Biosecurity levels of livestock enterprises in Turkey and factors affecting these levels
Biosecurity (BS) is a multidimensional preventive medicine approach that has health, technical, and financial aspects. The purpose of this study was to determine the differences of the BS scores belonging to the livestock enterprises depending on the geographical region and breeding types and to predict the socioeconomic factors having an impact over the BS level. The study was conducted with 517 breeders who live in 7 different regions of Turkey. The results have revealed that the enterprises performing “beef cattle fattening and dairy cattle breeding together” have higher BS scores than the enterprises in the other breeding category (P < 0.01). The differences between the technical and financial scores according to geographical regions were statistically significant (P < 0.01). The regions categorized as “west” have the highest score and “south” have the lowest score. It was determined that as the “educational level of the breeder” and “enterprise scale” increased, the BS score significantly went up. The regression model was found significant as a whole (P < 0.01) and the independent variables explained the variation in the technical and financial BS scores to be 14.6% and 12.7%, respectively. Dissemination of education/training practices and increasing enterprise scales will positively affect the level of BS in the sector. © TÜBITA
Spinal cord stimulation in failed back surgery
Objective: Spinal cord stimulation is used for
treating failed back surgery syndrome, chronic
arachnoiditis, peripheral neuropathies, postamputation
phantom pain, complex regional pain syndrome and
pain secondary to spinal cord injury. In this study we
present 7 cases with intractable neuropathic radicular
pain which developed following spine surgery.
Material and Methods: Spinal cord stimulation
was applied to 7 (3male/4 female) patients who had
failed back surgery syndrome and pain resistant to
medical and invasive methods, with the council
decision, which included neurosurgery, neurology,
and psychiatry. One week stimulation trial was
applied to all cases.
Results:The mean age of the patients was
54.85±7.64 years. The mean of pain intensity in
Visual Analog Scale was 8.71±0.74 at preoperative
status and post operative pain intensity was 2.27±0.67
at 6 months. Pain intensity significantly decreases
after spinal cord stimulation (p=0.000). One of the
three cases who had unsuccessful trial period received
morphine pump implantation, and percutaneous
lumbar sympathectomy was applied to another one.
One case who received permanent implantation was
replaced to another location due to skin erosion. There
was no morbidity.
Conclusion: Spinal cord stimulation is an effective
tool in reducing pain, in patients who have
unsuccessful lower back surgery with the correct
indications
A new species of pseudophoxinus (Teleostei: Cyprinidae) from Southwestern Anatolia, Turkey
YOGURTCUOGLU, Baran/0000-0001-8144-6191;WOS: 000363695700006PubMed: 26624395Pseudophoxinus mehmeti, new cyprinid species from the Alankoy basin in south-western Turkey, is distinguished from all species of Pseudophoxinus in adjacent regions by the combination of the following characters: body slender, its length 1.3-1.5 times its depth; caudal peduncle length 1.6-2.0 times its depth; mouth almost superior, with the tip of the mouthcleft approximately level with the middle of the pupil; snout with a pointed tip, its length markedly greater than eye diameter; lateral line not complete, with 30-50 perforated scales and 48-60+2 scale rows in lateral series; 111/2-131/2 scale rows between lateral line and dorsal-fin origin, 31/2-51/2 scale rows between lateral line and anal-fin origin; dorsal-fin with 61/2-71/2 branched rays; anal-fin with 61/2-71/2 branched rays; a distinct black epidermal stripe from eye to caudal-fin base in preserved individuals
Scattering of Woods-Saxon Potential in Schrodinger Equation
The scattering solutions of the one-dimensional Schrodinger equation for the
Woods-Saxon potential are obtained within the position-dependent mass
formalism. The wave functions, transmission and reflection coefficients are
calculated in terms of Heun's function. These results are also studied for the
constant mass case in detail.Comment: 14 page
Analytical Solutions of Klein-Gordon Equation with Position-Dependent Mass for q-Parameter Poschl-Teller potential
The energy eigenvalues and the corresponding eigenfunctions of the
one-dimensional Klein-Gordon equation with q-parameter Poschl-Teller potential
are analytically obtained within the position-dependent mass formalism. The
parametric generalization of the Nikiforov-Uvarov method is used in the
calculations by choosing a mass distribution.Comment: 10 page
Approximate Solution of the effective mass Klein-Gordon Equation for the Hulthen Potential with any Angular Momentum
The radial part of the effective mass Klein-Gordon equation for the Hulthen
potential is solved by making an approximation to the centrifugal potential.
The Nikiforov-Uvarov method is used in the calculations. Energy spectra and the
corresponding eigenfunctions are computed. Results are also given for the case
of constant mass.Comment: 12 page
The Changing Waves of Migration from the Balkans to Turkey: A Historical Account
Ahmet İçduygu and Deniz Sert tell the history of migration from the Balkans to Turkey from the end of the nineteenth century to the present. They relate this history to nation-building, but also to economic conditions and specific Turkish concerns, such as the perceived need for immigration to compensate for a declining population at that time. They also demonstrate that after 1990, ethnic migration decreased and irregular labour migration became more important
