The use of microtechnology’s in the construction of water aeration installations

Water aeration systems are highly efficient if the dispersion of air in the water is carried out in a controlled and uniform manner. The use of fine bubble generators ensures this and in addition, creates a small loss of pressure when air passes through them. The paper demonstrates that producing as few air bubbles as possible leads to a more efficient aeration process. Two water aeration installations are compared: - The first has a perforated plate with 152 orifices Ø 0.1 mm; - The second has four perforated plates, each with 113 orifices Ø 0.05 mm; Both installations are successively supplied with the same flow rate of compressed air, at the same temperature and at the same initial dissolved oxygen concentration in the water.

Coordinate Transformation Using the Author’s Software in GIS Class System – Case Study

In order to implement the provisions of the INSPIRE Directive, it is necessary for the Member States of the European Union to take appropriate measures to enable combining in a uniform manner spatial data deriving from different sources and sharing use of them by many users and many applications. Spatial data regarding underground hard coal mining in Poland should also be available in the national spatial reference system. Mining enterprises run a cartographic resource in the different rectangular flat coordinate systems. The standard transformation procedure does not provide the required accuracy because these are areas affected by mining activity, and the stability of points is limited, hence, studies were undertaken. The result is the development of software that can be used in Geographic Information Systems to transform spatial data from a system used in mine to the national system. The article described shortly a chosen coordinates systems used in Polish underground mines, elaborated procedure for selection of the degree and the type of a transformation polynomial in the transformation task. It presents its practical application of procedure for the area of one of hard coal mines using the author’s software elaborated in the results of above-mentioned research.

Romanian Slavonic in Unicode: problems and solutions

Editors of Slavonic and Slavonic–Romanian text can make use of a large variety of tools (fonts, physical and virtual keyboard layouts, word processors, operating systems) for transcribing and digitizing these texts in a uniform manner. The uniformity of the transcripts is based on Unicode standardization. Our study aims at explaining the place of Slavonic in Unicode and at briefly describing the most accessible tools. To this end, we shall describe the working tools from a historical and functional perspective and then provide examples in which those tools can be or have already been used to obtain a more accurate transcript. The user can choose from the existing methods and tools according to his/her purposes, needs and means. A better understanding of technical data can reduce the working time, improve transcription, accelerate learning times and generally make an editor’s work much easier.

VExD: A curated resource for human gene expression following viral infection

MotivationHuman viruses cause significant mortality, morbidity, and economic disruption worldwide. The human gene expression response to viral infection can yield important insights into the detrimental effects to the host. To date, hundreds of studies have performed genome-scale profiling of the effect of viral infection on human gene expression. However, no resource exists that aggregates human expression results across multiple studies, viruses, and tissue types.ResultsWe developed the Virus Expression Database (VExD), a comprehensive curated resource of transcriptomic studies of viral infection in human cells. We have processed all studies within VExD in a uniform manner, allowing users to easily compare human gene expression changes across conditions.Availability and ImplementationVExD is freely accessible at https://vexd.cchmc.org for all modern web browsers. An Application Programming Interface (API) for VExD is also available. The source code is available at https://github.com/pdexheimer/[email protected], [email protected]

Production of bacterial cellulose biopolymers in media containing rice and corn hydrolysate as carbon sources

Bacterial cellulose (BC) is a promising option for ecologically viable processes. In this work, BC was produced using starch hydrolysate (rice and corn flakes) as carbon sources. The starch was hydrolyzed by fungus for glucose production. A maximum yield of 2.80 ± 0.43 g/L of BC was obtained with the hydrolyzed rice medium. Moreover, BC produced in the rice and corn media had crystallinity of around 50%. Fourier-transform infrared spectrometry confirmed the functional groups in BC as well as the absence of contaminants from production process. The thermogravimetric analysis revealed that the polymers formed with alternative media had greater thermal stability. Scanning electron microscopy revealed a morphological structure with the random arrangement of nanofibrils in a non-uniform manner distributed in the weave of both polymeric films. The biofilms produced in different media had similar properties to those of films obtained with a conventional medium, revealing that the polymeric characteristics are not modified.

11. Conclusion

The Bible has been the source of great truth, goodness, and beauty at the same time as it has inspired lies, wickedness, and ugliness. What it has not produced is a uniform manner of its reading and interpretation. The very process of canonization is nevertheless part of an attempt to limit diversity and deviance of belief within religious communities. Ultimately, however, there is no controlling the way it is read. It is important therefore to be critically aware of the different kinds of uses to which the Bible may be put and to learn to discriminate among them. Readers need to exercise their own moral and aesthetic judgement over the different readings which have been offered of these texts, not least in their own traditions. At the same time, their own judgement will be influenced by the texts as they engage more closely with them and their reception.

Numerical Modeling and Sensitivity Analysis on Microwave Heating of Plastic on a Large Scale

To reduce the carbon emissions during heating in the manufacturing process, microwaves have attracted significant attention. Microwave has a lot of advantages rather than traditional heating method such as rapid heating, lower thermal damage and eco-friendly process. In order to apply microwaves to manufacturing process, uniform and efficient heating is required. We have analyzed the effect of various design parameters such as cavity heights, the application of the reflector, and the number and positions of waveguides for uniform and efficient heating by numerical simulation and verified that by experiment. The results showed that a slight change in the cavity height altered the electromagnetic field distribution and heating parameters, such as the coefficient of variance and power absorption efficiency. With reflectors installed, uniform heating was achieved and power absorption was improved, with the spherical reflector showing the maximum efficiency. The use of double waveguides heated the target material in a uniform manner. An increase in the power supply also led to uniform heating. This large-scale analysis will be helpful in applying microwaves to actual industrial sites.

GEODATA INTELLIGENCE FOR INTEROPERABLE DATA MANAGEMENT WITH THE ENVVISIO METHOD – ENVVISIO-GI

The objective of the envVisio method is to create generic tools and a flexible data backbone for the preparation, storage, linking and provision of complex and multi-thematic municipal geodata. Although geographic base data of the federal states in Germany are represented and processed in standardized and established data models and systems, there is also a large number of additional geodata such as environmental data and mobility data that are not managed in a uniform manner. Specifically, the envVisio method is about the further development of the model approaches for geospatial and environmental data provision. It is a new type of modeling method that has already been tested in individual state environmental authorities for interdisciplinary cooperation between the specialist departments. The development of technical solutions is intended to reduce the effort required to provide municipal geospatial data and to promote higher usability of public data. The aim of this article is to present the methods and the use cases to be implemented.

High-integrity human intervention in ecosystems: Tracking self-organization modes

Humans play major roles in shaping and transforming the ecology of Earth. Unlike natural drivers of ecosystem change, which are erratic and unpredictable, human intervention in ecosystems generally involves planning and management, but often results in detrimental outcomes. Using model studies and aerial-image analysis, we argue that the design of a successful human intervention form calls for the identification of the self-organization modes that drive ecosystem change, and for studying their dynamics. We demonstrate this approach with two examples: grazing management in drought-prone ecosystems, and rehabilitation of degraded vegetation by water harvesting. We show that grazing can increase the resilience to droughts, rather than imposing an additional stress, if managed in a spatially non-uniform manner, and that fragmental restoration along contour bunds is more resilient than the common practice of continuous restoration in vegetation stripes. We conclude by discussing the need for additional studies of self-organization modes and their dynamics.

On the scarcity of redshifted OH and millimetre-band molecular absorption

ABSTRACT Despite much searching, redshifted decimetre- and millimetre-band absorption by molecular gas remains very rare, limited to just six systems at zabs ≳ 0.05. Detection of these transitions can yield precise diagnostics of the conditions of the star-forming gas in the earlier Universe, the hydroxyl (OH) radical being of particular interest as in the λ = 18 cm ground state there are four different transitions located close to neutral hydrogen 21- cm and thus detectable with the Square Kilometre Array and its pathfinders. The four transitions of OH have very different dependences on the fundamental constants, thus having much potential in testing for any evolution in these over large look-back times. By collating the photometry in a uniform manner, we confirm our previous hypothesis that the normalized OH absorption strength is correlated with the optical–near-infrared red colour of the sightline. Applying this to the published searches, we find that all, but one (J0414+054), have simply not been searched sufficiently deeply. We suggest that this is due to the standard selection of sources with reliable optical redshifts introducing a bias against those with enough dust with which to shield the molecular gas. For the single source searched to sufficient depth, we have reason to suspect that the high degree of reddening arises from another system along the sightline, thus not being inconsistent with our hypothesis. We also show that the same optical redshift bias can account for the scarcity of millimetre-band absorption.
