Published: September 2019

Thiết kế chiếu sáng tự nhiên cho công trình đóng một vai trò rất quan trọng đối với tiện nghi thị giác của con người, nâng cao hiệu suất lao động và tiết kiệm năng lượng cho công trình. Cho đến nay việc tính toán thiết kế chiếu sáng tự nhiên ở nước ta đang dựa trên mô hình bầu trời đầy mây CIE. Mô hình bầu trời này đặc trưng cho các nước ôn đới có thời gian mùa đông dài, không đặc trưng cho bầu trời nhiệt đới như Việt Nam, nơi mà độ rọi trên mặt ngang ngoài nhà và độ chói do bầu trời gây ra rất lớn. Vì vậy cần thiết phải nghiên cứu và cập nhật lý thuyết trong tính toán và thiết kế chiếu sáng tự nhiên. Nghiên cứu này đề xuất các phương pháp mới phân tích sự phân bố độ chói của bầu trời nhiệt đới Việt Nam và xác định hệ số phân bố không đồng đều độ chói q cho hai thành phố Hà Nội và TP. Hồ Chí Minh dựa trên số liệu khí hậu ánh sáng của Việt Nam, bằng 2 phương pháp: 1) phương pháp sử dụng 15 mô hình bầu trời được đề xuất bởi Kittler; 2) phương pháp sử dụng hệ số mây Ko (tỉ số giữa độ rọi ngang tán xạ và độ rọi ngang tổng xạ). Kết quả nghiên cứu cũng chỉ ra sự khác biệt của các giá trị hệ số phân bố không đồng đều độ chói q khi tính toán với mô hình bầu trời đầy mây và bầu trời nhiệt đới thưc tế ở Việt Nam. Phương pháp nghiên cứu này có thể sử dụng được cho nhiều vùng khí hậu khác nhau.

Singapore's Lost Coast: Land Reclamation, National Development and the Erasure of Human and Ecological Communities, 1822-Present
Authors: Powell Miles Alexander 
Published: September 2019

Abstract
Beginning during the colonial period, and greatly accelerating following independence in 1965, Singapore has used land reclamation to increase its national domain by nearly 25 per cent. The construction of new land was a key component of the nation's celebrated rise from 'third world' to 'first world' in the postcolonial period. But the economic benefits of remaking Singapore's coastline came at significant ecological and social costs. Nearly all of the original shore, and its attendant mangrove forests and natural beaches, were lost. So too were two-thirds of Singapore's coral reefs. While carrying out this reclamation, the state also erased a number of sites at which people made a living from the sea, including indigenous communities on the outer islands, age-old fishing villages, kelongs (large, traditional offshore fishing platforms) and prawn farms.
The history of land construction in Singapore offers a number of important insights concerning the relationship between humans and our environments. First, it reveals how the tensions between an ideal situation (a city or state's relationship to other places) and a less than optimum site (its physical environment), when combined with a forceful, proactive government, can bring about immense environmental transformations. Related to that, this case sheds light on the ways in which governments - especially in developing nations - can use transformation of terrestrial and marine environments, in the name of progress, as a means of expanding and legitimating their authority. This history also reveals a perhaps unforeseen consequence of bulldozing and burying sites at which humans derived their livelihood from living oceanic resources: the loss of a cultural connection to the sea, based on knowing nature through work. Finally, this history raises the question of how environmental advocates can pursue conservation in a setting like Singapore's shores, which we can no longer consider pristine or natural. That is to say, the ongoing efforts of environmentalists to protect flora and fauna in Singapore's waters speak to the necessity of, and challenges presented by, preserving hybrid (neither entirely natural nor entirely artificial) marine environments.

Abstract. The objectives of this research was to study the macroscopic, the microscopic and phytochemicals characterization of raw materials, total polyphenol content and the antibacterial activity of nut grass extracts (Cyperus rotundus L.) against Shigella dysenteriae, Salmonella typhimurium, Staphylococcus epidermidis, and Pseudomonas aeroginosa. The macroscopic and the microscopic characterization of raw materials were done with the determination of the water contents, the water soluble contents, the ethanol soluble contents, total ash and acid soluble ash. The extract was prepared by percolation using n-hexane, ethanol, and ethyl acetate as solvents. Phytochemical screening was done on the raw materials as well as n-hexane, ethyl acetate, and ethanol extracts. Total phenol contents were tested with the Folin-Ciocalteu reagent method. The antibacterial activity test was done by measuring the diameter of the inhibition zones using the diffusion agar method. The results showed that raw material retrieved 7.33% water content, 21.85% water soluble contents, 7.9% ethanol soluble contents, 1.53% total ash, and 0.67% total insoluble-acid ash. The phytochemical study showed that the nut grass contains various secondary metabolites including flavonoids, glycosides, saponins, anthraquinone glycosides, and steroid/triterpenoids. The total polyphenol contents of ethanol extracts were expressed as catechin equivalents 1.1616 mg/g extract. All of the nut grass extract showed antibacterial activity. Ethyl acetate extract of nut grass indicated the highest antibacterial activity against Shigella dysenteriae, Salmonella typhimurium, and Pseudomonas aeroginosa. Ethanol extract was only effective against Staphylococcus epidermidis.
