We study the astrophysical reaction rate for the formation of Be through the three body reaction α(αn, γ). This reaction is one of the key reactions which could bridge the mass gap at A = 8 nuclear systems to produce intermediate-to-heavy mass elements in alphaand neutron-rich environments such as r-process nucleosynthesis in supernova explosions, s-process nucleosynthesis in asymptotic giant b...

Native aspen (Populus tremuloides) was pretreated using sulfuric acid and sodium bisulfite (SPORL) and dilute sulfuric acid alone (DA). Simultaneous enzymatic saccharification and fermentation (SSF) was conducted at 18% solids using commercial enzymes with cellulase loadings ranging from 6 to 15 FPU/g glucan and Saccharomyces cerevisiae Y5. Compared with DA pretreatment, the SPORL pretreatment ...

The functional interaction of outer membrane proteins of E. coli can be studied using phage and colicin receptors which are essential components of penetration systems. The uptake of ferric iron in the form of the ferrichrome complex requires the ton A and ton B functions in the outer membrane of E. coli. The ton A gene product is the receptor protein for phage T5 and is required together with ...

a 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. plain x-ray revealed a large cauliflower shaped exophytic mass at the level of t8, t9 and t10 vertebrae. computed tomography (ct) and magnetic resonance imaging (mri) showed an abnormal bony mass arising from the posterior arch of t9 with protrusion...

We have investigated the effect of age on thoracic extradural dose requirements in 62 patients aged 20-79 yr. Fifteen millilitre of 2% mepivacaine was administered at a constant rate (1 ml s-1) by syringe pump through an extradural needle at the T9-10 interspace. A mean of 15.5 (SD 4.2) spinal segments were blocked 15 min after completion of the administration. The extradural dose requirement d...

Multiple myeloma is a fatal hematological malignancy, with the most common localization being the spine. A 72-year-old male patient presented with progressive back pain and dysfunction of ambulation. Spinal computed tomography (CT) and magnetic resonance imaging (MRI) showed spinal cord compression at the T9-T10 level due to an extensive epidural mass in the spinal canal, a large lytic mass of ...

Prosedur kerja dilakukan dalam adalah sebagai berikut : (1) Pengupasan Testa Kakao, (2) Pengeringan Pengpresan Nib Kakao dengan perlakuan 3 lapis nib kakao, 5 7 (3) Analisa Kadar Lemak/minyak,...

A 52-year-old man came to hospital with the chief complaint of backache for 4 months. The patient had had diabetes mellitus for 9 years. He had frequently traveled to northeastern Thailand. Four months prior to admission, he suffered from backache. The pain progressively increased in 2 months before admission with fever, weakness of both legs and difficult walking and urine voiding. Physical ex...
