In this research the metaphase chromosome number and karyotype of Astragalus stenosemioides species growing naturally in Turkey are studied. The study revealed that A. is 2n = 16. basic determined as x 8. formula 8m. total length somatic chromosomes ranges between 1.96 - 3.38 μm. haploid 21.36 addition, asymmetry was evaluated by different methods; Stebbins classification, TF%, AsK%, Syi Rec, A...

Agricultural sustainability has become a major concern in arid regions of China. In order to better understand the influence of continuous cropping on soil quality, six experimental fields were established in the Alar Oasis of Xinjiang, including uncultivated land (as a zero year treatment duration) and five different continuous cropping years on cotton fields, with different cropping durations...

In this study three polyploid Arum Linnaeus, 1753 species from Southern Italy were chromosomally investigated. Arum italicum Miller, 1768 was found to have 2n = 84 chromosomes and a karyotype composed of numerous asymmetric chromosomes. Arum maculatum Linnaeus, 1753 and Arum apulum (Carano) P. C. Boyce, 1993 were found to have 2n = 56 chromosomes. In the examined taxa some chromosome pairs were...

Unlike existing methods for communication delays, the design presented here identifies and continuously moves the rightmost eigenvalues to desired positions. Signal tran...

Fractures of the adult anlde with disruption of the tibiofibular syndesmosis call for sufficient stabilization of the ankle mortise to ensure proper healing of the syndesmotic ligaments. Several internal fixation techniques for stabilization of the syndesmosis have been employed in the past, including 3.5 mm, 4.5 mm, and 5.0 mm metallic and bioabsorbable screws, 1.5 mm and 1.5 mm Kirschner wire...

Günümüzde yağışların azalmasına bağlı olarak su kaynaklarımızı tehdit eden en önemli etkenlerin başında kuraklık gelmektedir. Kuraklık etkilerinin aza indirebilmesi amacıyla yapılacak çalışmaların başında, kuraklığın süre, şiddet ve tekrarlanma periyodunun hassas bir şekilde belirlenmesi Bu çalışmada elde edilen sonuçlara göre, 1959-2019 yılları arasında Akşehir Devlet Meteoroloji İstasyonunda ...

The asymmetry indexes have helped cytotaxonomists to interpret and classify plant karyotypes for species delimitation efforts. However, there is no consensus about the best method to calculate the intrachromosomal asymmetry. The present study aimed to compare different intrachromosomal asymmetry indexes in order to indicate which are more efficient for the estimation of asymmetry in different g...
