Documentation is a major component of any traceability system where traceability is defined in the ISO Regulation 8402:1994 as the ability to trace the history, application and location of what is under consideration. Traceability systems are record keeping systems designed to track the flow of product or product attributes through the production process or supply chain. All international supply chains are forced to comply with traceability requirements. In this paper, we develop and implement an end-to-end mobile application prototype that traces the poultry production. This application consists of front-end and back-end systems. At the front-end, the worker uses a GPRS enabled handheld device (cell phone, PDA, etc.) to capture information on poultry operations collected at a remote chicken farm and transmit it to a back-end server in the main office. Through customized application the back-end server analyses all information received from the front-end and based on a built-in business process and business rules, intelligently updates various stakeholders of any breach of bio-security measures that requires immediate attention. The proposed system administrators can also access this application via Internet for management decision making. The back-end system consists of web server, defined business application logic and database server.  相似文献   

泡核桃壳棕色素的提取和稳定性研究     

周萍  许兴景  王敏  董艺  胡文帅  任媛媛 《安徽农业科学》2011,39(7):3912-3913,3983

[目的]研究泡核桃壳棕色素的最佳提取条件及粗提色素的稳定性。[方法]以漾濞泡核桃壳为原料,研究浸提温度和时间对色素提取效果的影响,确定最佳提取条件,并对粗提色素进行了稳定性试验。[结果]色素的最佳提取条件为：在75℃时,用1%NaOH提取3次,每次浸提时间为2h。在此条件下,色素的提取率较高,达31%。粗提色素的稳定性试验表明,该色素在酸性条件下稳定,有一定的耐光性,对还原剂的耐受性较强,但对氧化剂的耐受性较差,不适宜高温处理,且不同金属离子对色素有不同影响。[结论]该研究为泡核桃壳的推广应用提供了理论基础和实验依据。  相似文献

Aldh3a2a敲除对斑马鱼体色的影响     

卢培钰  冯毅栋  鲍宝龙 《上海海洋大学学报》2024,33(2)

本研究探讨了Aldh3a2a在斑马鱼色素细胞发育中的意义及其对醛代谢和肝脏健康的影响。利用CRISPR/Cas9技术,我们成功敲除斑马鱼体内的aldh3a2a,导致黑色素细胞、黄色素细胞和虹彩细胞合成数量减少。转录组分析揭示了基因表达谱的变化,特别是与钾通道和类固醇生物合成途径相关的基因表达谱。我们的研究结果表明,aldh3a2a和aldh1a2之间存在调控关系,对视黄酸受体信号传导有影响。GO和KEGG富集分析强调了对色素细胞发育以外的细胞过程的更广泛影响。此外,aldh3a2a基因敲除会导致醛积累,导致肝脏异常,类似于Sj?gren-Larsson综合征,本研究揭示了aldh3a2a在斑马鱼中的多方面作用及其与人类遗传疾病的相关性。  相似文献

Evaluation of efficacy of several disinfectants against Campylobacter jejuni strains by a suspension test     

Gutiérrez-Martín CB  Yubero S  Martínez S  Frandoloso R  Rodríguez-Ferri EF 《Research in veterinary science》2011,91(3):e44-e47

The objective of this study was to determine the efficacy of 16 active compounds and 11 commercial disinfectants against Campylobacter jejuni. Two reference strains (one of avian origin and the other isolated from bovine) and two avian field strains were tested in suspension test in the presence and absence of serum. Chloramine-T, povidone–iodine (1% available iodine), cetylpiridinium chloride, ethanol, isopropanol, chlorhexidine digluconate, formaldehyde, phenol, and 10 of the 11 commercial formulations (eight of them based on quaternary ammonium compounds) showed an excellent disinfectant capability, resulting in the highest level of reduction (>6-log₁₀) in colony-forming units of the four C. jejuni strains compared regardless of the presence or absence of organic material. These compounds might be helpful in the adoption of environmental control measures against C. jejuni.  相似文献   

A simple and efficient method for isolation of a single Eimeria oocyst from poultry litter using a micromanipulator     

Dongjean Yim  Sang S. Kang  Wongi Min 《Research in veterinary science》2011,90(2):260-261

The chicken, which is the host for seven species of Eimeria, typically is infected simultaneously by multiple Eimeria species and the oocysts of coccidia are excreted in the feces. A prerequisite for investigation of individual Eimeria species is to isolate a single oocyst from fecal samples. A novel method for isolating a single Eimeria oocyst from poultry litter using a micromanipulator was developed. This simple method is fast and reliable, and provides direct isolation of a single sporulated oocyst from fecal samples harboring multiple Eimeria species or samples contaminated by other species of parasite.  相似文献
