Model Tikus Omenn Syndrome

In 1965, Gilbert Omenn described a rare, inherited disorder which produced paradoxical combination of immunodeficiency and immune dysregulation. The term Omenn Syndrome was coined originating from this report. More than 40 years ago since it first described, the pathogenesis of OS has remained mysterious and these could be due to unavailable animal model for OS yet. This paper evaluates and discusses 2 murine models of OS that have been found and developed recently by 2 research groups from Japan and Italia. These two murine models bearing mutation in the V(D)J recombination analogous to those causing human OS. These two mouse models have been recapitulate the disease and provide insight into the pathogenesis of OS and also it relation with immunodeficiency combined with autoimmunity and atopy in OS and other related diseases

Finite element analysis of chip formation in grooved tool metal cutting

Machining simulations of orthogonal cutting are performed using the finite element method to predict chip formation in grooved tool cutting. A flat-faced cutting tool is first simulated to check the validity of the model, and the results obtained are used as a basis for comparison in grooved tool cutting simulation. Grooved tool simulations are modeled next to investigate the effect of a groove on the chip formation process. Groove depth and width were the two parameters changed for the purpose of analyzing the chip flow characteristics, stress and strain distributions found in the chip.;For all simulated cases, it is observed that a groove definitely impart more curl on the chip, and more tensile and/or compressive near the chip root, a condition conducive to chip breaking. More curling is observed when the groove radius of curvature is reduced by increasing the groove depth or decreasing the groove width. It is also observed that the increase in normal tensile stress at the chip root next to the tool tip is proportional to the amount of curl displayed in the chip. However, the increase in normal compressive stress is related to the increase in chip thickness, a variable that depends on the effective rake angle of cutting

Elucidation of chemical reaction networks through genetic algorithm

PhD ThesisObtaining chemical reaction network experimentally is a time consuming and expensive method. It requires a lot of specialised equipment and expertise in order to achieve concrete results. Using data mining method on available quantitative information such as concentration data of chemical species can help build the chemical reaction network faster, cheaper and with less expertise. The aim of this work is to design an automated system to determine the chemical reaction network (CRN) from the concentration data of participating chemical species in an isothermal chemical batch reactor. Evolutionary algorithm ability to evolve optimum results for a non-linear problem is chosen as the method to go forward. Genetic algorithm’s simplicity is modified such that it can be used to model the CRN with just integers. The developed automated system has shown it can elucidate the CRN of two fictitious CRNs requiring only a few a priori information such as initial chemical species concentration and molecular weight of chemical species. Robustness of the automated system is tested multiple times with different level of noise in system and introduction of unmeasured chemical species and uninvolved chemical species. The automated system is also tested against an experimental data from the reaction of trimethyl orthoacetate and allyl alcohol which had shown mixed results. This had prompted for the inclusion of NSGA-II algorithm in the automated system to increase its ability to discover multiple reactions. At the end of the work, a final form of the automated system is presented which can process datasets from different initial conditions and different operating temperature which shows a good performance in elucidating the CRNs. It is concluded that automated system is susceptible to ‘overfitting’ where it designs its CRN structure to fit the measured chemical species but with enough variation in the data, it had shown it is capable of elucidating the true CRN even in the presence of unmeasured chemical species, noise and unrelated chemical species

坤甸圣父初中学校二年级学生对近义词 “多少“与 “几” 的掌握情况分析

AbstractSynonyms refer to a group of words with basic but slightly different rational meanings. "How many" and "How much" are both synonyms. Both "how many" and "How much" are interrogative pronouns used to ask about quantity. The word "how many" can be used without the quantifier, while the word "ji" must be used with the quantifier. These two words are commonly used in daily life. They have similarities and differences in meaning and usage. Therefore, Chinese learners often misuse these two words early. In order to understand the situation and difficulties of the second-year students of Pontianak Father’s junior high school on the synonymous words "how many" and "How much", the author uses a test method to test the students. The test results show that students have a better grasp of the synonymous word "how many" than "How much". The correct rate of "How much" reached 68.03% and the correct rate of "how many" reached 64.33%. Analyzing the difficulty, the author finds that the student author finds that some students still don’t understand the difference between using "how many" and "how much."Keywords: Synonym Word “How many” and “How much” Condition of Master
