FREKUENSI POSITIVITAS ANTIBODI TERHADAP HELICOBACTER PYLORI PADA KELOMPOK DONOR DARAH DI SURAKARTA
J. B. Suparyatmo
Bulletin of Health Research , 2012,
Abstract: The patho-physiology of the gastritis achieved a significant progress in 1983, when it was proven that Helicobacter pylori colonized in the gastric mucosa. Several studies confirmed the relationship between Helicobacter pylori (H. pylori) and the type B gastritis. Further study reported the evidence of H. pylori colonization in the gastric anthrum of almost all duodenal ulcer patients. Since this micro-organism infected almost all subjects through out all ages, epidemiological data was therefore very important to determine the strategy to control the disease. This study aims to obtain the prevalence of the positivity of the antibody against. H. pylori (anti-Hp) among the volunteer blood donors in Surakarta. The passive haemagglutination (PHA) method (Biomedik-Mataram) was carried out to test the anti-Hp among 511 healthy subjects. The results obtained were 1984 (36%) showed anti-Hp positive. There is no significant difference between male and female groups in this study (p>0.05). The results of this study can be used as a preliminary study for further research to complete the epidemiological data of the H. pylori infectivity in Surakarta.
ASTER DEM Based Studies for Geological Investigation around Singhbhum Shear Zone (SSZ) in Jharkhand, India  [PDF]
B. SINGH, J. DOWERAH
Journal of Geographic Information System (JGIS) , 2010, DOI: 10.4236/jgis.2010.21003
Abstract: Singhbhum Shear Zone (SSZ) is a geologically rich belt with structures like faults and folds being the distinctive features. Due to these characteristics this area has been an important centre of studies since past few decades. With the advent of Remote Sensing and GIS, it has been possible to study and interprete geological setting of any area in the laboratory itself without even visiting the field again and again. The present study aims to investigate the geology of the SSZ from ASTER DEM by observing the elevation, as-pect, texture, pattern etc of shaded relief images. This can prove to be an excellent supplementary information database for interpretations along with other data.
Curbing Bullying  [PDF]
J. B. Moores
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.812128
Abstract: “On April 20, 1999, the corridors and classrooms of Columbine High School in Littleton, Colorado, reverberated with the sound of gunshots. Two students, armed with assault weapons and explosives, had gone on a rampage, killing a teacher and several of their fellow students. They then turned their guns on themselves.” (p. 373) Bullying is epidemic and no longer can be ignored! Within this commentary article, there is a research that has been performed in Norway by Psychologist Dan Olweus that improved the bullying program. One method suggested that a potential key for improvement to the bullying program, if implemented robustly, includes: seeing, thinking, and doing social skills. Another method would consist of having all parties within the public school system be involved and work together to help stop unwanted aggressive behavior. This could involve identifying the problem and educating school staff as well as parents on bullying. Next, develop a program, as Dr. Olweus has described in his approach. Finally, implement the program. Dr. Olweus’ results noted a decrease in bullying by half in every grade level. The purpose of this article is to help the school systems either improve any anti-bullying program that is already implemented or help to guide and discuss a successful program if none currently exists. Unfortunately, bullying will most likely always exist, just as many kinds of discrimination exist. However, there may be other benefits for children who learn social skills positively. For example, having deeper levels of empathy, learning to have a communal relationship versus exchange relationship, or being a more romantic partner. Moreover, if bullying decreases within the public school system, then children may miss less school and obtain a quality education.
Thoughts on Addiction Prevention  [PDF]
J. B. Moores
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.101007
Abstract: All drugs of addiction produce a positive reward with efficacy and once the efficacy tapers off so do the effects from the drug. Despite the consequences that can occur from an addicting behavior, individuals like how the reward made them feel. Therefore, repeating the behavior over and over creates a cycle of addiction. Equally important, is the social concern from the mortality rate statistics from drug addiction listed from most to least overdose: opioid, cocaine, and benzodiazepines. According to the Centers for Disease Control and Prevention statistics and in Figure 1. “More than 72,000 Americans died from drug overdose in 2017; 49,068 involve opioid overdose, 14,556 involve cocaine overdose; and 10,684 involve benzodiazepine overdose” (National Institute on Drug Abuse, 2018). Within this commentary article, there will be suggestive research for an optimistic outlook on novel ways to approach our nation’s crisis. In addition, there will be some examples of the most common prescription drug types describing their mechanism of action. Finally, discussing the stages of drug addiction to reveal where relapse occurs so there can be better monitoring and documentation while help aiding with some of the Health and Human Services 5-Point Strategy, “Better addition prevention, treatment, and recovery services, better data, better pain management, better targeting of overdose reversing drugs, and better research” (U.S. Department of Health and Human Services, 2018).
Correlation between Hardness, Structure and Electrochemical Performance of an AlZnMnMg Alloy  [PDF]
S. Valdez, B. Campillo, J. J. Islas
Engineering (ENG) , 2012, DOI: 10.4236/eng.2012.49075
Abstract: In this work the structural changes induced by aged treatment have shown a connection with differences of hardness and electrochemical performance. Al-base alloys have been investigated by means of Vickers hardness, X-ray diffraction, scanning electron and short-term electrochemical test. X-ray diffraction result reveals the formation of (MgZn)49Al32 phase for two conditions, the first one is when the magnesium content is upper to 5.49% in as-cast condition and the second one after the thermal treatment carried out at 450?C for 5 h. In addition, the hardness and electrochemical performance has been influenced by the presence and quantity of the (MgZn)49Al32 phase. The addition of magnesium alloying modifies the microstructure, increases the content of (MgZn)49Al32 phase and provides a localized corrosion which conduced to the breakdown of the oxide film (?-Al2O3) formed on the Al alloy surface.

Ethnic Diversity as Tool of Good Governance in Nigerian Political Dialectics  [PDF]
Chika J. B. Gabriel Okpalike
Open Journal of Social Sciences (JSS) , 2015, DOI: 10.4236/jss.2015.36021
Abstract: The principles of Good Governance presume peoples, nations, systems, corporations, cultures and so forth. These entities are what must be found at the backdrop of a possible Good Governance in Nigeria. Meanwhile the collapse of any civilization; the decay of any society; the death of the human spirit in any epoch is often heralded by the deterioration of culture. In other words anarchy in and disintegration of any society are consequent upon a decline, decadence, misconstrue or neglect in the culture of that society. Identifying the veritable Nigerian culture is a task outside whose accomplishment Good Governance in the country remains a farce, because it is a people who generate culture and a culture which grounds Good Governance. The quest for Good Governance in Nigeria is a pipe dream; a flight of fancy in as much as the Nigerian people is phantom and their culture inanity. Meanwhile it is more convenient to talk about the people, culture, language and religion of Nigeria in plural terms. Therefore we can only say Nigerian cultures, languages and religions. It was John S. Mbiti [1] and Emefie I. Metuh [2] who had agreed on this plurality only in terms of African Religions. Plurality as diversity is the essential character of Nigeria. We may conveniently talk about the Igbo (Likewise Yoruba, Hausa, Kalabari, Ogoni, Ibibio, Tiv and so on) culture, language, religion, people and so forth. Yet even at that, what we mean can easily identify with the past and dying ways of the people which the present recalls according to the strength of their hindsight, but which has no relevance at all on the life of those who commemorate them. This article from a phenomenological perspective understands culture as a unified way of life that binds a people together and identifies its absent presence in Nigeria with the inevitable consequence of the illusiveness of Good Governance. It then opens the vistas of another possibility of building Good Governance on the same diversity.
Improved Automotive CAN Protocol Based on Payload Reduction and Selective Bit Stuffing  [PDF]
B. Vinodh Kumar, J. Ramesh
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.710291
Abstract: In this research paper, the implementation strategies of automotive controller area network protocol are investigated and the short messaging scheme with selective bit stuffing method to improve the effective utilization of its bandwidth has been proposed. There would be a sharp decrease in the performance of traditional CAN protocol because of considerable increase in the number of ECUs (Electronic Control Units) and infotainment gadgets connected in the vehicle architecture. The demand for safety, emission, diagnostics and comfort norms has steeply increased the number of messages in the 250 Kbps CAN network as the computational power of ECUs has gone up. To overcome this problem, the short CAN method has been proposed and the work is benchmarked with SAEJ1939 Heavy commercial vehicle CAN standard. The Matlab Simulink based short CAN has been modeled and the performance of the proposed system has evaluated using virtual instrument cluster. Experimental results have shown that compared to the traditional CAN, the proposed method has reduced the worst case response time of CAN extended frame from 160 μ sec to 144 μ sec. Selective bit stuffing technique has reduced the impact of bit stuffing over the payload and improved the utilization factor for the CAN bus without affecting the CAN message ID properties. The proposed algorithm has been modeled and simulated using CAN Matlab model Simulink and it has been verified using virtual CAN tool and real time CAN bus hardware.
Continuum Lowering -- A New Perspective
B. J. B. Crowley
Physics , 2013, DOI: 10.1016/j.hedp.2014.04.003
Abstract: What is meant by continuum lowering and ionization potential depression (IPD) in a Coulomb system depends upon precisely what question is being asked. It is shown that equilibrium (equation-of-state) phenomena and non-equilibrium dynamical processes like photoionization are characterised by different values of the IPD. In the former, the ionization potential of an atom embedded in matter is the difference in the free energy of the many-body system between states of thermodynamic equilibrium differing by the ionization state of just one atom. Typically, this energy is less than that required to ionize the same atom in vacuo. Probably, the best known example of such an IPD is that of Stewart and Pyatt (SP). However, it is a common misconception that this formula should apply directly to the energy of a photon causing photoionization, since this is a local adiabatic process that occurs in the absence of a response from the surrounding plasma. To achieve the prescribed final equilibrium state, additional energy, in the form of heat and work, is transferred between the atom and its surroundings. This additional relaxation energy is sufficient to explain the discrepancy between recent spectroscopic measurements of IPD in dense plasmas and the predictions of the SP formula. This paper provides a detailed account of an analytical approach to calculating thermodynamic and spectroscopic (adiabatic) IPDs in multicomponent Coulomb systems of arbitrary coupling strength. The ramifications are carefully examined in order to elucidate the roles of the various IPD forms. A formulation in terms of free energy leads to an analytical equation of state (EoS) that is thermodynamically self-consistent, provided that the bound and free electrons are dynamically separable. Of the various proposed formulae, the Spectroscopic (adiabatic) IPD gives the most consistent agreement with spectroscopic measurements.
parameterrization of microphysical and dynamical processes of rainfall in thunderstorm cloud model
S. J.,J. B.
Iranian Journal of Physics Research , 2002,
Abstract: In this research parameterization of the precipitation process in Ogura & Takahashi (O-T) thunderstorm model was improved in microphysical processes, specially in the autoconversion process to form raindrops, in the glaciation process and in the terminal velocities of rain and hail. The rainfall intensity became much heavier with Kesslers parameterization, the second peak of the rainfall intensity disappeared with Biggs freezing probability, and the rainfall intensity became much heavier and sharper with Lin et als terminal velocities of rain and hail than in the O-T original model. Finally, the derived rainfall pattern based on the improved model has much similarities to the observation data. This paper expresses the basic research for studying the physical treatment in clouds. The modified O-T model has different applications in analyzing radar observation data, estimate the potential of soil erosion, parameteriztion of shower in mesoscale numerical weather prediction and eta.
