Grain Filling Stage

Based on the experiment of two inbred aromatic rice varieties and one hybrid aromatic rice line treated under four different temperatures( daymean temperature 21°C, 23°C, 26°C and 30°C respectively) during grain filling stage in phytotrons, the shape and arrangement of endosperm starch granules in rice grain transection were observed by scanning electron microscope and the related characteristics of rice grain qualities of chalky percent and chalkiness were analyzed at the same time. The results showed that under the lower temperature( daymean temperature21°C and 23°C), many large compound starch granules with clear angulars packed together regularly without significant natural gaps bewteen starch granules in the tansectional endosperm. However, with the increase of temperature, starch granules in the transectional endosperm were changed from regularly shaped and closely and orderly arranged to various shaped and chaoticly arranged with obvious natural gaps between starch granules, which was closely consistent with the poorer appearance quality under the higher temperature, which indicated that the endosperm structure is closely related with appearance quality of aromatic rice.

Статья посвящена анализу и изучению различных способов получения нефтяных битумов и улучшения адгезионных свойств в различных минеральных материалах. На примере Астраханского газоперерабатывающего завода показана эффективность добавления присадок - азот-, серосодержащих веществ, элементной серы и др. для улучшения адгезионных свойств битумов к минеральным материалам. Проведен анализ воздействия перепада температур в летнее и зимнее время на вяжущие свойства битумов. Рассмотрен способ предварительной отгонки летучих компонентов из нефтей, что приводит к уменьшению содержания парафинонафтеновых углеводородов и улучшению качества получаемых битумов. В статье также приведены результаты экспериментальных исследований влияния окисления кислородом воздуха, повышения температуры процесса на пластичность битумов. Эффективность окисления битумов зависит от величины поверхности контакта между жидкой и газовой фазой. Ускорение процесса окисления достигается в 6-7 раз при хорошем перемешивании реагирующих фаз. The article also presents the results of experimental studies of the effect of oxidation with atmospheric oxygen, an increase in the process temperature on the plasticity of bitumen. The efficiency of bitumen oxidation depends on the size of the contact surface between the liquid and gas phases. Acceleration of the oxidation process is achieved 6-7 times with good mixing of the reacting phases.The article is devoted to the analysis and study of various methods of obtaining petroleum bitumen and improving the adhesion properties in various mineral materials. Using the example of the Astrakhan gas processing plant, the effectiveness of the addition of additives - nitrogen-, sulfur-containing substances, elemental sulfur, etc. - to improve the adhesion properties of bitumen to mineral materials is shown. The analysis of the effect of temperature differences in summer and winter on the binding properties of bitumen is carried out. A method for preliminary stripping of volatile components from oils is considered, which leads to a decrease in the content of paraffin-naphthenic hydrocarbons and an improvement in the quality of the obtained bitumen.

The objective of the present study was to determine the drying kinetics, moisture diffusivity and sensory quality of convective air dried beef. The effect of temperature of drying (30-60°C) and thickness of samples (2.5-10 mm) on the convective thin-layer drying kinetics of beefdried in a cabinet dryer was evaluated. Five semi-theoretical models were fit to the drying experimentaldata with the aim of predicting drying characteristics of beef and fitting quality of models determined using the standard error of estimate (SEE)and coefficient of determination (R2). Determination ofeffective moisture diffusivity (Deff) from the experimental drying datawas done and sensory quality of the optimized dried cooked and uncookedbeef samplesevaluated. Drying time and rate of drying increased with an increasing temperature but decreased with increased slice thickness. However, there was overlapping of drying curves at 40-50°C. Among the selected models, Page model gave the best prediction of beef drying characteristics. Effective moisture diffusivity (Deff) ranged between 4.2337 x 10-11 and 5.5899 x 10-10 m2/s, increasing with an increase in air temperature and beef slice thickness.Of all the sensory parameters evaluated, texture was the only attribute that gave significantly different (P > 0.05) scores between the cooked and uncooked dried beef samples.

Aluminium-reinforced composites play a vital role in the engineering industry because of their better strength and stiffness. The properties are directly related to the solidification phenomenon of the cast alloy. The design engineer should understand the importance of the solidification behavior of base alloy and its reinforcement. Composites’ solidification study is rare, and the reviews are limited. The solidification process is analyzed using the finite element method (FEM), and this would fetch a lot of information about the cooling rate of the composites and also helps to reduce the time in experimentation. This paper reports and plots the cooling curves of Al/SiCp composites using simulation software. Cylindrical-shaped composites were developed using the squeeze casting method, and the experimental cooling curves were plotted using a K-type thermocouple. Composites samples were prepared at the following squeeze pressures: 0, 30, 50, 70, 100, and 130 MPa; melt and die temperature was kept constant at 800 and 400°C, respectively. The experimental and FEA cooling curves were compared, and it was agreed that the increase in the squeeze pressure increases the cooling rate of the developed composite. Furthermore, the effect of temperature distribution from the inner region of the melt and die material which causes the radial and tangential stress of components has also been examined.
