It was not until the end of the 1990’s that animal born satellite receivers catapulted range cattle ecology into the 21st century world of microchip technology with all of its opportunities and challenges. With the global navigation satellite system (gNSS), insight about how cattle use a landscape is being revealed from previously unknown temporal and spatial behaviors. The most common system to date for studying ungulate movement is the global positioning system (gPS). With its use has come a clarity and completeness in documenting spatial and temporal data in new and exciting ways that offer almost unlimited possibilities to better understand and manage economic and societal returns from animal dominated landscapes. However, its use on free-ranging cattle is not without challenges, some of which are yet to be optimally solved. To maximize the usefulness of gNSS data, consideration must be given to: 1) developing a standardized protocol for reporting and analyzing research that facilitates interpretation of results across different ecosystems;2) develop optimum ranges over which to collect satellite fixes depending upon the particular behaviors of interest;and 3) concurrently develop electronic hardware and equipment platforms that are easily deployed on animals and that are light, robust, and can be worn by cattle for extended periods of time without human intervention (e.g., changing batteries). Once data are collected, appropriate geographic information system (gIS) based models should be used to produce a series of products that can be used to implement flexible management strategies, some of which may support methodologies that are yet to be commercialized and adopted into future plant-animal interface management routines.

<i>Ustilaginoidea virens</i>Infection of Rice in Arkansas: Toxicity of False Smut galls, Their Extracts and the Ustiloxin Fraction

＜正＞ Objective: To characterise the spontaneous electrical activity in prostates of immature and older guinea - pigs. Methods: Prostates were removed from guinea pigs（300 - 1200g） killed humanely. Electrical activity from the guinea - pig prostate was recorded using intracellular microelectrodes. Results: Four types of electrical activity were recorded in the guinea - pig prostate. In young animals the majority of electrical recordings comprised of slow wave activity （88 %） which consisted of a depolarising component with several superimposed nifedipinesensitivespikes （n = 36）. Pacemaker activity consisted of a simple waveform of alternating depolarising and repolarising phases and was recorded in 5% of cells;the remaining cells exhibited spike potential discharge （7 % ）. In contrast, the most prevalent electrical activity recorded in the older prostates （56% ） was spike potentials （n = 22）. Slow wave activity was recorded in 28 % of cells （n = 11）. standard transient depolarisations comprised 15% of all electrical recordings and pacemaker potentials were not observed. Conclusion: With age. there is a change in the proportion of cells exhibiting slow wave activity.

American Journal of Plant Sciences 2014年第21期5卷 3166-3176页

Cool, wet conditions in the southern US during the maturing stages of rice in 1998 contributed to outbreaks of false smut caused by Ustilaginoidea virens. Water extracts of false smut galls in Asia have been reported to contain ustiloxin toxins, cyclic peptide antibiotics that interfered with microtubule function and caused “lupinosis”-like lesions in mice. Cell-free extracts from false smut galls on rice grown in Arkansas were fractionated by a published procedure for the purification of ustiloxins. The ustiloxin fraction was phytotoxic to Lemnapausicostata (duckweed) at ≥19 μg/ml, but the host plant, rice, was much less susceptible, exhibiting phytotoxic effects in germinating seeds at ≥1000 μg/ml. The aqueous extract of rice false smut galls showed no cytotoxicity to mammalian cell cultures at 200 μg/ml, but the ustiloxin fractionwas cytotoxic at 10 - 100 μg/ml. However, rice false smut galls were not toxic when fed to mice at 10% of chow, but caused feed refusal at higher concentrations. We conclude that for 1) the U. virens which causes false smut in southern USA differs from Asian isolates in that does not produce detectable ustiloxins;and 2) false smut affects the appearance, but not the food safety of rice in the United States.

生坯切削加工的好处已众所周知 ,如切削刀具的寿命较长 ,能够用可烧结硬化粉末制作形状复杂的零件等。零件生坯强度高可防止在运送过程中生坯开裂与损坏。但是 ,用常规粉末冶金工艺不易达到所要求的高生坯强度 (约大于 2 0MPa)。因此 ,生坯切削加工尚未得到广泛应用。用魁北克金属粉末公司 (QMP)新开发的高生坯强度 (highgreenstrength ,简称HgS)聚合物润滑剂 ,正在消除使用生坯切削加工的限制。这种润滑剂的一个杰出特性是其对温度的敏感性。在压制温度 5 5℃下整个坯件就能获得高生坯强度 ,这用冷压很容易达到。若将零件生坯压制到密度 6 8g/cm3 ,随后经固化处理 ,甚至可将生坯强度增高到 4 8MPa左右。这样高的生坯强度使得用常规粉末冶金工艺制造的零件都能进行生坯切削加工。本文介绍了用正时链轮进行生坯切削加工试验的一些结果。使用的材料是由QMPATOMET 4 6 0 1与HgS润滑剂组成的可烧结硬化的粉末混合料。先用冷压将链轮压制到密度约 6 8g/cm3 ,再对用压制的生坯与经固化处理的生坯进行切削加工 (在齿的中间车槽 )。结果表明 ,HgS润滑剂 ,特别是固化处理后 ,可赋予生坯足够高的强度 ,以进行装卡与切削加工作业。切削加工表面光滑且棱边完好。由可烧结硬化粉末制作的可生坯切削加工的链轮。
