The toxicological and biochemical characteristics of acetylcholinesterases (AChE) in nine populations of the common pistachio psyllid, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), were investigated in Kerman Province, Iran. Nine A. pistaciae populations were collected from pistachio orchards, Pistacia vera L. (Sapindales: Anacardiaceae), located in Rafsanjan, Anar, Bam, ...

The early Cambrian Takab iron ore deposit is situated in the northern part of Sanandaj-Sirjan zone, western Iran. It consists banded, nodular and disseminated magnetite hosted folded micaschists. Trace element Fe O isotopic experiments reveal various hydrothermal precipitation environments under reduced to slightly oxidizing conditions. Disseminated has high Ti (945–1940 ppm) positively correla...

The paper is devoted to the accuracy improvement of robot-based milling by using an enhanced manipulator model that takes into account both geometric and elastostatic factors. Particular attention is paid to the model parameters identification accuracy. In contrast to other works, the proposed approach takes into account impact of the gravity compensator and link weights on the manipulator elas...

Africa should industrialize. Without structural change it cannot sustain recent growth. Economies with more diverse and sophisticated industrial sectors tend to grow faster. But since 1980 Africa has deindustrialized. The paper shows that between 1975 and 2005 the size, diversity and sophistication of industry in Africa have all declined. An industrialization strategy containing two elements is...
