Kinetic studies have been carried out for an effective and recyclable heterogeneous Ru-HT catalyst CO 2 hydrogenation to formic acid without a base. A TON of 11 389 was successfully achieved in 24 h at 60 °C bar pressure MeOH:H O mixed solvent.

We estimated PM2.5-related public health impacts/ton emitted of primary PM2.5, SO2, and NOx for a set of power plants in the Mid-Atlantic and Lower Great Lakes regions of the United States, selected to include varying emission profiles and broad geographic representation. We then developed a regression model explaining variability in impacts per ton emitted using the population distributions ar...

BtuB is a TonB-dependent outer-membrane transporter for vitamin B12 (or cyanocobalamin, CN-Cbl) in Escherichia coli. The binding of CN-Cbl is believed to promote an unfolding or undocking of the Ton box, the conserved N-terminal energy coupling motif at the periplasmic surface of the transporter. This structural change may facilitate the interaction of BtuB with the inner membrane protein TonB....

Dinas Lingkungan Hidup dan Kebersihan Kota Bandung menargetkan pada tahun 2022 sekitar 30% timbunan sampah di Ibu Provinsi Jawa Barat bisa diolah sehingga tidak akan masuk ke tempat pemrosesan akhir. Salah satu cara menanggulanginya adalah dengan mengembangkan kawasan bebas hingga skala kelurahan. Berdasarkan data Sistem Informasi Pengelolaan Sampah Nasional (SISPSN) 2020 Kabupaten Bekasi menem...

Customized text input editors on mobile devices for languages with no standard language models, such as some African languages, are vital to allow text input tasks to be crowdsourced and thus enable quick and precise participation. We investigated 4 different mobile input techniques for complex language scripts like |Xam and collected accuracy data from experiments with the Xwerty, T9, Pinyin s...

Research was conducted by using effective management application of FYM and Azospirillum with inorganic fertilizer objective to enhance the growth yield okra crop. It has been concluded from trial that different level fertilizers in experiment gave highest value. Effective results were obtained T9 treatment combination 20 t ha-1, 2 kg ha-1 RDF 100: 60: 50 hhah ha-1. This result shown best plant...

Weathering modeling introduces blemishes such as dirt, rust, cracks and scratches to virtual scenery. In this paper we present a visual simulation technique that works well for a wide variety of weathering phenomena. Our technique, called γ-ton tracing, is based on a type of aging-inducing particles called γ-tons. Modeling a weathering effect with γ-ton tracing involves tracing a large number o...

We analyse CO2 emissions reduction costs based on project data from the Climate Cent Foundation (CCF), a climate policy instrument in Switzerland. We draw four conclusions. First, for the projects investigated, the CCF on average pays € 63/t. Due to the Kyoto Protocol, the CCF buys reductions until 2012 only. This cutoff increases reported per ton reduction costs, as the additional lifetime pro...

By analyzing the decisions of policy makers and in addition public referenda, shadow prices for global warming (ca. 5 to 22 € per ton of CO2) and exceedance of critical loads for eutrophication and acidification (ca. 100 € per hectare of exceeded area and year with a range of 60 – 350 €/ha year) have been developed. These data are complementary to the valuation steps in ExternE, and can be used...

Shallots productivity can be increased through improved cultivation by using high-quality varieties and organic fertilizers. The objective of the present study was to determine growth yields shallots with application "Kompota"; fertilizers enriched microbes (Azospirillum sp, Azotobacter Aeromonas sp). experiment carried out from April July 2020 in Panimbang Jaya village Pandeglang Regency, Bant...
