俄罗斯人选择什么鞋?

俄罗斯人喜欢两种低帮的皮鞋:一种是带有大约0.5厘米鞋跟的软皮鞋;另一种鞋跟要高些,大约是1.5厘米至2厘米大多数女性都倾向于选择第二种类型,她们不希望鞋跟过高穿着这种鞋跟高度的皮靴,相当舒适,而且无论是搭配裤装还是裙装都很合适。     

鞋跟的奥秘

自从人类创造了第一双“原始鞋”后的几十万年漫长岁月，“鞋”一直是没有跟的。起先它被叫做兽皮袜，以后又叫做无跟鞋。 直至十六世纪，欧洲才出现了鞋跟。最早使用鞋跟的是法国贵族。贵族的地位是至高无上的，鞋跟就是地位的标志。因此，贵族们争先恐后地增高鞋跟。     

运动鞋何以没有鞋跟?

绝 大多数皮鞋都有鞋跟,看上去美 观,穿起来挺拔,走起来轻快舒适。布鞋现在也大多都有鞋跟,然而运动鞋却大部分都没有鞋跟,这是为什么?很简单,鞋跟妨碍了运动。无论是打篮球排球,还是踢足球、打羽毛球、运动员不但要快速前进,而旦有时也要快速后退。

儿童机能鞋鞋垫跟杯高度与腰窝结构对行走稳定性的影响

鞋垫跟杯和腰窝处的结构对行走稳定性有重要影响,然而市面上很多儿童机能鞋鞋垫的设计存在缺陷。目前国内外的研究中,并没有专门针对儿童鞋垫跟杯高度以及腰窝结构对行走稳定性进行系统性研究,因此本文希望能够通过实验测试给出鞋垫跟杯高度和腰窝结构对儿童行走稳定性的具体影响。本实验测试了14名儿童在穿着不同跟杯高度、不同腰窝结构的鞋垫时足底压力中心运动轨迹,通过计算压力中心轨迹在X方向(侧向)和Y方向(前后方向)的相对偏移量Dxrel,Dyrel,相对运动距离Lx、Ly和相对平均速度Vxrel,Vyrel来评估行走时的稳定性。实验结果表明,跟杯高度和腰窝结构的变化,对儿童行走时侧向(X方向)的稳定性有显著影响,而对前后方向(Y方向)的稳定性则几乎没有影响。跟杯高度增加,侧向稳定性降低;而腰窝填充高度增加,侧向稳定性也增加。为了提高稳定性,机能鞋鞋垫的跟杯高度应选定在2~7 mm之间,腰窝填充高度应选定在1/2~3/4腰窝高度之间。本实验为儿童机能鞋鞋垫的设计提供了科学的参考依据。

Effects of breed and production system on lameness parameters in dairy cattle

The aim of the present study was to assess the effects of Holstein-Friesian (HF) and Norwegian (N) dairy cattle genotypes on lameness parameters in dairy cattle within different production systems over the first 2 lactations. Following calving, HF (n = 39) and N (n = 45) heifers were allocated to 1 of 3 systems of production (high level of concentrate, low level of concentrate, and grass-based). High- and low-concentrate animals were continuously housed indoors on a rotational system so that they spent similar amounts of time on slatted and solid concrete floors. Animals on the grass treatment grazed from spring to autumn in both years of the study, so that most animals on this treatment grazed from around peak to late lactation. Claw health was recorded in both hind claws of each animal at 4 observation periods during each lactation as follows: 1) −8 to 70 d postcalving, 2) 71 to 150 d postcalving, 3) 151 to 225 d postcalving, and 4) 226 to 364 d postcalving. Sole lesions, heel erosion, axial wall deviation, sole length of the right lateral hind claw (claw length), right heel width, and right lateral hind heel height were recorded as well as the presence of digital dermatitis. The N cows had lower (better) white line and total lesion scores than HF cows. Cows on the high- and low-concentrate treatments had better sole and total lesion scores than cows on the grass treatment. The HF cows had better locomotion scores than N cows. Breed and production system differences were observed with respect to claw conformation, including claw length, heel width, and heel height. Digital dermatitis was associated with worse sole lesion scores and interacted with production system to influence white line lesion scores and maximum heel erosion scores. This study shows that genetic, environmental, and infectious factors are associated with hoof pathologies in dairy cows.     

Heel erosion and other interdigital disorders in dairy cows: associations with season, cow characteristics, disease, and production

Epidemiologic associations between variables obtainable from dairy cow records and the occurrence of heel erosion, interdigital dermatitis, and interdigital hyperplasia at claw trimmings were estimated with multivariable logistic regression analysis on data from 1170 and 542 cows in lactation 1 and lactations 2 to 9, respectively. In the 17 herds, heel erosion, interdigital dermatitis, and hyperplasia occurred among 43.8, 4.5, and .9% of cows in lactation 1 and among 69.1, 7.6 and 5.9% of cows in lactations 2 to 9, respectively. Severity of heel erosion increased with parity, and risk increased with stage of lactation. Strong seasonal effects were present. Various combinations of veterinary treatments were associated with heel erosion and hyperplasia depending on parity, stage of lactation, and the presence of other claw disorders. In contrast, veterinary treatment had a protective effect for interdigital dermatitis in lactations 2 to 9. Severe degrees of sole ulcer increased the risk of heel erosion and interdigital dermatitis. The digital disorders were strongly associated in lactation 1 but not in later lactations. Heel erosion and hyperplasia were highly repeatable from one lactation to another.     

Short communication: Risk of severe heel erosion increased with parity and stage of lactation in freestall-housed dairy cows

Heel erosion is the most prevalent hoof lesion in housed dairy herds, particularly in freestall facilities. It is associated with hoof contact with manure slurry and abrasive floors. The objective was to assess changes in the risk of heel erosion from the dry period to mid lactation in primiparous and multiparous dairy cows. Nineteen pregnant primiparous cows, 22 late-lactation multiparous cows (parity = 3.2 ± 1.4; days in milk = 221 ± 38), and 16 nonlactating, pregnant multiparous cows (parity = 3.7 ± 1.4) housed in a freestall barn with concrete flooring were followed until mid lactation. The hind hooves of all the cows were examined approximately every 7 wk and heel erosion was scored. Multiparous cows more likely had heel erosion than primiparous cows (odds ratio = 11.0; 95% confidence interval = 3.7, 32.7). Time relative to calving showed a significant quadratic effect, revealing that the risk of heel erosion increased more rapidly as lactation progressed. Survival analysis showed that multiparous cows had a higher relative risk of developing heel erosion than primiparous cows (hazard ratio = 3.4). No cows improved between early and mid lactation, but 18 cows worsened. In conclusion, stage of lactation and parity were major risk factors for severe heel erosion in dairy cattle housed in freestalls.     

Effect of adsorption and regeneration temperature on irreversible adsorption of organic vapors on beaded activated carbon

This paper investigates the effect of adsorption and regeneration temperature on the irreversible adsorption of a mixture of organic compounds typically emitted from automobile painting operations. Adsorption of the organic vapors mixture onto microporous beaded activated carbon (BAC) and regeneration of the saturated BAC were completed under different conditions. Results indicated that increasing the adsorption temperature from 25 to 35 or 45 °C increased heel buildup on BAC by about 30% irrespective of the regeneration temperature due to chemisorption. The adsorption capacity (for the first cycle) of the mixture onto the BAC at these three temperatures remained almost unchanged indicating chemisorption of some of these compounds onto the BAC. Increasing the regeneration temperature from 288 to 400 °C resulted in 61% reduction in the heel at all adsorption temperatures, possibly due to desorption of chemicals from narrow micropores. BET area and pore volumes of the BAC decreased proportionally to the cumulative heel. Pore size distribution and pore volume reduction confirmed that the heel was mainly built up in narrow micropores which can be occupied or blocked by some of the adsorbates.     

高跟鞋鞋底结构优化以改善压力舒适性

随着广大女性对高跟鞋舒适性要求的提高,以及新型传感技术的压力测量仪器的发展和计算机技术的普及,足与鞋之间的压力情况越来越得到科研者与生产企业的重视。目前的研究大多停留在高跟鞋的跟高对足底压力分布的影响,而忽略了影响鞋底压力分布的一些其他次要的因素。这些因素虽不会像跟高一样明显地改变足底压力分布,但是却能缓解和改善高跟鞋因高跟而造成的不适,所以这些因素是我们进行鞋底结构设计时所必须探索的。
