As the most important cultural practices for tea production, single effects of nitrogen (N) and potassium (K) fertilization on yield are well documented but their dynamics are poorly understood. It was necessary therefore to assess the dynamics of nitrogen and potassium in tea cultivation environment as influenced by fertilizer application rates. This objective led to a comprehensive field investigation in strongly acidic soils tea plots at Tea Research Foundation of Kenya, Kangaita substation in Kerugoya using clone TRFK 11-4 ina 3 × 3, N × K factorial RCB design. Treatments were nitrogen (0, 100 and 200 Kg N·ha-1·yr.-1) as urea and potassium (0, 40 and 80 Kg K2O·ha-1·yr.-1) as muriate of potash (moP) replicated thrice. Tea yield, plant biomass and plant nutrient concentrations were measured for calculation of plant nutrient uptake. Nutrients accumulated in the plants and removed from harvest were considered as nutrient loss, while fertilizer was considered as nutrient inputs gain to soil. In the interaction, there was no much difference between N-K treatments and crop N removal except mature and maintenance leaves, but there was a positive linear relationship between N applied and the yield of made tea and negative linear relationship between K applied and yield of made tea. The results from the study also showed that fertilizer inputs generally surpassed the crop nutrient demands (nutrient loss from harvest).

[背景]地址地理编码中的错误可能会影响空气污染对健康影响的估计。[目的]研究4种地理编码技术对采用小尺度(10m×10m)分散模型估计的城市空气污染与成人肺功能之间关联的影响。[方法]测量法国格勒诺布尔市354名成年居民的1秒用力呼气容积(FEV1)与用力肺活量(FVC)。这些居民参加了两个特征明确的研究:遗传和环境对哮喘影响的流行病学研究(EGEA)和欧洲共同体呼吸系统健康调查(ECRHS)。使用单个建筑物匹配作为参考方法以及三种空间插值方法编码家庭地址。使用扩散模型估计在进行肺功能测量前的12个月期间,每个参加者住址的Pm10和二氧化氮的平均浓度。以个体混杂因素及同日空气污染物暴露校正暴露与肺功能参数之间的关联。对地理编码技术在地理坐标之间距离、暴露估值以及暴露估值与健康影响之间关联等方面进行比较。[结果]利用建筑物匹配和三种插值技术估计坐标之间的中位数距离分别为26.4、27.9、35.6m。相对于基于建筑匹配的暴露估值,基于三种插值技术的Pm10浓度往往被高估。当使用建筑物匹配估计暴露估值时,Pm10每增加一个四分位数间距(3.0μg/m3),FVC%预测值下降3.72点(95%CI:-0.56～-6.88)、FEV1%预测值下降3.86点(95%CI:-0.14～-3.24)。当使用其他地理编码方法时,关联的幅度下降[例如,使用NavTEQ预测FVC%-2.81(95%CI:-0.26,-5.35),或者使用谷歌地图预测FVC%-2.08(95%CI:-4.63～0.47,P=0.11)。[结论]研究结果表明,当使用小尺度暴露模型估算空气污染暴露时,地理编码技术的选择可能会对健康影响的评估产生影响。

A method for etching the surface of a Pyrex glass substrate using the Reactive Ion Etching process without the use of masks is reported. Variations in the machined surface on an auxiliary plate, manufactured in aluminum and placed below a Pyrex glass slide, were transferred to the upper surface of the substrate. SF6 as etching gas and low pressure chamber to promote the increase of mean free path of ions were used. Two etching ratios were found, general, that affects the entire surface of the substrate, and differential, which generates the relief on the surface of the glass. Differential etching depth showed a linear behavior with respect to time;the mean differential etching rate obtained was 43 nm/min. The same phase between the auxiliary plate machining and the etched pattern on the substrate is preserved. With this technique it was possible to manufacture convex and concave surfaces;some examples are given. The arithmetic mean roughness achieved with the proposed method was found to be N1 class, ideal for the development of optical corrector plates.

Introduction: Pergularia tomentosa is a saharan spontaneous plant belonging to Asclepiadacea family. It has several medicinal properties and uses in the human food as an auxiliary in cheese-making. The purpose of this study is the extraction of the coagulant enzymatic system (C.E.S) from the plant dried leaves and its use in the preparation of fresh cheese. Materials & Methods: The determination of the coagulant activity was carried out on a skimmed milk powder by Berridge’s method. Cow’s milk used for coagulant strength determination and cheese-making. Proteolytic activity. The chemical determinations of raw milk were carried out according to AFNOR analysis methods. A descriptive sensory evaluation was performed to determine the organoleptic properties of the produced cheese. The proteolytic activity was determined by measuring the aspartyl-protease units. Results: The main results of the physico-chemical characterization show that its coagulant activity (R.U mL-1) was 97.19 ± 4.67, coagulant strength (SU) was 230.05 ± 0.37, proteolytic activity (μg·mL-1) was 0.33 ± 0.04 and coagulant activity/proteolytic activity ratio was 294.51. For the cheese made, it has presented the following results
