Cherry laurel is one of the most important cherry species and naturally grown in Black sea region in Turkey. Its fruits are sold at high price in local markets in northern parts of Turkey. Cherry laurel fruits are very perishable with a limited shelf life due to a high metabolic activity and susceptibility to mechanical damage and microbial attack. The effect of edible coatings (EC) based on caseinat, Semperfresh and lecithin on the fruit quality, bioactive content and antioxidant activity of cherry laurel fruits stored at 4 ± 1 °C for 15 days was evaluated.

The commercialization of mushrooms is critical because they have a short shelf life. For this reason, we investigated the effect of agar-agar and egg white protein on weight loss, polyphenol oxidase and catalase, protein content, total phenolics, total antioxidant capacity, respiration rate, ethylene production and storability of button mushrooms. Our findings suggested that the treatment of edible coating delayed remarkably senescence and maintained the quality of button mushroom.

The age-stage, two-sex life table method was used for data analysis. The results indicated that EPF treatments affected the population growth rate of the aphids by causing prolongation of the development time, decrease in survival rate, shortening of adult longevity, and decrease in reproduction. The intrinsic rate of increase (r) and the finite rate of increase (λ) reflecting combined effects of all life history parameters were the highest in the control group and the lowest in M.

Broccoli is rich in vitamins, antioxidants, minerals, free from calories and fat necessary for a healthy life. The production of broccoli is poor as compared to the developed world because of different biotic and abiotic stress. The nutritional stress is increasing with the passage of time because of low soil fertility and numerous stresses occur in the root zone of plants which reduce the uptake of minerals.

Tomato leaf miner is an aggressive and invasive pest that causes serious damage in tomato production, resulting in up to 100% yield losses during serious outbreaks. The management of tomato leaf miner with synthetic pesticides is difficult due to its leaf mining habit, short life span, high reproductive rates, and insecticide resistance problem. In this study, sequences of the mitochondrial cytochrome oxidase I (mtCOI) gene of Tuta absoluta specimens were analyzed and compared with the available COI sequence data members from GenBank.

The use of ozone for the sanitization of fresh-cut produce has been postulated during all steps of the cold chain from harvest to consumption. However, little is known about its effects on the postharvest quality of minimally processed spinach. In the present study, the effects of different doses of ozone on the storage life and quality of minimally processed spinach were determined and compared with sodium hypochlorite.

The research aimed to assess the effects of methyl jasmonate (0.25, 0.5, and 1.0 mM MeJA) on weight loss and phytochemical compounds of kiwifruit (Actinidia deliciosa cv. ‘Hayward’) throughout the cold storage and shelf life. Kiwifruits were stored at 0 ± 0.5°C and 90 ± 5% RH for 180 days, and at 20 ± 1.0°C and 80 ± 5% RH for 5 days in shelf life conditions. During cold storage, weight loss was significantly lower (P < 0.05) in 0.25 and 1.0 mM MeJA treatments than those of control and 0.5 mM MeJA treatments. The highest flesh firmness was determined in MeJA-treated fruits.

As Carlo (2001) comments in a recent review, “research on cross-language transfer has made some progress with regard to the issue of identifying particular skills that appear susceptible to transfer from first- to second-language reading. However, questions remain concerning the specification of the cognitive mechanisms responsible for transfer as well as the developmental parameters that constrain transfer effects.

Move the gate limit to 10 and 90 percent and check for lead or lag. A lead or lag problem is when the differences between gate limit and gate position are not equal. The gates are leading the gate limit if the gate position matches the gate limit at 10 percent and moves to 95 percent with the gate limit set at 90 percent. The gates are lagging the gate limit if the gate position matches the gate limit at 10 percent and moves to 85 percent when the gate limit is set at 90 percent. ...

Trypanosomiasis, usually caused in camels by the protozoan Trypanosoma evansi, is a major clinical disease and cause of economic loss. Unlike other trypanosome species, T. evansi does not have to undergo part of its life cycle in tsetse flies and it is transmitted mechanically by other biting flies. These flies are usually of the tabanid group, mainly of the genus Tabanus, but some so called stable flies of the genus Stomoxys, also transmit the disease. In some of East African countries, the major tabanid vectors are Philoliche zonata and P. magretti. ...

I loved outdoor life and hunting. Some way a grizzly bear would come in when I tried to explain forestry to my brother. "Hunting grizzlies!" he cried. "Why, Ken, father says you’ve been reading dime novels." "Just wait, Hal, till he comes out here. I’ll show him that forestry isn’t just bearhunting." My brother Hal and I were camping a few days on the Susquehanna River, and we had divided the time between fishing and tramping. Our camp was on the edge of a forest some eight miles from Harrisburg. The property belonged to our father, and he had promised to drive...

Service gauges play an important role in diagnosing faults on refrigerating equipment. Low suction pressure can be related to a number of faults. It is normally associated with restricted refrigerant flow to the evaporator, but in some cases it can be due to the improper setting of a temperature control. As well as maintaining a design temperature, it is vital that the correct humidity conditions are achieved for the type of product being stored. It is important that the temperature difference (TD) between the product being stored and the refrigerant is correct for that product.
