Abstract:

The paper suggests and examines a simplified relative indicator of forest production, with special regard to possibilities of its use in projecting future forests. Forest yield index (<I>I</I><sub>Y</sub>), based on an economic parameter “value of final cutting yield” was proposed, and examined in the model territory of Kysuce in north-western Slovakia. The current values of final cutting yield, dependent on tree species, site index and the length of rotation period served as a basis for the assessment of expected yields. The possibilities and limitations of index appli

To identify tolerant genotypes using yield and yield-based indices, a comprehensive investigation was conducted in a factorial fashion of 56 wheat genotypes under two water regimes (control and drought) over two distinct growi

Abstract:

Abstract This paper explores the environmental requirements and site selection of Ficus carica. The ideal conditions for dried fig production are: temperate and rainy winters, 30-40°C summer temperatures especially in July-September, 45-50% relative humidity, alluvial, clayish-loam soil, and average annual precipitation of around 650 mm. Growing fig trees in intensive production systems under hydroponic and greenhouse conditions is an excellent alternative production system since it allows increasing leaf area index, harvest index and fruit yield in relation to the total biomass of the plant. In site selection for greenhouse production, most of the same factors as used in siting an orchard location should be considered: topography, soil and water quantity and quality, and marketing factors. In addition, the most important greenhouse factors such as light, temperature, relative humidity, precipitation and ventilation should be considered, as well as the most important marketing or economic factors such as road transportation, market accessibility (proximity to settlements, market demands), availability of services (fuel, fertilizer, disinfectant and electricity), and availability of labor.

Abstract:

Abstract Cold stress is a common factor affecting rice culture in temperate regions, which impairs seed germination, crop establishment and grain yield. This work aimed to identify, through a TILLING assay, rice mutant families displaying cold tolerance during the germination stage. The mutant analyses were performed in 4000 M<sub>3</sub> plants obtained through chemical mutagenesis with ethyl methanesulfonate. We screened for mutations in the Os03g0103300 (qLTG3-1) gene, which is responsible for cold tolerance during germination. The TILLING assay identified a mutant (516 A3) which was tested for germination efficiency in cold stress (13°C). The mutant genotype showed a higher relative performance in germination and germination velocity index, which was more than 50% higher compared with wild-type. The mutation induction was efficient in creating genetic variability for cold stress tolerance during germination. Gene expression analyses demonstrate that Os03g0103300 was downregulated in stage S3 in the mutant and wild-type plants germinated under cold stress. However, downregulation in the Os03g0103300 gene was less severe in the mutant, which suggests that the expression related to germination ability under cold stress may be detected in the previous stages, embryo activation and weakening of the tissues that cover the embryo. Overall, the mutant 516 A3 presents a new genetic variant for cold tolerance during germination.

Abstract:

AbstractClimate change and climate variability in Malawi have negatively affected the production of maize, a staple food crop. This has adversely affected food security. On the other hand, there have been increases in growing area, production, yield, consumption, and commercialization of both cassava and sweet potato. Factors behind these increases include the adaptive capacity of these crops in relation to climate change and variability, structural adjustment programs, population growth and urbanization, new farming technologies, and economic development. Cassava and sweet potato are seen to have the potential to contribute to food security and alleviate poverty among rural communities.This study used a simple generic growth index model called GROWEST to model observed yields of maize, cassava, and sweet potato across Malawi between 2001 and 2012. The method can be viewed as a hybrid approach between complex process-based crop models and typical statistical models. For each food crop, the GROWEST model was able to provide a robust correlation between observed yields and spatially interpolated monthly climate. The model parameters, which included optimum growing temperatures and growing seasons, were well determined and agreed with known values. This indicated that these models could be used with reasonable confidence to project the impacts of climate change on crop yield. These projections could help assess the future of food security in Malawi under the changing climate and assist in planning for this future.

Abstract:

Abstract This chapter focuses on developing general model of community growth and the production of yield by grain crops. Murata's (1969) three-stage system provides such a model. It is useful because it is simple (only three stages), it applies equally well to all grain crop species (although there are some species variation in minor details), it clearly identifies the sequential nature of the yield production process and the three stages relate to the primary drivers of the yield production process at the community level. First, the crop must accumulate the leaf area that drives community photosynthesis (Stage I), then seed number is determined (Stage II), and finally seed filling occurs (Stage III) and the production of yield is finished. High yield of any variety/location combination requires, at a minimum: (i) the production of enough leaf area index (LAI) during Stage I to maximize solar radiation interception and community photosynthesis; and (ii) an absence of stress during Stage II to maximize seed number and during Stage III to allow the seeds to fill to their maximum potential size. The scheme provides a powerful framework for us to think about how management decisions and environmental conditions affect yield.

Abstract:

The aim of the research was to evaluate the influence of the type of the nervous system on the productive and reproductive qualities of animals. The type of nervous system (strong, weak) of cows of the Ukrainian red dairy breed was determined by the index of the nervous system, which is based on the variability of the fat content in the morning milk yield after changing the conditions of cows keeping. Under the new conditions of keeping cows with a strong type of nervous activity, the coefficients of variability of the morning milk yield and the fat content in milk practically remained at the same level (their slight increase was noted at the level of 4.5 and 3.1%). In cows of a weak type under similar conditions of keeping, a significant increase in the variability of milk yield (by 53.6%) and fat content in milk (by 266.7%) was found. In animals of both types, in the first days of summer-camp keeping, in comparison with winter-stall keeping, there was an increase in milk yield and a decrease in fat content in milk. In cows of the strong type, the fat content decreased by 0.08% and of the weak type by 0.12%. The average index of the nervous system type in animals of the strong type is 1.18, and in cows of the weak type 2.71 (P> 0.999). Before and during milking, the pulse rate in the cows of weak type was higher by 8.0 and 10.8 beats / min. (P> 0.999), compared with the strong type. The animals of strong type of the nervous system, in comparison with the weak type, had a smaller thickness of the concha and skin, a higher pulse and respiratory rate, and a lower rectal body temperature. In cows of a strong type of the nervous system in postnatal ontogenesis, the formation of productive traits took place more rapidly and they better adapted to the conditions of the external environment. This is evidenced by their high coefficient of relative decline in the growth at the age of one (85.0) than in animals with a weak type of nervous system (78.5). The advantage of cows with a strong type of nervous activity over a weak one in milk yield was 348 kg (P>0.95) and in milk fat 8.0 kg. The service period in animals with a strong type of nervous activity was 6.3 days shorter. The animals with a strong type of nervous activity during the first lactation had a higher adaptation index compared with animals of a weak type. The difference for this indicator is 0.49 (or 3.7%). They also had a higher productivity index for the first (3.1%) and second (4.0%) lactation. Thus, the typological features of the nervous activity of cows affect the formation of the most important functions of the body, which can be used in breeding work to improve the herd.

Abstract:

Over the decades in the medicinal field, biopolymers derived from natural resources have found tremendous applications in various fields such as medical, pharmaceutical, food packaging applications owing to their unique characteristics. Significantly, cellulose reinforced polymeric matrix containing smaller size fibers exhibits enhanced physical, mechanical and biological properties in contrast to the pristine polymeric matrix having greater pore size fibers. In this present study, cellulose was extracted from the crop residue of rice husk waste using a feasible chemical treatment. The surface morphological investigation and the particle size of the product cellulose were determined. Fourier transform infrared (FT-IR) spectra of the cellulose revealed that the non-cellulosic constituents from the product have removed effectively. X-ray diffraction (XRD) analysis revealed the three main diffraction peaks at 2 values of 17.8o, 22.7o, and 34.4o relative to the cellulose crystalline structure and the crystallinity index of the product cellulose was calculated to be 70 ±3 %. Thermo gravimetric analysis (TGA) showed that the crystalline cellulose decomposed at 333oC with no additional peaks indicating the purity of the extracted product. These results showed that the extracted cellulose possessed significant thermal stability and higher yield which could be used for advanced biocomposite nanofiber which could be utilised in the packaging applications.

Abstract:

Abstract Development of predictive models to estimate the distribution and petrophysical properties of potential mudstone-flow barriers can reduce risks inherent to exploration and exploitation programs. Such a predictive model, founded in sequence stratigraphy, requires calibration with outcrop and subsurface analogs. Detailed sedimentological, petrophysical, and geochemical analyses of Lewis Shale (lower Maastrichtian) samples from southeast Wyoming reveal considerable variability in petrophysically and seismically significant rock properties. Lower Lewis strata represent late-stage transgressive deposits that include a distinctive condensed interval. The overlying progradational Lewis interval consists mostly of interstratified very silty shales and argillaceous siltstones. High-frequency sheet and lenticular sandstone bodies occur in the progradational Lewis package. Sealing capacity, as measured by mercury injection-capillary pressure (MICP) analysis, varies with fabric, texture, and compositional factors that are related to sequence-stratigraphic position. Samples from the Lewis Shale transgressive interval have significantly greater MICP values (average 18,000 psia) and are markedly better seals relative to samples from the overlying Lewis Shale progradational package (average 3000 psia). Transgressive shales with enhanced sealing capacity are characterized by higher total organic carbon and hydrogen index values, lower permeability, and lower detrital silt content. These transgressive shales are enriched in iron-bearing clay minerals and authigenic pyrite. Greater shear wave velocities, larger shear moduli, and higher bulk density also characterize transgressive Lewis Shales. The most promising seal horizons are laterally extensive, silt-poor, pyritic shales occurring in the uppermost transgressive systems tract. Stacking patterns of slow and fast shale horizons can yield seismic responses comparable to those interpreted as hydrocarbon-bearing reservoirs.

Tensors and tensor algebra are presented. The concept of a tensor is defined in two ways: as something which yields a scalar from a set of vectors, and as something whose components transform a given way. The meaning and use of these definitions is expounded carefully, along with examples. The action of the metric and its inverse (index lowering and raising) is derived. The relation between geodesic coordinates and Christoffel symbols is obtained. The difference between partial differentiation and covariant differentiation is explained at length. The tensor density and Hodge dual are briefly introduced.

Abstract:

We empirically investigate the relationship between the economic growth and various monetary variables, focusing on the Greek economy. Using monthly data on the Industrial Production Index (IPI) as a proxy for economic growth, along with 10-year bond yields, 10-year bond spreads, and 3-month and 12-month interest rates, we aim to incorporate them into a multivariate GARCH-DCC econometric framework. Specifically, we examine the DCCs’ behavior during the memoranda period, pandemic period and a stable period. Our main result is that in almost all cases, the economic growth is not affected by changes in interest rates, the spread or the bond yield. Only during the pandemic period seems to be a negative relationship between the spread and bond in relation to IPI, while the 3-months rate and IPI follow a different pattern. This adds to recent doubts about the prevailing conduct of monetary policy and common theoretical models (e.g., lowering interest rates may have no effect, when trying to stimulate the economy). These results provide crucial implications for policymakers and highlight the need for some form of policy coordination among central banks.

Abstract:

In order to study the afforestation technology in rocky desertification area and provide guidance for the cultivation and management of artificial forest in the later stage, an experimental study was carried out on the artificial forest in National long term scientific research base for comprehensive control of rocky desertification in Wuling Mountain, Western Hunan Province. The experiences of afforestation, land preparation and forest management in this area were summarized. The result show that: 1. Through appropriate afforestation land preparation and forest management measures, the forest in rocky desertification area can be successfully restored. 2. Vegetation restoration in rocky desertification area has formed relatively healthy and stable multi tree species and multi-level forest communities. 3. The biological yield of each afforestation tree species was significantly different with different tree species. 4. The diversity index and evenness index of undergrowth plants in different stands were significantly different. 5. Young trees of dominant species dominated the undergrowth vegetation of different stands, and the natural regeneration of each stand has been stabilized. 6. There are some differences in soil chemical properties under different stands. There were significant differences in SOM, TN, NO3-N, NH4-N and AP contents in the soil of the eight stands.

Abstract:

The enhanced heat transfer in laminar viscoplastic, shear thinning, Herschel-Bulkley fluid flows in sinusoidal corrugated-plate channels is investigated. With uniform-temperature plate walls, periodically developed flows are considered for a wide range of flow rates (10 ≤ Reg ≤ 700) and pseudoplastic flow behavior indices (n = 0.54, 0.8, and 1.0; the latter representing a Bingham plastic). The effects of fluid yield stress are simulated for the case where τy = 1.59 N/m2, representing a 0.5% xantham gum aqueous solution. Typical velocity and temperature distributions, along with extended result

Abstract:

The aim of the paper was to develop a model determining production effects of corn irrigation depending on a drought level in the growing season.Corn is particularly useful for cultivation in the conditions of irrigation since its yield in central Poland depends significantly on rainfall distribution in growing season. Corn was grown under irrigation conditions in the years 2005-2016 in the region of central Poland, meteorological data, were gained from the research station of the UTP University of Science and Technology in Bydgoszcz. Based on the results of twelve-year effects of corn irrigat

Abstract:

We demonstrate formation of buried InGaAsP/InP quantum well waveguides by means of phosphorous ion implantation and thermal annealing during regrowth. We use absorption spectra of implanted and unimplanted regions to estimate the induced index difference, which is on the order of 1 % at 1.55 μm. Calculated mode intensities are in good agreement with the observed near field intensity patterns. With this etchless implant technique, we achieve a significant reduction in propagation loss for single-mode p-i-n waveguides relative to etched semi-insulating planar buried heterostructure waveguides fa

Abstract:

Abstract After 20 years of learnings and successful risk reduction, the pipeline industry is striving to achieve the next step change in risk performance by migrating from relative index-based risk models toward probabilistic approaches across all threats and all pipeline segments for system-wide risk assessment. While the quantification of pipeline risk can be readily supported by in-line inspection (ILI) results coupled with probabilistic limit state modeling for certain threats and pipeline segments where this information is available, where such data is lacking for other pipeline segments

Abstract:

Abstract Connectivity estimated by simply considering the relative number of nodes in fracture networks, i.e., cross-cutting (X), abutting (Y), and isolated (I), without regard to their spatial distributions, is often not a unique identifier of fracture geometry. This research proposes a modified, lacunarity based estimate of connectivity which considers both the spatial distribution of such nodes in a network and also their abundance. We compare three pairs of natural fracture maps from different sources, each pair with the same connectivity but very different visual appearances. A study of t

Abstract:

Tillage modifies soil structure, altering conditions for plant growth and transport processes through the soil. However, the resulting loose structure is unstable and susceptible to collapse due to aggregate fragmentation during wetting and drying cycles, and coalescense of moist aggregates by internal capillary forces and external compactive stresses. Presently, limited understanding of these complex processes often leads to consideration of the soil plow layer as a static porous medium. With the purpose of filling some of this knowledge gap, the objectives of this Project were to: 1) Identif

Abstract:

To enhance flame retardancy of polybenzoxazines, non-halogenated phosphorus compound has been evaluated for its potential flame retardant. In this research, the resulting flame retardanted polybenzoxazines were prepared by mixing phosphorus flame retardant with three types of arylamine-based benzoxazine resins. Their fire resistance, thermal, and mechanical properties were investigated. The weight ratios of benzoxazine resins/TPP were varied to different phosphorus content. DSC results indicated that, in the presence of TPP, the onset and maximum temperature of the exothermic peak due to the r

Abstract:

Application research of V containing high strength weathering steel in steel structure building was conducted. The research shows that: adding 0.04% V into weathering steel can lead to grain refinement of ferrite, thereby improving steel performance. Fine polygonal ferrite can make for obvious yield platform, and front cooling method can make V(C, N) precipitation in ferrite fine and dispersive to enhance dislocation pinning, which can further enhance yield effect. In this research V containing weathering steel can realize 500MPa of strength grade, 0.84 of yield ratio, 26.0% of elongation, 3.0
