Evaluating the curriculum of the veterinary school of Firat University, Turkey, in terms of professional and technical skills

A significant portion of the problems faced by veterinarians is related to communication. These problems are intensely experienced between veterinary practitioners and animal owners; yet no lectures or courses aiming to improve professional skills are available in the curriculum of veterinary schools in Turkey. In this study, all students currently enrolled at, and 1992 and 1998 graduates of, the Veterinary School of Firat University (VSFU), Turkey, were surveyed to evaluate the attitudes of veterinary students and graduates toward technical and professional skills. Data were collected from 581 students and 61 recent graduates via personal interviews with students and questionnaires mailed to graduates; information was obtained about participants' technical and professional skills. The overall response rate was 85%. The results show that learning about technical and professional skills is highly valued; competence and comfort in skill sets are associated with comfort in establishing communication with instructors. Positive correlations were also noted between feeling comfortable with and feeling competent in both skill sets. In conclusion, it appears to be essential to introduce courses addressing improvement of professional skills to the curriculum of veterinary schools in Turkey, given that a successful veterinarian profile requires feeling competent in and comfortable with both technical and professional skills.     

Effect of fertilization of a biochar and compost amended technosol: Consequence on Ailanthus altissima growth and As- and Pb-specific root sorption

The remediation of metal(loid) polluted soil using plants (i.e. phytoremediation) often requires the application of amendments, as well as chemical fertilizer. However, such fertilizers can have negative effects when applied alone and can thus be applied together with other organic amendments to diminish this negative effect. Finally, plants to be used in phytoremediation should be selected based on their adaptive capacity and tolerance to poor and highly contaminated soils, characteristics that possesses Ailanthus altissima. The objective of this study was to evaluate the effects of osmocote fertilization on the amended mining technosol properties and plant growth parameters, as well as to study the accumulation pattern of As and Pb in plant roots. Results showed that osmocote ameliorated soil conditions, but increased Pb mobility. It also greatly improved plant growth. Finally, different behaviours of metal(loid) accumulation were observed in the roots: As was absorbed mainly in the roots because of its similarity with P, with very low amounts in the leaves, whereas Pb was adsorbed mainly on the root surface, with lesser proportion absorbed inside the root system.     

Drought Tolerance Aspects in Pearl Millet

Different indices for selection of lines grown under low and high water levels were examined from both theoretical and practical standpoints. Pearl millet ( Pennisetum americanum (L.) K. Schum) was planted under a sprinkler irrigation gradient in 1983 and 1984. Equations were developed for drought tolerance for both yield and forage production. Correlation coefficients were developed for yield and yield components.
The equations showed that drought will generally result in decreased productivity of both grain and forage. Grain yield was found to be positively correlated with seed weight and with the number of seeds in the main head, and negatively correlated with plant height under low water level. Dry matter was positively correlated with tiller number.     

Effect of Soil Applied Herbicids on Weed Flora, Yield Attributes, Oil Content and Constituents in Sunflower (Helianthus annuus L.)

Field experiments showed that superior control of the existing weed flora was obtained by applying: alachlor + linuron, alachlor + chloramben and cyanazine. Herbicidal treatments of alachlor, trifluralin, prometryn and oxadiazon were highly effective in controlling dominant weed species. Some herbicidal treatments produced sunflowers with larger head diameter as compared to unweeded check. As a result of suppressed weed interference, alachlor in combination with linuron or chloramben and cyanazine accounted for the highest seed yield values in 1985 and 1986.
Chemical analyses exhibited that sunflower oil content was not affected by weed control applications. Furthermore, oil constituents (oleic, linoleic, steric and palmitic fatty acids) expressed insignificant responses to applied treatments.     

Spinal fluid concentrations of mepivacaine in horses and procaine in cows after thoracolumbar subarachnoid analgesia

The CSF concentrations of mepivacaine in 10 Standardbred horses and of procaine in 10 Holstein cows given the drugs by thoracolumbar subarachnoid injection were determined. Mepivacaine hydrochloride was injected into the horses (502 +/- 60.5 kg) at an average dosage of 30 mg (1.5 ml of 20 mg/ml solution). Analgesia was produced 7.5 +/- 4.3 minutes after injection, extended between spinal cord segments T13 and L3 on both sides of the spinal column, and lasted 47 +/- 18.7 minutes at the T18 dermatome. Procaine hydrochloride was injected into cows (614 +/- 51.5 kg) at a dosage ranging between 75 mg and 100 mg (1.5 ml and 2 ml of 50 mg/ml solution). Analgesia was produced 8.2 +/- 2.0 minutes after injection, extended between spinal cord segments T11 and L4 on both sides of the spinal column, and lasted 47 +/- 17.5 minutes at the T13 dermatome. The critical CSF concentrations of local anesthetics required to eliminate response to pinprick stimulation were 204.4 +/- 90.3 micrograms of mepivacaine/ml in horses and 197.0 +/- 86.1 micrograms of procaine/ml in cows. Average CSF concentrations at 120 minutes after injections were made were 16.8 +/- 15.5 micrograms of mepivacaine/ml and 30.6 +/- 17.1 micrograms of procaine/ml. In in vitro experiments to determine the rates of hydrolysis of mepivacaine and procaine in CSF, significant changes (P greater than 0.05) were not seen in the CSF concentrations of mepivacaine in horses and procaine in cattle after a 120-minute incubation (37 C). The analgesic threshold concentrations of mepivacaine in CSF of horses and procaine in CSF of cows were similar.(ABSTRACT TRUNCATED AT 250 WORDS)     

Influence of dietary mineral imbalance on the incidence of urolithiasis in Egyptian calves

The influence of certain dietary elements on the urolithiasis syndrome in cattle calves was elucidated. Calcium, phosphorus, and magnesium measurements were conducted on feed rations as well as on serum and urine samples collected from affected and normal calves. Analysis of the rations given to the animals showed phosphorus at higher levels than calcium, indicating mineral imbalance. Serum and urine of urolithic calves were characterised by high phosphorus, calcium, magnesium, urea, and creatinine levels. Physical examination of urine of affected animals showed a high degree of turbidity, a large amount of calcium carbonate, and triple phosphate as well as abundant amount of pus cells and red blood cells. The characteristic clinical symptoms of urine retention were observed. Moreover, some animals were found to urinate through an opening in front of the scrotal region.     

Untersuchungen zum Einfluß von Konkurrenz auf die Bestandesentwicklung von Sommerraps bei unterschiedlicher Gunst der Umweltbedingungen

Investigations on the effect of competition with regard to the stand development of spring oilseed rape as dependent on environmental conditions
Field experiments were conducted to investigate the frequency distribution in spring oilseed rape as dependent on environmental growing conditions and plant density. As measures for frequency distribution skewness and kurtosis were estimated. The plant character determined was single plant dry matter. To understand the changes in the stand structure, samples were taken at the following developmental stages: rosette, begin of flowering, end of flowering and ripeness (harvest). Plant densities ranged from 60 plants/m², 90 plants/m² till 120 plants/m²
The results show that under unfavourable growing conditions, generally speaking, the values of (positive) skewness and kurtosis increase with the development of the plants; under favourable growing conditions, however, the values of skewness and kurtosis decrease from rosette till harvest.
Under unfavourable growing conditions as well as favourable ones, the values of skewness and kurtosis increase with strengthening of plant competition as consequence of increasing plant density. However, the trend during development and the height of the values as well as the quantitative relationships are strongly controlled by the general growing conditions. Frequency distribution, therefore, is not only a result of plant competition but also of differences in resources due to the general conditions of the location.
