Full textAbstract:
Indian date palm (Phoenix sylvestris Roxb.) is one of the important nutritious, naturally abundant, potentially underutilized rain-fed fruit of the western dry tract of West Bengal available in the natural vegetation. Considering the diversity of the crop under this region, the present study aimed to study genetic diversity using multivariate analysis based on fruit physico-chemical and antioxidative properties of fifteen wild date palm accessions (P-1 to P-15) from natural vegetation of different locations from Bolpur Sriniketan Block under the Birbhum district during the year 2022 and 2023. The Indian date palm accessions exhibited wide ranges of variation in different fruit physico-chemical and antioxidative properties. The significant and high positive correlation of fruit weight with fruit size (length, diameter), pulp weight, seed weight, seed length and seed diameter were noted within Indian date palm accessions. A fairly positive correlation was observed between fruit weight, spadix girth, TSS, and total sugar. Similarly, fruit diameter was positively correlated with spadix girth, TSS, total sugar and reducing sugar. Pulp weight had a high positive correlation with TSS and total sugar. UPGMA clustering of date palm accessions has shown three major clusters. The eigenvalue and Eigenvector have exhibited five major principal components, of which the first principal component (PC1) contributed a maximum of 49.5% towards total variability. Bi-Plot also confirms the variability and the association of different characteristics within Indian date palm accessions.

Division·of Transfer of Technology, National Institute of Research on Jute & Allied Fibre Technology (ICAR), 12, Regent Park, Kolkata-700 040, India <em>E-mail :</em> nirjaft@rediffmail.com <em>Manuscript received 4 June 2009, revised 18 November 2009, accepted 26 November 2009</em> The present paper highlights the production of pulp from agro-residues by mechanical pulping for the benefit or Indian paper industry. Date-Palm leaf (DPL), a renewable agro-residue is an excellent raw material for making pulp and paper of different grades due to high alpha. cellulose (50-58%) and hemi cellulose contents (26-32%). These constituents play a stellar role In mechanical pulping I.e. In beating operation without using any chemical. Ultimate fibre length (1.25 mm to 2.50 mm) is also higher than fibres or other agro-residues, recycled cotton rag and paper. Yield and mechanical properties or the pulp of 100% DPL fibre obtained by mechanical pulping process attained higher values as compared to Its blends with recycled cotton rag. Chemo-mechanical process Is costly and not environment friendly. Moreover, yield and mechanical properties or the paper obtained in this process are poor. Hemi cellulose (more than 25%) and non-cellulosic polysaccharide which exist In cell wall of fibres contribute to efficient beating operation and fibre bonding. Hemi cellulose also contributes largely towards higher burst Index, tensile index and folding endurance to the pulp sheet specially produced without using any chemical In the entire process.

Full textAbstract:
The present study was conducted during the 2017 and 2018 seasons on date palm cv. Khalas to determine the most effective daytime to pollinate female palms to obtain optimum fruit set, yield, and best fruit characteristics. Nine, twelve-year-old date palm trees were selected for the experiment, and five spathes from each palm were chosen for pollination. These palms were pollinated at three different daytimes, i.e., at 8am (morning), 11am (late morning), and 2pm (afternoon). The experiment was laid out on Randomized Complete Block Design with three replicates for each treatment. The outcome of the study indicated significant differences among three pollination times. Date palm cv. Khalas pollinated at 11am exhibited significantly promising results regarding fruit set percentage, parthenocarpic fruit percentage, biser fruit percentage, tamar fruit percentage, bunch weight, yield per palm, fruit fresh weight, fruit length, fruit width, fruit volume, pulp weight, pulp ratio, seed ratio, pulp:seed ratio, seed weight, seed length, and fruit moisture content; however, fruit drop percentage, seed width, total soluble solids, total sugar, reducing sugar, and non-reducing sugar were not significantly affected by any pollination times. Pollination carried out at 2pm closely following to 11am pollens application time, and a number of attributes were non-significant between the two times such as fruit set percentage, parthenocarpic fruit percentage, biser fruit percentage, tamar fruit percentage, bunch weight, yield per palm, fruit volume and seed length. Early pollination time (8am) showed poor results regarding most of the attributes studied. Therefore, it is concluded that pollination should be carried out around the middle of the day when the ambient temperature is optimum, which favours pollen germination and positively influence fruit yield and quality attributes.

Full textAbstract:
This work aimed to develop an anionic cellulose nanofiber (CNF) bio-adsorbent from date palm tree waste and to investigate its removal efficiency compared to cationic methylene blue dye from contaminated water. Date palm pulp was first prepared from date palm leaves through acid hydrolysis using H2SO4, followed by hydrolysis in a basic medium using KOH, in which the process completely removed the components of hemicellulose, lignin, and silica. To obtain anionic CNF, the resulting pulp was further treated with H2SO4, followed by centrifugation. Biogel formation of the CNF suspension was promoted by sonication, where its removal efficiency of methylene blue dye was studied as a function of dye concentration, temperature, contact time, and pH value. In this work, we investigated two isotherms, i.e., Langmuir and Freundlich. The Langmuir model’s consistency with the experimental data suggests that the adsorption of methylene blue dye onto CNF is monolayer and surface-limited. The reported maximum removal efficiency of 5 mg/g at 60 °C indicates the optimal temperature for adsorption in this specific case. Additionally, a pseudo-second-order model and Elovich model were also utilized to obtain a better understanding of the adsorption mechanism, in which we found not just physical adsorption but also an indication of a chemical reaction occurring between methylene blue dye and CNF. According to the results, that pseudo-second-order model’s consistency with the experimental data suggests that the adsorption of methylene blue (MB) onto CNF is rate-limiting step involving chemisorption between the two. The study reveals that CNF adsorbents derived from renewable natural waste sources such as date palm leaves can be effective in removing cationic contaminants such as methylene blue dye.

Full textAbstract:
A wide range of variability with regard to fruit and pulp characters and taste was observed in date groves in Kutch region of Gujarat (India), which have been developed naturally from seeds. An exploration was undertaken to identify better genotypes of date palm (Phoenix dactylifera) based on their fruit quality and yield-attributing characteristics. A total of 14 fruit samples were collected and data were analysed for fruit characters. Among the different genotypes MDR2 was identified and marked superior with respect to fruiting characteristics like fruit weight (29.86 g), fruit length (53.12 mm) and quality characteristics (TSS 35.17 ºB). In India, the coastal strip of the Kutch region contains the only remaining natural date palm groves, which should be utilised and maintained to be used in future genetic improvement programmes.

Full textAbstract:
The cost of superplasticizer is increasing day by day because of high demand, scarcity of raw materials. From this, the extensive research and development works towards exploring new ingredients are required for producing sustainable and environment friendly construction materials. Date palm liquor is one such material that can be used as a chemical admixture which is obtained with Kraft process from the date-palm wood. In the present investigation black liquor is added to fresh concrete in different dosages, the concrete is then tested for rheological behavior, workability and compressive strength. From results it is shown that 1% replacement of water with black liquor increases the fresh properties of the concrete, 2% replacement of water with black pulp liquor increases the mechanical properties of the concrete and acts as a set retarder.

Full textAbstract:
This work is part of the diversification of renewable energy sources such as biomass. The present research aims to concentrate on the valorization of desert date fruits, i.e. Balanites aegyptiaca. To the best of our knowledge, this plant has never been valorized in Algeria so far. For this, it was decided to choose one part of these fruits, namely the pulp, as a substrate for anaerobic fermentation for the production of bioethanol, which was shown to have a fairly significant added value. The results of the morphological analyses of the fruits of the desert palm indicated that the pulp represents 62.71% of the entire fruit, which is quite encouraging for the completion of the present work. It should be noted that the pulp is the most important ingredient in the fermentation process to produce alcohol. Moreover, the physicochemical characteristics of the raw material showed that the pulp of the fruits of the desert palm tree are rich in sugar, with 59.68% of total sugars and 34.18% of reducing sugars. Note also that these sugars are essential elements for alcoholic fermentation. The results obtained indicated that the optimal dilution of 1/4.4 (g / mL) gives 30% bioethanol (125 g of fruit gives 30 ml of bioethanol with 92° concentration).

Full textAbstract:
The study was carried out to determine the effect of pollination methods on fruiting and yield of wet season Date palm. The experiment was set up as a complete randomized block design with three treatments, each replicated four times. The three treatments are; T1 (unpollinated), T2 (Pollination twice without protection) and T3 (Pollination twice with protection). Data were collected on fruit set, fruit drop, percentage of seedless fruits, fruit weight, pulp weight, seed weight, fruit size and bunch weight. The results indicated that pollination methods significantly affected fruit set, fruit drop, fruit weight, percentage of seedless fruits, seed weight, fruit size and bunch weight. Maximum fruit set was observed from pollination twice without protection (T2). Bunch weight was also higher in pollination without protection (T2) but it is not significantly different with T3 (pollination with protection). On the other hand, pollination with protection gives high quality fruits in terms of fruit weight, pulp weight, and less number of seedless fruits. The significant lowest yield per bunch was achieved by natural pollination (T1). The results suggested that pollination with protection of wet season inflorescences can substitute for natural pollination thus improving the quality of the wet season fruit and also reducing the need for further fruit thinning.

Full textAbstract:
This study investigates the adaptive strategies of farmers in the Todgha oasis, Morocco, as they respond to the pressing challenges of climate change. Through a mixed-methods approach, we assess the resilience mechanisms adopted to sustain agricultural production amidst increasing temperatures, unpredictable rainfall, and shifting ecological conditions. Key findings reveal that farmers rely heavily on traditional water management systems, including khettaras and modern pump-assisted irrigation, to mitigate water scarcity. Additionally, the oasis�s date palm cultivation forms a microclimate that supports a variety of crops, underscoring the importance of agroecological diversification in local resilience. Despite these efforts, rising climate impacts have affected both crop yields and livestock productivity, prompting farmers to diversify their income through off-farm activities and, in some cases, migration. This research emphasizes the critical need for policies and investment in climate-resilient infrastructure that respect traditional practices while introducing technological advancements. Supporting these strategies is essential to ensuring the sustainability and economic vitality of the Todgha oasis in an era of climate change.

Full textAbstract:
Background: Euterpe oleracea Martius, popularly known as açaí, is an abundant palm in the Amazon region. Its fruit is consumed after pulper processing, to obtain the açaí drink, whose flavonoid-rich composition draws attention to its antioxidant properties and can be used in neurodegeneration processes, slowing the progression of dementia and neurological disorders. Objectives: to list what is known at the time of this review regarding the effects of the consumption of the pulp, juice or extract of the fruits of Euterpe oleracea Mart. on the nervous system. Methods: systematic review of the literature carried out in the PubMed database using the descriptors provided by the DeCS platform: (effects) AND (euterpe oleracea) OR (açaí) AND (nervous system). A total of 33 results were obtained. Using inclusion and exclusion criteria, 24 articles were selected. Results: a positive action of this plant was observed in the modulation of free radicals and prevention of premature aging, which reveals the ability of açaí to delay the natural deterioration of cognitive function that occurs with advancing age. In addition, flavonoids act in the perivascular sheath, aiding in the growth of neuronal cells, among other things, such as the containment of neurotoxin- induced neuronal lesions and protecting from others neurotoxical compounds. Finally, the Euterpe oleracea was able to attenuate depressive symptoms and epileptic seizures. Conclusions: there is a need for further studies on this topic, in order to ratify the findings that are known to date, opening the way for new strategies to protect the nervous system’s functions.

Abstract Presented are the details for design and fabrication of a novel micro-robotic actuator in a few micron-size range. The model is in the form of contractile fiber bundles embedded in or around micron size helical compression springs. The fiber bundle is assumed to consist of a parallel array of contractile fibers made form either electrically or chemically (pH muscles) contractile ionic polymeric muscles such as polyacrylic acid plus sodium acrylate cross-linked with bisacrylamide (PAAM) or polyacrylonitrile (PAN) fibers or electrically contractile shape-memory alloy (SMA) fiber bundles. The proposed model considers the electrically or pH-induced contraction of the ionic polymeric fibers as well as resistive heating of the SMA fiber bundles in case of shape-memory alloys. A theoretical model is also presented for the dynamic modeling of such micron size robotic actuators. These robotic micro-actuators will open a new frontier to the micro-universes of biological, scientific, medical and engineering systems. On the fabrication side, helical compression springs and bellows in a few microns size range have been manufactured in our laboratories to serve as the main resilient structure for the micro-robotic actuator. In principle, any size micro-robotic linear actuator can be fabricated and tested in our laboratory. For the case of ionic polymeric gel fibers the model consists of an encapsulated hermetically sealed, helical compression spring-loaded cylindrical linear actuators containing a counterionic solution or electrolyte such as water+acetone, a cylindrical helical compression micro-spring and a collection of polymeric gel fibers (polyelectrolytes) such as polyvinyl alcohol (PVA) polyacrylic acid (PAA) or polyacrylamide. Furthermore, the helical micro-spring not only acts as a compression spring between the two hermetically sealed circular end-caps but contains snugly the polymeric gel fiber bundle and also acts as the cathode (anode) electrode -while the two actuator end-caps act as the other cathode (anode) electrodes. In this fashion, a DC electric field of a few volts per centimeter per gram of polymer gel can cause the polymer gel fiber bundle to contract (expand). This causes the compression spring to contract and pull the two end-caps closer to each other against the elastic resistance of the helical spring. By reversing the action by means of reversing the electric field polarities the gel is allowed to expand while the compression spring is also expanding and helping the linear expansion of the actuator since the polymeric gel muscle expands due to the induced alkalinity along the helical spring body. Thus, electrical control of the expansion and the contraction of the micro-robotic linear actuator is possible. A mathematical model is presented based on the proposed composite structure that takes into account all pertinent variables such as the pH of the gel fiber bundle, the pH of the surrounding medium, the hyperelastic parameters of the fiber bundle, the electrical variables of the gel, the electric field strength, the pH field strength and all pertinent dimensions followed by some numerical and experimental simulations and data. For the second model, we consider the fiber bundle of SMA to be either circumscribed inside a micron size helical compression spring with flat heads or in parallel with a number helical compression springs, end-capped by two parallel circular plates with embedded electrodes to which the ends of the SMA fibers are secured. Thus, the fibers can be electrically heated and subsequently contracted to compress the helical compression spring back and forth. Design details are first described. In essence the dynamic behavior of the actuator depends on the interaction between the current supplied to the wires and the heat transfer from the wires. Further, a mathematical model is presented to simulate the electro-thermo-mechanics of motion of such actuators. The proposed model takes into account all pertinent variables such as the strain ϵ, the temperature of the fibers T(t) as a function of time t, the ambient temperature T0, the martensite fraction ξ, the helical compression spring constant k and the overall heat transfer coefficient h. Numerical simulations are then carried out and the results are compared with experimental observations of a number of fabricated systems in a size range of a few mcrons.
