Factors influencing the drain and rinse operation of Banana screens. The impacts of the following system variables were investigated: panel angle, volumetric feed flow rate, solids content of feed screen motion, vibration frequency, magnetite content and impact of screen aperture.
Vibration characteristics of an inclined flip-flow screen panel in banana flip-flow screens. A banana flip-flow screen is an effective solution for the screening of high-viscosity, high-water and fine materials. As one of the key components, the vibration characteristics of the inclined flip-flow screen panel largely affects the screen performance and the processing capacity. In this paper, a mathematical model for the vibration characteristic of the inclined flip-flow screen panel is proposed based on Catenary theory.
The reasonability of Catenary theory in analyzing the vibration characteristic of flip-flow screen panels is verified by a published experiment. Moreover, the effects of the rotation speed of exciters, the incline angle, the slack length and the characteristics of the screen on the vertical deflection, the vertical velocity and the vertical acceleration of the screen panel are investigated parametrically.
The results show that the rotation speed of exciters, the incline angle, the slack length and the characteristics of the screen have significant effects on the vibrations of an inclined flip-flow screen panel, and these parameters should be optimized. Fruit Peel. Pectinase is the one of most important enzyme which is used in food industry such as fruit and vegetable juice extraction, oil extraction and fermentation of coffee, cocoa and tea.
Pectinase can be produced by microorganism such as bacteria and fungi. Fungi are known as potent producer of pectinase. This research was conducted to isolate and screen of the pectinolytic fungi from rotten orange and banana fruit peels.
This research succeeded to isolate 10 fungal isolates from rotten orange peels and 5 fungal isolates from rotten banana peels. These isolates were screened in pectinolytic activities based on clear zone formation on pectic medium which is stained by cetyl trimethyl ammonium bromide.
The highest pectinolytic activity was showed by Penicillium O2 which was isolated from orange peel. Identification of genes differentially expressed during ripening of banana. The banana Musa acuminata, subgroup Cavendish 'Grand Nain' is a climacteric fruit of economic importance. A better understanding of the banana ripening process is needed to improve fruit quality and to extend shelf life. Eighty-four up-regulated unigenes were identified by differential screening of a banana fruit cDNA subtraction library at a late ripening stage.
The ripening stages in this study were defined according to the peel color index PCI. Unigene sequences were analyzed with different databases to assign a putative identification. Expression profiles were obtained for unigenes annotated as orcinol O-methyltransferase, putative alcohol dehydrogenase, ubiquitin-protein ligase, chorismate mutase and two unigenes with non-significant matches with any reported sequence.
Similar expression profiles were observed in banana pulp and peel. Our results show differential expression of a group of genes involved in processes associated with fruit ripening, such as stress, detoxification, cytoskeleton and biosynthesis of volatile compounds.
Some of the identified genes had not been characterized in banana fruit. Besides providing an overview of gene expression programs and metabolic pathways at late stages of banana fruit ripening, this study contributes to increasing the information available on banana fruit ESTs.
In most cases, parents don't hear Chemical compatibility screening test results. A program for evaluating packaging components that may be used in transporting mixed-waste forms has been developed and the first phase has been completed. This effort involved the screening of ten plastic materials in four simulant mixed-waste types.
These plastics were butadiene-acrylonitrile copolymer rubber, cross-linked polyethylene XLPE , epichlorohydrin rubber, ethylene-propylene rubber EPDM , fluorocarbon Viton or Kel-F , polytetrafluoroethylene, high-density polyethylene HDPE , isobutylene-isoprene copolymer rubber butyl , polypropylene, and styrene-butadiene rubber SBR. The seal materials were tested using vapor transport rate VTR measurements while the liner materials were tested using specific gravity as a metric.
For these tests, a screening criterion of 0. In the chlorinated hydrocarbon simulant mixed waste, only Viton passed the screening tests. In both the simulant scintillation fluid mixed waste and the ketone mixture simulant mixed waste, none of the seal materials met the screening criteria. For specific gravity testing of liner materials, the data showed that while all materials with the exception of polypropylene passed the screening criteria, Kel-F, HDPE, and XLPE offered the greatest resistance to the combination of radiation and chemicals.

The Banana Genome Hub. PubMed Central. The banana reference genome sequence Musa acuminata was recently released.
Given the taxonomic position of Musa, the completed genomic sequence has particular comparative value to provide fresh insights about the evolution of the monocotyledons. The study of the banana genome has been enhanced by a number of tools and resources that allows harnessing its sequence. First, we set up essential tools such as a Community Annotation System, phylogenomics resources and metabolic pathways. Then, to support post-genomic efforts, we improved banana existing systems e.
SNP and polymorphism analysis. Several uses cases illustrate how the Banana Genome Hub can be used to study gene families. Overall, with this collaborative effort, we discuss the importance of the interoperability toward data integration between existing information systems.
Screening the banana biodiversity for drought tolerance: can an in vitro growth model and proteomics be used as a tool to discover tolerant varieties and understand homeostasis. There is a great need for research aimed at understanding drought tolerance, screening for drought tolerant varieties and breeding crops with an improved water use efficiency.
Bananas and plantains are a major staple food and export product with a worldwide production of over million tonnes per year.
Water however is the most limiting abiotic factor in banana production. A screening of the Musa biodiversity has not yet been performed. To screen the Musa biodiversity for drought tolerant varieties, we developed a screening test for in vitro plants. The ABB variety showed the smallest stress induced growth reduction.
To get an insight into the acclimation and the accomplishment of homeostasis, the leaf proteome of this variety was characterized via 2D DIGE. After extraction of the leaf proteome of six control and six stressed plants, spots could be distinguished. A PCA analysis indicates that control and stressed plants can blindly be classified based on their proteome.
Twenty four differential proteins could be identified. Natural Radioactivity in Bananas. We have collected several samples of bananas prata and nanica, its peels, leaves, and also different soils where the banana tree was planted, such as soil with a standard amount of fertilizer, the fertilizer itself and also soil without fertilizer for comparison. We have used the gamma-ray spectroscopy technique with a NaI T1 crystal inside a 12 cm thick lead shield to detect the gamma-radiation.
The results indicate that only part of the available potassium is absorbed by the plant, which is mainly concentrated in the banana peel. In vitro digestibility of banana starch cookies. Banana starch was isolated and used for preparation of two types of cookies. Chemical composition and digestibility tests were carried out on banana starch and the food products, and these results were compared with corn starch.
Ash, protein, and fat levels in banana starch were higher than in corn starch. The high ash amount in banana starch could be due to the potassium content present in this fruit. Proximal analysis was similar between products prepared with banana starch and those based on corn starch.
The cookies had lower available starch than the starches while banana starch had lower susceptibility to the in vitro alpha-amylolysis reaction. Banana starch and its products had higher resistant starch levels than those made with corn starch. For some of the spectral bands this proves to be much too bright a signal that results in the saturation of detectors designed for measuring low reflectance ocean surfaces signals.
A mechanical attenuation device in the form of a pin hole screen is used to reduce the signals to calibrate these bands. The sensor response to solar illumination of the SD with and without the attenuation screen in place will be presented. The MODIS detector response to the solar diffuser is smooth when the attenuation screen is absent, but has structures up to a few percent when the attenuation screen is present. This structure corresponds to non-uniform illumination from the solar diffuser.
Each pin hole produces a pin-hole image of the sun on the solar diffuser, and there are very many pin hole images of the sun on the solar diffuser for each MODIS detector. Even though there are very many pin-hole images of the sun on the solar diffuser, it is no longer perfectly uniformly illuminated.
This non-uniformly illuminated solar diffuser produces intensity variation on the focal planes. The results of a very detailed simulation will be discussed which show how the illumination of the focal plane changes as a result of the attenuation, and the impacts on the calibration will be discussed. Part of persons they have hearing loss between 5 to 10 percent increases from 2. The incidence of persons with respective without middle ear inflammation in anamnesis only differ in stages about 20 percent hearing loss.
It shows sensitivity of screening audiometry nevertheless there are possibilities of mistakes. Adolescents already may show measurable hearing loss in connection with professional and nonprofessional expositions as well as individual dispositions. Let's Go Bananas.

Using bananas as a theme, science, mathematics, social studies, music, and writing are integrated into the curriculum of…. A simple diffraction experiment was designed using banana stem as natural grating.
Coherent beams of lasers with wavelengths of The diffraction experiments were able to measure the distances between the slit of the banana stem, i. Banana is one of the major crops of India with increasing export potential.
It is important to estimate the production and acreage of the crop. Thus, the present study was carried out to evolve a suitable methodology for estimating banana acreage.
Area estimation methodology was devised around the fact that unlike other crops, the time of plantation of banana is different for different farmers as per their local practices or conditions. Thus in order to capture the peak signatures, biowindow of 6 months was considered, its NDVI pattern studied and the optimum two months were considered when banana could be distinguished from other competing crops.
The final area of banana for the particular growing cycle was computed by integrating the areas of these two months using LISS III data with spatial resolution of 23m. Estimated banana acreage in the three districts were Ha, ha and Ha for Bharuch, Anand and Vadodara respectively with corresponding accuracy of

Sterile inflammation and pregnancy complications: a review
Inflammation is essential for successful female reproduction. Inflammatory processes are implicated in every step of fertility from menstrual cycle ovulation and menses to early pregnancy implantation and decidualization and later during labor myometrial activation, cervical ripening and weakening of fetal membrane , whereas quiescence of these mechanisms is maintained by local immune cells during gestation to allow maternal tolerance of fetal antigen allograph. However, untimely inflammatory triggers shifting the immunological balance toward activation can lead to adverse pregnancy outcomes including preterm birth. Inversely, failure to mount a local inflammatory response in early or late gestation can also lead to adverse conditions, including miscarriages. Therefore, understanding the mechanisms by which inflammation is untimely triggered in the uterus is fundamental to developing effective therapeutics to improve fertility and decrease poor obstetrical outcomes.
