Changes in the quality indices during ice storage of farmed Senegalese sole (<Emphasis Type="Italic">Solea senegalensis</Emphasis>)

Farmed Senegalese sole (Solea senegalensis) from two different cultivation areas in Spain and different rearing conditions were analyzed up to 28 days in order to establish changes in the quality indices during ice storage and select the best ones to be used to calibrate a prototype designed for rapid measurement of freshness in this species. The main indices measured were the degradation of adenosine-5′-triphosphate and breakdown products, K-value, Torrymeter readings, trimethylamine oxide nitrogen (TMAO-N), TMA-N, TBA index and dielectric measurements. The main differences observed were related to size, amount of TMAO-N, pH and fat content, which may be related to differences in the rearing conditions. The most consistent index to measure changes in freshness was the K-value that showed a linear response with time during the shelf-life period, irrespectively of the differences of size and composition of the fish in both batches. However, the dielectric response of the fish varied in the two batches in the pulse amplitude. More work is needed in order to adjust the prototype for predicting the days in ice for this species.

Risk factors for increased rates of sole ulcers, white line disease, and digital dermatitis in dairy cattle from twenty-seven farms in England and Wales

Claw lesion treatment records were recorded by farmers on 27 dairy farms (3,074 cows, 36,432 records) in England and Wales between February 2003 and February 2004. These were combined with farm environment and management data collected using a combination of direct observations, interviews with farmers, and milk recording data. Multilevel models were constructed for the 3 most frequently reported lesions related to lameness, namely, sole ulcers, white line disease, and digital dermatitis. Risks associated with an increased incidence of sole ulcers were parity 4 or greater, the use of roads or concrete cow tracks between the parlor and grazing, the use of lime on free stalls, and housing in free stalls with sparse bedding for 4 mo or more. The risks for white line disease were increasing parity and increasing herd size, cows at pasture by day and housed at night, and solid grooved concrete floors in yards or alleys. Solid grooved flooring was also associated with an increased risk of digital dermatitis, and cows 6 or more months after calving had a decreased risk of a first case of digital dermatitis. These results improve our understanding of the specific risks for 3 important lesions associated with bovine lameness and could be used as interventions in future clinical studies targeted at the reduction of specific lesions.

论“装置型”运动鞋底设计

"装置型"鞋底是在运动鞋底设计了一个特殊构造的装置,它能够在穿着者运动时提供比传统材料型运动鞋更加充裕的缓冲保护和反作用力,并且使鞋的自重更轻盈。"装置型"鞋底结构精巧,形态各异,技术含量高。它已经成为运动鞋设计的重点、商业竞争的重要手段和市场营销的关键卖点。虽然存在缺点和瑕疵,但"装置型"鞋底设计在构型上推陈出新、不断完善,已成为运动鞋发展的主要动力。     

鞋底BMP图像的处理及其矢量化

鞋底形状和花纹设计通常采用扫描或数码照相生成象素点格式BMP位图，矢量化前采用低通／高通等线性滤波，或平均／中值／最大值／最小值等非线性将其转换为向量格式，再通过二进制对比度处理和包括腐蚀与膨胀等运算的二值图像处理，形成灰度图，最后采用Type3软件将其矢量化，并通过CAD软件修整，生成鞋底形状和花纹的向量图，实现鞋底的反求设计。     

Moisture content, thickness, and lesions of sole horn associated with thin soles in dairy cattle

Thin soles and resulting lameness are often associated with increased culling rates in large dairy operations. The moisture content of the sole horn may cause the horn to be softer, thus predisposing it to an increased rate of wear. For that reason, the first objective of this study was to determine the moisture content of the sole horn of thin-soled cows. The second objective was to document physical changes of the claw associated with thin soles. Twenty-six adult Holstein cows showing signs of thin soles, and 16 normal cows were used in the study. Selection criteria for thin-soled cows included a dorsal wall length of less than 7.5 cm and the following clinical signs: painful gait, arched back, and specific leg lameness. Sixteen normal adult cows with dorsal wall length in excess of 7.5 cm were randomly selected. For thin-soled cows, the moisture contents of sole horn were 37.1 +/- 0.7% for front claws and 40.5 +/- 0.7% for rear claws. These values were significantly different from each other. Moisture contents of sole horn from normal cows were 31.08 +/- 0.93% for front claws and 33.1 +/- 0.9% for rear claws, which were significantly different from each other and different from thin-soled cows. Rear claws had higher moisture contents than front claws. Mean sole horn thickness was 4.23 +/- 0.18 mm for the rear lateral claws and 5.15 +/- 0.18 mm for the rear medial claws. The average dorsal wall lengths were 66.8 +/- 3.94 mm for rear lateral claws and 69.1 +/- 7.25 mm for rear medial claws. Thirty percent of rear feet with thin soles had pathological claw horn lesions including sole/white line separation (72%) and sole ulcers (28%). Of the affected claws, 13% had more than one lesion. Seventy-seven percent of claw lesions occurred in the lateral claw.
