Manganese (Mn) and iron (Fe) are the two vital micronutrients for plants and moreover essential nutritional health components in humans. Iron deficiency is common in humans and causes many health issues. In this survey, wheat grains of two major wheat cultivars were analyzed for their Mn and Fe concentrations beside the natural gradient of micronutrient availability across Sulaymaniyah province, Iraqi Kurdistan. However only 20% and 7.5% of the soils samples were Mn and Fe deficient or below recommended level. The considered micronutrient concentrations in the grains of wheat were in the acceptable range which are reported globally (range 41.3 and 37.6 mg kg-1 respectively). Furthermore, high application of nitrogen and phosphorus fertilizer in the studied calcareous soils could be strongly affected on the studied micronutrients concentration in the studied grain samples. The results indicate that adequate levels of Mn and Fe in the surveyed grains is a beneficial guide for quality of grains associated with human healthiness, where wheat grain bread is an essential food.

Ohmic heating is a unique thermal technology in which an electrical current is passed through a food product, causing heat to be generated. This alternative heating process was investigated in terms of energy efficiency and high quality method for a batch quantity of whole cow milk. The study's major goal is to show that it is possible to develop a heater that successfully pasteurizes milk on a laboratory scale. Before and after ohmic and conventional heating procedures, chemical characteristics (such as protein, acidity as lactic acid, fat, and solid non-fat), alkaline phosphatase, and microbial counts (such as total bacteria count and E. coli) of the milk were examined. When the maximum voltage gradient (19.13 V/cm) was used, the protein content of pasteurized milk remained unaltered. The fat level remained consistent at 5.10 % across all pasteurization methods. Both conventional and ohmic heating inactivated alkaline phosphatase and microorganisms. Different voltage gradients of 6.08 V/cm, 9.56 V/cm, and 19.13 V/cm were also studied to see what effect they would have on the ohmically heated milk's electrical properties (such as electrical conductivity and current).

Article information The conversion of electrical energy into heat energy, which results in internal energy generation, is the underlying premise of Ohmic heating. An experimental batch Ohmic heating unit was built and manufactured for this study. The effect of voltage gradient of alternating current during batch Ohmic heating on orange juice was investigated. Parameters such as temperature, electrical current, time consumption, system performance coefficient, and heating rate of orange juice under Ohmic heating process were studied. The time consumption such as (23.02, 11.25, and 2.19 minutes) to reach the Ohmic pasteurization temperature (95 °C) was decreased as the voltage gradients (9.20 V/cm, 12.64 V/cm, and 25.28 V/cm) increased respectively. The electrical current was rapidly increased (4.46 Amp.) in accordance with the higher voltage gradient (25.28 V/cm) to attain the pasteurization temperature. With rising voltage gradients, Ohmic heating resulted in greater system performance coefficient values. The heating rate appears to have grown dramatically as the voltage gradients increased.

In animal breeding, linear body measurements are identified as predictors of body weight. The current study was conducted to estimate body weight (BW) by using body measurements including thoracic circumference (TC), withers height (WH), body length (BoL), rump height (RH) and front leg length (FLL) of donkeys. The study was conducted at three villages (Thorne, Archibalt, and Genau) of Blouberg Local Municipality, Limpopo, South Africa. A total of 74 donkeys (40 males and 34 females) aged from 3 to 4 years were used in the current study. Data were analyzed using Pearson correlation and simple linear regression. Correlation results indicated that in female donkeys, BW had positive and highly statistical significant (p 0.01) correlation with WH (r = 0.67) and not significant correlated (p 0.05) with TC (r = 0.14) and FLL (r = 0.28). In male donkeys, BW had positive and highly statistical significant (p 0.01) correlation with RH (r = 0.60) and not significant correlated (p 0.05) to FLL (r = 0.27).
