Precision of Age Estimates Obtained from Five Calcified Structure for Wels Catfish, Silurus glanis
In this study, vertebrae, otoliths (asteriscus and lapillus), sectioned lapillus and pectoral fin rays were evaluated for age determination of Silurus glanis L., 1758 inhabiting Siddikli Dam Lake. All calcified structures showed the variable annual ring formation. Ages obtained from calcified structures were compared using the percentage of agreement (PA), average percentage of error (APE), and coefficient of variation (CV). Sectioned lapillus showed the clearest annulus formation and highest PA (76.4%) between readings, followed by asteriscus (43.9%), whole lapillus (40.5%), vertebrae (36.0%) and pectoral fin ray (33.3%). When sectioned lapillus compared to other structures, there were high ages obtained from this structure. Especially, the ages from the whole lapillus were lower than sectioned lapillus. Also, ages obtained from pectoral fin ray were the closer to sectioned lapillus ages than the other calcified structures. Owing to the highest PA, lowest APE and CV, sectioned lapillus was recommended as the most reliable calcified structure for age determination of S. glanis. Our findings can be used for effective fisheries management and determination of the biological characteristics of wels catfish
Türkiye'de pamuk yetiştiriciliğinin enerji bilançosu ve sera gazı emisyonlarının belirlenmesi: Diyarbakır İli Bismil İlçesi Örneği]
In this study, the energy balance and Greenhouse Gas Emissions (GHG) of cotton cultivation in Bismil district of Diyarbakır province in Turkey was defined. The energy balance and GHG of cotton cultivation was computed by conducting face to face surveys with 73 farms in the 2018-2019 cultivation season, which were selected by simple random sampling method. The energy input and output in cotton cultivation were computed as 54 617.62 MJ ha-1 and 65 984.42 MJ ha-1, respectively. Energy inputs occurs of electricity energy with 18 608.40 MJ ha-1 (34.06%), chemical fertilizers energy with 15 254.67 MJ ha-1 (27.93%), diesel fuel energy with 14 364.68 (26.30%), irrigation water energy with 3 559.50 MJ ha-1 (6.53%), machinery energy with 1 152.79 MJ ha-1 (2.11%), chemicals energy with 1 075.76 MJ ha-1 (1.96%), seed energy with 307.98 MJ ha-1 (0.57%), human labour energy with 293.84 MJ ha-1 (0.54%), respectively. Total energy inputs in cotton cultivation can be classified as 67.43% direct, 32.57% indirect, 7.62% renewable and 92.38% non-renewable. Energy use efficiency, specific energy, energy productivity and net energy in cotton cultivation were computed as 1.21, 9.77 MJ kg-1, 0.10 kg MJ-1 and 11 366.80 MJ ha-1, respectively. Total GHG emissions were computed as 6 482.36 kgCO2-eqha-1 for cotton cultivation with the greatest input part for electricity with 47.94% (3 107.60 kgCO2-eqha-1). The electricity followed up nitrogen with 16.29% (1 055.67 kgCO2-eqha-1), irrigation water with 14.82% (960.50 kgCO2-eqha-1), diesel fuel with 10.86% (704.08 kgCO2-eqha-1), seed with 3.07% (199.14 kgCO2-eqha-1 ), chemicals with 2.28% (147.76 kgCO2-eqha-1), phosphorous with 1.78% (115.64 kgCO2-eqha-1), human labour with 1.62% (104.94 kgCO2-eqha-1), machinery with 1.26% (81.85 kgCO2-eqha-1) and potassium with 0.08% (5.18 kgCO2-eqha-1), respectively. Additionally, GHG ratio value was computed as 1.16 kgCO2-eqkg-1 in cotton cultivation. © 2021 Namik Kemal University - Agricultural Faculty.

Multi-Scale Deformable Alignment and Content-Adaptive Inference for Flexible-Rate Bi-Directional Video Compression
The lack of ability to adapt the motion compensation model to video content
is an important limitation of current end-to-end learned video compression
models. This paper advances the state-of-the-art by proposing an adaptive
motion-compensation model for end-to-end rate-distortion optimized hierarchical
bi-directional video compression. In particular, we propose two novelties: i) a
multi-scale deformable alignment scheme at the feature level combined with
multi-scale conditional coding, ii) motion-content adaptive inference. In
addition, we employ a gain unit, which enables a single model to operate at
multiple rate-distortion operating points. We also exploit the gain unit to
control bit allocation among intra-coded vs. bi-directionally coded frames by
fine tuning corresponding models for truly flexible-rate learned video coding.
Experimental results demonstrate state-of-the-art rate-distortion performance
exceeding those of all prior art in learned video coding.Comment: Accepted for publication in IEEE International Conference on Image

Effect of micronized zeolite addition to lamb concentrate feeds on growth performance and some blood chemistry and metabolites
This study was conducted to determine the effects of the addition of micronized zeolite (MZ) on the fattening performance, blood parameters, faecal ash and nitrogen levels of lambs fed concentrate feeds intensively. For two months 25 four-month-old Merino x Ile de France crossbred male lambs (21.1 ± 1.32 kg live weight) were fed 100 g alfalfa hay and a mixed concentrate diet containing 0%, 1%, 2% or 3% additional MZ. At the end of the study, bodyweight gain and feed consumption were not affected by the treatments. Similarly, the addition of up to 2% MZ to the diet did not affect slaughter weight, hot carcass or cold carcass weights, but they decreased at 3% MZ inclusion. No differences were observed between the groups in terms of blood urea nitrogen, plasma glucose, serum creatinine, triglyceride, sodium, potassium and chlorine concentration. However, serum total protein, calcium and phosphorus concentrations were affected by MZ supplementation. The addition of MZ to the ration did not affect the faecal dry matter content and total nitrogen level, yet it increased the ash content of the faeces. Consequently, it was demonstrated that the addition of up to 2% MZ to lamb grower feed does not have a negative impact on performance and carcass yield of the animals, but affects serum total protein, calcium and phosphorus concentrations
Genetic diversity and population structure of Turkish native cattle breeds
Cattle are an important livestock species for human life, but certain breeds are at risk of extinction. Maintaining genetic diversity plays an important role in sustainable breeding and conservation programmes in farm animals. The aim of this study was to determine genetic diversity among five Turkish native cattle breeds. A total of 199 Turkish native cattle of the Native Southern Yellow (n = 40), South Anatolian Red (n = 40), Anatolian Grey Cattle (n = 40), Native Black Cattle (n = 39) and East Anatolian Red (n = 40) breeds were investigated using 22 autosomal microsatellite markers. The analysis revealed considerable genetic variation among these breeds. All loci were polymorphic, and a total of 545 alleles were found. Among these loci, only INRA032 was at Hardy-Weinberg equilibrium. Thirty-four private alleles with frequencies greater than 5% were found. Expected heterozygosity and polymorphic information content indexes were 0.87 and 0.88, respectively. Native Southern Yellow, South Anatolian Red and Native Black Cattle breeds were closely related.Keywords: animal genetic resources, microsatellite, genetic relationship, genetic conservatio
A Jupiter-mass planet around the K0 giant HD 208897
For over 10 years, we have carried out a precise radial velocity (RV) survey
to find substellar companions around evolved G,K-type stars to extend our
knowledge of planet formation and evolution. We performed high precision RV
measurements for the giant star HD 208897 using an iodine (I2) absorption cell.
The measurements were made at T\"UB\.ITAK National Observatory (TUG, RTT150)
and Okayama Astrophysical Observatory (OAO). For the origin of the periodic
variation seen in the RV data of the star, we adopted a Keplerian motion caused
by an unseen companion. We found that the star hosts a planet with a minimum
mass of m2sini=1.40MJ, which is relatively low compared to those of known
planets orbiting evolved intermediate-mass stars. The planet is in a nearly
circular orbit with a period of P=353 days at about 1 AU distance from the host
star. The star is metal rich and located at the early phase of ascent along the
red giant branch. The photometric observations of the star at Ankara University
Kreiken Observatory (AUKR) and the HIPPARCOS photometry show no sign of
variation with periods associated with the RV variation. Neither bisector
velocity analysis nor analysis of the Ca II and Halpha lines shows any
correlation with the RV measurements
