Impact of Long-term and Intensive Rice Cultivation on Heavy Metal Accumulation in Soil: An Observation from Mae La River Basin, Central Thailand
Authors: Mighanetara Krongkaew , Nakpum Achira , Chalardkid Prasarn , Jaidee Rattiyaporn 
Published: June 2022

Intensive rice cultivation relies greatly on chemical fertilizers and pesticides, some of which contain heavy metals as impurities. Application of these agrochemicals can result in heavy metal accumulation in soil. This research discusses the current concentrations and migration pathways of heavy metals (Cu, Pb and Zn) in paddy soil subjected to long-term use of chemical fertilizers and pesticides. The study of soil pH and metal concentrations in 60 surface and subsurface samples from a relatively small river basin revealed that although highly varied, pH values and metal concentrations in topsoil were significantly different from values in subsurface soil. The soil pH as low as 5.4 was observed in topsoil. Although the observed levels in topsoil were in within safe limits according to the Dutch standard, they were significantly elevated above the subsurface concentrations. Evidence on the differences between their concentrations in paddy soil and river sediments suggests that considerable amount of metals in paddy fields have been transported into the river. A detailed study of input inventory, fluxes and migration pathways of these metals in the river basin can provide a better understanding of their mobility and measures that might needed to safeguard aquatic habitats, especially the well-known striped snakehead fish in Mae La River.
HIGHLIGHTS

Agrochemicals such as chemical fertilizers and pesticides contain heavy metals as impurities
Long-term and continuous use of agrochemicals in rice production has resulted in lower pH and higher heavy metal contents in topsoil
Low pH in topsoil can enhance metal mobility, suggesting that some of the heavy metals from agrochemical inputs are likely to be transported from paddy fields to their surrounding environments
This study demonstrates that the effects of agrochemical use extend beyond agricultural soil. Impact assessment of their application, thus, should cover all major compartments/systems in the basin

Authors: Fedosov Valentin Petrovich , Jameel Jaleel Sadoon , Kucheryavenko Svetlana Valentinovna 
Published: June 2022

The growth of wireless networking has contributed to the need for high-speed services and multimedia applications anywhere and at any time. OFDM WiMAX technology is now considered one of the most popular technologies capable of delivering faster implementation and lower cost than standard wired options for Broadband Wireless Connectivity in metropolitan areas. This paper proposes appropriate adaptive modulation to be used in wireless networks based on SISO and MIMO OFDM WiMAX, which allows the performance of the network to be improved in the case of non-line-of-sight communications that are typical in urban environments. The effects of several paths, signal attenuation, Doppler shift, and different mobility speeds on the performance of the system were investigated. Mathematical models analysis of adaptive modulation in SISO and MIMO systems is treated by using BER, SNR and noise components. Simulation results show that the adaptive algorithm would improve throughput. It can also be concluded that when processing signals in a receiving system under conditions of multi-path signal propagation, the use of adaptive algorithms has a positive effect on noise immunity.
HIGHLIGHTS

With the growing evolution of wireless communication technologies, there is still a need for higher data rates, increased system capacity, and improved service quality
3D OFDM-MIMO WiMAX technology is now regarded as one of the most common solutions for Broadband Wireless Connectivity in Urban Areas, capable of offering faster implementation and lower costs than standard wired options
Effective adaptive algorithm processing in 3D wireless networks based on SISO-OFDM and MIMO-OFDM WiMAX was proposed, enabling network performance to be enhanced in the case of non-LOS wireless communications, which are standard in urban conditions. On the performance of the system, signal attenuation, the effects of several paths, different mobility speeds and Doppler shift were studied
The adaptive algorithm significantly reduces the probability of error and increases the throughput. It can be concluded that the use of adaptive spatio-temporal algorithms has a positive effect on noise immunity when processing signals in the receiving system under conditions of multipath signal propagation

Published: June 2022

Gingers is widely used as the complimentary household herbal medicine since it promotes varieties of health-protective effects including anti-hyperlipidemia and anti-hypertension. This study aimed to evaluate the effect of a 30-day ginger (Zingiber officinale Roscoe, Zingiberaceae) ingestion on lipid and glucose profiles and blood pressures in hypertensive older women. The randomized double-blinded ginger consumption was designed in normotensive and hypertensive older women. Thirty-two female volunteers were randomly allocated into 4 groups of normotensives and hypertensives without and with ginger consumption, named as normotensive control (NC); normotensive with ginger consumption (NG); hypertensive control (HC) and hypertensive with ginger consumption (HG). On daily basis, the ginger-treated groups (NG and HG) ingested ginger powder at 75 mg/kgBW/day dissolved in 150 mL water after breakfast whereas control groups (NC and HC) received 150 mL water only for 30 days. Data were collected, in the morning, at pre- and post-intervention. Blood lipids, including cholesterol (chol), triglycerides (TG), high density lipoproteins (HDL), and low density lipoproteins (LDL), glucose levels and blood pressures were evaluated and compared from pre- and post-interventions. The results showed that 30-day ingestion of ginger exerted no change in normotensive groups, where alterations of blood lipid profiles were found in hypertensive groups. Both hypertensive groups (HC and HG) showed the significant reductions in SBP (p < 0.05), however, HC showed significantly increase in blood TG and LDL. HG group showed the reduction in TG and unchanged in LDL. There were no significant differences in chol, HDL, glucose levels and health-related performance from either within or between-groups comparisons (p > 0.05). This study primarily shows the minimal duration of 30-day ingestion of dissolved ginger on lowering systolic blood pressure and triglycerides but plays no roles in glycemic control in hypertensive subjects. Ginger might possibly play an important alternative role in alleviating certain health risks in the hypertensive aged females. To build up confidence on its therapeutic effect, more sample size of this local herb is needed in further investigation.
HIGHLIGHTS

Ginger is widely reported in traditional medicine to relieve symptoms and certain diseases. This herb is popularly used and easily find in Oriental countries
Ginger can be used to minimize the high prevalence of dyslipidemia and hypertension among Thai population, especially in the north and north-east regions
The minimum 30 days of ginger ingestion shows some effectiveness on blood lipids and lowers systolic blood pressure in hypertensive elderly
Ginger might possibly play additional important roles in alleviating certain health risk in the aged
