Salinization of cultivated land is increasing globally due to saline water irrigation and inherent soil salinity. A considerable variation in salinity tolerance of maize hybrids was reported widely hence selection of tolerant maize hybrids to saline water irrigation is of great significance in utilising saline water for irrigation. The present study was conducted to identify the maize hybrids tolerant to saline water irrigation under green house condition. Six maize hybrids were chosen and irrigated with saline water having varied inherent salinity levels (0.6, 3.2, 4.8, 6.7 and 8.9 dS m-1 ) and grown on Alfisol for 30 days. Plant growth attributes and gas exchange parameters were recorded on 30 day after sowing and significant variations were observed among the genotypes for different salinity levels. Increasing levels of irrigation water salinity decreased the plant growth attributes, photosynthetic activity and dry matter production of all maize hybrids. However, TNAU Maize hybrid CO 6 registered higher dry matter production and photosynthetic activity with better stress tolerance index (76.8%). All the maize hybrids tolerated the irrigation water salinity upto 3.2 dS m-1 while TNAU maize hybrid CO 6 thrives well even upto 4.8 dS m-1 , which indicated its efficiency to tolerate water salinity.

Published: May 2023

Curcuma longa L. (Zingiberaceae) rhizomes, commonly known as turmeric, is a rhizomatous, herbaceous, monocotyledonous spice as well as medicinal plant and has been traditionally used as a source of coloring matter for foods, cosmetics and textiles and as a medicinal ingredient of formulations of the Indian system of medicine for several common ailments. Turmeric is propagated through rhizomes and large quantity of rhizome is required because of the low efficiency of vegetative propagation. In addition, during storage and cultivation, rhizomes are susceptible to diseases that cause tissue senescence and degeneration. Survival percentage of plants through rhizome is low (80 per cent) in field condition. The availability of quality planting material is also scarce during the cropping season (June – September). To overcome these problems, a trial to standardize the size of the planting material and to study the effect of the transplants on growth and yield parameters was laid out with nine different treatments. Among the various treatments, single node rhizome (5g) raised in protray (1 month) and planted in the main field recorded the highest plant height (82.79 cm), more number of leaves (7.29) and number of tillers per plant (4.00). Among the nine different treatments, single node rhizome (5 g) raised in protray (1 month) and planted in the main field recorded the maximum yield of 46.20 t/ha with the highest C:B ratio of 1: 2.47 followed by mother rhizome pieces (10-15 g) raised in protray (1 month) and planted in the main field recorded the yield of 41.87 t/ha and C:B ratio of 1:2.14 as compared to control of primary full length rhizome (25-30 g) planted directly in the field (34.47 t/ha).

The research aims to improve the free poetry writing skills of class III students of MIS Darul Ihya using the Experiential Learning model. The method used in this research is Classroom Action Research (CAR), which consists of two cycles. PTK was conducted to find out how much the experiential learning method can improve class V students' free poetry writing skills. This research was conducted in class III MIS Darul Ihya, Ciomas District, Bogor Regency. The subjects of this study were 29 students of class III MIS Darul Ihya from November 2021 - January 2022. Each intervention cycle included planning, implementing, observing, and reflecting. The planning stage involves preparing teaching materials, research instruments, and observer guides. At the implementation stage, the Experiential Learning model is applied in a structured learning process following the Learning Implementation Plan (RPP), which consists of initial, core, and final activities. The results showed a significant increase in students' poetry writing skills, with an average score increasing in the classical mastery of poetry writing skills before the action. I grew to 70.05 with an excellent category (70% -79%). In cycle II, it increased to 81.05 with a perfect type (80% -89%). These findings indicate that the Experiential Learning model is a practical approach to improving students' poetry writing skills and can be recommended for classroom settings. However, further research is needed to investigate the long-term effects of this approach and its suitability for different groups of students

Authors: Dagher Khulood E.
Published: May 2023

This paper presents a new design of a nonlinear multi-input multi-output PID neural controller of the active brake steering force and the active front steering angle for a 2-DOF vehicle model based on modified Elman recurrent neural. The goal of this work is to achieve the stability and to improve the vehicle dynamic’s performance through achieving the desired yaw rate and reducing the lateral velocity of the vehicle in a minimum time period for preventing the vehicle from slipping out the road curvature by using two active control actions: the front steering angle and the brake steering force. Bacterial forging optimization algorithm is used to adjust the parameters weights of the proposed controller. Simulation results based Maltab package show the control methodology has effectiveness performance in terms of the excellent dynamic behavior of the vehicle model by minimizing the tracking error and smoothness control signals without saturation state obtained, especially when adding a bounded external disturbances to the vehicle model.

Authors: Mahmood Deyaa Mohammed Noori , Aljubury Issam M. Ali
Published: May 2023

In this work, an inventive photovoltaic evaporative cooling (PV/EC) hybrid system was constructed and experimentally investigated. The PV/EC hybrid system has the prosperous advantage of producing electrical energy and cooling the PV panel besides providing cooled-humid air. Two cooling techniques were utilized: backside evaporative cooling (case #1) and combined backside evaporative cooling with a front-side water spray technique (case #2). The water spraying on the front side of the PV panel is intermittent to minimize water and power consumption depending on the PV panel temperature. In addition, two pad thicknesses of 5 cm and 10 cm were investigated at three different water flow rates of 1, 2, and 3 lpm. In Case #1, the evaporative cooling decreased the temperature of the PV panel by about 15 ℃ related to the uncooled PV panel for both pad thicknesses. While case #2 showed a more significant temperature drop for PV panel by about 27 ℃  and 29.7 ℃ for pad thicknesses of 5 cm and 10 cm, respectively. Compared to the uncooled PV panel, the cooled panel had a distinct enhancement in performance. The efficiency of the PV panel in case #1 was augmented by 5.7% with 50 mm pad thickness and 8.4% for 100 mm pad thickness. Case #2 revealed more improvement in the efficiency by 9% for 5 cm and up to 20% for 10 cm pad thickness. The PV panel electric power was augmented by 7.3% and 13.8% for 2 and 3 lpm water flow rates, respectively. Compared to the flow rate of 1 lpm. The open voltage circuit improved by 4.1% and 9.4% for cases #1 and #2, respectively. The higher air temperature drop was about 11.4 ℃ for case #2 at 10 cm pad thickness.

Published: May 2023

The agricultural lands that depend on supplementary irrigation methods for winter wheat cultivating in wide areas of the Nineveh province are most vulnerable to climate change concerns. Due to frequent rainfall shortages and the temperature increase recently noticed and predicted by the climate scenarios. Hence important to assess the climate effect on the crop response in terms of water consumption during the periods (2021-2040) and (2041-2060) by using high-resolution data extracted from 6 global climate data GCMs under SSP5-8.5 fossil fuel emission scenarios in changing and fixed CO2 concentration. And validate the Aqua-Crop model to estimate the yield and water productivity. And gives the RRSME of 7.1- 4.1 for the calibration and verification, respectively, d and R2 equal 1, indicating good model performance. From findings, the predicted response to the temperature increase and variability in rainfall between increase and decrease represents an increase in irrigation water productivity to 28% in 2060 related to the reference period in the developed schedule under changing CO2 scenario and a reduction by 13% in the near term related to the mid-term under the fixed CO2 concentration scenario. And the simulation of yield production increased by 30 % under the scenario of changing CO2 concentration. While a slight increase of 13 % under the fixed CO2 concentration scenario. These findings help realize the future uncertain resilience of agriculture in Iraq to create efficient adaptation measures to benefit from climate change opportunities.

Published: May 2023

Introduction. Mindfulness, that is, holistic awareness and attentive presence, is becoming widespread in everyday life and clinical practice. The mindfulness approach is helpful in managing stress, somatic complaints, anxiety, depression, burnout, and traumatic experiences as well as in preventing PTSD, therefore the development and adaptation of tools to measure and assess mindfulness approach effectiveness is apparently relevant. Aim: to make known the results of the adaptation of the Ukrainian version of the short Five Facet Mindfulness Questionnaire (FFMQ - 15), developed by R. Baer et al. (called in Ukrainian PОМ-15). Methods. The adaptation of POM-15 was conducted as part of the adaptation of the full version of the Five Facet Mindfulness Questionnaire (FFMQ) - POM-39, whose five-factor scales were formed from the original long version of the POM-39 questionnaire and included observation, description, conscious action, non-judgment, and non-reactivity scales. Results. All PОМ-15 scales showed good internal consistency (with Cronbach's alpha coefficients being from 0.71 to 0.94) while the POM-15 construct reliability and the ability to differentiate the dynamics of changes as a result of therapy and training were confirmed. Conclusions. A small number of questions and short time needed to answer them as well as the ease of processing the results and their reliability make POM-15 convenient and effective in both clinical and non-clinical practice.
