Destruction in Niger

Asparaginase from Aspergillus Niger Expressed in A. Niger

Asparaginase is an enzyme that catalyses the hydrolysis of the amino acid L-asparagine to Laspartic acid and ammonia. The asparaginase enzyme described in the DSM’s dossier is intended for use as a processing aid to reduce in food the levels of free L-asparagine, which is a major precursor in the formation of the food contaminant acrylamide. Acrylamide is formed from Lasparagine and reducing su...

Rat Destruction in Kamptee

Bone destruction in arthritis.

Rheumatoid arthritis (RA) is characterised by the presence of an inflammatory synovitis accompanied by destruction of joint cartilage and bone. Destruction of cartilage matrix results predominantly from the action of connective tissue proteinases released by RA synovial tissues, chondrocytes, and pannus tissue. Several lines of evidence in RA and in animal models of arthritis support a role for...

Creative Destruction in Industries∗

Industries where prices decline rapidly experience early ‘shakeouts’. Existing models of the shakeout do not explain this negative relation between price decline and time to shakeout. We set up a vintage-capital model that explains this relation, and we provide some evidence in support of the mechanism that we propose. The relation emerges naturally in a vintage-capital model in which shakeouts...

Modeling environmental factors on vegetation destruction in protected areas

Over the past two decades, degradation damage has increased in natural ecosystems. This research focuses solely on the degradation of soil and vegetation cover in Sorkheh Eshpar National Park. For this purpose, some physical properties of the soil (specific gravity and true porosity, moisture content, a percentage of pebbles, acidity and conductivity and soil texture) were measured. Also, the d...
