in this research, first, kinematic and dynamic equations of a 4-dof 3-link robotic finger are derived using denavit-hartenberg convention and lagrange’s formulation. to model the muscles, several springs and dampers are placed between the finger links. then, two advanced controllers, namely adaptive-robust and adaptive-neural, which can control the robotic finger in presence of parametric uncer...

background: wolbachia  are common intracellular bacteria that infect different groups of arthropods including mos­quitoes. these bacteria modify host biology and may induce feminization, parthenogenesis, male killing and cyto­plasmic incompatibility (ci). recently wolbachia  is being nominated as a bio-agent and paratransgenic candidate to control mosquito borne diseases. methods: here we repor...

Abstract Background Duodenal papilla carcinoma (DPC) is a rare malignancy of the gastrointestinal tract with high recurrence rate, and pathogenesis this highly malignant neoplasm yet to be fully elucidated. This study aims identify key genes further understand biology underlying molecular alterations driving DPC, which could potential diagnostic or therapeutic targets. Methods Tumor samples thr...

Abstract Bio-based and biodegradable plastics such as mulching films are widely used in agricultural field sites. However, there limited studies of their impact on plant development health even though an important soil-borne pathogen F . solani has been reported to associate with various types bio-based plastics, especially polybutylene succinate-co-adipate (PBSA). To evaluate the influence PBS...

Lignocellulose—a major component of biomass available on earth is a renewable and abundantly available with great potential for bioconversion to value-added bio-products. The review aims at physio-chemical features of lignocellulosic biomass and composition of different lignocellulosic materials. This work is an overview about the conversion of lignocellulosic biomass into bio-energy products s...

We investigate the effect of pair creation on a shock structure. Actually, particles accelerated by a shock can be sufficiently energetic to boost, via Inverse Compton (IC) process for example, surrounding soft photons above the rest mass electron energy and thus to trigger the pair creation process. The increase of the associated pair pressure is thus able to disrupt the plasma flow and possib...

Keeping in view, the challenges concerning agro-ecosystem and environment, the recent developments in biotechnology offers a more reliable approach to address the food security for future generations and also resolve the complex environmental problems. Several unique features of cyanobacteria such as oxygenic photosynthesis, high biomass yield, growth on non-arable lands and a wide variety of w...

Resorcinol-formaldehyde (RF) resin is a kind of excellent exterior-grade wood structural adhesive, which can be conveniently cold-set for various applications. In order to decrease the production cost, pyrolysis bio-oil from renewable bioresources was used to replace resorcinol to synthesize the bio-oil-resorcinol-aldehyde (BRF) resin. The effect of replacing resorcinol with bio-oil on the prop...

Anorganic bovine bone matrix (Bio-Oss®) has been used for a long time for bone graft regeneration, but has poor osteoinductive capability. The use of recombinant human bone morphogenetic protein-2 (rhBMP-2) has been suggested to overcome this limitation of Bio-Oss®. In the present study, heparin-mediated rhBMP-2 was combined with Bio-Oss® in animal experiments to investigate bone formation perf...
