Four phosphorus (P) levels (0, 15, 20 and 25 kg P ha -1 ) and three zinc (Zn) levels (0, 1.5 and 4kg Zn ha -1 ) were used in the study. The results of the study shown that stover and seed yield of mung bean improved with increasing phosphorus and zinc levels up to positive level. For instance, of Phosphorous the significant maximum stover yield (2.59 t ha -1 ) and seed yield (1.53 t ha -1 ) were obtained with the treatment P3 (25kg P ha -1 ) and the significant minimum stover yield (2.08 t ha -1 ) and minimum seed yield (1.43 t ha -1 ) were obtained with the treatment P0 (0kg P ha -1 ). In case of Zn the significant maximum stover yield (2.77 t ha -1 ) and maximum seed yield (1.77 t ha -1 ) were obtained with the treatment Zn2 (4 kg Zn ha -1 ) and the significant minimum stover yield (2.19 t ha -1 ) and minimum seed yield (1.38 t ha -1 ) were achieved with the treatment Zn0 (0 kg Zn ha -1 ).

The land was moderately fertile with clay loam soil type with pH 5.7. Two factors were used a) Spacing of transplanting b) Seedling number hill-1. Spacing of transplanting used was 15cm x 15cm (S1), 15 cm x 20 cm (S2), 20cm x 20cm (S3) and seedling number per hill were single seedling per hill, double seedling hill-1 and triple seedling hill-1. The experiment was laid in two factorial randomized complete block design (RCBD) with three replications. Effect of Spacing and seedlings number hill-1 was significant for most of the parameters except plant height, panicle length, straw yield and harvest index. Results revealed that maximum grain yield (3.40 t/ha) with mean harvest index 0.31 was found in 20cm x 20cm spacing. Similar results were obtained in case of effective tillers (8.55), filled grain/ panicle (89.42), Spikelet fertility (81.29%) and panicle length (26.04), where 20cm x 20cm spacing recorded the higher value compared to others. In case of Seedling number hill-1, Grain yield was found similar in all seedling number hill-1 but other parameters like effective tillers (9.12), filled grain/ panicle (87.57), Spikelet fertility (79.01%) and panicle length (26.65) were found statistically superior in triple seedling hill-1. The interaction between spacing and seedling numbers/ hill was found non-significant for all the parameters used in the research. 20cm x 20cm spacing with triple seedlings/hill was found superior in majority of parameters used. However, the results need to be confirmed for different aged seedlings used by farmers in Nepal.","PeriodicalId":87320,"journal":{"name":"Juniper online journal material science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48381221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Newton was taking tea under the apple trees in the family gardens at Woolsthorpe-England one summer’s afternoon in 1665 when an apple fell from an overhanging branch on the head, and immediately provided the inspiration for his law of gravitation. It may indeed have happened that way, but no one knows for certain. The story of Newton’s apple first appears in Voltaire’s Elements de la Philosophie de Newton, published in 1738, long after the great English mathematician had died and 73 years from the time the disputed apple fell. His only source for the apple story was Sir Isaac’s niece Catherine Barton (1679-1739). She and her husband, who lived with and kept house for Newton in his declining years, believed Newton’s story to be true. Another bit of evidence is Rev. William Stukeley’s (1687-1765) biography of Newton written in 1752. Stukeley, a physician, cleric and prominent antiquarian, wrote that he was once enjoying afternoon tea with Sir Isaac amid the Woolsthorpe apple trees when the mathematician reminisced that “he was just in the same situation as, when, formerly, the notion of gravitation came into his mind”.","PeriodicalId":87320,"journal":{"name":"Juniper online journal material science","volume":"127 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41247845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pioneering work of Yamada [1] and Fung [2] illustrated how difficult this goal would be since the behavior of human extracellular matrix (ECM) depends on strain-rate, Poisson’s ratio, direction of testing and is time-dependent [3]. A variety of methods have been used to evaluate the mechanical properties of tissues over the last 40 years including uniaxial and biaxial tensile testing, indentation and rotational tests, ultrasound elastography (UE), optical cohesion tomography (OCT), optical cohesion elastography (OCE), and vibrational analysis combined with OCT [4-6]. Many of these techniques require the assumptions that the material is linearly elastic, Poisson’s ratio is close to 0.5 and that viscoelasticity does not dramatically affect the resulting properties. However, the behavior of most tissues is that of a non-linear viscoelastic material that has upward curvature to the stress-strain curve. These concerns makes determination of the stiffness (tangent to the stress-strain curve) and other mechanical properties very difficult to quantitatively analyze since the tangent to the stress-strain curve is constantly changing [3,5,6]. However, despite all of these problems, there is a need to be able to characterize the mechanical properties of tissues and implants, since this would give researchers valuable information about the properties of tissues and implants used as medical devices. In this paper, we will discuss the use of vibrational optical coherence tomography to determine the quasi-elastic modulus of implants and tissues.","PeriodicalId":87320,"journal":{"name":"Juniper online journal material science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47303206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among toxic materials, although mercury and lead are the most toxic, arsenic and fluorine are also toxic. Especially, pollution of underground water by arsenic in Bangladesh and India is well known. Although mercury and lead exist as cationic species in aquatic environments, majority of toxic inorganic materials exist as anionic species. For example, arsenic (III and V) exists oxo-anions such as arsenite (AsO3) and arsenate (AsO4), respectively. To avoid the pollution by these toxic elements, severe standards are required for effluents from industries in each country. For example, the typical standards in Japan are as follows; chromium (VI): 0.5, selenium: 0.1, arsenic: 0.1, flourine: 8 (unit; mg/dm3). To clear these standards, various techniques have been developed to date and some of them have been commercialized. The typical techniques are precipitation, electrochemical treatments, Donnan dialysis, ion exchange and adsorption. However, these conventional techniques are suffering from some drawbacks such as poor selectivity, high operation costs and so forth.","PeriodicalId":87320,"journal":{"name":"Juniper online journal material science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46169108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
