The use of IT to increase nutritional awareness in young children
It has been well documented that obesity amongst young children is on the increase. By the age of 5 the levels of obesity is alarming and is much greater than expected in comparison to the national standards. To address this problem an overall health programme is required encompassing healthy eating and physical activity. However, a radical change of this nature has not shown any long-term benefits and can result in a negative attitude from the child. Therefore, more subtle ways of increasing awareness in children about healthy eating were thought to be the key. Since children are spending an increasing amount of their free time playing computer games it was thought that this would be a good way of introducing them to healthy eating. Therefore, a prototype system is developed and tested to identify whether IT can be used to raise nutritional awareness in young children. The results show that the increase is marginal but the system did encourage discussion about the effects of food amongst a group of children aged between 4-5
Hidden Extra U(1) at the Electroweak/TeV Scale
We propose a simple extension of the Standard Model (SM) by adding an extra
U(1) symmetry which is hidden from the SM sector. Such a hidden U(1) has not
been considered before, and its existence at the TeV scale can be explored at
the LHC. This hidden U(1) does not couple directly to the SM particles, and
couples only to new SU(2)_L singlet exotic quarks and singlet Higgs bosons, and
is broken at the TeV scale. The dominant signals at the high energy hadron
colliders are multi lepton and multi b-jet final states with or without missing
energy. We calculate the signal rates as well as the corresponding Standard
Model background for these final states. A very distinctive signal is 6 high
p_T b-jets in the final state with no missing energy. For a wide range of the
exotic quarks masses the signals are observable above the background at the
LHC.Comment: 19 pages, 5 figure
An Outbreak of Malaria in a Surgical Ward : Possibility of Mechanical Transmission
Penularan malaria pada umumnya terjadi melalui vektor yakni nyamuk Anopheles. Cara penularan lain adalah melalui transfusi darah atau secara congenital pada bayi yang baru lahir. Penularan secara mekanis misalnya melalui alat suntik sangat jarang dijumpai. Berikut ini disajikan laporan penelitian terhadap 26 penderita malaria Plasmodium falciparum yang terjadi antara periode November 1981 sampai dengan Maret 1982 di bangsal bedah pria Rumah Sakit Umum Hasan Sadikin, Bandung. Hipotesa penularan melalui alat suntik/semprit ditegakkan sesudah diadakan penyelidikan epidemiologik dan entomologik. Ternyata disposable syringe di bangsal perawatan tersebut digunakan untuk lebih dari satu penderita. Hipotesa diperkuat dengan tidak timbulnya lagi penderita setelah alat suntik hanya dipergunakan untuk satu orang penderita yang dirawat
Necessity of Particle size studies of Ores from Bihar by the Mineral Industry
The measurment of particle size of various minerals, specially of the friable ores, which are commonly
found in Bihar and the study of properties of material
as function of size have applications in several fields. Recently, the subject has attracted the attention of industrial researchers. In this paper the necessity of particle size studies of ores of Bihar as applicable in general to the mining and mineral industries is discussed
