Abstract:
Date palm (Phoenix dactylifera) is a plant of the Phoenix palms whose fruit tastes sweet and can be consumed by humans. These fruit seeds usually only become a waste and never be utilised by people. The research tries to reduce the waste of date palm by using the date palm fruit seeds to replace the coffee beans. One of the processes of changing date palm fruit seeds to coffee beans is drying the seeds. Instead of using a traditional drying method, this study has designed a prototype of an Internet of Things (IoT) based monitoring system tools inside the drying room that allow humidity and temperature sensors, heater, fan, and mixer to be monitored through a smartphone in real-time. Hence, the monitoring tools inside the drying room could be controlled easily, and the data could be saved as databases in smartphone applications.

Abstract:
The earliest evidence suggesting the human utilisation of wild date palm fruits in the Near East is dated to the sixth and fifth millennia B.C. Despite the lack of archaeological data, it is commonly believed that at the end of the Late Uruk period (c. 3300–3100 B.C.) the Sumerians established the first date palm plantations. Nevertheless, this belief has never been well-proven by any scientific data, which makes this issue open to debate. This article points to the images of the date palm known from the pictographic script from Uruk as an important source of botanical data—a concept which has never been discussed in the literature—and elaborates on the phenotypic traits of the Phoenix dactylifera L. discernible there. It aims to establish the level and condition of horticultural knowledge of the cultivators of the date palm tree in the late fourth millennium B.C.Many of the botanical traits found on the date palm pictographs are noteworthy, especially where the morphology of the crown, trunk, and root zone are concerned. Most importantly, the identification of pictographs representing date palm inflorescences prompts us to the conclusion that the Sumerians discovered the dioecious nature of the Phoenix dactylifera L., selecting the staminate inflorescences to pollinate female trees by at least c. 3300 B.C. The discovery of this method of artificial fertilization was a turning point in Mesopotamian agriculture since it enabled farmers to obtain a better crop while economizing on space and labour, constituting the beginning of the date palm plantations that are still such a feature of present-day Iraq.

Abstract:
The sustainability of agricultural productivity is closely related to the optimal exploitation of natural resources, namely the efficient water resources management. The evaluation of the effectiveness of the adopted strategies and the applied practices and systems relies on a number of criteria and parameters of which water productivity indices represent the most relevant criteria. In this context, the present study aims to assess the water productivity for date palm cultivation in Tunisia based on an accurate literature review of the previously published scientific papers and reports related to the different studies carried out in these agro-oases regions of the country for the evaluation of the different indices of water productivity. This review represents the main baseline document highlighting in an exhaustive way the challenging features related to water productivity for date palm agro-systems. The outcome of this review indicates that (i) the cultivated date surface is expanding, covering more than 58.000 ha with a total production of 355.000 tons in 2021(ii) the distribution of irrigation water is variable and irregular. iii) The reported water supply for date palm range from 20,000 to 30,000 m3/ha while a number of scientific-based calculations estimate the crop water requirements for regular date palm production is between 10,000 and 18,000 m3/ha (iv) the efficiency of water conservation techniques is related to numerous in farm factors related to the old traditional surface irrigation systems, to the soil salinization, alkalization and permeability loss and to the overexploitation issues of water resources that reaching is growing and may impact the productivity of date palms and sustainability of the production system (v) the estimation of the biophysical water productivity based on the reported data reaching barely 0.66kg/m3. This overview highlights the need for an accurate evaluation of the ecological efficiency of the used management measures to a clear appreciation of the new strategies and policies to face the current constraints with regard to all different driving forces influencing water productivity both at the macro and micro scale.

Abstract:
The Date palm (Phoenix dactilifera L.) was introduced to Mexico during the Spanish colonization, but its commercial production did not develop until the second half of the past century. A literature and field research, including a trip to the oases missions and main commercial production areas, allowed us to identify the actual status for this crop in Mexico. While the date culture in the old oases is fading, in the commercial production zones it is in active development. San Luis Rio Colorado and Mexicali Valley region, comprise 97% of the commercial crop production area of the country. The main cultivar is Medjool with 94% of the growing area; actual yields are around 7.9 ton/ha. Ongoing government support and motivated growers training will lead to the application of better crop practices. It is expected to increase yields around 10 ton/ha in the next 5 years. Commercial date production is focused on exports, the internal market is growing, as well as the transformation of the product. Knowledge of the actual trends of the crop will allow to understand their historic importance and its future potential as a commodity and food. Production practices, competitive advantages and research results are presented.

Abstract:
Date palm (Phoenix dactylifera L.) is harvested for its sweet fruit mainly in the middle east and other parts of the world. It has been cultivated for several thousand years and is known to be found in Mesopotamia as well. Besides the fruit, the various parts of the tree are employed for variety of uses. The stalks of the fruit, which connect the fruit to the spikelet, are very beautiful, colourful flower like structures, which have never been described earlier. These fruit stalks could be used for decorations in houses and would then add to more economic gain to the farmer. We observed these stalks and describe here this interesting finding hitherto unreported in the world literature. DOI: http://dx.doi.org/10.3329/ijarit.v4i2.22649 Int. J. Agril. Res.

Abstract:
Oil palm smallholder farmers are among the key players and are mostly affected by social challenges to the sustainability of the oil palm sector in Malaysia. Previous literature reviews showed a lack of social studies compared to studies of the economy and environment regarding the sustainability of the oil palm industry. Therefore, a systematic literature review focused on the context of social issues and challenges reported by Malaysian oil palm smallholder farmers is presented. The PRISMA standard is applied as the foundation for the systematic literature review writing procedure. A total of 12 papers were chosen out of 340 from Web of Science, Scopus, and Google Scholar. They covered three themes, including (i) attitudes, (ii) education, and (iii) the welfare of oil palm smallholder farmers. This systematic literature review has revealed that the social issues and challenges are closely related to the respondents’ demographics, such as the study location, the level of education, and the size of the plantations managed by smallholder farmers. This paper provides an up-to-date review of the social issues and challenges that oil palm smallholder farmers in Malaysia have encountered, as well as insights into future research on critical societal issues and challenges that demand attention and efforts towards improvement.

Abstract:
Male and female infertility is a global major health problem. Approximately 15% of couples of a reproductive age are unable to achieve the desired pregnancy within 12 months, despite daily unprotected sexual intercourse, and about 10% of infertilities have no specific reason worldwide. Currently, many researchers are interested to investigate the use of natural remedies for preventive and curative purposes of infertility. This review brings together some of the data on the nutritional characteristics of the date palm and its different parts on fertility outcomes and critically evaluates the past and recent literature relevant to the consumption of date fruit against infertility-related problems. Due to its antioxidant potential, dates are considered a functional treatment for reducing the risks of infertility. In males, the date palm has a potent effect on the reproductive parameters including hormonal levels and seminal vesicle parameters as well as sperm motility, count, and viability; whereas, in females, it shows a convincing effect on reproductive parameters including oogenesis process, strengthening of oocytes, regulation of hormones, strengthening of pregnancy, reduction of the need for labor augmentation, and postpartum hemorrhage prevention.

Abstract:
In the West Bank, date palm trees have been sweeping over the Jordan Valley at an accelerating rate since the 2000s. The current scientific literature has depicted this transformation as sustainable development. This article proposes a method to harness social sciences in a meaningful manner within the interdisciplinary study of agricultural transformation. Focusing on appropriation rather than bundles of rights, within an exploration of water and land tenure, allows uncovering actors and mechanisms that remain undetected by the current scientific discourse. Date palms transform both land and water tenure. As seasonal labor replaces sharecroppers that lived on site, the livelihoods, housing security, and food security of those practicing family farming are compromised. Geospatial analysis allows a triangulation of the results produced by qualitative methods. Mapping and quantifying the spatial progression of Israeli and Palestinian date palm trees between 1999 and 2016 allows assessing the number of sharecroppers displaced by date palm trees during that period. This demonstrates a Valley Clearance is now occurring, akin to the Highland Clearances that took place in 18th century Scotland. The present transformation of agriculture in the Jordan Valley has clear social and political impacts. Donors, the Palestinian Authority, and Palestinian date palm agribusinesses refer to the Palestinian water law within the perspective of a two state solution. The Israeli Water Authority and Israeli settlers further a network of wastewater reuse which stands as the only reliable source of water for date palm cultivation in the foreseeable future and contributes to the development of a one state solution. Meanwhile, Palestinians practicing family farming rely on legal pluralism to secure their access to water.

Abstract:
Date palm (Phoenix dactylifera L.) trees are largely cultivated across the Algerian oases; they are principal sources of remuneration and the economic basis for residents of these areas. Date palm fruits are rich sources of essential nutrients, vitamins, minerals, and dietary fibers, with many potential health benefits, yet there are few studies on the chemical composition and biological properties of date palm seed oil. In this study, we present an in-depth characterization of the biochemical composition and antioxidant properties of date palm seed oil (DPSO) produced in Algeria. DPSOs of eight Algerian cultivars, Arechti, Degla-Baida, Deglet-Nour, Ghars, Haloua, Itima, Mech-Degla, and Tentbouchet, were investigated to determine their biochemical compositions and antioxidant properties. The results highlight the potential of DPSO as an alternative food and a natural resource, thanks to several important compounds having high antioxidant capacity. In particular, fatty acids and triacylglycerol (TAGs) analyses showed that oleic (42.74–50.19%), lauric (18.40–22.2%), and myristic (8.83–10.17%) were the major fatty acids, while 1-myristoyl 2-oleoyl 3-linoleoyl glycerol, 1-linolenoyl 2-oleoyl 3-linoleoyl glycerol, 1-2-linolenoyl 3-linoleoyl glycerol, and 1-linolenoyl 2-myristoyl 3-linoleoyl glycerol were the major TAGs. Biophenols and tocopherols analyses revealed the presence of important compounds, such as catechin (22.04–24.92 mg/kg), vanillin (10.67–23.98 mg/kg), and α-tocopherol (443.59 mg/kg), at high remarkable levels. Therefore, a comparison with the literature data concerning other seed oils, including olive oil, confirms that DPSO can be considered a high-quality oil, from a biochemical and biological point of view.

Abstract:
The main objective of this research was to evaluate the effects of chemical treatment and ultrasound processing (sonication) on the fiber composition and rumen degradability of date palm seeds (DPS). For this purpose, five trials were conducted. In the first trial, the effects of treating DPS with 4% sodium hydroxide (NaOH) at different temperatures (23, 50 and 100 0C) and for different times (30, 60 and 356 min) on seeds fiber content and ruminal degradability were evaluated. Relative to untreated seeds, treated seeds had lower (P<0.05) lignin and hemicellulose, and greater (P<0.05) neutral detergent fiber (NDF), acid detergent fiber (ADF) and cellulose content, particularly at high temperatures. The degradability of seeds organic matter (OM) and NDF were greater (P<0.01) in the treated (41.79 and 35.44%) than untreated seeds (24.71 and 22.77; respectively), particularly when incubated at 23 0C. Treatment time, however, had no effect (P>0.01) on seeds OM and NDF degradability.

Abstract:
Somatic embryogenesis is the mass production system of choice for date palm to increase the rates of vegetative propagation. However, the low rates of conversion to plants are common for somatic embryos. Up to 50% of plant productiqn in the Jimmah Tissue Culture Laboratory, Oman is lost during the stages of somatic embryo germination and conversion. Partial desiccation of date palm somatic embryos of the genotype Khalas Aldahra, either by dehydration for up to 4 hours or supplementation of the maturation Murashige and Skoog-based medium with sorbitol, sucrose and polyethylene glycol, increased significantly the percentage conversion to plants. In contrast, the addition of indol-3-butyric acid (IBA), a-naphthaleneacetic acid (NAA), 6-benzylaminopurine (BAP), abscisic acid (ABA), flurprimidol or activated charcoal to the germination medium did not improve the conversion of embryos to plants compared to the control. A protocol for cryopreservation of somatic embryos and embryogenic cultures of the genotype Buhabisha was developed in the current study using the vitrification method (incorporating PVS2 solution) and pretreatment with glycerol, sorbitol and dimethylsulfoxide as a cryoprotectant prior to freezing. Despite the fact that, there was a low percentage of survival of somatic embryos, the results from this study provided evidence that it is possible to cryopreserve somatic embryos and embryogenic callus of Omani date palms. A cell suspension protocol from the genotype Buhabisha was established in this study in order to utlilise more efficient micropropagation methods and to overcome the problems of the large size of somatic embryos that may lead to an efficient cryopreservation technique. NAA gave the best regeneration frequency of somatic embryos compared to 2,4-dichlorophenoxyacetic acid (2,4-D) or picloram. However, attempts to replace activated charcoal in the date palm cultures with either polyvinylpyrolidone or ascorbic acid were unsuccessful. The use of dialysis membrane to separate cell suspensions from activated charcoal was successful, but the generation of somatic embryos was low. Twenty one genotypes obtained from the Jimmah Research Station, Oman were screened and evaluated with microsatelIite markers to establish a DNA fingerprinting procedure. Simple Sequence Repeats (microsatellites) showed that date palm genotypes analysed had high genetic divergence. Importantly, somaclonal variation was not detected by DNA fingerprinting in tissue culture-derived plants of the genotype Khalas Aldahra.

Dietz, Toni Herbert. "Regulation of fruit development by pollen in the Omani date palm." Thesis, University of Nottingham, 1998. http://eprints.nottingham.ac.uk/14014/.

Full text
Abstract:
Effects of various pollen types on the fruit growth and development in two maternal cultivars of Omani Date Palm were studied in the Northern Batinah region of the Sultanate Oman. Discrete stages in the development were identified, quantified and examined with regard to important variables including fruit set, weight, size, maturity, chemical composition, appearance and yield. Procedures were developed to compare across the different maternal cultivars and temperature environments. The pollen types were distinct in their effects, particularly as regards weight, time to maturity, ripening, sugar content, appearance and yield of certain consumable fruit stages. These effects were influenced by the female type and differential fruit set. True metaxenic and xenic effects were evidenced by excluding influences of fruit set. These were on fruit fresh weight, size, maturity and ripening in cv Khasab in 1996 and 1995 and in cv Khalas in 1996. Differences in cv Khalas in 1995 were due to differences in fruit set. Pollen effects could be measured in cv Khalas throughout fruit development, while they appeared in cv Khasab only in the later stages. Khori consistently induced the highest mature fruit fresh weight (14.8 g in cv Khalas, 13.0 g in cv Khasab) compared to Bahlani (12.6 g and 12.3 g, respectively) and AI Arudsabba (12.2 9 and 11.1 g, respectively). However, differences in fruit set between pollen blocks in cv Khalas in 1995 caused the largest ripe fruit fresh weight (16.1 g) in the AI Arudsabba block compared to Bahlani (14.1 g) and Khori (13.4 g). The effect of high fruit set (initial set was 49 % with Khori and 34 % with AI Arudsabba) in masking and modifying pollen effects was evident because AI Arudsabba induced about 40 % less fruit fresh weight than Khori in the initial stages of development. The response to applications of plant growth regulators was specific to the pollen type used. GA increased, by about 100 %, fruit fresh weight in AI Arudsabba pollinated Khalas fruits but reduced it to about 50 % in Khon pollinated ones. NAA caused the abscission of all unfertilized ovaries in Khon pollinated Khalas but not in those pollinated with AI Arudsabba. In the absence of syngamy physiological rather than hereditary causes were implied. Correlations between fruit set and fruit fresh weight did not exist in the early stages suggesting that the observed pollen effects were truly metaxenic or xenic. In the later stages clear and consistent negative correlations existed for the AI Arudsabba block. Probably in the other pollen blocks some mechanism compensated this control of one variable over the other. Late correlations for the Khori block in cv Khalas suggested that high fruit fresh weight induced fruit drop. The absence of pollen effects on late correlations in cv Khasab implied a genetic cause. The strong influence of fruit set on ripening (% ripe fruits) in Khori pOllinated bunches indicated a specifically strong influence exerted by fruit set over ripening. Time to physiological maturity was affected by pollen type only in cv Khalas where AI Arudsabba and Bahlani induced earlier maturity (7 days) than Khori. Khori pollinated fruits appeared to mature later in both female cvs except cv Khalas in 1995. Bahlani induced earlier maturity in both female cvs. Regression analysis between thermal time and fruit fresh weight provided evidence for the effects specific to Khori. As Bahlani induced the same early maturity in both female cvs. Ripening was most uniform in Bahlani pollinated bunches, but faster in Khori pollinated ones. Correlations of thermal time and ripeness indicated that the temperature regime has a strong influence (r=0.99) over ripening in Bahlani pollinated bunches. Early pollen effects were probably due to physiological mechanisms, probably hormonal activity, which could be attributed to pollen type and pollination. Late effects were under the influence of male x female interactions and were thought to be genetic. Bahlani consistently induced the highest fruit fresh weight and size in the early fruit stages, but Khori in the later stages. Only in cv Khasab was Bahlani in the later stages on par with Khori in this regard. The situation was similar for fruit and seed size. Compositional differences between pollen types were not reflected in those between the ovaries one day after pollination with different male types. This largely precluded the possibility that the early growth response was directly due to the mere addition of substances contributed by the pollen grains. Preliminary investigations indicated that pollen types were a priori distinct with regard to their biochemical composition and mineral content in that AI Arudsabba and Bahlani were similar and differed from Khori. Khori's pollen grains were largest (22 mum, less than 20 mum in other types) and its pollen tube growth the most uniform (CV 56% compared to 80-110% with other types), while Bahlani had the most vigorous pollen tube growth (tube length up to 220 JlI1lI24h). Khori contained more growth promoters, possibly GA , than AI Arudsabba. Khori brought about relatively stable bunch yields in cv Khalas (11 kg in 1996, 15 kg in 1995) and large (about 4 cm long), heavy and sweet fruits, but delayed maturity of the fruits (7days in cv Khalas). AI Arudsabba produced a slightly higher cumulative yield (28 kg) of similar yield stability, but produced fruits of poor quality in regard to fruit size (about 3.5 cm in cv Khalas), fresh weight and a low total sugar content (less than 40% in Khalas, less than 50 % in Khasab). Bahlani had clear advantages, in that it induced sweet fruits, but produced the least stable yields of fruits (cv Khalas: 16 kg in 1996, 7 kg in 1995) with relatively low weight and small fruits.

Abstract:
This study aimed to address the current status of the United Arab Emirates date palms. The first chapter focused on the development of the date palm sector in the UAE. A huge increase in the date palm number was achieved in the past few decades. In the same time, there are critical issues facing this development, such as water demand, salinity, and Red Palm Weevil. The second chapter is a greenhouse experiment to test the growth of twelve date palm seeds at four NaCl levels, control, 3000, 6000, and 12000 ppm. Optimal growth found at control and 3000 ppm of NaCl. Relative growth rate (RGR), biomass, and NL decreased significantly by increasing salinity; however, no significant differences were observed in the average SGR for any cultivars. Increased NaCl leads to significant decreases in K+, Mg2+, and Ca2+ contents of plants. Na:K ratios were lower in shoots than in roots. Lulu, Fard, Khnaizi, Nabtat Safi, and Razez cultivars showed higher RGR and biomasses whereas Khnaizi, Mesally, and Safri had higher Na:K ratios than other cultivars in the control indicating higher Na+ discriminations from plant parts. The third chapter studied the vegetation change in the eastern region of the UAE. Due to shortage of fresh water resources, the vegetation of the eastern region of the UAE has experienced a series of declines resulting from salinization of groundwater. To assess these changes, field measurements combined with Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) based Soil Adjusted Vegetation Index (SAVI) were analyzed. Images from two dates, 1987 and 2000 were acquired to enable the computation of the greenness anomalies for three sites in the eastern region, Fujairah, Kalba, and Hatta. The results show an overall increase in the agricultural area, associated with a severe decrease in vegetation greenness and health conditions, particularly in the Kalba study area. The SAVI values decreased with increased soil salinity, permitting the identification of salt-affected areas. Potential areas of further research range from studying the effects of tree spacing and understory crops as immediate and potential solutions to maintain productivity and mitigate the salinity problem.

Abstract:
Date palm (Phoenix dactylifera L.) is a diploid with 18 pairs of chromosomes and an estimated genome size of 658 Mb. It is a dioecious perennial monocot, with a long generation time (a period of 4-5 years until first flowering). Date palm is one of the major fruit crops grown in the Gulf countries and particularly in the Sultanate of Oman. Approximately 250 varieties of date palm are recorded throughout the country with evaluation and characterization based on morphological and reproductive traits (e.g. fruit color, fruit shape and fruit weight). Limited molecular characterization work has been undertaken for date palm germplasm in general and Omani date palm germplasm, in particular. The principal focus of this study was to: investigate the genetic diversity of Omani date palm germplasm and compare it with 'exotic' germplasm, to differentiate between female and male plants at the molecular level and to construct an initial genetic map for date palm. Samples were taken from eight parents of the available Omani date palm controlled crosses (Khalas 4, Khalas 13 male, Um-Alsela, Khori male, Bami, Naghal, Bahlani male, and Khasab) with 90 date palms from the BC1 and F1 populations, from 194 Omani date palm accessions (151 female cultivars and 43 male trees), together with samples from Italy (Sanremo and Bordighera), USDA-ARS, France, Iraq, Libya, Sudan and Iran. The F-statistics analysis showed that the genetic variation between female and male accessions based on random markers was only 2.1 %, while within the broader group of Omani female and male accessions the molecular variation was 97%, suggesting that the Omani female and male accessions have little consistent divergence, compared to the large-scale divergence within Omani germplasm, so male palm have been derived from most genetic origins in Oman. Additionally, the Principal Coordinates Analysis (PCA) and bootstrap consensus phenetic tree showed that the Omani accessions were closely related to each other and there was no clear genetic differentiation between female and male cultivars. A high degree of genetic variation was observed between germplasm from Oman, Italy, USDA-ARS, France, Iraq, Libya, Sudan and Iran as measured by Fst (19.7 %). The PCA showed that the Europe-Africa (Italy, France, Libya and Sudan) accessions are distinguished from West-Asia (Oman, Iraq and Iran) accessions and have their own autochthonous origin, a finding which was strongly validated by bootstrap consensus tree test. A medium density genetic map in date palm was constructed using 53 individuals from BC1 and 30 individuals from F1 populations. The BC1 map consisted of 270 markers (28 SSR and 242 SNP) distributed into 29 linkage groups with total genetic length of 1.486.7 cM, while the F1 map consisted of 591 markers (21 SSR and 570 SNP) distributed into 30 linkage groups with total genetic length of 2,385.6 cM. A total of 25 combined linkage groups were possible by combining both BC1 and F1 maps through common markers. A sex-link marker locus was developed and found to predict a high level of discrimination between male and female date palms among multiple varieties distributed across the wide range of cultivation, with an accuracy of 100% in the Omani crosses, 96% in the broad Omani material and 86% in the broadest date palm germplasm. This marker was also mapped in both BC1 and F1 at 42.8 cM and 4.9 cM in linkage groups 18 and 29, respectively and on combined group 19 at 42.8cM.

Abstract:
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.

Full text
Abstract:
A chemical equilibrium model for fixed-bed gasification is developed, which allows the prediction of the syngas composition, the amount of residual coal or ash, as well as the amount of tars as a function of the gasification temperature and the elemental composition of the biomass and the tars. Moreover, the combustion heat of the gas fuel is calculated, as well as the conversion and process efficiency, in order to perform further analyses which allow the determination of energy potential for different types of biomass under several conditions of moisture and equivalence ratio of gasifying agent. Performance of the proposed model is compared to prediction of some models which were found to be relevant in the literature review. An assessment to the model is also carried out. For this purpose, a case-study is performed for African palm (Elaeis guineensis) shells using a commercial gasifier. Experimental data obtained from the biomass used in the case-study are used to feed the model and perform the assessment. Actual results and model predictions (results) are compared varying the equivalent relation between 0.05 and 0.65, and the moisture content form biomass between 0 and 20%. This case is proposed as a benchmark case for further applications.

Abstract:
There is currently a sustained interest in biofuels as they represent a potential alternative to petroleum derived fuels. Biofuels are likely to help decrease greenhouse gases emissions and the dependence on oil resources. Biodiesels are Fatty Acid Methyl Esters (FAMEs) that are mainly derived from vegetable oils; their compositions depend from the parent vegetables: rapeseed (“RME”), soybean (“SME”), sunflower, palm etc. A fraction of biodiesel has also an animal origin (“tallow”). A key factor for the use of biofuels in gas turbines is their Emissions Indices (NOx, CO, VOC, PM) in comparison with those of conventional “petroleum gasoils”. While biodiesels reduce carbon-containing pollutants, experimental data from diesel engines show a slight increase in NOx. The literature relating to gas turbines is very scarce. Two recent, independent field tests carried out in Europe (RME) and in the USA (SME) showed slightly lower NOx while a lab test on a microturbine showed the opposite effect. To clarify the NOx index of biodiesels in gas turbines, a study has been undertaken, taking gasoil and natural gas (NG) as reference fuels. In this study, a calculation of the flame temperature developed by the 3 classes of fuels has been performed and the effect of their respective compositions has been investigated. The five FAMEs studied were RME, SME and methyl esters of sunflower, palm and tallow; these are representative of most widespread vegetable and animal oil bases worldwide. The software THERGAS has been used to calculate the enthalpy and free energy properties of the fuels and GASEQ for the flame temperature (Tf), acknowledging the fact that “thermal NOx” represents the predominant form of NOx in gas turbines. To complete the approach to structural effects, we have modeled two NG compositions (rich and weak gas) and three types of gasoil using variable blends of eleven linear/branched/cyclic molecules. The results are consistent with the two recent field tests and show that the FAMEs lie close to petroleum gasoils and higher than NG in terms of NOx emission. The composition of the biodiesel and regular diesel fuel influences their combustion heat: methyl esters with double bonds see a slight increase of their Tf and their NOx index while that of gasoil is sensitive to the aromatic content.

Abstract:
Date palm (Phoenix dactylifera L.) is the major fruit tree grown in arid areas in the Middle East and North Africa. In the last century, dates were introduced to new regions including the USA. Date palms are traditionally propagated through offshoots. Expansion of modern date palm groves led to the development of Tissue Culture propagation methods that generate a large number of homogenous plants, have no seasonal effect on plant source and provide tools to fight the expansion of date pests and diseases. The disadvantage of this procedure is the occurrence of off-type trees which differ from the original cultivar. In the present project we focused on two of the most common date palm off-types: (1) trees with reduced fruit setting, in which most of the flowers turn into three-carpel parthenocarpic fruits. In a severe form, multi-carpel flowers and fruitlets (with up to six or eight carpels instead of the normal three-carpel flowers) are also formed. (2) dwarf trees, having fewer and shorter leaves, very short trunk and are not bearing fruits at their expected age, compared to the normal trees. Similar off-types occur in other crop species propagated by tissue culture, like banana (mainly dwarf plants) or oil palm (with a common 'Mantled' phenotype with reduced fruit setting and occurrence of supernumerary carpels). Some off-types can only be detected several years after planting in the fields. Therefore, efficient methods for prevention of the generation of off-types, as well as methods for their detection and early removal, are required for date palms, as well as for other tissue culture propagated crops. This research is aimed at the understanding of the mechanisms by which off-types are generated, and developing markers for their early identification. Several molecular and genomic approaches were applied. Using Methylation Sensitive AFLP and bisulfite sequencing, we detected changes in DNA methylation patterns occurring in off-types. We isolated and compared the sequence and expression of candidate genes, genes related to vegetative growth and dwarfism and genes related to flower development. While no sequence variation were detected, changes in gene expression, associated with the severity of the "fruit set" phenotype were detected in two genes - PdDEF (Ortholog of rice SPW1, and AP3 B type MADS box gene), and PdDIF (a defensin gene, highly homologous to the oil palm gene EGAD). We applied transcriptomic analyses, using high throughput sequencing, to identify genes differentially expressed in the "palm heart" (the apical meristem and the region of embryonic leaves) of dwarf vs. normal trees. Among the differentially expressed genes we identified genes related to hormonal biosynthesis, perception and regulation, genes related to cell expansion, and genes related to DNA methylation. Using Representation Difference Analyses, we detected changes in the genomes of off-type trees, mainly chloroplast-derived sequences that were incorporated in the nuclear genome and sequences of transposable elements. Sequences previously identified as differing between normal and off-type trees of oil palms or banana, successfully identified variation among date palm off-types, suggesting that these represent highly labile regions of monocot genomes. The data indicate that the date palm genome, similarly to genomes of other monocot crops as oil palm and banana, is quite unstable when cells pass through a cycle of tissue culture and regeneration. Changes in DNA sequences, translocation of DNA fragments and alteration of methylation patterns occur. Consequently, patterns of gene expression are changed, resulting in abnormal phenotypes. The data can be useful for future development of tools for early identification of off-type as well as for better understanding the phenomenon of somaclonal variation during propagation in vitro.

Full text
Abstract:
Oil palm (Elaeis guineensis) is of strategic importance to the Ghanaian economy. It is the second most important industrial crop after cocoa and is used widely in local food preparation as well as in industrial processing. In spite of its importance, however, oil palm has consistently underperformed since the early twentieth century. This paper conducts a value chain analysis of the crop, foregrounding the political economy factors that shape the performance of the sector. It draws on a combination of in-depth interviews conducted in March 2020 with a variety of value chain actors and a review of the secondary literature. Additionally, between late May and early June 2020, twelve further interviews were conducted as part of a rapid market survey to assess the impact of the COVID-19 pandemic on the value chain.

Abstract:
Authentication methods based on human traits, including fingerprint, face, iris, and palm print, have developed significantly, and currently they are mature enough to be reliably considered for human identification purposes. Recently, as a new research area, a few methods based on non-facial skin features such as vein patterns have been developed. This literature review paper explores some key biometric systems such as face recognition, iris recognition, fingerprint, and palm print, and discusses their respective advantages and disadvantages; then by providing a comprehensive analysis of these traits, and their applications, vein pattern recognition is reviewed.

Full text
Abstract:
As the second most important industrial crop in Ghana, oil palm holds the potential of improving farmers’ livelihoods and alleviating rural poverty. For smallholder farmers, collective action through farmer-based organisations (FBOs) could provide a pathway to inclusive participation in agricultural commercialisation. There is ample evidence in the literature that collective action can help smallholders gain access to credit, improved inputs, or even networks of social support. Thus, collective action is widely recognised as a viable pathway out of poverty for the agrarian poor. However, our findings show that FBOs were either weak or non-existent. Indeed, we find that economic relations between farmers tend to be more individualised than one would expect to find in rural communities. This paper presents these findings, and explores why this is the case.

The relationship between armed groups and mining is complex. Reports of armed interference in mining are provided by the United Nations (UN) Group of Experts on the Democratic Republic of Congo (DRC) and reported in the literature, including which groups have been found to operate in which areas. Academic analysis finds the presence of industrial mining companies reinforces the power of politico-military entrepreneurs. This rapid review found a relatively large body of literature on the issue of armed groups and mining. Articles are a mix of academic literature and agency report prioritised based on relevance to the question, date, and location. The complexity of the issue requires broader investigation than is possible within the scope of a K4D helpdesk.

While useful in their own right, scoping reviews may also be helpful precursors to systematic reviews and can be used to confirm the relevance of inclusion criteria and potential questions. (Munn et al. BMC Medical Research Methodology (2018) 18:143) The aim of this review is to scope the empirical-based and peer-reviewed European OS research literature and map identified research methods, theories or theoretical concepts, and target groups to obtain a status quo overview of OS research undertaken in Europe between 2015 and 2020. Research questions: • What recent development is seen when mapping the empirical-based and peer-reviewed European OS research literature in accordance with publication volume, publication date and geographical context? • What characterizes the identified research methods, theories or theoretical concepts, and target groups applied in the peer-reviewed OS research literature?
