Use of Rhea americana egg yolk in substitution to chicken egg yolk in equine semen extenders

Field: Veterinary (Health Sciences)

The aim of this study compared the use of two commercial equine semen extenders supplemented with chicken egg yolk or Rhea americana egg yolk as a lipid source.Ejaculates from six Criollo stallions were visually and microscopically evaluated.Semen samples were divided in two aliquots and diluted in centrifugation extender.Each aliquot was mixed with 2 different commercial semen extenders with chicken or Rhea egg yolk for further cryopreservation.All the thawed samples were checked for total and progressive motility, physical and functional membrane integrity (HOST test and CFDA-PI fluorescence) 1 week or more after cryopreservation.The best results were observed between the commercial semen extenders but there was no strong evidence of Rhea egg yolk to enhance total and progressive sperm motility.However, Rhea egg yolk as an alternative lipid source improved the sperm membrane functionality in both commercial equine semen extenders.The use of Rhea egg yolk might be a good replacement to supplement commercial equine semen extenders.
Advancements in Liquid Jet Technology and X-ray Spectroscopy for Understanding Energy Conversion Materials during Operation

Field: Chemistry (Physical Sciences)

ConspectusWater splitting is intensively studied for sustainable and effective energy storage in green/alternative energy harvesting-storage-release cycles. In this work, we present our recent developments for combining liquid jet microtechnology with different types of soft X-ray spectroscopy at high-flux X-ray sources, in particular developed for studying the oxygen evolution reaction (OER). We are particularly interested in the development of in situ photon-in/photon-out techniques, such as in situ resonant inelastic X-ray scattering (RIXS) techniques at high-repetition-frequency X-ray sources, pointing toward operando capabilities. The pilot catalytic systems we use are perovskites having the general structure ABO3 with lanthanides or group II elements at the A sites and transition metals at the B sites. Depending on the chemical substitutions of ABO3, their catalytic activity for OER can be tuned by varying the composition.In this work, we present our in situ RIXS studies of the manganese L-edge of perovskites during OER. We have developed various X-ray spectroscopy approaches like transmission zone plate-, reflection zone plate-, and grating-based emission spectroscopy techniques. Combined with tunable incident X-ray energies, we yield complementary information about changing (inverse) X-ray absorption features of the perovskites, allowing us to deduce element- and oxidation-state-specific chemical monitoring of the catalyst. Adding liquid jet technology, we monitor element- and oxidation-state-specific interactions of the catalyst with water adsorbate during OER. By comparing the different technical spectroscopy approaches combined with high-repetition-frequency experiments at synchrotrons and free-electron lasers, we conclude that the combination of liquid jet with low-resolution zone-plate-based X-ray spectroscopy is sufficient for element- and oxidation-state-specific chemical monitoring during OER and easy to handle.For an in-depth study of OER mechanisms, however, including the characterization of catalyst-water adsorbate in terms of their charge transfer properties and especially valence intermediates formed during OER, high-resolution spectroscopy tools based on a combination of liquid jets with gratings bear bigger potential since they allow resolution of otherwise-overlapping X-ray spectroscopy transitions. Common for all of these experimental approaches is the conclusion that without the versatile developments of liquid jets and liquid beam technologies, elaborate experiments such as high-repetition experiments at high-flux X-ray sources (like synchrotrons or free-electron lasers) would hardly be possible. Such experiments allow sample refreshment for every single X-ray shot for repetition frequencies of up to 5 MHz, so that it is possible (a) to study X-ray-radiation-sensitive samples and also (b) to utilize novel types of flux-hungry X-ray spectroscopy tools like photon-in/photon-out X-ray spectroscopy to study the OER.

Back Mixing Effects in Flotation Banks

Field: Chemical Engineering (Physical Sciences)

The modern trend in industrial flotation technology is towards larger cells arranged in open flow banks. While such installations are undoubtedly cheaper to install, back-mixing within these banks can severely limit plant performance. Tracer experiments conducted at two industrial concentrators revealed the presence of considerable back-mixing in such equipment; the reverse flow was found to be up to seven times the net forward flow. Calculations show that this inefficiency results in significant decreases in bank recovery and concentrate grade.

Inhalation Tests of Bronchial Hypersensitivity in Pollen Asthma

Field: Medicine (Health Sciences)

Possible allergic causes of asthma are frequently investigated by determining the sensitivity of the skin to various extracts of potentially allergenic substances, but the results of skin tests may correlate poorly with other clinical indications of specific allergies. Bronchial sensitivity cannot always be inferred from skin sensitivity. Determination of the response of the bronchi to allergens introduced directly into the respiratory tract seems to be a more direct method of testing for allergic causes of asthma, since it tests the hypersensitivity of the bronchial tree which is responsible for the symptoms in asthma and simulates the usual mode of entry of the allergen as it occurs in asthma. Inhalations of allergens were found by Colldahl (1952) to produce wheezing, evident to the subject or to observers, in some asthmatics, and by Herschfus, Rubitsky, Beakey, Bresnick, Levinson, and Segal (1951), Schiller and Lowell (1952) and Herxheimer (1952) to produce changes in the spirogram. The object of this investigation was to try out inhalation tests of bronchial hypersensitivity and to determine whether they give results which are reliable, consistent, and specific. For this purpose we selected patients in whom asthma was strictly seasonal and clinically appeared to be due only to grass pollen. We gave them inhalations of grass pollen extract and assessed the bronchial response by spirometry, and studied the effect upon this response of pollen hyposensitization treatment.

Synthesis and evaluation of nitrogen-containing derivatives of 3,11-dioxo-olean-12-en-30-oic acid against HIV-1 protease

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Thirteen nitrogen-containing derivatives of 3,11-dioxo-olean-12-en-30-oic acid were synthesised by introducing various amino acids and nitrogen-containing heterocyclic groups at the 30-carboxyl group, starting from 18β-glycyrrhetinic acid. Among the 13 derivatives, 10 exhibited inhibitory activity against HIV-1 PR, with IC50 values ranging from 0.19 to 0.94 mM. Notably, derivatives 2, 3 and 5 displayed relatively moderate inhibitory activity, with IC50 values below 0.24 mM. Molecular docking studies provided further insights into the interaction between derivatives (2, 3 and 5) and the active sites of HIV-1 PR. The results revealed favourable hydrophobic-hydrophobic and hydrogen bonding interactions, with docking scores ranging from −6.22 to −7.00 and glide emodel values from −62.9 to −48.6 (kcal/mol). These findings underscore the potential of derivatives 2, 3 and 5 as promising candidates for the development of HIV-1 PR inhibitors.
Time-Constrained Sequential Pattern Mining

Field: Computer Science (Physical Sciences)

Sequential pattern mining is one of the important issues in the research of data mining (Agrawal & Srikant, 1995; Ayres, Gehrke, & Yiu, 2002; Han, Pei, & Yan, 2004; Lin & Lee, 2004; Lin & Lee, 2005b; Roddick & Spiliopoulou, 2002). A typical example is a retail database where each record corresponds to a customer’s purchasing sequence, called data sequence. A data sequence is composed of all the customer’s transactions ordered by transaction time. Each transaction is represented by a set of literals indicating the set of items (called itemset) purchased in the transaction. The objective is to find all the frequent sub-sequences (called sequential patterns) in the sequence database. Whether a sub-sequence is frequent or not is determined by its frequency, named support, in the sequence database. An example sequential pattern might be that 40% customers bought PC and printer, followed by the purchase of scanner and graphics-software, and then digital camera. Such a pattern, denoted by , has three elements where each element is an itemset. Although the issue is motivated by the retail industry, the mining technique is applicable to domains bearing sequence characteristics, including the analysis of Web traversal patterns, medical treatments, natural disasters, DNA sequences, and so forth. In order to have more accurate results, constraints in addition to the support threshold need to be specified in the mining (Pei, Han, & Wang, 2007; Chen & Yu, 2006; Garofalakis, Rastogi, & Shim, 2002; Lin & Lee, 2005a; Masseglia, Poncelet, & Teisseire, 2004). Most time-independent constraints can be handled, without modifying the fundamental mining algorithm, by a postprocessing on the result of sequential pattern mining without constraints. Time-constraints, however, cannot be managed by retrieving patterns because the support computation of patterns must validate the time attributes for every data sequence in the mining process. Therefore, time-constrained sequential pattern mining (Lin & Lee, 2005a; Lin, Hsueh, & Chang, 2006; Masseglia, Poncelet, & Teisseire, 2004;) is more challenging, and more important in the aspect of temporal relationship discovery, than conventional pattern mining.

The final design of Flux has changed dramatically from what was presented in the initial concept in terms of form, ideas, function and inspiration. However the main concept of Flux has remained, that is the fluid circulation of people in and around structures. Flux has now been redesigned primarily as a train station with its secondary function being a shopping complex. This is an insurance of a constant flow of people. The irregularity of the initial form has been replaced with blocks that have been influenced by the frames of basic comic book pages. The methods of visual flow, which the comic book artist creates in his pages, have been a huge influence to Flux. Not only do they provide cultural relevance to New York, but they also provided the ideas behind the circulation in Flux. This has allowed for a dramatic increase in circulation and functional space. The new form is a logical change. The train station is five floors, which is made up of three retail floors, a station terminal, and underground platforms. The retail floors are connected to the secondary towers through a collection of sky bridges allowing for easy and fluid access. The terminal is accessible from both sides of the street for the convenience of commuters and for logical circulation. The platforms are sealed with glass barriers that open when trains arrive, the strength of this lies in the comfort and safety of commuters. The secondary towers that site adjacent to the station are six and four floors each. They are solely retail spaces and each have a circulatory halve. The six-floor building leans in towards the plaza between the three structures. This plaza is designed to accommodate functions and events such as night markets, political rallies, busking space and for general relaxation.
Fatigue Crack Growth Monitoring and Investigation on G20Mn5QT Cast Steel and Welds via Acoustic Emission

Field: Engineering (Physical Sciences)

The fatigue crack growth properties of G20Mn5QT cast steel and corresponding butt welds, using compact tension specimens, were monitored and investigated via acoustic emission (AE) techniques. Fatigue crack growth is a combination of cyclic plastic deformations before the crack tip, tensile crack fractures, and shear crack fractures. The cyclic plastic deformations release the maximum amount of energy, which accounts for half of the total energy, and the second-largest number of AE signals, which are of the continuous-wave type. The tensile crack fractures release the second-largest amount of energy and the largest number of AE signals, which are of the burst-wave type. The shear crack fractures release the least amount of energy and the lowest number of AE signals, which are similar to the burst type, albeit with a relatively longer rise time and duration. Crack tip advancement can be regarded as a discontinuous process. The critical area before the crack tip brittlely ruptures when the fatigue damage caused by cyclic plastic deformations reaches critical status. The ruptures produce a large number of tensile crack fractures and rare shear crack fractures. Through fractography observation, the shear crack fractures occur probabilistically around defects caused by casting or welding, which lead to stress and strain in the local complex.
Early Labor Market Experiences of Youth and Subsequent Wages

Field: Economics, Econometrics and Finance (Social Sciences)

A bstract . High youth unemployment continues to be a major concern to policymakers in the United States. In view of the many studies that have documented a perpetuation of the relatively high jobless rates for youth in the postwar period whether disaggregated by age, sex , or race , the debate on the youth employment‐unemployment problem has begun to focus more recently on its socioeconomic consequences. One of the overriding concerns is that early labor market unemployment experiences might carry over into later labor force performance. The cumulative effects of prolonged periods of unemployment and intermittent unemployment (i.e. , duration and spells of unemployment) on the subsequent wages of a cohort of young men are examined. Spells of unemployment experienced early in the labor market careers of the cohort tended to have an increasing effect on their later wages , while spells occurring later and the duration of unemployment then serve to lower their subsequent wages.

A Case of Engineering Quality for Mobile Healthcare Applications Using Augmented Personal Software Process Improvement

Field: Computer Science (Physical Sciences)

Mobile healthcare systems are currently considered as key research areas in the domain of software engineering. The adoption of modern technologies, for mobile healthcare systems, is a quick option for industry professionals. Software architecture is a key feature that contributes towards a software product, solution, or services. Software architecture helps in better communication, documentation of design decisions, risks identification, basis for reusability, scalability, scheduling, and reduced maintenance cost and lastly it helps to avoid software failures. Hence, in order to solve the abovementioned issues in mobile healthcare, the software architecture is integrated with personal software process. Personal software process has been applied successfully but it is unable to address the issues related to architectural design and evaluation capabilities. Hence, a new technique architecture augmented personal process is presented in order to enhance the quality of the mobile healthcare systems through the use of architectural design with integration of personal software process. The proposed process was validated by case studies. It was found that the proposed process helped in reducing the overall costs and effort. Moreover, an improved architectural design helped in development of high quality mobile healthcare system.
