In vitro enhanced accumulation of polyphenols during somatic embryogenesis in Plantago ovata Forsk

Plantago ovata Forsk (common isabgul) is much known for its medicinal importance. It is a potential source of bioactive compounds like polyphenols which serve as natural antioxidant having an ability to quench cytotoxic free radicals that are preventive to many diseases. In present investigation, the accumulation of polyphenolic compounds was studied during in vitro somatic embryogenesis in Plantago ovata. Calli of three different developmental stages during somatic embryogenesis were selected for this purpose and total polyphenol content was determined spectrophotometrically using FolinCiocalteu reagent. The embryogenic calli were found to contain highest level of polyphenolics. Further, the effect of exogenous additives like casein hydrolysate and coconut water on the accumulation of total polyphenol was also included into the study. 42 days old calli were treated with different concentrations of casein hydrolysate (1 gL-1, 2 gL-1, 3 gL-1) and coconut water (5%, 10%, 15%) and used for total polyphenol content determination. 2 gL1 casein hydrolysate and 5% coconut water produced the best result. So the study shows a greater promise in advancing the use of Plantago ovata for producing phenolic compounds in a larger scale.

Ground state cooling in a bad cavity

We study the mechanical effects of light on an atom trapped in a harmonic potential when an atomic dipole transition is driven by a laser and it is strongly coupled to a mode of an optical resonator. We investigate the cooling dynamics in the bad cavity limit, focussing on the case in which the effective transition linewidth is smaller than the trap frequency, hence when sideband cooling could be implemented. We show that quantum correlations between the mechanical actions of laser and cavity field can lead to an enhancement of the cooling efficiency with respect to sideband cooling. Such interference effects are found when the resonator losses prevail over spontaneous decay and over the rates of the coherent processes characterizing the dynamics.

PERSONALITY DIMENSION AND ITS RELATIONSHIP TO ON-THE-JOB PERFORMANCE

This study was conducted to determine the relationship between personality dimensions and OJT performance of the BS Information Technology and BS Information Systems graduating students of a state university in the Philippines. Descriptive method of research was used. The participants of this study are the 73 Fourth Year BS Information Technology and 43 BS Information Systems students. A standardized questionnaire on The Five-Factor of Personality Dimensions Model as conceptualized by Costa and McCrae (1992) was used to determine the personality dimensions of the respondents. To determine the OJT Performance of the respondents, a questionnaire on OJT Performance Rating was used. The results of the study shows that the level of the personality dimensions of the respondents in the areas of Neuroticism, Extroversion, Openness to Experience, Agreeableness, Conscientiousness as a whole shows acceptable performance levels and when they are grouped according to course. The level of the OJT performance of the respondents when taken as a whole and when they are grouped according to course are all found to be above average performance levels. There is significant difference between each of the personality dimensions and OJT performance of the respondents when they are grouped according to course and OJT performance of the respondents.

Wavelet Domain Image Super-Resolution Reconstruction Based on Image Pyramid and Cycle-Spinning

On the base of the analysis of single image super-resolution reconstruction, wavelet domain super-resolution reconstruction based on image Pyramid and cycle-spinning is proposed in the paper. The algorithm consists of the following parts: the predictive high-resolution image are obtained by a LR image based on laplacian pyramid method; the discrete wavelet transform is used for predictive high-resolution image to obtain the high-frequency wavelet coefficients; a high-resolution image is obtained by the inverse wavelet transform; Finally the cycle-spinning method is used to reduce ringing. The proposed algorithm avoids the application of iterative method, reduces the complexity of calculation and applies to large dimension low-resolution images. The results show the proposed approach has succeeded in obtaining a high-resolution image with a high peak signal-to-noise ratio and good visual quality.

The Art of Revolutionary Praxis

Merleau-Ponty, in Humanism and Terror (1947), addresses the spectrum of problems related to revolutionary action. His essay, Eye and Mind (1960), is best known as a contribution to aesthetics. A common structure exists in these apparently disparate works. We must reject the illusion of subjective clairvoyance as a standard of revolutionary praxis; but also we must reject any idealised light of reason that illuminates all—that promises a history without shadows. The revolutionary nature of an act must be established as such through praxis . The creative praxes of the political revolutionary or the revolutionary artist are recognised ex post facto ; yet each involves the creation of its own new aesthetic wherein the value of that praxis is to be understood spontaneously and all at once.

Biological optimization of the dose in pancreatic cancer.

In the last decades, many attempts were made to optimize the biological effect of RT in the treatment of pancreatic carcinoma. The use of combined radiotherapy and chemotherapy was certainly successful, with the most promising results achieved with the combination of several drugs with RT or with innovative modalities of administration of concomitant chemotherapy. A dose effect in resected tumors seems suggested by some studies; while the use of high doses in inoperable tumors did not result in significant advantages in terms of response and outcome, a significant correlation between dose and toxicity was observed. Altered fractionations were not studied systematically, though an accelerated-hypofractionated (30 Gy in 10 fractions) treatment is indicated as feasible in combination with concomitant chemotherapy with results similar to those achieved with conventional fractionations and a markedly shorter duration. Based on the small improvements recorded in the treatment of these tumors, the evaluation of newer treatment modalities seems justified.

High-field magnetoresistance at interfaces in manganese perovskites

The low-field (LFMR) and high field (HFMR) magnetoresistance response of ceramic ${\mathrm{La}}_{2/3}{\mathrm{Sr}}_{1/3}{\mathrm{MnO}}_{3}$ (LSMO) samples having grain sizes diameters \ensuremath{\emptyset} ranging from 10 \ensuremath{\mu}m to 20 nm have been investigated. A limiting LFMR of about \ensuremath{\approx}30% is obtained for the \ensuremath{\emptyset} \ensuremath{\approx}0.5 \ensuremath{\mu}m but no larger values are obtained by further reduction of the grain size down to the nanometric range. On the contrary, the HFMR progressively rises when reducing the grain size. Magnetic and transport measurements suggest that HFMR originates from the existence of a noncollinear surface layer, having a thickness t that increases when reducing \ensuremath{\emptyset}. We have disclosed a clear relationship between the thickness, the intergranular resistance, and the height of the surface energy barrier. In addition, we show that in samples with submicronic grains, there is an intergranular Coulomb gap.

How many nations are we able to imagine?

Who sings the Nation-State in Guinea-Bissau? I will try to answer this and other questions by putting two films into dialogue. The first one is En Nations Födelse (The Birth of a Nation), a film shot by Lennart Malmer and Ingela Romare in Guinea-Bissau in 1973. The second one is a reel sequence, a film fragment that documents the 10th World Festival of Youth and Students which took place in East Berlin in 1973 and where several nations that still did not exist on a political level sought to assert themselves on a symbolical level. The sequence was filmed by Guinean director Sana N’Hada. If the first one was made by two foreigners who were engaged in the liberation struggle in Guinea-Bissau, the second one was shot by a Guinean director who was in East Germany in order to represent his country, then on its way to becoming an independent state. Both films seek to activate mechanisms for the construction of Guinea-Bissau as a nation-state, sharing ideological repercussions. I do not take them as images of the past, but rather as a projected future in an idealized past. A future conjugated in the imperfect, a future imperfective.

Response of grain yield and yield components of promising genotypes of spring rapeseed (Brassica napus L.) under non-stress and moisture-stress conditions

To assess moisture stress tolerance at the reproductive growth stage in 11 promising genotypes of spring rapeseed (Brassica napus L.), two field experiments were conducted in two growing seasons (2008-2010) at the Agricultural Research Center of Safiabad, Dezful, Iran. Genotypes were sown under two non-stress (well-irrigated) and moisture stress (irrigation ceased at flowering) conditions using a randomized complete block design with three replications for each moisture regime. Agronomic traits (plant height, number of siliques per plant, number of grains per silique, test grain weight, grain yield, days to flowering, days to maturity and oil content) were measured and recorded. Genotype and moisture regime main effects were highly significant for all the measured traits. Moisture regime × genotype interaction was also highly significant for silique per plant, flowering period and oil content traits, suggesting different responses of genotypes in different moisture conditions. Grain yield reduction (10.9%) in genotype 5 (G5) under moisture stress conditions was significantly lower than in all other genotypes. Genotype 11 (G11) produced the highest oil content, which was significantly higher than that produced by other genotypes in either regime. A significant positive correlation coefficient (r = 0.578*) was observed between grain yield and oil content under non-stress conditions. Grains silique-1 had a significant negative correlation with date of maturity under well-watered (r = -0.711**) and moisture stress (r = -0.634*) conditions. Calculated stress tolerance index (STI)varied from 0.47 for G7 to 1.01 for Hyola401. G1 and G4 with high STI values were identified as highly tolerant genotypes. This was in agreement with conclusions reached based on agronomic traits. It is concluded that G1 with 1974 kg ha-1 and G4 with 2511 kg ha-1 grain yields could be suitable substitutes for cv. Hyola401 under moisture stress and non-stress conditions, respectively.

Final Technical Report

Using current methods, oil and gas in the subsurface cannot be reliably predicted from seismic data. This causes domestic oil and gas fields to go undiscovered and unexploited, thereby increasing the need to import energy. The general objective of this study was to demonstrate a simple and effective methodology for estimating reservoir properties (gas saturation in particular, but also including lithology, net to gross ratios, and porosity) from seismic attenuation and other attributes using P and S-waves. Phase I specific technical objectives: â¢ Develop Empirical or Theoretical Rock Physics Relations for Qp and Qs â¢ Create P-wave and S-wave Synthetic Seismic Modeling Algorithms with Q â¢ Compute P-wave and S-wave Q Attributes from Multi-component Seismic Data All objectives defined in the Phase I proposal were accomplished. During the course of this project, a new class of seismic analysis was developed based on compressional and shear wave inelastic rock properties (attenuation). This method provides a better link between seismic data and the presence of hydrocarbons. The technique employs both P and S-wave data to better discriminate between attenuation due to hydrocarbons versus energy loss due to other factors such as scattering and geometric spreading. It was demonstrated that P and S attenuation can be computed from well log data and used to generate synthetic seismograms. Rock physics models for P and S attenuation were tested on a well from the Gulf of Mexico. The P and S-wave Q attributes were computed on multi-component 2D seismic data intersecting this well. These methods generated reasonable results, and most importantly, the Q attributes indicated gas saturation.

Genetic Diversity of Rabbit (Oryctolagus cuniculus) Population in South Eastern Nigeria Using Microsatellite Markers

A study was conducted to estimate the diversity that exists among three rabbit populations adapted to the South-Eastern part of Nigeria. Blood samples were collected from 75 matured, mixed-sex, and unrelated three rabbit breeds selected across the zone. Eight microsatellites (Sol30, Sol33, and Sol44, Sat3, Sat7, Sat8, Sat12, and INRA) markers were used for the study. These microsatellites were uniformly distributed among rabbit genomes for genotyping. Subsequently, genetic variability within and between breeds was calculated. Allelic frequencies and Hardy-Weinberg equilibriums as well as Analysis of Molecular Variance, were also estimated using GenAlEX 6.41 software. Discriminant Analysis of Principal Components (DAPC) for the population structure of the rabbit breeds was performed in R v.3.5.0 using the R package adegenet. All the 8 loci amplified in this study were found to be 100% polymorphic, the observed allele sizes and their frequencies for the microsatellite markers in every three breeds showed that the highest frequency was 0.330 for the allele with the size of 470bp at Sol33 locus in New Zealand White (NZW) rabbits. The Nei’s genetic identities and distances between Chinchilla (CHI) and Dutch (DUT), CHI and NZW, DUT and NZW obtained in this study were [0.173, 0.185, and 0.189] and [1.753, 1.689, and 1.666] respectively. The dendrogram and biplot revealed that the three breeds were identified at two separate clusters. In addition, the admixture level of an individual rabbit among the three breeds indicated that the breeds were not pure and also the existence of more polymorphism within the breed than among the breed diversity.

A national follow‐up survey of <scp>UK</scp> graduates opinion of undergraduate oral surgery teaching

Abstract Introduction A national follow‐up survey was undertaken to determine whether dental graduates from 2009 perceived that their undergraduate oral surgery education had equipped them for general dental practice 4 years after graduating. Materials and Methods Graduates from the same 13 United Kingdom dental schools who had taken part in the original survey were invited to take part in this follow‐up online survey. Their contact details were identified via the general dental council register, social media and alumni groups. Results In total, 161 responded (2009b) which represents 16% of the graduates of the original survey in 2009a. A similar percentage of these respondents perceived that the teaching in oral surgery had given them sufficient knowledge to undertake independent practice (83% and 79% in 2009a and 2009b, respectively). Most respondents (99% in both years) reported confidence in undertaking simple forceps exodontia. Confidence in surgical exodontia was poor in both surveys, but one area that appeared improved in the follow‐up related to the sectioning of teeth (84% in 2009b compared with 49% in 2009a). Areas of weakness identified in 2009 were reported to be improved in the follow‐up. Conclusion This follow‐up survey supports the findings of the original survey. Future longitudinal studies would allow institutions to identify possible weaknesses in their curriculum and to track the career development of their graduates and facilitate robust data collection.

Tropheryma whipplei Endocarditis: Case Presentation and Review of the Literature

Abstract Whipple’s disease is a rare infective condition, classically presenting with gastrointestinal manifestations. It is increasingly recognized as an important cause of culture-negative endocarditis. We present a case of Whipple’s endocarditis presenting with heart failure. A literature review identified 44 publications documenting 169 patients with Whipple’s endocarditis. The average age was 57.1 years. There is a clear sex predominance, with 85% of cases being male. Presenting symptoms were primarily articular involvement (52%) and heart failure (41%). In the majority of cases, the diagnosis was made on examination of valvular tissue. Preexisting valvular abnormalities were reported in 21%. The aortic valve was most commonly involved, and multiple valves were involved in 64% and 23% of cases, respectively. Antibiotic therapy was widely varied and included a ceftriaxone, trimethoprim, and sulfamethoxazole combination. The average follow-up was 20 months, and mortality was approximately 24%. Physician awareness is paramount in the diagnosis and management of this rare condition.

The Role of Structural Inequality on COVID-19 Incidence Rates at the Neighborhood Scale in Urban Areas

The lockdown policies enacted in the spring of 2020, in response to the growing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, have remained a contentious policy tool due to the variability of outcomes they produced for some populations. While ongoing research has illustrated the unequal impact of Coronavirus disease (COVID-19) on minority populations, research in this area has been unable to fully explain the mechanisms that produce these findings. To understand why some groups have been at greater risk of contracting COVID-19, we employ structural inequality theory to better understand how inequality may impact disease transmission in a pandemic. We used a novel approach that enabled us to focus on the microprocesses of structural inequality at the zip code level to study the impact of stay-at-home pandemic policies on COVID-19 positive case rates in an urban setting across three periods of policy implementation. We then analyzed data on traffic volume, income, race, occupation, and instances of COVID-19 positive cases for each zip code in Salt Lake County, Utah (USA) between 17 February 2020 and 12 June 2020. We found that higher income, percent white, and white-collar zip codes had a greater response to the local stay-at-home order and reduced vehicular traffic by nearly 50% during lockdown. The least affluent zip codes only showed a 15% traffic decrease and had COVID-19 rates nearly 10 times higher. At this level of granularity, income and occupation were both associated with COVID-19 outcomes across all three stages of policy implementation, while race was only predictive of outcomes after the lockdown period. Our findings illuminate underlying mechanisms of structural inequality that may have facilitated unequal COVID-19 incidence rates. This study illustrates the need for more granular analyses in policy research and adds to the literature on how structural factors such as income, race, and occupation contribute to disease transmission in a pandemic.
