Financial inclusion has generally been considered an effective mechanism to support economic growth and reduce Vietnam’s poverty for the last decade. While the importance of financial inclusion to economic growth or macroeconomic stability has been widely examined, it appears that the degree of financial inclusion across Vietnam has not attracted attention from academics and policymakers. In particular, a convergence of financial inclusion across provinces in Vietnam has never been examined. This paper is conducted to examine the static and dynamic distributions of financial inclusion across provinces in Vietnam. The latest three biennial surveys from 2014 to 2018 and a novel approach known as the dynamic kernel density function are used in this study. Our results indicate that Vietnam’s economic growth and development over the 2014–2018 period is relatively inclusive. The evidence also demonstrates that households provided with access to multiple sources of finance depend significantly on the provincial level of income. We also find that provinces located in the national key economic regions, including (i) the Northern region and (ii) the Southern region, appear to achieve a higher degree of financial inclusiveness. Our findings also confirm the catching-up from the financially disadvantaged provinces to financially advantaged provinces locating within the key economic regions. We argue that understanding the asymmetric effect of economic growth on financial inclusion will be helpful for the Vietnamese government in formulating and implementing economic policies promptly to secure the sustainable and inclusive goals of economic growth and development in the future.

This paper presents a methodology for estimating nutrient concentrations of total phosphorus (TP) and total nitrogen (TN) through the use of hydrological modeling, remote sensing datasets, and nutrient export coefficients. The strategy is applied to the Upper Tombigbee watershed, located in the northern region of the states of Mississippi and Alabama, USA. USGS GIRAS (1986), NASA MODIS MOD12Q1 (2001-2004) land use datasets, and USGS-DEM topographical datasets were used to characterize the physiography of the watershed. TN and TP concentration values estimated using the methodology were compared to values reported in the literature.

The article deals with the results of the analysis of long-term studies on the study of soil-protective, water efficiency technologies for the cultivation of crops on eroded soils. For the conditions of irrigated and erosion impacted typical loamy soils of a Chirchik-Angren valley, the law of a pliability of the typical loamy soils impacted by erosion is revealed depening on the form of furrows and the size of a jet. The optimum forms of the furrow and size of a jet are determined for condition of typical loamy soils at growing potatoes. The influence of the form of furrow on the contents of organic matter, total nitrogen, common phosphorus in a liquid and firm drain is established the losses of nutritious substances with a liquid and firm drain are revealed depending on elements of irrigation technology. The growth and development of the potatoes is studied. The economic efficiency is determined at cultivation of a potatoes on typical erosion demaged loamy soils.

Abstract Background: Vacuoles are unique compartments in plant cells. Their multiple functions require massive fluxes of molecules across their limiting membrane, the tonoplast. Transport across the tonoplast is energized by its membrane potential and the proton gradient established by two proton pumps, the vacuolar H+-ATPase (V-ATPase), and the vacuolar H+-pyrophosphatase (V-PPase), which play important roles in the growth and development of plants. However, the mechanisms by which they affect plant growth and development, in the absence of tonoplast proton pumps, remain unclear. Results: In this study, we show that the Arabidopsis thaliana double mutant, vha-a2vha-a3, which lacks two tonoplast-localized isoforms of the membrane-integral V-ATPase subunit VHA-a, is viable, but shows a phenotype of inhibited growth and leaf chlorosis. Reduced total nitrogen absorption and increased nitrate assimilation lead to the accumulation of ammonium in the shoot, which results in the growth retardation of vha-a2vha-a3. Concurrently, the distribution and concentration of cations are abnormal in plants when VHA-a2 and VHA-a3 genes are absent, which is another major growth-limiting factor. Interestingly, the growth inhibition of the vha-a2vha-a3 double mutant was alleviated and senescence delayed, while the concentration of total nitrogen increased and that of ammonium decreased, when adding additional potassium. Conclusions: Our results show that plants can be viable without VHA-a2 and VHA-a3 but are affected by multiple factors that result in growth retardation, which can be alleviated by adding additional potassium, which provides a new insight on the relationship between vacuolar H+-ATPase and potassium.

In this study, the olive pomace was considered because of its importance in the environment. So, this study carried out to estimate the total nitrogen content and the fatty acids profile of olive pomace. The olive pomace samples were collected from Irbid, Jarash, Ajloun and Mafraq during the harvesting season 2014 to study the biochemical characteristics of fatty acid composition and the total nitrogen (TN) content. The total nitrogen content was determined by standard Kjeldahl method and the fatty acid profile was detected by gas chromatography (GC). The results show that the total nitrogen content ranged from (0.39 ± 0.0) to (0.62 ± 0.02) with statistically significant difference suggesting that the composition of matrices and their percentage may be responsible for composition of amendments. The calculated total protein percentage ranged between (2.43 ± 0.00) to (3.87 ± 0.17). Also, 13 different fatty acids were quantitatively profiled and quantitated. Oleic acid (C 18:1) was found to be the highest percentage of all other fatty acids and ranged between (59.03%) and (63.81%), moreover the C 18:1/C 18:2 (oil quality) was calculated and C.V% showed variation meaning that nutritional implication could affect the oxidative stability of oils. In conclusion, OP by-product could give a sustainable and alternative-cheap source for fertilizers, pharmaceutical industries, cosmetics and other industries.

Cell and tissue interactions are a basic aspect of eukaryotic growth and development. While cell-to-cell interactions involving recognition and incompatibility have been studied extensively in animals, there is no known antigen-antibody reaction in plants and the recognition mechanisms operating in plant grafts have been virtually neglected.An ultrastructural study of the Sedum telephoides/Solanum pennellii graft was undertaken to define possible mechanisms of plant graft incompatibility. Grafts were surgically dissected from greenhouse grown plants at various times over 1-4 weeks and prepared for EM employing variations in the standard fixation and embedding procedure. Stock and scion adhere within 6 days after grafting. Following progressive cell senescence in both Sedum and Solanum, the graft interface appears as a band of 8-11 crushed cells after 2 weeks (Fig. 1, I). Trapped between the buckled cell walls are densely staining cytoplasmic remnants and residual starch grains, an initial product of wound reactions in plants.

Calcium is an important element in the growth and development of plants and one form of calcium is calcium oxalate. Calcium oxalate has been found in leaf seed, stem material plant tissue culture, fungi and lichen using one or more of the following methods—polarized light microscopy (PLM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction.Two methods are presented here for qualitatively estimating calcium oxalate in dried or fixed tobacco (Nicotiana) leaf from different stalk positions using PLM. SEM, coupled with energy dispersive x-ray spectrometry (EDS), and powder x-ray diffraction were used to verify that the crystals observed in the dried leaf with PLM were calcium oxalate.
