Objectives: The objectives of this research are to 1) Formulate equation that shows the effect of pore aperture (or confinement) on not just the mass movement of molecules but the movement of individual molecules and 2) elucidate the derived equation and illustrate with diameter of pipes or tubes in literature. Place and Duration of Study: Department of Chemistry and Biochemistry, Research Division, Ude International Concepts LTD (862217), B. B. Agbor, Delta State, Nigeria; Owa Alizomor Secondary School, Owa Alizomor, Ika North East, Delta State, Nigeria. The research started between 2011 and 2013 and discontinued until March, 2018. Methods: Theoretical and calculational. Results: The results reaffirm that higher volume of gas flows through pore aperture of longer diameter than the shorter diameter. The same is applicable to longer tubes. The velocity of flow (volume of gas diffusing per cross-sectional area of pore aperture per unit time) is higher for shorter diameter of pore aperture than the longer diameter of pore aperture. The converse is the case for the entropy implicit in the flow of gas through pores of different diameter. Original Research Article Udema; AJOPACS, 6(3): 1-11, 2018; Article no.AJOPACS.41975 2 Conclusion: The “reduced velocity” is inversely proportional to the cube root of the diameter of the pore. The entropic value arising from the effect of diameter is directly proportional to natural logarithm of the square of half of the diameter. If the diameter of the pore is equal to the dB wavelength the gas molecule may continue its motion at a root mean square velocity.
目的:本研究的目的是:1)建立方程，表明孔径(或限制)不仅对分子的质量运动而且对单个分子的运动产生影响;2)阐明推导方程，并以文献中管道或管的直径来说明。学习地点和时间:尼日利亚三角洲州B. B. Agbor, Ude International Concepts LTD(862217)研究部化学和生物化学系;Owa Alizomor中学，Owa Alizomor，伊卡东北部，三角洲州，尼日利亚。这项研究始于2011年至2013年，直到2018年3月才停止。方法:理论与计算相结合。结果:结果再次证实，长孔径比短孔径的气体流量大。这同样适用于更长的管子。孔径越小，流速(单位时间内每孔径横截面积所扩散的气体体积)越高。相反，通过不同直径的孔隙的气体流动隐含的熵的情况。原创研究论文Udema;植物学报，6(3):1-11,2018;文章no.AJOPACS。结论:“减速速度”与孔直径的立方根成反比。由于直径的影响而产生的熵值与直径一半平方的自然对数成正比。如果孔的直径等于dB波长，气体分子可以以均方根速度继续运动。

This study determined heavy metal concentrations in soil, water and some vegetables such as (Spinach (Amaranth caudatus), Lettuce (Lactuca Sativa) and Tomato (Lycopersicon esculentum)) which were freshly harvested within five various farms (Samaila Hardaway farm, Mohammed Koli farm, MainaBabi farm, Ngatau farm and Sani Chansa farm) at Jawa village in Bade Local Government Area of Yobe state, Nigeria which were digested and analyzed for heavy metals such as As, Cd, Ni, Pb, and Cr. The aforementioned heavy metal concentrations were determined using Micro Plasma Atomic Emission Spectrophotometer MP-AES model 4200 of Agilent. The result of the analysis shows that all the heavy metals were detected and exceeded the World Health Organization (WHO) permissible limit. The metals were of the sequence As > Pb > Cd > Ni > Cr in the descending order. The high level of these heavy metals, especially arsenic place the consumers of these vegetable crops grown within the study area at health risk like cancer, kidney failure with time unless an urgent step is taken by relevant agencies to address this issue.

本研究测定了尼日利亚约贝州巴德地方政府区的贾瓦村5个不同农场(Samaila Hardaway农场、Mohammed Koli农场、MainaBabi农场、Ngatau农场和Sani Chansa农场)新鲜收获的土壤、水和一些蔬菜(如菠菜(Amaranth caudatus)、生菜(Lactuca Sativa)和番茄(Lycopersicon esculentum)中的重金属浓度，并对这些蔬菜进行了消化和分析，以检测砷、镉、镍、铅、砷、镉、镉和镉等重金属。上述重金属浓度采用安捷伦公司4200型微等离子体原子发射分光光度计MP-AES进行测定。分析结果表明，所有重金属都被检测出来，超过了世界卫生组织(WHO)的允许限量。金属元素的排列顺序为As > Pb > Cd > Ni > Cr。这些高水平的重金属，特别是砷，使研究区域内种植的蔬菜作物的消费者面临癌症、肾功能衰竭等健康风险，除非相关机构采取紧急措施解决这一问题。Oyekanmi et al.;植物学报，6(2):1-12,2018;文章no.AJOPACS。39560 2
