Childhood Obesity in the Region of Valencia, Spain: Evolution and Prevention Strategies
A. Morales,L. Jodar,G. Gonzalez,F.J. Santonja
Journal of Medical Sciences , 2008,
Abstract: In this study there are two main aims. The first one is to model and predict the incidence of obesity in the 3-5 years old population in the coming years in the region of Valencia, Spain. The second aim of this research is to use the constructed model to analyze the possible strategies in order to prevent the spread of obesity. At first a logistic regression statistical analysis of sociocultural variables of children with weight problems is performed. The result of this logistic regression statistical analysis suggests that sociocultural factors in the region of Valencia where the child grows up influence the development of overweight or obesity. Thus, this result permit to consider the hypothesis that the obesity is a health concern that depends on sociocultural factors and it is transmitted by the spread of unhealthy eating habits. In this way the hypothesis permits to construct a mathematical epidemiological type model in order to forecast obesity prevalence and to understand the mechanisms of the obesity spread. Using the constructed epidemiological mathematical model it is predicted that in the coming years, an increasing trend in the overweight and obese 3-5 years old children in the region of Valencia is predicted if the actual parameters of the mathematical model stay invariant. In addition, the different numerical simulations performed with the constructed epidemiological mathematical model indicate that the most likely successful strategy to tackle the obesity is through educational campaigns about the risk of unhealthy eating habits. This study shows how an epidemiological type mathematical model is an interesting tool to study the obesity transmissions dynamics in the population. It is useful to predict the prevalence of the obesity and study strategies to tackle it.
The use of ketamine in cancer palliation
F.J Smith
Southern African Journal of Anaesthesia and Analgesia , 2007,
Abstract: Cancer pain is caused by continuous tissue injury, which may be due to surgery, infiltration of the surrounding organs including nerves, as well as from mucositis after chemo- or radiotherapy. Nerve involvement, chronic opioid therapy and continuous nociceptive input cause hyperalgesia. Chronic stimulation of the dorsal root neurons leads to hyperalgesia and resistance (tolerance) to μ opioid analgesics (hyperalgesia-tolerance). The NMDA receptor antagonist ketamine reverses tolerance to morphine. Ketamine aggravates the sedative effect of opioids and other drugs used for neuropathic pain, such as sodium valproate and amitriptyline. The pain experienced by cancer patients needs a multimodal approach, including ketamine. Although ketamine appears to be a useful analgesic, the literature dealing with ketamine as an analgesic lacks randomised controlled trials.
Soil Patterns Associated with the Major Geological Units of the Kruger National Park
F.J. Venter
Koedoe : African Protected Area Conservation and Science , 1986, DOI: 10.4102/koedoe.v29i1.525
Abstract: The dominant soil types of the Kruger National Park and their interrelationships with parent material, topography and climate are discussed. The geogenetic and topogenetic nature of the soils are manifested in the strong correlations between recurrent soil patterns, major geological units and terrain morphology. The soils are categorised into seven major classes on the basis of the parent material from which they developed. General soil patterns within the major classes are discussed.
Soeklig op die Klerksdorp-kompleks
F.J. Potgieter
Koers : Bulletin for Christian Scholarship , 1969, DOI: 10.4102/koers.v37i2.1302
Abstract: Al vyf blanke universiteite van Transvaal is op die een of ander wyse gemoeid met die beplanningsnavorsingsprojek in die Klerksdorpse gebied wat op die oomblik aan die gang is. Vir dié navorsing het die Staat R18,000 bewillig, verskillende myngroepe altesaam R6,000, en plaaslike owerhede R1,500. En in die komitee wat beheer oor die navorsing uitoefen, is twee staatsdepartemente verteenwoordig, afgesien natuurlik van die verteenwoordiging van die betrokke universiteite.
Geografie en sy verhouding tot beplanning
F.J. Potgieter
Koers : Bulletin for Christian Scholarship , 1967, DOI: 10.4102/koers.v35i2.1374
Abstract: As die geografie hom besig hou met die studie van die aarde as woonplek van die mens, soos die meeste geograwe waarskynlik aanvaar, is dit logies dat die klem in die vak van tyd tot tyd sal verskuif namate die mens se tegnologiese vordering enersyds verandering aanbring in die onderlinge verhoudings van die samestellende dele van die menslike omgewing, en andersyds in die steeds veranderende wyse waarop die mens die aarde bewoon.
Constructing a spreadsheet simulation model of Chuck-a-luck: An application of logical functions
Rispoli, F.J.
Spreadsheets in Education , 2004,
Abstract: Chuck-a-luck is an inviting game played at carnivals in the Midwestern United States and England. A player picks a number from 1 to 6 and an operator rolls three dice. If the number chosen by the player comes up on all three dice, the player wins $3; if it comes up on two of the three dice, the player wins $2; if it comes up on one of the three dice, the player wins $1. Only if the chosen number does not appear at all does the player pay anything, which is just $1. We would like to know if Chuck-a-luck is a fair game, and what is its average payoff? In addition, we are interested in simulating this game using logical functions built into spreadsheet software as well as other computer programming languages.
i=0 (Information has no intrinsic meaning)
F.J. Miller
Information Research: an international electronic journal , 2002,
Abstract: This paper was written mainly to help identify some contradictions that can be found in the notion of knowledge management though its application is wider-ranging. The author suggests that knowledge - that is to say 'what we know' - can scarcely be understood and managed even by ourselves, much less by means of sophisticated information and communications (ie groupware and shareware) technologies. We have progressed from the industrial age through the information age into what is being promoted as the 'golden age' of knowledge and, in the process, we've been led to believe that information contains meaning - rather than just standing for, provoking or evoking meaning in others. The paper argues that unless we take the trouble to face and understand the significance and implications of i=0 (ie that information has no intrinsic meaning) and that knowledge is the uniquely human capability of making meaning from information - ideally in face-to-face relationships with other human beings - we may never emerge into any 'golden' age at all! The consequences of i=0 for communications, learning, safety, quality, management (itself), and winning work are also discussed.

Abstract: "Those were happy care-free, though at times, worrying, days, during which we were ill-equipped - the home front was ill organised - and fortunately had to fight only a half-hearted enemy." - Lt Col M. D. Mackenzie

Scientia Militaria : South African Journal of Military Studies , 2012, DOI: 10.5787/11-2-654
Abstract: It was only as a result of the enormous technological progress in the field of arms and the development of modern tendencies in the strategy and tactics of warfare, that the influence of an efficiently co-ordinated ground - and air force on the course of a conventional war was analysed. The purpose of this article is to analyse the influence of short-distance air transport support on unit tactical planning and operations and to make recommendations for the manner in which this support may be utilized to the full.

Scientia Militaria : South African Journal of Military Studies , 2012, DOI: 10.5787/4-1-927
Abstract: Die behoefte aan formele opleiding vir militêre aanvoering in Suid-Afrika bestaan sedert die eerste verdedigingskemas alhier ontwerp is. Hierdie tekort aan offisiere is aanvanklik uit die Garnisoen aan die Kaap bevredig. Toenemende militêre bedrywighede teen inboorlinge en die ontwikkeling van die kommandostelsel Nat sy eie militêre leiers voortgebring het, let al hoe duideliker die gebrek aan offisiere met 'n gespesialiseerde militêre kennis beklemtoon. Sulke offisiere kon egter nie anders as :leur formele opleiding beskikbaar gemaak Nord nie.
