This study demonstrated the contamination levels of polychlorinated biphenyls (PCBs), hydroxylated PCBs (OH-PCBs), polybrominated diphenyl ethers (PBDEs), methoxylated PBDEs (MeO-PBDEs), hydroxylated PBDEs (OH-PBDEs), and bromophenols (BPhs), and their relationships with thyroid hormones (THs), in the serum of human donors from an e-waste recycling site and a rural site in Hung Yen province, Vietnam. Occupationally related exposure was indicated by significantly higher residue levels of PCBs, OH-PCBs, PBDEs, and BPhs in the serum of donors from the e-waste recycling site (median: 420, 160, 290, and 300 pg g(-1) wet wt, respectively) than those in the serum of donors from the rural site (median: 290, 82, 230, and 200 pg g(-1) wet wt, respectively). On the other hand, levels of OH-/MeO-PBDEs were significantly higher in serum of donors from the reference site (median: 160 and 20 pg g(-1) wet wt, respectively) than in those from the e-waste recycling site (median: 43 and 0.52 pg g(-1) wet wt, respectively). In addition, we implemented stepwise generalized linear models to assess the association between the levels of TH and PCBs, PBDEs, and their related compounds. In females, we found positive associations of PCBs and OH-PCB concentrations with total thyroxine, free thyroxine, total triiodothyronine, and free triiodothyronine, and a negative association with thyroid-stimulating hormone concentrations.

Xây dựng quy trình định lượng flurbiprofen trong viên nénbao phim 100 mg bằng phương pháp sắc ký lỏng hiệu năng cao ghép đầu dò diode-array

Nguyễn, Thị Thanh Bình Đặng, Ngọc Anh Trần, Mai Anh Nguyễn, Thanh Hải Trong nghiên cứu này chúng tôi đã xây dựng được quy trình định lượng flurbiprofen trong viên nén bao phim 100 mg bằng phương pháp sắc ký lỏng hiệu năng cao ghép đầu dò diode-array theo hướng dẫn của Cơ quan quản lý thuốc châu Âu và Hội nghị quốc tế về hài hoà hoá các yêu cầu kỹ thuật để đăng ký dược phẩm sử dụng trên người. Pha tĩnh được sử dụng là cột silica gel pha đảo C8 (5 μm, 120 Å, 4,6×150 mm), pha động là hỗn hợp acetonitril : nước : acid acetic băng với tỷ lệ 65 : 32,5 : 2,5, tốc độ dòng 1 ml/phút. Mẫu được tiêm với thể tích 10 µl, thời gian sắc ký 8 phút, bước sóng phát hiện 247 nm. Thời gian lưu của flurbiprofen là 3,73 phút. Kết quả thực nghiệm cho thấy trong khoảng nồng độ từ 2 - 20 μg/ml, có sự tương quan tuyến tính chặt chẽ giữa diện tích pic y (mAU.min) và nồng độ dung dịch x (μg/ml) theo phương trình y = 0,680x với hệ số xác định R2 = 0,9993. Giới hạn phát hiện và giới hạn định lượng lần lượt là 0,0...

BTEX pollution caused by motorcycles in the megacity of HoChiMinh

Tran, Thi Ngoc Lan Pham, Anh Minh Monitoring of benzene, toluene and xylenes (BTEX) was conducted along with traffic counts at 17 roadside sites in urban areas of HoChiMinh. Toluene was the most abundant substance, followed byp,m-xylenes, benzene,o-xylene and ethylbenzene. The maximum observed hour-average benzene concentration was 254μg/m3 . Motorcycles contributed to 91% of the traffic fleet. High correlations among BTEX species, between BTEX concentrations and the volume of on-road motorcycles, and between inter-species ratios in air and in gasoline indicate the motorcycle-exhaust origin of BTEX species. Daily concentrations of benzene, toluene, ethylbenzene, p,m-xylenes ando-xylene were 56, 121, 21, 64 and 23μg/m3 , respectively. p,m-xylenes possess the highest ozone formation potential among the BTEX family Chi tiết xin mời tham khảo tại http://repository.vnu.edu.vn/handle/VNU_123/32862   Title:  BTEX pollution caused by motorcycles in the megacity of HoChiMinh...

Cultural Differences: A Barrier to Native English Teachers in English as a Foreign Language Contexts

Võ, Thị Hoàng Yến When teachers and students come from different cultures, many perplexities can arise. These can be due to different social positions of teachers and students in the two societies, to differences in expected teacher/student and student/student interaction, or to differences in the relevance of the curricula of the two societies (Hofstede). Therefore, it has been assumed that a teacher must be aware of socio-cultural differences to operate effectively in the classroom. This paper begins with cultural aspects of individualist and collectivist countries and influences of collectivist cultures in EFL classrooms. It also shows a number of cultural explanations of communication avoidance in EFL classrooms, especially inChina,JapanandVietnam. Finally, the paper presents some difficulties native speaking teachers encounter when teaching English in EFL contexts and potential solutions to these difficulties.
