effect of partial natural rubber replaced with synthetic rubbers, styrene butadiene and cis butadiene, on failure and strength properties of bias tread nr/br based compound was studied by efficient and conventional sulfur curing systems and mixtures of different carbon black grades. it was observed that failure behavior comprising tear resistance and crack growth in substituted compounds droppe...

The calculation of carbon emissions is important to determine the footprint and environmental impact manufacturing processes assess which steps could be further optimized make greener more sustainable. A previously published holistic approach was applied in conventional laser-based material removal most intensive one. were calculated results show that drilling than drilling, while reverse true ...

We have studied the repair of X-ray-induced, potentially lethal damage (PLD) in 9 human tumour lines derived from tumours of varying radiocurability. Cells derived from 3 tumours considered non-radiocurable (1 osteosarcoma, 2 melanoma) repaired significantly more X-ray PLD than cells from 3 tumours considered radiocurable (2 breast, 1 neuroblastoma). The remaining tumour lines were intermediate...

A brain-to-brain interface (BTBI) enabled a real-time transfer of behaviorally meaningful sensorimotor information between the brains of two rats. In this BTBI, an "encoder" rat performed sensorimotor tasks that required it to select from two choices of tactile or visual stimuli. While the encoder rat performed the task, samples of its cortical activity were transmitted to matching cortical are...

We trained two monkeys to perform a fixation task. Intracortical microstimulation (ICMS) was applied to the monkey frontal eye field (FEF) while monkeys were fixating on one of five fixation LEDs. The ICMS was applied in two different manners. Under the single stimulation condition, ICMS was delivered to either right or left FEF. Under the paired stimulation condition, bilateral FEF were succes...

This Engineer Technical Letter (ETL) discusses the special problem areas and concerns related to RCC construction in order to assure that the concrete properties required are ultimately realized in the completed structure. A quality RCC product requires a coordinated effort between the structural designer, the materials engineer, the materials laboratory, and those responsible for field quality...

Kunming Hospital of National Defence 650032 [Abstract] One hundred and thirteen soft tissue ulcers, scattered in fingers and toes, caused by injection of addictive drugs in 36 patients from the Institute for Abstinence (Dali, Yunnan Province) were treated in our hospital from March 1996. They were divided into two groups. Patients in group A were treated with MEBO, while those in group B were t...

Hydatid disease has a wide geographic distribution around the world. In human, the lungs are the second most commonly affected sites. Pulmonary hydatidosis is much more frequently encountered in children than in adults. Surgical treatment has remained the standard option in the management of hydatid disease. However, surgeons were able to replicate the principles of conventional surgery using m...
