Physical and Emotional Impacts of Paternal Absence on Young Men in College
No full textLiterature regarding paternal absence infers that young men who experienced childhood are a great risk. Paternal Absence has additionally been connected to various personal issues, such as, substance abuse (Bryson, 2010), psychological distress(, and emotional instability. However, research under-stresses the defensive components that distinguish the ones who resist, or conquer the effects of paternal absence from the individuals who experience the impacts of its risk elements
Predicting Educational Relevance For an Efficient Classification of Talent
No full textThis research work utilizes machine learning approach to build a predictive model for the prediction of the students and the job seekers’ to quantify their fitness's for the courses and jobs they plan to pursue, respectively. Some of the existing research utilizes GPA for academic prediction and use personality prediction and computing in social domains for various industrial goals. On the other hand, this research work advances the state of the art to correlate and blend the personality features with the academic attributes to identify and classify the relevant talent of the individuals for the academic and real world success with improved predictive modeling. This work incorporates three algorithms to quantify a talent in the relevance, and then predict good fit students and good fit candidates, based on supervised learning, stochastic probability distribution and classification rules, etc. This work opens many opportunities for future research towards Genomics data mining to mine individuals for various areas
FPGA based Directional control of MTB cells For Bioengineering Applications
No full textWe designed a circuit using the logic elements of FPGA for controlling MTB. The circuit is connected to a mesh of coil, where a path of magnetic field is created using FPGA. The MTB’s motility is controlled in a particular direction along this path. Then the bacterial invasion is studied highlighting how the MTB cells and mutant cells interact using the FPGA based controller

Graphene Patterned Microchip For Colorectal Cancer Detection
No full textCancer currently stands as the second-leading cause of death worldwide. Studies reveal colorectal cancer (CRC) to be the 4th leading cause of mortality due to cancer. It is estimated that about 30% of CRC cases are hereditary, of which 5% are attributed by known syndromes, particularly Lynch Syndrome. Lynch Syndrome (LS) is caused by loss or malfunction of proteins responsible for DNA mismatch repair proteins (MMR), mostly MLH1 and MSH2, causing increased risks of developing CRC. Despite the small percentage accounted with the disease, the severity of the illness still remains immense since 80% of these patients eventually develop CRC and an overwhelming 40-60 % of female patients develop endometrial cancer, the major form of cancer in women in the developing nations. This pilot study aims to fabricate a DNA-graphene-polypyrole (DGP) based biosensor to diagnose deficiency of functional MMR proteins present in patients at a scale of less than ng/ ml. Fundamental understanding of interactions at the interface of biological molecules, such as proteins, and nanomaterials is therefore crucial for developing such biocompatible hybrid materials and biosensing platforms. Conductive nanomaterials-based biosensors offer the advantage of higher sensitivity and reliable diagnosis mainly due to their superior specific surface area and ballistic conductivity. Such films that immobilize proteins can synergize the properties of transducers and molecular recognition elements in order to improve biosensor performance and diversity. Here we report for the first time, the interactions between avidin and a graphene surface, which is being developed as a sensing platform for early detection of DNA mismatch repair proteins. We find that the interactive forces between avidin and graphene are mainly hydrophobic, along with some van der Waals, electrostatic and hydrogen bonding interactions. Notably, the structure and function of the avidin molecule is preserved after its adsorption on the graphene surface. Scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS) analysis of avidin immobilized on a graphenated polypyrrole (G-PPy) conductive substrate, confirms adsorption of avidin on graphene nanoplatelets and corresponding changes in electrical impedance, respectively. EIS analysis of MutS substrate and MutS immobilized on GPPy chips confirmed the working of the bio sensor by corresponding change in electrical impedance

Temperature Controlled 3D Bio-printing Using Bio-polymeric Ink
No full textBio-Printing 3D organs, tissues & scaffolds is advancing everyday, with various methods being introduces to mimic a perfect working organ or tissue which can be functional at the same time. We have developed a method to print bio-polymer in liquid state using them as bio-inks to prints scaffolds, while maintaining their temperatures. The design is cheap and efficient to print 3d scaffolds. Our Bio-Printer is also aided with a robotic arm to induce any bio-active ingredient in the 3d structures once it is printed without deforming or altering the structure of the scaffold. The main printer can be paused to allow the robotic arm to continue embedding and make repairs to the scaffold from any angle
Declines in marathon performance: Sex differences in elite and recreational athletes
No full textThe first aim of this study was to determine the age group at which marathon performance declines in top male and female runners and to compare that to the runners of average ability. Another aim of this of this study was to examine the age-related yearly decline in marathon performance between age group winners and the average marathon finisher. Data from the New York (NYC), Boston, and Chicago marathons from 2001–2016 were analyzed. Age, sex, and location were used in multiple linear regression models to determine the rate of decline in marathon times. Winners of each age group were assessed in 5-year increments from 16 through 74 years old (n = 47 per age group). The fastest times were between 25–34 years old, with overall champion males at 28.3 years old, and overall champion females at 30.8 years old (p = 0.004). At 35 years of age up to 74 years of age, female age group winners had a faster yearly decline in marathon finishing times compared to male age group winners, irrespective of marathon location [women = (min:sec) 2:33 per year, n = 336; men = 2:06 per year, n = 373, p < 0.01]. The median times between each age group only slowed beginning at 50 years old, thereafter the decline was similar between both men and women (women = 2:36, n = 140; men = 2:57, n = 150, p = 0.11). The median times were fastest at Boston and similar between Chicago and NYC. In conclusion, the rate of decline at 35 years old up to 74 years old is roughly linear (adjusted r2 = 0.88, p < 0.001) with female age group winners demonstrating 27 s per year greater decline per year compared to male age group winners.https://doi.org/10.1371/journal.pone.017212
Making Waves: Recent Developments of the South China Sea Disputes
No full textThe rocks of the South China Sea (SCS) are where state sovereignty and geopolitics converge. As observed by many, sovereignty disputes in the SCS entail more than simply who owns what particular geologic and geographic features. They involve shifting rights, shipping lanes, oil and natural gas reserves, the maritime environment, and security. These contested maritime zones have led to significant tensions in the region and raise great concerns for nations using the shipping lanes for international trade. These quarrels are also linked to rising nationalism in every claimant nation. At dispute are both ownership of land features and what rules to apply in resolving the disputes, since rules determine results. Continued tensions have restrained policies among the nations involved, making interactions difficult at times. To further complicate matters, nations have started to reclaim land to expand their control at the expense of others. To more vividly demonstrate how dynamic the “status quo” in the SCS is, this paper surveys the latest developments in the region; analyzes different attitudes and responses of various capitals to actions in the SCS in recent years. Competing interests are investigated to gauge each claimant’s strategies. The complexity of the overlapping claims involved calls for dialogue toward a peaceful diplomatic solution
