Winter in Destruction

Efficacy of Cotton Root Destruction and Winter Cover Crops for Suppression of Hoplolaimus columbus.

The efficacy of rye (Secale cereale) and wheat (Triticum aestivum) winter cover crops and cotton stalk and root destruction (i.e., pulling them up) were evaluated in field tests during two growing seasons for Hoplolaimus columbus management in cotton. The effect of removing debris from the field following root destruction also was evaluated. Wheat and rye produced similar amounts of biomass, an...

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...
