Solar photovoltaics,based upon silicon,are the most popular form of solar cell with efficiencies around 20%.These efficiencies can be further increased by employing light trapping schemes to minimise optical losses through scattering and reflection which enhances the amount of light absorbed and number of photo-carriers *** approaches employ antireflection coatings（ARCs） or texturise the surface of the silicon disks,so that the structure consists of an array of needles which can absorb most of the ***,these structures are created by leaching the silicon with hydrofluoric-based acids or by reactive ion etching（RIE） *** paper reviews some of the methods for improving the energy efficiency of silicon production,and describes the use of electro-deoxidation of SiO;layers,on silicon,in molten calcium chloride to form nanoporous black silicon（b-Si） *** coating b-Si surface with TiO;,a common ARC,extremely black surfaces with negligible reflectance of about 0.1%,are produced,which can have applications for low-cost high efficiency solar cells.

A rapid and sensitive liquid chromatography-tandem mass spectrometry（LC-MS/MS） method for the de- termination of cefotetan in human plasma was developed and validated. After the protein precipitation of sample with acetonitrile, the analyte and internal standard（IS）, tramadol, were separated on a Zorbax XDB C8 column using ace- tonitrile/1%（volume fraction） formic acid（volume ratio 35：65, pH=2.5） as mobile phase at a flow rate of 1.0 mL/min with a 1 ： 1 split. The detection was performed by electrospray ionization with positive ion mode, followed by multiple reaction monitoring of the transitions for cefotetan at m/z 576.3→460.2（quantifier） and m/z 576.3→432.2（qualifier） and for IS at m/z 264.1→58.1. Cefotetan and IS were eluted at 1.86 and 1.87 rain, respectively. The assay was linear over the concentration range of 0.1-100 gg/mL for 20 μL of human plasma only with intra- and inter-day preci- sions（expressed as the relative standard deviation） of less than 6.62% and accuracies（as relative error） of ＋1.31%. The method was applied to the pharmacokinetic study of a l-h intravenous infusion of 1.0 g of cefotetan disodium for human volunteers（n=6）.

During calcining the aluminum hydroxide according to the Bayer process in a rotary kiln,the process of incomplete conversion to alpha alumina by soft calcination leads to a special intermediate alumina product containing microcrystalline of primary crystal alpha alumina particles less than 0.4μm,and other alumina phases with finer microcrystalline of less than 0.2μm *** special alumina powder has similar properties to silica fume or clay,such as high surface area and reactivity,fast wetting,low water demand and high *** can partially or completely replace silica fume and clay in dry gunning *** works towards improving the high temperature resistance of the gunning material matrix as well as the corrosion resistance and service life of the gunning *** application results show that:the ladle cementfree alumina-magnesia dry gunning mix with this special alumina sub-micro powder,compared with traditional dry gunning materials,has lower rebound loss(<10%),better adhesion rate,higher corrosion resistance and peeling resistance;and it can replace the veneering casting repair to achieve the similar performance.A further improvement goal is to replace the initial casting linings,thus this concept will give a new revolution to the monolithic steel ladles.

We describe an innovative technique of ultrasound-guided greater occipital nerve (GON) hydrodissection for treatment of cervicogenic headache and occipital neuralgia. A 35-year-old female presented to the pain clinic with severe chronic cervicogenic headache impacting her sleep, work and activities of daily living. Conservative management had failed to adequately resolve her pain. Ultrasound-guided suboccipital hydrodissection of the greater occipital nerve was performed with the patient in the prone position. After skin sterilization, the linear ultrasound transducer was oriented in a transverse orientation at the level of the C2-C3 vertebrae. The needle was advanced from medial to lateral “in-plane” under direct ultrasound visualization, until the needle was positioned at the C2 lamina. After confirming the needle tip position, 10 ml of hydrodissection fluid was inj.cted with good visualization of distribution of the solution. The patient described immediate and significant improvement in her symptoms. She reported a sustained decrease in pain scores when followed up in the pain clinic at six and twelve weeks respectively. To the best of our knowledge this is the first application of ultrasound-guided hydrodissection of the GON for cervicogenic headache. It offers a novel, safe and effective technique to aid in the diagnosis and treatment of a common pain condition.

Constitutive Activation of NF-κB in Pancreatic Cancer:The Mechanism, Function, and Therapeutic Target

1st British-Sino j.int Symposium on Chemistry CCS/RSC/EPSRC Workshop on Materials Chemistry

作者： paul j. Low Department of Chemistry Durham University

＜正＞Bimetallic complexes [{MLn}（μ-bridge）{MLn}], in which two metal sites are linked by some conj.gated bridging ligand, promote interest both as fundamental research obj.cts with which to probe intramolecular electron-transfer reactions and as potential functional units within molecular-scale electronic devices. This presentation give an overview of the linear conj.gated ligand systems of particular interest to the Durham group, including diethynyl-para-carboranes, diethynyl aromatics and the novel "cyanide-like" species C≡CC≡N, and highlight the experimental and computational methods used to probe the underlying electronic structures of these compounds.

Is analysis of lower esophageal sphincter vector volumes of value in diagnosing gastroesophageal reflux disease?

第四届中国肿瘤学术大会暨第五届海峡两岸肿瘤学术会议

＜正＞Pancreatic adenocarcinoma is the fourth leading cause of adult cancer mortality in the United States. The five -year survival rate continues at 1-3% and the median survival after diagnosis is often less than 6 months. Pancreatic-cancer is characterized by poor prognosis and lack of response to conventional therapy. Hence, pancreatic cancer poses one of the greatest challenges incancer research. Only through basic and translational research aimed at understanding

AIM:With successful surgical treatment of gastroesophageal reflux disease(GERD),there is interest in understanding the anti-reflux barrier and its mechanisms of *** date, the potential use of vector volumes to predict the DeMeester score has not been adequately explored. METHODS:627 patients in the referral database received esophageal manometry and ambulatory 24-hour pH *** data included LES resting pressure(LESP), overall LES length(OL)and abdominal length(AL),total vector volume(TVV)and intrabdominal vector volume(IVV). RESULTS:In cases where LESP,TVV or IVV were all below normal,there was an 81.4%probability of a positive DeMeester *** cases where all three were normal, there was an 86.9%probability that the DeMeester score would be ***-operating characteristics(ROC) for LESP,TVV and IVV were nearly identical and indicated no useful cut-off *** regression demonstrated that LESP and IVV had the strongest association with a positive DeMeester score;however,the regression formula was only 76.1%accurate. CONCLUSION:While the indices based on TVV,IVV and LESP are more sensitive and specific,respectively,than any single measurement,the measurement of vector volumes does not add significantly to the diagnosis of GERD.

THE T6P-SnRK1 SIGNALING PATHWAY IN PLANTS,The biosynthetic route for the synthesis of trehalose in plants is through a low-flux pathway that leads to the accumulation of micromolar amounts of trehalose 6-phosphate(T6P)and trehalose when sucrose is available.T6P accumulates in proportion to sucrose(Lunn et al.,2006)as an indispensable regulator of carbohydrate utilization(Schluepmann et al.,2003).At least some of the indispensability of T6P and its profound and widespread effects on plant growth and development can be explained through T6P inhibition of the SNF1-related protein kinase SnRK1(Zhang et al.,2009),a central regulator of plant responses to carbon and energy status.
