Streszczenie:

The saw gin stand is the heart of the saw ginning system. From the initial filing of patents for the spiked-tooth gin and the saw gin in 1794 and 1796 by Whitney and then Holmes, respectively, the saw gin stand has predominated over early roller-type gins in the U.S. cotton ginning industry. These early saw gin stands were small, simple, and were manually fed hand-picked seed cotton and processed only a few hundred pounds of fiber per day. However, at this early stage, it was recognized that the gin stand had a huge impact on fiber quality and textile utility. These early saw gins tended to be single-stand installations that consisted of a gin stand and a bale press. The basic operating principle of separating fiber and seed by pulling the cotton fiber through narrow slots that blocked the passage of the cottonseed in these early saw gins has not changed. However, the size and complexity of the saw gin stand and the ginning system, of which the saw gin is the heart, has changed by orders of magnitude. The most recent Cotton Ginners Handbook documented all of the manufacturers and specifications of U.S. saw gins that were being used in the cotton industry at that time. Subsequently the saw gin has continued to evolve and some gin manufacturers are no longer in business whereas others have entered the field. This document provides the U.S. ginning industry the most recent information available on saw gin stands currently operating in the U.S.

Abstract. The trend in modern gin stand designs to increase gin stand production rate in terms of bales/h was generally achieved by increased width, narrower saw spacing, and higher saw loading. This study examined fiber length reductions, short fiber content, fiber neps, and cottonseed damage associated with five saw gin stands of differing production rates, design, and manufacture that represent a range of gin technologies developed since the 1960s to identify technologies from those earlier designs that may guide future gin stand research. Based on rated ginning rate, the gin stands were classified in two general categories, lower capacity (LC, 5 bales/h and less) and higher capacity (HC, 7.5 bales/h and higher). Fiber from the LC gin stands contained fewer fiber neps, longer fibers, less short fiber, and less foreign matter than fiber from the HC gin stands. In addition, cottonseed from the gin stand with lowest capacity had the highest residual linters content and the lowest overall seed damage which aligned with the short fiber content data. Both the LC gin stands were older models and had wider saw spacing; the oldest of them was substantially different from the other designs with two saw mandrels pulling fiber from the same seed roll position. Study results indicate that there may be historical gin stand technologies and relationships between gin parameters such as ginning rate per saw, saw spacing, and seed roll density, and fiber and seed quality that need to be further investigated. Keywords: Cottonseed quality, Cotton ginning, Fiber quality, Gin stand, Length, Neps, Short fiber content, Upland cotton.

Processing capacities of new high-speed roller ginning technology approaches that of saw ginning. Spinning mills are interested in mill performance data comparing new upland cultivars processed by both saw and roller ginning. Four diverse upland cultivars were processed by saw ginning and high-speed roller ginning and analyzed by ginning method. Ring-spun carded and combed yarns were produced, and their properties determined. Results overall (combining cultivars) showed that the roller gin, when compared to the saw gin, produced fiber that was more than 1 staple length longer, had two percentage points higher length uniformity, had 2.5 percentage points less short fiber, and contained 25% fewer neps. Yarn (carded and combed) produced from fiber from the roller gin, when compared to fiber from the saw gin, was about 0.2 percentage points more uniform, had 19% fewer thin places, 7.6% fewer thick places, and was 2.4% stronger. The roller gin lots had 30.8% fewer ends down than the saw gin lots when producing fine count combed yarn. Carded and combed yarns produced from the roller gin lots were consistently stronger for a given twist multiple than the saw gin lots, as demonstrated by twist strength curves. Spinning limit trials were conducted that demonstrated carded and combed yarn produced via high-speed roller ginning could be spun faster and into finer counts. The potential economic benefits of processing high-speed roller-ginned upland cotton in a textile mill were explored using data produced in the trials.

Streszczenie:

Toothed gin saws have been used to separate cotton fiber from the seed for more than 200 years. A scientific analysis of saw-tooth design has never been published and the optimum saw-tooth design has not been found. Initial laboratory ginning evaluations of some modern gin saw teeth have shown differences among designs in ginning rate, fiber length measurements, and textile processing quality. The saw gin stand used for testing was a Continental Double Eagle that had been cut down to 46 saws. Four different sets of 16-in diameter, commercially available replacement saws were obtained from independent suppliers. These four sets, along with the standard Continental saw set, were used for five test saw treatments. The test saws varied in the number of teeth per saw from 328 to 352. Testing of the five saw treatments was replicated four times for a total of 20 ginning lots. Each ginning lot was analyzed for raw fiber quality and textile spinning performance. Most of the raw fiber properties were not significantly affected by the saw treatments. However, HVI length and length uniformity after one stage of lint cleaning and seed cotton processing rate were significantly different among saw treatments. The ginning rates varied by 34% from the lowest to the highest at 75% gin stand motor load. The ginned fiber was processed into both open-end and ring-spun yarns. There were few significant differences among saw treatments for the open-end yarn, but there were significant differences for the ring-spun yarn in ends down (a measure of spinning efficiency), yarn evenness, and yarn strength. This indicates that gin saw-tooth design might significantly affect spinning efficiency and yarn quality. Research is currently being done to further understand how gin saw-tooth design affects ginned fiber quality and textile processing quality factors.

Streszczenie:

Cotton fiber was first used in 6000 B.C. The two New World cotton species that are most of today’s production include G. hirsutum (Upland) and G. barbadense (Extra Long Staple [ELS]). The first cotton gin existed by the 5th century A.D (single-roller gin). The next development was the churka gin (double-roller gin) which ginned cotton five times faster than the single-roller gin. The churka gin was widely used in North America by 1750 and ginned both Upland and Sea Island (ELS) cotton. The spike-tooth cotton gin was developed by Eli Whitney in 1794. Hodgen Holmes developed a continuous flow gin with toothed saw blades in 1796. These were a different concept than the double-roller gins. Holmes’ saw gin dominated the industry for Upland cotton (and still does), whereas double-roller gin use continued for Sea Island cotton. In 1840, Fones McCarthy developed a reciprocating-knife roller gin. The saw gin had a significantly higher ginning capacity than the McCarthy gin, so it was used with Upland cotton and the McCarthy roller gin was used with Sea Island cotton to preserve the long-staple cotton’s quality. Sea Island production ceased in 1923 because of the boll weevil, but Pima (ELS) cotton had developed by this time in the Southwest, so roller gin use continued. In 1963, a rotary-knife roller gin was developed that ginned at five times the rate of a reciprocating-knife gin. A high-speed roller gin was developed in 2005 with a ginning capacity, on a per-width basis, comparable to modern-day saw gins.

HighlightsCotton gin saws 0.91 and 1.14 mm thick were compared.Thicker saws had approximately 10% lower processing rate at full motor load.Thicker saws used about 35% more energy to gin the same amount of lint.Abstract. Most cotton fiber (lint) is separated from the seed by gin saw teeth that pull the lint between metal bars (ribs). These ribs are spaced close enough to each other that the seeds cannot pass with the lint. Cotton gin saws are available in three thicknesses, 0.9144, 0.9398, and 1.143 mm (0.036, 0.037, and 0.045 in.). No data from controlled experiments has been published which compares the effect of saw thickness on the economically important performance measures gin processing rate and energy consumption. Two shafts were prepared by installing, at the proper spacing, 406 mm (16 in.) diameter saws of 0.9144 and 1.143 mm thickness for testing on a reduced-width (46-saw) Continental Double Eagle gin stand with constant rib spacing at the USDA-ARS Southwestern Cotton Ginning Research Laboratory in Las Cruces, New Mexico. Energy consumption was recorded for target processing rates 4.88 and 6.08 g saw-1 s-1 using pre-cleaned seed cotton grown in New Mexico, Texas, and Mississippi in a randomized complete block experiment with five replicates. On this equipment we found that the thicker saws averaged 90% (4.69 g saw-1 s-1) the processing rate of the thinner saws (5.21 g saw-1 s-1). Net ginning energy of the 1.143 mm gin saws was 26.5 W-h kg-1 compared to 19.7 W-h kg-1 for the 0.914 mm saws, or about 35% more energy. Results were consistent for cottons from all three regions. Thicker saws are less likely to break under harsh conditions at the ends of the gin stand and are still recommend for use there, but there appears to be no advantage with regard to processing rate or energy use to installing thicker saws across the full width of the gin stand if rib spacing remains unchanged.

HighlightsWe compared 0.91 to 1.14 mm thick gin saws by ginning seed cotton from three regions.The gap between the saw and rib was 0.914 mm for the thin saws and 0.800 mm for the thick ones.Response variables were tested using a sequentially reduced (backwards regression) model.Lint “turnout”, lint value, and seed damage did not appear to be significantly different due to saw thickness.Abstract. Over 95% of U.S. cotton post-harvest processing is done using saw gins. Gin saws have long been supplied in three thicknesses. We quantified the effect of saw thickness on lint turnout, lint value, and seed damage, variables that determine producer returns. Saw cylinders stacked with 0.9144 and 1.143 mm (0.036 and 0.045 in.) thick saws, the thinnest and thickest available, were operated in laboratory conditions on three cotton growths (cultivars and production practices) from Mississippi, New Mexico, and Texas in an experiment with five replicates. Fiber quality from samples obtained after lint cleaning was measured using High Volume Instruments (HVI). HVI results were combined with Commodity Credit Corporation Marketing Assistance Loan premium and discount tables to calculate fiber value. Seed damage was estimated after germination using Association of Official Seed Analysts rules. A backwards regression approach in JMP reduced each response variable’s model until only significant controlled and uncontrolled variables remained. Tested variables included: growth and saw thickness and their interaction; processing rate; processing energy; test duration; foreign matter content; moisture content; and ambient humidity and temperature. There was no significant difference in fiber value due to saw thickness. Seed quality differences were insignificant. Differences in lint turnout due to saw thickness also were statistically insignificant. Saw thickness selection may be based on other considerations.

Roller ginning provided the first mechanical means of separating cotton lint from seed. The first true roller gin was the Churka gin, which produced up to 2.3 kg (5.0 lb) of lint/day. In 1840, the McCarthy gin was invented to gin extra-long-staple (ELS) cotton. Although the ginning capacity of the McCarthy gin was a major improvement over the Churka gin, capacity was limited to about 18 kg (40 lb) of lint per hour. In the late 1950s and early 1960s, a rotary-knife roller gin was developed. The rotary-knife roller gin had a ginning rate 12 times higher than the McCarthy gin, though the rotary knife gin still processed cotton at only about one-fifth the rate of a saw gin with an equivalent width. Around 2005, commercial development of a high-speed rotary-knife roller gin was accomplished. The high-speed roller gin processes cotton at approximately the same rate per unit width as a saw gin. The high-speed roller gin not only allows ELS cotton (such as Pima) to be ginned more efficiently, but also permits high-quality Upland cotton to be roller ginned at a rate more comparable with the saw gin while achieving the benefits of better fiber quality resulting from roller ginning. Although variations of the McCarthy gin are used today in many countries to gin ELS cottons, the rotary-knife roller gin is the only type of roller gin used in the U.S.

Highlights Study included six sample sizes of seed cotton ranging from 0.1 to 1.6 kg. Linear model was a good fit for full range of sample sizes tested. The model showed that energy data is comparable across range of sample sizes tested. More than ginning energy, the ginning time was sensitive to small sample sizes. Abstract. Ginning seed cotton on a 10-saw breeder gin stand with 10-in. saws is often a batch process and there are variables which may affect energy consumption. This study focused on differences in energy consumption of a 10-saw breeder gin stand across five sample sizes of seed cotton ranging from 0.1 to 1.6 kg while also including two sets of saws. An independent t-test found no significant difference in the energy data for similar tests performed on different days, i.e., the conditions under which the test ran did not significantly affect the results. A linear model found evidence that the saw variable and sample size were important to the model. Differences in the model between the saw sets may be due to the surface finish of the saw blade; the geometry of the saw blade may also be important. These results will help to develop guidelines for comparing data across different sample sizes and saw conditions on breeder gin stands.

Streszczenie:

A semiconductor optical source monolithically integrated with a surface acoustic wave (SAW) Bragg-cell to operate as a functional device is proposed in this thesis. The practical structure of such an integrated device is demonstrated and design guidelines are presented. Compared with conventional optical beam processed devices, this functional integrated semiconductor optical source (FISOS) is revised to be compact in size, flexible in function and potentially robust in performance. <br /> The FISOS is analyzed as two sub-divisions, optical source and acoustic processor, which have the common substrate structure. The optical beams excited from the optical source part of the device undergoes a scattering in the Bragg grating formed by SAWs that are generated by an IDT positioned on top of the acoustic processing part of device. By altering the property (power, frequency, etc.) of the SAW, versatile functionalities such as modulation, filtering, beam steering and so on of the optical beams can be realized in this optical source device. <br /> A multilayer structure based on GaN/InGaN MQWs grown on sapphire is designed for the FISOS to be blue light emitting and efficiently launching SAWs. An etch-down technique employed in the SAW processing part is taken to improve the overlap between the optical and acoustic waves and then the interaction efficiency. Optimizations to the geometrical dimensions of the FISOS, such the width of the ridge waveguide, the position of the IDT and the etching depth, etc., are discussed in the given structure. <br /> Numerical models are investigated to access the operational characteristics and then to provide design guidelines for the proposed integrated device. The Bragg diffraction of optical waves occurring within the acoustic waves in the proposed structure are simulated as a two-dimensional interaction between two guided optical modes and an acoustic surface wave. <br /> The modal distributions and propagation velocities of SAWs in a multilayer system are calculated using Adler’s matrix method. The electrical characteristics of an IDT, such as impedance, insertion loss, electromechanical constant and so on are also discussed. <br /> Transverse and lateral optical modes in the given multilayer structure are analyzed by the transfer matrix method. The interaction of optical waves and acoustic waves are modeled using the rigorous grating diffraction theory. Starting from Floquet’s theory, the well-known coupled-wave method and modal method can both be derived from the rigorous grating diffraction theory. Discussions of some useful approximate methods are also presented. In this thesis, the simulations of the acoustooptic interaction are performed using the coupled-wave method. <br /> From the simulation results, the angular distribution profile and spatial profile of the output of the FISOS are evaluated. An improvement to the expression of the diffraction efficiency in such an integrated device is proposed. The so-called beam diffraction efficiency gives a more complete measure to the acoustooptic diffraction and is used to investigate the features of FISOS different from conventional acoustooptic devices. Contour plots of the beam efficiency varying with acoustic frequency and power in a FISOS is demonstrated to be a convenient and powerful approach in the device design. <br /> The operational performances of an integrated deflector and a modulator in FISOS are analyzed to investigate the feasibility of FISOS. The trade-off of the efficiency-resolution in an integrated deflector design is discussed. Short interaction length, high acoustic frequency and narrow ridge are proved to be helpful for a larger number of resolvable spots with a fairly high efficiency. In the case of the integrated modulator, given that the figure of merit Q is fixed, it is demonstrated that the smaller the Q, the longer the interaction length, larger ridge width and lower acoustic frequency will give rise to a larger bandwidth, though the highest efficiency might appear at a higher frequency. <br /> Some practical issues such as the misalignment of planar elements on the device and the incoherence of the integrated optical source are also discussed. A modified working frequency can be used to compensate the efficiency loss in the former case; in the latter case, it is demonstrated that a distortion of beam diffraction efficiency versus acoustic power with an incoherent optical source arises due to the wide spectrum of the incident optical waves.

Pilots or autonomous aircraft need to know where they are in relation to the environment. On board aircraft there are inertial sensors that are prone to drift which requires corrections by referencing against known items, places, or signals. One such method of referencing is with global navigation satellite systems, and others, that are highlighted in this work, are based on using visual sensors. In particular the use of Synthetic Aperture Radar is emerging as a viable alternative. To use radar images in qualitative or quantitative analysis they must be registered with geographical information. Position data on an aircraft or spacecraft is not sufficient to determine with certainty what or where it is one is looking at in a radar image without referencing other images over the same area. It is demonstrated in this thesis that a digital elevation model can be split up and classified into different types of radar scatterers. Different parts of the terrain yielding different types of echoes increases the amount of radar specific characteristics in simulated reference images. This work also presents an interpretation of the imaging geometry of SAR such that existing methods in Computer Vision may be used to estimate the position from which a radar image has been taken. This is a direct image matching without requiring registration that is necessary for other proposals of SAR-based navigation solutions. By determination of position continuously from radar images, aircraft could navigate independently of day light, weather, and satellite data.

A geodatabase and a data management program have been created to store and manipulate cave and karst feature data from the Bahamas. A geographic information system was used to recognize any spatial patterns in the cave and karst data from San Salvador Island. Elevation data for banana holes, vadose pits and flank margin caves were obtained from a digital elevation model and are consistent with values predicted by the Carbonate Island Karst Model. The slope and aspect of the hill on which a flank margin cave is found showed no relationship to cave sizes and shapes, emphasizing the hypogenic nature of flank margin caves. The digital elevation model further demonstrated the position of lakes on San Salvador Island during the last interglacial (OIS 5e) highstand, and the lack of flank margin caves along the shores of these lakes provides evidence for a paleoclimate on San Salvador Island similar to today?s.

San Juan Red Ware was widely distributed throughout the Four Corners region of the U.S. Southwest between about AD 750 and 1100. Prior research indicates this ware is a marker of identity and was likely associated with feasting and other communal activities. A study of the distribution of this ware indicates that it was traded widely, but with significant variation in relative quantity between sites. This variation is likely caused by unequal access to this ware due either to a lack of access to the necessary exchange networks or by a conscious decision to not participate in the exchange of this ware. San Juan Red Ware became more widely dispersed after the first century of production, which may be indicative of increased integration between social groups. Several methods were used in this analysis, including inverse distance weighting, hexagon binning, fall-off curves, distance diagrams using Typenspektren, and social network analysis. An evaluation of these methods indicates some are more effective than others for this analysis, although the use of several complementary methods is recommended to provide a more comprehensive analysis.

Streszczenie:

Morbidity data for chlamydia {CT) and gonorrhea (GC) reported to San Joaquin County (SJC) Department of Health Services (DHS) from 1997 to 2006 was analyzed to geographically locate high risk areas and populations. The largest city in SJC is Stockton, which had the highest incidence rates and highest rates of repeat infections per population, and therefore is the primary focus of this analysis. Rates were determined by dividing the number of infections per census tract by the census 2000 population of each tract. Maps were made first for incidence (cumulative and annual), then for repeat infections, and then coinfections. Census tracts that continually showed high rates of infections were then mapped at the block level to locate more focused areas of infection. Demographic characteristics such as age, gender, race/ethnicity, incarceration, and poverty provided information on the high risk population. Case information was also examined by provider location and the treatment administered. By examining the population characteristics with the highest risk, along with the geographic location, outreach efforts by SJC DHS were far more focused and productive at targeting the core transmissions groups.

Streszczenie:

Hydrological modelling is a powerful tool for hydrologists and engineers involved in the planning and development of integrated approach for the management of water resources. With the recent advent of computational power and the growing availability of spatial data, RS and GIS technologies can augment to a great extent the conventional methods used in rainfall runoff studies; it is possible to accurately describe watershed characteristics in particularly when determining runoff response to rainfall input. The main objective of this study is to apply the potential of spaceborne SAR data for soil moisture retrieval in order to improve the spatial input parameters required for hydrological modelling. For the spatial database creation, high resolution 2 m aerial laser scanning Digital Terrain Model (DTM), soil map, and landuse map were used. Rainfall records were transformed into a runoff through hydrological parameterisation of the watershed and the river network using HEC-HMS software for rainfall runoff simulation. The Soil Conservation Services Curve Number (SCS-CN) and Soil Moisture Accounting (SMA) loss methods were selected to calculate the infiltration losses. In microwave remote sensing, the study of how the microwave interacts with the earth terrain has always been interesting in interpreting the satellite SAR images. In this research soil moisture was derived from two different types of Spaceborne SAR data; TerraSAR-X and ALOS PALSAR (L band). The developed integrated hydrological model was applied to the test site of the Gottleuba Catchment area which covers approximately 400 sqkm, located south of Pirna (Saxony, Germany). To validate the model historical precipitation data of the past ten years were performed. The validated model was further optimized using the extracted soil moisture from SAR data. The simulation results showed a reasonable match between the simulated and the observed hydrographs. Quantitatively the study concluded that based on SAR data, the model could be used as an expeditious tool of soil moisture mapping which required for hydrological modelling.

Streszczenie:

Objective: This paper will focus on reporting the reasons that led one of the biggest medical companies in Latin America to implement a laboratory at Tom Jobim International Airport [Rio de Janeiro’s International Airport (GIG)]. First, a Test Center was designed for processing Covid-19 tests because of its on growing demand by incoming and outgoing passengers. Because of the operation’s positive feedback, the laboratory saw an opportunity to further the development of Test Center. Method: The operation benefited from well-established tools and concepts from the logistics mainly because the field seeks cost-benefit solutions by helping uncovering efficiency gains from the implementation of a risky operation like a clinical lab in an airport. Conclusion: The lab structure at GIG was economically risky, because of the ‘end of the pandemic’ since many countries ended Covid-19 requirements for entrance. Despite this, it was an effective solution for the company’s development beyond Sao Paulo. Its success is due to the adoption of logistics’ concepts also aligned with a contemporary vision. To exemplify, ‘hub’ is a term that can be applied to multiple fields. In logistics, it generally corresponds to a common point for several activities. In our view, various activities like sending out samples of non-routine and special tests were possible because of the existence of our reference lab in Sao Paulo, our focal point. The airport’s strategic location and function – business and transportation focused – were important advantages for the success of the operation. Secondly, the upgrade from a Test Center to a regional lab in Rio de Janeiro allowed the expansion of local services and integration of operations nationwide through the swift delivery and receipt of biological samples to Sao Paulo. As a result, delays were avoided, not compromising the known quality of results offered by the company. Reference: 1. Brigagão PHC. A administração de companhias e a business judgment rule.

Streszczenie:

Two commercial superabsorbent polymer (SAP) formulations were used to internally cure cement pastes, mortars, and concretes with a range of water-to-cement ratios (w/c 0.35–0.52). The following properties were determined as a function of cement chemistry and type, use of chemical admixtures, use of slag, and batching parameters: SAP absorption capacity, fresh mixture workability and consistency, degree of hydration, volumetric stability, cracking tendency, compressive and flexural strength, and pumpability. SAP internal curing agents resulted in cementitious mixtures with improved hydration, accelerated strength gain, greater volumetric stability, and improved cracking resistance while maintaining sufficient workability to be pumped and placed without sacrificing compressive or flexural strength. When using SAP, batching adjustments prioritized the use of water reducing admixture instead of extra water to tune workability. While the benefits of SAP internal curing agents for low w/c mixtures were expected, SAP-containing mixtures with w/c ≥ 0.42 displayed accelerated strength development and decreased cracking tendency.

Artikkelen kritiserer framstillingen av T. Kuhns vitenskapsloso i boka Annerledestenkerne (Universitetsforlaget 2009) av Per Arne Bjørkum. Jeg viser også at de vitenskapshistoriske og biograske opplysningene oftest er mytiske eller feilaktige, og ikke bygger på de mange studier av paradigmeskifter som er publisert etter Kuhns historiske vending. Dermed gir boka heller ikke historisk grunnlag for sin påstand om at forskere som kommer med noe genuint nytt, som regel utsettes for sterkt sosialt press og utstøtelse.

Streszczenie:

In the aerospace industry, competition is high and the need to ensure safety and security while managing costs is paramount. Furthermore, stakeholders—who gain the most by working together—do not necessarily trust each other. Now, mix that with changing enterprise technologies, management of historical records, and customized legacy systems. This issue touches all aspects of the aerospace industry, from frequent flyer miles to aircraft maintenance and drives tremendous inefficiency and cost. Technology that augments, rather than replaces, is needed to transform these complex systems into efficient, digital processes. Blockchain technology offers collaborative opportunities for solving some of the data problems that have long challenged the industry. This SAE EDGE™ Research Report by Rhonda D. Walthall examines how blockchain technology could impact the aerospace industry and addresses some of the unsettled concerns surrounding its implementation.
