In Kenya, the government is promoting high-value and drought resistant crop varieties in an effort to reduce poverty in rural areas. Sugar beet is one such crop. This study was conducted with two objectives: 1) to assess the opportunities and challenges for sugar beet cultivation and adoption in the Nyandarua district of Kenya and 2) to assess whether sugar beet adoption can offer an opportunity f

It is argued that the focus of design is becoming increasingly intangible. At the same time as design consultants are expanding their offerings with new services aimed at enhancing innovation and the strategic process in client firms, studies indicate that industrial design consultancies have a problem getting commissioned and paid for the intangible parts of their service. One possible explanatio

Objectives: Within the European Prospective Investigation into Cancer and Nutrition (EPIC) study, the performance of 24-h dietary recall (24-HDR) measurements as reference measurements in a linear regression calibration model is evaluated critically at the individual (within-centre) and aggregate (between-centre) levels by using unbiased estimates of urinary measurements of nitrogen and potassium

De senast åren har produktionen alternativa drivmedel vuxit kraftigt. Drivkrafterna kan framförallt hänföras till ett växande intresse av att skydda klimatet och de politiska initiativ som följt av detta, stigande oljepriser och industriella och jordbrukspolitiska intressen. I svallvågorna av den kraftiga expansionen av biodrimvedel har dock debatten alltmer börjat ifrågasätta nyttan och effektern

ABSTRACT: Simultaneous saccharification and fermentation (SSF) is one process option for production of ethanol from lignocellulose. The principal benefits of performing the enzymatic hydrolysis together with the fermentation, instead of in a separate step after the hydrolysis, are the reduced end-product inhibition of the enzymatic hydrolysis, and the reduced investment costs. The principal drawba

Birds are assumed to use half of their cones (double cones) to detect fine spatial detail while their other half (single cones) is used for color vision. However, the spatial resolution of the color pathway in birds has never been studied. We determined the spatial contrast sensitivity to achromatic and isoluminant red-green and blue-green color gratings in budgerigars (Melopsittacus undulatus). C

Background: A previously discovered mutant of Saccharomyces cerevisiae alcohol dehydrogenase 1 (Adh1p) was shown to enable a unique NADH-dependent reduction of 5-hydroxymethylfurfural (HMF), a well-known inhibitor of yeast fermentation. In the present study, site-directed mutagenesis of both native and mutated ADH1 genes was performed in order to identify the key amino acids involved in this subst

Popular Abstract in Swedish Vad triggar kunskapsprocesser och kunskapsstrategier i projektbaserade organisationer? Sofia Pemsel, Institutionen för Byggvetenskaper, Lunds Tekniska Högskola. Inledning Vad avgör om en organisation har välutvecklade och fungerande kunskapsprocesser och färdigheter eller inte? Varför är vissa organisationer fantastiska på kundhantering medans andra är fenomenala i teThe beauty of projects lies in their ability to integrate different knowledge bases and expertise in novel ways. Projects, though, are temporary in nature and this has consequences for the organization that uses them as a business strategy to improve its efficiency. Project-based organizations are representative of this organizational form and can either be standalone or subsidiary organizations w

We present the results of a search for new, heavy particles that decay at a significant distance from their production point into a final state containing charged hadrons in association with a high-momentum muon. The search is conducted in a pp-collision data sample with a center-of-mass energy of 7 TeV and an integrated luminosity of 33 pb(-1) collected in 2010 by the ATLAS detector operating at

Background: Cadmium, a common food pollutant, alters DNA methylation in vitro. Epigenetic effects might therefore partly explain cadmium's toxicity, including carcinogenicity, but human data on epigenetic effects are lacking. Objectives: To evaluate effects of dietary cadmium exposure on DNA methylation, considering other environmental exposures, genetic predisposition, and gene expression. Meth

We report on InAs enhancement-mode field-effect transistors integrated directly on Si substrates. The transistors consist of vertical InAs nanowires, grown on Si substrates without the use of metal seed particles, and they are processed with a 50-nm-long metal wrap gate and high-kappa gate dielectric. Device characteristics showing enhancement-mode operation are reported. The output characteristic

The delimitation of two morphologically similar and not easily separable Vulpicida species,V. juniperinus and V. tubulosus, is analyzed using nuclear ITS and Mcm7, and mitochondrial SSU DNA sequences. Seventy-nine Vulpicida specimens, most from the two focal taxa, are included in the three-locus gene tree. The results from Bayesian and parsimony analyses are presented. There are strong conflicts b

Abstract Background: The WHO advises against recumbent or supine position for longer periods during labour and birth and states that caregivers should encourage and support the woman to take the position in which she feels most comfortable. It has been suggested that upright positions may improve childbirth outcomes and reduce the risk for instrumental delivery; however RCTs of interventions to en

Semiconductor superlattices may display dispersions that are degenerate either at the zone center or zone boundary [G. Bastard, Wave Mechanics Applied to Semiconductor Heterostructures, Monographies de Physique (Les Editions de Physique, Les Ulis, 1988); C. Sirtori, F. Capasso, D. L. Sivco, and A. Y. Cho, Appl. Phys. Lett. 64, 2982 (1994)]. We show that they are linear upon the wave vector in the

RATIONALE: Formoterol is approved as asthma rescue medication in many countries. The exact duration of the airway vs. systemic effects of formoterol compared with another rescue medication, salbutamol, has not been evaluated. OBJECTIVE: To assess the duration of airway bronchodilatory effects vs. systemic effects of inhaled formoterol and salbutamol in asthmatic patients. METHODS: Twenty-six patie

The welding of dissimilar alloys is seen increasingly as a way forward to improve efficiencies in modern aeroengines, because it allows one to tailor varying material property demands across a component. Dissimilar inertia friction welding (IFW) of two high-strength steels, Aermet 100 and S/CMV, has been identified as a possible joint for rotating gas turbine components and the resulting welds are

The thermodynamics and kinetics of formation of host-guest complexes between a series of bolaform surfactants of type C(n)Me(6)(2+)2Br(-) (n = 8, 10, and 12) and alpha-cyclodextrin and beta-cyclodextrin were studied with the aid of isothermal titration calorimetry (ITC) at 298.15 and 308.20 K. The association constant, the enthalpy, and the entropy of formation were determined. The obtained thermo

The hyaluronan (HA)-rich pericellular coat (PCC) enveloping most mammalian cells plays a vital role in biological processes such as cell adhesion, proliferation, motility and embryogenesis. In particular its presence on chondrocytes, which live in the load-bearing cartilage, has a wide range of implications in diseases such as osteoarthritis, highlighting its mechanical role in living organisms.
