加工・業務用ホウレンソウの生産現場においては，原料の安定供給を可能とするため収量予測技術が求められている．本研究では，気温および日射量が加工・業務用ホウレンソウの乾物生産に及ぼす影響を定量的に評価するため，まずは，気温および日射量が葉面積指数（LAI）および日射利用効率 （RUE）に及ぼす影響，ならびにLAIと群落による日射の遮蔽率（fi-SR）の関係を定式化した．LAIは積算気温を説明変数とするロジスティック曲線で近似された．平均RUEは0.98 g・MJ–1と推定され，RUEは前日から3日前までの平均気温を説明変数とする自然対数関数で近似された．また，今回対象とした加工・業務用ホウレンソウの群落において，fi-SRは1 – exp（–0.69 × LAI）によって近似され，LAIが3.26以上の範囲では0.89で一定となった．さらに，これらの関係を用いたモデルを作成し，異なる年度...

Corn milling byproducts are expected to increase dramatically in supply. Two primary types of milling processes currently exist, resulting in quite different feed products. The dry milling process produces distillers grains plus solubles, and the wet milling process produces corn gluten feed. These feeds can be marketed as wet feed, or they can be dried and marketed as either dry corn gluten fe...

BACKGROUND A new device for sterile docking, the Compodock (Fresenius NPBI Transfusion Technology), was developed for connecting PVC tubing for medical use while maintaining sterility. STUDY DESIGN AND METHODS Sterility of the connections was assessed by welding tubing with a heavy exterior contamination with Bacillus subtilis spores and also by welding in an environment contaminated with aer...

Cassava is a starchy root crop cultivated in the tropics for fresh consumption and commercial processing. Primary selection objectives in cassava breeding include dry matter content and micronutrient density, particularly provitamin A carotenoids. These traits are negatively correlated in the African germplasm. This study aimed at identifying genetic markers associated with these traits and unc...

A study of the after-ripening of ‘egusi’ melon [Citrullus lanatus (Thunb.) Matsun and Nakai] fruits was undertaken at the Teaching and Research farm of the University of Agriculture Makurdi in the wet and dry season productions of 2005 and 2007. The aim was to monitor its effects on seed quality. Fruits were harvested at two leaf colour stages [i.e. when leaves started turning yellow (LTY), and...

PURPOSE To evaluate the size and shape of commercially available polyvinyl alcohol (PVA) particles and to determine whether they change in size when suspended in nonionic contrast and in a solution of nonionic contrast and absolute alcohol. METHODS The two-dimensional area and the long and short axis of PVA particles from several different vendors were measured using a light microscope attach...

Cashew nuts are very nutritious but so well defended by caustic chemicals that very few species eat them. We investigated how wild bearded capuchin monkeys (Sapajus libidinosus) living at Fazenda Boa Vista (FBV; Piauí, Brazil) process cashew nuts (Anacardium spp.) to avoid the caustic chemicals contained in the seed mesocarp. We recorded the behavior of 23 individuals toward fresh (N = 1282) an...
