Characteristics and adsorption performance of formulated trikotaC filter aids

TrikotAC filter aids is a combination of a pre-coating material PreKot™ with two adsorbents; activated carbon and lime and their characteristics were investigated in this study. TrikotAC was formulated into three different weight ratios of 5:1:94, 10:1:89 and 10:5:85, respectively. The relationship between adsorption properties and characteristics of the formulated materials particle size distribution, particle density, bulk density, and BET surface area were investigated. The results showed that the adsorption capacity for TrikotAC 10:5:85 (11.88 mg/g) was higher than for the other formulated filter aids samples, and the formulated filter aids material TrikotAC showed promising characteristic as a filter aids and adsorbent for organic compound in fabric filtration system

Pemanfaatan Lidar untuk Evaluasi Ketinggian Bangunan di Kawasan Jalan Pandanaran, Semarang

Kota Semarang merupakan ibukota Provinsi Jawa Tengah sekaligus kota metropolitan terbesar kelima di Indonesia setelah Jakarta, Surabaya, Medan dan Bandung. Kota Semarang terus mengalami perkembangan dan pembangunan kota. Perkembangan dan pembangunan kota yang terjadi menyebabkan berdirinya bangunan gedung secara pesat. Oleh karena itu, pembangunan di Kota Semarang membutuhkan pengontrolan terhadap kesesuaian penataan ruang yang ditetapkan oleh Pemerintah Daerah. Penataan ruang merupakan suatu sistem perencanaan dan pemanfaatan ruang yang perlu dikendalikan dalam proses pengembangan suatu kawasan. Penelitian ini berfokus pada tinggi bangunan gedung di kawasan Jalan Pandanaran Kota Semarang, dengan melakukan evaluasi terhadap Peraturan Daerah (Perda) Kota Semarang Nomor 14 Tahun 2011 dan Peraturan Menteri Perhubungan Nomor KM 35 Tahun 2008. Penelitian ini menggunakan pendekatan data DEM LiDAR untuk memperoleh tinggi bangunan secara aktual. Tinggi bangunan yang melebihi ketentuan dari Peraturan Daerah (Perda) Kota Semarang Nomor 14 Tahun 2011 dan Peraturan Menteri Perhubungan Nomor KM 35 Tahun 2008 dianggap sebagai bangunan melanggar. Pelanggaran tersebut terjadi pada 3 bangunan gedung, yaitu Bank Panin, Louis Keinne Hotel, dan Menara Suara Merdeka. Nilai pelanggaran yang terjadi untuk ketinggian bangunan di Kawasan Jalan Pandanaran sebesar 2,65 %. Maka nilai kesesuaian hasil evaluasi tinggi bangunan tersebut mencapai dari 97,35 %

Analysis of Physiochemical Parameters to Evaluate the Drinking Water Quality in the State of Perak, Malaysia

YesThe drinking water quality was investigated in suspected parts of Perak state, Malaysia, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a detailed physical and chemical analysis of drinking water samples was carried out in different residential and commercial areas of the state. A number of parameters such as pH, turbidity, conductivity, total suspended solids (TSS), total dissolved solids (TDS), and heavy metals such as Cu, Zn, Mg, Fe, Cd, Pb, Cr, As, Hg, and Sn were analysed for each water sample collected during winter and summer periods. The obtained values of each parameter were compared with the standard values set by the World Health Organization (WHO) and local standards such as National Drinking Water Quality Standard (NDWQS). The values of each parameter were found to be within the safe limits set by the WHO and NDWQS. Overall, the water from all the locations was found to be safe as drinking water. However, it is also important to investigate other potential water contaminations such as chemicals and microbial and radiological materials for a longer period of time, including human body fluids, in order to assess the overall water quality of Perak state

The Periosteal Bone Surface is Less Mechano-Responsive than the Endocortical

Dynamic processes modify bone micro-structure to adapt to external loading and avoid mechanical failure. Age-related cortical bone loss is thought to occur because of increased endocortical resorption and reduced periosteal formation. Differences in the (re)modeling response to loading on both surfaces, however, are poorly understood. Combining in-vivo tibial loading, in-vivo micro- tomography and finite element analysis, remodeling in C57Bl/6J mice of three ages (10, 26, 78 week old) was analyzed to identify differences in mechano- responsiveness and its age-related change on the two cortical surfaces. Mechanical stimulation enhanced endocortical and periosteal formation and reduced endocortical resorption; a reduction in periosteal resorption was hardly possible since it was low, even without additional loading. Endocortically a greater mechano-responsiveness was identified, evident by a larger bone-forming surface and enhanced thickness of formed bone packets, which was not detected periosteally. Endocortical mechano-responsiveness was better conserved with age, since here adaptive response declined continuously with aging, whereas periosteally the main decay in formation response occurred already before adulthood. Higher endocortical mechano-responsiveness is not due to higher endocortical strains. Although it is clear structural adaptation varies between different bones in the skeleton, this study demonstrates that adaptation varies even at different sites within the same bone

Leaf spot on lettuce (Lactuca sativa) caused by Stemphylium solani, a new disease in Malaysia.

In June 2011, lettuce (Lactuca sativa) plants cultivated in major lettuce growing areas in Malaysia, including the Pahang and Johor states, had extensive leaf spots. In severe cases, disease incidence was recorded to be more than 80%. Symptoms on 50 plants were initially water-soaked spots (1-2 mm in diameter) on leaves, which then became circular spots spreading over much of the leaves. Main lettuce growing areas infected by the pathogen in the aforementioned states were investigated and the pathogen was isolated onto potato dextrose agar. Fourteen isolates were identified as Stemphylium solani based on morphological criteria. To confirm morphological characterization, the DNA of the fungus was extracted from mycelium and PCR was conducted using universal primers ITS5 (5′-GGAAGTAAAAGTCGTAACAAGG-3′) and ITS4 (5′-TCCTCCGCTTATTGATATGC-3′), which amplified the internal transcribed spacer (ITS) region of rDNA. The sequencing result was subjected to BLAST analysis, revealing a 99% similarity to other published sequences in the GenBank database (GenBank accession nos. AF203451 and HQ840713). This is thought to be the first report of Stemphylium solani on lettuce in Malaysia

Meson Thermalization in Various Dimensions

In gauge/gravity duality framework the thermalization of mesons in strongly coupled (p+1)-dimensional gauge theories is studied for a general Dp-Dq system, q>=p, using the flavour Dq-brane as a probe. Thermalization corresponds to the horizon formation on the flavour Dq-brane. We calculate the thermalization time-scale due to a time-dependent change in the baryon number chemical potential, baryon injection in the field theory. We observe that for such a general system it has a universal behaviour depending only on the t'Hooft coupling constant and the two parameters which describe how we inject baryons into the system. We show that this universal behaviour is independent of the details of the theory whether it is conformal and/or supersymmetric.Comment: 26 pages, 2 figure
