With the development of motorized spindle, cooling effect and distribution capacity become crucial problem system. An optimization method for thermoelectric-based system (TECS) is proposed based on conservation energy to distribute capacity. The main strategy make cold heat input at different regions spindle sleeve equal in real-time through optimizing contact area between conduction (HCS) slee...

The meiosis II spindle of Drosophila oocytes is distinctive in structure, consisting of two tandem spindles with anastral distal poles and an aster-associated spindle pole body between the central poles. Assembly of the anastral:astral meiosis II spindle occurs by reorganization of the meiosis I spindle, without breakdown of the meiosis I spindle. The unusual disk- or ring-shaped central spindl...

Background: Mammalian oocyte undergoes a series of structural nuclear modulations during maturation in order to obtain full competence to support fertilization and early embryonic development. Microtubules are major cytoskeleton components and have pivotal modulators for chromosomal movement, and it has been shown that partial or immature spindle organization may compromise correct ploidy of th...

Spindle length varies dramatically across species and during early development to segregate chromosomes optimally. Both intrinsic factors, such as regulatory molecules, and extrinsic factors, such as cytoplasmic volume, determine spindle length scaling. However, the properties that govern spindle shape and whether these features can be modulated remain unknown. Here, we analyzed quantitatively ...

Molecular motors are required for spindle assembly and maintenance during cell division. How motors move and interact inside spindles is unknown. Using photoactivation and photobleaching, we measure mitotic motor movement inside a dynamic spindle. We find that dynein-dynactin transports the essential motor Eg5 toward the spindle poles in Xenopus laevis egg extract spindles, revealing a direct i...

Dynein mediates spindle positioning in budding yeast by pulling on astral microtubules (MTs) from the cell cortex. The MT-associated protein She1 regulates dynein activity along astral MTs and directs spindle movements toward the bud cell. In addition to localizing to astral MTs, She1 also targets to the spindle, but its role on the spindle remains unknown. Using function-separating alleles, li...

Maintenance of production machines is a control to maintain the productivity process. PT. Symgreen company that produces ice cream sticks. To achieve optimal results, regular machine maintenance required. The occurrence damage experienced during process, in some components, so results were reduced. Failure Mode and Effect Analysis method used identify failure mode overcome every breakdown. dete...

Due to climate changes, drought- and lime-tolerant Prunus mahaleb rootstock may gain importance. Among the Mahaleb rootstocks hybrids, there are standard moderate-vigorous types, but their intensive testing in orchards is still needed. Our paper reports on SL 64, Bogdány, Magyar, SM 11/4 clonal Mahalebs, hybrid MaxMa 14. ‘Carmen’, ‘Vera’, ‘Paulus’, ‘Rita’ sweet cherry trees were trained above p...
