棉花加工厂电子设备的静电防护

前言 近年来网络技术和现代测控技术在棉花加工行业得到了越来越广泛的应用,各种各样的电子设备越来越多地应用到了加工厂的生产、检验、管理岗位上。例如已经得到广泛应用的棉包条码信息管理系系统、籽棉收购系统、棉花加工设备的故障诊断及检测系统等等。这些技术的应用极大地节省了人力,提高了生产效率,增加了企业的经济效益。但是也带来了一些新问题,对操作人员的技能要求更高、设备的保养维护专业性更强等等。对这些电子设备进行操作和维护工作过程中,经常会出现正常运行的设备突然出现工作异常或损坏;或者在维护之前工作正常,进行了设备维护之后出现了故障;或者设备时好时坏,性能逐渐变差直至彻底不能使用。具体的事例有：籽棉收购系统中计算机对磅房电子秤的数据读取过程中偶尔出现数据不稳定,但大多数时间是正常的。棉包条码信息管理系系统换完色带或进行完其它操作之后,出现打印机打印乱码或者无法打印等故障。计算机在拔插外部串口设备后,计算机串口损坏,等等。所有这些都可能与一种物理现象有关,“静电放电”。

标签打印中的热转移和热敏技术与材料

<正> 在生产库存管理和产品打印中,都需要处理大量的可变信息,如品种、生产日期、价格等。普遍来说,这些信息由电脑输入,以条形码形式显示出来,再通过打印机,打印在不干胶标签上。这种信息的处理和传递的精确度极高,大大减少了人工记录可能出现的误差,提高了信息管理的效率。由于条形码标签的打印效果会直接影响到条码扫描的准确度,亦即影响到信息的精确处理,所以条形码的打印要求影像密度高、边界清晰。

National estimates of the body composition of British cattle, sheep and pigs with special reference to trends in fatness. A review

National carcass classification records for cattle, sheep and pigs were used as a basis for estimating the body composition of British livestock slaughter populations. The tissue percentages of carcasses in each classification fatness range were estimated from regression equations constructed using data from breed comparison trials and other sources. The lipid and protein contents of the tissues were then estimated using regression equations from body composition studies. The mean carcass composition, and lean and fat production from current populations (1984) were compared with those of ten years ago. There has been an important increase of 20 kg (8%) in carcass weight for beef but no change in carcass composition. The average beef carcass in 1984 was estimated to contain 23% lipid (inclusive of lipid in perinephric and retroperitoneal fat). The weight of sheep carcasses has fallen by 0·6 kg (3 1 2% ) since 1977 without any appreciable change in carcass composition. The average sheep carcass in 1984 was estimated to contain 24% lipid. The lipid content of the average pig carcass was estimated to have fallen significantly from 27% in 1975 to 22% in 1984, with a small increase in carcass weight.     

REALIMENTATION OF CULL BEEF COWS. I. LIVE PERFORMANCE, CARCASS TRAITS AND MUSCLE CHARACTERISTICS

The objective of this study was to determine whether culled beef cows fed a high-concentrate diet (FED) would have improved live performance, carcass traits and muscle characteristics compared with forage fed (CON) cows. In addition, ractopamine (RAC) supplementation was evaluated for added benefits over high concentrate alone. Live weight, average daily gain, hot carcass weight, ribeye area, marbling, quality grade and carcass fat measurements increased ( P ≤  0.05) by realimentation. As a percent of hot carcass weight, muscle yields did not differ ( P >  0.05). Lipid content increased ( P ≤  0.05) in 5 out of the 10 muscles from FED cows. Cows fed ractopamine showed some numeric improvements over feeding alone, but few statistical differences ( P >  0.05). This may result from variability associated with cull cows, and warrants investigation into the best dose/duration for ractopamine. However, realimentation by itself was able to improve cull cow quality.

PRACTICAL APPLICATION

The U.S. beef industry continues to explore new avenues to enhance undervalued sectors of the production system. Through realimentation, cull cow quality can be improved. The data presented herein demonstrate that feeding a high-concentrate diet to cull cows increases both live and carcass weights. In addition, high concentrate-fed cull cows display more marbling and whiter fat cover than those fed at maintenance level. Qualification for premium programs, heavier weights and overall higher quality may lead to increased value for this underutilized sector of the beef industry.     

Carcass characterisation of seven Spanish beef breeds slaughtered at two commercial weights

A total of 159 bulls representing seven Spanish beef breeds were fed with concentrates, managed in the same conditions and slaughtered at two commercial weights (veal and young-bull). Carcasses were measured and classified in order to characterise the carcass variation in the Spanish beef market and to assess the relationship among carcass measurements and grading. Principal Component Analysis clearly separated commercial types regardless the inclusion of the carcass weight in the input data. Within commercial weights the studied breeds clustered into three groups according to muscular development and carcass classification score: high meat producer breeds (Asturiana de los Valles and Rubia Gallega); medium meat producers (Parda Alpina and Pirenaica); and low meat producers (Avileña, Retinta and Morucha). The perimeter and width of the leg (muscular development) besides the length and width of the carcass basically defined these three carcass types. Conformation was an important trait in explaining variation between breeds because its values were positively correlated with muscular development and carcass compactness.     

CORRELATIONS BETWEEN SERUM CONCENTRATIONS OF LEPTIN AND BEEF CARCASS COMPOSITION AND QUALITY

Steers (n = 84) of various genotypes raised under diverse management conditions from the 2001 Missouri State Beef carcass contest were used to evaluate the relationship between serum concentrations of leptin and beef carcass composition and quality. Serum and carcass data including hot carcass weight; adjusted 12^th rib fat thickness; percentage kidney; pelvic and heart fat (KPH); marbling score; and USDA yield grades were measured at harvest. Leptin was correlated with back fat thickness over the 12^th rib, yield grade, and marbling score (r = 0.35, r = 0.19, r = 0.26 , P < 0.10; respectively), but not with hot carcass weight, ribeye area, or KPH (P > 0.10). Serum concentrations of leptin may be useful to objectively evaluate carcass composition in fed cattle and may provide a means by which carcass quality can be predicted in the live animal.     

The relationship of carcass measurements to carcass composition and intramuscular fat in Spanish beef

Forty beef carcasses were classified for conformation and fatness. Besides, carcass weight, fat thickness (FT), carcass dimension, marbling by computer image analysis and ultrasound readings was recorded to complement grading. For predicting intramuscular fat (IMF) content, FT, number of intramuscular flecks and conformation increased R²-value from 0.19 to 0.64 compared to conformation alone. For visual marbling, ultrasound readings and thoracic depth (TD) increased the R²-value from 0.24 to 0.57 compared to fatness score (FS). The best variables for predicting weight of fabricated subprimals were carcass weight or compactness which is a function of carcass weight (R² between 0.94 and 0.63). Fatness score was poorer than FT for predicting yield of subprimals cuts from round (R² = 0.16 vs. 0.50) and ultrasound readings for less valuable subprimals (R² = 0.31 vs. 0.39). These results showed that other variables could be used in combination with carcass fatness or conformation to achieve a more accurate estimation of fat and carcass yield.

Muscle profiling: Characterizing the muscles of the beef chuck and round

To fully characterize properties of the muscles of the beef chuck and round, and to reveal potential opportunities to upgrade the value, 39 different muscles were dissected from 142 beef carcasses differing in carcass weight, yield grade, and quality grade. Numerous physical and chemical properties of the muscles were determined. Muscle effects were observed for all traits (objective color, expressible moisture, proximate composition, emulsion capacity, pH, total collagen content, total heme-iron concentration, and Warner-Bratzler shear force). USDA quality grade generally had the most effect on muscle traits, with carcass weight and yield grade having lesser effects. These muscle profile data will allow for more informed decisions to be made in the selection of individual muscles from the beef chuck and round for the production of value-added products.
