Use of recurrent selection in middle late synthetic maize populations. results of the first cycle in synthetic “1/2017”

The present study shows the results of a completed first cycle of recurrent selection in a middle late synthetic population “1/2017” and the inbred lines PAU 1617 and B 113 are used as a recurrent parents. The aim of the improving selection is to obtain from the synthetic inbred lines which are later to be used as parental forms for receiving hybrids of this maturity group. The experimental work was carried out in the period 2017 – 2019 when two hundred and ten testcrosses were tested. After the data was analyzed, eighty even inbred progeny variants displaying the best results have been included for crosspollination and a new cycle of breeding. The genetic variability in the synthetic has been preserved as the selected progeny represent 41,4 % of the initially chosen ones. The index of variability after recurrent selection is 12,2 % which allows for efficient testing in the subsequent stages of the improving selection. As a direct outcome of the research, thirteen crosses have been pointed out – B 113 x 37/1, B 113 x 25/5, PAU 1617 x 71/3, B 113 x 29/1, B 113 x 33/1, PAU 1617 x 97/3, PAU 1617 x 85/3, B 113 x 71/5, B 113 x 71/6, B 113 x 53/1, B 113 x 55/1, B 113 x 77/3 and B 113 x 43/1. They exceed in grain yield the foreign standard in the maturity group respectively with 25.2, 20.0, 16.9, 16.6, 15.1, 15.0, 13.1, 12.5, 10.5, 9.0, 8.8, 8.8 and 8.2%. They are still tested in varietal and ecological trials.

GIST ĐẠI TRÀNG Ở TRẺ EM: BÁO CÁO CA BỆNH VÀ TỔNG QUAN Y VĂN

Mục đích: Báo cáo ca bệnh hiếm gặp u mô đệm ống tiêu hoá (GIST) của đại tràng ở trẻ em. Phương pháp: Báo cáo ca bệnh và tổng quan y văn. Kết quả: Bệnh nhân (BN) nữ 13 tuổi vào viện vì đau bụng cơn, nôn, đại tiện phân máu. Siêu âm ổ bụng phát hiện khối lồng ruột đại- đại tràng, vị trí hạ sườn trái, kích thước 54 x 43 x 51mm. Cắt lớp vi tính thấy khối lồng với tổ chức nghi u đại tràng xuống. Nội soi đại tràng thấy u đại tràng xuống kích thước 40 x 30mm, có hoại tử trung tâm. BN được phẫu thuật nội soi cấp cứu tháo lồng ruột. Sau phẫu thuật 1 ngày BN bị lồng ruột tái phát với các triệu chứng tắc ruột, được phẫu thuật cấp cứu cắt đoạn đại tràng trái với mép cắt cách khối u 3-5cm. Kết quả giải phẫu bệnh là u GIST và diện cắt vi thể không có tế bào u. Sau mổ bệnh nhân hồi phục tốt, ra viện sau mổ 7 ngày. Theo dõi 3 năm không có biến chứng và không thấy u tái phát hay di căn. Kết luận: U GIST đại tràng hiếm gặp ở trẻ em. Phẫu thuật triệt căn cắt đoạn đại tràng với mép cắt trên và dưới âm tính là phương pháp điều trị hiệu quả trong bệnh lý này trong giai đoạn u tại chỗ.

Spatial Variability of Atmosphere Dust Fallout Flux in Urban–Industrial Environments

This work aimed to assess and characterize the air quality in what concerns particulate pollution in urban–industrial environments. The main objectives were to study the spatial variability of the deposition flux of particulate pollution identifying areas with higher deposition and to associate the variability with climatological variables and with possible surrounding emitting sources. The method for collecting the deposited particles was based on the standard NF X 43–007. Sampling for particulate pollution took place between April 2015 and February 2016 through seven sampling campaigns. Maps of the spatial dispersion for the particulate pollution were obtained through statistics and geostatistics techniques. Elemental identification by scanning electron microscopy (SEM) was also used but only in two sampling campaigns. The results show that the sampling campaigns that took place during hot and dry periods, 2nd and 3rd, present higher deposition flux: 2.04 g/(m2 × month) and 1.72 g/(m2 × month), respectively. Lower deposition fluxes were registered in the 6th and 7th campaigns: 0.23 g/(m2 × month) and 0.24 g/(m2 × month), respectively. A recurrent high deposition was also observed at specific sampling points that may be due to both the nearby road traffic and the presence of chimneys. SEM analysis allowed to associate repetitive element deposition, at the same sampling point, to the same emitting source.

Ms X., 43 y., Multipara, always in good health, told Dr Jacobs: six months ago she felt pains in the ovarian region, which intensified with the passage of time; the stomach gradually increased in volume. Other painful symptoms appeared: sleeplessness, lack of appetite, obstructed defecation, and urination. External examination: the abdomen is significantly increased in volume and a tumor is felt in the lower part; accumulation of fluid in the abdominal cavity.
