Transverse-momentum and pseudorapidity distributions of charged hadrons in pp collisions at âs=0.9 and 2.36 TeV
Measurements of inclusive charged-hadron transverse-momentum and pseudorapidity distributions are presented for proton-proton collisions at root s = 0.9 and 2.36 TeV. The data were collected with the CMS detector during the LHC commissioning in December 2009. For non-single-diffractive interactions, the average charged-hadron transverse momentum is measured to be 0.46 +/- 0.01 (stat.) +/- 0.01 (syst.) GeV/c at 0.9 TeV and 0.50 +/- 0.01 (stat.) +/- 0.01 (syst.) GeV/c at 2.36 TeV, for pseudorapidities between -2.4 and +2.4. At these energies, the measured pseudorapidity densities in the central region, dN(ch)/d eta vertical bar(vertical bar eta vertical bar and pp collisions. The results at 2.36 TeV represent the highest-energy measurements at a particle collider to date

Artificial cooling as an alternative to increase productivity and welfare of steers under heat stress Resfriamento artificial como alternativa para aumentar o bem-estar de novilhos sob estresse tĂŠrmico
The effects of a cooling system on productive efficiency and welfare of Holstein steers were evaluated during the summer. Sixty steers in the finishing phase were randomly allotted to one of two treatment-groups. Animals of control group were only provided with shade (non-cooled group) and a group of animals under a cooling system were installed in the shaded area (cooled group), which were operated daily from 09am to 6pm during the 69d of the study. The averages of environmental temperature and relative humidity were 35.4°C and 35.3%, respectively, with a temperature-humidity index average of 81.4 during the study. Individual body weight was recorded every two weeks, while body surface temperature and respiratory frequency were recorded three times per week. Blood samples were biweekly taken from coccygeal vein for determination of T3 and T4. The average daily gain in the cooled group gain (1.46kg/d) was similar (P=0.21) to non-cooled group (1.37kg/d). Body surface temperature (35.9ÂşC vs 38.7ÂşC) and respiratory frequency per minute (77 vs 104) were lower (P<0.01) in the cooled group than in non-cooled group, respectively. Triiodotironine levels were similar (P=0.30) in cooled (0.80ng/mL) and non-cooled (0.87ng/mL) groups, while, tiroxine level was lower (P<0.01) in cooled group (44.0ng/mL) compared to non-cooled group (56.6ng/mL). The cooling system did not improve productive parameters but the welfare in the cooled group was increased.<br>Avaliou-se um sistema de resfriamento para aumentar a eficiĂŞncia produtiva e o bem-estar de novilhos durante o verĂŁo. Utilizaram-se 60 animais em fase de acabamento, distribuĂdos aleatoriamente em dois grupos: os do grupo-controle permaneceram somente sob sombra (grupo nĂŁo resfriado) e os do grupo sob sistema de resfriamento, sob ĂĄrea sombreada, diariamente, das 9 Ă s 18h, durante 69 dias de estudo. As mĂŠdias registradas de temperatura ambiente e umidade relativa foram 35,4°C e 35,3°C, respectivamente, com Ăndice de temperatura-umidade de 81,4 durante o perĂodo de estudo. O peso individual foi anotado a cada duas semanas, e a temperatura da superfĂcie corporal e a frequĂŞncia respiratĂłria foram registrados trĂŞs vezes por semana. Amostras de sangue foram tomadas da veia coccĂgea duas vezes por semana para determinação de T3 e T4. O ganho mĂŠdio diĂĄrio no grupo sob resfriamento (1,46kg/dia) foi similar (P=0,21) ao do grupo-controle (1,37kg/dia). A temperatura da superfĂcie corporal (35,9°C versus 38,7°C) e a frequĂŞncia respiratĂłria/minuto (77 versus 104) foram mais baixas (P<0,01) no grupo sob resfriamento do que no grupo-controle (P<0,01), respectivamente. NĂveis de triiodotironina foram similares (P=0,30) em animais com resfriamento (0,80ng/mL) e sem resfriamento (0,87ng/mL), enquanto o nĂvel de tiroxina foi mais baixo (P<0,01) no grupo com resfriamento (44,0ng/mL versus 56,6ng/mL). O sistema de resfriamento nĂŁo afetou parâmetros produtivos, porĂŠm o bem-estar dos animais do grupo com resfriamento foi melhor

Glycodendrimers: versatile tools for nanotechnology
Combining nanotechnology with glycobiology has triggered an exponential growth of research activities in the design of novel functional bionanomaterials (glyconanotechnology). More specifically, recent synthetic advances towards the tailored and versatile design of glycosylated nanoparticles namely glyconanoparticles, considered as synthetic mimetics of natural glycoconjugates, paved the way toward diverse biomedical applications. The accessibility of a wide variety of these structured nanosystems, in terms of shapes, sizes, and organized around stable nanoparticles have readily contributed to their development and applications in nanomedicine. In this context, glycosylated gold-nanoparticles (GNPs), glycosylated quantum dots (QDs), fullerenes, single-wall natotubes (SWNTs), and self-assembled glycononanoparticles using amphiphilic glycopolymers or glycodendrimers have received considerable attention to afford powerful imaging, therapeutic, and biodiagnostic devices. This review will provide an overview of the most recent syntheses and applications of glycodendrimers in glycoscience that have permitted to deepen our understanding of multivalent carbohydrate-protein interactions. Together with synthetic breast cancer vaccines, inhibitors of bacterial adhesions to host tissues including sensitive detection devices, these novel bionanomaterials are finding extensive relevance
