Synthesis of Tricholomic Acid. IV. Synthesis of DL-threo-α-Amino-3-oxo-5-isoxazolidineacetic Acid (1969)

DL-threo-α-Amino-3-oxo-5-isoxazolidineacetic acid, an isomer of tricholomic acid, was synthesized in a 3-step sequence starting from dialkyl N-acyl-β-chloroglutamate. Several isolations have been attempted to separate the threo- and erythro-isomers from their mixture. The threo-isomer was devoid of good taste and flycidal activity which are characteristic of the erythro-isomer.
Computer Vision System Based for Personal Protective Equipment Detection, by Using Convolutional Neural Network (2019)

The number of work accidents happened in Indonesia does not decrease, in this moment. One of the cause of work accidents is human negligence in wearing personal protective equipment or what is called PPE. A system that can monitor the completeness of PPE worn by workers in an industrial environment automatically is needed. Computer vision technology one method known as convolutional neural network is used, this is a system to monitor directly and detect workers who do not wear PPE. The level system precision have seen by compare between the real condition and the system condition red which is shown the people without PPE completely. The resulted of the system resulted would compare with the examiner's. The result shown that this system is able to know and distinguish between workers who wear PPE in full and not. With the number of dataset 14512 images, the accuracy of this system is 79.14% with the precision of the detection resulted 80%. This system can give a warning if there are workers who do not wear PPE completely and also could be implemented into several workplaces that have the requirements for the detection. This system give the contribution to decrease work accidents and to increase the safeness of the workers.
Spectrum analysis of cardiovascular time series (1997)

The demand for noninvasive assessment of cardiovascular control parameters has promoted the use of spectrum analysis. These techniques have been applied on a broad basis; however, because of the abstract mathematical approach, spectrum analysis in physiology is still not fully accepted by some circles in the scientific community. Thus it is the goal of the following review to focus on the rationale for applying spectrum analysis in different fields of circulation research, which range from determining arterial baroreceptor reflex sensitivity to the early detection of heart allograft rejection. Within this scope, major findings regarding the physiological and pathophysiological regulation of the cardiovascular system are discussed. In addition, inherent limitations of these methods are made clear. Toward the end of this survey, a perspective is provided for the general readership.
Truck Routing Issues (2017)

Abstract: Commercial vehicle drivers selecting inappropriate routes where the handling characteristics (e.g., off-tracking) and dimensions of their trucks are not consistent with a roadway’s cross section and geometrics can damage the vehicle, harm adjacent property, or result in crashes. Analysis of crashes that involve the use of inappropriate routes indicate a significant number are caused by drivers receiving faulty directions from in-truck GPS units or adhering to incorrect directions provided by their companies. The Kentucky Transportation Center (KTC) investigated strategies to ensure truck drivers are given correct directions when traveling on Kentucky roadways. As part of this effort, this report reviews policies and regulations adopted by other states to ensure trucks have the proper grade GPS units. It also catalogues crashes that have occurred in the state of Kentucky where errant GPS directions contributed to incidents and highlights corrective actions that have been taken (e.g., installation of signage) to warn truck drivers of route restrictions or adverse conditions. Based on a review of incidents and case studies, the report presents recommendations to ameliorate the problem of truck drivers selecting inappropriate routes. Key suggestions include: requiring commercial vehicles to have GPS units designed specifically for truck routing; installing truck routing signs consistent with standards laid out in the Manual on Uniform Traffic Control Devices; installing warning signs in advance of low clearance bridges, low ground clearance railroad crossings, and weight-restricted routes; improving driver training on GPS systems and enhancing communication between drivers and trucking companies; and forging collaborative agreements between transportation agencies and mapping companies to ensure mapping products incorporate correct routing information.

Synthesis of functional TiO2-based nanoparticles in radio frequency induction thermal plasma (2008)

Abstract A method of synthesizing functional nanostructured powders by using reactive thermal plasma processing has been developed. Nanosized TiO 2 powders have been synthesized by the plasma oxidation of solid and liquid precursors. Quench gases, either injected from the shoulder of the reactor or injected counter to the plasma plume from the bottom of the reactor, are used to affect the quench rate and hence the particle size of the resultant powders. The experimental results are well supported by numerical analysis of the effects of the quench gas on flow pattern and temperature field of the thermal plasma as well as trajectory and temperature histories of the particles. The plasma-synthesized TiO 2 nanoparticles showed phase preferences different from those synthesized by conventional wet processes. Nanosized particles of high crystallinity and nonequilibrium chemical composition were formed in one step by reactive thermal plasma processing. The plasma-synthesized nanoparticles were spherical and hardly agglomerated. Applications of highly functional nanoparticles are thought to require nanoparticles structured in the forms of (1) dispersoids, (2) fillers, and (3) patterns. For these purposes, plasma-synthesized nanocrystallites seem to be suitable.
Polaron absorption in amorphous tungsten oxide films (2001)

Amorphous thin films of tungsten oxide were deposited by sputtering onto glass substrates covered by conductive indium–tin oxide. The density and stoichiometry were determined by Rutherford backscattering spectrometry. Lithium ions were intercalated electrochemically into the films. The optical reflectance and transmittance were measured in the wavelength range from 0.3 to 2.5 μm, at a number of intercalation levels. The polaron absorption peak becomes more symmetric and shifts to higher energies until an intercalation level of 0.25 to 0.3 Li+/W, where a saturation occurs. The shape of the polaron peak is in very good agreement with the theory of Bryksin [Fiz. Tverd. Tela 24, 1110 (1982)]. Within this model, the shift of the absorption peak is interpreted as an increase in the Fermi level of the material as more Li ions are inserted.
Synthesis of 3-deazathiamine (2001)

An efficient ten-step synthesis of deazathiamine is described. The synthesis starts from commercially available α-acetyl-γ-butyrolactone and proceeds via deamination of the key aminothiophene 6. The Gewald synthesis of thiophenes is shown to give a mixture of isomeric products with the unsymmetric ketone used here and so a modified procedure giving a single isomer is developed.
A PROTOTYPE DAB RECEIVER (2005)

A prototype Digital Audio Broadcasting (DAB) receiver has been developed. This receiver can decode the DAB signal based on the EUREKA 147 third generation format. The performance of this receiver has been evaluated through laboratory tests and field tests.
Strained Silacycles in Organic Synthesis:  A New Reagent for the Enantioselective Allylation of Aldehydes (2002)

A new reagent for the enantioselective allylation of aliphatic aldehydes has been developed. The reagent is easily prepared in a single step from commercially available materials and may be stored without significant decomposition. The reactivity of the reagent is attributed to strain-release Lewis acidity.
A fast method for single image dehazing using dark channel prior (2014)

In this paper, we propose an improved method for single image haze removal based on the dark channel prior. The dark channel prior is a kind of statistics of outdoor haze-free images. It estimates the transmission map and gives out a superior result. While refining the transmission map with soft matting is computation consuming and this prior is invalid for near white scenes. We simplify the refining step by locally processing and the region to be refined is located by dealing with the coarse dark channel. By computing the difference of intensities between the highest channel and the lowest, we reestimate the transmission map with a method derived from underwater dehazing. Results show that our method has a good ability of haze removal with lower computation and the output of near white scenes is more realistic.
Assessment of Aerobic and Respiratory Growth in the Lactobacillus casei Group (2014)

One hundred eighty four strains belonging to the species Lactobacillus casei, L. paracasei and L. rhamnosus were screened for their ability to grow under aerobic conditions, in media containing heme and menaquinone and/or compounds generating reactive oxygen species (ROS), in order to identify respiratory and oxygen-tolerant phenotypes. Most strains were able to cope with aerobic conditions and for many strains aerobic growth and heme or heme/menaquinone supplementation increased biomass production compared to anaerobic cultivation. Only four L. casei strains showed a catalase-like activity under anaerobic, aerobic and respiratory conditions and were able to survive in presence of H2O2 (1 mM). Almost all L. casei and L. paracasei strains tolerated menadione (0.2 mM) and most tolerated pyrogallol (50 mM), while L. rhamnosus was usually resistant only to the latter compound. This is the first study in which an extensive screening of oxygen and oxidative stress tolerance of members of the L. casei group has been carried out. Results allowed the selection of strains showing the typical traits of aerobic and respiratory metabolism (increased pH and biomass under aerobic or respiratory conditions) and unique oxidative stress response properties. Aerobic growth and respiration may confer technological and physiological advantages in the L. casei group and oxygen-tolerant phenotypes could be exploited in several food industry applications.
Web API protocol and security analysis (2017)

There is problem that every company has its own customer portal. This problem can be solved by creating a platform that gathers all customers’ portals in one place. For such platform, it is required a web API protocol that is fast, secure and has capacity for many users. Consequently, a survey of various web API protocols has been made by testing their performance and security. The task was to find out which web API protocol offered high security as well as high performance in terms of response time both at low and high load. This included an investigation of previous work to find out if certain protocols could be ruled out. During the work, the platform’s backend was also developed, which needed to implement chosen web API protocols that would later be tested. The performed tests measured the APIs’ connection time and their response time with and without load. The results were analyzed and showed that the protocols had both pros and cons. Finally, a protocol was chosen that was suitable for the platform because it offered high security and fast connection. In addition, the server was not affected negatively by the number of connections. Reactive REST was the web API protocol chosen for this platform.
Dependence of non‐adrenergic inhibition of cardiac vagal action on peak frequency of sympathetic stimulation in the dog. (1988)

1. It is known that stimulation of the sympathetic cardioaccelerator nerve is followed by prolonged inhibition of cardiac vagal action. This prolonged inhibitory action of the sympathetic nerve is not blocked by alpha- or beta-adrenoceptor blockade, and is not duplicated by administration of noradrenaline. It has been proposed that it is due to the release of neuropeptide Y (NPY) from the sympathetic nerve terminals (Potter, 1984, 1985). 2. The present experiments examined whether prolonged inhibition of cardiac vagal action could be preferentially produced by sympathetic stimulation of different temporal distribution. The experiments were performed on anaesthetized, vagotomized dogs, with pharmacological beta-adrenoceptor blockade. 3. In six animals intermittent supramaximal sympathetic stimulation at 20 Hz (1/2 s stimulation, 1/2 s off; train duration 2 min; total 1200 stimuli) produced significantly greater inhibition (P less than 0.01) of cardiac vagal action than did continuous stimulation at 5 Hz (stimulus duration 4 min; 1200 stimuli). 4. In another series the same total period of stimulation (2.5 min; 1200 stimuli) was used and it was found that intermittent sympathetic stimulation of 16 Hz (1/2 s stimulation, 1/2 s off) produced significantly greater cardiac vagal inhibition (P less than 0.02) than continuous stimulation at 8 Hz. In this case the mean frequency of stimulation was constant but the higher peak stimulation frequency attenuated cardiac vagal action more effectively.

Hermetic Coating On Optical Fibers (1987)

Mechanical failure of optical fibers under stress over extended period of time is caused by static fatigue of fibers. To ensure long term reliability, a method of mini-mizing the static fatigue phenomenon in optical fibers is necessary. Potential solution is to put an impervious hermetic coating around the optical fiber so that diffusion of moisture to glass can be arrested. A technique for putting such a hermetic coating on optical fiber is chemical vapor deposition. Performance results of optical fibers coated with several different materials are presented.
Virtual population‐based assessment of the impact of 3 Tesla radiofrequency shimming and thermoregulation on safety and B<sub>1</sub>+ uniformity (2015)

Image quality with 3T body coils can be significantly increased by RF shimming. Exposure in realistic scan scenarios within guideline limits can be considered safe for a broad patient population with normal thermoregulation. Patients with impaired thermoregulation should not be scanned outside of the normal operating mode. Magn Reson Med 76:986-997, 2016. © 2015 Wiley Periodicals, Inc.
Evidence for metastatic heterogeneity of human renal cell carcinoma. (1989)

We determined whether human renal cell carcinoma (HRCC) is heterogeneous and contains cells with different metastatic properties. The parental SN12C line was established in culture from a surgical specimen of HRCC. Clonal populations of cells were isolated by a double-dilution technique. Cells from parental and 11 clonal lines were injected subcutaneously, intravenously, and into the renal subcapsule of nude mice. Seven of the 11 cloned lines differed significantly from the parent line in their ability to produce pulmonary metastases after renal subcapsule injection. These results indicate that this HRCC is heterogeneous for metastasis, and that the outcome of metastasis in nude mice is influenced by the site of implantation.

Reconfigurable computing: is it ready for industry (2005)

For a relatively long time, reconfigurable computing (RC) has been a thriving area of academic research. An indication of success is the commercialization of the technology. Is RC ready for such commercialization? what application domains is it targeting? Is it going to be a disruptive or evolutionary technology? This paper surveys some of the RC technologies in the commercial domain and shed some light on its target applications.
Development of a new photocatalytic oxidation air filter for aircraft cabin (2005)

The VOC/odor removing adsorbers are available for only a small proportion of aircraft currently in service. The photocatalytic oxidation (PCO) technique has appeared to be a promising solution to odors problems met in aircraft. This article reports the test results of a new photocatalytic oxidation air filter (PCO unit) designed for aircraft cabin applications. The overall efficiency of the PCO unit is function of the compound (toluene, ethanol, and acetone) that challenges the unit and toluene appears to be the most difficult compound to oxidize. Test results have shown the influence of the design of the PCO unit, the air flow rate and the type of UV on the efficiency of the PCO unit. The results obtained in this study represent a first attempt on the way to design a filter for VOC removal in cabin aircraft applications. The PCO technique used by the tested prototype unit is able to partially oxidized the challenge VOCs but one has to be aware that some harmful intermediate reaction products (mainly formaldehyde and acetaldehyde) are produced during the oxidation process before being partially oxidized too.
Transcriptional Control of Early B Cell Development (2004)

The generation of B-lymphocytes from hematopoietic stem cells is controlled by multiple transcription factors regulating distinct developmental aspects. Ikaros and PU.1 act in parallel pathways to control the development of lymphoid progenitors in part by regulating the expression of essential signaling receptors (Flt3, c-Kit, and IL-7R alpha). The generation of the earliest B cell progenitors depends on E2A and EBF, which coordinately activate the B cell gene expression program and immunoglobulin heavy-chain gene rearrangements at the onset of B-lymphopoiesis. Pax5 restricts the developmental options of lymphoid progenitors to the B cell lineage by repressing the transcription of lineage-inappropriate genes and simultaneously activating the expression of B-lymphoid signaling molecules. LEF1 and Sox4 contribute to the survival and proliferation of pro-B cells in response to extracellular signals. Finally, IRF4 and IRF8 together control the termination of pre-B cell receptor signaling and thus promote differentiation to small pre-B cells undergoing light-chain gene rearrangements.
Effect of Redox Conditions on MTBE Biodegradation in Surface Water Sediments (2001)

Microbial degradation of methyl tert-butyl ether (MTBE) was observed in surface water-sediment microcosms under anaerobic conditions. The efficiency and products of anaerobic MTBE biodegradation were dependent on the predominant terminal electron-accepting conditions. In the presence of substantial methanogenic activity, MTBE biodegradation was nominal and involved reduction of MTBE to the toxic product, tert-butyl alcohol (TBA). In the absence of significant methanogenic activity, accumulation of [14C]TBA generally decreased, and mineralization of [U-14C]MTBE to 14CO2 generally increased as the oxidative potential of the predominant terminal electron acceptor increased in the order of SO4, Fe(III), Mn(IV) < NO3 < O2. Microbial mineralization of MTBE to CO2 under Mn(IV)-or SO4-reducing conditions has not been reported previously. The results of this study indicate that microorganisms inhabiting the sediments of streams and lakes can degrade MTBE effectively under a range of anaerobic terminal electron-accepting conditions. Thus, anaerobic bed sediment microbial processes may provide a significant environmental sink for MTBE in surface water systems throughout the United States.
Experimental infection and immune response of guinea pigs with varicella-zoster virus (1982)

An immune response (fluorescent antibody to membrane antigen) was detected in guinea pigs inoculated with varicella-zoster virus (VZV) adapted to guinea pig embryonic cells, including the Oka vaccine strain, even when inoculation was by an external route, i.e., nasal or corneal. Live or UV-inactivated virus having the same virus titer before irradiation was administered to guinea pigs by the corneal route, and antibody induction was detected only with live virus. The transmission of VZV from infected guinea pigs to noninfected ones was suggested by the appearance of antibody in the serum of the latter, who were kept in the same cage. The time course of the appearance of humoral and cellular immune responses in guinea pigs was examined by the fluorescent antibody to membrane antigen test and the skin reaction, with varicella antigen representing delayed-type hypersensitivity. When VZV was injected subcutaneously, skin reaction appeared as early as 4 days after inoculation, which preceded the appearance of detectable antibody by 2 to 6 days. In in vitro studies, the Oka vaccine showed a higher adsorption rate and better growth in guinea pig embryonic cells than did other wild-type strains when assayed by the infectious center assay. These results suggest that a system of VZV adapted to guinea pig cells and guinea pigs provides a good animal experimental model for immunological study of VZV infection.
Temozolomide stability in extemporaneously compounded oral suspensions. (2015)

Temozolomide, commercially available in capsules, is an oral alkylating agent used to treat brain tumors. The purpose of this study was to determine the pharmaceutical acceptability and chemical stability of temozolomide in two extemporaneously compounded suspension formulations prepared from the capsules. The temozolomide oral suspensions were prepared from 100-mg commercial capsules yielding a nominal temozolomide concentration of 10 mg/mL. The suspension vehicles selected for testing were an equal parts mixture of Ora-Plus and Ora-Sweet and an equal parts mixture of Ora-Plus and Ora-Sweet SF. The suspensions were packaged in amber plastic screw-cap prescription bottles, which were stored at 23 deg C for 21 days or 4 deg C for 60 days. Stability-indicating high-performance liquid chromatographic analysis revealed that the temozolomide concentration in both suspension vehicle combinations exhibited little or no loss for 60 days at 4 deg C. At 23 deg C, temozolomide losses were somewhat greater. In the Ora-Sweet formulation, the loss was 6% at 7 days; in the Ora-Sweet SF formulation, losses were about 8% at 14 days and 10% to 11% at 21 days. Temozolomide extemporaneously prepared as oral suspensions from capsules in equal parts mixtures of Ora-Plus suspension vehicle with Ora-Sweet and with ora-Sweet SF syrups with added povidine k-30 and acidified with citric acid were pharmaceutically acceptable and chemically stable for at least 60 days at 4 deg C. Refrigerated storage is recommended. The suspensions should not be stored at room temperature longer than 1 week if Ora-Sweet is used or longer than 2 weeks if Ora-Sweet SF is used.
