Why Does Newton’s Apple Fall Vertically to the Ground: The Gravitation Code

Author(s): Jean-Paul Auffray

ABSTRACT
No, Isaac Newton did not “explain” gravitation. What he did, and this certainly constituted all and by itself a great achievement, was to recognize (to “assert”) the universal character of gravitation: all material objects (bodies) attract each other by gravitation. But how does gravitation perform its deeds? This remained a mystery to Newton. In a “desperate move” at the end of his life, he introduced the concept of “Particles which are moved by certain active Principles [our emphasis]—such as is that of Gravity” he said. We resurrect this scheme, we provide it with a quantum structure—a stunning new insight into the workings of gravitation obtains.

Preparation and Quality Evaluation of Extended Beef Rounds Containing Gum Arabic from Acacia senegal var. kerensis

Author(s): Johnson K. Mwove1, Lilian A. Gogo, Ben N. Chikamai, Mary N. Omwamba, Symon M. Mahungu

ABSTRACT
It was of interest to determine the water holding effect of the gum from the Acacia senegal var. kerensis in extended beef rounds. Beef rounds injected at two injection levels (30% and 35% over green weight) with curing brines containing gum arabic at 1%, 1.5%, 2.0%, 2.5% and 3.0% of the final product were investigated. A non-injected sample and a product injected with soy protein concentrate (SPC) at 3.5% of the final product weight were prepared for comparison. Mean results indicated that the level of gum arabic from Acacia senegal var. kerensis used in curing brines significantly increased the cook yield and reduced the extractable moisture in cooked extended beef rounds. The injection of beef with curing brine also significantly increased the cook yield and the extractable moisture of the extended beef rounds as compared to the non-injected beef samples. Both injection and gum levels had a significant effect on the proximate composition and sensory properties of the resulting beef rounds. Sensory analysis (Food and Nutrition Sciences journal) revealed that samples containing gum arabic at 2.5% were juicier and comparable to those containing SPC at 3.5% injection level. Furthermore, these samples had the highest overall preference comparable to samples injected with curing brines containing SPC. This is the first report on the physicochemical properties of extended beef rounds containing gum arabic from Acacia senegal var. kerensis.

Factors Affecting Maternal Coping in Korean Mothers of Children with Cancer

Author(s): Shanzida Khatun, Hee Soon Kim, Hyun-Bong Park

ABSTRACT
Background: The childhood cancer is increasing throughout the world. The incidence of children and adolescent (1 – 19 years old) mortality by cancer was 4.49 by 2006 (Korea Statistics, 2014). Mothers of children experienced a difficult situation in coping when their children were diagnosed with cancer. Based on Mishel’s Uncertainty in Illness Theory, maternal uncertainty and perceived social support are important factors that may have an impact on maternal coping in mothers of children with cancer. Therefore, it was worth to investigate this phenomenon in the context of Korea where no such study was conducted. Continue reading

Author(s): Patricia Lupion Torres, Neusa Nogueira Fialho, Raquel Pasternak Glitz Kowalski, Alexandra Okada

ABSTRACT
This presented research has been developed in Curitiba, Brazil at Pontificia Universidade Catolica do Parana—PUCPR and has organized exhibition by the research group Pedagogical Practice on Teaching and Learning with Educational Technologies—PRAPETEC. This group has partnership with Engage Project that implements practices of Responsible Research and Innovation (RRI), equipping the next generation to participate in scientific issues to change how science is taught. In this context, the question to this investigation was as follows: how to explore the issues related to agricultural biodiversity, specifically to GM products in order to promote RRI? The subject of this study was to promote RRI practice on agricultural biodiversity, emphasis on GM products, in order to disseminate questions directed to this issue, through Facebook social network. This practice has national and international repercussions, with a range of diverse audience participation, involving teachers, students and in general the community from Brazil and other countries. The results show that there is still much to learn about GM products, particularly regards on the identification of these foods, which are genetically modified.

Modeling and Implementation of AC Electrical Capacitance Tomography

Author(s): K. Manikandan, S. Sathiyamoorthy

ABSTRACT
Electrical Capacitance Tomography (ECT) determines the dielectric permittivity of the interior object depending on the measurements of exterior capacitance. Generally, the electrodes are placed outside the PVC cylinder where the medium to be imaged is present; but in ECT using inter-electrode capacitance measurements can be achieved by placing inside of the dielectric medium. In the proposed ECT system, the ECT sensor is modeled using ANSYS software and the model is implemented in real ECT system. For each step of measurement, a stable AC signal is applied to a pair of electrodes that form a capacitor. The novel system is to measure the capacitance range variation in picofarad and the corresponding voltage ranges from 1 volt to 4 volts. The switching speed of all combinational electrodes is implemented using embedded system to achieve higher speed performance of AC ECT system which eliminates the drift and stray capacitance error. This is yielding the original image of unknown multiphase medium inside the electrodes using Lab VIEW. This paper investigates several advantages such as improved overall system performance; simple structure, avoids stray capacitance effect, reduces the drift problem and achieves high signal to noise ratio.

Halo Orbits around Sun-Earth L1 in Photogravitational Restricted Three-Body Problem with Oblateness of Smaller Primary

Author(s): Prithiviraj Chidambararaj, Ram Krishan Sharma

ABSTRACT
This paper deals with generation of halo orbits in the three-dimensional photogravitational restricted three-body problem, where the more massive primary is considered as the source of radiation and the smaller primary is an oblate spheroid with its equatorial plane coincident with the plane of motion. Both the terms due to oblateness of the smaller primary are considered. Numerical as well as analytical solutions are obtained around the Lagrangian point L1, which lies between the primaries, of the Sun-Earth system. A comparison with the real time flight data of SOHO mission is made. Inclusion of oblateness of the smaller primary can improve the accuracy. Due to the effect of radiation pressure and oblateness, the size and the orbital period of the halo orbit around L1 are found to increase.

How Does Objective Career Success Affect Subjective Career Success? The Moderating Role of Self-Awareness

Author(s): Qianni Gu, Yong Su

ABSTRACT
Studies on the relationship between objective career success and subjective career success are seldom in the career success research. In this study, we hypothesize a positive relationship between objective career success and subjective career success. Moreover, we conduct interview to find out the new indicators for measuring the subjective career success in Chinese context. Further, we come up with self-awareness as moderator. We hypothesize that people with high public self-awareness have strong relationship between objective career success and subjective career success; people with high private self-awareness have weak relationship between objective career success and subjective career success. However, the results are not entirely as expected. The public self-awareness has impact but the private self-awareness has no impact on this relationship.

Psychophysiological Effects of a Combination of Sideritis and Bacopa Extract (memoLoges®) in 32 Subjects Suffering from Mild Cognitive Impairment. A Double-Blind, Randomized, Placebo-Controlled, 2-Armed Study with Parallel Design

Author(s): Wilfried Dimpfel, Andreas Biller, Samir Suliman, Gwladys N. Chiegoua Dipah

ABSTRACT
Mild cognitive impairment (MCI) can be regarded as a non-demented transitional stage during the development of Alzheimer’s disease. Early recognition of this stage might increase the chance of prevention by early treatment. Within a pilot study, two plant-derived preparations and mixtures thereof were tested successfully in subjects suffering from MCI. A combination of Sideritis scardica and Bacopa monnieri extract (memoLoges®) was chosen now for a repetitive dosing during 4 weeks. Thirty-two subjects aged 50 to 80 years and suffering from MCI (having a DemTect questionnaire score between 8 and 13) were recruited for intake of 2 capsules of the preparation per day. Quantitative EEG recording during relaxation and concomitant performance of three 5 minutes lasting psychometric tests (d2-concentration test, arithmetic calculation test and memory test) was achieved at the first day and one day after the last repetitive intake.

Psychophysiological Effects of Zembrin®Using Quantitative EEG Source Density in Combination with Eye-Tracking in 60 Healthy Subjects. A Double-Blind, Randomized, Placebo-Controlled, 3-Armed Study with Parallel Design

Author(s): Wilfried Dimpfel1, Nigel Gericke2, Samir Suliman3, Gwladys N. Chiegoua Dipah3

 

ABSTRACT
The endemic South African succulent plant Sceletium tortuosum (L.) N.E. Br., family Mesembryathemaceae, is known as kanna in Nama, kougoed in Afrikaans, and sceletium in English. The plant has been used as a tea and as a masticatory for millennia by indigenous San hunter-gatherers and Nama pastoralists for endurance and well-being. It has been reported that the plant “gives strength to their limbs, and takes away pain, and makes their memory strong”. The current investigation aimed at the psychophysiological characterization of 25.0 and 50.0 mg of a special extract marketed as Zembrin® in comparison to placebo using a new methodology called “EnkephaloVision”. This combination of EEG Neurocode-Tracking and Eye-Tracking allows for concomitant analysis of time epochs of only 364 ms duration. Continue reading

Studying the Effect of Urban Furniture on Satisfaction of Domestic Tourists in Isfahan Bus Terminals

Author(s): Zahra Nadim, Mehri Azani

ABSTRACT
Terminals and stations as one of the most important parts of transportation systems and also as the arteries of the country’s economy life undertake significant role in adjustment and regulation of the traffic pulse of cities and roads. Urban furniture is one of the components considered in urban designing and as a part of the whole city, it defines the urban identity and structure. In today’s world, the importance of designing the urban equipment and furniture is to an extent that even active architects in the field of industrial designing are invited for designing and performing the urban furniture and equipment. Urban designing is a thing beyond making some flower box in squares and determining bus and taxi stations. Evidently, what gives identity to the city or according to the saying of “Sansovini”, what has tranquility for the city’s residents and creates attraction for foreigner tourists, not only includes the mass buildings and streets traffic, but also it includes landscape, parks and furniture of the city. Standard designing of bus terminals like other urban furniture influences on urban face and it can have significant role in satisfaction of domestic tourists and increase and propagation of using of terminals.
