AbstractWe study the dynamics of real asteroids at the 2/1 resonance with Jupiter, and find that Griqua-like objects have a short life-time inside the resonance, while Zhongguo group can survive for many 108yr.

Frekuensi terbanyak indeks lingkar lengang atas per umur adalah 70%-85% (80%). Simpulan dari hasil penelitian status gizi anak talasemia β mayor adalah gizi kurang.Kata kunci: Status gizi, talasemia β mayorAbstract Thalassemia is a chronic disease who needs blood tranfusion every month because the abnormal erythrocyte has short life time compared with the normal erythrocyte. There are so many complications and effects of this disease, such as growth and nutritional status. The aim of this research is to describe chlidren's nutritional status with thalassemia beta major. This research is a descriptive research. It has been done since February 2012 - March 2013 at RSUP Dr.  M. Djamil Padang. The sampling is children with thalassemia beta major. The examination are stature, weight, and upper arm circumference and the result is entered into NHCS percentil and assessment of Nutritional based on health department of Indonesia. From this research, there are 15 children who are suffering thalassemia betamajor, and most of them is about 5-10 years old. The highest insident of stature per age index is 70-90% (60%). The highest insident of weight per age index is 60%-80% (66,7%). The highest insident of upper arm circumference per age is 70%-85% (80%).The conclusion of this research that the nutritional status children with thalassemia beta major is low nutrional.Keywords: nutritional status, thalassemia beta major

Comprehensive Framework

In recent years, crowd funding has seriously been considered as a novel method of financing start-up businesses and innovative ideas. In its short life time so far, the method has significantly grown in different aspects such as the number of proposed platforms, the number of campaigns and their success rate, the amount of capital provided, and the number of proposed models. In addition, various researchers have investigated the phenomenon from different points of view. Nevertheless, just a few studies have carried out a comprehensive review of the factors affecting this method. The main purpose of this research is to design and implement a comprehensive framework for factors that affect crowd funding. In order to achieve this goal, the effective factors in this regard were first identified through systematic review of the literature on crowd funding. Then, they were classified and clustered in a hexagonal framework based on the stakeholder's model. In other words, a qualitative method is used to extract the factors affecting crowd funding. The hexagons extracted from the literature were in 82 clusters out of which 38 were accounted for by capital seekers, 16 by investors and platforms, and 12 by other stakeholders. This study is the first effort to design a comprehensive framework for factors that affect crowd funding. Doi: 10.28991/HIJ-2021-02-02-07 Full Text: PDF

Time Restriction

The reporting period has shown that Space has become a firmly established domain in observational Astrophysics, also in the low energy astrophysics area. The launching of new spacecraft is always an important addition to the capabilities of the Astronomers, but the availability of space observatories is strongly affected by the fact that they disappear as their subsystems become damaged or, for other reasons, become inoperable. The relatively short life of astronomical space facilities has generated new dynamic in the life cycle of observational tools for the astronomer, rather different from that for ground facilities. Launch failures or the final in-orbit functionality verification can also very strongly affect the availability of observational capabilities in space astrophysics. The only spacecraft designed without this built-in life time restriction, is the Hubble Space Telescope, which can be serviced by the Space Shuttle.

The paper considers the possibility of EAS production by charmed particles and direct muons (muons produced in decays of particles with a very short life-time comparing to that of charmed particles, as, for example, in decays of resonances). At large angles (≳ 70°) charmed particles and direct muons could be completely responsible for EAS measured at the sea level. The estimations are made for the primary nucleon energy 1019 eV and the angles 45–72°.

It is shown that the cycling rate in the optimum tritium concentration in μCF and in the n=2, J=1, ν=0 state is 2.35 times higher than in n=1, J=ν=0 state. The methods to explore forced μCF of the n=2 state is discussed. Although the n=2 state shows to be more efficient in terms of its cycling rate, all suggested drivers seems to be useless with respect to the input energy requirement and short life-time of resonance states. It is shown that even using x-ray sources as a driver, and designing hybrid system, the suggested forced hybrid system energy gain is 13 and very good gain enhancement but still is far away to be of interest for practical applications with respect to very short life-time of resonance states.
