A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

open access: yesMacromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

PRESENCE OF hemA-LIKE AND hemT-LlKE GENES IN A JSUMBER OF ANOXYGENIC PHOTOSYNTHETIC BACTERIAL ISOLATES FROM INDONESIA AND SOIL SAMPLES FROM BOGOR AREA

open access: yesBiotropia: The Southeast Asian Journal of Tropical Biology, 2011
The Rhodobacter sphaeroides hemA and hemT are known to encode a distinct 5-aminolevulinic acid (ALA)-synthase isozyme. This enzyme catalyzes the first and rate limiting step in ALA biosynthesis through the C4 pathway.

Bushmeat consumption frequency and preferences among rural households in a West African savanna landscape: Implications for food security and conservation

open access: yesPeople and Nature, EarlyView.
Abstract The drivers of consumer demand for bushmeat are relatively well studied in tropical forest systems, but much less so in savanna areas. This is important because differing ecological and socio‐economic conditions lead to different factors affecting the relationship between local communities and their natural resources.

HEMA in the map of science

open access: yesActa Periodica Duellatorum, 2013
This article aims to place HEMA on the map of science. To be able to start this work I have to find an appropriate definition on science and on discipline (field of science). After describing main characters of a discipline I investigate HEMA if it shows

Axillary Lymph Node Yield Following Axillary Dissection in Biopsy‐Proven Node‐Positive Breast Cancer: Neoadjuvant Systemic Therapy Versus Primary Surgery

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Background Neoadjuvant systemic therapy (NAST) induces morphological changes within the axilla; however, its impact on lymph node yield (LNY) following axillary lymph node dissection (ALND) is less clear. Methods A retrospective cohort study was performed including female patients who underwent ALND for biopsy‐proven node‐positive breast ...
