Abstract: The application that is technically innovated from a three phase electrical knives change over switch was achieved electrical technical understanding of the device and the knowledge of connectivity. Two electrical sources are involved, the mains and the generator supply. The manual switching part of the generator was made use of by extending the cables meant for the switch. Three main ends of terminals are now involved, two wires from the generator switch, three wires from the generator output and three wires from the mains output. Interconnectivity of these terminals were put in place so that the manual switching, power supply from the mains and power supply from the generator were done to effect the functions, which are to put off the working generator as soon as the power is changed over. This set up has only saved the stress of going round to put off working generator.

Abstract: This paper presents a partial differential equation that determines Put option prices using both analytic formula and Crank-Nicolson numerical solutions for different stock prices. The deviation values were derived from Black-Scholes analytical solutions, placing certain criteria using three standard statistical tools as a measure for pricing effects. Results obtained revealed when options are overpriced, underpriced as well as no-mispricing which is in line with hypothetical predictions and important improvement over earlier efforts. In the same setting, Kolmogorov-Smirnov (KS) was used to verify the distributions of Black-Scholes (BS) and Crank-Nicolson (CN). In addition, the initial stock prices of no-mispricing were compared with others and results obtained indicated that initial stock price of forty (40) were the most significant and excellent stock price for Put options. This paper presented here has deep connotation for future studies of Put options. Consequently, our novel research contribution is unique and is strongly recommended for use in this area of mathematical finance.

D.H. Lawrence: A Study Of The Novels (The Plumed Serpent)

Abstract: The Plumed Serpent is a product of the author’s long-standing fascination for the American continent. It has its place in Lawrence’s ongoing quest for fullness in life: “I believe in America one can catch up some kind of emotional impetus from the aboriginal Indian and from the aboriginal air and land, that will carry one over this crisis of the world’s soul depression, into a new epoch.” Though, at times, he revolted against the Indian and later came to see the “hero” as “obsolete”, till some time after writing the novel, Lawrence considered The Plumed Serpent his “chief novel so far” which lay “nearer” his “heart than any other work” of his.¹¹ The shortcomings pointed out by critics and Lawrence’s own moments of repudiation for the American continent, the “acceptance-rejection ambivalence”¹² should not prevent one from seeing that the attempt, as ever, is to offer clues for better, healthy living, to take life to altogether more vivid circles of being.

Abstract: After the split of Arya Samaj, the first Gurukula was established in 1902 at Hardwar. After some time, the Gurukula movement soon grew very popular in the Haryana and a number of other such institutions came to be established in different parts of Haryana in the first half of the 20^th century. In 1909 a branch of the Gurukula was founded at Multan. Education imparted here was upto the school level only. The colonial government did not care much for providing educational facilities to the people of Haryana until 1880's. There were various reasons for this

从文小刚声子模型类比研究引力子----四川宽窄科学研究之16

Recommended: 王德奎 (Wang Dekui), y-tx@163.com

Abstract摘要：文小刚教授的书虽不是为了抛出“引力子”和引力场的“一元多体”，但他却提供了比希格斯提出“希格斯玻色子场”与引力场起源有关更多联系超引力的数学。如书中第3章第3.3.4节《波也是粒子》和第3.3.5节《超流体的玩具宇宙》，短短不足4000字却意味深长，可以再写出一本《量子多体理论----从声子起源到引力子、光子和电子起源》，直至研制出“量子引力信息隐形传输智能手机”。因为他统一了从无到有的时空一元多体与数学上的0、实数（正、负实数）、虚数（正、负虚数）等的应对。

Abstract: Valian family possessed a pedigree which is subject of debate because of its content and author. The name of Mohammad Jafar ibn Mohammad Ali Nasabeh appears At the bottom of pedigree. He was a genealogist of Qajar Era. The preparation date of this pedigree was written on the bottom as 1245 AH. It was during Hassan Khan reign who was Vali at the time till 1255 AH. Hussein Khan had ruled Poshtkooh for 30 years when pedigree was prepared. Mohammad Jafar Nasabeh noted on the pedigree that the original one was in the verge of destruction when he wrote the new one. The present research titled the history of Vali in west of Iran, investigated social and economic structure of Vali period and also their background and history. The research method in the present study is descriptive and data were collected by librarian method. The data of the present research were extracted from valuabe surces such as books, papers, Internet and so on. The findings of the present research indicated that The government of Lorestan satraps was continuous to early of Qajar government. Fathalishah Qajar after fixing his government in the country, appointed his son Mohammad Ali as satrap of western areas of Iran. During 1908, the son of Gholamreza Khan, Yadollah Khan was confirmed by king. During first regimen of Pahlavi (1907), Aligholi Khan the son of Gholam reza Khan that was satrap of Postkooh, after escaping of his father went to Baghdad and made a riot against Rezah Shah that was removed by Razmara.

Abstract: This study examined the effect of tramp shipping on container terminal performance of Apapa and Onne ports, Nigeria. Tramp shipping served as the independent variable or predictor variable. Also, container terminal performance served as the key dependent variable or criterion variable under which the measures such as cargo throughputs and vessel turnaround time have been appraised. The population of the study consisted of the staff in the two ports (Apapa,636 and Onne, 277), that is 913 staff and the study sampled 279 respondents out of which 222 of them were found useful and valid for the study analysis. The study collected data with the help of a structured questionnaire. The study used Pearson Products Moment Correlation Coefficient (r) to test the hypotheses with the aid of SPSS 22.0. The reliability of the research instrument was tested using the Cronbach alpha to ascertain the reliability of the instrument. The study found that tramp is a veritable platform for effective shipping operations. Conclusively tramp shipping has a positive and significant relationship with cargo throughputs of Apapa and Onne Ports and tram shipping has a positive and significant relationship with vessel turnaround time of Apapa and Onne Ports. Therefore, the study recommends that port operators’ performance should be appraised constantly in order to ensure that the maritime sector is positioned to achieve the stakeholders’ objectives in Nigerian ports.
