Antimicrobial Activities and Phytochemical Screening of Citrus Aurantifoila (Lime) Leaf Extracts and Fruit Juice on Some Microorganisms

: This work studies the antimicrobial activities and phytochemical constituents of Citrus aurantifoila (lime) leaf extracts and fruit juice on some microorganisms. The antimicrobial activities and minimum inhibitory/ minimum bacteriocidal/fungicidal concentrations (MIC/MBC/MFC) of ethanolic, methanolic and aqueous extracts of Citrus aurantifolia leaves and fruits juice were determined on some pathogenic microorganisms namely: Staphylococcus aureus, Escherichia coli, Psuedomonas aeruginosa, Pseudomonas aeruginosa (ATCC 27853) and Trichophyton rubrum using agar well diffusion method. The methanolic extract was found to show more activity than the ethanolic and aqueous extract on all the isolates except for E.coli that showed resistance to all the extracts. The inhibition zone diameters (IZD) of methanol, ethanol and aqueous extracts ranged between 5 and 23 mm, 4 and 14 mm and 4 and 11mm respectively. The MICs of ethanolic extracts were 0.76 mg/ml for Staphylococcus aureus, 200 mg/ml for Escherichia coli, 1.56 mg/ml for Pseudomonas aeruginosa, 0.76 mg/ml for Pseudomonas aeruginosa (ATCC 27853) and 50 mg/ml for Trichophyton rubrum. The MICs of methanolic extract were 0.76 mg/ml for Staphylococcus aureus, 200 mg/ml for Escherichia coli, 1.56 mg/ml for Pseudomonas aeruginosa, 0.76 mg/ml for Pseudomonas aeruginosa (ATCC 27853) and 25 mg/ml for Trichophyton rubrum. The MICs of aqueous extract were 0.76mg/ml for Staphylococcus aureus, 200 mg/ml for Escherichia coli, 1.56 mg/ml for Psuedomonas aeruginosa and Psuedomonas aeruginosa (ATCC 27853) and 100mg/ml for Trichophyton rubrum. The MBC/MFC ranged from 3.125 mg/ml to 12.5 mg/ml for all organisms tested. The standard control antibiotic/antifungal (ciprofloxacin/fluconazole) showed comparable results with the plant extracts. The phytochemical analysis carried out on the plant extracts revealed the presence of saponins, flavonoids, steroids, alkaloids, tannins, glycosides and reducing sugars. Statistical analyses showed that there were significant differences in the antimicrobial activities of each extract on the test organisms. The presence of these phytochemicals supports the use of this plant as antimicrobial agent and thus can be used in the treatment of some infections caused by these tested pathogenic microorganisms.
Biometric evaluation of Passiflora cincinnata seeds obtained from the herbaceous extract of the caatinga biome

Seed biometrics is an important tool to detect genetic variability within populations of the same species. In this sense, the objective was to evaluate biometric evaluation of Passiflora cincinnata seeds obtained from the herbaceous extract of the caatinga biome. The work was developed at the Federal Rural University of the Semi-arid, Mossoró, Brazil, in the year 2019. 300 units of seeds of various genotypes of Passiflora cincinnata were collected, in an area of the herbaceous extract of the caatinga biome, where the following were evaluated characteristics: a) morphological characterization of Passiflora cincinnata, determining the length and width of 300 seeds, with the help of a caliper, being expressed in millimeters b) thickness of the seeds, being expressed in millimeters; and c) seed weight, expressed in grams. There was a regular degree of symmetry for the frequency distributions of the length, width, thickness, length/width ratio and weight of Passiflora cincinnata seeds, being different from zero. A degree of flattening or kurtosis of the platicurtic and leptocurtic type was found for the evaluated characteristics. Responses from scientific research on descriptive measures of location, variability or scale, asymmetry and kurtosis may serve as a basis for future studies of descriptive analysis and statistical inference, for comparison of different environments, genetic studies and plant breeding, as well as in construction of the so-called variance components, for simulation and modeling studies applied to agriculture. Keywords— Wild passion fruit, Descriptive statistics, Inference.
Semi-Supervised Learning-Based Calibration Model Building of NIR Spectroscopy for In Situ Measurement of Biochemical Processes Under Insufficiently and Inaccurately Labeled Samples

To deal with the typical problem of inaccurately and insufficiently labeled samples involved with real measurement of biochemical process components, a semi-supervised learning-based calibration model building method is proposed to use the up-to-date near-infrared (NIR) spectroscopy for in situ measurement of such a process. First, a supervised ladder network is designed to delete the inaccurately labeled samples, such that a cleaned training set is used for establishing the NIR calibration model. To address the issue of insufficiently labeled samples for modeling with the aim of online measurement, a semi-supervised ladder network is explored to establish a regression learning algorithm, by representing the process characteristics from all the unlabeled samples in combination with the cleaned labeled samples. In the ladder network, encoding is used to extract the features and decoding is used for denoising. Meanwhile, the skip connections allow higher layers to concentrate on those features related to the regression task, therefore facilitating the model accuracy. A numerical example and experiments on a glucose fermentation process are shown to demonstrate the effectiveness and advantage of the proposed method.
Estimulación Ovárica Controlada para Inseminación Intrauterina, una revision

La inseminación intrauterina es una de las técnicas más utilizadas en el manejo de la infertilidad. Sus indicaciones van desde ciclos anovulatorios o factor masculino leve, hasta parejas del mismo sexo o mujer soltera. Desde sus inicios, se han descrito diversos protocolos de estimulación ovárica. Probablemente el más utilizado sea el uso de clomifeno vía oral, debido a lo sencillo, económico y disponibilidad del mismo. No obstante, las nuevas tecnologías y el uso de gonadotropinas urinarias o recombinantes, han permitido mejorar los resultados en aquellos casos donde se observa una resistencia al clomifeno. La decisión sobre cuál es el mejor protocolo para una estimulación ovárica en inseminación intrauterina, no se basa simplemente en buscar el mejor fármaco, se deben considerar factores como el diagnóstico, la presencia o no de ciclos ovulatorios, el coste y disponibilidad de los medicamentos, entre otros. Es el propósito de este trabajo, realizar una revisión de las indicaciones y resultados para poder establecer y/o sugerir pautas de manejo.
Time-series InSAR Analysis and Post-processing Using ISCE-StaMPS Package for Measuring Bridge Displacements

This study aims to monitor the displacement of the bridges using Stanford Method for Persistent Scatterers (StaMPS) time-series Persistent Scatterer Interferometric Synthetic Aperture Radar analysis. For case study bridges: Kimdaejung bridge and Deokyang bridge, we acquired 60 and 33 Cosmo-Skymed Synthetic Aperture Radar (SAR) data over the Mokpo region and Yeosu region, respectively from 2013 to 2019. With single-look interferograms, we estimated the long-term time-series displacements over the bridges. The timeseries displacements were estimated as -8.8 mm/year and -1.34 mm/year at the mid-span over the selected bridges: Kimdaejung and Deokyang bridge, respectively. This time-series displacement provides reliable and high spatial resolution information to monitor the structural behavior of the bridge for preventing structural behaviors.
Proof-of-Concept of High-Pressure Torrefaction for Improvement of Pelletized Biomass Fuel Properties and Process Cost Reduction

This paper provides a comprehensive description of the new approach to biomass torrefaction under high-pressure conditions. A new type of laboratory-scale high-pressure reactor was designed and built. The aim of the study was to compare the high-pressure torrefaction with conventional near atmospheric pressure torrefaction. Specifically, we investigated the torrefaction process influence on the fuel properties of wooden-pellet for two different pressure regimes up to 15 bar. All torrefaction processes were conducted at 300 °C, at 30 min of residence time. The initial analysis of the increased pressure impact on the torrefaction parameters: mass yields, energy densification ratio, energy yield, process energy consumption, the proximate analysis, high heating value, and energy needed to grind torrefied pellets was completed. The results show that high-pressure torrefaction needed up to six percent less energy, whereas energy densification in the pellet was ~12% higher compared to conventional torrefaction. The presence of pressure during torrefaction did not have an impact on the energy required for pellet grinding (p < 0.05).
Bioefficacy of some insecticides against tobacco caterpillar, Spodoptera litura (Fabricius) under lab conditions

The bioefficacy of five insecticides viz. Fipronil, Indoxacarb, Flubendiamide, Spinosad and Lambda cyhalothrin were conducted under lab condition by leaf dip method to determine their stomach toxicity against Spodoptera litura and the results revealed that at 24 HAE (hours after exposure) Indoxacarb (LC50 = 0.22 ppm) was the most toxic whereas Lambda cyhalothrin (LC50 = 350 ppm) was the least toxic and the order of toxicity was: Indoxacarb > Fipronil > Spinosad > Lambda cyhalothrin. Similar trends were observed at 48 HAE where the order of toxicity was Indoxacarb > Flubendiamide > Fipronil > Spinosad > Lambda cyhalothrin. The LC values indicated that Indoxacarb was most toxic (LC30 = 0.052 ppm; LC50 = 0.096 ppm; LC90 = 0.43 ppm) closely followed by Flubendiamide (LC30 = 0.3 ppm; LC50 = 0.8 ppm; LC90 = 7.2 ppm) whereas the least toxic insecticide was Lambda cyhalothrin (LC50 = 225 ppm). A comparative dose mortality response indicated in terms of relative toxicity (RT) indicated that at 72 HAE, Indoxacarb (RT 50 = 2960) was still the most toxic insecticide followed by Fipronil (RT 50 = 30.94) and Lambda cyhalothrin (RT 50 = 1.00).

Seagrass wasting disease along a naturally occurring salinity gradient

In the 1930s, outbreaks of the wasting disease pathogen Labyrinthula zosterae caused a severe reduction of the eelgrass Zostera marina meadows in the Atlantic Ocean. Many surviving populations were found in low-salinity environments, and low-salinity environments have therefore been hypothesized to act as a refuge for eelgrass against L. zosterae infection. Here, we investigated L. zosterae pathogen load and wasting disease symptoms in eelgrass over a ~970 km salinity gradient (6−25 PSU) along the Swedish coast. Furthermore, laboratory infection experiments and studies of inhibitory compounds were carried out to investigated whether resistance against the pathogen is correlated to differences in natural pathogen pressure among eelgrass populations. The degree of L. zosterae infection was positively correlated to salinity and the pathogen was absent in several of the eelgrass meadows in lower salinity (7−8 PSU). However, a low L. zosterae pathogen load was also found in some eelgrass populations in the lowest salinity (6 PSU). No correlation between resistance and pathogen pressure in situ was detected, and all eelgrass shoots produced chemical compounds that inhibited L. zosterae growth. These results imply that positive correlations between L. zosterae and salinity are not due to eelgrass resistance, but rather to the poor ability of L. zosterae to cope with low salinity. However, our results also indicate that some strains of L. zosterae may adapt to low salinity, and therefore there may also be a risk of wasting disease outbreaks in low-salinity eelgrass meadows, in contrast to what so far has been the general hypothesis.
Analytical Synthesis of Fully Canonical Cascaded-Doublet Prototype Filters

This letter presents an analytical procedure for the synthesis of a low-pass prototype filter constituted by the cascade of doublet blocks coupled by inverters or shunt reactances. The considered doublet is a second-order resonating structure composed of two resonant and two nonresonant nodes which allow the placement of two finite transmission zeros (TZs) in the frequency response. The considered configuration allows realizing compact fully canonical filters with the maximum number of TZs (the doublets are typically implemented through dual-mode cavities). The proposed procedure introduces for the first time an analytical procedure for synthesizing the low-pass prototype of the cascaded-block topology, overcoming the time consuming and inaccurate procedures currently based on numerical optimization. Two synthesis examples are presented to validate the novel synthesis procedure.
Overload Distribution Transformer With Natural Ester and Aramid-Enhanced Cellulose

The load of a distribution transformer can be daily or seasonal fluctuant, which submits the transformer to the risk of overload through thermal stress. In this research, it is demonstrated that the aramid-enhanced cellulose in natural ester, as a high-temperature insulation system, is a solution by which the overload capability of a transformer can be improved. First, the thermal and ageing model stipulated in IEEE C57.91 Annex G, which was proposed to evaluate the Kraft and thermally upgraded Kraft, has been modified to incorporate the ageing rate benchmark derived from Arrhenius law, so the improved model can now cover various combinations of insulation systems. The top liquid temperatures, hot spot temperatures and equivalent ageing factors of transformers with aramid-enhanced cellulose in natural ester and Kraft in mineral oil under different load scenarios generated from field loading data were analyzed. The results showed that the overloading capability of the transformer with aramid-enhanced cellulose was improved, as its equivalent ageing factor was 13 percent of the equivalent ageing factor of the transformer with Kraft under the heavy overload scenario. Furthermore, an overloading test and field test were also conducted for a prototype transformer with aramid-enhanced cellulose and natural ester. The measured top liquid temperature and hot spot temperature and the calculated equivalent ageing factor after the overloading test verified that the transformer with aramid-enhanced cellulose operated well below the safety thresholds. Additionally, the results from the transformer upon installation in the field proved that the transformer also operated well under an overloading status.
Comparison of Some Biomechanical Properties of Tibiotarsus in Four Different Feather Color Lines of 60-Day Old Female Quails

17/October/2019 Approved: 03/April/2020 ABSTRACT This study aimed to compare some morphological and mechanical measurements of four different color female quails to contribute to the formation of the morphological database. Quails are the smallest farmed avian species which are becoming more important for the poultry industry. They are also used as experimental animals and are valuable birds for researches. Genetic factors are important determinants of bone strength. Thus, skeletal disorders may be reduced by breeding selection in quails. Forty female quails with four different feather colors, including wild, white, yellow, and black, were compared at 60 days of age. Each quail group contained ten individuals. A three-point bending test was performed with a custom-made testing machine designed for low strength materials. No significant difference was found between the groups in terms of body weight. The tibiotarsus weight in wild and black (0,665±0,055g and 0,687±0,025g, respectively) was significantly lower than in the others but, the significant highest value was in white quails (0,758±0,063g) ( p =0.001). Significantly shorter tibiotarsus was observed in the black quails (51,286±1,374mm), while the tibiotarsi of the white and yellow quails were the tallest (53,216±1,796mm and 53,083±1,092mm, respectively) ( p =0.005). There were no significant differences among the groups in the biomechanical properties of tibiotarsus, except stiffness. Stiffness was the highest in the white quails (109,500±3,807 N/mm) and the lowest in the black quails (99,000±9,498 N/mm) ( p =0.042). In conclusion, white quails have been observed to have relatively better bone biomechanical properties compared to the other color groups at 60
Biweekly cladribine and rituximab in a patient with hairy cell leukemia and severe renal failure

Hairy cell leukemia (HCL) is a rare indolent lymphoproliferative disorder usually clinically characterized by pancytopenia and splenomegaly. It is very sensitive to purine analogues cladribine and pentostatin which are both primarily excreted by kidneys and registration labels bear warnings against their use in patients with severe renal insufficiency. We report a patient with HCL and severe renal failure who was successfully treated with five subcutaneous injections of cladribine 0.14 mg/ kg and six biweekly infusions of rituximab 375 mg/2 iv. This regimen was tolerated remarkably well without cumbersome side–effects. Our case-report suggests that cladribine can be efficaciously and safely used in patients with severe renal insufficiency if administered in standard doses once every two weeks.
A Novel 3D UAV Channel Model for A2G Communication Environments Using AoD and AoA Estimation Algorithms

In this article, we propose a three-dimensional (3D) multi-input multi-output (MIMO) channel model for air-to-ground (A2G) communications in unmanned aerial vehicles (UAV) environments, where the UAV transmitter and ground receiver are in motion in the air and on the ground, respectively. A novel angular estimation algorithm is proposed to estimate the real-time azimuth angle of departure (AAoD), elevation angle of departure (EAoD), azimuth angle of arrival (AAoA), and elevation angle of arrival (EAoA) based on the non-stationary nature of the channel model. In the model, we investigate the time-varying spatial cross-correlation functions (CCFs) and temporal auto-correlation functions (ACFs) with respect to the different moving directions and velocities of the UAV transmitter and ground receiver. Furthermore, we derive and study the Doppler power spectral densities (PSDs) and power delay profiles (PDPs) of the proposed channel model. Numerical results show that characteristics of the proposed channel model are very close to those of practical measurements, which provide a new and practical approach to evaluate the performance of next generation UAV-MIMO communication systems.
PERTURBATIVE APPROACH FOR FAST AND ACCURATE EVALUATION OF QUASI AXIALLY-SYMMETRIC CAVITY RESONANCE FREQUENCY IN DRIFT TUBE LINACS

In this paper, we present an analytical method, employable with commercial full-wave electromagnetic CADs, which allows full-wave simulations of large electromagnetic (EM) structures (i.e., in terms of wavelength), such as linear accelerator cavities (LINACs) and a very accurate estimation of their operating frequency. The proposed technique is based on the exploitation of rotational symmetry through the definition of equivalent axially-symmetric volumes which replace the non axially-symmetric ones inside the structure being analyzed. After a theoretical study, we show the successful application of the method in the real case study of a Drift Tube Linac (DTL) cell.

Evaluating The Implementation of The SWITCH® School Wellness Intervention Through Mixed Methods

Background: School wellness programming is important for promoting academic achievement and healthy lifestyles in youth; however, research is needed on methods that can help schools implement and sustain programs on their own. The purpose of this study was to investigate factors within and outside the school environment that impacted school capacity for implementation and potential sustainability of wellness programming. Methods: As part of the School Wellness Integration Targeting Child Health (SWITCH®) intervention, elementary school wellness teams (N=30) were guided through a capacity-building process focused on promoting the adoption of healthy lifestyle behaviors in students. Data on implementation were collected through three standardized surveys and interviews (pre-mid-post) and a post-implementation interview. Indicators of organizational capacity were assessed using the School Wellness Readiness Assessment (SWRA). Paired t-tests were run to assess changes in implementation (classroom, physical education, lunchroom settings), capacity, and stakeholder engagement over time. One-way analysis of variance (ANOVA) tests were run to examine how implementation of best practices (low, moderate, high) explained differences in capacity gains. Qualitative data were analyzed through inductive and deductive analysis, following the Consolidated Framework for Implementation Research (CFIR). Results: Paired t-tests showed non-significant increases in school and setting-specific capacity and implementation of SWITCH best practices over time, in addition to a consistent level of engagement from key stakeholders. ANOVA analyses revealed positive, non-significant variances between implementation group and gains in school capacity (F[2,24]=1.63; p=.21), class capacity (F[2,24]=0.20 p=.82), lunchroom capacity (F[2,24]=0.29; p=.78), and physical education (F[2,24]=1.45; p=.25). Qualitative data demonstrated factors within the outer setting (i.e., engaging community partners) that facilitated programming. Inner-setting factors (i.e., relationships with administration and staff) significantly affected implementation. Implementation process construct themes (e.g., planning, adaptation of resources to meet school capacity/needs, and engaging students as leaders) were cited as key facilitators. Schools discussed factors impacting sustainability, such school culture and knowledge of school wellness policy. Conclusions: Findings suggest a modest but important impact of implementation on capacity change which is the primary goal of SWITCH. The results document the importance of allowing schools to adapt programming to meet their local needs.
