Abstract: The stability in real time of two strains of Rhizobium (Rhizobium meliloti andRhizobium japonicum) mixed with different excipients was evaluated during a6-months period. The excipients studied were: peat, peat and calciumcarbonate, zeolite, and ceramic. Liquid cultures and excipients mixtures weredried (12-14% humidity), sealed in plastic bags and preserved at +4oC. Thecells were activated periodically by suspending aliquots from dry products in0.9% saline solution. The viability of Rhizobium cells was evaluated bycultivation of diluted suspensions in YMA plates. The number of viable cells isdecreasing during drying in all cases, increase in the first month of storage,and remains constant or decrease very slowly during storage for all obtaineddry products containing rhizobia mixed with solid dry excipients. The highestnumber of viable cells at the end of the experiment was obtained in ceramicwith Rhizobium japonicum (8x105 cells/gram), and the lowest number ofviable cells was obtained in zeolite with Rhizobium meliloti (1,1x103cells/gram).
Air Pollution Steady-State Advection-Diffusion Equation: The General Three-Dimensional Solution  [PDF]
Daniela Buske, Marco Túllio Vilhena, Tiziano Tirabassi, Bardo Bodmann
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.329131
Abstract: Atmospheric air pollution turbulent fluxes can be assumed to be proportional to the mean concentration gradient. This assumption, along with the equation of continuity, leads to the advection-diffusion equation. Many models simulating air pollution dispersion are based upon the solution (numerical or analytical) of the advection-diffusion equation as- suming turbulence parameterization for realistic physical scenarios. We present the general steady three-dimensional solution of the advection-diffusion equation considering a vertically inhomogeneous atmospheric boundary layer for arbitrary vertical profiles of wind and eddy-diffusion coefficients. Numerical results and comparison with experimental data are shown.

Pharmacology & Pharmacy (PP) , 2014, DOI: 10.4236/pp.2014.56066

Background: the elderly are frequently exposed to drug-related problems and their consequences. Information relating to the appropriateness of the medication used by Romanian elderly is scarce. Objective: to identify the main potential inappropriate prescribing (PIP) instances in a sample of Romanian elderly nursing-home residents, concerning prevalence and subtypes. Methodology: the residents’ medical data were reviewed by a clinical pharmacist considering published geriatric pharmacotherapy recommendations, including four published PIP evaluation tools (the Beers criteria, STOPP-START tools, the PRISCUS list). Results: 91 residents were evaluated; mean age (mean ± SD) was 80.77 ± 6.82 (years), 28 (31%) were ≥85 years old and 58 (64%) had dementia. The median number of diagnoses was 6 (range 2 - 11) and the mean number (±SD) of daily medications was 8.26 (±3.52). An estimated mean (±SD) of 2 (±1.41) PIP per resident was identified, with 117 misuse-PIP (46.24%), 60 underuse-PIP (23.72%), 41 lack of monitoring-PIP (16.21%) and 35 overuse-PIP (13.83%). The most frequent PIP subtypes were the use of nonsteroidal anti-inflammatory drugs as chronic analgesic treatment in osteoarthritis (29.67%), underuse of fall prevention (100%) and analgesic therapies (23.08%), overuse of nootropic medications (26.98%) and lack of annual creatinine assessment (30.77%). Conclusion: a more geriatric-oriented care seemed to be necessary, but larger studies are needed to confirm these findings.

Transient defects of mitotic spindle geometry and chromosome segregation errors
William T Silkworth, Daniela Cimini
Cell Division , 2012, DOI: 10.1186/1747-1028-7-19
Abstract: Mitosis, the process by which a single eukaryotic cell partitions its genetic material, has fascinated scientists for over a century, and already in the late 1800s Walther Flemming described the processes of chromosome segregation and cell division with exquisite detail [1,2]. Four main structures, consisting of centrosomes, a microtubule-based mitotic spindle, kinetochores, and chromosomes [3,4], cooperate to form the mitotic apparatus (Figure 1A) in vertebrate somatic cells. The centrosomes are specialized organelles, each consisting of a pair of centrioles and pericentriolar material, and they play a key role in mitotic spindle assembly by serving as the primary sites of microtubule nucleation [5,6]. Molecular motors act to move the replicated centrosomes to diametrically opposing positions around the nucleus [7-9] (Figure 1A, Prophase), thus ensuring assembly of a fusiform and symmetric microtubule-based mitotic spindle once the nuclear envelope breaks down. At the same time, within the nucleus, the chromosomes undergo significant condensation (Figure 1A, Prophase) while kinetochores assemble on the centromeric region of each sister chromatid of the replicated chromosomes (reviewed in [10]). Upon nuclear envelope breakdown, which marks the beginning of prometaphase, the kinetochores become available for capture by dynamically searching microtubules (Figure 1A, Prometaphase). The kinetochore is a large protein complex that constitutes the attachment site for microtubules of the mitotic spindle on each chromatid [11]. In addition to acting as attachment sites for microtubules, kinetochores are also part of a signaling pathway, termed the spindle assembly checkpoint (SAC), that facilitates the coordinated and accurate segregation of chromosomes by preventing anaphase onset until all kinetochores are bound to microtubules (reviewed in [12]). As mitosis progresses, chromosomes establish attachments with microtubules and undergo poleward and anti-poleward movements, w

Abstract: the discovery of sexuality by adolescent girls living in the streets generally involves lack of knowledge about their own bodies, often resulting in risk behaviors for sexually transmitted diseases and pregnancy. this study aimed to identify the meanings ascribed to motherhood by teenage girls with a history of living in the streets and who chose to assume the care for their children, off the streets. based on a qualitative methodology, data were collected from the adolescent mothers at a nongovernmental shelter and analyzed according to the content analysis modality. the results were discussed using the category "new life: mother & child", showing that the adolescents ascribed a positive meaning to motherhood, with the child seen as both a "savior" from the mother's certain death on the streets and a repository for the mother's expectations for a better future. the article concludes by analyzing motherhood as an opportunity for establishing new ways of being in (and relating to) the world, with the construction of this motherhood process as a potentially fertile ground for intervention by health professionals.

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.48A1003

Air pollution transport and dispersion in the atmospheric boundary layer are modeled by the advection-diffusion equation, that is, essentially, a statement of conservation of the suspended material in an incompressible flow. Many models simulating air pollution dispersion are based upon the solution (numerical or analytical) of the advection-diffusion equation assuming turbulence parameterization for realistic physical scenarios. We present the general time dependent three-dimensional solution of the advection-diffusion equation considering a vertically inhomogeneous atmospheric boundary layer for arbitrary vertical profiles of wind and eddy-diffusion coefficients. Numerical results and comparison with experimental data are shown.

Synthesis of polyacrylamide in aqueous solution: solubility

Orbital : the Electronic Journal of Chemistry , 2012,
Abstract: The synthesis of aqueous polyacrylamide solution was evaluated for its solubility in water. The reactions were performed using the acrylamide monomer, solvent and initiator (K2S2O8), with the system under magnetic stirring and heating (60°C) for 4 hours. The assays have been made in proportions below of the acrylamide solubility limit. However, using only water as solvent the reaction was not promising. This is because as the polymer forming it was occurring the medium gelatinization. To overcome this situation used was a mixture water/ethanol in the following proportions: 90/10, 80/20, 70/30, 60/40, respectively. Nevertheless, only achieved success in water/ethanol 60/40, where the polymer had formed was soluble at the end of the reaction. The polyacrylamide obtained was purified by precipitation in acetone, and subsequent dissolution in water and reprecipitation in methanol, with 98% yield. The characterization of the reaction was done by FTIR, identified in which the disappearance of the bands 986, 960 and 840 cm-1 of the own terminal vinyl group of the acrylamide monomer. Moreover, was observed the presence of the band at 732 cm-1 related angular deformation of chain, -(CH2)n- for n>3. The polyacrylamide obtained is the subject of future studies of modification and in chelation applicability.

Abstract: The aim of this work is to analyze the viability of microorganisms from Collection ofIndustrial Microorganisms from Faculty of Animal Science and Biotechnology –Timisoara, during freezing and thawing as part of cryopreservation technique. Thestability in real time of 19 strains cryopreserved in 16% glycerol was evaluatedduring a 6-months period. The strains studied were: Escherichia coli, Lactobacillusacidophilus, Rhizobium meliloti, Saccharomyces cerevisiae, Aspergillus oryzae,Aspergillus niger, Trichoderma viride, Bacillus globigii, Bacillus licheniformis, and9 strains of Bacillus subtilis. The strains cryopreserved at -20oC and -70oC wereactivated using the fast thawing protocol. A better cell recovery was achieved withthe -70oC protocol reaching an average viability for E. coli of 86,3%, comparingwith 78,6% in -20oC protocol. The cell recovery percentages for the other strainswere: 92,4% for L. acidophilus, 93,9% for A.niger, 89% for A. oryzae, 86,7% for T.viride, 94,2% for R. meliloti, 82,1% for S. cerevisiae, 89,9% for B. licheniformis.Regarding the viability of genetically modified microorganisms, the values shows agood recovering after freezing and thawing, even after 180 days of cryopreservation.With the -20oC protocol lower viability was observed due probably to the formationof eutectic mixtures and re-crystalization processes
