Abstract
The aim of this study was investigate the effect of adding aqueous extract of green tea on some chemical properties (thiobarbituric acid TBA, total volatile nitrogen TVN, free fatty acid FFA, and peroxide value PV) on sheep meat stored for 0, 3, 6, 9 and 12 days at 1-4 Cº. The treatments included: the first treatment was a control treatment without addition (0 %). As for the second, third, fourth and fifth treatments, green tea leaf aqueous extract was added by 0.5, 1, 1.5 and 2% respectively. The results of the study showed a significant decrease for (T.B.A, T.V.N, F.F.A, and P.V) compared with control treatment for all periods. The TBA concentration decreased significantly for the fifth treatment, compared the first treatment which had the highest concentration. As for the addition treatment, the fifth treatment showed a significant decrease for all the periods . As for T.V.N, its value decreased significantly for the fifth treatment (7.01%) at the day 12 of storage period . While the first treatment had the highest (P≤0.01) concentration value of 14.72% for the same storage period. The concentration of P.V decreased significantly for the fifth treatment, (4.22%) for the last storage period (12 days), while the first treatment recorded the highest (P≤0.01) value (6.31%) for the same period of storage. With these results, green tea leaf extract can be used as a natural antioxidant to store meat for long periods in cold storage or to extend the shelf life in term of TBA, TVN, FFA and PV.

Abstract
Eggs are inexpensive nutrition source and consist of fat soluble vitamins. Vitamin E, selenium and zinc are found in a small amount in eggs. Alfalfa is an inexpensive natural source of vitamin E, selenium and zinc. Therefore, a study was conducted to evaluate the effects of dried alfalfa in a ratio of 0%, 2%, 4%, 6%, 8% and 10% in diet additive on the increase ratio of vitamin E, selenium and zinc in eggs. In this experiment, a total of 180 birds (aged 27 weeks) were ranged in 6 treatments over three replicates including 10 birds of ISA-BROWN layer in each treatment. During the 17 weeks’ experiment period (two weeks of preliminary period), the experimental results showed a significant increase in vitamin E, selenium and zinc contents. A proportional increase in the ration of vitamin E, selenium and zinc were recorded with the increase of the ration of the dried alfalfa additive in the diet. The highest ratio of the dried alfalfa (10%) showed the highest increase in the vitamin E, selenium and zinc. Moreover, no significant differences were recorded between the treatments in term of egg production performance.

Abstract
Traditional road quality inspection is time-consuming, laborious and not highly accurate. As a new type of non-destructive detection tool, Ground Penetrating Radar (GPR) has the advantages of fast, efficient, continuous, simple and accurate operation, and is widely used. This research uses GPR to conduct non-destructive testing of cement road in a cold storage base to detect quality problems such as road diseases. Through detection, it was found that the cold storage base had no obvious cavities within 10m depth in the detection area, but there was a phenomenon of incompact and loose water accumulation. The foundation should be strengthened during construction. The thickness of the cement road was uniform, and its construction quality was good. Through on-the-spot detection, it provides reference for the ground-penetrating radar non-destructive detection of concrete roads and disaster warning.

Published: May 2021

Abstract
Surface well extraction is an important part of coalbed methane development in coal mine area. Taking the 1303 (lower) fully mechanized working face of Yuecheng coal mine as the research object, considering the characteristics of coal and rock accumulation in the three areas of goaf, this paper uses COMSOL numerical software to simulate and analyze the gas migration characteristics of the goaf where the surface wells are located along the strike and inclination of the working face. The results show that the gas concentration in goaf decreases gradually with the progress of drainage, and surface wells in different shaft location basically reach the balance in about 2000s. The shaft location of the surface well and the gas concentration in the upper corner are exponential function. In order to ensure the safety of coal production, the distance between the well distribution and the working face should be controlled within 240m, and close to the area near the return air lane. The research results provide a reference for the selection of surface well location.

Abstract
In order to solve the problem of rapid increase in water content and decrease in production after water flooding in fault block reservoirs, the air foam flooding experiments of static low temperature oxidation, single and double sand filled tube were carried out. The results showed that there was no absolute relationship between oxygen consumption and viscosity of crude oil, and there was a turning point of water saturation. The reaction rate is greatly affected by the reaction temperature. The displacement efficiency of single pipe is increased about 15%. The injection of air foam can effectively block the high permeable strip, and the middle low permeability layer is effectively utilized, and the recovery ratio is increased by about 10.9%. The plan of air foam flooding for Gao 16 block is compiled. The injection volume is 0.1PV and the gas-liquid ratio is 2:1. The recovery factor is increased by 5% and the cumulative oil increment is 22700 tons.

Study on the Minimum Flowing Pressure Boundaries of Different Reservoirs in SZ Development Zone
Authors: Wang XiaoLei 
Published: May 2021

Abstract
Reasonable bottom-hole flow pressure is the guarantee for giving full play to oil well productivity and improving oilfield development efficiency. In the actual production process of the oilfield, when the bottom hole flow pressure is reduced to a certain extent, the liquid production of the oil well start to decrease, and there exist a maximum production point in the oil well. To study the minimum bottom-hole pressure limits of different water cut stages in SZ development zone, the inflow dynamic analysis model of oil well is put forward. By considering the influence factors of bottom hole flow pressure change, such as water cut, dissolved gas coefficient, saturation pressure and formation pressure change, the minimum allowable bottom hole flow pressure of SP oil layer is 1.5-2 MPa, and GTZ oil layer is 2-2.5 MPa. The proposed boundary model of bottom hole flow pressure provides theoretical guidance for reasonable flow pressure design and production allocation of oil wells.
