This study considered effects of reduced [O-3] on wheat yield. Open-top chamber charcoal filtered air treatments were compared with non-filtered treatments for field-grown wheat. 30 experiments meeting requirements were found, representing nine countries in North America, Europe and Asia. 26 experiments reported improved yield and 4 experiments reduced yield by filtration, a significant positive e

The thermal model and simulation of vehicles components is necessary within the development phase of the vehicle production process. It is important to understand the thermal processes of high temperature components in the vehicle, such as the exhaust system. The exhaust system presents a high thermal activity that increases the temperature of the exhaust system itself and the nearby surrounding e
Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. Modern telescopes, both ground- and space-based, like the Very Large Telescope (VLT) or the James Webb Space Telescope (JWST) will drive forward the
The importance of migrants' remittance transfers in global capital flows is steadily growing. A large body of literature has been dedicated to the study of remittances, its underlying causes, and its effects on development in receiving countries. Albania, one of the poorest countries in Europe, experienced massive emigration in its post-communist transition era, and remittances have since cons
Disease gene identification is still a challenge despite modern high-throughput methods. Many diseases are very rare or lethal and thus cannot be investigated with traditional methods. Several in silico methods have been developed but they have some limitations. We introduce a new method that combines information about protein-interaction network properties and Gene Ontology terms. Genes with high
Polyiodides and binary metal iodide-iodine compounds have been prepared and investigated by means of X-ray diffraction, EXAFS, far-IR, Raman, UV-vis and NMR spectroscopy and quantum chemical calculations. (Et3S)[AuI4].2I2 and (Me3S)[Cd2I6]1/2.3I2 were synthesised through the reaction between the room temperature melt of trialkylsulfonium polyiodides and the corresponding metal iodides. The structu
Feedback interconnections of causal linear systems are studied in a continuous-time setting. The developments include a linear time-varying (LTV) generalization of Vinnicombe's nu-gap metric and an integral-quadratic-constraint-based robust L2-stability theorem for uncertain feedback interconnections of potentially open-loop unstable systems. These main results are established in terms of Toeplitz
Proton exchange membrane (PEM) fuel cells have been promoted due to significant breakthroughs in various aspects and increasing public interests. The porous features of the gas diffusion layer (GDL) and the necessary assembly processes generate localized pressure forces on the channel/shoulder structure of the bi-polar plates (BPP). As a consequence, the assembly pressure acting on a single cell a
A method for optimization of PID controller parameters and measurement filter time constant is presented. The method differs from the traditional approach in that the controller and filter parameters are simultaneously optimized, as opposed to standard, sequential, design. Control performance is maximized through minimization of the integrated absolute error (IAE) caused by a unit step load distur
Efficient conjugation between biomolecules and electrode materials is one of the main challenges in the field of biosensors. Cellobiose dehydrogenase (CDH) is a monomeric enzyme, which consists of two separate domains: one catalytic dehydrogenase domain (DHCDH) carrying strongly bound flavin adenine dinucleotide (FAD) in the active site and a cytochrome domain (CYTCDH) carrying a b-type heme conne
PURPOSE: Adjuvant chemotherapy versus observation and chemotherapy at progression was evaluated in 162 patients in a prospective randomized multicenter study. We also evaluated DNA-measurements as an additional prognostic factor.PATIENTS AND METHODS: Patients received adjuvant carboplatin AUC 7 every 28 days for six courses (n = 81) or no adjuvant treatment (n = 81). Eligibility included surgicall
cDNA encoding rat alpha 1-microglobulin-bikunin was ligated into the transfer vector pVL 1392 and recombined with a wild-type baculovirus. The resulting alpha 1-microglobulin-bikunin-encoding baculovirus was used to infect Trichoplusia ni (Hi-5) insect cells. The infected cells secreted alpha 1-microglobulin with maximal concentrations of 15 mg/liter 5 days after infection. The secreted proteins m
Calculations of unsteady two-dimensional-flow around rectangular cylinders at incidence are presented. The Reynolds numbers are low ( ⩽ 200), so that the flow presumably is laminar. The results are in reasonable agreement with the indeed scarce experimental data available at these low Reynolds numbers. An incompressible SIMPLEC code is used employing non-staggered grid arrangement. A third-order Q
The ongoing environmental crisis and the growing socio-economic disparities between different population groups are among the most significant challenges facing humanity. These problems are rooted in unsustainable consumption patterns, particularly in the more affluent societies worldwide. We, therefore, need to change existing consumption patterns, which is a considerable challenge. A sustainable
PURPOSE: Acquired chemoresistance is a frequent event in small cell lung cancer (SCLC), one of the deadliest human malignancies. Histone deacetylase inhibitors (HDACi) have been shown to synergize with different chemotherapeutic agents including cisplatin. Accordingly, we aimed to investigate the dual targeting of HDAC inhibition and chemotherapy in SCLC.EXPERIMENTAL DESIGN: The efficacy of HDACi
N-type doping of the bulk-heterojunction layer in nonfullerene organic solar cells allows to effectively ameliorate inferior electron transportation by filling traps and optimizing electron pathways, leading to a better balance of charge transport in device. This mechanism, however, provides an incomplete understanding of the stronger photogeneration, long-lived excitons and simultaneously increas
