Soil concentrations and degradation rates of methyl isothio-cyanate (MITC), chloropicrin (CP), 1,3-dichloropropene (1,3-D), and dimethyl disulfide (DMDS) were determined under fumigant application scenarios representative of commercial raised bed, plastic mulched vegetable production systems. Five days after application, 1,3-D, MITC, and CP were detected at concentrations up to 3.52, 0.72, and ...

Highlights The largest contributors to odor activity values (OAV) were heptanoic acid (23.5%), hexanoic (17.6%), indole (14.7%), and dimethyl disulfide (DMDS) (9.50%). Measurements of volatile organic compounds (VOC) greater from plots where manure was surface-applied than with incorporated manure. Emissions DMDS trisulfide (DMTS) (0.318 0.074 µg m -2 min -1 , respectively) for beef cattle fed ...

BACKGROUND The adherence to treatment with injectable disease-modifying drugs (DMDs) in multiple sclerosis (MS) may benefit from adequate information provision and management of expectations. The communication between patients and physicians is very important in this respect. The current study investigated the perspectives and experiences of the MS patients and neurologists concerning the choic...

in this research, zeolite a was synthesized from waste porcelain and cds nano-particles were doped in zeolite framework by a precipitation after an ion exchanging process. all raw and modified samples were characterized by ft-ir, xrd and sem methods. primary experiments showed that the good efficiency of loaded nano cds onto the zeolite a for photodecomposition of dimethyldisulfide (dmds) under...

Purpose The collaboration of conventional western medicine (CWM) with traditional Korean medicine (TKM) is a critical issue in the Korean medical system. Becoming dual medical license holders (DMD) having both MD and TKMD licenses is considered a way of overcoming conflicts arising from mutual ignorance and misunderstanding. This study aims to investigate medical practices and attitudes of DMDs...

In order to put the present model and our results into the right perspectives we describe first key steps in multiuser source coding theory. We are given a discrete memoryless double source (DMDS) with alphabets X , Y, and generic variables X , Y , i.e., a sequence of independent replicas (Xt, Yt), t = 1, 2, . . . of the pair of random variables (X,Y ) taking values in the finite sets X and Y, ...

BACKGROUND: Magnetic resonance imaging (MRI) is indispensable for diagnosing neurological conditions such as multiple sclerosis (MS). MRI also supports decisions regarding the choice of disease-modifying drugs (DMDs). Determining in vivo tissue concentrations DMDs has potential to become an essential clinical tool therapeutic drug monitoring (TDM). The aim here was examine feasibility fluorine-...

Introduction Polysulfides play a critical role in the optimization of many chemical processes. Dimethyl disulfide (DMDS), for example, is used as coke inhibiting additive in steam cracking furnaces and can also be used as photolytic initiator during free radical polymerization.[1, 2] Also tetrasulfides are frequently used in chemistry, mostly as inhibitors during polymerization reactions. Despi...
