Optical properties, durability, and system aspects of a new aluminium-polymer-laminated steel reflector for solar concentrators
A newly developed aluminium-polymer-laminated steel reflector for use in solar concentrators was evaluated with respect to its optical properties, durability, and reflector performance in solar thermal and photovoltaic systems. The optical properties of the reflector material were investigated using spectrophotometer and scatterometry. The durability of the reflector was tested in a climatic test
Amplification of 12q13 and 12q15 sequences in a sclerosing epithelioid fibrosarcoma
Sclerosing epithelioid fibrosarcoma (SEF) is a recently described entity. It is a low-grade sarcoma that occurs primarily in the deep soft tissues of the extremities of adults. It may histologically simulate benign lesions such as fibroma and myxoma or malignancies such as sclerosing carcinoma and lymphoma, extraskeletal myxoid chondrosarcoma, clear cell sarcoma of tendons and aponeuroses, and syn

A comparison of the Gauss-Newton and quasi-Newton methods in resistivity imaging inversion
The smoothness-constrained least-squares method is widely used for two-dimensional (2D) and three-dimensional (3D) inversion of apparent resistivity data sets. The Gauss-Newton method that recalculates the Jacobian matrix of partial derivatives for all iterations is commonly used to solve the least-squares equation. The quasi-Newton method has also been used to reduce the computer time. In this me
The effects of a pesticide mixture on aquatic ecosystems differing in trophic status: responses of the macrophyte Myriophyllum spicatum and the periphytic algal community
The effects of a pesticide mixture (asulam, fluazinam, lambda-cyhalothrin, and metamitron) on aquatic ecosystems were investigated in 20 outdoor aquatic microcosms. Ten of the microcosms simulated mesotrophic aquatic ecosystems dominated by submerged macrophytes (Elodea). The others simulated eutrophic ecosystems with a high Lemna surface coverage (Lemna). This paper describes the fate of the chem

The Bhagavadgītā Path of Yoga
On the basis of text-internal evidence, the article supports the view that the soteriological doctrines of the Bhagavadgītā comprise a structured and progressive system in which partially conflicting elements derived from contemporary religious teachings have been deliberately arranged in hierarchical form, and touches on philological problems in connection with particular passages.

Artificial Life Techniques for Load Balancing in Computational Grids
Load balancing is a very important and complex problem in computational grids. A computational grid differs from traditional high performance computing systems in the heterogeneity of the computing nodes and communication links, as well as background workloads that may be present in the computing nodes. There is a need to develop algorithms that could capture this complexity yet can be easily impl
Approximating the maximum clique minor and some subgraph homeomorphism problems.
We consider the “minor” and “homeomorphic” analogues of the maximum clique problem, i.e., the problems of determining the largest h such that the input graph (on n vertices) has a minor isomorphic to Kh or a subgraph homeomorphic to Kh, respectively, as well as the problem of finding the corresponding subgraphs. We term them as the maximum clique minor problem and the maximum homeomorphic clique p

Characterisation of a plasma membrane-associated phospholipase A(2) activity increased in response to cold acclimation
We here demonstrate the presence of a plasma membrane-associated phospholipase A(2) (EC 3.1.1.4; PLA(2)) activity in spinach (Spinacia oleracea) leaves. The pH profile of the spinach plasma membrane PLA(2) activity revealed two peaks, one at pH 4.4 and one at pH 5.5. The activity at pH 5.5 had an absolute requirement of Ca2+, with full enzyme activity at 10mumol/L Ca2+. The Ca2+-dependent PLA(2) a
p-Benzoquinone in aqueous solution: Stark shifts in spectra, asymmetry in solvent structure
Results from a simulation of p-benzoquinone (PBQ) in water is presented. An explicit solvent representation is used together with a multiconfigurational ab initio quantum chemical method. The electronic n -> pi* transitions are studied in aqueous solution and the two such transitions are both blue-shifted but to different degree. Both non-equilibrium and many-body effects are found to have decisiv
Silent seizures in sick infants in early life. Diagnosis by continuous cerebral function monitoring
Cerebral electric activity was surveilled with a Cerebral Function Monitor (CFM) technique in 87 newborn infants under neonatal intensive care. A total of 26 infants had electrographical signs of repeated seizure activity. Among these infants 14 had periods of one hour or more of silent seizures activity. Among these infants 14 had periods of one hour or more of silent seizures, i.e. typical patte
Protein kinase C inhibition attenuates vascular ETB receptor upregulation and decreases brain damage after cerebral ischemia in rat.
Background: Protein kinase C (PKC) is known to be involved in the pathophysiology of experimental cerebral ischemia. We have previously shown that after transient middle cerebral artery occlusion, there is an upregulation of endothelin receptors in the ipsilateral middle cerebral artery. The present study aimed to examine the effect of the PKC inhibitor Ro-32-0432 on endothelin receptor upregulati
Characterization of epitope structure for 53 monoclonal antibodies against prostate-specific antigen
Prostate-specific antigen (PSA) is the most widely used marker of prostate cancer. Assays for PSA are based on anti-PSA antibodies, and the characterization and selection of these antibodies is important for determining their optimum performance. In our study, we characterized the reactivity of 53 antibodies, submitted to the ISOBM TD-3 PSA Workshop, using free PSA, PSA complexed to alpha1-antichy
Clinical Predictors for Death in HIV-positive and HIV-negative Tuberculosis Patients in Guinea-Bissau.
To assess easily monitored predictors for tuberculosis mortality. Risk factors for tuberculosis mortality were assessed during the 8-month treatment in 440 men and 269 women diagnosed with confirmed or presumed intrathoracic tuberculosis included prospectively in Guinea-Bissau from May 1996 to April 2001. A civil war occurred in the study area from June 1998 to May 1999. 12% were HIV-1 positive, 1
