Pickles, which are known to have many nutritional and health benefits, have been used as a nutritional supplement in many cultures in recent years. Lactic acid bacteria, in its natural microbiota of pickle, which have various probiotic properties such as increased natural resistance to infectious diseases in the gastrointestinal system, prevention of various infections, and reduction in cholesterol level are effective in this. In our study, various combinations of salt, vinegar and lemon acid were made to produce cabbage pickled and it was determined how it affected the natural microbiota during fermentation. When the results were evaluated in terms of the viability of lactic acid bacteria, the best results were obtained with 5.35 logarithms in the G2 produced using only 5% lemon juice from eight different groups, one of which was a control. In the G3 which was produced using 5% vinegar, this number was determined as 1.82 logarithms. At the end of fermentation, it was determined that the coliform groups in the experimental groups lost their viability. Yeasts were completed this process with an average of 1 logarithm. When all test groups were examined in terms of all microbiological results was showed that the production of 5% lemon juice G2 has optimally results in terms of growing LAB and inhibition the undesirable microbial groups

At present environmental pollution is a talked about issue. Due to environmental pollution, humans and animals face threats. The scientist has pointed out that waste is one reason for climate change. Solid, liquid, gaseous etc. are different types of waste. The experiments were conducted to determine the chemical constituents present in dairy farm wastewater, wastewater management practice and environmental impact and compare it with the groundwater Dinajpur Sadar upazila. The data concerning the dairy farm wastewater in Dinajpur was obtained through a designed questionnaire, and separate area inspection interacting with the proprietor and workers in the dairy farm. Randomly collected samples from different dairy farms. The chemical constituents of the wastewater sample were determined by a laboratory experiment. The wastewater contained Mg, Na, Ca, Cl-, K, EC, P, HCO3-, pH, TDS, DO, COD, Zn, S, BOD, HT and NO3-. The Na, K, Ca and pH concentration of wastewater under the range in groundwater in Dinajpur. However, concentrations of P, TDS, Mg, EC, Cl-, HCO3- and HT are above the groundwater range in Dinajpur. The produced wastewater was disposed of either through drainage or piping systems on fellow land, ponds, open lakes, roadside land, urban drains, and rivers. The unplanned wastewater disposal creates bad odor, and environmental pollution, seduces the growth of mosquitoes decreases the water quality, soil quality and health hazards. Therefore, it can be concluded that the prevailing dairy farm wastewater disposal system not being satisfactory. The proper disposal system should be improved to reduce environmental impacts.

Bu çalışmanın amacı, kırmızı ve beyaz LED ışığın yumurtacı tavukların eşeysel olgunluğu, performansı, yumurta kalitesi ve bazı davranış özellikleri üzerindeki etkisini belirlemektir. On altı haftalık toplam 432 kahverengi yumurtacı yarka (Lohmann) rastgele her biri 12 tekerrürlü 2 uygulama grubuna ayrılmıştır. Uygulama grupları 1) Monokromatik kırmızı LED aydınlatma ve 2) Beyaz LED aydınlatma gruplarından oluşturulmuştur. Kanatlılar, deneme süresince (16-32 hafta) zenginleştirilmiş kafeslerde barındırılmıştır. Tavukların monokromatik kırmızı ışıkta beyaz ışığa göre eşeysel olgunluğa 5 gün ve pik yumurta verimine 4 gün daha erken ulaştıkları ve deneme boyunca % 2,05 daha fazla yumurta ürettikleri belirlenmiştir. Aynı dönemde ışık renginin yem tüketimine ve yemden yararlanma oranına (YYO) etkisi önemli bulunmamıştır. Ancak, yumurta veriminin yüksek olduğu 21, 23-26 ve 29. haftalarda tavukların kırmızı ışıkta daha iyi YYO değerlerine sahip oldukları görülmüştür. Yumurta ağırlığı ve yumurta kitlesi kırmızı ışıkta daha yüksek bulunmuştur. Işık rengi, tavukların yumurta kalite özellikleri, tünek ve folluk kullanımı ve kırık yumurta oranı üzerinde önemli bir etkide bulunmamıştır. Sonuç olarak, büyüme döneminin sonunda başlayan monokromatik kırmızı LED ışık uygulaması kanatlıların daha erken eşeysel olgunluğa ulaşmalarını ve yumurtlama döneminde daha fazla yumurta üretmelerini sağlamıştır.

A Palm Nut cracking machine with an improved beater configuration was developed to effectively crack Palm Nuts of various species and sizes. This research aim at improving the quality of the Palm kernel recovered at relatively low cost during Palm kernel oil production. Durable materials were acquired locally to fabricate the machine for ease of usage and maintenance, also to make it affordable for small and large scale processors. Basic features of the machine are; hopper, electric motor (prime mower), cracking chamber, cracking beater and discharge outlet. The design of the cracking drum and beater configuration was based on the impact force required to crack the Palm Nut which is a function of Palm Nut shear strength. A 5 hp electric motor was selected based on the power required to effectively operate the machine. The machine was tested with “Tenera” varieties, three nut sizes (14.5, 22.15 and 29.43mm) and five speeds (970, 1200, 1450, 1750 and 2430rpm). Result shows that the change in machine speed significantly (P<0.05) affects all the machine performance irrespective of the Palm Nut size and variety, which agrees with the report of several other researchers. The obtained optimum machine performance values are 14,874 nuts/h, 89.5%, 98% for the machine capacity, quality performance efficiency and cracking efficiency for Tenera variety. The best crop and machine parameter for the optimum performance of the Palm Nutcracker are 29.43 mm and 970 rpm, nut size and machine speed.  It was concluded that the overall performance of this developed Palm Nut cracking beater was effective because it fell within the range of 80 to 98% efficiency.

In this study, the effect of pretreatments applied to the sewage sludge of the Tokat Municipality wastewater treatment plant (WTP), the sewage sludge of the packaged wastewater treatment plant (PWTP) of a fruit juice production plant, and the aqueous phases of their mixtures on biogas production was investigated. Chemical, thermal (microwave (MW) and hot plate (HP)) and chemical-thermal pretreatments were applied to these sludge samples. Considering the results in all samples, the highest biogas production amount and efficiency were found in the pre-biogas-unit aqueous phase of the sewage sludge of the Tokat WTP, which was applied 20% H2SO4+10-minute (min) thermal MW pretreatment, with 667.51 ml and 396.34 ml biogas/g water dissolved SM value, respectively. Statistical analyses included the Duncan comparison test for cumulative biogas production efficiencies at the end of 65 days and the maximum exponential increase function and Gompertz equations for cumulative biogas amounts. Accordingly, the most appropriate model was tried to be determined. The electricity generated at the end of the 22-day incubation period at the facility meets 36% of the electricity needed by the Tokat WTP. At the end of the experimental studies (20% H2SO4+10 min thermal MW pretreatment), it can be said according to the 22-day biogas data that the biogas production efficiency increased by 3.41 times, this would meet all the electricity needed by the facility, and that there would be an extra 23% electricity generation of the total generation. Mixing and using fruit juice PWTP and WTP treatment sludge in the production of biogas will enable both the utilization of this waste in biogas production and the weakening and reduction of high parameter values, which sometimes cause problems in the sludge discharged from the Tokat WTP due to urban wastewater treatment, to acceptable limits.

In this study, the physicochemical properties of canola and waste cooking oil biodiesels, as well as various binary biodiesel blends, were investigated according to TS EN 14214 and ASTM D 6751 standards. Critical parameters such as density, kinematic viscosity, cold filter plugging point (CFPP), calorific value, flash point, copper strip corrosion, water content, and ester yield were evaluated. The findings highlighted the notable density of C100 and W100 biodiesels, with the addition of butanol reducing density. While viscosity values adhered to standards, the addition of butanol was observed to decrease viscosity. CFPP values indicated compliance with standards only for C100 and C75W25. Flash points of C100 and W100 biodiesels met standards, but the addition of butanol to binary biodiesel blends lowered flash points. Copper strip corrosion values were determined to comply with standards for all fuels. Calorific values demonstrated the prominence of C100 and W100 biodiesels, with the addition of butanol observed to decrease calorific values in binary biodiesels. While water content favored canola biodiesel over waste cooking oil biodiesel, the addition of butanol to binary biodiesels increased water content. Regarding ester yield, C100 biodiesel exhibited the highest yield, and the addition of butanol to binary biodiesels increased ester yield. In conclusion, this study thoroughly analyzed the physicochemical properties of biodiesel and blend fuels, revealing the impact of butanol addition on these properties.

In this study, a new bitter chocolate with functional properties was produced by using different tempering temperatures with different ratios of wolfberry addition and physicochemical, antioxidant, textural and sensory properties of these chocolates were determined. It was observed that fruit ratios on bitter chocolate had a statistically significant (P<0.01) effect on DPPH, ABTS and hardness values, while there was no significant effect on total flavonoid amounts. It was determined that tempering temperature had a significant effect (P<0.01) on pH, reducing sugar, sucrose, total phenolic content (TPC), DPPH, ABTS, total flavonoids (TFC) and hardness values, while it had no significant effect on total dry matter and total sugar values. The rich total phenolic and antioxidant content of the added wolfberry fruit and its substitution for sugar improved the functional properties of the chocolate. As a result of the study, it was possible to introduce a value-added functional product with wolfberry additive to the market, thus pioneering the production of new products as well as the fresh use of the fruit.

The increase in the diversity of needs arising from population growth, technological development and globalization causes more use of limited natural resources and brings with it consequences such as wear and pollution of resources. This study focused on the dam lakes on the Kızılırmak River in Türkiye, whose fisheries production rights were leased. There are İmranlı, Yamula, Bayramhacılı, Hirfanlı, Obruk, Boyabat and Derbent dam lakes on which the right to produce fishery products are leased on Kızılırmak, which is the longest river within the borders of Türkiye. Among these, the most rented region is in the Hirfanlı Dam Lake. Sustainability of fisheries in these dam lakes on Kızılırmak River is important in terms of meeting healthy protein demand and socio-economic development. Fishing, which has commercial value in these dam lakes, provides both employment and significant economic contribution to the people of the province and district where they are located. In order to benefit from this potential in a healthy way, it has been concluded that it is very important to operate these dam lakes in a balance of protection and use. However, it is necessary to increase the incentives and support of fishermen especially in these fishing regions.
