Water Salinity Evaluation Suitability for Settlement After Ten Year Tsunami in Banda Aceh, Indonesia

Banda Aceh is a residential area that is most severely impacted by the earthquake and tsunami on December 26, 2004. Recently, ten years after the incident, many settlements were rebuilt. As a disaster-prone areas, Banda Aceh would need to be evaluated against the settlement area base on water salinity. The focus of the study centered on the application of geographic information systems in handling spatial data bearing capacity of the land into the concept of the FAO land suitability. To ensure the application works, it requires geospatial analysis compiled based on the salinity of the water variables that can be observed and measured for the residential requirements. The results showed that 86 percent (ordo S) suitable for residential areas and 14 per cent (ordo N) is not suitable.Banda Aceh adalah daerah pemukiman yang paling parah terkena dampak gempa dan tsunami pada 26 Desember 2004. Baru-baru ini, sepuluh tahun setelah kejadian tersebut banyak pemukiman yang dibangun kembali. Sebagai daerah rawan bencana, evaluasi terhadap kadar salinitas pada basis kawasan pemukiman di Banda Aceh perlu dievaluasi. Fokus dari penelitian ini berpusat pada aplikasi sistem informasi geografis dalam penanganan data spasial terhadap dukung data tanah sesuai dengan konsep kesesuaian lahan FAO. Untuk memastikan aplikasi tersebut sesuai, analisis geospasial disusun berdasarkan variabel salinitas air yang diamati dan diukur sebagai persyaratan pembangunan pemukiman. Hasil penelitian menunjukkan bahwa 86 persen (ordo S) cocok untuk daerah pemukiman dan 14 persen (ordo N) adalah tidak cocok

Evaluation of innovative cotton genotypes against insect pest prevalence, fiber trait, economic yield and virus incidence in Pakistan

Cotton (Gossypium hirsutum) is known as important commodity globally. The experiment was conducted at Cotton Research Station, Multan, Punjab-Pakistan, to evaluate resistance of nine innovative cotton cultivars against insect pest complex were used along with their fiber traits, economic yield and virus incidence. Population of jassid, whitefly and thrips was recorded by using leaf turn method, bollworms by counting whole fruiting parts (buds, flowers and bolls), virus by counting healthy and virus effected plants per plot, yield of seed cotton was determined by hand harvesting method, while qualitative fiber properties were measured through HVI spectrum-1 (high volume instrumentation) method. Cotton genotype NIAB-Bt-2 is resistant to jassid, whitefly and thrips with maximum GOT, staple length. In case of bollworms, all genotypes are resistant to spotted and american bollworm, except FH-142 and MNH-988. No genotype is resistant to pink bollworm in leftover bolls. Best yield performance was recorded on FH-142 (2041.54 kg/ha) with minimum CLCuV incidence. Further our research should recognize the share of one pest species on the yield and fiber quality of cotton by managing other pest species to define better management strategies. Our studies concluded that the genotype NIAB-Bt-2 has less insect attack i.e., sucking pest as well as bollworms, virus and other fiber characteristics like GOT, staple length as compared with other cotton genotypes should be recommended for general cultivation and being a resistant germplasm it should be included in breeding program for the development of new cotton strains

Fisheye Consistency: Keeping Data in Synch in a Georeplicated World

Over the last thirty years, numerous consistency conditions for replicated data have been proposed and implemented. Popular examples of such conditions include linearizability (or atomicity), sequential consistency, causal consistency, and eventual consistency. These consistency conditions are usually defined independently from the computing entities (nodes) that manipulate the replicated data; i.e., they do not take into account how computing entities might be linked to one another, or geographically distributed. To address this lack, as a first contribution, this paper introduces the notion of proximity graph between computing nodes. If two nodes are connected in this graph, their operations must satisfy a strong consistency condition, while the operations invoked by other nodes are allowed to satisfy a weaker condition. The second contribution is the use of such a graph to provide a generic approach to the hybridization of data consistency conditions into the same system. We illustrate this approach on sequential consistency and causal consistency, and present a model in which all data operations are causally consistent, while operations by neighboring processes in the proximity graph are sequentially consistent. The third contribution of the paper is the design and the proof of a distributed algorithm based on this proximity graph, which combines sequential consistency and causal consistency (the resulting condition is called fisheye consistency). In doing so the paper not only extends the domain of consistency conditions, but provides a generic provably correct solution of direct relevance to modern georeplicated systems

Construction procurement in industrialised building system

The government, through CIDB Malaysia have continuously promoting Industrialised Building System (IBS) to increase the immense efficiency of the building performance structure. However, the level of IBS adoption among the construction players in Malaysia is still low and far from the government expectation. It is evident that most of the IBS projects developments in Malaysia are still conducted by using the conventional procurement method. This creates a number of issues such as reworks, time delay, rising cost, lack of communication and integration problem. Thus, this paper will identify existing procurement process used for IBS projects in Malaysia construction industry. Identifying existing procurement process helps in providing significant elements before creation of a more effective new procurement for IBS projects in Malaysia. Expert interviews was used, whereby 5 (five) interviews sessions were conducted with IBS experts in Malaysia construction industry. Thematic analysis was utilised to analyse the interview result by identifying the existing procurement process adopted in current IBS projects. Findings from expert interviews showed that there are three different procurement process commonly applied in current IBS projects. Result also shown that one of the significant barriers to IBS adoption is the current practice of procurement and team integration. Therefore, a more effective new procurement for IBS projects should be considered and pursued urgently in order to improve IBS implementation in the Malaysian construction industry

A Phytochemical Analysis, Microbial Evaluation and Molecular Interaction of Major Compounds of Centaurea bruguieriana Using HPLC-Spectrophotometric Analysis and Molecular Docking

Centaurea is one of the most important genera within the family Asteraceae. An investigation of the phytochemical composition of Centaurea bruguieriana using Gas-Chromatography coupled to Mass spectrometry (GC-MS) was performed. Antimicrobial activity was evaluated using the minimum inhibitory concentration method (MIC) and validated by molecular docking for the major compounds of the most active fraction (1,10-di-epi-cubenol and methyl 8-oxooctanoate) of C. bruguieriana against three bacterial receptors (TyrRS, DNA gyrase, and dihydrofolate reductase (DHFR)). Evaluation of antioxidant activity was conducted using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. High-performance liquid chromatography (HPLC) was used to identify and quantify the contents of major compounds from ethyl acetate fraction (luteolin 7-O-glucoside, chlorogenic acid, kaempferol and isorhamnetin). The antimicrobial activity test showed that the chloroform fraction was more active against all microbial strains. The results of the molecular docking of two major compounds from chloroform fraction showed that good affinities were made between 1,10-di-epi-cubenol and the three selected receptors (TyrRs: −6.0 Kcal/mol against −8.2 Kcal/mol obtained with clorobiocin (standard); DNA gyrase: −6.6 Kcal/mol against −9.1 Kcal/mole obtained with clorobiocin; DHFR: −7.4 Kcal/mol against −6.3 Kcal/mol obtained with SCHEMBL2181345 Standard). Antioxidant evaluation showed that the ethyl acetate fraction was the most active fraction in DPPH (IC50 49.4 µg/mL) and ABTS (IC50 52.8 µg/mL) models. HPLC results showed the contents of luteolin 7-O-glucoside (7.4 µg/mg), and chlorogenic acid (3.2 µg/mg). Our study demonstrated that C. bruguierana is a promising source of bioactive compounds
