    Multi-boson Measurements in CMS

    Full text link
    Recent results from the CMS experiment on the production of multiple vector bosons in proton-proton collisions at the CERN LHC are presented. Measurements of WZ and ZZ production with fully leptonic decays, Z(νν)γ(\nu\nu)\gamma, and WV (V == W,Z →qqˉ\rightarrow q\bar{q}) production at 8 and 13 TeV are discussed. Selected cross section measurements, unfolded differential measurements, and limits on anomalous triple gauge couplings are presented and compared with theoretical predictions.Comment: LHCP 2017 Proceedings, CMS CR-2017/36

    The Trouble with Connecticut

    Get PDF
    The problems of Connecticut, this author believes, parallel those of Nigeria, which are described by Chinua Achebe in The Trouble with Nigeria. Both places may be considered dirty, callous, ostentatious, and dishonest. The causes of these and other defects are also similar: unusually large disparities in living standards, high cost of living, localism, and lack of leadership. In Connecticut, gross inequities in taxation seem to intermingle with and reinforce all these roots of unpleasantness

    Cultivating nutrition

    "Over the past decade, donor-funded policies and programs designed to address undernutrition in the Global South have shifted away from agriculture-based strategies toward nutrient supplementation and food fortification programs. Given the potential benefits resulting from agriculture-based nutrition interventions, this study uses Q methodology to explore the views of a range of stakeholders from both developed and developing countries on the value of—and constraints related to—gender-sensitive, nutrition-oriented agricultural projects. The three distinct viewpoints that emerge from this exercise all support the use of agricultural strategies to improve nutrition and underline the importance of gender-sensitive approaches. The viewpoints differ, however, on the relative importance of nutrition education, the strategic use of nutrient supplementation and food fortification, and the degree to which agriculture-based approaches have an impact on nutrition. The findings indicate that there is common ground among a range of stakeholders—donors, researchers, policymakers, and program practitioners—on the benefits of agriculture and gender-sensitive strategies to improve nutrition. These areas of agreement can serve as a foundation for forging an effective integrative strategy to improve nutrition that includes gender-sensitive agricultural approaches."

    Manure management education and demonstration project

    Proper methods and rates for applying livestock manure to crop land are critical to preserve water quality. The growth and concentration of Iowa\u27s swine production facilities in recent years pose environmental concerns in terms of manure application to agricultural land. This project demonstrated a feasible, economical testing program to evaluate the nutrient content of livestock wastes. A portable kit was used that can test for ammonia nitrogen and phosphorus in both liquid and solid manure, facilitating on-site, immediate testing. The results of this on-farm testing kit, which is currently available to producers, were then compared with laboratory analysis to determine the kit\u27s accuracy. By analyzing the nutrient value of manure immediately prior to land application, producers can make more environmentally sound manure management decisions

    Calcium and magnesium absorption and retention by growing goats offered diets with different calcium sources

    Calcium addition is necessary in order to balance the high phosphorus concentrations that are characteristic of high-concentrate ruminant diets. However, calcium sources differ in their bioavailability. Our objective was to determine apparent calcium and magnesium absorption and retention in goats offered diets containing different sources of calcium. Spanish-Boer goats (n = 18; 19.6 ± 1.88 kg) were stratified by body weight (BW) and sex and randomized to dietary treatments consisting of Purina Antlermax 16 containing either calcium carbonate (CC), Calmin (CM) or Milk Cal (MC). Goats were adapted to a control, corn-based high-concentrate diet on pasture and then moved to individual 1.0 × 1.5-m pens with plastic coated expanded metal floors, and adjusted to their respective diets along with removal of hay from the diet over a 7-d period. Goats were then offered their respective diets at a total of 2% of BW in equal feedings at 8:30 AM and 5:00 PM for an additional 14-d adaption period to diet and facilities followed by a 7-d collection of total urine and feces. Data were analyzed using PROC MIXED of SAS. Calcium and magnesium intake were not different (P ≥ 0.12) among diets. Calcium and magnesium apparent absorption and retention (g/d and % of intake) were greatest (P \u3c 0.05) in goats offered CC and did not differ (P ≥ 0.20) between goats offered the CM and MC diets. Therefore, calcium and magnesium were more available for goats from the diet containing calcium carbonate compared with diets containing Calmin and Milk Cal
