Abstract Woodchip bioreactors are capable of removing nitrate from agricultural runoff and subsurface tile drain water, alleviating human health hazards harmful discharge to the environment. Water pumped sumps nearby ditches or channels could be cost-effectively diverted through a woodchip bioreactor remove prior into local waterways. Sizing achieve targeted outlet concentrations within minimum...

Linear low-density polyethylene (LLDPE) materials may contain components, which are soluble at room temperature. These influence physical properties or raise concerns for end-users and regulatory bodies because LLDPE is widely used food packaging. Due to the nonpolar amorphous nature of temperature part LLDPE, its molecular characterization with common methods polyolefin analysis, such as Tempe...

With the rapid global expansion of road networks, asphalt industry faces several environmental challenges, such as material shortages, concerns, escalating costs, demand for eco-friendly materials, and implementation “Net Zero” policies. Given these challenges recognizing need to explore new solutions, this research evaluated binder samples incorporating Warm Mix Asphalt (WMA) Reclaimed Pavemen...

sio2-supported silyl chromate catalyst is an important industrial catalyst for production of high grade hdpepipe materials. the control of the short chain branch (scb) distribution using this catalyst system is still a greatchallenge. in this work, ethylene and 1-hexene copolymers were synthesized using sio2-supported silyl chromatecatalyst combined with triisobutylaluminium (tiba), triethylalu...

In this talk we will review the major additions and improvements made to the ROOT system in the last 18 months and present our plans for future developments. The additions and improvements range from modifications to the I/O sub-system to allow users to save and restore objects of classes that have not been instrumented by special ROOT macros, to the addition of a geometry package designed for ...

The DNA sequence of a 225.4 kilobase segment of the Escherichia coli K-12 genome is described here, from 76.0 to 81.5 minutes on the genetic map. This brings the total of contiguous sequence from the E.coli genome project to 725.1 kb (76.0 to 92.8 minutes). We found 191 putative coding genes (ORFs) of which 72 genes were previously known, and 110 of which remain unidentified despite literature ...

actly in the last delay element. In the measurement, the input period T,,, with TIl<Tref will be fed into the delay In this paper, we present a new CMOS time-toline instead. Suppose that T,, disappears in the n-th delay digital converter (TDC) with the cyclic delay line strucelement, then the width is measured as n x TrCf / N , ture. The static supply current is 2-nA only. Furthermore, where N ...

Genes for trehalose metabolism are widespread in higher plants. Insight into the physiological role of the trehalose pathway outside of resurrection plant species is lacking. To address this lack of insight, we express Escherichia coli genes for trehalose metabolism in Arabidopsis thaliana, which manipulates trehalose 6-phosphate (T6P) contents in the transgenic plants. Plants expressing otsA [...

Chromium-vanadium (Cr-V) bimetallic catalysts are prepared by the introduction of vanadium into the Phillips catalyst which is one of the most significant industrial ethylene polymerization catalysts for tuning the Phillips catalyst performances and improving polyethylene properties. In the present work, titanium species were introduced into the fluorine-modified chromium-vanadium bimetallic ca...
