Demand for engineering graduates is steadily growing around the world. Attracting more students into engineering has become a task of an emerging importance. Mobile robotics is an excellent tool to fascinate young boys and girls while drawing their interests to such fields as mechanical, electrical, electronic, control and computer engineering. It also allows keeping and further developing this interest during the years of study. This paper presents low- to medium-complexity autonomous mobile robots that could be directly employed at school and university levels to introduce to engineering or be used as platforms for further development by the students.
IMAGE Mission Science (1998)

Simultaneous, global measurement of major magnetospheric plasma systems will be performed for the first time with the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) Mission. The ring current, plasmasphere, and auroral systems will be imaged using energetic neutral and ultraviolet cameras. Quantitative remote measurement of the magnetosheath, plasmaspheric, and magnetospheric densities will be obtained through radio sounding by the Radio Plasma Imager. The IMAGE Mission will open a new era in global magnetospheric physics, while bringing with it new challenges in data analysis. An overview of the IMAGE Theory and Modeling team efforts will be presented, including the state of development of Internet tools that will be available to the science community for access and analysis of IMAGE observations.
Hyperasparaginemia in a schizophrenic patient. (1983)

A man with a chronic schizophrenia-like psychotic disorder had fasting plasma asparagine concentrations that were consistently 4 to 8 SD above the normal level. Asparagine levels were also high in his cerebrospinal fluid (CSF) and erythrocytes. Ornithine, proline, and glutamate concentrations were irregularly high in fasting plasma, and gamma-aminobutyric acid (GABA) concentrations were elevated in CSF. Whether or not these biochemical abnormalities were related to the psychotic disorder is unclear. However, increased asparagine concentrations, possibly due to an enzymatic deficiency of asparaginase, could lead to deregulation of polyamine biosynthesis and to excessive production of GABA from putrescine. These biochemical changes could in turn cause disordered brain function. A search in mentally ill patients for metabolic abnormalities involving asparagine, or other amino acids, might hasten elucidation of the biochemical basis of the schizophrenias.
Nucleotide sequence of a novel arylesterase gene from <i>Vibro mimicus</i> and characterization of the enzyme expressed in <i>Escherichia coli</i> (1994)

A gene coding for an arylesterase of Vibrio mimicus was cloned. Sequence determination reveals that the esterase gene has an open reading frame of 600 nucleotides which encodes a protein of M(r) 22,300. The deduced amino acid sequence contain a pentapeptide GDSLS (residues 27-31), which was also found in the phospholipid-cholesterol acyltransferase from Aeromonas hydrophila. Substitution of Ser-29 by alanine or cysteine in the cloned gene abolished the esterase activity in the tributyrin plate assay. On the other hand, the activity was not lost when Ser-31 was changed to alanine. The cloned gene was expressed in Escherichia coli, and the protein purified by a four-step procedure. The purified protein migrated on SDS/PAGE as a single band with an apparent M(r) of 22,100. This enzyme favoured the hydrolysis of several arylesters and was classified as an arylesterase (EC 3.1.1.2). N-Terminal analysis showed that Ser-20 was the first amino acid of the mature secreted protein, suggesting that the N-terminal 19 hydrophobic amino acids served as a signal peptide.
Stereoselective access to heteroarylmethylene-substituted pyrrolidines: fully organocatalytic Mannich–hydroamination reactions (2013)

A one-pot sequence of organocatalytic transformations delivers heteroarylmethylene-substituted pyrrolidines with high stereo- and enantioselectivity. A Mannich coupling of N-heteroarylalkyne aldehydes with aldimine and an original metal-free hydroamination of the resulting adducts are the key transformations of the process delivering highly functionalized molecules with high potential for synthetic applications.
El uso del cuadro de mando integral y del presupuesto en la gestión estratégica de los hospitales públicos (2010)

Examinar la relación entre el perfil de los directivos y el uso del cuadro de mando integral y del presupuesto en la consecución de objetivos estratégicos centrados en la reducción del coste y en la mejora de la flexibilidad en la prestación de servicios sanitarios. Los datos se recogieron mediante una encuesta enviada a 884 directivos miembros de equipos de dirección de 218 hospitales públicos en España. El índice de respuesta fue del 53,51%, con 473 cuestionarios útiles. Se realizó una validación métrica de las escalas usadas y un análisis del modelo con técnicas de ecuaciones estructurales. Los directores más jóvenes y con menos antigüedad suelen hacer un mayor uso del cuadro de mando integral que del presupuesto. La diversidad en el equipo de dirección está relacionada con el empleo de diferentes técnicas de control de gestión. El uso del cuadro de mando integral se relaciona positivamente con la implantación de estrategias sanitarias centradas tanto en la mejora de la flexibilidad como en el control y la reducción del coste sanitario. La adopción de sistemas de control de gestión no sólo es resultado de un proceso racional y de presiones institucionales, sino que también depende de las características de los individuos responsables de la toma de decisiones. El uso del cuadro de mando integral facilitará que los hospitales puedan implantar planes estratégicos con múltiples objetivos. To analyze the relationship between hospital managers' characteristics and the use of the balanced scorecard and the budget. A further aim was to analyze how these two techniques influence strategic goals aimed at cost reduction and enhancing service flexibility. Data were collected through a questionnaire sent to 884 members of top management teams in 218 public hospitals in Spain. The response rate was 53.51% with 473 useful questionnaires. Structural equation techniques were used to validate the metric scales and the model used. Younger managers and less tenured managers were more likely to use the balanced scorecard than the budget. Diversity in the top management team was related to the use of distinct management control techniques. The use of the balanced scorecard was positively associated with the implementation of healthcare strategies focused on enhancing service flexibility and reducing healthcare cost. The adoption of management control systems is not only a function of the outcome of a rational decision-making process and institutional pressures but also crucially depends on the characteristics of the individuals ultimately responsible for such decisions. The use of the balanced scorecard facilitates hospitals’ implementation of plans with multiple strategic goals.

Greater than 57% collector efficiency at 50W (47dBm) average output power has been demonstrated while achieving -55dBc linearized ACPR at 5 MHz offset using a 2-carrier-side-by-side WCDMA input signal with 6.5dB peak to average ratio measured at .01% probability on the CCDF. At this condition, the measured overall power-added efficiency is 53%. The HVHBT Doherty exhibits 200W (53dBm) PldBat 70% efficiency with 57% efficiency at 6dB output back-off (OBO) from PldB showing a 25 percentage point improvement over class AB operation.
Elazığ Harput Devlet Hastanesi Çalışanlarında Hepatit B ve C Seroprevalansı (2013)

Aim: To evaluate the seroprevalence of hepatitis B and C infections among health-care workers in Elazig Harput State Hospital. Methods: Hepatitis B and C virus markers (HBsAg, Anti-HBs, AntiHBc IgM, Anti-HBc IgG, Anti-HCV) of 498 health-care persons were retrospectively investigated in this study between July-August 2007 in Elazig Harput State Hospital. Results: A total 20 (4%) health-care workers were positive for HBsAg, 174 (34.9%) for anti-HBs, 4 (0.8%) for anti-HBs as well as anti-HBc IgG, and 2 (0.4%) for anti-HCV. There were no statistical significant differences in point of HBsAg positivity among health-care workers (p>0.05). Anti-HBs positivity was statistically significant high among nurses compared to the others health-care workers (p=0.001). A total 308 (61.8%) health-care workers were seronegative against hepatitis B. Conclusion: The high seronegativity rate against hepatitis B among health-care workers has shown to need to vaccination and education for hepatitis B infection

Modeling Multilevel Structures of Information Technology Acceptance: An Investigation of Group Level Effects on Individual Usage of Web-Based Systems (2005)

Osteonecrosis of the jaw is a potential side effect of certain pharmaceutical agents used in the field of medicine. Early diagnosis and effective management of this condition can be challenging to the clinicians. Bisphosphonates and other anti-angiogenic agents are the most common drugs that are attributed to cause medication-related osteonecrosis of the jaw. In the past, arsenic-based compounds were commonly used local agents for pulp devitalization therapy. Arsenic is also one of the components of the chemotherapeutic regimen in the management of refractory leukemia. Although local diffusion of the arsenic compounds is known to cause osteonecrosis, there are no reports of the same caused by its systemic administration. Here, we present the first ever case of mandibular bone necrosis in a patient with acute promyelocytic leukemia who underwent systemic arsenic trioxide therapy.
Glycerol Uptake Mutants of the Hyphal Fungus Aspergillus nidulans (1988)

A new class of glycerol non-utilizing mutants, designated glcC, has been isolated. The glcC gene was mapped in linkage group VI and mutants were found to complement the reference strains glcA1 (linkage group V) and glcB33 (linkage group I) in diploids. The new mutants were unable to grow on glycerol. However, in contrast to the glcA and glcB phenotype these mutants did grow well on dihydroxyacetone and D-galacturonate. By in vivo 13C NMR spectroscopy it was shown that the glcC mutant did not take up glycerol but did take up dihydroxyacetone. The latter substrate was converted intracellularly into glycerol which was then catabolized as normal.
A second look at the Pomeroy method of tubal sterilization. (1984)

In the 50 years since its initial description, the Pameroy method of tubal sterilization has established itself worldwide as a simple, safe, and sure procedure. The method, entailing a loop in the middle portion of the tube ligated with an absorbale suture and then resected, is readily mastered by 1st-year residents. The minilap Pomerow has made the operation even simpler and shorter, capable of being performed under local anesthesia. The surgical complication rate for the minilap Pomeroy of 0.79% compares favorably with the 2.04% rate for the laparoscopic ring method. In addition, the failure rate for the minilap Pomeroy is 0.3% compared with 0.6% for the laparoscopic ring procedure.
High T<sub>g</sub> fluoranthene-based electron transport materials for organic light-emitting diodes (2015)

Fluoranthene-based thermally stable electron transport materials for organic light-emitting diodes were synthesized and their performance in devices was investigated.
Reductive metabolism and alkylating activity of mitomycin C induced by rat liver microsomes (1981)

Mitomycin C, an antitumor antibiotic, is rapidly metabolized in the presence of rat liver microsomes. NADPH and anaerobic conditions are required for the process. The products isolated after reexposure to air are 2,7-diaminomitosene derivatives. Specifically, in the presence of inorganic phosphate, 1,2-cis- and -trans-2,7-diaminomitosene 1-phosphates, 1,2-cis- and -trans-2,7-diamino-1-hydroxymitosenes, and 2,7-diaminomitosene are formed. The last substance is a new mitomycin C derivative, and proof for its structure is presented. Mytomycin C has been previously postulated to be an alklating agent requiring reduction for activity (Iyer, V. N., & Szybalski, W. (1964) Science (Washington, D.C.) 145, 55]. The 1-phosphates above represent the first chemically characterized bioreductive alkylation products of the drug. 5'-Uridylic acid is alkylated analogously under these conditions, to give cis- and trans-2,7-diaminomitosene 1-(5'-uridylate), while the phosphodiester UpU and uridine itself are inert. Hydrogen gas/PtO2 gives the same results as microsomes/NADPH. The formation of the observed compounds indicates that enzymatic (or chemical) reduction of the quinone system of mitomycin C induces ring opening of the aziridine function, generating a reactive center at the C1 position as previously postulated by others (ibid.). The second alkylating center, also postulated, is not evident, however, under the conditions tested, indicating that the aziridine is the primary bioreductive alkylation function of mitomycin C. Identification of the products and mechanism of the microsomal anaerobic metabolism of mitomycin C are significant in view of the reported toxicity of the drug to anaerobic cancer cells.
Humatopoietic effects of photofrin (2009)

In the presence of visible light, certain naturally-occurring and synthetic non-metallic porphyrins and their derivatives can cause toxic effects within cells. This aspect of these compounds has been harnessed for the elimination of malignant tissue, a therapeutic approach termed photodynamic therapy (PDT). The likelihood that photosensitizing porphyrins might significantly influence the status of tissues other than those targeted by PDT, has not been rigorously investigated. When given to normal male mice, the photosensitizer Photofrin® (dihematoporphyrin ether) produced significant increases in spleen weight, nucleated cell numbers, indices of cell proliferation, and levels of granulocyte-macrophageand erythroid progenitors. Concordant with these changes, was an increase in the number of spleen cells which expressed the receptor (CD71) for the iron transport protein transferrin but no change in expression of the receptor (CD25) for the T cell growth factor interleukin-2, suggesting that the compound had not effected splenic lymphocyte activation. Further flow cytometric studies demonstrated that Photofrin® elevated the number of nucleated spleen cells which expressed antigens recognized by the monoclonal antibody LR-1, the erythroid lineage-specific antibody TER-119, and those that did not express the leukocyte common antigen CD45 or major histocompatibility Class I molecules. The antigen recognized by the LR-1 antibody was subsequently identified as the glycosylphosphatidylinositol-anchoredheat stable antigen (HSA) by enzyme digest, f l ow cytometric and Western immunoblot studies. The increased expression of HSA in the spleens of Photofrin®-treated mice was associated with heightened erythropoiesis in t he organ. Granulopoiesis was the dominant activity in the marrow of mice given Photofrin®. This was represented by a large increase in the proportion of cells which expressed the myeloid-associated Gr-1 and CD11b antigens and a decrease in the proportion of cells which expressed CD71 or the B cell-restricted isofo rm of CD45 (B220). In contrast to Photofrin®, other photosensitizing porphyrins including benzoporphyrin derivative (BPD, verteporfin), hydroxyethyl vinyl deuteroporphyrin, hematoporphyrin IX, and protoporphyrin IX had no discernable hematostimulatory effect. Culture of murine erythroleukemic cells with Photofrin®, but not BPD, increased cell surface CD71 levels and binding of transferrin to these cells, but did not cause erythroid differentiation. Photofrin® also increased surface CD71 expression by non-erythroid P815 mastocytoma cells, suggesting that Photofrin® can influence cellular iron status. Although the mechanism by which Photofrin® influences hematopoiesis was not identified, it nevertheless will be an interesting agent with which to study murine hematopoiesis.

Fluorogenic detection of atypical coliforms from water samples. (1990)

We examined the effectiveness of fluorogen in detecting bacterial enzymes in atypical or injured coliform strains in environmental water samples. 4-methylumbelliferyl-beta-D-galactoside and 4-methylumbelliferyl-beta-D-glucuronide, substrates for beta-galactosidase and beta-glucuronidase respectively, were used as markers for total and faecal coliform bacteria and it was confirmed that fluorogenic assays have a greater sensitivity than reference methods. It was also observed that adding MU-conjugates (50 micrograms/ml) to low selective media for membrane filtration, besides shortening test times, reduces false negative results when detecting sanitary microbial indicators of water pollution.
An investigation of the effect of nurses’ technology readiness on the acceptance of mobile electronic medical record systems (2013)

Continuous educational programs can be provided for nurses to enhance their information technology literacy, minimizing their stress and discomfort about information technology. Further, hospital should recruit, either internally or externally, more optimistic nurses as champions of MEMR by leveraging the instrument proposed in this study. Besides, nurses' requirements must be fully understood during the development of MEMR to ensure that MEMR can meet the real needs of nurses. The friendliness of user interfaces of MEMR and the compatibility of nurses' work practices as these will also greatly enhance nurses' willingness to use MEMR. Finally, the effects of technology personality should not be ignored, indicating that hospitals should also include more employees' characteristics beyond socio-demographic profiles in their personnel databases.

Evaluation of comparative free-radical quenching potential of Brahmi (Bacopa monnieri) and Mandookparni (Centella asiatica) (2011)

Ayurvedic texts describe rejuvenate measures called Rasayana to impart biological sustenance to bodily tissues. Rasayana acting specifically on brain are called Medhya Rasayana. Brahmi is one of the most commonly practiced herbs for the same. Yet there exist a controversy regarding the exact plant species among Bacopa monnieri L. Penn (BM) and Centella asiatica (L.) Urban (CA) to be used as Brahmi in the formulations. Though the current literature available has suggested a very good nootropic potential of both the drugs, none of the studies have been carried out on comparative potential of these herbs to resolve the controversy. Free-radical scavenging potential for these plants is studied to find out their comparative efficacy. The study revealed a very good in vitro free-radical scavenging properties of aqueous and ethanolic extracts of both the plants as evidenced by FRAP, DPPH, reducing power, and antilipid peroxidation assays. It can be concluded from the studies that both the plants, although taxonomically totally different at family level, showed similar type of in vitro activities. The total phenolic and flavonoid contents also revealed a significant similarity in the two plants. The in vitro study supports the Ayurvedic concept of BM and CA having a similar potential.
