European water frog hybrids Rana esculenta reproduce hemiclonally, by hybridogenesis: In the germ line they exclude the genome of the parental species Rana lessonae and produce haploid, unrecombined gametes with a genome of the parental species Rana ridibunda. These hybrids coexist with and depend as sexual parasites on the host parental species R. lessonae (the L-E population system); matings ...
In order to evaluate the suitability of maize hybrids in different planting dates, an experiment was conducted as split plot in JalilAbad, Varamin, Iran in 2015. Main and sub plots were planting date (D1: April 4, D2: April 19, D3: May 5, D4: May 20) and maize hybrids (H1: Gazda, H2: Maxima, H3: KSC 701, H4: AS160) respectively. Results indicated that there was variation between hybrids in term...
This experiment was conducted to determine the effect of selection index in four iranian commercial silkworm lines (107, 110, 153, 154) on resistance of their hybrids including 107×110, 110×107, 153×154, 154×153 under stress of nuclear polyhedrosis virus (N.P.V) Infection. Selection index program was performed on 3P commercial lines during 9 generations. Later generation parents of 3P lines wer...
Two types of natural hybrids were discovered in populations of three Hexagrammos species (Teleostei: Hexagrammidae) distributed off the southern coast of Hokkaido in the North Pacific Ocean. Both hybrids reproduce by hybridogenesis, in which the maternal haploid genome is transmitted to offspring without recombination and the paternal haploid genome is eliminated during gametogenesis. While nat...
چکیده «محکم و متشابه»، «نسخ» و «قرائات» از موضوعات مهم علوم قرآنی است. آیت الله معرفت در هر سه موضوع ضمن نقد دیدگاههای گذشته و رایج، به ارائه نظریاتی بدیع پرداخته اند. تعریف روشن از محکم و متشابه، تفاوت بین متشابه و مبهم، طبقه بندی تشابه به ذاتی و عرضی و ضابطه مند ساختن معانی تأویلی و باطنی، از جمله نوآوری های آیت الله معرفت در حوزه محکم و متشابه به شمار می رود. در موضوع نسخ، شاهد دو قرائت...
New bionanocomposite proton exchange membranes were prepared from sulfonated polybenzimidazole (s-PBI) and various amounts of sulfonated ZnO/cellulose nanohybrids (ZnO/cellulose-SO3H). The use of ZnO/cellulose-SO3H compensates for the decrease in ion exchange capacity of membranes observed when non-sulfonated nano-fillers are utilized. The strong –SO3H/–SO<su...
Developing bioactive implants with strong mechanical properties and biomineralization activity is critical in bone repair. In this work, modified cellulose nanofiber (mCNF)-reinforced glass (BG)-polycaprolactone (PCL) hybrids (mCNF–BP) biomechanics good apatite formation ability were reported. Incorporating mCNFs shortens the forming duration of hybrid films enhances biomechanical performance v...
Conducting polymer (CP) hybrids, which combine CPs with heterogeneous species, have shown strong potential as electrical transducers in chemosensors. The charge transport properties of CPs are based on chemical redox reactions and provide various chemo-electrical signal transduction mechanisms. Combining CPs with other functional materials has provided opportunities to tailor their major morpho...
Most of the known approved drugs comprise functionalized heterocyclic compounds as subunits. Among them, non-fluorescent quinazolines with four different substitution patterns are found in a variety of clinically used pharmaceuticals, while 4,5,7,8-substituted quinazolines and those displaying their own specific fluorescence, favourable for cellular uptake visualization, have not been described...
Vast amounts of cultivars of native plants are annually introduced into the semi-natural range of their wild relatives for re-vegetation and restoration. As cultivars are often selected towards enhanced biomass production and might transfer these traits into wild relatives by hybridization, it is suggested that cultivars and the wild × cultivar hybrids are competitively superior to their wild r...
