Effect of Chemical Treatment on the Tensile Properties of Single Oil Palm Empty Fruit Bunch (OPEFB) Fibre_ Crimson Publishers

Effect of Chemical Treatment on the Tensile Properties of Single Oil Palm Empty Fruit Bunch (OPEFB) Fibre by Hassan CS* in Trends in Textile Engineering & Fashion Technology_ Textile Science Engineering Journal

 

Abstract

A study on effect of chemical treatment on the tensile modulus and strength of single oil palm empty fruit bunch (OPEFB) fibre is presented in this paper. The fibres were treated with alkaline treatment using sodium hydroxide of 5% concentration. Tensile test were conducted in accordance to the ASTM C1557. Results revealed that the tensile modulus of the treated fibres decreases by around 55% as compared to the untreated fibres. Tensile strength on the other hand increases by around 25% with the alkaline treatment. The tensile strength was found to be dependent on the fibre diameter where the strength decreases with the increases in fiber diameter at fracture. SEM revealed higher porosity at larger fibre diameter which contributed to the degradation of the fibre tensile strength. No significant impact by the alkaline treatment was observed to the tensile strain of the fibre

It Has Been Half a Century Since President Nixon Declared War on Cancer: Destabilization of Abnormal Methylation Enzymes Has the Blessing of the Nature to Win the War on Cancer_ Crimson Publishers

 It Has Been Half a Century Since President Nixon Declared War on Cancer: Destabilization of Abnormal Methylation Enzymes Has the Blessing of the Nature to Win the War on Cancer by Ming C Liau,* in Advances in Complementary & Alternative medicine_ journal of alternative medicine research

 

Abstract
President Nixon declared war on cancer in 1971. When a president of the USA declares a presidential project, he has the determination to achieve the goal in 5 years. There were two precedents: the Manhattan Project of President Roosevelt and the Apollo Project of President Kennedy. In both precedents, nuclear physicists and rocket engineers were successful to achieve the presidential project within 5 years. Health profession failed the challenge during the 5 years of intensive presidential support, and in the following 44 years of earnest public expectation. Is it so difficult to put cancer away? Yes, as we have pointed out previously [1], that in theory it was not possible to solve cancer with conventional cell killing strategies, because cancer stem cells (CSCs) stood in the way. And no, there were other ways to get rid of CSCs and to solve problems confronting cancer

Use of Cover Crops in Organic Sweetpotato Production to Improve Yield: A Case Report_ Crimson Publishers

 Use of Cover Crops in Organic Sweetpotato Production to Improve Yield: A Case Report by Xi Xiong* in Modern Concepts & Developments in Agronomy_ International Journal of Agronomy

 

Abstract
Organic Sweetpotato (Ipomoea batatas (L.) Lam) production in the United States has become more popular due to consumers’ concern regarding food safety. Growers, however, are challenged by many issues in organic production, including weed control that was often cited as the number one factor contributing to yield reduction. This report described a case study conducted on an organic farm in central Missouri, USA where cereal rye (Secale cereale L.) or rapeseed (Brassica napus I.) were planted as cover crops. The two crops were terminated by either tilling a couple of times or mowing followed by crimping prior to Sweetpotato transplanting. This case study demonstrated that tilling the cover crops rather than mowing and crimping resulted in significant weed control especially in the early part of the growing season. This suppression also resulted in up to three times the root tuber production, compared to the untreated control where no cover crops were planted. Between the two crops, cereal rye appeared to produce a higher yield in terms of tuber counts. This case report suggests that tilling cover crops prior to Sweetpotato transplanting can benefit organic Sweetpotato production.

Characteristics of Sickle Cell Trait Policies and Procedures at NCAA Division II Institutions_ Crimson Publishers

Characteristics of Sickle Cell Trait Policies and Procedures at NCAA Division II Institutions by S Andrew C* in Research & Investigations in Sports Medicine_ Journal of Sports Medicine

 

Abstract
In 2010, the National Collegiate Athletic Association (NCAA) introduced a proposal addressing sickle cell trait (SCT) screening. This new proposal policy required all NCAA Division I student-athletes beginning their initial year of enrollment provide their institution with accurate information regarding their SCT status. Following the NCAA Division II creating this requirement, the NCAA Division II adopted the same requirement. In addition to these screening requirements, the National Athletic Trainers’ Association (NATA) released a statement recommending institutions utilized education on SCT as a method of preventing SCT related injury. To the author’s knowledge, there does not appear to be a study conducted in recent years to assess how many institutions are following the NCAA and NATA’s recommendations on SCT screening. Therefore, the purpose of this study is to describe the basic characteristics of SCT policies and procedures at NCAA Division II institutions. 73 NCAA Division II head athletic trainers participated in this study. Participants were sent an electronic survey via email that assessed availability sickle cell trait testing, availability of sickle cell trait waivers, and policy and procedure revision processes. Data was downloaded and analyzed using a commercially available statistics package (SPSS Version 26, IBM, Armonk, NY). The majority of head athletic trainers reported that their institution required SCT testing for their student-athletes (n= 40, 54.8%). 62 institutions reported offering SCT testing to their student-athletes either at the institution’s or the student-athlete’s expense. However, only a slight majority of institutions provided their student-athlete population with yearly education on SCT (n= 41, 56.2%). On average, institutions and team physicians reviewed SCT policies and procedures on an annual basis. 19.2% (n=14) of institutions had not reviewed their policy in the past two years, and 15.1% (n=11) of institutions did not have polices that had been reviewed by their team physician in the past two years. While the majority of responding institutions appeared to be at least minimally compliant with SCT screening procedures, athletic training staff and institutions should be encouraged to conduct annual reviews of the SCT screening policies and procedures. Institutions should consider implementing annual sickle cell trait education for student-athletes.
