Buying veterinary products : read the label first
Chenicals for animal health, and processed feeds must be registered and labelled.
Registration is intended to insure that products are effective for the purpose they are sold, and safe when used according to instructions.
It is important to read the lable to understand the correct use of the product
Two causes of reduced profit from pigs
LOSS of condition in a pig affects profits more severely than slow rate of growth.
Two common symptoms, scouring and itching, cause weight loss and are followed by a period of reduced weight gain
First year student expectations: Results from a university-wide student survey
Although much has been written on the first-year experience of students at higher education institutions, less attention has been directed to the expectations of students when they enter an institution for the first time. This paper provides additional insights into the expectations of students at an Australian university and highlights areas in which students’ expectations may not necessarily align with the realities of common university practices. By providing opportunities for students to articulate their expectations, staff are able to use the responses for a constructive dialogue and work towards a more positive alignment between perceived expectations and levels of student satisfaction with their experience.Geoffrey Crisp, Edward Palmer, Deborah Turnbull, Ted Nettelbeck, Lynn Ward, Amanda LeCouteur, Aspa Sarris, Peter Strelan, and Luke Schneide
Serum Cytokine Levels In Autoimmune And Non-autoimmune Hyperthyroid States.
Although the role of interleukin-2 (IL-2) and interferon gamma (gammaIFN) is still poorly understood in hyperthyroid diseases, it is reasonable to assume that these cytokines may be present at higher levels in Graves' disease (GD) than in other primarily non-autoimmune thyroid diseases. In order to look for an easy method to distinguish GD from primarily non-autoimmune causes of hyperthyroidism, we compared 13 healthy individuals with 21 treated and untreated hyperthyroid GD patients and with 19 patients with hyperthyroidism due to other etiologies: 7 cases of multinodular goiter, 5 cases of excessive hormone replacement and 7 cases of amiodarone-associated hyperthyroidism. All patients presented low TSH levels and a dubious clinical thyroid state. We found a good correlation between TSH and serum IL-2 levels (r = 0.56; P<0.01). Serum IL-2 (P<0.01) and gammaIFN (P<0.01) levels were lower in the hyperthyroid group of patients than in control subjects, suggesting a depressed TH1 pattern in the T-cell subset of hyperthyroid patients. GD had normal IL-2 levels, while patients with other forms of thyrotoxicosis presented decreased IL-2 levels (P<0.05). There was no difference between treated and untreated GD patients. We suggest that the direct measurement of serum IL-2 level may help to confirm hyperthyroidism caused by GD.3365-
Chinese Magic in Loop Integrals
We present an approach to higher point loop integrals using Chinese magic in
the virtual loop integration variable. We show, using the five point function
in the important e^+e^-\to f\bar{f}+\gamma process for ISR as a pedagogical
vehicle, that we get an expression for it directly reduced to one scalar
5-point function and 4-, 3-, and 2- point integrals, thereby avoiding the
computation of the usual three tensor 5-pt Passarino-Veltman reduction. We
argue that this offers potential for greater numerical stability.Comment: 11 pages, 1 figure; improved figure, improved text and

Quality of Neonatal Health Care: Learning From Health Workers’ Experiences in Critical Care in Kilimanjaro Region, Northeast Tanzania
Neonatal deaths are generally attributed to suboptimal standards of health care. Health care worker motivation and adherence to existing guidelines are rarely studied. To assess the performance of health workers for neonatal health care in the hospitals of Kilimanjaro region. A descriptive study using a semi-structured interview for health care workers at a tertiary referral hospital and peripheral health facilities (regional referral, district hospitals and health centres).was used. Health Care Workers (HCW) were asked to recall a scenario of a critically ill neonate admitted in the wards and the treatment that was provided. The WHO Emergency Triage Assessment and Treatment (ETAT) guidelines were used as a standard reference for knowledge of critical care. Birth asphyxia was the most recalled health problem requiring critical care, reported by 27.5% of 120 HCW at both peripheral hospitals and by 46.4% of 28 health workers in tertiary referral centres. Half of the HCW commented on their own performance (47.5%, n=140). HCW presented with low to moderate levels of knowledge for critical care were at 92%. Supplementary training was associated with a higher levels of knowledge of neonatal critical care (p value = 0.05). HCW in peripheral hospital had lower levels of knowledge (only 44.7% at peripheral hospitals had sufficient ratings compared to 82.1% at the referral centre). [Pearson χ2 (2) = 12.10, p value = 0.002]. Guided Practical-Competence Diagnostic Specific neonatal health care training is highly needed in the peripheral facilities of rural Kilimanjaro region
Massive Elementary Particles and Black Holes
An outstanding problem posed by Einstein's general theory of relativity to
the quantum theory of point particle fields is the fate of a massive point
particle; for, in the classical solutions of Einstein's theory, such a system
should be a black hole. We use exact results in a new approach to quantum
gravity to show that this conclusion is obviated by quantum loop effects.
Phenomenological implications are discussedComment: 11 pages; 1 figure; improved text relating to asymptotic safet

Scattering loss in electro-optic particulate composite materials
The effective permittivity dyadic of a composite material containing
particulate constituent materials with one constituent having the ability to
display the Pockels effect is computed, using an extended version of the
strong-permittivity-fluctuation theory which takes account of both the
distributional statistics of the constituent particles and their sizes.
Scattering loss, thereby incorporated in the effective electromagnetic response
of the homogenized composite material, is significantly affected by the
application of a low-frequency (dc) electric field
