Prediction of Citizens' Decisions on Transport Mode Choice in Bandung City, Indonesia by Using General Linear Model Given Existing Level of Pedestrian Friendly Environment

Significant contribution of non-motorized transport to energy and environment has changed the view of people on walking or cycling as one of transport modes. While promoting mass rapid transport, modern cities tend to promote pedestrianization as well to encourage people to walk instead of relying on motorized transport. Creating pedestrian friendly environment in particular parts of the city, especially in CBD, is one such attempt. This study tries to investigate the correlation between perceptions of the citizens on pedestrian friendly environment (PFE) and their decision on the choices of transport modes. The central business district of Bandung City in Indonesia was chosen as the study area. A questionnaire-based research was used to acquire data on citizens' perception. Eight variables were employed to understand citizens' perception on PFE. The result shows that PFE does influence citizens' decision on their transport modes choice

Fruit morphological characteristics of cultivated Aquilaria lam. (Thymelaeaceae) in Peninsular Malaysia

The agarwood-producing tree, Aquilaria spp. was recently domesticated and largely cultivated for the purpose of sustainably producing agarwood in Malaysia. In this study, fruit morphological characteristics of five Aquilaria species commonly cultivated in Peninsular Malaysia are reported. Each species has significant fruit or capsule characteristics that could be used in speciesidentification: Aquilaria crassna - huge and wrinkled, Aquilaria hirta - velvety and obtuse calyx lobes, Aquilaria malaccensis - paper-like texture and triangular calyx lobes, Aquilaria sinensis - diamond-shaped and oblong calyx lobes, and Aquilaria subintegra - fine hairs and rounded calyx lobes. These features are significant taxonomic characteristics for differentiating the five species

Hierarchical multiple regression modelling on predictors of neighbourhood satisfaction in violence-induced segregated urban environments

Violence-induced segregated urban environments (VISUE) are quite unique urban centres for their characteristic of neighbourhood sharing among residents before the resultant parting triggered by violence. Yet, not much is known about the neighbourhood satisfaction of inhabitants in this type of urban setting. Such knowledge can provide hints on the factors to be prioritized in planning for improvement of neighbourhood satisfaction of residents in these cities. This paper thus examines the key predictors of neighbourhood satisfaction in a VI-SUE. Household heads (n = 289), cutting across the three identifiable types of neighbourhoods in Jos, Nigeria, expressed their level of satisfaction on a 71-item self-administered structured survey instrument. The principal component analysis with varimax rotation option explored 10 factors to represent the examined attributes of the neighbourhood environment. The third (final) in the sequence of hierarchical regression models estimated, indicates that none of the socio-economic and demographic attributes and dwelling attributes is significant in pre-dicting neighbourhood satisfaction in VISUE. Three factors: neighbourhood safety and stability, social relationships, and neighbourhood facilities and services, emerge as the key predictors of neighbourhood satisfaction. On the basis of these findings, these three attributes are required to be given precedence in any policy action aiming to improve residents’ satisfaction with their neighbourhoods in VI-SUE

Photocatalytic Degradation of Methylene Blue under UV Light Irradiation on Prepared Carbonaceous TiO

This study involves the investigation of altering the photocatalytic activity of TiO2 using composite materials. Three different forms of modified TiO2, namely, TiO2/activated carbon (AC), TiO2/carbon (C), and TiO2/PANi, were compared. The TiO2/carbon composite was obtained by pyrolysis of TiO2/PANi prepared by in situ polymerization method, while the TiO2/activated carbon (TiO2/AC) was obtained after treating TiO2/carbon with 1.0 M KOH solution, followed by calcination at a temperature of 450°C. X-ray powder diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FTIR), thermogravimetric analysis (TG-DTA), Brunauer-Emmet-Teller (BET), and UV-Vis spectroscopy were used to characterize and evaluate the prepared samples. The specific surface area was determined to be in the following order: TiO2/AC > TiO2/C > TiO2/PANi > TiO2 (179 > 134 > 54 > 9 m2 g−1). The evaluation of photocatalytic performance for the degradation of methylene blue under UV light irradiation was also of the same order, with 98 > 84.7 > 69% conversion rate, which is likely to be attributed to the porosity and synergistic effect in the prepared samples

Trypanosoma brucei aquaglyceroporin 2 is a high-affinity transporter for pentamidine and melaminophenyl arsenic drugs and the main genetic determinant of resistance to these drugs.

OBJECTIVES: Trypanosoma brucei drug transporters include the TbAT1/P2 aminopurine transporter and the high-affinity pentamidine transporter (HAPT1), but the genetic identity of HAPT1 is unknown. We recently reported that loss of T. brucei aquaglyceroporin 2 (TbAQP2) caused melarsoprol/pentamidine cross-resistance (MPXR) in these parasites and the current study aims to delineate the mechanism by which this occurs. METHODS: The TbAQP2 loci of isogenic pairs of drug-susceptible and MPXR strains of T. brucei subspecies were sequenced. Drug susceptibility profiles of trypanosome strains were correlated with expression of mutated TbAQP2 alleles. Pentamidine transport was studied in T. brucei subspecies expressing TbAQP2 variants. RESULTS: All MPXR strains examined contained TbAQP2 deletions or rearrangements, regardless of whether the strains were originally adapted in vitro or in vivo to arsenicals or to pentamidine. The MPXR strains and AQP2 knockout strains had lost HAPT1 activity. Reintroduction of TbAQP2 in MPXR trypanosomes restored susceptibility to the drugs and reinstated HAPT1 activity, but did not change the activity of TbAT1/P2. Expression of TbAQP2 sensitized Leishmania mexicana promastigotes 40-fold to pentamidine and >1000-fold to melaminophenyl arsenicals and induced a high-affinity pentamidine transport activity indistinguishable from HAPT1 by Km and inhibitor profile. Grafting the TbAQP2 selectivity filter amino acid residues onto a chimeric allele of AQP2 and AQP3 partly restored susceptibility to pentamidine and an arsenical. CONCLUSIONS: TbAQP2 mediates high-affinity uptake of pentamidine and melaminophenyl arsenicals in trypanosomes and TbAQP2 encodes the previously reported HAPT1 activity. This finding establishes TbAQP2 as an important drug transporter

Long-term trends of temperature, salinity, density and transient tracers in the Central Greenland Sea

We present long-term observations of temperature, salinity, tritium/3He, chlorofluorocarbon-11 (CFC 11), and chlorofluorocarbon-12 (CFC 12) for the central Greenland Gyre. The time series span the periods between 1952 and 1994 (temperature), 1981 and 1994 (salinity), 1972 and 1994 (tritium/3He), and 1982 and 1994 (CFCs). The correlation between hydrographic and transient tracer data indicates that low temperatures in the deep water in the early 1950s and between 1960 and 1980 reflect periods of higher deep water formation rates whereas periods of increasing temperatures in the late 1950s and between 1980 and 1994 are related to low deep water formation rates. However, the transient tracer observations obtained in the 1980s and early 1990s indicate that even during periods of low deep water formation, some water from the upper water column contributed to deep water formation between 1980 and 1994. In 1994, the deep water reached temperatures and salinities of −1.149 °C and 34.899, respectively, and no longer fits most of the classical definitions of Greenland Sea Deep Water (−1.29°C< Θ < −1.0°C, 34.88<S<34.90). The temperature increase in the water column between 200 and 2000 m depth between 1980 and 1994 corresponds to an average heating rate of about 5 Wm−2 over this period, resulting in a decrease in density. The 13-year warming could be balanced by intensive cooling in two winters. The surface salinity steadily increased from 34.50 in 1991 to 34.85 in 1994
