The usability of (sodium alginate/acrylamide) semi‐interpenetrating polymer networks on removal of some textile dyes (2008)

Abstract In this study, (sodium alginate/acrylamide) interpenetrating polymer networks ((NaAlg/AAm)IPN) have been prepared at definite composition. The aqueous solution of 3% (w/v) sodium alginate and 50% (w/v) acrylamide was irradiated with 60 Co‐γ rays at a dose rate of 0.07 kGy/h up to 5 kGy. The percent conversion was determined gravimetrically and 100% gelation was achieved at 5 kGy dose. To understand whether the semi‐interpenetrating polymer network of sodium alginate is performed, Fourier Transform Infrared (FTIR) spectra of polyacrylamide (PAAm), sodium alginate, and the semi‐interpenetrating polymer network were recorded. It is found that the FTIR spectra of PAAm, NaAlg, and the semi‐interpenetrating polymer network are different. The thermograms of PAAm, sodium alginate, and the semi‐interpenetrating polymer network were recorded for investigating their thermal character. (NaAlg/AAm)IPN hydrogels were immersed to swell in a solution of pH 7, at a temperature of 25°C. The swelling results at pH 7.0 indicated that (NaAlg/AAm)IPN hydrogel, containing 3% NaAlg showed maximum % swelling in water but swelling increased in the order of water > Magenta > Methylene Blue > Safranine‐O > Methyl Violet. Diffusion of water and aqueous solution of dyes within (NaAlg/AAm)IPN hydrogels was found to be of Fickian character at the initial stage of swelling with regard to values calculated for diffusion coefficient of (NaAlg/AAm)IPN hydrogels in water and aqueous solution of dyes. Some diffusion parameters were calculated from swelling of (NaAlg/AAm)IPN in water and dyes and their adsorption isotherms were plotted. In the adsorption experiments, the efficiency of (NaAlg/AAm)IPN hydrogels to adsorb Magenta, Safranine‐O, Methylene Blue, and Methyl Violet dyes from water was studied. (NaAlg/AAm)IPN hydrogels showed different adsorption for different aqueous solution of dyes at pH 7.0. Adsorption isotherms were constructed for (NaAlg/AAm)IPN‐dye systems. S type adsorption in the Giles classification system was found. Thermal and spectroscopic characterization of semi‐interpenetrating polymer network of sodium alginate and acrylamide and dye adsorbed semi‐interpenetrating polymer network of sodium alginate and acrylamide was recorded. © 2008 Wiley Periodicals, Inc.

Frame Rate Up-Conversion Using Trilateral Filtering (2010)

Frame rate up-conversion (FRUC) can enhance the visual quality of low frame rate video presented on liquid crystal display. To minimize the difference between a reference block and an interpolated block, an effective FRUC algorithm partitions a large block into several sub-blocks of smaller size and estimates their motions. Motion estimation searches for the block which has the minimum difference (cost) with the processed block in terms of some block matching distortion and motion discontinuity. As convexity and convergence of the cost function are not guaranteed, the computational cost for such motion estimation is usually extensive or unpredictable. In our proposed FRUC method, the two predictions of a frame to be interpolated are generated through shifting its nearest neighbor frames in the previous and following directions with the motion vectors estimated between them. The initial interpolated frame and its pixel's reliability are subsequently estimated from these two predictions. We then apply a trilateral filter on the initial prediction to correct the unreliable pixels and to restore the missing pixels. Our proposed method not only reduces the computation for refining motion vectors, but also suppresses the interpolation noises and misregistration errors. We have conducted extensive experiments and the results show that the proposed algorithm outperforms the existing methods with better objective and subjective visual quality, and achieves about 3 dB on-average peak signal-to-noise ratio improvement.
Tumor Grafting Induces Changes of Gut Microbiota in Athymic Nude Mice in the Presence and Absence of Medicinal Gynostemma Saponins (2015)

Recent findings have revealed that gut microbiota plays a substantial role in modulating diseases such as autism, rheumatoid arthritis, allergies, and cancer that occur at sites distant to the gut. Athymic nude mice have been employed for tumorigenic research for decades; however, the relationships between the gut microbiome and host's response in drug treatment to the grafted tumors have not been explored. In this study, we analyzed the fecal microbiome of nonxenograft and xenograft nude mice treated with phytosaponins from a popular medicinal plant, Gynostemma pentaphyllum (Gp). Analysis of enterobacterial repetitive intergenic consensus (ERIC)-PCR data showed that the microbiota profile of xenograft mice departed from that of the nonxenograft mice. After ten days of treatment with Gp saponins (GpS), the microbiota of the treated mice was closer to the microbiota at Day 0 before the implantation of the tumor. Data obtained from 16S pyrosequencing of fecal samples reiterates the differences in microbiome between the nonxenograft and xenograft mice. GpS markedly increased the relative abundance of Clostridium cocleatum and Bacteroides acidifaciens, for which the beneficial effects on the host have been well documented. This study, for the first time, characterizes the properties of gut microbiome in nude mice responding to tumor implant and drug treatment. We also demonstrate that dietary saponins such as GpS can potentially regulate the gut microbial ecosystem by increasing the number of symbionts. Interestingly, this regulation of the gut ecosystem might, at least in part, be responsible for or contribute to the anticancer effect of GpS.
Ultraviolet radiation from the pulsed corona discharge in water (2008)

Quantitative analysis of ultraviolet radiation from the pulsed corona discharge in water with needle-plate electrode geometry (∼1–3 J pulse−1) was performed using the potassium ferrioxalate actinometry. Photon flux J190–280 and radiant energy Q190–280 of the UV light emitted from the discharge at spectral region 190–280 nm was determined in dependence on the applied voltage (17–29 kV, positive polarity) and the solution conductivity (100–500 µS cm−1). The intensity of the UV radiation strongly increased with increasing water conductivity and applied voltage. Depending on the applied voltage the determined photon flux varied by more than two orders of magnitude within the range of solution conductivities 100–500 µS cm−1. It was found that photon flux from the discharge may be directly related to the discharge pulse mean power Pp as J190–280 = 44.33 (quanta pulse−1). A significant role of UV radiation in the production of hydrogen peroxide and bacterial inactivation by the corona discharge in water has been identified. As the solution conductivity increased the yield of H2O2 produced by the discharge decreased due to increasing photolysis of H2O2 accounting for up to 14% of the total decomposition rate of H2O2. As regards bactericidal effects, it was estimated that the UV radiation contributes about 30% to the overall inactivation of Escherichia coli.

Permanent Partial Disability Awards and Wage Loss (2000)

Physicians handling workers compensation cases serve in a dual not required of physicians treating non-workers compensation cases. Not only are they are asked to treat the workers' injuries and disability symptoms, but they are also frequently asked to evaluate the extent of economic damage done to a worker via the assignment of an impairment rating to certain types of injuries. Although physicians are trained to treat traumatic injuries as well as the symptoms of cumulative trauma processes, they generally receive no training in disability evaluation. The authors examine physicians' ability to carry out their latter, lost earnings capacity assessment, role. Their multivariate regressions indicate that physicians' impairment ratings are poor guides to subsequent wage loss; impairment ratings explain no more than one-half of 1 percent of subsequent wage loss.
Effects of novobiocin, coumermycin A1, clorobiocin, and their analogs on Escherichia coli DNA gyrase and bacterial growth (1982)

Novobiocin, coumermycin A1, and clorobiocin, structurally related compounds that antagonize the B subunit of the essential bacterial enzyme DNA gyrase, were compared with 18 of their analogs for the inhibition of Escherichia coli DNA gyrase supertwisting activity in vitro and of bacterial multiplication. This family of compounds has a 4-hydroxy-8-methylcoumarin core substituted in the 7 and 3 positions. Important for enzyme inhibition in vitro is a 7 ether linkage to a 3'-substituted noviose sugar. The 3'-ester-linked 5-methylpyrrole, found in the coumermycin series, conferred at least 10-fold more inhibitory activity than did the similarly linked amide, found in the novobiocin series; lack of the pyrrole and amide results in the loss of inhibitory activity. Of many aryl and alkyl substituents linked as an amide at the 3 position, the 4-hydroxyl-3-(3-methyl-2-butenyl)benzoic acid moiety, found in novobiocin and clorobiocin, and the reduplication of the coumarin-noviose-5-methylpyrrole, found in coumermycin A1, were most effective in gyrase inhibition. In vivo, the ability of these compounds to inhibit the growth of E. coli varied greatly. The enhanced inhibition of gyrase in vitro conferred by a 5-methylpyrrole relative to an amide in the 3'-noviose position was reflected in inhibition of bacterial multiplication. Several substitutions at the 3 position of the coumarin core conferring similar antagonism of gyrase in vitro resulted in substantially different inhibitory activities for E. coli, suggesting that these moieties at the 3 position affect drug access to the intracellular target. This target was shown for isobutyryl PNC-NH2 (PNC-NH2 is 3-amino-4-hydroxy-8-methyl-7-[3-O-(5-methyl-2-pyrrolylcarbonyl)noviosyloxy] coumarin) and confirmed for novobiocin, coumermycin A1, and clorobiocin to be in the B subunit of DNA gyrase.
꼼바웅 왕조의 몰락: 밍군-밍곤다잉 반란과 그 영향을 중심으로 (2013)

This study reexamines a covert factor of the colonization of Myanmar kingdom, drawing on the case of Myingyun-MyingonDaing Rebellion broke out in 1866. It criticizes that existing discussions on the downfall of the Konbaung dynasty are preoccupied with post-colonialism. These researches were focus on macro level and pointed out the imperialist stratagem and many scholars concluded for the down fall of Konbaung Dynasty that the wave of Imperialism as Sunami hit from Europe to Asia so that Myanmar could not stand as feudal society and down fall Konbaung Dynasty. All of events and comments were quite true but it is necessary to examine carefully past events. There were many controversial facts about third Anglo-Myanmar war. This paper has pointed out the Kings Mindon`s false political strategic due to the lack of awareness on external threat with the giving the best example of Myingun-MyingonDaing rebellion.
A 960-Mb/s/pin interface for skew-tolerant bus using low jitter PLL (1997)

This paper describes an I/O scheme for use in a high-speed bus which eliminates setup and hold time requirements between clock and data by using an oversampling method. The I/O circuit uses a low jitter phase-locked loop (PLL) which suppresses the effect of supply noise. Measured results show peak-to-peak jitter of 150 ps and r.m.s. jitter of 15.7 ps on the clock line. Two experimental chips with 4-pin interface have been fabricated with a 0.6 /spl mu/m CMOS technology, which exhibits the bandwidth of 960 Mb/s per pin.

Throat swab and saliva specimens are inferior to NP specimens for the detection of respiratory viruses but might be acceptable for screening in a setting where it is impractical to obtain an NP specimen.
WLC34-5: GDCF: Grouping DCF for the MAC layer enhancement of 802.11 (2006)

The 802.11 has emerged as the prominent wireless LAN technology as the mobile computing devices such as notebooks and PDA have replaced the desktop computers to be the main trend products. However, if the number of active stations is large for the legacy backoff algorithm (DCF) of the 802.11, the capacity will be very low due to high collision cost. In this paper, we introduce the TDMA concept to partition all numerous active stations into several groups to avoid all stations transmitting the frames simultaneously. When Point Coordinator (PC, generally referring to AP) finds that the number of active stations (M) is large i.e. bigger than 16, it broadcasts grouping number and grouping head bits (such as 00000100 00000000) information in the TIM field of the beacon frame. Once all stations receive this instruction, the stations which last two LSB bits of the MAC address are 00 belonging to group 0 will transfer their frame first. On the contrary, all stations belonging to other groups will set their waiting time, that is, Network Allocation Vector (NAV) much more precisely. Analysis shows that the capacity of our GDCF will be near to the theoretical capacity of 802.11 WLAN even if the distributions of all active stations among all groups are not so uniform. This capacity could be independent of the number of active stations and CW <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</sub> (contention window maximum).
Induction of a reference data model for tracking and tracing (2002)

In this paper research on tracking and tracing is described. The objective of the research paper is the establishment of a general set of requirements and a general modelling solution for tracking and tracing. A reference modelling solution is obtained from different cases through the method of requirements induction. Several manufacturing situations are selected for the gathering and analyses of the requirements: a slaughter facility, a food processor and a pharmaceutical manufacturer. The paper describes the traceability requirements of these manufacturing situations in natural language and accordingly induces a general modelling solution: a reference data model. The model obtained, can represent all raw materials, parts, intermediates and subassemblies, which a process transforms into a particular end product, through the sequence of operations. Using the model, one can determine the composition of a material item out of component items and list all material items, having consumed a certain component of specific interest. The reference data model can be used in blueprinting information systems for tracking and tracing.
Evaluation of a newly developed direct agglutination test (DAT) for serodiagnosis and sero-epidemiological studies of visceral leishmaniasis: comparison with IFAT and ELISA (1987)

A newly developed direct agglutination test (DAT) for visceral leishmaniasis, IFAT and ELISA were applied to sera of patients with visceral leishmaniasis, African and American trypanosomiasis, other parasitic infections and healthy controls. The sensitivities of the 3 tests were comparable (96.3% to 100%); excluding patients with African and American trypanosomiasis, the specificities of DAT and IFAT were 100% and ELISA 87.3%. When trypanosomiasis sera were included, the specificities were 72.6%, 94.3% and 79.4% in DAT, IFAT and ELISA respectively. In 273 sera from a leishmaniasis endemic area (Baringo District, Kenya), the sensitivity was 80% in DAT and IFAT and 60% in ELISA, specificities being 99.6% (DAT), 98.5% (IFAT) and 62.5% (ELISA). As the new DAT is economical and easy to perform, it is recommended for sero-epidemiological field work on visceral leishmaniasis.

Flow Cytometric Analysis for the Evaluation of the Rat Sperm Viability and Number in the Male Reproductive Toxicity Studies (1995)

Abstract We investigated the application of flow cytometric analysis to evaluate the rat sperm viability and number in the male reproductive toxicity studies. Flow cytometric procedure has been developed to evaluate sperm number and viability that uses fluorescent dye (propidium iodide, PI) to distinguish between viable (negative staining) and dead (positive staining) sperm. Sperm samples were collected from the caudal epididymides of SD rats (13–21 weeks old). PI staining patterns/viabilities were compared among several ranges of sperm concentrations, and several kinds of sperm viability. Viabilities determined by flow cytometry (FC) were also compared with motility by direct microscopical observation in several kinds of sperm viability. No notable changes in the PI staining patterns/viabilities were observed in the range from 1 × 10 5 to 6 × 10 6 sperm/ml. Essentially similar results were obtained from both FC and microscopical analyses for three degrees of viability sperm: live sperm (general preparation as a control), weakly viable sperm (mixed by vortex mixer for 30 seconds), and dead sperm (treated with 90°C or Triton X‐100). Viabilities of normal rat samples were 95.0 ± 4.0% in FC and 93.7 ± 4.6% in microscopical observation, indicating good correlation in both analyses. Sperm numbers with FC analysis were approximately 0.8 × 10 6 to 1.8 × 10 6 sperm per mg indicating good correlation with those by microscopy. It was concluded that the present flow cytometric procedure was objective, rapid and reliable, and that it was one of the useful methods for measuring the number and evaluating the viability of sperm collected from the caudal epididymides of rats in the male reproductive toxicity studies.
PREPARATION AND SWELLING PROPERTIES OF SUPER-ABSORBENT POLYMER (1996)

A super-absorbent polymer is prepared by graft polymerizing acrylamide (AM) onto potato starch using eerie ammonium nitrate (CAN) and N, N&#39;-methylene-bis-acrylamide (bisAM) as an initiator and cross-linking agent respectively, and then subjecting the potato starch- poly(acrylamide) (PAM) graft copolymer (SPAM) to alkaline saponification. The water absorbency (WA) of the sample is nearly 5000 g H2O/g for dry sample in 24 h at room temperature and is far larger than that of reported in the literature([1]). The variables affecting the WA were investigated and optimiz;ed, they were: concentrations of potato starch, AM, CAN and bisAM were 26.3 g/L, 1.14 mol/L, 10.3 mmol/L and 0.53 mmol/L, respectively. The amount of sodium hydroxide was 15 g and the temperatures of graft copolymerization and saponification reactions were 60 degrees C and 95 degrees C. The time of graft copolymerization and saponification reactions was 2 h, respectively.
The Release of Outer Membrane Vesicles from the Strains of Enterotoxigenic <i>Escherichia coli</i> (1995)

The clinically isolated heat labile enterotoxin (LT)-producing strains of Escherichia coli can be separated into two groups, namely spontaneous LT-releasing strain and non-spontaneous LT-releasing strain, based on their phenotypes of spontaneous release of LT into the culture medium. The phenotype of spontaneous LT release was observed to correlate closely with the phenotype of the release of numerous small vesicles into the culture medium. Both morphological and biological examinations of the vesicle showed that the vesicle was released from the outer membrane. It can, therefore, be assumed that LT may be released from the cell at the time the vesicles form.
