Effects of pH and Alum Concentrations on TiO2 Capture on Cellulose Fibers during Co-Filtration (2004)

Much research has been carried out to correlate the surface charges to particle capture in papermaking and filtration industries. Most of the previous works model the co-filtration process of simultaneous fibrous mat formation and filler particle capture as a sequential combination of cake and depth filtration. Very few works have quantified the surface charge and related it to the filtration behavior. The objective of this work is to model the co-filtration process through multiphase transport theory, coupled with the postulated constitutive equations and explain the dominant particle capture mechanism under different water chemistry conditions.
The model proposed here is compared with experimental data from a co-filtration process of raw paper formation using cellulose fibers, Tio2particles as the fillers, and alum as the salt additive. The zeta potentials, i. e , effective surface charges, of cellulose fibers and TiO2 particles under different conditions were measured prior to filtration experiments. The pH, salt and particle concentrations were varied in bench and pilot filtration experiments. The results of filtration experiments show a significant effect of material surface charges on particle capture efficiency. The filtration efficiency increased between 30%to over 50%by adding the salt to the slurries.
The model equations with constitutive functions were numerically solved and the capture coefficients were optimized using a genetic algorithm to best fit the experimental data. AFPRTRAM program was written to handle the moving boundary condition (function of time) of co-filtration process. A dimensionless zeta potential function was defined to relate the zeta potentials of both the fibers and the filler particles and incorporated into the particle capture relation. The capture relation separates the particle capture due to electrostatic attraction from other capture mechanisms. The model results show electrostatic attraction between fibers and fillers to be the dominant particle capture mechanism when salt is added to the slurry.
Cryosurgery for common skin lesions. Treatment in family physicians' offices. (1999)

Evidence from case report and series suggests that cryosurgery is effective for actinic keratoses, seborrheic keratoses, dermatofibroma, keloids, molluscum contagiosum, and benign nevi. Randomized comparative trials show that, for external genital warts, cryosurgery is more effective than podophyllin treatment, better than or equal to trichloroacetic acid, but less effective than electrodesiccation or surgical removal. Prospective randomized trials of cryosurgery for common warts showed that weekly cryotherapy produced more rapid cures, but the overall cure rate depended on number of treatments. Two freeze-thaw cycles and paring before freezing improved the cure rate for plantar warts.
Protein and RNA Quantification of Multiple Genes in Single Cells (2018)

Single-cell analysis overcomes the problems of cellular heterogeneity by revealing the individual differences between cells in tissue. The current tools used to profile gene expression at the single-cell level are arduous and often require specialized equipment. We have previously developed a technique to quantify protein expression levels in single living cells. Here, we combine quantification of protein expression with absolute measurement of mRNA amounts of the same gene in the same cell, to profile the expression of genes at the transcriptional and translational levels. We show that high heterogeneity exists at both the mRNA and protein levels for multiple genes, even among monoclonal cells. We demonstrate a rapid, straightforward approach to single-cell profiling of RNA and protein production.
Detail-Enhanced Multi-Scale Exposure Fusion (2017)

Multi-scale exposure fusion is an effective image enhancement technique for a high dynamic range (HDR) scene. In this paper, a new multi-scale exposure fusion algorithm is proposed to merge differently exposed low dynamic range (LDR) images by using the weighted guided image filter to smooth the Gaussian pyramids of weight maps for all the LDR images. Details in the brightest and darkest regions of the HDR scene are preserved better by the proposed algorithm without relative brightness change in the fused image. In addition, a new weighted structure tensor is introduced to the differently exposed images and it is adopted to design a detail extraction component for the proposed fusion algorithm, such that users are allowed to manipulate fine details in the enhanced image according to their preference. The proposed multi-scale exposure fusion algorithm is also applied to design a simple single image brightening algorithm for both low-light imaging and back-light imaging.
Activity of Neutrophil β-Glucuronidase in Diabetic and Nondiabetic Patients With Chronic Generalized Periodontitis and Healthy Subjects (2011)

OBJECTIVE. The aim of the study was to establish the dynamics of β-glucuronidase activity in subjects suffering from type 1 diabetes and chronic untreated generalized periodontitis, subjects suffering from chronic untreated generalized periodontitis only, and control subjects not suffering from generic diseases with healthy periodontal tissue. MATERIAL AND METHODS. The study involved 165 19-50-year-old subjects who were divided into three groups: healthy subjects (n=55), subjects with chronic untreated generalized periodontitis (n=55), and subjects with type 1 diabetes and chronic untreated generalized periodontitis (n=55). Neutrophilic leukocytes of peripheral venous blood were exposed to bacterial stimuli: opsonized zymosan, nonopsonized Staphylococcus aureus, and prodigiosan. The activity of β-glucuronidase was determined by the spectrofluorimetry method. RESULTS. The diagnostic value of changes in β-glucuronidase activity of neutrophilic leukocytes markedly increased in all study groups after stimulation of neutrophilic leukocytes by opsonized zymosan, nonopsonized Staphylococcus aureus, and prodigiosan as compared to control media not exposed to any stimulus (P<0.001). The strongest relationship (canonical correlation coefficient eta, 0.993) between the intensity of periodontal pathology markers and the activity of β-glucuronidase of neutrophilic leukocytes in incubated media in patients with type 1 diabetes mellitus and periodontitis was found under the effect of nonopsonized Staphylococcus aureus. CONCLUSIONS. If periodontal impairment is severe, diabetes mellitus possibly causes a faster destruction of the periodontal tissue and presents a higher risk of periodontitis for patients with diabetes.

A new faculty orientation program: Building a core of new faculty to shape the future of the college (2002)

Abstract St. Louis Community College leadership recognized that a new large cohort of faculty hired to replace retiring instructors would shape the college over the next quarter century and beyond. The college challenged its staff development team to create a program that would integrate new faculty into the college and prepare them for the vital role they would play.
Continuous Reduction of Iron Ore with Coal in an Electrically Heated Furnace (1986)

AbstractAbstractThis paper presents the results of a fundamental study for the development of a new ironmaking process based on coal and iron ore concentrates [1]. The coal/iron ore mixture is fed mechanically and continuously through a reaction tube in a tubular, electrically heated furnace. Investigations have been made on the effect of several of the most important operating variables, i.e. temperature, linear velocity of solids, coal particle size and coal/iron ore ratio, on the degree of metallization and on the smoothness of the operation. The gases generated during reactions have also been analysed. The rapid rate of metallization obtained and the composition of gases generated indicate that development of a new and economical ironmaking process is encouraging.
Trans-Splicing and Alternative-Tandem-Cis-Splicing: Two Ways by Which Mammalian Cells Generate a Truncated SV40 T-Antigen (1996)

The early SV40 BstXI-BamHI (Bst/Bam) DNA fragment encodes exclusively for the second exon of the large T-antigen and contains the intact small t-antigen intron. Rat cells transformed by the p14T, a construct that carries the Bst/Bam DNA fragment as a tail-to-head tandem duplication, synthesize a truncated T-antigen (T1-antigen) without having a direct equivalent at the DNA level. Formation of the T1-mRNA occurs by means of two distinct mechanisms: alternative-tandem-cis-splicing and trans-splicing. To generate the T1-mRNA the cells utilize a cryptic 5' splice site, located within the second exon of the large T-antigen and the regular small t-antigen 3' splice site. Since these splice sites are in an inverted order two Bst/Bam transcripts are required to generate one T1-mRNA molecule. For alternative-tandem-cis-splicing the cells utilize a 4.4 kb pre-mRNA that contains the sequence of the entire Bst/Bam tandem repeat. The proximal Bst/Bam segment provides the 5' donor splice site and the distal segment the 3' acceptor site. This requires that the pre-mRNA not be cleaved after the RNA polymerase II has passed the polyadenylation signal of the proximal Bst/Bam DNA segment. Synthesis of the 4.4 kb pre-mRNA was demonstrable by RT-PCR but not by Northern blot analysis. For trans-splicing, the cells utilize two separate pre-mRNA molecules. One transcript provides the cryptic 5' splice donor site and the other the 3' splice acceptor site. To demonstrate this a three base pair deletion was introduced into the proximal Bst/Bam segment of the p14T DNA (p14Tdelta-3) as a marker, destroying the recognition site for Pf/MI restriction enzyme. This deletion allowed the differentiation between the proximal and distal Bst/Bam segment. RT-PCR analysis and DNA sequencing confirmed that the p14Tdelta-3 transformed cells generate the T1-mRNA by intra- and inter-molecular RNA splicing.
Evaluation of a Cr3C2(NiCr) Coating Deposited on s4400 by Means of an HVOF Process and Used for Flow Plates of PEM Fuel (2012)

In this research the electrochemical behavior of a Cr3C2(NiCr) coating deposited on S4400 through the use of an HVOF (high velocity oxygen-fuel) thermal spraying process was studied. The electrolyte used was a solution of H2SO4 0.5 M + 2 ppm Fˉ used at environment temperature. As a reference electrode a mercurous sulfate (Hg2SO4) was used and a graphite bar as a counter electrode. The morphological aspect of the coating evaluated was analyzed by SEM (Scanning Electron Microscopy) before and after the electrochemical evaluation. The coating electrochemical values obtained for a period of 576 hrs fulfilled the corrosion resistance criteria required by USDOE (US Department of Energy). As a starting point, this coating could be considered in flow plates for PEM-based (Proton Exchange Membrane) fuel cells. Nevertheless, the loss of coating during this period may limit its application.
Oral Trypsin-inhibitor-induced Improvement of the Exocrine and Endocrine Pancreatic Functions in Alloxan Diabetic Rats (1976)

Studies are presented dealing with the effect on the exocrine and endocrine pancreas of long-term oral trypsin inhibitor administration to alloxan diabetic rats. Three categories of rats were used: a) normal rats, b) alloxan diabetic rats, and c) alloxan diabetic rats treated with the trypsin inhibitor. 1. The concentration of amylase in both pancreas and intestinal contents were markedly decreased in alloxan diabetic rats as compared with normal rats, whereas the concentrations of lipase and trypsin(ogen) were practically unaffected by the diabetic state. 2. Trypsin inhibitor treatment of diabetic rats enhanced the concentrations of both amylase, trypsin(ogen), and lipase in pancreas and intestinal contents when compared with untreated diabetic controls. 3. Alloxan diabetic rats treated with trypsin inhibitor displayed an increased weight gain, increased pancreatic weight, and increased pancreatic protein concentration as compared with the untreated diabetic controls. 4. Alloxan diabetic rats treated for 3 or 5 weeks with the trypsin inhibitor were found to have decreased basal blood glucose levels and an increased plasma insulin: blood glucose ratio as compared to the untreated diabetic controls. 5. There was no apparent difference in the glucose elimination rate after I.V. glucose loads in diabetic rats given trypsin inhibitor and their diabetic controls. However, the insulin secretory response to the glucose stimulus was slightly improved in the trypsin inhibitor group. 6. Alloxan diabetic rats treated with trypsin inhibitor had an increased total pancreatic insulin content compared with their diabetic controls. It is concluded that long-term daily treatment with oral trypsin inhibitor in alloxan diabetic rats increased enzyme production and secretion in the exocrine pancreas, and produced an improvement of the diabetic condition of the animals. This improvement might partly be due to an increased pancreatic content and secretion of insulin.
Yield Ramp up by Scan Chain Diagnosis (2009)

Advances in the semiconductor manufacturing technologies have resulted in the defect distribution to both random defects and process weakness due to smaller geometry. The keep-increasing complexity of the designs makes the traditional failure analysis and yield learning techniques inadequate for finding the root cause.

Application of poly(ethylene naphthalate) films to electrical and audio-visual uses in Japan (1996)

The introduction and development of biaxially-oriented poly(ethylene naphthalate) film (PEN film) in Japan has been compared with the biaxially-oriented poly(ethylene terephthalate) film (the PET film), which is usually mass-produced for electrical and audio-visual uses. Its physical, mechanical, electrical, thermal, chemical, optical and surface properties and radiation resistance were reviewed and its superiority over the PET film, such as a higher Young's modulus, a higher Tc, higher long-term heat-resistance, a smaller thermal shrinkage coefficient, smaller oligomer extraction, better hydrolysis resistance, better radiation resistance and a lower surface friction coefficient were illustrated. Taking advantage of these excellent properties, its practical applications to electrical and electronic, audio-visual and miscellaneous uses in Japan were exemplified and a new direction for its future development and application has been suggested.
Object Identification and Retrieval from Efficient Image Matching. Snap2Tell with STOIC dataset (2005)

Abstract. Traditional content based image retrieval attempts to retrieve images using syntactic features for a query image. Annotated image banks and Google allow the use of text to retrieve images. In this paper, we studied the task of using the content of an image to retrieve information in general. We describe the significance of object identification in an information retrieval paradigm that uses image set as intermediate means in indexing and matching. We also describe a unique Singapore Tourist Object Identification Collection with associated queries and relevance judgments for evaluating the new task and the need for efficient image matching using simple image features. We present comprehensive experimental evaluation on the effects of feature dimensions, context, spatial weightings, coverage of image indexes, and query devices on task performance. Lastly we describe the current system developed to support mobile image-based tourist information retrieval. 1
3-(ETHOXYCARBONYL)-2-METHYLPYRROLE-5-CARBOXALDEHYDE AS A VERSATILE SYNTHONE FOR POTENTIAL ANTIBACTERIAL AGENTS (1995)

Reaction of 3-(ethoxycarbonyl)-2-methylpyrrole-5-carboxaldehyde with substituted thiosemicarbazides afforded the corresponding (thiocarbamoyl) hydrazones. The latter compounds underwent cyclization to thiazole, thiazolidinone, thiazinone and thiadizole derivatives under the proper reaction condition. All the prepared compounds were evaluated for this antimicrobial activity.
Contrast-enhanced ultrasound: clinical applications in patients with atherosclerosis (2015)

Contrast-enhanced ultrasound (CEUS) is increasingly being used to evaluate patients with known or suspected atherosclerosis. The administration of a microbubble contrast agent in conjunction with ultrasound results in an improved image quality and provides information that cannot be assessed with standard B-mode ultrasound. CEUS is a high-resolution, noninvasive imaging modality, which is safe and may benefit patients with coronary, carotid, or aortic atherosclerosis. CEUS allows a reliable assessment of endocardial borders, left ventricular function, intracardiac thrombus and myocardial perfusion. CEUS results in an improved detection of carotid atherosclerosis, and allows assessment of high-risk plaque characteristics including intraplaque vascularization, and ulceration. CEUS provides real-time bedside information in patients with a suspected or known abdominal aortic aneurysm or aortic dissection. The absence of ionizing radiation and safety of the contrast agent allow repetitive imaging which is particularly useful in the follow-up of patients after endovascular aneurysm repair. New developments in CEUS-based molecular imaging will improve the understanding of the pathophysiology of atherosclerosis and may in the future allow to image and directly treat cardiovascular diseases (theragnostic CEUS). Familiarity with the strengths and limitations of CEUS may have a major impact on the management of patients with atherosclerosis.
Alcohol, Amines, and Alkaloids: A Possible Biochemical Basis for Alcohol Addiction (1970)

Tetrahydropapaveroline is a benzyltetrahydroisoquinoline alkaloidderivative of the biogenic amine, dopnmine. Alcohol, by way of its primary metabolite, acetaldehyde, competitively inhibits nicotinamide-adenine Sinucleotide-linked aldehyde dehydrogenase and augments the formation of tetrahydropapaveroline in vitro. The limited capacity of brain to oxidize aldehydes may be of pharmacological importance because it facilitates the production of tetrahydropapaveroline in the presence of drugs which inhibit this enzyme.
Efficacy of skin barrier creams (IV). The repetitive irritation test (RIT) with a set of 4 standard irritants (1994)

An improved human model for the quantification of skin barrier creams (BCs) is described. In contrast to the previously published procedure, the back, instead of the forearm, and a total of 4 irritants are used. Due to the larger area, 3 BC formulations can be simultaneously compared to the control field, which receives the irritant only, without BC-pretreatment. On 10 human volunteers, the irritants 10% sodium lauryl sulfate (SLS), 1% sodium hydroxide (NaOH), 30% lactic acid (LA) and undiluted toluene (TOL) were applied via large Finn Chambers for 30 min, 5 x during the 1st week and 4 x during the 2nd week. Taktosan Salbe (water-in-oil emulsion) and RAWI Speerschutzcreme (oil-in-water emulsion) were applied 30 min before contact with the irritants. In order to assess reproducibility and interindividual variation, the BC RAWI was tested in duplicate. Irritant cutaneous reactions were quantified by 4 parameters: erythema score, transepidermal water loss, blood flow volume and stratum corneum hydration by measuring capacitance. The results showed marked differences in efficacy. Taktosan significantly suppressed irritation by SLS, NaOH and LA, which was apparent in nearly all parameters. RAWI caused significant inhibition of SLS irritation, and a positive trend against NaOH and LA was observed. Both BCs failed against TOL. The results of duplicate testing with RAWI showed good reproducibility. The dogma that oil-in-water emulsions are primarily effective against lipophilic irritants, and water-in-oil emulsions against hydrophilic irritants, needs to be re-evaluated on the basis of our findings. This model seems to have potential for further studies on BCs and might elucidate the complex interaction of BCs with irritants.
Association Between Smoking and Blood Pressure (2001)

Cigarette smoking causes acute blood pressure (BP) elevation, although some studies have found similar or lower BPs in smokers compared with nonsmokers. Cross-sectional data from 3 years (1994 to 1996) of the annual Health Survey for England were used to investigate any difference in BP between smokers and nonsmokers in a nationally representative sample of adults (>/=16 years old). Randomly selected adults (33 860; 47% men) with valid body mass index (BMI) and BP measurements provided data on smoking status (never, past, or current) and were stratified into younger (16 to 44 years old) and older (>/=45 years old) age groups. Analyses provided between 89% and 94% power to detect a difference of 2 mm Hg systolic BP between smokers and nonsmokers in the 4 age/gender strata (alpha=0.05). Older male smokers had higher systolic BP adjusted for age, BMI, social class, and alcohol intake than did nonsmoking men. No such differences were seen among younger men or for diastolic blood pressure in either age group. Among women, light smokers (1 to 9 cigarettes/d) tended to have lower BPs than heavier smokers and never smokers, significantly so for diastolic BP. Among men, a significant interaction between BMI and the BP-smoking association was observed. In women, BP differences between nonsmokers and light smokers were most marked in those who did not drink alcohol. These data show that any independent chronic effect of smoking on BP is small. Differences between men and women in this association are likely to be due to complex interrelations among smoking, alcohol intake, and BMI.
