Published: May 2021

AbstractThe research was applied in one of the farmers’ fields in Al-Khalidiyah / Anbar Governorate to determine the most appropriate traits to improve the yield of wheat grains during the two seasons 2017-2018 and 2018-2019. The experiment was carried out according to the randomized complete block design with three replicates, with aim of studying the path coefficient of the yield and its components for seven varieties of bread wheat (IPA 99, Buhooth 85, Iraq, Abu Ghraib 3, Tamoz 2, Sham 6, and Al-Rasheed). Most of the traits showed a significant positive correlation with grain yield. Also, the results of the analysis of the genetic path coefficient indicated that the indirect effect of the number of total tillers on the individual plant yield through the number of productive tillers, was 0.729 and 0.805 for the two seasons respectively, and very close to the direct effect of the number of productive tillers in the individual plant yield 0.887, 0.920. Also, the direct effect of the weight of 1000 grains on the yield of the plant was positive 0.514, 0.707, for the two seasons respectively, and its negative indirect effect of the number of productive tillers. Likewise, the direct effect was positive for the harvest index on individual plant yield and its indirect positive effect with the number of productive tillers. The study recommends focusing on breeding and improvement programs on the characteristics of the number of productive tillers, the weight of 1000 grains, and the harvest index is the best selection index to improve the cereal yield due to its significant correlation and its direct and high impact on the yield.

Abstract
Food packaging is a life necessity that has evolved and is still evolving to suit the requirements of the consumer and modern society. Commercially manufactured food cannot be processed without packaging and packaging materials, as the World Packaging Organization estimates and distributes that more than 25% of the food is lost due to poor packaging, which in turn places the burden on packaging to reduce the great loss of food through the continuous development of packaging materials. And methods in proportion to the food product. The use of renewable edible agricultural materials which major role in the food industry has increased because the development in technologies to improve the properties of edible polymers is the main issue in future research. Most of the studies today are focused on extending the shelf life of food in the applications of biological or biological membranes and covering food with the most important advantages of edible films that have aroused consumer interest, which are made of natural edible materials, non-toxic and non-polluting to the environment compared to plastic films and increase The nutritional value when present as a film over the food and controlling the water content in the food wrapped in it, whether in not absorbing or losing moisture, as well as protecting it from the absorption or loss of flavors and does not require expensive techniques and thus reduce the production cost and the cost of treating environmental pollution implicitly without. The presence of residues for packaging when used, in light of the wide range of food products such as meat (fish, poultry, beef) and other foods that are very sensitive to fat oxidation and microbial contamination, these products are considered to have edible, antioxidant and microbial membranes very important in their protection targeting innovative trends. In the field of food packaging research in introducing improvements in food quality and safety and increasing the shelf life or period validity as well as quality control based on equipment and international quality standards, where strategies in packaging represent the development of multi-functional packaging materials based on the use of renewable biodegradable materials and natural additives as well as their traditional packaging functions (containment, protection, marketing, provision, consumer.

Authors: Lu Weiping , Chen Zhisheng , Wu Rongpeng , Zhang Zhichao 
Published: May 2021

Abstract
After the investigation of a foundation pit project and the preliminary determination of the precipitation design scheme, the distribution of water level drawdown and land subsidence in the whole site was simulated by Visual Modflow software. The simulation results show that by setting the pump output of the 14 confined dewatering wells in the pit varying from 70 ~ 420 m3/day, the drawdown of the foundation pit can be uniformly reduced to about 4m. Due to the waterproof curtain, the waterline distribution inside the foundation pit is relatively uniform, which proves the rationality of the setting of the pumping well. At the same time, the waterline contour around the edge of the curtain is very intensive, indicating that there is huge difference in the drawdown between inside and outside of the waterproof curtain. The curtain plays an effective role in controlling the drawdown inside and outside the pit foundation, hence, the compression deformation and settlement of the soil are also small so as to avoid the damage of the surrounding buildings due to the uneven settlement of the ground surface. Therefore, the precipitation design has achieved a good effect.
Research on the Influence of Reservoir Physical Property Time Change on Reservoir Water Drive Development
Authors: Ding Xiaohui 
Published: May 2021

Abstract
With the continuous development of China’s social economy, the total demand for energy in China’s industrial production is constantly increasing, among which petroleum energy is an important energy type needed in industrial production. China’s petroleum energy mainly depends on imports, which is very unfavorable to China’s economic development and energy security strategy. Therefore, it is necessary to improve China’s oil exploitation efficiency, increase oil production and alleviate China’s energy shortage. In this paper, the influence of time variation of reservoir physical properties on reservoir water flooding development is deeply studied and analyzed, and some reasonable suggestions and measures are put forward to further promote the development of China’s petroleum development engineering industry. In the oil field developed by water flooding, the long-term scouring force of water will lead to a series of complex physical and chemical changes in the microscopic space of oil reservoir, which will lead to certain changes in the physical parameters of oil reservoir. This phenomenon is called time-varying physical properties. Time-varying physical properties are the main factors affecting reservoir exploration and development, so it is necessary for staff to grasp the relevant technical key points, so as to make clear the changes and the changed reservoir physical parameters. According to the changes, the subsequent work will be adjusted accordingly. Time-varying reservoir will affect the movement law of oil and water in the reservoir, thus affecting the actual development effect of the reservoir, and also affecting the distribution of remaining reservoirs after reservoir development.

Published: May 2021

Abstract
The decoupling of economic growth and heavy metal water pollution discharge in the Yellow River Basin is conducive to the coordinated promotion of large-scale governance. Although there are abundant researches on the decoupling elasticity of resource and environment consumption and its driving effect, there are few microscopic analyses on the driving effect. In view of this, Tapio and LMDI model for the Yellow River basin in 2011-2017 economic growth and heavy metal water pollutants decoupling state and driving effect, explain the decoupling mechanism of heavy metal discharge in the Yellow River basin. The results show that : (1) Although there is a strong decoupling state at the basin level (except 2014-2015), the decoupling situation in the upstream region is still very unstable. (2) The sewage discharge intensity effect is the dominant effect driving the discharge decoupling of heavy metal water pollutants in the basin; The income effect of industrialization is the dominant effect of restraining the decoupling of heavy metal water pollutant discharge.
