Dielectric properties of materials are used for evaluating their interactions with electromagnetic energy. Dielectric properties of food materials are required for various applications in food industry such as microwave (at 915 or 2450 MHz), radio wave (at 13.56, 27.12 or 40.68 MHz) and magnetic field processing. In order to understand the response of food materials to electromagnetic energy, dielectric parameters must be determined as a function of frequency, temperature, composition and moisture content. In this review, the dielectric properties of different food groups were listed depending on temperature and frequency ranges. In addition to the literature data of dielectric properties, the penetration depths of microwave or radio wave through food groups were calculated. The effects of temperature and composition (mostly moisture content) on dielectric properties depend on the type of the food and sometimes on frequency. However, the effect of frequency is constant; increased frequency decreased dielectric constant, loss factor and penetration depth. The lowest calculated penetration depth belonged to the fish surimi gel as 3.39 mm at microwave frequency whereas they were high generally for fats, oily seeds and flours (max was 372602 mm for corn flour). It appears that dielectric properties of foods should be investigated further depending on the interactions between frequency, temperature and composition. And then, dielectric heating based on the aim of the process can be applied accordingly. Besides, it appears that the moisture content and especially the dipole rotation and the conductivity movements of the molecules in free water content of the food are some of the most critical factors influencing the dielectric properties of food materials.

This study was conducted to determine profile and productivity characteristics of soils formed over the alluvial terraces located at different elevations and distances from Meriç River. Soil profiles were sampled at four different points located vertically at different distances from Meriç River and soil horizons were defined in these profiles. Twenty-eight disturbed soil samples were taken, and physico-chemical analyses were performed on these profile samples. While paddy farming is practices over the fields where profile 1 (P1), profile 3 (P3) and profile 4 (P4) are located, the field where profile 2 (P2) is located has long been used as pasture. Organic matter content of soils was generally “low” and “very low”. The highest organic matter contents were observed in A1 horizon of P2 (3.22%) and Ap horizon of P4 (2.09%). Soil pH values were generally “slightly acidic” and “neutral”. Soils were “calcareous” in P2 and “slightly calcareous” in the other profiles. Salinity was encountered in P2. Electrical conductivity (EC) of A1 horizon of this profile was measured as 6.51 dS m-1. Sodium (Na) content of this horizon was also “very high”. As compared to other profiles, P2 was located at a lower elevation, thus wet through majority of the year. Therefore, P2 was generally wet and had redoximorphic characteristics, high clay content and thus poor drainage conditions. P1 was located at the closest position to the river, thus had higher sand contents than the other profiles. Based on clay content, cation exchange capacity (CEC) was the greatest in P2 and the lowest in P1. Available nutrient contents of the profiles decreased through the depth of the profile. Phosphorus (P), iron (Fe), cupper (Cu), manganese (Mn) and zinc (Zn) contents of upper layers were “sufficient” and “excessive”. On the other hand, potassium (K) content was “sufficient” only in P2 and “low” in the other profiles.

Salinity stress is one of the most important and common abiotic stress factors that cause significant physiological and metabolic changes in plants, negatively affecting plant growth and development, and causing decrease in product quality and quantity. The elucidation of the molecular control mechanisms associated with salt stress tolerance is based on the activation and /or inactivation of various stress-related genes. Salt Overly Sensitive (SOS) tolerance mechanism under salt stress is of great importance in terms of salt tolerance of the plants. Although this mechanism has been studied for many years, the physiological changes that the plants give as a result of mutation of the genes in the pathway under different levels of sodium chloride (NaCl) during development have not been examined comparatively. In this study, we found that the Arabidopsis thaliana sos1-1 mutant plant showed sensitivity to 10 mM NaCl while the sos3-1 and hkt1-1 mutants showed tolerance. The sos1-1, sos3-1 and hkt1-1 mutants showed increasing sensitivity when NaCl was applied beyon 50 mM of concentration. In addition, plants did not show significant sensitivity for 1 day of stress application, while significant effects were observed in plant root length when exposed to salinity for 3 to 4 days. Col-0, hkt1-1 and sos3-1 roots treated with low levels of NaCl for a short term were positively affected in length. In the light of these results, the amount and duration of salt stress is very critical in Arabidopsis thaliana's responses to the stress and determination of molecular tolerance pathways.

Wheat is an essential crop throughout the world and especially in Pakistan. It has a great yield potential which can cope with the raising food challenges of the world but there is a more need to increase its yield with its increasing demand. There is a need to increase the yield by improving the genetic characters. Breeder’s intention is to find out the variability in the genetic lines and by the use of these lines they can develop the high yielding breeding lines. Multi-ovary is a novel character to increase the number of grains per spikelet. What type of gene actions control that? From this review we get that some support the single dominant gene controlled trait, some support the two recessive non-complementary genes controlled trait and some favour the both as it is controlled by both dominant and recessive genes in different tri-grain lines. Secondly there is a need to study the genetic variation for the yield contributing traits. So that we can improve our genotypes to attain high yield. How we can evaluate yield and yield components. Combining ability is a considerable tool for this. Literature revealed that additive gene action contributes more towards yield than non-additive. In this many lines also came forward as good combiners which in future we can use them for a successful wheat hybridization program.

In this study, it is aimed to obtain a new and functional product as a result of adding the remaining black carrot into powder form in different proportions (10, 20 and 30%). Biscuits without waste fermented carrot powder (WFCP) were taken as control group. When ascorbic acid, total phenolic content and antioxidant activity values of WFCP were examined, it was found 1032.75 mgAA / 1000g, 4254.92 mg GAE / kg dry weight and % inhibition 43.30, respectively. The textural properties of the biscuit dough with the addition of AFHT were investigated. Moreover, the effect of adding WFCP on colour values, water activity, moisture, ash, ascorbic acid, total phenolic content, antioxidant activity and textural properties of biscuits were determined. With the addition of WFCP, L* and b* values were decreased and a* values were increased in biscuits compared to control sample. Water activity and ash values increased as WFCP rate increased in biscuits. Ascorbic acid, total phenolic and antioxidant activity (DPPH) values of biscuits added with WFCP (30%) increased by 4.89, 7.22 and 4.04 times, respectively, compared to the control group. The addition of WFCP also improved the textural properties of the biscuits, while the hardness value of control group was found to be 4175.87 g force, the highest hardness value was obtained as 6494.09 g force for 20% WFCP added biscuits. In sensory evaluation, the biscuits with the addition of 10% WFCP gained the highest likelihood with 5.6 in terms of general acceptability.

The improvement and use of sustainable energy technologies are developing by the reason of increasing energy demand. Due to the fossil fuels negative effects on the environment, energy efficient building and their industrial applications have become an important research topic.

Especially hybrid systems that are combined with phase change materials and biomass are investigated.

North Sinai governorate is one of the largest desert areas in terms of intensity of agricultural extension work, In spite of efforts by state agencies to bring about agricultural development in the governorate, agriculture is still somewhat characterized by primitive traditional methods, making agricultural development rates almost indistinguishable, And with the scarcity of extension research carried out in North Sinai in the field of environmental SWOT analysis, It was necessary to conduct the study that is trying to analyze the current situation of agricultural extension in North Sinai governorate through identifying the strengths; weaknesses, opportunities, and threats (SWOT). A participatory SWOT analysis study using open-ended qualitative-type instrument was conducted; Research data were collected through personal interviewing questionnaire with 90 respondents representing 75% of the total extension workers in North Sinai Governorate, during the period from May till October 2018. The results showed that the most important strengths of these were that a large proportion of the extension workers are specialized in agricultural extension, more than half of the guides were from rural areas and the high job satisfaction degree among of the majority of the extension workers while the most important weaknesses were Weak budget and inadequate funding for extension work, Absence of job description for the extension workers, and Lack of financial and material resources. On the other hand the most important opportunities were Availability of research institutes in the governorate, NGO-Public Sector Collaboration. While the most important threats were Decreased investments targeting the agricultural sector in general and the extension system in particular, Poor Farmer Organization, Security instability in the governorate. Depending upon SWOT outputs, some relevant strategies were discussed to develop agricultural extension system in the governorate through some dimensions that uses strengths and opportunities to overcome weaknesses and to avoid threats or minimize their effects.
