Capacidad de propagación y calidad de planta de variedades mexicanas y extranjeras de fresa

This work was carried out in order to compare propagation capacity and quality of Mexican strawberry varieties (CP-Jacona and CPZamorana) and foreign commercial varieties (Festival and Albion). The four varieties were established in two nurseries located in Michoacan, Mexico at different altitudes: Tanaquillo (1,700 m) and Zirahuen (2,228 m). Eight mother plants and eight daughter plants were sampled as replications. Number of crowns, number of runners and daughter plants per mother plant were the variables studied. Root starch content and fresh and dry plant weight were recorded of the daughter plants. The statistical analysis was performed using the student’s t-test with 5 % significance level. The Mexican variety ‘Festival’ produced more runners, crowns and daughter plants in the nursery of Zirahuen, compared to other varieties; however, the starch content was higher in the Mexican varieties. In the nursery of Tanaquillo, both the ‘Festival’ and ‘CP-Jacona’ varieties showed higher number of daughter plants; however, the starch content in the ‘Festival’ variety was higher than in the ‘CP-Jacona’ variety. In the nursery of Zirahuen, the starch content of daughter plants was higher than in the nursery of Tanaquillo, but the number of daughter plants produced was notably higher at the nursery of Tanaquillo. At the nursery of Zirahuen, the ‘CP-Jacona’ variety had a lower capacity of runners and daughter plants production but these plants showed greater starch content but dry weight of daughter plants was similar to the USA varieties. At the nursery of Tanaquillo, the Mexican varieties were better in the production of daughter plants than the ‘Albion’ variety ADDITIONAL KEYWORDS: Fragaria x ananassa, plant propagation, reserves, dry matter accumulation, new varieties.
Tectonic setting of the Taltson magmatic zone at 1.92.0 Ga: a granitoid-based perspective

The Paleoproterozoic Taltson magmatic zone is one of the key tectonic features of western Laurentia. The existing tectonic model for the belt envisions its formation by subduction of oceanic crust beneath a continental margin, followed by direct collision between formerly separate crustal blocks. We tested this model by comparing the large geochemical and isotopic database available for Taltson magmatic zone granitoids with similar databases for Phanerozoic granitoid suites from different tectonic environments. The comparison reveals that the early granitoid suite of the Taltson magmatic zone, which had been ascribed to the subduction phase of orogenesis, lacks the mantle signature apparent in granitoids of Phanerozoic continental-margin arc settings. Instead, both early and late suites appear to have an intracrustal origin, similar to Mesozoic and Cenozoic granitoids of the Cordilleran interior of western North America, which formed in the distant hinterland of a convergent plate margin. In light of thes.
Modeling the density variation in the shallow firn layer

Abstract Vapor-transfer theory is incorporated into a previous firn-densification model to investigate the effect of vapor-transfer processes on densification in firn within 10 m of the surface. The densification rate in the model is governed by the change of overburden pressure (determined by the accumulation rate), the firn temperature, and the temperature gradient. The time of exposure to temperature gradients at shallow depths is a critical factor determining the importance of vapor-transfer processes. In high-accumulation and high-temperature conditions such as for the Greenland ice sheet, the temperature gradient and vapor transfer are less important due to the shorter exposure times. The high summer temperatures dominate the rate of densification and annual variations in density. In low-accumulation and low-temperature conditions, such as for inland Antarctica, the vapor transfer driven by the temperature gradient has a stronger effect on the densification rate, and temperature-driven processes are less important. These factors determine both the rate of density increase with depth and the amplitudes of annual variations in density with depth.
Contractile responses to endothelin-1 are regulated by PKC phosphorylation of cardiac myosin binding protein-C in rat ventricular myocytes

The shortening of sarcomeres that co-ordinates the pump function of the heart is stimulated by electrically-mediated increases in [Ca2+]. This process of excitation contraction coupling (ECC) is subject to modulation by neurohormonal mediators that tune the output of the heart to meet the needs of the organism. Endothelin 1 (ET-1) is a potent modulator of cardiac function with effects on contraction amplitude, chronotropy and automaticity. The actions of ET-1 are evident during normal adaptive physiological responses and increased under pathophysiological conditions, such as following myocardial infarction and during heart failure, where ET-1 levels are elevated. In myocytes, ET-1 acts through ETAor ETB-G protein-coupled receptors (GPCRs). Although well studied in atrial myocytes, the influence and mechanisms of action of ET-1 upon ECC in ventricular myocytes are not fully resolved. We show in rat ventricular myocytes that ET 1 elicits a biphasic effect on fractional shortening (initial transient negative and sustained positive inotropy) and increases the peak amplitude of systolic Ca2+ transients in adult rat ventricular myocytes. The negative inotropic phase was ETB receptor dependent, whereas the positive inotropic response and increase in peak amplitude of systolic Ca2+ transients required ETA receptor engagement. Both effects of ET 1 required phospholipase C (PLC)activity, although distinct signalling pathways downstream of PLC elicited the effects of each ET receptor. The negative inotropic response involved inositol 1,4,5-trisphosphate (InsP3) signalling and protein kinase C epsilon (PKCε). The positive inotropic action and the enhancement in Ca2+ transient amplitude induced by ET-1 were independent of InsP3 signalling, but suppressed by PKCε. Serine 302 in cardiac myosin binding protein-C was identified as a PKCε substrate that when phosphorylated contributed to the suppression of contraction and Ca2+ transients by PKCε following ET-1 stimulation. Thus, our data provide a new role and mechanism of action for InsP3 and PKCε in mediating the negative inotropic response and in restraining the positive inotropy and enhancement in Ca2+ transients following ET-1 stimulation.
Absence of (cid:1) v (cid:2) 6 Integrin Is Linked to Initiation and Progression of Periodontal Disease

Integrin (cid:1) v (cid:2) 6 is generally not expressed in adult ep-ithelia but is induced in wound healing, cancer, and certain fibrotic disorders. Despite this generalized absence, we observed that (cid:1) v (cid:2) 6 integrin is constitutively expressed in the healthy junctional epithelium linking the gingiva to tooth enamel. Moreover, expression of (cid:1) v (cid:2) 6 integrin was down-regulated in human periodontal disease, a common medical condi-tion causing tooth loss and also contributing to the development of cardiovascular diseases by increasing the total systemic inflammatory burden. Remarkably, integrin (cid:2) 6 knockout mice developed classic signs of spontaneous, chronic periodontal disease with char-acteristic inflammation, epithelial down-growth, pocket formation, and bone loss around the teeth. Integrin (cid:1) v (cid:2) 6 acts as a major activator of transforming growth factor- (cid:2) 1 (TGF- (cid:2) 1), a key anti-inflamma-tory regulator in the immune system. Co-expression of TGF- (cid:2) 1 and (cid:1) v (cid:2) 6 integrin was observed in the
Face Readers: The Frontier of Computer Vision and Math Learning

The future of AI-assisted individualized learning includes computer vision to inform intelligent tutors and teachers about student affect, motivation and performance. Facial expression recognition is essential in recognizing subtle differences when students ask for hints or fail to solve problems. Facial features and classification labels enable intelligent tutors to predict students’ performance and recommend activities. Videos can capture students’ faces and model their effort and progress; machine learning classifiers can support intelligent tutors to provide interventions. One goal of this research is to support deep dives by teachers to identify students’ individual needs through facial expression and to provide immediate feedback. Another goal is to develop data-directed education to gauge students’ pre-existing knowledge and analyze real-time data that will engage both teachers and students in more individualized and precision teaching and learning. This paper identifies three phases in the process of recognizing and predicting student progress based on analyzing facial features: Phase I: Collecting datasets and identifying salient labels for facial features and student attention/engagement; Phase II: Building and training deep learning models of facial features; and Phase III: Predicting student problem-solving outcome.
Stability of a chemically layered mantle

A system composed of two immiscible fluid layers and heated from below is analyzed to determine its stability to convective motions. The model is applicable to the mantle if some fraction of the density increase with depth results from changes in chemical composition. For different parameter ranges, three modes of instability are possible: (1) convection of the entire depth of the fluid, (2) separate convection within each layer, and (3) overstability in the form of standing waves on the interface between layers. Earth models that include an increase in density due to iron enrichment below 650 km suggest that mantle convection can exist above and below but not through the 650-km level. The model results are combined with a prior understanding of mineralogical phase changes to suggest a possible mechanism for the deepest earthquakes.
Effects of Ponderosa Pine Treatments on Water Yield in Arizona

Annual water yields were determined for three levels of overstory removal and three levels of strip cut with thinning applied on ponderosa pine watersheds. Water yield increases from a completely cleared watershed were statistically significant for 7 years, losing significance after recovery and growth of Gambel oak and herbaceous vegetation. Water yield increases were maintained 6 years after a light overstory removal and 10 years following a heavy overstory removal cut. Significant increases were obtained for 3–4 years following two levels of strip cut with thinning, but were then lost on watersheds with a high percentage of southern exposure or low slopes. Water yield increase remained at a 15% level during the first 6 years on a strip-cut watershed with 60% of its area on northern aspects.
For Peer

similar long-term extrapolations to externally validated SPMs based on later data-cuts. B-MPES generated reasonable predictions even when fitted to the 2-year DBLs of the studies, whereas MCMs were more reliant on longer-term data to estimate a plateau, and therefore performed better from 3 years. Generally, LRM extrapolations were less reliable than those from alternative FPMs and validated SPMs but remained superior to non-validated SPMs. Our work demonstrates the potential benefits of employing advanced parametric models that formally incorporate external data sources, such as B-MPES and MCMs, to allow for accurate evaluation of treatment clinical-and cost-effectiveness from limited trial data.

Tracking the Vector of Onchocerca lupi in a Rural Area of Greece

During a hot Mediterranean summer, an expedition brought parasitologists from Brazil, France, Greece, Italy, and Serbia to a wooded area near Xanthi, Thrace, northeastern Greece, near the Turkish border, on the track of the vector of the little-known nematode Onchocerca lupi. The scientific purposes of the expedition blended then with stories of humans, animals, and parasites in this rural area.
Intracrystalline Swelling of Mixed-Layer Illite-Smectite in K-Bentonites

Abstract To investigate the long-term stability of bentonite under final disposal conditions of highly radioactive waste, K-bentonites from Kinnekulle (Sweden) and from the Marias River Formation in the Montana disturbed belt (USA) were studied. After separating the mixed-layer illite-smectite (I-S) from the K-bentonite samples, the interlayer charge was calculated from the cation exchange capacity (CEC) and the amount of fixed interlayer K+ ions (Kfix). The interlayer charge was also determined by the alkylammonium method. According to both methods the interlayer charge was in the range for smectite. The results show that the amount of exchangeable cations increased linearly with decreasing Kfix. A small increase in the interlayer charge with increasing Kfix was observed as was a linear correlation between the intracrystalline swelling up to the second water layer, the CEC and the content of Kfix. Divalent exchangeable cations were then found to be surrounded by approximately 24 water molecules per cation. Fixed interlayer K+ ions were unhydrated. Forming the third and fourth water layer, swelling was presumably limited by free silica formed by the vitrification of the volcanic ash.
Ice-Sheet Flow Properties Derived from Bore-Hole Shear Measurements Combined With Ice-Core Studies

Abstract A 345 m deep bore hole in ice about 385 m thick, near the edge of Law Dome, Antarctica, was drilled in 1974 about 3 km up-stream from the site of a previous bore hole, nearly reaching the bed, obtained in 1969. The core from this new bore hole has been studied comprehensively, particularly with regard to the ice-crystal orientation fabrics. Samples of the ice core were subjected to simple shear at temperatures and deviatoric stresses which match the in situ conditions of the ice sheet. Similar studies of randomly-oriented laboratory-made polycrystalline ice were undertaken. Long-term tests, lasting for up to two years, were required to determine minimum strain-rates. The flow law for the anisotropic ice was thus determined as a function of that for the isotropic ice together with a measure of c-axis fabric strength perpendicular to the shear plane. Core studies indicate that the upper part of the ice sheet has a polycrystalline structure appropriate to the surface longitudinal stress. Deeper in the core a strong concentration of near-vertical c-axes develops. Ice having very large crystals with multiple maxima fabrics was found in the lower quarter of the ice thickness. Shear measurements in the bore hole indicate the existence of high strain-rates in the zone of vertical c-axes, and of lower shear-rates below that level. The low values of shear-rates in the basal region cannot be explained in terms of crystallographic changes alone, and therefore it is inferred that the shear stress decreases in this layer–a result which also provides a possible explanation for the development of the observed basal crystal structure.
Molecular subtype-speci ﬁ c ef ﬁ cacy of anti-EGFR therapy in colorectal cancer is dependent on the chemotherapy backbone

BACKGROUND: Patient selection for addition of anti-EGFR therapy to chemotherapy for patients with RAS and BRAF wildtype metastatic colorectal cancer can still be optimised. Here we investigate the effect of anti-EGFR therapy on survival in different consensus molecular subtypes (CMSs) and strati ﬁ ed by primary tumour location. METHODS: Retrospective analyses, using the immunohistochemistry-based CMS classi ﬁ er, were performed in the COIN ( ﬁ rst-line oxaliplatin backbone with or without cetuximab) and PICCOLO trial (second-line irinotecan with or without panitumumab). Tumour tissue was available for 323 patients (20%) and 349 (41%), respectively. RESULTS: When using an irinotecan backbone, anti-EGFR therapy is effective in both CMS2/3 and CMS4 in left-sided primary tumours (progression-free survival (PFS): HR 0.44, 95% CI 0.26 – 0.75, P = 0.003 and HR 0.12, 95% CI 0.04 – 0.36, P < 0.001, respectively) and in CMS4 right-sided tumours (PFS HR 0.17, 95% CI 0.04 – 0.71, P = 0.02). Ef ﬁ cacy using an oxaliplatin backbone was restricted to left-sided CMS2/3 tumours (HR 0.57, 95% CI 0.36 – 0.96, P = 0.034). CONCLUSIONS: The subtype-speci ﬁ c ef ﬁ cacy of anti-EGFR therapy is dependent on the chemotherapy backbone. This may provide the possibility of subtype-speci ﬁ c treatment strategies for a more optimal use of anti-EGFR therapy
Measurements of carbonyl sulfide in automotive emissions and an assessment of its importance to the global sulfur cycle

Carbonyl sulfide (OCS) is thought to be the major precursor to the background stratospheric aerosol sulfate layer during nonvolcanic time periods. Long-term perturbations to this layer from increased OCS emissions could significantly influence the Earth`s radiation budget, climate, and ozone levels. The present study was carried out in an effort to determine mass emission rates of OCS from automobiles, a potentially important global source of this gas. Studies were carried out on a variety of gasoline vehicles including those without catalytic converters, vehicles with older oxidation catalysts, and vehicles employing newer three-way catalysts. Preliminary measurements were also carried out on four diesel fuel cars and one medium-duty diesel fuel truck. Measurements of OCS were acquired by tunable diode laser absorption spectroscopy, and in most cases, measurements of CO were also acquired. Gasoline vehicles, which included some of the lowest and some of the highest CO emitters on the road today, revealed very high correlation between OCS and CO mass emission rates. The OCS-CO linear regression resulted in a slope of (5.8 {+-} 1.6) x 10{sup {minus}6} (gOCS/gCO) and a correlation coefficient of 0.92. The preliminary diesel fuel measurements resulted in a corresponding slope 34.5 times larger. On the basis ofmore » these results the authors calculated a global OCS source strength for gasoline and diesel fuel vehicles of 0.0008 to 0.008 Tg yr{sup {minus}1}. The upper limit is a factor of 100 to 600 times less important than the sum of all OCS sources. In contrast to the global scale, automotive emissions of OCS may be important on a local scale, particularly when attempting to measure background concentration and associated small secular trends. These OCS-CO ratios have been shown to be very useful in helping to delineate automotive sources from other sources. 32 refs., 6 figs., 3 tabs. « less
Managing Successful Organizational Change in the Public Sector

Can governmental organizations change? Reform initiatives have swept through governments in the United States and overseas, again and again bringing news about eff orts to reinvent, transform, or reform government agencies ( Barzelay 2001; Kettl 2000; Pollitt and Bouckaert 2000; Stillman 1999 ). Curiously, however, this recurrent theme of change in government agencies has not induced a high volume of articles that explicitly address the topic in public administration journals. Th ere are prominent exceptions to this observation (e.g., Bryson and Anderson 2000; Chackerian and Mavima 2000; Mani 1995; Wise 2002 ) and journal articles about topics related to organizational change (e.g., Berman and Wang 2000; Brudney and Wright 2002; Hood and Peters 2004 ). Articles reporting research and theory with titles containing “ organizational change ” and with that theme as a focal topic, however, appear with much less regularity in public administration journals than in research journals focusing on general management and organization theory.
Comparative genomic analysis of Lactobacillus crispatus strains Lc31 and Lc83 with anti-cervical cancer potential by complete genome sequencing

Lactobacillus crispatus is a commonly found species in the urogenital tract (UGT) of healthy females and can also colonize other niches, such as the gastrointestinal tract (GIT). Although its potential protective role in cervical cancer has been reported, the anticancer mechanisms involved are still unclear. In this study, we sequenced and characterized the complete genomes of two L. crispatus strains (Lc31 and Lc83) isolated from the UGT of healthy women of reproductive age. Phylogenetic and phylogenomic analyses of these two strains and 15 other L. crispatus strains with complete genome sequences revealed that strains from the UGT and GIT clustered separately. UGT strains had a larger genome size, higher GC contents, and more protein-coding sequences and insertion sequence (IS) elements, indicating the likelihood of active horizontal gene transfer in this niche. We found a universal presence of genes encoding bacteriocins and the absence of virulence factors and antibiotic resistance genes in UGT strains, suggesting the potential of L. crispatus as a urogenital probiotic. Comparative genomic analysis identified an ula gene cluster responsible for L-ascorbate catabolism exclusively in UGT strains, and carbohydrate fermentation experiments confirmed that this substrate supported the growth of L. crispatus Lc31 and Lc83. Our findings improve the understanding of how the genome determines niche adaptation by L. crispatus , providing a foundation for investigating the mechanisms by which urogenital-derived L. crispatus promotes female health.
Spatial heterogeneity in carbohydrates and their utilisation by microbial communities in the high North Atlantic

Carbohydrates in the ocean are chemically and structurally diverse, represent a substantial fraction of marine organic matter and are key substrates for enzymes of heterotrophic microbes. Our current understanding on microbial carbohydrate utilisation however, is largely derived from spring phytoplankton blooms in temperate regions. Here, we characterise the carbohydrate fraction of particulate organic matter (POM) and the utilisation of carbohydrates by marine microbes during late summer in high North Atlantic waters, using a combination of analytical techniques with metagenomics and metatranscriptomics. The composition and abundance of monosaccharides and varied detection of specific polysaccharide epitopes revealed high spatial and vertical heterogeneity. Complex polysaccharides, known to accumulate in POM over time, were consistently detected, whilst more labile, simple structures, such as β-1,3-glucan, exhibited patchy distribution, indicating local variations in primary productivity and rapid utilisation by microbes. Metatranscriptomics revealed the presence of active and dynamic bacterial populations, with distinct assemblages dominating carbohydrate utilisation across samples. Transcription of genes encoding carbohydrate-active enzymes revealed substrate-based niche
