Dental health education by “barefoot doctors” (1983)

In an insurance company 18 out of 507 employees were trained as dental health educators. They then informed their fellow workers about prevention of caries and periodontal disease in groups of about 10 persons. Two information meetings were held during a period of 10 months. Eighty-nine percent of the employees were positive to this educational programme. Twenty-two percent said that they had reduced the intake of sucrose after the first meeting. Even more persons reduced their sucrose intake later. Saliva secretion rate and buffer capacity were analyzed and the number of lactobacilli and Streptococcus mutans were determined before and after the information meetings. A significant reduction in the number of lactobacilli was found, confirming the change in carbohydrate intake. The information raised the level of knowledge about dental health among the employees. It was suggested that this type of educational programme should be used in other health areas.
Simultaneous bi-plane digital video-fluoroscopy. (1982)

A prototype system for digital subtraction angiography that is capable of acquiring digitized video-fluoroscopic images simultaneously from both anterior and lateral imaging chains of a conventional bi-plane system was developed. A hardware module that takes images from both the anterior and lateral video cameras and displays them both on a single video image prior to digitization was designed and constructed. The three-dimensional information provided by a digital bi-plane images should improve the accuracy of cardiac-ventricular function studies. In addition, bi-plane imaging should reduce the need for additional views and the associated repeated injections of contrast media. With this technique, digital bi-plane imaging can be carried out with commercially available systems without duplication of the digital-processing chain.
Simultaneous speech segmentation and phoneme recognition using dynamic programming (2002)

In this paper a dynamic programming algorithm for simultaneous speech segmentation and phoneme recognition is presented. Given a sequence of samples of an unknown speech pattern and a library of phonemes, this algorithm finds the best phonological match and, with a backtracking step, identifies the phoneme boundaries. This approach is different from a traditional two step process whereby first the phoneme boundaries are determined locally and then speech recognition is performed. Its advantage over the two step process is that incorrect phoneme boundaries due to slurring or sudden changes in the speech are reduced. Unlike other dynamic programming algorithms, it does not lend itself to systolic wavefront processing, hence an alternate parallel algorithm is presented.
Corrosion Control in the Oil and Gas Production – 5 Successful Case Histories (2007)

Abstract Corrosion remains a key issue in petroleum production. Its continued occurrence has consequences on the safety of people and environment and the integrity of facilities and affects the economy of the oil or gas field. Particularly the presence of severe environments containing corrosive components such as carbon dioxide and hydrogen sulphide poses serious problems. A central element in the design of facilities and the corrosion control is therefore the proper choice of materials which are both, economical and provide a satisfactory performance over the entire service life with respect to the given environment. Prior to the production phase, reliable corrosion monitoring programmes have to be selected, established, and implemented, as necessary. This paper gives a comprehensive overview of the long time experience of the authors’ company regarding these considerations: one large oil field developed about 50 years ago in Austria and 4 gas fields, two of them in Austria and two in Pakistan are described. The different gas fields have been successfully developed and brought on stream between 1967 and 2003. These gas fields do not only vary in their geographical position, but also in gas compositions, the dates of production start, and the location of gas dehydration units. One major aspect dealt with in each of these cases is the material selection with respect to the given environment, the implementation in the field and the corrosion monitoring. Where the initial decision has been made in favour of carbon steel, the inhibitor selection in the laboratory and the inhibitor application and optimization in the field are described. Furthermore, for the oil field a lot of technical measures are described, some of them having derived from R&D projects. These measures have led to a tremendous decrease in workovers and linepipe failures und thus to huge cost reductions. The corrosion monitoring results which are presented in this paper give evidence of the experience gained in more than five decades of the production and transportation of oil and more than three decades of the production and transportation of wet corrosive natural gas.
NUMERICAL EXPERIMENTS OF MULTI REFRACTION OF ATMOSPHERIC WAVES ON PERFECT BASIC FLOWS (1999)

By using a global spectral model of quasi geostrophic barotropic vorticity equation including diabatic heating,a series of numerical experiments of multi refraction of atmospheric waves on perfect basic flows are run.The 16 perfect basic flows and 4 heat sources of tropical SSTA are considered and 30 days are taken for model integration. Results show that: (1) Disturbance excited by the heat source usually can have two or three branches of the wave trains, and the second or the third branch of the wave trains bifurcate from the first branch, or the third branch wave train bifurcates from the second. (2) For some basic flows, the first branch wave train disappears after maintaining two weeks or longer, and the other wave trains propagate still. (3) The second branch of wave train is the strongest in most cases and two branches of wave trains have the tendency of confluencing and focusing.
INVERSE RELATIONSHIP BETWEEN PIGMENT EPITHELIUM DERIVED FACTOR (PEDF) AND VASCULAR ENDOTHELIAL GROWTH FACTOR (VEGF) IN HUMAN PANCREATIC CANCER (2007)

Introduction: The development of pancreatic cancer is regulated by a balance between proangiogenic and antiangiogenic factors. Pancreatic cancer is the fourth leading cause of cancer related deaths in the United States. Pigment epithelium derived factor (PEDF) is an anti-angiogenic protein that has been shown to inhibit pancreatic cancer cell growth. Furthermore, low expression of PEDF has been linked to increased hepatic metastasis and decreased overall survival. Vascular endothelial growth factor (VEGF) is an angiogenic factor that has been found to be over-expressed in pancreatic cancer. Our aim was to evaluate the relationship between PEDF and VEGF levels in pancreatic cancer. Methods: Enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC) were used to measure the expression levels of these two proteins in human serum and tissue respectively. Tumors from 140 pancreatic cancer patients were evaluated for PEDF and VEGF. PEDF and VEGF levels were measured in human serum from patients with malignant tumors (n = 38) and non-malignant tumors (n = 21). Results: On IHC, 28% of tumors had PEDF expression whereas 80% of tumors showed elevated VEGF expression. Tumors overexpressing VEGF (2+ or 3+ staining) had decreased expression of PEDF (p < 0.05). On serum analysis, 18% of cancer patients had measurable quantities of PEDF whereas 100% of cancer patients had VEGF expression. The mean PEDF serum level was 180.9 pg/mL (±495 pg/mL) for and the mean VEGF level was 440.5 pg/mL (±357 pg/mL). Conclusion: Our data demonstrates an indirect relationship between PEDF and VEGF in pancreatic cancer. This supports the importance of the loss of the anti-angiogenic factor, PEDF, in the progression of human pancreatic cancer.

Alkylation of Isobutane with C<sub>3</sub>−C<sub>5</sub> Olefins To Produce High-Quality Gasolines:  Physicochemical Sequence of Events (2003)

Alkylation of isobutane with C3−C5 olefins currently produces alkylates that are the highest-quality and cleanest-burning gasolines. Four processes are widely used; two employ sulfuric acid as the catalyst, whereas the other two employ liquid HF. Processes that employ solid catalysts have yet to be commercialized. This paper comprises a review of recent findings concerning the fundamentals (chemistry of alkylation plus side reactions, mass- and heat-transfer steps in the acid/hydrocarbon dispersions, characteristics of dispersion, etc.), i.e., the physicochemical events. A sequence of over 30 chemical, physical, and transfer steps is outlined and explained, for probably the first time. Better understanding of the fundamentals strongly suggests that much improved processes can be developed.

Mutants of Bacillus subtilis Defective in Protein Export (1988)

We have isolated a set of strains with mutations (designated prs) that decrease secretion of alpha-amylase and have a pleiotropic effect on secretion of other exoproteins. The seven mutants were selected in a strain of Bacillus subtilis which overproduces alpha-amylase due to the presence of an alpha-amylase gene on a multicopy plasmid. The mutations were mapped to four different chromosomal loci. The phenotype of the mutants, especially their pleiotropic effects and the accumulation of alpha-amylase precursor, indicated that they have defects in the mechanism of protein export. Double mutants with certain pairwise combinations of mutations in different loci had additive effects on secretion, suggesting that these prs genes encode different components of the secretion pathway.

Transcutaneous immunization induces mucosal CTLs and protective immunity by migration of primed skin dendritic cells (2004)

Transcutaneous immunization (TCI), the application of vaccines on the skin, induces robust systemic and mucosal antibodies in animal models and in humans. The means by which mucosal immune responses to vaccine antigens are elicited by TCI has not been well characterized. We examined the effect of TCI with an HIV peptide vaccine on the induction of mucosal and systemic CTL responses and protective immunity against mucosal challenge with live virus in mice. Robust HIV-specific CTL responses in the spleen and in the gut mucosa were detected after TCI. The responses were dependent upon the addition of an adjuvant and resulted in protection against mucosal challenge with recombinant vaccinia virus encoding HIV gp160. Although it is clear that adjuvant-activated DCs migrated mainly to draining lymph nodes, coculture with specific T cells and flow cytometry studies with DCs isolated from Peyer's patches after TCI suggested that activated DCs carrying skin-derived antigen also migrated from the skin to immune-inductive sites in gut mucosa and presented antigen directly to resident lymphocytes. These results and previous clinical trial results support the observation that TCI is a safe and effective strategy for inducing strong mucosal antibody and CTL responses.

FATAL HERPESVIRUS HEMORRHAGIC DISEASE IN WILD AND ORPHAN ASIAN ELEPHANTS IN SOUTHERN INDIA (2013)

Up to 65% of deaths of young Asian elephants (Elephas maximus) between 3 mo and 15 yr of age in Europe and North America over the past 20 yr have been attributed to hemorrhagic disease associated with a novel DNA virus called elephant endotheliotropic herpesvirus (EEHV). To evaluate the potential role of EEHV in suspected cases of a similar lethal acute hemorrhagic disease occurring in southern India, we studied pathologic tissue samples collected from field necropsies. Nine cases among both orphaned camp and wild Asian elephants were identified by diagnostic PCR. These were subjected to detailed gene subtype DNA sequencing at multiple PCR loci, which revealed seven distinct strains of EEHV1A and one of EEHV1B. Two orphan calves that died within 3 days of one another at the same training camp had identical EEHV1A DNA sequences, indicating a common epidemiologic source. However, the high level of EEHV1 subtype genetic diversity found among the other Indian strains matches that among over 30 EEHV1 strains that have been evaluated from Europe and North America. These results argue against the previous suggestions that this is just a disease of captive elephants and that the EEHV1 virus has crossed recently from African elephant (Loxodonta africana) hosts to Asian elephants. Instead, both the virus and the disease are evidently widespread in Asia and, despite the disease severity, Asian elephants appear to be the ancient endogenous hosts of both EEHV1A and EEHV1B.
DNA Damage Induced Inhibition of RNA Polymerase II and the Contributions of BRCA1 (2008)

Cellular DNA damage elicits the phosphorylation and ubiquitination of RNA polymerase (RNAPII), leading to the global repression of transcription. Here we show that there are at least two different pathways to transcriptional repression, depending on the type of DNA damage. After H2O2 treatment, transcription was rapidly inhibited and rapidly restored. On the other hand, UV treatment caused a much slower transcriptional inhibition, with a corresponding depletion of unphosphorylated RNAPII. We found that after UV treatment, but not treatment with H2O2, the inhibition of transcription was dependent on both the proteasome and new protein synthesis. In addition, RNAPII activity and ubiquitination were regulated through the phosphorylation of RNAPII by the P‐TEFb kinase. Furthermore, we show that BRCA1 is associated with the ubiquitination of RNAPII in response to UV induced DNA damage. These results highlight that multiple cellular pathways exist to globally repress transcriptional processes that might interfere with the repair of DNA damage.

Cyclooxygenase-1 Inhibition Shortens the Duration of Diazepam-Induced Loss of Righting Reflex in Mice (2005)

Cyclooxygenase-1 (COX-1) inhibition by a selective inhibitor valeryl salicylate, or nonselective inhibitors at 10 mg/kg, including aspirin, ibuprofen, indomethacin, and picroxicam, attenuated by 29%-46% the duration of loss of righting reflex induced by diazepam (20 mg/kg) in mice. On the other hand, arachidonic acid (20 mg/kg) increased the duration of diazepam-induced loss of righting reflex by 48%. This effect of arachidonic acid was abolished by aspirin. However, aspirin at 10 mg/kg also did not alter the effects of diazepam (5 mg/kg) on spontaneous activity and rotarod performance. These findings strongly suggest that one or more COX products, most likely prostaglandins, play a significant role in modulating the hypnotic effect of diazepam. Elucidating the mechanism involved may further our understanding of the pharmacology of benzodiazepines.
Generalized linear sampling method for the inverse elastic scattering of fractures in finite bodies (2019)

Abstract In this work, we consider a mathematical foundation for elastic-wave reconstruction of multiply-connected fractures in a finite solid body by way of the Generalized Linear Sampling Method. To allow for the presence of partially-closed fractures as is often the case in non-destructive testing applications, we describe the contact behavior of ‘hidden’ fractures by the Schoenberg’s linear slip model. We further assume that the elastic body (probed for fractures) is supported by either by Robin or Dirichlet boundary conditions, while the rest of its boundary is taken to be of Neumann type and used for both fracture illumination and gathering of sensory data. To cater for the application of GLSM to laboratory ultrasonic sensing of fractures in slab-like rock specimens, we assume the finite elastic body to be a subset of ; however the results of this study are mostly dimension-generic and allow for a straightforward extension to inverse elastic scattering in finite subsets of .
