Published: October 2020

Through the practice of irrigation, surface water reservoirs (SWRs) contribute to the socio-economic development and food production activities of populations in Sub-Saharan Africa (SSA). However, they tend to dry up prematurely. One solution to circumvent these irrigation water shortages is to ensure their conjunctive use with groundwater. The objective of this study is to better understand the contribution of SWRs to groundwater recharge and to determine if groundwater may be considered as a complementary local resource for irrigation. The study was carried out on two watersheds in Burkina Faso, Kierma and Mogtedo. The spatiotemporal analysis of piezometric and SWRs level records coupled with physico-chemical analyses of water was used to characterize exchanges between SWRs and groundwater. The regional groundwater recharge at the scale of the watersheds was assessed. At the SWRs scale, a water balance methodology was developed and used to estimate focused recharge. The results show that SWRs interact almost continuously with groundwater and contribute focused recharge. The magnitude of this recharge is a function of the geological context and the sediment texture of the SWRs. It is estimated at 5 mm/day in Kierma and 4 mm/day in Mogtédo. These values are higher than the natural recharge estimated at 0.2 mm/day in Kierma and 0.1 mm/day in Mogtédo. Additionally, the values of hydraulic conductivity are between 0.01 and 2 m/day in Kierma and between 1 × 10−4 and 0.2 m/day in Mogtédo. These conductivities could allow pumping in large-diameter hand-dug wells with a significant yield between 0.5 and 120 m3/day in Kierma and between 0 and 10 m3/day in Mogtédo to palliate the early drying up of the SWRs.

Published: October 2020

Climate change impacts on social and economic assets and activities are expected to be devastating. What is as important as the analysis of climate change triggered events is the analysis of a combination of climate change related events and other natural hazards not related to climate change. Given this observation, the purpose of this study is to present a coastal risk analysis for potential earthquake triggered tsunamis (ETTs) coupled with the sea level rise (SLR) in the Eastern Mediterranean Sea. For this purpose, extensive stochastic analysis of ETTs, which are not related to climate change, are conducted considering the effects of climate change related SLR projections for this century. For the combined analysis, economic and social risks are evaluated for two regions in the Eastern Mediterranean Coastline, namely the Fethiye City Center at the Turkish Coastline and the Cairo Agricultural Area near Egypt. It is observed that ignoring SLR will hinder realistic evaluation of ETT risks in the region. Moreover, spatial evaluations of economic and social risks are necessary since topography and proximity to the earthquake zones affect inundation levels due to ETTs in the presence of SLR.

Authors: Zhang Yuekan , Yang Meng , Liu Peikun
Published: October 2020

Traditional hydrocyclones can be used for the concentration of sewage-containing sediments, but the low underflow concentration and the high content of fine particles result in a large subsequent dehydration workload. This study aimed to investigate the effect of columnar hydrocyclone column height on separation performance and the change in the internal flow field after the underflow orifice of the hydrocyclone was closed, so as to provide a theoretical basis for improving the ability to treat the sewage of the hydrocyclone. Numerical simulation was used to examine the change in the separation performance of the hydrocyclone and the effect of column height on the separation performance of the hydrocyclone in the case of the closed underflow orifice during intermittent discharging. The results indicate that a proper increase in column height was beneficial to improve the separation performance of the hydrocyclone. With the increase in the closing time of the underflow orifice, the particle content at the bottom of the hydrocyclone increased significantly. The experiment proves the feasibility of the intermittent discharge method in practice, and this working method can effectively increase the underflow concentration.
Drought in the Upper Hron Region (Slovakia) between the Years 1984–2014
Authors: Vido Jaroslav , Nalevanková Paulína
Published: October 2020

Climate change causes an increase in the frequency and severity of weather extremes. One of the most relevant severe and damaging phenomena in Europe is drought. However, a difference in the spatial frequency of the occurrence and drought trends is evident between southern and northern Europe. Central Europe and particularly the West Carpathian region form a transitional zone, and drought patterns are complicated because of the geomorphologically complicated landscape. Since almost half of the Slovak state territory is represented by such natural landscape, it is necessary to investigate regional drought specifics. Therefore, we decided to analyze drought occurrence and trends using the SPI (Standardised Precipitation Index) and the SPEI (Standardised Precipitation Evapotranspiration Index) at available climatological stations of the Slovak Hydrometeorological Institute (SHMI) in the upper Hron region within the 1984–2014 period. We found that (1) drought incidence decreased with increasing altitude, (2) increasing air temperature increased the difference in drought trends between lowlands and mountains during the studied period, and (3) abrupt changes in time series of drought indices, that could indicate some signals of changing atmospheric circulation patterns, were not revealed. Finally, we constructed a simplified map of drought risk as an explanation resource for local decision-makers.

Published: October 2020

To improve the understanding of the seasonal evolution of the mass and heat budget of ice-covered lakes in the cold and arid climate zone, in-situ observations were collected during two winters (2016–2017 and 2017–2018) in Lake Wuliangsuhai, Inner Mongolia, China. The mean snow thickness was 5.2 and 1.6 cm in these winters, due to low winter precipitation. The mean ice thickness was 50.9 and 36.1 cm, and the ice growth rate was 3.6 and 2.1 mm day−1 at the lower boundary of ice. Analyses of mass and heat balance data from two winters revealed that the surface heat budget was governed by solar radiation and terrestrial radiation. The net heat flux loss of the ice was 9–22 W m−2, affected by the snow and ice thickness. Compared to boreal lakes, Lake Wuliangsuhai received more solar radiation and heat flux from the water. The ice temperature had a strong diurnal variation, which was produced by the diurnal cycles of solar radiation, and air and water temperatures. These results expand our knowledge of the evolution of mass and heat balance in temperate lakes of mid-latitude arid areas.
The Initial Deposition Behavior of Silica Colloid and Amino-Modified Silica Colloid in Unsaturated Sand Columns
Authors: Fujita Yosuke , Kobayashi Motoyoshi
Published: October 2020

Colloid transport experiments focusing on the initial deposition stage in water-unsaturated sand columns were conducted. To examine the effect of electrostatic interaction in the unsaturated condition, negatively and positively charged silica colloids were used for column transport experiments under different salt concentrations. The results of the column experiments were analyzed based on the colloid filtration theory and the deposition rate constants, and the single collector efficiency was calculated. The deposition rate constants of both negatively and positively charged silica in a water-unsaturated condition are larger than those in a water-saturated condition at an equivalent salt concentration, because the interface between air and water acts as an additional deposition site. The negatively charged silica shows the salt concentration, above which electric double layer (EDL) repulsion can be neglected, and the salt concentration is called critical deposition concentration (CDC). The CDCs were almost the same values in water-saturated as well as unsaturated conditions. The deposition rate constants of the positively charged silica were slightly increased at 0.05 mM due to the EDL attractive forces in the saturated condition. However, we could not see the significant effects of the EDL attractive force in the unsaturated condition in this study. Also, the present results demonstrated that a correlation equation for calculating collector efficiency can be applied to the non-spherical collector particles.
Quantitative Analysis of the Influencing Factors and Their Interactions in Runoff Generation in a Karst Basin of Southwestern China
Authors: Hou Wenjuan , Gao Jiangbo , Wu Shaohong
Published: October 2020

The unique geological conditions of karst regions create highly heterogeneous habitat characteristics, and the addition of human disturbance results in rocky desertification. Water and soil loss are the core questions, and moreover, runoff is the key factor in this process. To further investigate these problems, a typical karst peak cluster depression in southwestern China was selected for this study. Based on the optimal simulation of the runoff yield and flow in this area, the factor detectors and interaction detectors in the geographical detector method were used to quantitatively analyze the factors influencing runoff and their interactions for different geomorphic types. The results show that: (1) the three main factors influencing the total river runoff, surface runoff, and groundwater are landscape fragmentation, land use type, and precipitation, but the ranking of these main influencing factors in each geomorphic type region exists different; (2) the dominant factor in the relatively higher elevation regions is precipitation; (3) the interaction detector results reveal that the interactions between factors enhance the overall influence of a single factor on the runoff generation in all of the geomorphic type regions, including two interaction types of nonlinear enhancement and bifactor enhancement; and (4) the interactions between the factors in the middle elevation plain, middle elevation terrace, and middle relief mountain regions are stronger than those in the middle elevation hill and small relief mountain regions. Quantitative analysis of the factors influencing runoff in karst areas cannot only promote optimization of the water and soil services, but it also provides a scientific basis for improving the comprehensive treatment of rocky desertification.

Published: October 2020

In this study, the reduction of the pesticide simazine at an initial concentration of 0.7 mg L−1 in water has been investigated using two different technologies: adsorption with powdered and granulated activated carbon, advanced oxidation processes with ozone and finally, the combination of both technologies. The results obtained for a carbon dose of 16 mg L−1 show that powdered activated carbon, with contact times of 60 min, obtained 81% of reduction and in 24 h 92%, while granulated activated carbon at 60 min obtained a reduction of 2%, rising to 34% after 24 h of contact time. Therefore, powdered activated carbon achieves better reductions compared to granulated; when ozone was applied at a dose of 19.7 mg L−1, with a reaction time of 18 min, a reduction of 93% was obtained, achieving a better reduction in less time than with adsorption treatments; however, during oxidation, by-products of simazine were produced. In the combined treatments, with the same doses of carbon and ozone mentioned above, the treatment that starts with ozone followed by activated carbon powder is recommended due to the adsorption in the last phase reaching a 90% reduction of the simazine and its by-products in 38 min of time.

Published: October 2020

Many calibration techniques have been developed for the Soil and Water Assessment Tool (SWAT). Among them, the SWAT calibration and uncertainty program (SWAT-CUP) with sequential uncertainty fitting 2 (SUFI-2) algorithm is widely used and several objective functions have been implemented in its calibration process. In this study, eight different objective functions were used in a calibration of stream flow of the Pursat River Basin of Cambodia, a tropical monsoon and forested watershed, to examine their influences on the calibration results, parameter optimizations, and water resources estimations. As results, many objective functions performed better than satisfactory in calibrating the SWAT model. However, different objective functions defined different fitted values and sensitivity rank of the calibrated parameters, except Nash–Sutcliffe efficiency (NSE) and ratio of standard deviation of observations to root mean square error (RSR) which are equivalent and produced quite identical simulation results including parameter sensitivity and fitted parameter values, leading to the same water balance components and water yields estimations. As they generated reasonable fitted parameter values, either NSE or RSR gave better estimation results of annual average water yield and other water balance components such as annual average evapotranspiration, groundwater flow, surface runoff, and lateral flow according to the characteristics of the river basin and the results and data of previous studies. Moreover, either of them was also better in calibrating base flow, falling limb, and overall the entire flow phases of the hydrograph in this area.
Effects of Pressure and Nozzle Size on the Spray Characteristics of Low-Pressure Rotating Sprinklers
Authors: Chen Rui , Li Hong , Wang Jian , Guo Xin
Published: October 2020

Using low-pressure sprinklers in agricultural irrigation has become an alternative way of reducing water and energy stress. To determine the applicability of the low-pressure rotating sprinkler, an experiment was conducted to evaluate the effects of working pressure and nozzle size on sprinkler rotation speed, application rate, droplet size, droplet velocity, droplet trajectory angle, and kinetic energy distribution. The results showed that the mean droplet diameter increased exponentially along with the increase in distance from the sprinkler, and a logarithmic relation was derived between droplet diameter and droplet velocity. Due to the low breakup degree of the jet under the lowest working pressure of 100 kPa, the peak values of specific power and application rate were high, which reached 0.09 W m−2 and 11.35 mm h−1, and were 3.1–5.4 times and 2.5–3.1 times those of other working conditions. Meanwhile, the peak specific power of the biggest nozzle (diameter = 5.2 mm) was 2.4–2.8 times that of smaller nozzles. With an increase in working pressure, the sprinkler time per rotation decreased and the distributions of kinetic energy and water became more uniform. Thus, it is not recommended to equip the sprinkler with a large nozzle under low working pressure.

The purpose of this study was to determine the understanding of tax regulations, the awareness of paying taxes and the level of income of MSMEs that affect the compliance of MSME taxpayers. This type of quantitative research and data sources were obtained from questionnaires that were distributed directly to MSME owners. Multiple linear regression was used as a method of data analysis. The results of data analysis concluded that the understanding of tax regulations and the level of income of MSMEs had an effect on the compliance of MSME taxpayers. The awareness of paying taxes does not affect the compliance of MSME taxpayers. This may imply that even though business actors are willing to pay taxes, they have not been able to improve their tax compliance.

Abstrak

Tujuan dari penelitian ini adalah untuk mengetahui pemahaman peraturan perpajakan, kesadaran membayar pajak dan tingkat pendapatan UMKM berpengaruh terhadap kepatuhan wajib pajak UMKM. Jenis penelitian kuantitatif dan sumber data diperoleh dari kuesioner yang dibagikan langsung kepada pemilik UMKM. Regresi linier berganda digunakan sebagai metode analisis data. Hasil analisis data disimpulkan bahwa pemahaman peraturan perpajakan dan tingkat pendapatan UMKM berpengaruh terhadap kepatuhan wajib pajak UMKM. Untuk kesadaran membayar pajak tidak berpengaruh terhadap kepatuhan wajib pajak UMKM. Hal ini dapat diartikan bahwa meskipun pelaku usaha mau membayar pajak namun belum dapat meningkatkan kepatuhan perpajakannya.

Published: October 2020

This paper aims to provide curriculum suggestions and forms of learning that are able to make every human being the result of learning become a manifestation of the Universal Welfare architecture. From criticizing the economic, management, and Islamic / Sharia accounting curricula, it can be seen that it is not enough just to "stick" the sharia label to the course. Subjects must contain the basic bases of universal welfare, such as courses on Critical Reading of the World, Islamic Epistemology, and Civilization. The learning strategies offered are: Critical and Spiritual Dialogue to Awaken the Meaning of Substances; b) Community Engagement; c) Concrete Projects of Cooperation with Various Interests; d) Use of Information Technology with Morals.

Abstrak

Tulisan ini bertujuan untuk memberikan usulan kurikulum dan bentuk pembelajaran yang mampu membuat setiap manusia hasil pembelajaran menjadi pewujud arsitektur Kesejahteraan Semesta. Dari menyampaikan kritik atas kurikulum ekonomi, manajemen, akuntansi Islam/Syariah, dapat diketahui bahwa tidaklah cukup sekadar “menempelkan” label syariah pada mata kuliah. Mata kuliah harus memuat basis dasar Kesejahteraan semesta, seperti mata kuliah Pembacaan Kritis Terhadap Dunia, Epistemologi Islam, dan Peradaban. Strategi pembelajaran yang ditawarkan yaitu: Dialog Kritis dan Spiritual untuk Menyadarkan Makna Substansi; b) Pelibatan dengan Masyarakat; c) Proyek Konkret Kerja Sama dengan Berbagai Kepentingan; d) Pemanfaatan Teknologi Informasi dengan Akhlak.
APTITUD COMBINATORIA DEL RENDIMIENTO DE ANTOCIANINAS Y DE CARACTERÍSTICAS AGRONÓMICAS EN POBLACIONES NATIVAS DE MAÍZ PIGMENTADO

Los granos de maíz (Zea mays L.) rojos, azules y púrpuras contienen antocianinas de importancia en la prevención de enfermedades humanas. La selección por color de grano se considera relevante en la actualidad. Para lograr la definición de metodologías eficientes de selección conviene aplicar diseños genéticos que permitan analizar la contribución genética en la variación cuantitativa de las características de interés. Se usó un diseño genético para estimar los efectos de aptitud combinatoria general (ACG) y específica (ACE), maternos (EM) y recíprocos (ER) de la concentración de antocianinas por unidad de peso de grano (CAkg) y el rendimiento de antocianinas por hectárea (RAha). Se estableció un experimento de cruzas dialélicas entre cinco poblaciones nativas contrastantes en su color de grano, donde se midieron variables agronómicas. También se obtuvo la semilla F2, con polinización controlada, para medir la concentración de antocianinas en el grano completo. Con base en los dos experimentos se calculó el rendimien-to de antocianinas por planta (RApta), el RAha y la heterosis. Hubo semejanza entre progenitores en las variables agronómicas pero difirieron en su capacidad de acumular antocianinas. Los efectos de ACG fueron superiores en la mayoría de las características agronó-micas, con respecto a los de ACE. En RApta hubo efectos significativos de ACG, ACE y ER, y fue la población Rojo-1 la de mayor ACG. Hubo heterosis entre cruzas para CAkg, siendo las mejores Rojo-1 x Rojo-2, Rojo-1 x Azul-1 y Rojo-1 x Azul-2; y para RAha las mejores cruzas fueron Rojo-1 x Rojo-2 y Rojo-1 x Azul-2.
TRANSFERENCIA DEL GEN Lr14a DE TRIGOS HARINEROS A TRIGOS CRISTALINOS Y EXPRESIÓN DE LA RESISTENCIA A ROYA DE LA HOJA

El origen del gen de resistencia Lr14a a roya de la hoja causada por Puccinia triticina E. es el trigo tetraploide ‘Yaroslav emmer’ (Triticum dicoccum L.). En México, todas las razas de trigo harinero (T. aestivum) importantes son virulentas a este gen. Sin embargo, las razas que atacan trigos cristalinos o duros son avirulentas a Lr14a. Se ha determinado la presencia de Lr14a en trigo harinero y en especies silvestres tetraploides, pero no en trigos cristalinos o trigos duros (T. turgidum spp durum). El gen Lr14a se transfirió a la variedad cristalina ‘Altar C84’ a partir de la cruza de ésta con la línea monogénica de trigo harinero ‘RL6013’ (Selkirk/6*Thatcher) y una retrocruza hacia ‘Altar C84’. Para determinar la genética de la resistencia de la variedad ‘Jupare C2001’, resistente a la raza de roya de la hoja que venció la resistencia de ‘Altar C84’, y determinar si ‘Jupare C2001’ posee Lr14a, se cruzó con ‘Altar C84’ y con ‘Altar C84’+Lr14a. La respuesta del gen de resistencia a roya de la hoja Lr14a a la infección en plántula a las razas BBG/BN y BCG/BN que son virulentas en ‘Altar C84’, es de heterogénea con uredinios grandes (X a X+) en la escala de 0-4, tanto en trigos harineros como en ‘Altar C84’, mientras que confiere casi inmunidad en planta adulta a estas mismas razas. La cruza de ‘Jupare C2001’ con ‘Altar C84’+Lr14a indicó que ‘Jupare C2001’ no posee Lr14a, y que la resistencia de esta última se basa en dos genes complementarios dominantes. Para el funcionamiento efectivo de la resistencia que el gen Lr14a confiere en trigos cristalinos en respuesta a las razas de roya de la hoja que preferentemente atacan trigos harineros, es necesaria la presencia del gen de ‘Altar C84’.

El trabajo se llevó a cabo en Gómez Palacio, Durango, México, con el objetivo de determinar la función de producción que relacione el rendimiento de canola (Brassica napus L.) con el nivel de hume-dad del suelo. Se aplicaron siete tratamientos de riego, consistentes de seis diferentes niveles de abatimiento de la humedad aprovechable residual del suelo al momento de regar (0, 12, 24, 36, 48 y 60 %), y un tratamiento adicional con sólo el riego de presiembra. Se utilizó un diseño experimental de bloques completos al azar con cuatro repeticiones. Las variables evaluadas fueron rendimiento de grano, eficiencia del uso de agua y lámina de agua consumida. Según la función de producción obtenida, es posible lograr un rendimiento de grano de 3.1 t ha-1, con una lámina de agua de 48 cm distribuida con riegos aplicados cuando la humedad aprovechable residual en el suelo baja a 35 %, equivalente a una tensión de humedad de -0.74 MPa.
