Saline Irrigation Affects Growth and Leaf Tissue Nutrient Concentration of Three Native Landscape Plant Species
Authors: LeCompte Judson S. , Wright Amy N. , LeBleu Charlene M. , Kessler J. Raymond
Published: October 2019

Greywater is a renewable irrigation alternative to potable water; however, its use as an irrigation source is limited by the potential for salt injury to plants. Research was conducted to determine salt tolerance of three common landscape species, small anise tree (Illicium parviflorum), ‘Henry’s Garnet’ sweetspire (Itea virginica), and muhly grass (Muhlenbergia capillaris). Two experiments were performed, one with high sodium chloride (NaCl) concentrations and one with low NaCl concentrations. Plants received daily irrigation of tap water containing one of the following NaCl concentrations: 0 (tap water); 2000, 4000, 6000, 8000, or 10,000 mg·L−1 (high NaCl); or 0 (tap water), 250, 500, or 1000 mg·L−1 (low NaCl) for 15 weeks. Plants were harvested after 5, 10, or 15 weeks. Root dry weight (RDW) and shoot dry weight (SDW) were determined at each harvest; survival was determined at experiment termination. Leaf tissue was analyzed for tissue macronutrient [nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and, magnesium (Mg)], sodium (Na), and chlorine (Cl) concentrations in the high NaCl concentration experiment. With high NaCl, RDW and SDW decreased with increasing NaCl for all species. Anise and sweetspire had low or no survival, respectively, at the highest NaCl concentration; muhly grass had 100% survival regardless of treatment. In general, leaf macronutrient, Na, and Cl increased with increasing NaCl concentration. With low NaCl, there was no effect of NaCl concentration on RDW or SDW for all species. All three species continued to grow between harvest dates in the lower NaCl concentration experiment, whereas only anise and muhly grass continued to grow with high NaCl. Anise and muhly grass were tolerant of saline irrigation that could be expected from greywater. Sweetspire exhibited symptoms of salt stress (necrotic leaves and leaf drop, visual observation) at all NaCl concentrations including the lowest (250 mg·L−1), and should not be irrigated with saline water.

Authors: Braun Ross , Fry Jack , Kennelly Megan , Bremer Dale , Griffin Jason
Published: October 2019

Zoysiagrass (Zoysia sp.) is a warm-season turfgrass that requires less water and fewer cultural inputs than cool-season grasses, but its widespread use by homeowners in the transition zone may be limited because of its extended duration of brown color during dormancy. Turf colorants are an option for improving zoysiagrass winter color. Our objective was to quantify the impact of colorants applied in autumn at three application volumes on persistence of green color on lawn-height ‘Chisholm’ zoysiagrass (Zoysia japonica). The commercial colorants Green Lawnger, Endurant, and Wintergreen Plus were applied in Oct. 2013 in Manhattan, KS, and Haysville, KS, in solutions with water at 80, 160, or 240 gal/acre at a 1:6 dilution (colorant:water) and evaluated through late 2013 and Spring 2014. Tall fescue (Festuca arundinacea), a cool-season turfgrass commonly used in home lawns in the transition zone, was included for comparison. Persistence of green color increased with application volume, but differences among colorants were limited. Colorants provided acceptable color (i.e., a visual rating ≥6 on a 1 to 9 scale) for 55 to 69 days at 80 gal/acre, 69 to 118 days at 160 gal/acre, and 118 to 167 days at 240 gal/acre. Compared with tall fescue, colorant-treated zoysiagrass had significantly higher color ratings for 98 to 112 days at 80 gal/acre, 112 to 154 days at 160 gal/acre, and 138 to 154 days at 240 gal/acre. Colorants increased turfgrass canopy temperature by up to 12.1 °F, but did not accelerate spring green-up. Duration of acceptable color on ‘Chisholm’ zoysiagrass lawns can be enhanced by increasing colorant application volume.
Quantifying Growth Control of Lantana Cultivars Varying in Vigor with Ancymidol, Flurprimidol, Paclobutrazol, and Uniconazole Substrate Drenches
Authors: Currey Christopher J. , Walters Kellie J. , McCabe Kenneth G.
Published: October 2019

Our objective was to quantify the efficacy of different plant growth regulator (PGR) substrate drenches on growth of lantana (Lantana camara) cultivars varying in growth habit. Rooted ‘Little Lucky Peach Glow’, ‘Lucky Peach’, and ‘Landmark Peach Sunrise’ lantana cuttings were individually planted into 4-inch-diameter containers filled with a commercial, soilless growing substrate. Fourteen days after planting, solutions containing 0 (control), 0.5, 1, 2, or 4 mg·L−1 ancymidol, flurprimidol, paclobutrazol, or uniconazole were applied to the surface of the growing substrate. Six weeks after applying PGR drenches, data were collected. The growth index (GI), an integrated measurement of plant size incorporating the height and widths of plants, was calculated. There was variation in the GI among the control plants, reflecting variation among cultivars within the species. In addition, we measured variation in activity among the different PGRs applied. Across the concentrations applied, ancymidol generally had the lowest activity across the four PGRs. For example, drenches containing 4 mg·L−1 ancymidol resulted in plants that were similar to plants treated with 0.5 to 1 mg·L−1 flurprimidol or uniconazole or 2 mg·L−1 paclobutrazol for ‘Lucky Peach’ lantana. Across all cultivars, flurprimidol and uniconazole had the greatest activity in suppressing plant height, width, and GI. Substrate drenches containing flurprimidol, paclobutrazol, or uniconazole are useful to control size of lantana produced in containers, though the recommended concentration depends on the active ingredient and the growth habit of cultivars being treated.

Published: October 2019

A cohort of sixth grade students at two newly constructed elementary schools in Seoul, South Korea, performed a self-assessment of ocular discomfort symptoms in association with indoor air quality (IAQ) by indoor plant intervention from early June to mid-Oct. 2011. Indoor plant intervention made little difference in air temperature and relative humidity, but stabilized the increasing levels of carbon dioxide. The indoor concentrations of formaldehyde and ethylbenzene showed little difference, but those of toluene and xylene showed a decreasing trend in classrooms with indoor plants. The participants in classrooms without indoor plants exhibited an increase in ocular discomfort symptoms at School A and a decrease in symptoms at School B; those in classrooms with indoor plants demonstrated a decrease in frequency at both schools. The variation of symptom severity did not follow a clear trend. Participants assessed their symptom severity of ocular discomfort with four options from three points for frequent occurrence to zero points for no occurrence. Among participants in classrooms without indoor plants, symptom severity significantly worsened at both schools as the scores increased from 1.96 to 2.17 at School A and from 2.27 to 2.34 at School B; among those in classrooms with indoor plants, symptom severity significantly lessened at School A and slightly worsened at School B as the scores decreased from 2.33 to 1.98 at School A and increased from 2.35 to 2.42 at School B. After spending the experimental duration in classrooms without indoor plants at both schools, 34.8% of participants at School A and 33.3% of participants at School B perceived their symptom severity as having increased. At Schools A and B, indoor plants decreased the frequency of participants experiencing an increase of symptom severity by 13.0% and 9.7%, and increased the frequency of participants reporting decrease of symptom severity by 34.8% and 22.6%.
Scion Shoot Removal and Rootstock Cultivar Affect Vigor and Early Yield of Grafted Tomatoes Grown in High Tunnels in the Central United States

Published: October 2019

Grafting with interspecific hybrid rootstock is effective for tomato (Solanum lycopersicum) growers looking to reduce soilborne disease in the southeastern United States. However, production with grafted tomato has not been tested in the central United States, where soilborne disease pressure is low. Small-acreage growers would like to produce grafted plants themselves, but many have difficulty with propagation due to water stress in the scion postgrafting and/or high temperatures. Removing the upper portion of the scion to reduce leaf area during the grafting procedure [shoot removal (SR)] could help to reduce water stress postgrafting, but there are no data available that indicate what effect this practice has on tomato yield. Five high tunnel trials and one open-field trial were conducted in 2011 and 2012 to investigate potential yield effects related to the use of two rootstocks and SR during the grafting procedure. The implementation of grafting with rootstocks significantly increased fruit yield in five of the six trials (P < 0.05). The average yield increases by ‘Maxifort’ and ‘Trooper Lite’ tomato rootstocks were 53% and 51%, respectively, across all trials. SR during the grafting process may penalize tomato yield and our results suggest that rootstock vigor plays a role. Plants grafted with ‘Maxifort’ across all of the trials consistently increased shoot biomass in four of five of the high tunnel trials compared with nongrafted plants (P < 0.05), whereas plants grafted with ‘Trooper Lite’ rootstock increased shoot biomass in one trial. Similarly, the SR method penalized the total fruit yield of plants grafted with ‘Trooper Lite’ more often than those that were grafted with ‘Maxifort’. Our results suggest that plant growth and ultimately tomato fruit yield is affected negatively by using the SR grafting technique, particularly when less vigorous rootstock is used.
Cultivar, Growing Media, and Nutrient Source Influence Strawberry Yield in a Vertical, Hydroponic, High Tunnel System

Published: October 2019

Demand for local food, including strawberries (Fragaria ×ananassa), is increasing throughout the United States. Strawberry production in the midwestern United States can be challenging due to the relatively short growing season and pests. However, vertical, hydroponic, high tunnel production systems could extend the growing season, minimize pest incidence, and maximize strawberry yield and profitability. The objectives of this study were to 1) identify the best cultivars and growing media for vertical, hydroponic, high tunnel production of strawberries in the midwestern United States and to 2) assess potential strategies for replacing synthetic fertilizer with organic nutrient sources in hydroponic strawberry production. To accomplish these objectives, three experiments were conducted across 2 years and two locations in Illinois to compare 11 strawberry cultivars, three soilless media mixtures, and three nutrient sources. Strawberry yield was greatest when grown in perlite mixed with coco coir or vermiculite and fertilized with a synthetic nutrient source. Yield was reduced by up to 15% when fertilized with a bio-based, liquid nutrient source and vermicompost mixed with soilless media. Strawberry yield among cultivars varied by year and location, but Florida Radiance, Monterey, Evie 2, Portola, and Seascape were among the highest-yielding cultivars in at least one site-year. Results contribute to the development of best management practices for vertical, hydroponic, high tunnel strawberry production in the midwestern United States, but further research is needed to understand nutrient dynamics and crop physiological response among levels within vertical, hydroponic towers.
Effect of Different Commercial Substrates on Growth of Petunia Transplants
Authors: Li Yuqi , Mattson Neil S.
Published: October 2019

The objective of this study was to evaluate the growth and flowering of petunia (Petunia ×hybrida) transplants in response to seven commercial substrates with two water sources (fertigation and clear water irrigation). Seven commercial substrates used were Sunshine #1 Natural & Organic (SS), Metro-Mix 360 (MM), AgriTech (AT), Cornell Peat-Lite Mix B (CB), Jeff’s Organic (JO), LM-18, and LM-111. The experiment was a completely randomized 2 × 7 factorial design with six single-pot replications per treatment. With fertigation, substrate electrical conductivity (EC) decreased over time to 38 days after transplanting (DAT), and then did not further change. The AT substrate EC value was greater than others during the first 38 DAT. With clear water irrigation, substrate EC decreased over time to 31 DAT, and then did not further change. The AT substrate EC value was greater than other substrates during the entire petunia growth period. With fertigation, all substrate pH values were between 6.5 and 7.5 except AT and CB. The AT substrate had the greatest pH ranging from 7.5 to 8.0 during the petunia growth period. The CB substrate exhibited the lowest pH, which was between 5.8 and 6.3. Clear water irrigation had greater substrate pH values than fertigation. There was a substrate and water interaction for calcium (Ca), potassium (K), ammonium-nitrogen (NH4+-N), nitrate-nitrogen (NO3−-N), and sodium (Na) concentrations in substrate leachate. At 52 DAT, the shoot dry weight (DW), root index (RI), and flower number of petunia grown in AT substrate were greatest among all the substrates, but chlorophyll index (SPAD) was the lowest under either the fertigation or clear water irrigation treatments. The DW and RI of petunia grown in AT substrate were greater when fertigation was used than clear water irrigation, but the water source had no effect on flower number. For SS, MM, CB, JO, LM-18, and LM-111 substrates, fertigation increased petunia DW, RI, and flower number as compared with clear water irrigation, but not SPAD readings.
Stakeholder Opinions on Invasive Species and Their Management in the San Marcos River
Authors: Oxley Florence M. , Waliczek Tina M. , Williamson Paula S.
Published: October 2019

The San Marcos River in Texas supports a wide diversity of aquatic organisms and provides critical habitat for eight endangered species. It is also a highly invaded ecosystem, with 48 documented introduced species. Several of these are invasive and known to negatively impact native species. Increasing pressure to control or eradicate invasive species exists to mitigate their impacts. Management programs can be controversial and, in some cases, have been delayed or stopped because of public opposition. People who have a vested interest in an invaded ecosystem, stakeholders, may be the most likely to express opposition or offer support for invasive species control. Understanding opinions can help guide educational outreach to gain public support for management programs. To assess stakeholder’s opinions of invasive species (defined as species that cause harm to the environment or human health), a survey instrument was distributed, and 335 completed surveys were analyzed. The majority of survey participants believed nonnative, invasive species should be controlled to conserve the environment (84.4%), where they damage native Texas species (75.9%), and in particular when they threaten rare Texas native species (89%). Proposed management methods influenced levels of support for invasive species control. Significant differences among demographic groups were found in membership in environmental organizations, knowledge of invasive species in the river, and sources of information on invasive species.

Published: October 2019

Twelve commercial cauliflower (Brassica oleracea var. botrytis) varieties were evaluated for horticultural traits and susceptibility to alternaria leaf spot (Alternaria brassicicola) at the New York State Agricultural Experiment Station in Geneva, NY, in 2014 and 2015. Data including total yield, curd weight, curd width, plant height, days to maturity, and length of harvest were collected for each variety. A duplicate trial was planted in each year and inoculated with A. brassicicola, the causal agent of alternaria leaf spot, and the percentage of disease was assessed for each commercial cauliflower variety. Most of the commercial varieties were similar in susceptibility to disease and yield. ‘Artica’ and ‘Apex’ were ranked among the highest yielding varieties each year of the trial. The varieties ‘Graffiti’ and ‘Violet Queen’, both of which produce purple curds, had significantly less alternaria leaf spot compared with other varieties. Differences were seen between the 2 years of the trial in performance of individual varieties as influenced by temperatures during the growing season. This study demonstrates that some cauliflower varieties perform better than others under New York State growing conditions.
Structural Cohesion: Visualization and Heuristics for Fast Computation
Authors: Torrents Jordi , Ferraro Fabrizio
Published: October 2019

The structural cohesion model is a powerful theoretical conception of cohesion in social groups, but its diffusion in empirical literature has been hampered by operationalization and computational problems. In this paper, we start from the classic definition of structural cohesion as the minimum number of actors who need to be removed in a network in order to disconnect it, and extend it by using average node connectivity as a finer grained measure of cohesion. We present useful heuristics for computing structural cohesion that allow a speed-up of one order of magnitude over the algorithms currently available. We analyze three large collaboration networks (co-maintenance of Debian packages, co-authorship in Nuclear Theory and High-Energy Theory) and show how our approach can help researchers measure structural cohesion in relatively large networks. We also introduce a novel graphical representation of the structural cohesion analysis to quickly spot differences across networks.
Charged quantum fields in AdS$_2$
Authors: Anninos Dionysios , Hofman Diego , Kruthoff Jorrit
Published: October 2019

We consider quantum field theory near the horizon of an extreme Kerr
black hole. In this limit, the dynamics is well approximated by a tower
of electrically charged fields propagating in an
SL(2,\mathbb{R})SL(2,ℝ)
invariant AdS_22
geometry endowed with a constant, symmetry preserving background
electric field. At large charge the fields oscillate near the
AdS_22
boundary and no longer admit a standard Dirichlet treatment. From the
Kerr black hole perspective, this phenomenon is related to the presence
of an ergosphere. We discuss a definition for the quantum field theory
whereby we ‘UV’ complete AdS_22
by appending an asymptotically two dimensional Minkowski region. This
allows the construction of a novel observable for the flux-carrying
modes that resembles the standard flat space
SS-matrix.
We relate various features displayed by the highly charged particles to
the principal series representations of SL(2,\mathbb{R})SL(2,ℝ).
These representations are unitary and also appear for massive quantum
fields in dS_22.
Condiciones sociales de los pobladores en las zonas de conflicto minero en el Perú
Authors: Ramirez Julca Máximo
Published: October 2019

El objetivo de esta investigación fue describir y analizar las condiciones sociales de los pobladores en las regiones del Perú, donde se suscitan conflictos sobre la explotación minera. Los resultados demuestran el desconocimiento de los pobladores en relación a las normas legales, de los pueblos que conforman las zonas mineras.El Perú, es uno de los países más importantes de Latinoamérica en cuanto a la minería, empero encuentra sumergido en conflictos sociales muy sensibles, hasta el extremo de ponerse en riesgo en cuanto a su desarrollo económico. Las conclusiones indican que las políticas de estado, no han sido aplicadas adecuadamente como mecanismos de diálogo al apego de las normas constitucionales, se han dejado marginadas las políticas institucionales, que pudieron haber servido para el aprovechamiento de los recursos naturales con desarrollo sustentable, asumiendo con responsabilidad los derechos de los pueblos.En los lugares donde existen conflictos relacionados a la minería, los ambientes sociales están polarizados, manipulados con mucha habilidad por los agitadores ideológicos, quienes buscan desestabilizar todo esfuerzo de tolerancia entre los responsables autoridades y los pobladores. Las evidencias muestran ausencia de dialogo entre los pobladores, autoridades locales y el gobierno central, ausencia absoluta de los colegios profesionales de ingenieros, de abogados, de médicos entre otros. Finalmente, es necesario analizar la Carta Magna del Perú, que precisa la propiedad estatal del subsuelo, que señala en su artículo 66º dice literalmente “Los recursos naturales, renovables y no renovables, íntegramente pertenecen al patrimonio de la nación.
YÛSUF HÂLİS’İN “VATAN KASİDESİ”NDE DİVAN EDEBİYATINA YÖNELİK ELEŞTİRİLER
Authors: OKTAY Metin
Published: October 2019

İlk örnekleri XIII. yüzyılda görülmeye başlayan divan edebiyatı altı yüzyıllık bir hayatiyetten sonra XIX. yüzyıldan itibaren çözülerek ömrünü tamamlamıştır. Tanzimat’ın ilanından sonra Osmanlı Devleti’nin yönünü Batıya çevirmesiyle dönemin yenilikçi aydınları tarafından divan edebiyatı ağır eleştirilere maruz kalmıştır. Kuralcı yapısı, tutucu geleneği, dilinin ağırlığı, hakikate ilgisizliği, toplumsal meselelere kayıtsızlığı, duygu, düşünce ve hayal dünyasının kapalılığı iddiaları bu eleştirilerin merkezini oluşturur. Edebiyat çevreleri divan edebiyatına yöneltilen bu itirazların ilk olarak Namık Kemal’in 1866 yılında Tasvîr-i Efkâr gazetesinde yayımlanan “Lisân-ı Osmânî’nin Edebiyatı Hakkında Bazı Mülâhazâtı Şâmildir” adlı makalesiyle başladığını ifade ederler. Bununla birlikte Türk edebiyatının ihmal edilmiş şairlerinden Yûsuf Hâlis tarafından 1854’de yazılan “Şeh-nâme- i Osmânî” adlı eserde yer alan 102 beyitlik “Vatan Kasidesi”nin 48-71. beyitleri arası toplam 25 beyitte divan edebiyatına karşı ağır tenkitler/ithamlar bulunmaktadır. Başka bir deyişle Yûsuf Hâlis, Namık Kemal’den yaklaşık olarak 22 yıl önce divan edebiyatını sert bir dille eleştirmiştir. Ona göre eski edebiyat şairleri kaside ve gazellerini menfaatleri için yazmışlardır; şiirlerinde sürekli sevgiliyi, parayı, üst tabakayı dikkate almışlardır; methettikleri şahsiyetleri şiirlerinde göklere dek çıkarmışlardır; hep mecazi aşk vadisinde dolaşmışlar; divanlarını sümbül, gül, sevgili ve şarapla doldurmuşlardır; tuhaf sözlerle şiirlerini gösterişe boğmuşlardır; Türkçeyi Arapça ve Farsça kelimelerle doldurmuşlardır. Yûsuf Hâlis bu eleştirilerinin ardından “Vatan Kasidesi”nde ideal bir şairde ve şiirde bulunması gereken özelliklere değinmektedir. Ona göre şairler, şiirlerinde “vatan” gibi kutsal bir konuya da yer vermelidir. Vatan temalı şiirleri okuyan çocukların karakteri olumlu yönde şekillenir. Şiirlerin terbiye edici özelliği olmalıdır. Devlete ve millete katkı sağlamalıdır. Taş kalplilerinin vicdanına bile tesir etmelidir. Vatanda yaşayan hem bilgisize hem de âlime seslenmelidir. Kötü işleri ayıplamalı, iyi işleri övmelidir. Hz. İsa gibi cansız bedenlere hayat vermeli, şiirleriyle Hz. Musa’nın ejdere dönüşen asası gibi okuyanı hareketlendirmelidir.Bu çalışmada Yûsuf Hâlis’in “Vatan Kasidesi”nde divan şiirine ve divan şairlerine yönelik görüş, düşünce ve eleştirilerinin bulunduğu beyitler yer yer Namık Kemal’in “Lisân-ı Osmânî’nin Edebiyatı Hakkında Bazı Mülâhazâtı Şâmildir” adlı makalesine atıflar yapılarak irdelenmeye çalışılacaktır.

Introducción: En el centro de México, el frijol tipo Flor de Junio (FJ) es de alta demanda; se produce bajo condiciones de riego y temporal en Zacatecas, San Luís Potosí y Guanajuato. Por lo general el grano de las variedades del tipo FJ muestra oscurecimiento en el almacén. El objetivo fue identificar líneas de frijol tipo FJ, seleccionadas previamente por oscurecimiento, de alto rendimiento y peso del grano estables bajo condiciones de temporal.Método: Se estableció en Celaya, Gto., un experimento bajo condiciones de temporal con 42 líneas F7 provenientes de la cruza biparental entre Pinto Saltillo / Dalia en Calera, Zac. y Celaya, Gto.Los progenitores se establecieron en unensayo separado dentro de la misma localidad. Las variables evaluadas fueron peso de cien semillas y rendimiento por hectárea. Se realizó un análisis combinado que consideró los efectos de localidades, líneas e interacción genotipo x ambiente (IGA). Para determinar el nivel de IGA de cada línea se utilizó el modelo AMMI. Las cinco líneas con rendimiento superior fueron expuestas por 72 h a rayos UV para su oscurecimiento acelerado y se determinó cuantitativamente la intensidad del color y grado de claridad de la testa junto con el testigo de oscurecimiento lento, Pinto Saltillo. Resultados y Discusión: Para ambas variables evaluadas hubo diferencias significativas entre ambientes, genotipos e interacción (P ≤ 0.05). Algunas líneas presentaron mayor peso y rendimiento que el promedio, y comparadas con los progenitores establecidos en Celaya, lo que se puede atribuir a genes complementarios con acción génica aditiva, además de observarse segregación transgresiva, tanto positiva como negativa. Las líneas de mayor rendimiento, de 2.203 a 2.334 kg. ha-1 fueron PS/D-M-M-26-1-M, PS/D-M-M-38-1-M, PS/D-M-M-17-1-M, PS/D-M-M-42-1-M y PS/D-M-M-39-1-M. El análisis AMMI para peso de cien semillas indicó que 47.27 % de la variación la explicó el ambiente, 38.66 los genotipos y la interacción el 14.07 %. Para el rendimiento 13.79 % de la variación fue explicada por el ambiente, 40.77 % por el genotipo y 45.44 por la interacción. La línea PS/D-M-M-38-1-M mostro baja IGA, por lo cual se considera estable. Las líneas al inicio del tratamiento con UV fueron ligeramente más oscuras que Pinto Saltillo, sin embargo, durante el proceso el incremento gradual fue menor que el del testigo.Conclusiones: En promedio, en ambas localidades de prueba, se identificaron líneas de alto rendimiento, superiores al promedio de las líneas. Las líneas de mayor rendimiento también presentaron la característica de oscurecimiento lento. La línea PS/D-M-M-38-1-M, de baja IGA, resultó sobresaliente en todas las características evaluadas.

Published: October 2019

Rabbit meat usage in processed products is low. However, rabbit meat raw sausage can be an alternative to increase this meat’s market share. The objective of this study was to determine the effect of blending textured soybean protein and rabbit meat on the texture profile analysis and sensory properties of the chorizo. Five treatments were designed, one control and another four using blends of rabbit meat and textured soybean in ratios of 10, 20, 30 and 40%. Measurements were water activity, texture profile analysis, and color, while a sensory test was conducted at the end of experiments for four treatments. The main results indicate that Aw and pH values decreased (p< 0.05), while b* value increased with storage time (p<0.05). L* value decreased after 7 d vacuum packing, but then increased after 14 d. Treatment with 20% of textured soybean results in less hardness and more springiness. Sensory analysis indicates that there is not significant difference in odor global appearance in all treatments (p>0.05), but color, hardness and taste were different (p<0.05). In conclusion, textured soybean protein can be blended with rabbit meat for processing chorizo. The meat product obtained has sensorial characteristics, a texture profile, Aw and color acceptable for this kind of raw sausage, especially in blends with 20 and 30% of textured soybean protein. Moreover, the blend of these two meat ingredients improved nutritional properties and could therefore be offering as a functional meat product.
Investigation into untreated greywater reuse practices by suburban households under the threat of intermittent water supply
Authors: Nel N. , Jacobs H. E.
Published: October 2019

Untreated greywater reuse at the household level is an accessible water source to supplement non-potable water requirements in times of emergency water curtailments but poses various risks to the consumer, the wider community, infrastructure and the environment. Little information is known about unregulated, untreated greywater reuse practices under emergency conditions in suburban communities where consumers have become accustomed to reliable potable water supplied via a pressurised, piped distribution system. There is a lack of knowledge regarding the sources of greywater used, collection methods, storage and distribution of greywater, the application points, the level of treatment (if any) and the perceived risks associated with the greywater reuse. The City of Cape Town was selected as a case study site for research into greywater reuse under the threat of ‘Day Zero’ and stringent water restrictions, implemented during the 2017/2018 summer season. A consumer survey and analysis of relevant online forums was conducted in order to obtain the necessary information. Greywater reuse practices from a sample group of 351 consumers were identified and classified. Untreated greywater reuse was found to be common, mainly for garden irrigation and toilet flushing. The results point to high-risk activities in the study group.

Aspectos sociocognitivos do fracasso escolar
Authors: Voss Rita Ribeiro
Published: October 2019

As estatísticas governamentais sobre o ensino básico correlacionam origem social e fraco desempenho escolar. Quatro concepções marcam as pesquisas sobre o tema, que são insuficientes para compreendê-lo em sua complexidade: “concepção social”, “concepção psicológica”, “concepção microestrutural” e “concepção pedagógica”. Numa perspectiva interdisciplinar, os bens simbólicos medeiam processos cognitivos e meio social. Mas a sociedade transforma esse acesso em habilidade de se fazer abstrações. Para as crianças das classes populares, esse processo se dá, sobretudo, na escola, que obstrui o fluxo livre desses bens, tornando-se o lócus de “sonegação de saberes” e principal promotora de desigualdades sociais no Brasil.

Published: October 2019

Aims & Objective:

In this work, pyran derivatives were synthesized via a multicomponent reaction of ninhydrin, α-haloketones, dialkyl acetylenedicarboxylate, and triphenylphosphine in the presence of iron oxide magnetic nanoparticles (Fe3O4-MNPs) as efficient nanocatalyst in ethanol at room temperature.

Materials & Methods:

The biosynthesis of Fe3O4-MNPs was performed by Clover Leaf water extract. In addition, antioxidant activity was examined for the prepared compounds employing DPPH radical scavenging and ferric reduction activity potential (FRAP) experiment and comparing results with synthetic antioxidants (TBHQ and BHT).

Results:

Compound 5b showed excellent radical trapping activity and good reducing activity relative to standards (BHT and TBHQ).

Conclusion:

Some advantages of this procedure are: the workup of reaction is easy and the products can be separated easily by filtration. Fe3O4-MNPs display a good improvement in the yield of the product and showed significant reusable activity.

Published: October 2019

Blood coagulation is the process of changing the blood from the flowing state to the gel
state. It is an important part of the hemostatic function. Coagulation is a process by which a series of
coagulation factors are sequentially activated, and finally thrombin is formed to form fibrin clot. Direct
thrombin inhibitors are important anticoagulant drug. These drugs can selectively bind to the active
site of thrombin, inhibit thrombin activity, have strong action and high specificity, and have important
significance in the clinical treatment of thrombus diseases. Some of them come from natural products of
animals or plants, and many of them have been applied in the clinic. The other part is derived from the
design, synthesis and activity studies of small molecule inhibitors. This review discusses the progress of
direct thrombin inhibitors in recent years.
Relaxin and the Cardiovascular System: from Basic Science to Clinical Practice
Authors: Martins Rafael Clara , Pintalhão Mariana , Leite-Moreira Adelino , Castro-Chaves Paulo
Published: October 2019

The peptide hormone relaxin was originally linked to reproductive physiology, where it is believed to mediate systemic and renal hemodynamic adjustments to pregnancy. Recently, its broad range of effects in the cardiovascular system has been the focus of intensive research regarding its implications under pathological conditions and potential therapeutic potential. An understanding of the multitude of cardioprotective actions prompted the study of serelaxin, recombinant human relaxin-2, for the treatment of acute heart failure. Despite early promising results from phase II studies, recently revealed RELAX-AHF-2 outcomes were rather disappointing and the treatment for acute heart failure remains an unmet medical need. This article reviews the physiologic actions of relaxin on the cardiovascular system and its relevance in the pathophysiology of cardiovascular disease. We summarize the most updated clinical data and discuss future directions of serelaxin for the treatment of acute heart failure. This should encourage additional work to determine how can relaxin's beneficial effects be exploited for the treatment of cardiovascular disease.

Authors: Maitre Thomas , Muret Patrice , Blot Mathieu , Waldner Anne , Duong Michel , SI-Mohammed Ali , Chavanet Pascal , Aho Serge , Piroth Lionel
Published: October 2019

Background:

HIV infection is a chronic disease for which therapeutic adherence and tolerance
require particular attention.

Objective:

This study aimed to assess whether and when therapeutic drug monitoring (TDM) could
be associated with a benefit in routine practice.

Methods:

All HIV-infected patients who underwent at least one TDM at the University Hospital of
Dijon (France) between 1st January 2009 and 31st December 2012 were retrospectively included.
Compliance with the recommendations, the results (antiretroviral concentrations), any subsequent
therapeutic modifications, and the virological results at 4-8 months were analysed each time TDM
was performed. TDM was defined as “practically relevant” when low or high antiretroviral concentrations
led to a change in therapy.

Results:

Of the 571 patients who followed-up, 43.4% underwent TDM. TDM complying with recommendations
(120 patients) was associated with a higher proportion of antiretroviral concentrations
outside the therapeutic range (p=0.03). Antiretroviral treatment was modified after TDM in
22.6% of patients. Protease inhibitors, non-nucleoside reverse transcriptase inhibitors and raltegravir
were more significantly modified when the measured concentration was outside the therapeutic
range (p=0.008, p=0.05 and p=0.02, respectively). Overall, 11.7% of TDM was considered “practically
relevant”, though there was no significant correlation between subsequent changes in antiretroviral
treatment and undetectable final HIV viral load.

Conclusions:

TDM may be a useful tool in the management of HIV infection in specific situations,
but the overall benefit seems moderate in routine practice. TDM cannot be systematic and/or a decision
tool per se, but should be included in a comprehensive approach in certain clinical situations.

Authors: Domínguez María Dolores Lara , González Carlota García-Salmones , Bermejo Elena Mantrana , Fernández Virginia Caballero , López María Rosa Oña
Published: October 2019

Background::

A retrospective study that analysed data for three consecutive years from the Hysteroscopy Clinic at the Department of Obstetrics and Gynecology, Valme University Hospital.

Objective::

To analyse the data of lesions removed in the hysteroscopy clinic in comparison with those scheduled for the operating room to show that hysteroscopy could be a more effective procedure.

Method::

Patients undergoing operative hysteroscopy for various indications were included. The 5 mm Bettocchi hysteroscopes and the 5.8 mm Palex Mini-Resectoscope were used.

Results::

A total of 1233 patients were seen in the hysteroscopy clinic between 2015 and 2017. In 2015, 344 hysteroscopies were performed, of which 57 (16.5%) were performed in the operating room. In 2016, 445 hysteroscopies were performed and 46 (10.3%) were scheduled in the operating room. During 2017, a total of 444 hysteroscopies were performed, of which only 6 (1.3%) were performed in the operating room (P < 0.001). Five large fibroids and one case of complex polyp were removed in the operating room in 2017. The mini-resector was used in 202 cases (45.4%). Paracervical local anaesthesia was given to 383 (86.2%) patients.

Conclusion::

The data obtained in our study shows a significant reduction in the number of hysteroscopies scheduled for surgery in 2017 (1.3%) and, therefore, hysteroscopy has been shown to be a more effective procedure. This trend may be due to the introduction of the mini-resectoscope and the use of paracervical local anaesthesia.

Authors: S. Sumathi , V. Agalya
Published: October 2019

Introduction:

A progressive and flourishing technological advancement occurs across
the communities working on a domain that needs clinical training and Technology Transfer. There
is an essentiality for the evolution of advanced concepts in the Classification of healthcare, particularly
in relation to arrhythmia detection towards clinical operations. Being the forerunner among
the emerging areas in science and technology, this field demands an extensive practical and verification
research. These innovative technological progress has significantly contributed to highquality,
on-time, acceptable and affordable healthcare.

Materials and Methods:

This paper approaches a novel method of Detecting and classifying the cardiac
arrhythmias using deep learning model for classification of electrocardiogram (ECG) signals.
This method is based on using Cubic Wavelet Transform for analyzing the ECG signals and extracting
the parameters related to dangerous cardiac arrhythmias.

Results and Discussion:

In these parameters are used as input to these classifier, five most important
types of ECG signals they are Normal Sinus Rhythm (NSR), Atrial Fibrillation (AF), Pre-
Ventricular Contraction (PVC), Ventricular Fibrillation (VF), and Ventricular Flutter (VFLU). By
using the deep learning algorithm to recognition and classification capabilities across a broad area
of biomedical engineering. The performance of the deep learning model was evaluated in terms of
training performance and classification accuracies. The classification accuracy of 99.24% is
achieved. Good accuracy of ECG patterns is achievable only over a large number of files.

Conclusion:

These difficulties have necessitated us to develop a new detection scheme, which
gives a high level of accuracy, low false positive and low false-negative statistics.
AdipoRon: A Novel Insulin Sensitizer in Various Complications and the Underlying Mechanisms: A Review
Authors: Bhat Ishfaq Ahmad , Kabeer Shaheen Wasil , Reza Mohammad Irshad , Mir Reyaz Hassan , Dar Muhammad Ovais
Published: October 2019

Background:

AdipoRon is the first synthetic analog of endogenous adiponectin, an adipose tissue-derived hormone. AdipoRon possesses pharmacological properties similar to adiponectin and its ability to bind and activate the adipoR1 and adipoR2 receptors makes it a suitable candidate for the treatment of a multitude of disorders.

Objective:

In the present review, an attempt was made to compile and discuss the efficacy of adipoRon against various disorders.

Results:

AdipoRon is a drug that acts not only in metabolic diseases but in other conditions unrelated to energy metabolism. It is well- reported that adipoRon exhibits strong anti-obesity, anti-diabetic, anticancer, anti-depressant, anti-ischemic, anti-hypertrophic properties and also improves conditions like post-traumatic stress disorder, anxiety, and systemic sclerosis.

Conclusion:

A lot is known about its effects in experimental systems, but the translation of this knowledge to the clinic requires studies which, for many of the potential target conditions, have yet to be carried out. The beneficial effects of AdipoRon in novel clinical conditions will suggest an underlying pathophysiological role of adiponectin and its receptors in previously unsuspected settings.
A Review on Different Biometric Template Protection Methods
Authors: Sarkar Arpita , Singh Binod K.
Published: October 2019

Biometrics is a universally used automatic identification of persons, depending on their
behavioral and biological quality. Biometric authentication represents a significant role in the identity
management system. Protection of biometric authentication systems demands to be discussed as
there are still some points related to the integrity and public receiving of biometric systems. Feature
extraction module of biometric authentication systems, during the period of enrolment, scan the biometric
information to determine a set of distinctive features. This set of totally distinct features is
recognized as a biometric template. This biometric template is effective in distinguishing between
different users. These templates are normally stored during the time of enrolment in a database arranged
by the user’s identification data. For the templates of biometrics, protection from attackers is
an essential issue, since the compromised template will not be canceled and reissued like a password
or token. Template security is not an obvious task because of variations present within the extracted
biometric features of users. This paper surveys about different existing approaches for designing
a protection scheme for biometric templates with their strengths and boundaries existing in
the literature. Some prospect information in designing template protection schemes have been elaborately
explained in this paper.
