Abstract:

We define the cover of an RG-module V to consist of an RG lattice Ṽ and a homomorphism π : Ṽ→ V such that π induces an isomorphism on Ext*RG(M, —) for any RG-lattice M. Here G is a finite group and, for simplicity in this introduction, R is a complete discrete valuation ring of characteristic zero with prime element p and perfect valuation class field. Let pn(G) be the highest power of p that divides |G| and, given an RG-lattice M, let pn(M) be the smallest power of p such that pn(M) idM : M→M factors through a projective lattice: n(M)≦n(G).

Abstract:

For a finite group G, by the endomorphism ring of a module M over a commutative ring R, we define a structure for M to make it an RG-module so that we study the relations between the properties of R-modules and RG-modules. Mainly, we prove that RadRM is an RG-submodule of M if M is an RG- module; also RadRM ? RadRGM where RadAM is the intersection of the maximal A-submodule of module M over a ring A. We also verify that M is an injective (projective) R-module if and only if M is an injective (projective) RG-module.

Abstract:

This work aims to establish a relationship between the photosynthetically active radiation (PAR) and the global radiation (Rg) for Santa Rita do Passa Quatro (SP), during the period from February 2005 to February 2006 and evaluate its impact on gross primary production (GPP). Data of Rg (Wm-2) and PAR (μmols s-1m-2) were obtained from the mirometeorological tower located in Gleba Cerrado Giant Foot. Data analysis allowed the establishment of a linear equation to express the relationship between PAR (MJ m-2) and Rg (MJ m-2) as: PAR = 0.3787 Rg or PAR = 1.742 Rg, for PAR (μmols s-1m-2) and Rg (MJ m-2). This relationship is indicated for the GPP determination when there is no PAR measurements.

Abstract:

Introduction. The incidence of Mycobacterium avium complex (MAC) pulmonary disease (MAC PD), a refractory chronic respiratory tract infection, is increasing worldwide. MAC has three predominant colony morphotypes: smooth opaque (SmO), smooth transparent (SmT) and rough (Rg). Aim. To determine whether colony morphotypes can predict the prognosis of MAC PD, we evaluated the virulence of SmO, SmT and Rg in mice and in human macrophages. Methodology. We compared the characteristics of mice and human macrophages infected with the SmO, SmT, or Rg morphotypes of M. avium subsp. hominissuis 104. C57BL/6 mice and human macrophages derived from peripheral mononuclear cells were used in these experiments. Results. In comparison to SmO- or SmT-infected mice, Rg-infected mice revealed severe pathologically confirmed pneumonia, increased lung weight and increased lung bacterial burden. Rg-infected macrophages revealed significant cytotoxicity, increased bacterial burden, secretion of proinflammatory cytokines (TNF-α and IL-6) and chemokines (CCL5 and CCL3), and formation of cell clusters. Rg formed larger bacterial aggregates than SmO and SmT. Cytotoxicity, bacterial burden and secretion of IL-6, CCL5 and CCL3 were induced strongly by Rg infection, and were decreased by disaggregation of the bacteria. Conclusion. M. avium Rg, which is associated with bacterial aggregation, has the highest virulence among the predominant colony morphotypes.

Abstract:

Abstract. The main drawback of the reconstruction of high-resolution distributed global radiation (Rg) time series in mountainous semiarid environments is the common lack of station-based solar radiation registers. This work presents 19 years (2000–2018) of high-spatial-resolution (30 m) daily, monthly, and annual global radiation maps derived using the GIS-based model proposed by Aguilar et al. (2010) in a mountainous area in southern Europe: Sierra Nevada (SN) mountain range (Spain). The model was driven by in situ daily global radiation measurements, from 16 weather stations with historical records in the area; a 30 m digital elevation model; and 240 cloud-free Landsat images. The applicability of the modeling scheme was validated against daily global radiation records at the weather stations. Mean RMSE values of 2.63 MJ m−2 d−1 and best estimations on clear-sky days were obtained. Daily Rg at weather stations revealed greater variations in the maximum values but no clear trends with altitude in any of the statistics. However, at the monthly and annual scales, there is an increase in the high extreme statistics with the altitude of the weather station, especially above 1500 m a.s.l. Monthly Rg maps showed significant spatial differences of up to 200 MJ m−2 per month that clearly followed the terrain configuration. July and December were clearly the months with the highest and lowest values of Rg received, and the highest scatter in the monthly Rg values was found in the spring and fall months. The monthly Rg distribution was highly variable along the study period (2000–2018). Such variability, especially in the wet season (October–May), determined the interannual differences of up to 800 MJ m−2 yr−1 in the incoming global radiation in SN. The time series of the surface global radiation datasets here provided can be used to analyze interannual and seasonal variation characteristics of the global radiation received in SN with high spatial detail (30 m). They can also be used as cross-validation reference data for other global radiation distributed datasets generated in SN with different spatiotemporal interpolation techniques. Daily, monthly, and annual datasets in this study are available at https://doi.org/10.1594/PANGAEA.921012 (Aguilar et al., 2021).

Abstract:

AbstractRotational grazing (RG) is a livestock management practice that rotates grazing cattle on a scale of hours to days among small pastures termed paddocks. It may beneficially affect stream channels, relative to other livestock management practices. Such effects and other beneficial effects on hydrology are important to RG's potential to provide a highly multifunctional mode of livestock farming. Previous comparisons of effects of RG and confinement dairy (CD) on adjoining streams have been restricted in scale and scope. We examined 11 stream-channel characteristics on a representative sample of 37 small dairy farms that used either RG or CD production methods. Our objectives were: (1) to compare channel characteristics on RG and CD farms, as these production methods are implemented in practice, in New York, Pennsylvania and Wisconsin, USA; and (2) to examine land use on these farms that may affect stream-channel characteristics. To help interpret channel characteristic findings, we examined on-farm land use in riparian areas 50 m in width along both sides of stream reaches and whole-farm land use. In all states, stream-channel characteristics on RG and CD farms did not differ. Whole-farm land use differed significantly between farm types; CD farms allocated more land to annual row crops, whereas RG farms allocated more land to pasture and grassland. However, land cover in 50 m riparian areas was not different between farm types within states; in particular, many RG and CD farms had continuously grazed pastures in riparian areas, typically occupied by juvenile and non-lactating cows, which may have contributed sediment and nutrients to streams. This similarity in riparian management practices may explain the observed similarity of farm types with respect to stream-channel characteristics. To realize the potential benefits of RG on streams, best management practices that affect stream-channel characteristics, such as protection of riparian areas, may improve aggregate effects of RG on stream quality and also enhance other environment, economic and social benefits of RG.

AbstractLet V be a vector space of dimension n over a field k of characteristic p. Let G ⊆ Gl(V) be a finite group with p-Sylow subgroup P. G and P act on the symmetric algebra R of V. Denote the respective rings of invariants by RG and Rp. We show that if Rp is Cohen-Macaulay (CM) so also is RG, generalizing a result of M. Hochster and J. A. Eagon. If P is normal in G and G is generated by P and pseudo-reflections, we show that if RG is CM so also is Rp. However, in general, RG may even be polynomial with Rp not CM. Finally, we give a procedure for determining a set of generators for RG given a set of generators for Rp.

A total of 19 local coconut populations were collected from some islands in Indonesia, planted at Pakuwon Experimental Garden, West Java in 1978 and 1982. The altitude is 450 meters above sea level with climate type Bl Oldeman. The total number of sample is 100 palms for each tall coconut with planting distance 9 x 9 m and 60 palms for each dwarf coconut with planting distance 7 x 7m. The observation was done in two steps i.e.: May - August 1996 on 14 populations and June - August 2000 on 5 populations when the coconut population was 18 years old. A number of 4 palms with 3 replications were observed of each population to measure morphological traits of he stem, leaf and inflorescence. Therefore, the total palms used in the experiment were 19 x 4 x 3 = 228. The results revealed that the genetic vaiability of coconut morphological trait were generally narrow. A few traits i.e.: stem diameter 1 5 m from ground level, stem length of 11 leaf scars, spadix without female flower, and number of female flowers/bunch showed a wide degree of variability. In general, the heritabilily estimates in broad sense and genetic gained in percent for all trails were high, except the henlability of spadix with female flower Irait was lowly. A positive significant genetic correlation were found to the morphology traits of stem with leaf and inllorcsccncc except Uic number of female flower/bunch and number of bunch/palm/ycar. From fifteen traits, only six traits had significant genetic correlation with the number of female flower Ihcy were diameter stem 1 5 m from ground level (rg 0.5215*), stem length of 11 leaf scars (rg - -0.5369'), leaflet width (rg - -0.5961**), peduncle thickness (rg 0.5802**), length of inflorescence (rg -0.6143**), and length of spadix (rg -0.4907*), and these traits could be used as selection criteria for selecting high female flower bunch on the coconut.Keywords ;Cocos nucifera. genetic parameters, correlation, mor- phological trails

O arcabouço estratigráfico pós-paleozoico da região de Manaus e Itacoatiara (Amazônia Central) foi elaborado com base em quatro seções geológicas contendo principalmente dados geofísicos e litológicos de 15 poços tubulares com até 300 m de profundidade, complementado com descrições de afloramentos. A definição de padrões específicos das curvas de raios gama natural (RG) e resistividade (RE) permitiu a individualização das unidades sedimentares inferior, intermediária e superior e seus contatos (descontinuidades S1 e S2). A unidade inferior, definida a partir da cota de -130 m, é constituída principalmente de folhelho, cujas repetições diagráficas das curvas de RG e RE caracterizam os padrões de curva tipos funil e serrilhado. A unidade intermediária, definida nas cotas entre 20 a -180 m, é constituída por intercalações de arenitos, pelitos e conglomerados, que geram repetições cíclicas de valores das diagrafias de RG e RE, gerando os padrões serrilhado e sino. A unidade superior, definida na cota de -30 m até a superfície do terreno, é constituída principalmente de arenitos com intercalações restritas de pelitos, que definem os padrões simétrico (curva de RG) e caixote (curvas de RE e RG). O posicionamento estratigráfico das unidades inferior, intermediária e superior nas seções, bem como o aspecto litológico e as relações com as superfícies limitantes, aliado a dados estratigráficos e geocronológicos regionais permitiram sua respectiva associação com as formações Nova Olinda-Andirá (Paleozoico), Alter do Chão (Cretáceo) e Novo Remanso (Neógeno) da Bacia do Amazonas.

Abstract:

AbstractWe derive an updated, analytic formula for the gravitational radius, rg, of an irradiated, thin disk. For such a disk, the region outside the gravitational radius will produce a thermal wind, while the region interior to the gravitational radius will be stable. We find that rg ≈ 1.4 (M*/M⊙)/(T0/104K) AU. The value of 1.4 AU is approximately one fifth of currently used values.The analysis uses the adiabatic approximation. We argue that the same formula applies for the non-adiabatic, isothermal case.

Abstract:

Objective: This study was conducted to evaluate the effect of red glasswort (RG) (Salicornia herbacea L.) curing on the physicochemical, textural and sensory properties of cooked pork loin ham (M. longissimus thoracis et lumborum).Methods: All treatments were cured with different salt and RG powder levels. RG0 treatment was prepared with only 4% NaCl (w/w) as a control, and RG25, 3% NaCl:1% RG (w/w); RG50, 2% NaCl:2% RG (w/w); RG75, 1% NaCl:3% RG (w/w); RG100, 0% NaCl:4% RG (w/w) treatments were prepared sequentially. All samples were individually vacuum packaged in polyethylene bags and stored for 7 d at 3°C±1°C.Results: The results showed that as the rate of RG substitution increased, pH value, redness, myofibrillar protein solubility, and myofibrillar fragmentation index increased (p<0.05), but salt concentration and shear force decreased (p<0.05). However, there were no significant differences in cooking loss and moisture content. In terms of sensory evaluation, RG100 exhibited higher scores in tenderness and juiciness than RG0 (p<0.05).Conclusion: The partial substitution of NaCl by RG could improve the physicochemical properties, textural and sensory characteristics of cooked pork loin. Therefore, it is suggested that RG as a natural salt replacer could be an effective ingredient for developing low-sodium cured hams.

Abstract:

Proliferation of mesangial cells (MC) is a key feature in the pathogenesis of numerous renal diseases involving the glomerulus. Heparin, one of several compounds capable of suppressing MC proliferation, did not prove beneficial in the treatment of human glomerular diseases. In a search for a superior antiproliferative agent, a synthetic polyaromatic "heparin mimicking" compound (RG-13577, polymer of 4-hydroxyphenoxy acetic acid, M(r) approximately 5800), previously reported to inhibit the proliferation of vascular smooth muscle cells, was applied. RG-13577 exhibits approximately 1% of the anticoagulant activity of heparin and is nontoxic in animal experiments. Proliferation of primary rat MC was almost completely inhibited in the presence of 10 to 25 micrograms/ml RG-13577, and 50% inhibition was obtained at 1 to 5 micrograms/ml RG-13577. The cells resumed their normal growth rate after removal of RG-13577 from the culture medium. Under the same conditions, heparin exerted only a small inhibitors effect. RG-13577 inhibited signaling (i.e., tyrosine phosphorylation) and MC proliferation induced by both basic fibroblast growth factor and platelet-derived growth factor. RG-13577 binds to a naturally produced extracellular matrix, and the bound molecule retained its antiproliferative effect toward MC. 14C-Labeled RG-13577 also binds to cultured MC in a specific and saturable manner. Binding of 14C-RG-13577 was reduced by 80 to 90% in the presence of excess unlabeled RG-13577, apolipoprotein E, or lactoferrin, but there was no effect with heparin. Furthermore, the antiproliferative effect of RG-13577 was abolished in the presence of lactoferrin. It is proposed that compound RG-13577 inhibits MC proliferation through neutralization of growth-promoting factors, primarily heparin-binding growth factors, and possibly through binding to specific cell surface receptors, most likely the LDL receptor-related protein. RG-13577 and related polyanionic compounds may be applied to inhibit MC proliferation in glomerular diseases.

Abstract:

Using immunocytochemical techniques and antibodies that specifically recognize xyloglucan (anti-XG), polygalacturonic acid/rhamnogalacturonan I (anti-PGA/RG-I), and methylesterified pectins (JIM 7), we have shown that these polysaccharides are differentially synthesized and localized during cell development and differentiation in the clover root tip. In cortical cells XG epitopes are present at a threefold greater density in the newly formed cross walls than in the older longitudinal walls, and PGA/RG-I epitopes are detected solely in the expanded middle lamella of cortical cell corners, even after pretreatment of sections with pectinmethylesterase to uncover masked epitopes. These results suggest that in cortical cells XG and PGA/RG-I are differentially localized not only to particular wall domains, but also to particular cell walls. In contrast to their nonoverlapping distribution in cortical cells, XG epitopes and PGA/RG-I epitopes largely colocalize in the epidermal cell walls. The results also demonstrate that the middle lamella of the longitudinal walls shared by epidermal cells and by epidermal and cortical cells constitutes a barrier to the diffusion of cell wall and mucilage molecules. Synthesis of XG and PGA/RG-I epitope-containing polysaccharides also varies during cellular differentiation in the root cap. The differentiation of gravitropic columella cells into mucilage-secreting peripheral cells is marked by a dramatic increase in the synthesis and secretion of molecules containing XG and PGA/RG-I epitopes. In contrast, JIM 7 epitopes are present at abundant levels in columella cell walls, but are not detectable in peripheral cell walls or in secreted mucilage. There were also changes in the cisternal labeling of the Golgi stacks during cellular differentiation in the root tip. Whereas PGA/RG-I epitopes are detected primarily in cis- and medial Golgi cisternae in cortical cells (Moore, P. J., K. M. M. Swords, M. A. Lynch, and L. A. Staehelin. 1991. J. Cell Biol. 112:589-602), they are localized predominantly in the trans-Golgi cisternae and the trans-Golgi network in epidermal and peripheral root cap cells. These observations suggest that during cellular differentiation the plant Golgi apparatus can be both structurally and functionally reorganized.

Abstract:

Carnitine palmitoyltransferase I (CPT I) is considered the rate-limiting enzyme in the transfer of long-chain fatty acids (LCFA) into the mitochondria and is reversibly inhibited by malonyl-CoA (M-CoA) in vitro. In rat skeletal muscle, M-CoA levels decrease during exercise, releasing the inhibition of CPT I and increasing LCFA oxidation. However, in human skeletal muscle, M-CoA levels do not change during moderate-intensity exercise despite large increases in fat oxidation, suggesting that M-CoA is not the sole regulator of increased CPT I activity during exercise. In the present study, we measured CPT I activity in intermyofibrillar (IMF) and subsarcolemmal (SS) mitochondria isolated from human vastus lateralis (VL), rat soleus (Sol), and red gastrocnemius (RG) muscles. We tested whether exercise-related levels (∼65% maximal O2 uptake) of calcium and adenylate charge metabolites (free AMP, ADP, and Pi) could override the M-CoA-induced inhibition of CPT I activity and explain the increased CPT I flux during exercise. Protein content was ∼25-40% higher in IMF than in SS mitochondria in all muscles. Maximal CPT I activity was similar in IMF and SS mitochondria in all muscles (VL: 282 ± 46 vs. 280 ± 51; Sol: 390 ± 81 vs. 368 ± 82; RG: 252 ± 71 vs. 278 ± 44 nmol·min-1·mg protein-1). Sensitivity to M-CoA did not differ between IMF and SS mitochondria in all muscles (25-31% inhibition in VL, 52-70% in Sol and RG). Calcium and adenylate charge metabolites did not override the M-CoA-induced inhibition of CPT I activity in mitochondria isolated from VL, Sol, and RG muscles. Decreasing pH from 7.1 to 6.8 reduced CPT I activity by ∼34-40% in both VL mitochondrial fractions. In summary, this study reports no differences in CPT I activity or sensitivity to M-CoA between IMF and SS mitochondria isolated from human and rat skeletal muscles. Exercise-induced increases in calcium and adenylate charge metabolites do not appear responsible for upregulating CPT I activity in human or rat skeletal muscle during moderate aerobic exercise.

Abstract:

Greenhouse experiments were conducted to evaluate the effect of the fungusDactylaria higginsiion the interference ofCyperus rotundus(purple nutsedge) withLycopersicon esculentum(tomato ‘Agroset').Cyperus rotundusplants established from tubers were planted at initial densities equivalent to 40, 80, 160, and 320 tubers m−2withL. esculentumin 35-cm-diam pots.Cyperus rotundusplants were inoculated by spraying with a spore suspension ofD. higginsiicontaining 0.5% Metamucil as a carrier. The treatments were Metamucil only, 104conidia ml−1+ Metamucil, or 106conidia ml−1+ Metamucil. In the absence ofD. higginsii, C. rotundusat densities of 80, 160, and 320 tubers m−2reducedL. esculentumyield by 14, 68, and 70%, respectively. In contrast, yield ofL. esculentumtreated withD. higginsiiat 106conidia ml−1was equal to that in the weed-free control. The rate of disease increase (rG) was higher in treatments with 106conidia ml−1(rG= 0.126 to 0.136) compared to 104conidia ml−1(rG= 0.046 to 0.050). At 106conidia ml−1D. higginsiireduced the interference fromC. rotundus, controlledC. rotundusbetter, and increasedL. esculentumyield compared to the weedy checks.

Abstract:

In the food industry and herbal markets, it is critical to control the quality of processed Panax ginseng products. In this study, ultra-performance liquid chromatography coupled to quadrupole time of flight mass spectrometry (UPLC-QTOF/MS)-based metabolomics was applied for the quality evaluation of white ginseng (WG), tae-geuk ginseng (TG), red ginseng (RG), and black ginseng (BG). Diverse metabolites including ginsenosides were profiled by UPLC-QTOF/MS, and the datasets of WG, TG, RG, and BG were then subjected to multivariate analyses. In principal component analysis (PCA), four processed ginseng products were well-differentiated, and several ginsenosides were identified as major components of each product. S-plot also characterized the metabolic changes between two processed ginseng products, and the major ginsenosides of each product were found as follows: WG (M-Rb1, M-Rb2, M-Rc, Re, Rg1), TG (Rb2, Rc, Rd, Re, Rg1), RG (Rb1, Rb2, Rc, Rd, Re, Rg1), and BG (Rd, Rk1, Rg5, Rg3). Furthermore, the quantitative contents of ginsenosides were evaluated from the four processed ginseng products. Finally, it was indicated that the proposed metabolomics approach was useful for the quality evaluation and control of processed ginseng products.

Abstract:

The sympathetic nervous system has greater influence on vascular resistance in low-oxidative, fast-twitch skeletal muscle than in high-oxidative skeletal muscle (17). The purpose of this study was to test the hypothesis that arterioles isolated from low-oxidative, fast-twitch skeletal muscle [the white portion of gastrocnemius (WG)] possess greater responsiveness to adrenergic constriction than arterioles isolated from high-oxidative skeletal muscle [red portion of the gastrocnemius muscle (RG) and diaphragm (Dia)]. Second-order arterioles (2As) were isolated from WG, RG, and Dia of rats and reactivity examined in vitro. Results reveal that Dia 2As constrict less to norepinephrine (NE) (10−9 to 10 −4 M) than 2As from RG and WG, which exhibited similar NE-induced constrictions. This difference was not endothelium dependent, because responses of denuded 2As were similar to those of intact arterioles. The blunted NE-induced constrictor response of Dia 2As appears to be the result of differences in α1-receptor effects because 1) arterioles from Dia also responded less to selective α1-receptor stimulation with phenylephrine than RG and WG arterioles; 2) arterioles from Dia, RG, and WG dilated similarly to isoproterenol (10−9 to 10−4 M) and did not respond to selective α2-receptor stimulation with UK-14304; and 3) endothelin-1 produced similar constriction in 2As from Dia, RG, and WG. We conclude that differences in oxidative capacity and/or fiber type composition of muscle tissue do not explain different NE responsiveness of Dia 2As compared with 2As from gastrocnemius muscle. Differences in α1-adrenergic constrictor responsiveness among arterioles in skeletal muscle may contribute to nonuniform muscle blood flow responses observed during exercise and serve to maintain blood flow to Dia during exercise-induced increases in sympathetic nerve activity.

Abstract:

Abstract. This paper describes the validation of the SimSphere SVAT (Soil–Vegetation–Atmosphere Transfer) model conducted at a range of US and Australian ecosystem types. Specific focus was given to examining the models' ability in predicting shortwave incoming solar radiation (Rg), net radiation (Rnet), latent heat (LE), sensible heat (H), air temperature at 1.3 m (Tair 1.3 m) and air temperature at 50 m (Tair 50 m). Model predictions were compared against corresponding in situ measurements acquired for a total of 72 selected days of the year 2011 obtained from eight sites belonging to the AmeriFlux (USA) and OzFlux (Australia) monitoring networks. Selected sites were representative of a variety of environmental, biome and climatic conditions, to allow for the inclusion of contrasting conditions in the model evaluation. Overall, results showed a good agreement between the model predictions and the in situ measurements, particularly so for the Rg, Rnet, Tair 1.3 m and Tair 50 m parameters. The simulated Rg parameter exhibited a root mean square deviation (RMSD) within 25 % of the observed fluxes for 58 of the 72 selected days, whereas an RMSD within ~ 24 % of the observed fluxes was reported for the Rnet parameter for all days of study (RMSD = 58.69 W m−2). A systematic underestimation of Rg and Rnet (mean bias error (MBE) = −19.48 and −16.46 W m−2) was also found. Simulations for the Tair 1.3 m and Tair 50 m showed good agreement with the in situ observations, exhibiting RMSDs of 3.23 and 3.77 °C (within ~ 15 and ~ 18 % of the observed) for all days of analysis, respectively. Comparable, yet slightly less satisfactory simulation accuracies were exhibited for the H and LE parameters (RMSDs = 38.47 and 55.06 W m−2, ~ 34 and ~ 28 % of the observed). Highest simulation accuracies were obtained for the open woodland savannah and mulga woodland sites for most of the compared parameters. The Nash–Sutcliffe efficiency index for all parameters ranges from 0.720 to 0.998, suggesting a very good model representation of the observations. To our knowledge, this study presents the most detailed evaluation of SimSphere done so far, and the first validation of it conducted in Australian ecosystem types. Findings are important and timely, given the expanding use of the model both as an educational and research tool today. This includes ongoing research by different space agencies examining its synergistic use with Earth observation data towards the development of global operational products.

El maíz dosmesano (Zea mays L.) es un tipo de maíz nativo utilizado en el sistema milpa de Tabasco, México, apreciado por su calidad de tortilla y por su gran adaptación a las condiciones del trópico mexicano. Es necesario generar recomendaciones de manejo agronómico para mejorar su aprovechamiento. El objetivo de este estudio fue evaluar el potencial productivo del maíz tropical dosmesano nativo de Tabasco, México bajo diferentes densidades de población, generadas con variantes de arreglos topológicos de distancia entre surcos (0.8 y 1.0 m), distancia entre matas (0.20 y 0.25 m) y número de semillas por mata (una y dos); adicionalmente, se incluyeron un testigo regional (TR) a 1.0 m entre surcos, 1.0 m entre matas y cuatro semillas/mata, y otro modificado (TRM) con 0.8 m entre surcos, 1.0 m entre matas, cuatro semillas/mata. Se utilizó un diseño experimental de bloques completos al azar con tres repeticiones, con arreglo factorial de tratamientos. Se registraron las variables días después de la siembra a 50 % de floración masculina (50 % FM) y 50 % de floración femenina (50 % FM), altura de mazorca (AM, cm), altura de planta (AP, cm), relación AP/AM, porcentaje de acame (PA), relación (AP/AM)/PA, porcentaje de plantas jorras (PPJ), porcentaje de prolificidad (PP) y rendimiento de grano (RG, kg ha-1). Se detectó interacción significativa de distancia entre surcos × número de semillas/mata para RG (P ≤ 0.01) y PPJ (P ≤ 0.01). El mayor RG (3869 kg ha-1) se observó en 1.0 m de distancia entre surcos y dos semillas por mata, con 80,000 plantas ha-1, y superó a TR que rindió 2198 kg ha-1. El mayor PPJ, 73 %, se observó en distancia entre surcos de 0.8 m y dos semillas por mata. Hubo triple interacción significativa en AP (P ≤ 0.01) y AM (P ≤ 0.01), ambas con distancia entre surcos de 0.8 m, distancia entre matas de 0.2 m y una semilla por mata, con media de 2.67 y 1.26 m, respectivamente. Existió efecto simple significativo del número de semillas por mata para PP (P ≤ 0.05), con 17 y 4 %, con una y dos semillas por mata, respectivamente. No se detectaron efectos significativos para 50 % FM, 50 % FF, PA, en la relación AP/AM y (AP/AM)/PA (P > 0.05). El RG observado indica alto potencial del cultivo bajo alta densidad poblacional, en comparación con el sistema tradicional de siembra.

Abstract:

The paper discusses geomorphology of the Sunda Trench, an oceanic trench located in eastern Indian Ocean along the Sumatra and Java Islands of the Indonesian archipelago. In particular, it analysis the difference in depths and variation in slope steepness between the two segments of the trench: the southern Java transect (coordinates 108.8°E 10.10°S to 113.0°E 10.75°S) and the northern Sumatra transect (97.5°E 1.1°S to 101.0°E 5.5°S). The thematic maps and geomorphological modelling were plotted using Generic Mapping Tools (GMT). The materials include high-resolution data on topography, geology and geophysics: GEBCO 15 arc-minute resolution grid, EGM2008 2.5 minute Earth Gravitation Model of 2008, GlobSed global 5‐arc‐minute total sediment thickness and vector geological datasets. In addition to the GEBCO-based bathymetric data, geological, topographic and geophysical maps, the results include enlarged transects for the Java and Sumatra segments, their slope gradients and cross-section profiles, derived from the bathymetric GEBCO dataset. The geomorphology framework of the Sunda Trench is largely controlled by the subduction of the Australian plate underneath the Sunda microplate. The geological processes take place in basin of the Indian Ocean at different stages of its evolution and influence the nature of the submarine geomorphology and geometric shape of the trench. Sunda Trench is seismically active part of the Pacific Ring of Fire. A large number of the catastrophic earthquakes are recorded around the trench. The histograms shows variation in depths along the segments of the Sumatra and Java. The Java segment has a bell-shaped data distribution in contrast to the Sumatra with bimodal pattern. The Java segment has the most repetitive depths at -2,500 to -5,200 m. The Sumatra transect has two peaks: 1) a classic bell-shaped peak at depths -4,500 m to -5,500 m; 2) shelf area with a peak from 0 to -1,750 m. The data at middle depths (-1,750 to -4,500 m) have a frequency <300 samples. The most frequent bathymetry for the Sumatra segment corresponds to the -4,750 m to -5,000 m (2,151 samples). Comparing to the Sumatra segment, the Java segment is deeper. For the depths >-6,000 m, there are only 138 samples for the Sumatra while 547 samples for Java. Furthermore, Java segment has more symmetrical geometric shape while Sumatra segment is asymmetric, one-sided. The Sumatra segment has a steepness of 57.86° on its eastern side (facing Sumatra Island) and a contrasting 14.58° on the western part. The Java segment has a steepness of 64.34° on its northern side (facing Java Island) and 24.95° on the southern part (facing Indian Ocean). The paper contributes to the studies of the submarine geomorphology in Indonesia.

Objetivou-se com este trabalho a obtenção de modelos para a estimativa do saldo de radiação (Q*) a partir da radiação solar global incidente (Rg) sobre dosseis de plantas de girassol. Os experimentos foram conduzidos na área experimental da Universidade Federal de Santa Maria, nos anos de 2007, 2008 e 2009. O Q* foi medido com saldos radiômetros instalados acima das plantas e a Rg em estações meteorológicas automáticas. Para fins de cálculo foram efetuadas as somas diárias de Q* e de Rg, obtendo-se a relação entre Q* e Rg para cada dia. Obtiveram-se, então, modelos com elevado coeficiente de determinação e baixo RQME no teste entre valores medidos e estimados de um banco de dados independente, indicando precisão na estimativa do saldo de radiação em dosseis de girassol, independendo da época de cultivo no ano. A função linear geral obtida com dados de diferentes épocas de cultivo foi: Q* = 0,5285 Rg (R² = 0,95), que no teste apresentou RQME = 1,04 MJ m-2 d-1. Conclui-se que o saldo de radiação (Q*) pode ser estimado utilizando-se a radiação solar global medida em estações automáticas, com precisão suficiente para os diferentes fins na agrometeorologia do girassol.

Abstract:

High-alpine caves are currently in the spotlight of research as they are host to speleothems, key recorders of Quaternary environmental change. Based on modern survey and analytical techniques, we investigated the karst morphology of M3-R2 Cave, the highest alpine cave in the Romanian Carpathians. Spatial modeling in Compass has shown survey details and cave morphology. We recalculated the main cave parameters (development/extension/depth), obtaining 47 m/21 m/-18.15 m, respectively. Slope ranges between 25° and 45°, with short passage segments of 5° to 10°. The cave developed at the intersection of a SW-dipping schistosity plan with two fracture sets, occurred under compression conditions. It is a remnant of a once longer cave system, which was progressively eroded under glacial conditions. Speleothem diversity is uncommonly rich for a marble cave, with dominant moonmilk formations, stalagmites and draperies. Due to its location/elevation, evolution and speleothems, this cave has a great potential in providing important paleoclimatic information compared to other karst landforms in South Carpathians.

Abstract:

Quantum many-body problem with exponentially large degrees of freedom can be reduced to a tractable computational form by neural network method [G. Carleo and M. Troyer, Science 355 (2017) 602, arXiv:1606.02318.] The power of deep neural network (DNN) based on deep learning is clarified by mapping it to renormalization group (RG), which may shed lights on holographic principle by identifying a sequence of RG transformations to the AdS geometry. In this paper, we show that any network which reflects RG process has intrinsic hyperbolic geometry, and discuss the structure of entanglement encoded in the graph of DNN. We find the entanglement structure of DNN is of Ryu–Takayanagi form. Based on these facts, we argue that the emergence of holographic gravitational theory is related to deep learning process of the quantum-field theory.

Abstract:

Low-density lipoproteins (LDL) in plasma are constructed from a single molecule of apolipoprotein B-100 (M(r) 512000) in association with lipid (approximate M(r) 2-3 x 10(6)). The gross structure was studied using an updated pulsed-neutron camera LOQ with an area detector to establish the basis for the interpretation of structural changes seen during dynamic studies of LDL oxidation. Neutron-scattering data for LDL in 100% 2H2O buffers emphasize their external appearance. Guinier analysis on a continuous-flux neutron camera D17 revealed pronounced concentration-dependences in the radius of gyration, RG, and the intensity of forward scattering, I(0) (equivalent to the M(r) of LDL) between 0.5 and 11 mg of LDL protein/ml. LDL preparations from different donors gave different RG values. When extrapolated to zero concentration, RG values ranged between 8.3 and 10.6 nm and were linearly correlated with M(r), which is consistent with a spherical structure. The distance-distribution function P(r) in real space showed a single maximum at 9.1-10.9 nm, which is just under half the observed maximum dimension of 23.1 +/- 1.2 nm expected for a spherical structure. The neutron radial-density function p(r) exhibited a plateau of high and featureless density at the centre of LDL. LDL can be modelled by a polydisperse assembly of spheres with two internal densities and a mean radius close to 10.0 nm in a normal distribution of radii with a standard deviation of 2.0 nm. The data are consistent with recent electron-microscopy and ultracentrifugation data.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract:

Abstract Improved and unimproved roads can be the primary source of stream sediment in forested watersheds. We assessed differences in production of total suspended solids (TSS; ppm) from four road surface conditions in a Southern Appalachian watershed: (1) a 2-yr-old paved surface (P), (2) an improved gravel surface with controlled drainage and routine maintenance (RG), (3) an improved gravel surface with erosion and sediment control structures installed and routine maintenance (IG), and (4) an unimproved poorly maintained gravel surface (UG). Variation was high among and within road surface types. The P surface generated the least amount of TSS, which was comparable to control sites, while the UG surface generated the most. The P surface produced significantly less TSS than the UG surface, but not less than the IG and RG surfaces. Variation among road surface types was related to TSS travel distance below the road, precipitation amount, time of year, and the existence of functioning erosion and sediment control structures. TSS decreased with travel distance (P = -81% over 38.5 m, IG = -30% over 30.5 m, RG = -89% over 39.4 m, and UG = -22% over 28.1 m). Also in this study we assessed the delivery of total petroleum hydrocarbons (TPH; ppm) from the P surface and found concentrations of < 0.5 ppm, which are well below published USEPA and NC DENR TPH standards for sediment. Paving is an attractive option for reducing maintenance costs and sediment production and transport; however, levels of TPH from freshly applied asphalt are unknown. South. J. Appl. For. 27(2):100–106.

Abstract:

84 Background: Although nivolumab (NIVO) and irinotecan (IRI) are recognized as standard third-line and further treatments for patients (pts) with advanced gastric cancer (AGC), the drug that should be administered first remains unclear. Conversely, tumor growth rate (TGR) during preceding treatment was associated with tumor response to regorafenib or trifluridine/tipiracil in colorectal cancer. Methods: We retrospectively evaluated 212 pts with AGC treated with NIVO or IRI for the first time between January 2015 and June 2018 at three institutions. The main inclusion criteria were ECOG PS of 0–2, prior use of fluoropyrimidines and taxanes, and no prior use of NIVO or IRI. Pts were classified into slow- (SG) and rapid- (RG) growing groups according to TGR and presence or absence of new lesions (NL) during preceding treatment. TGR = (D1 − D0)/100D0 (CT1 − CT0), where CT1 is the date of CT at PD during preceding treatment, CT0 is the date of CT before CT1, and Dn is the sum of target lesion diameters at CTn. SG and RG were defined as NL− with low TGR and NL− with high TGR or NL+, respectively. TGR cut-off value was defined as a median TGR of 0.30%/day. Results: A total of 117 pts (RG/SG, 72/45; NIVO/IRI, 32/85) were eligible. Almost all baseline characteristics were similar between the NIVO and IRI groups among the RG or SG, whereas the proportion of pts with peritoneum metastases was higher in the NIVO group than in the IRI group among the RG. The response rate (RR) was significantly higher with NIVO than with IRI [31% vs. 3%, odds ratio (OR): 13.8, p = 0.01; adjusted OR (aOR): 52, p = 0.002] among the SG, whereas it was comparable between both drugs (5% vs. 8%, OR: 0.68, p = 0.73; aOR: 0.94, p = 0.96) among the RG. PFS was longer with NIVO than with IRI [median PFS (mPFS) 4.2 vs. 1.9 months (m), hazard ratio (HR): 0.50, p = 0.10] among the SG, whereas it was shorter with NIVO than with IRI (mPFS 1.6 vs. 2.1 m, HR: 1.37, p = 0.28) in the RG. Conclusions: RR was higher with NIVO than with IRI among slow growing tumors, whereas it was comparable between both drugs among rapid growing tumors. TGR during preceding treatment might be helpful for drug selection in pts with AGC who are considered for treatment with NIVO or IRI.

Abstract:

ABSTRACT Mutations of the conserved residues of influenza virus neuraminidase (NA) that are associated with NA inhibitor (NAI) resistance decrease the sialidase activity and/or stability of the NA, thus compromising viral fitness. In fact, clinically derived NAI-resistant variants with different NA mutations have shown different transmissibilities in ferrets (M. L. Herlocher, R. Truscon, S. Elias, H. Yen, N. A. Roberts, S. E. Ohmit, and A. S. Monto, J. Infect. Dis. 190:1627-1630, 2004). Molecular characterization of mutant viruses that have a homogeneous genetic background is required to determine the effect of single mutations at conserved NA residues. We generated recombinant viruses containing either the wild-type NA (RG WT virus) or a single amino acid change at NA residue 119 (RG E119V-NA virus) or 292 (RG R292K-NA virus) in the A/Wuhan/359/95 (H3N2) influenza virus background by reverse genetics. Both mutants showed decreased sensitivity to oseltamivir carboxylate, and the RG R292K-NA virus showed cross-resistance to zanamivir. We also observed differences between the two mutants in NA enzymatic activity and thermostability. The R292K mutation caused greater reduction of sialidase activity and thermostability than the E119V mutation. The NA defect caused by the R292K mutation was associated with compromised growth and transmissibility, whereas the growth and transmissibility of the RG E119V-NA virus were comparable to those of RG WT virus. Our results suggest that NAI-resistant influenza virus variants may differ substantially in fitness and transmissibility, depending on different levels of NA functional loss.

Abstract:

Abstract In August and September of 1997, three 25-ton chemical explosions were detonated at nominal depths of 550, 300, and 50 m in boreholes at the former Soviet test site at Balapan, Kazakhstan. One objective of this experiment was to evaluate the effect of differing source depth on the regional wave field. Analysis of regional seismic phases lead to the observation that regional P/S wave amplitude ratios in the 1- to 5-Hz band increase as a function of source depth. However, at frequencies greater than about 5 Hz, the relative amplitudes of P and S waves remain approximately constant for the differing depth shots. Similarly, regional coda spectra are amplified in the 1- to 5-Hz band for the shallow shots. At local distances, Rg is the dominant seismic phase, with peak amplitudes in the 0.7- to 5-Hz range, and Rg is strongest for the shallower shots. Within the short distance spanned by the local stations (<20 km), Rg is rapidly attenuated, and the attenuation is accompanied by a significant shift in peak amplitude toward lower frequency. At regional distances, Rg is below the noise level. The coincident frequency band in which local Rg rapidly loses energy and regional S phases are amplified points toward Rg scattering as the dominant mechanism causing the discrepancies between P/S amplitude ratios in this study. These observations are particularly relevant to the understanding of physical processes affecting regional P/S discriminants and may lead to improvements in discriminant methods.

Abstract:

ABSTRACT Objective The aim of this study was to assess the incidence of micronuclei (MN) in buccal mucosal cells of professionals working in radiology area to determine the risk of stochastic effects of radiation. Materials and methods All the professionals and students working in King Khalid University - College of Dentistry radiology area were included in the Risk Group (RG = 27). The Control Group (CG = 27) comprised of healthy individual matching the gender and age of the RG. Buccal mucosal scraping from all the 54 subjects of RG and CG were stained with Papanicolaou stain and observed under oil immersion lens (×100) for the presence of micronuclei (MN) in the exfoliated epithelial cells. Results There was no significant difference between the incidence of MN in RG and CG (p = >0.05) using t-test. Conclusion Routine radiation protection protocol does minimize the risk of radiation induced cytotoxicity, however, screening of professionals should be carried out at regular intervals.

Abstract:

Abstract Over 9000 records of teleseismic P-wave coda from the Southern California Seismic Network are used to map lateral variations in P to Rg scattering strength and the group velocity of scattered Rg. Building on the results of Revenaugh (1995a), we use the correlation of scattering strength and topographic roughness as an indicator of model fit to estimate group-velocity dispersion over five frequency bands between 0 and 3 Hz. Rg group velocity displays normal dispersion, decreasing from 2.7 ± 0.3 km/sec for frequencies between 0 and 0.6 Hz to a low of 2.2 ± 0.4 km/sec for the 2.0 to 3.0 Hz band. Lateral heterogeneity is introduced by assuming Rg velocity is a function of local topographic roughness. Grid-search/migration analysis yields group velocities of 2.2 and 2.85 km/sec for “smooth” and “rough” terrain, respectively, and a 150-m threshold for the local standard deviation of topography distinguishing “smooth” from “rough”. The map of scattering strength approximates topographic roughness throughout southern California, implying that teleseismic P-wave coda duration and relative amplitude level depend strongly on near-surface (<3 km) geology.
