Consider the following example (typical in college algebra): 1 x2 + 1 x2 + 1 + 1 x2 + x + 1 x2 + x+ 1 = 4x + 6x + 8x + 6x + 3x+ 1 x2(x+ 1) (x2 + 1) (x2 + x+ 1) . Now let’s assume that all the coefficients in the above are from the binary field F2 = Z2 = {0, 1}. The result becomes much cleaner: 1 x2 + 1 x2 + 1 + 1 x2 + x + 1 x2 + x+ 1 = 1 (x2 + x)(x4 + x) . After a brief introduction to finite f...

در هیبریدهای بین گونه‌ای بسته به ترکیب ژنتیکی والدین، گامت‌های کاهش نیافته به وفور تشکیل شده و فراوانی تشکیل آنها بیشتر از گونه‌های والدی است. تحقیق حاضر با هدف بررسی گامت‌های کاهش نیافته در هیبریدهای حاصل از تلاقی گندم نان (2n = 6x = 42, AABBDD) با دو گونه Aegilops cylindrica (2n = 4x = 28; CcCcDcDc) و Ae. triuncialis (2n = 4x = 28; UtUtCtCt) انجام شد. فرض این بود که دانه‌های گرده کاهش نیافته ...

The present paper deals with meiotic studies in 15 species belonging to 6 genera of the tribe Cichorieae from various localities of Western Himalayas. The chromosome number has been reported for the first time in Hieracium crocatum (2n = 10) and Lactuca lessertiana (2n = 2x = 16). Further, intraspecific variability has been reported for the first time in H. umbellatum (2n = 2x = 10 and 2n = 6x ...

We prepared rod-shaped gold nanorattles solid gold nanorods surrounded by a thin gold shell using a galvanic replacement process starting with silver-coated gold nanorods. These structures are very promising candidates for catalytic applications and optimized plasmon sensors. They combine the advantages of rods (low plasmon resonance frequency, large polarizability, small damping) with the high...

Most members of the subfamily Mimosoideae have pantropical distributions, variable habits, and a basic chromosome number x = 13. We examined karyotypic evolution of 27 species of this subfamily occurring principally in northeastern Brazil by examining chromosomes stained with Giemsa. All of the species had semi-reticulated interphase nuclei and early condensing segments in the proximal region o...

We present Mlcached, multi-level DRAM-NAND keyvalue cache, that is designed to enable independent resource provisioning of DRAM and NAND flash memory by completely decoupling each caching layers. Mlcached utilizes DRAM for L1 cache and our new KVcache device for L2 cache. The index-integrated FTL is implemented in the KV-cache device to eliminate any inmemory indexes that prohibit the independe...

Chromosome number and meiotic behavior were evaluated in 36 Brazilian accessions of the grass Paspalum (which had never previously been analyzed) to determinate which accessions might be useful in interspecific hybridizations. The analysis showed that one accession of Paspalum coryphaeum was diploid (2n = 2x = 20) and one accession of Paspalum conspersum hexaploid (2n = 6x = 60), the remaining ...

Karyological investigations were carried out on four species of Bellevalia Lapeyrouse, 1808 and Muscari Miller, 1758 (Asparagaceae) sampled in contrasting bioclimatic conditions of Algeria. The endemic Bellevalia mauritanica Pomel, 1874 was found to have a tetraploid cytotype 2n = 4x = 16 and an octoploid 2n = 8x = 32 which is a new report. The chromosome number 2n = 2x = 18 in Muscari comosum ...

Triticum genus encloses several tetraploid species that are used as genetic stocks for expanding the genetic variability of wheat (Triticum aestivum L.). Although the T. aestivum (2n = 6x = 42, AABBDD) and T. durum (2n = 4x = 28, AABB) karyotypes were well examined by chromosome staining, Giemsa C-banding and FISH markers, other tetraploids are still poorly characterized. Here, we established a...

BACKGROUND Drugs of plant origin such as Arnica montana, Calendula officinalis or Hypericum perforatum have been frequently used to promote wound healing. While their effect on wound healing using preparations at pharmacological concentrations was supported by several in vitro and clinical studies, investigations of herbal homeopathic remedies on wound healing process are rare. The objective of...
