Abstract Numerous studies have been reported to ascertain the benefits of starter fertilization for corn ( Zea mays L.) production, but most rely on data collected by measuring early growth or grain yield at harvest. As a more conclusive evaluation, five field trials were conducted using 15 N‐labeled urea‐ammonium nitrate (UAN) solution (90 kg N ha −1 ) compare single and dual subsurface band p...

In the title molecular salt, C(10)H(15)NH(3) (+)·C(7)H(5)O(2) (-), both carboxyl O atoms act as acceptors for strong N-H⋯O inter-molecular hydrogen-bond inter-actions with the ammonium group in the cation, generating infinite chains along the b axis. A weak C-H⋯π inter-action is also present.

In this communication, we demonstrate our recent finding that iron-substituted SBA-15 (Fe-SBA-15) microparticles possess intrinsic peroxidase-like activity and can catalyze the oxidation of peroxidase substrate 3,3',5,5'-tetramethylbenzidine (TMB) by H(2)O(2) to develop a blue color in aqueous solution, leading to a simple approach towards colorimetric detection of H(2)O(2) with a linear detect...

Background and purpose: Equity in access to health care has become a desirable policy objective. Therefore, accessibility to health care should be provided based on health needs rather than socio- demographic variables. This will lead to a better utilization of health care and improvement of equity in health. The aim of this paper is to examine the effects of family socio-economic status as an ...

A new method for the preparation of well-defined functionalized mesoporous SBA-15 has been developed by a one-step co-condensation method using trimethallylsilanes as organosilane sources. This new method enables the incorporation of various bulky organic functional groups with long alkyl chain tethers into the mesoporous silica network.
