results, the effects of different row spacing on plant height., stem diameter, number of branches, seed yield, stem yield and biological yield in quinoa were found to be significant. On the other hand. the effect of different row spacing on bunch ratio and harvest index quinoa was found to be also insignificant.. In order to produce seeds under Igdir ecological conditions, it. was determined that cultivation of quinoa with 35 cm row spacing and 1.0 cm intra-row spacing will be more suitable. In case of sowing of quinoa at determined distances. it was determined that 597.3 kg da(-1)seed and 636.1 kg da(-1) stem could be taken
Mesoporous Materials in Biofuel Cells
No full textWOS: 000458589000007In biological systems, the conversion of chemical energy into electrical energy exhibited the importance of biological fuel cells. Thus, studies on the use of microbes and enzymes in fuel cell devices have recently increased. Reduced fossil resources and damage to the environment have led to an increase in the search for new energy sources. Electric energy can be obtained by using microbial and enzymes in fuel cells. The efficiency and durability of the material to be used in cathodic and anodic electrodes enable the efficient use of the biofuel cell. It is very important to know the properties of the membrane materials that provide ion transfer between the cathode and the anode. So, the characteristics of the materials used in these fuel cells, which can be expressed as biological fuel cells, affect the energy efficiency. This chapter is aimed to report recent developments in microbial fuel cells, enzymatic fuel cells and carbon-based fuel cells and the materials used in these fuel cells
Friedrich Parrot's Mount Ararat Research Expedition
No full textWOS: 000473315000005The true expeditions that started during the 15th century were replaced by "research expeditions" in the era of 19th century imperialism. During this time, Russia was one of the countries that launched large scale expeditions with an imperialistic perspective. The Russians led an expedition to Mount Ararat (Agri Dagi) similar to their expeditions to various other regions throughout Asia. Chosen thanks to his "mountainous terrain" studies during previous research expeditions, Friedrich Parrot, a German naturalist and explorer, pioneered this Russian expedition to Mount Ararat. Having started his expedition from Dorpat (present day Tartu), in late March of 1829 Parrot arrived in Yerevan in early September and from here, he headed towards Mount Ararat. Parrot's first two climb attempts ended in failure. However, on his third attempt on September 27th, 1829, he successfully completed the climb. After reaching the summit of Mount Ararat, he went on to Dogubayazit and visited many locations around Igdir Plain. Recording his geographical observations and expedition notes in his book, Reise zum Ararat, in Germany in 1834, he provided the physical geographical features of Mount Ararat as well as lively accounts of cultural lifestyles and means of existence in the region. Parrot's Russian-supported expedition particularly attracted the attention of scientists, explorers, and missionaries. Numerous visits to Mount Ararat followed until the early 20th century and a number of publications regarding the region appeared
Annfal evalfation of nftritional valfes of Salsola rfthenica evalfated as a potential feed sofrce in arid-pastfre areas
No full textHalophyte species, which can maintain their greenness, productive power and high nutritional values under extreme conditions, may relieve the nutrition problem experienced especially during summer, autumn and winter seasons; and they may even close the gap in feed amounts. In this respect, Salsola ruthenica, which grows in arid-pastures in the northeast of Turkey, is observed to be an important feed source in the nutrition of especially small ruminants. The objective of this study was to contribute the determination of appropriate grazing time for achieving higher animal performance and to reveal whether it meets the daily nutritional requirements of small ruminants by determining the potential nutritional value of S. ruthenica throughout a year. Research was carried out by design a randomized trial plots with three replications on a protected 5 da pasture. Samples were collected at the 15th of each month throughout the year (between May 2015 and April 2016) and analysed for the contents of crude protein (CP), neutral detergent fibre, acid detergent fibre, acid detergent lignin, dry matter digestibility, digestible energy, metabolize energy and relative feed value (RFV). The results showed that the nutritional composition significantly varied throughout the year, and that maturation process has a decreasing effect on nutrient contents. S. ruthenica has a CP of 9.75% and a RFV of 82.01 during autumn, which were similar to the values obtained from the cultured feed plants, whereas S.ruthenica have a 23.93% of CP and a 273.88 of RFV at the end of spring and a 15.85% of CP and a 167.58 of RFV during the summer, showing a significantly higher nutritional value than that of the cultured feed plants. These results suggested that S. ruthenica can sufficiently meet the daily nutrient requirements of grazing small ruminats through out the grazing periods starting from the spring to the autumn in arid regions, and that S.ruthenica is a good alternative source of fodder during winters when properly mixed with protein-rich feed supplements. © by PS
Urban households' willingness to pay for milk safety in Samsun and Trabzon provinces of Turkey
No full textWOS: 000500345300010Purpose - The purpose of this paper is to examine urban households' willingness to pay (WTP) for milk safety and to analyze the factors affecting WTP premiums using data obtained from surveys conducted in Samsun and Trabzon provinces, Turkey. Design/methodology/approach - Contingent valuation and censoring methods including the error-dependent bivariate Heckman SS model were used for estimating WTP for milk safety and its effective factors, respectively. Findings - The study indicates that 68 percent of the households were willing to pay 0.35 per liter for improving the safety of milk. The model results show that satisfaction with food safety standards, being married and full-time employment have statistically significant positive effects on the WTP for ISO-certified milk. However, purchasing milk from farmers or open-air markets, age, having a child six-year old or younger, and high school or higher education have statistically significant negative effects on the WTP for ISO-certified milk. Research limitations/implications - The main limitation of the current study is that only urban consumers' WTP and effective factors for milk safety were examined in two provinces of Turkey. Practical implications - More rigorous implementations of food safety standards, traceability systems and effective educational campaigns could promote households' food safety awareness and increase their demand for milk safety. Social implications - Knowing what factors are involved in consumer WTP is extremely important for decision makers to create new social policies in the region or country. Originality/value - A similar study has not been conducted in Turkey. The novelty of this study is the specification and robust estimation of three different but competing models to reveal the wide range of WTP amounts for safe milk.Scientific and Technological Council of TurkeyTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [2219]; Ondokuz Mayis University (the program of 1922)Ondokuz Mayis UniversityThis study was supported by both the Scientific and Technological Council of Turkey (the program of 2219) and Ondokuz Mayis University (the program of 1922).

Genetic evaluation of linear type traits and their association with milk production traits in beetal goats in Pakistan
No full textData on linear type and milk production traits of Beetal does (n=127) were analyzed to estimate variance components hence genetic parameters and to find the relationship between linear type and milk production traits fitting an individual animal model. Fixed effects were flock and parity in the model while linear and quadratic effects ofage of doe were fitted as covariables. Genetic parameters (heritability estimates) of linear type traits and their correlations with milk production traits were computed using ASREML software. Heritability of various body measurement traits varied from 0.04 to 0.98. Genetic correlations between different body measurements and milk production traits ranged from-0.41 to 0.88 for lactation milk yield (LMY) and from-0.69 to 0.64 for lactation length (LL). Phenotypic correlations in corresponding combinations ranged from-0.33 to 0.90 for LMY, and from-0.46 to 0.89 for LL. In conclusion, some of thecorrelationscould provide strong effects in selection and prediction of milk production from linear type traits. © 2019, Pakistan Agricultural Scientists Forum.

Tannic acid as a natural antioxidant compound: Discovery of a potent metabolic enzyme inhibitor for a new therapeutic approach in diabetes and Alzheimer's disease
No full textPubMed: 30974029Multiple studies have been recorded on the synthesis and design of multi-aim anti-Alzheimer molecules. Using dual butyrylcholinesterase/acetylcholinesterase inhibitor molecules has attracted more interest in the therapy for Alzheimer's disease. In this study, a tannic acid compound showed excellent inhibitory effects against acetylcholine esterase (AChE), ?-glycosidase, ?-amylase, and butyrylcholinesterase (BChE). IC50 values of tannic acid obtained 11.9 nM against ?-glycosidase and 3.3 nM against ?-amylase, respectively. In contrast, Ki values were found of 50.96 ± 2.18 µM against AChE and 53.17 ± 4.47 µM against BChE. ?-Glycosidase inhibitor compounds can be utilized as a novel group of antidiabetic drugs. By competitively decreasing glycosidase activity, these inhibitor molecules help to hamper the fast breakdown of sugar molecules and thereby control the blood sugar level. © 2019 Wiley Periodicals, Inc
Prediction of Selected Reproductive Traits of Indigenous Harnai Sheep under the Farm Management System via various Data Mining Algorithms
No full textIn this study, an attempt was made at predicting the values of selected reproductive parameters in Harnai sheep using different data mining algorithms (artificial neural networks - ANN, classification and regression trees - CART, chi-square automatic interaction detector - CHAID and multivariate adaptive regression splines - MARS) and indicating the most influential predictors of these traits. A total of 382 reproduction records including three predictors (month of lambing - MOL, age at first lambing - AFL and lambing weight - LW) and seven dependent (output) variables (services per conception - SPC, service period - SP, lambing interval - LI, twinning rate - TR, gestation length - GL, breeding efficiency - BE and fertility rate - FR) were used. A 10-fold cross-validation was applied to train and evaluate the models. The highest correlation coefficients (r) were found for LI (0.18 - 0.29; P?0.001), GL (0.05 - 0.21; P?0.001 to P>0.05) and FR (0.11 - 0.26; P?0.001 to P?0.05). For the remaining output variables, it was usually lower than 0.10. The smallest values of SD ratio (0.96 - 1.06) were found for LI, GL and FR. For the rest of the output variables, it was usually above 1.00. The measures of predictor importance to ANN, CART, CHAID and MARS were generally low. In conclusion, the applied method of reproductive parameters prediction was rather ineffective, indicating that more powerful input variables are required to obtain better prediction results.
