Authors: Luo Lei , Zheng Zhenhua , Luo Jing , Jia Yuqiu , Zhang Qi , Wu Chun , Zhang Yifeng , Sun Jia
Published: September 2020

The important role of the entity economy, especially manufacturing, has been further highlighted after the outbreak of COVID-19. This study fills a research gap on manufacturing in the Wuhan Metropolitan Area by analyzing the spatio-temporal evolution patterns and characteristics of manufacturing, exploring the major location factors causing spatial reconstruction and comparing the effect intensities of the different factors in the manufacturing sector. From 2003 to 2018, the process of industrial suburbanization in the Wuhan Metropolitan Area continued to strengthen and currently the overall spatial pattern of manufacturing in the Wuhan Metropolitan Area is characterized by spreading in metropolitan areas and aggregation in industrial parks. The results of a spatial metering model showed that the dominant factors affecting the layout of manufacturing included innovation and technical service platforms, industrial parks, the number of large enterprises, living convenience, and air quality. However, the effect intensity of the different location factors varied among industries. The findings may help the government to understand the characteristics of agglomeration and spreading in the manufacturing industry and, in accordance with the dominant factors affecting the location of this industry, rationally develop ideas for adjusting the industrial layout in the post-coronavirus age.

Published: September 2020

As the demand for biofuels increases globally, microalgae offer a viable biomass feedstock to produce biofuel. With abundant sources of biomass in rural communities, these materials could be converted to biodiesel. Efforts are being done in order to pursue commercialization. However, its main usage is for other applications such as pharmaceutical, nutraceutical, and aquaculture, which has a high return of investment. In the last 5 decades of algal research, cultivation to genetically engineered algae have been pursued in order to push algal biofuel commercialization. This will be beneficial to society, especially if coupled with a good government policy of algal biofuels and other by-products. Algal technology is a disruptive but complementary technology that will provide sustainability with regard to the world’s current issues. Commercialization of algal fuel is still a bottleneck and a challenge. Having a large production is technical feasible, but it is not economical as of now. Efforts for the cultivation and production of bio-oil are still ongoing and will continue to develop over time. The life cycle assessment methodology allows for a sustainable evaluation of the production of microalgae biomass to biodiesel.

Authors: Huo Jinwei , Zhang Xinhuan , Zhang Zhiping , Chen Yaning
Published: September 2020

Against the background of China’s relaxation of family planning standards, this thesis analyzed the demographic trends in ethnic minority areas and their impacts on regional development under China’s adjustment of its population strategy. By setting up different fertility scenarios, the population forecasting software (PADIS-INT) was applied to forecast the population scale and structure of the Hotan region. This thesis analyzed the impacts of population growth on regional sustainable development from the perspectives of employment, economic development, and resource carrying capacity to provide references for the formulation and implementation of population and economic development policies in minority areas, to alleviate the contradiction between the human and environment. The results showed that the Hotan region would maintain a relatively fast population growth rate for a long period; by 2050, its population would skew younger when compared to China’s general statistics. However, due to the lagging economic development and the constraints to resources and the environment, unemployment would become the most severe problem hampering regional development. While developing its local economy, the Hotan region needs to better promote the interregional migration of the labor force.
Peripheralization Risk Mitigation: A Decision Support Model to Evaluate Urban Regeneration Programs Effectiveness
Authors: Gerundo Roberto , Nesticò Antonio , Marra Alessandra , Carotenuto Maria
Published: September 2020

The term peripheralization indicates a process that can generate social, physical, and environmental degradation in urban areas. In the light of the new urban geography and the socio-economic trends taking place globally, there is a risk that the typical decay of a peripheral condition may affect city in their entirety, regardless of spatial proximity to its centre. Then, regeneration interventions should be targeted primarily at areas with a significant peripheralization risk, understood as a combination of potential degradation factors. Consequently, the decision-makers’ choice of the best design alternative should be informed by the knowledge of pre-existing vulnerability levels, and oriented towards the solution that maximizes their reduction. This is possible when the planning of interventions in the most vulnerable areas, through Urban Regeneration Programs, is able to take into account the results of the project alternatives economic evaluation. Such an approach constitutes the main novelty of the study. So, the aim of the work is to provide a decision support model for the evaluation of urban regeneration interventions effectiveness in areas of high peripheralization risk. To this end, the contribution defines a set of mitigation indicators and the assessment of the most effective design alternative through analytic hierarchy process (AHP). The proposed model was applied to an area of Marcianise Municipality, in Campania Region (Italy).
A New Macro-Model of Gas Flow and Parameter Extraction for a CMOS-MEMS Vacuum Sensor
Authors: Chen Shu-Jung , Wu Yung-Chuan
Published: September 2020

When using a MEMS sensor to measure the vacuum of a medium, the transition flow between the viscous flow and molar flow is usually used to describe the gas convection due to the physical principle, which is difficult to study through analysis and simulation. In this study, the description of gas flow under different pressures in a CMOS-MEMS vacuum sensors has been incorporated into a new behavioral ANSYS model. The proposed model was built and the characteristic parameters in the model were obtained based on a CMOS-MEMS thermopile patterned with circular symmetry and an embedded heater as a heat source. It contains a characteristic length to describe the effective distance of heat dissipation to the silicon substrate, and the corresponding transition pressure to describe the symmetrical phenomenon of gas heat conduction. The macro-model is based on the description of the physical characteristics of heat transfer and the characteristic parameters of the CMOS-MEMS vacuum sensor. The characteristic length of 49 μm and the corresponding transition pressure of 2396 mTorr for the thermoelectric-type vacuum sensor were extracted and verified successfully. The results show that the average error for the prediction of vacuum sensing by the macro-model we proposed is about 1.11%. This approach provides more applications for vacuum analysis. It can reduce the complexity of simulation and analysis and provide better simulation effects, including gas conduction mechanisms.
Determination of Young’s Moduli of the Phases of Composite Materials Reinforced with Longitudinal Fibers, by Global Measurements
Authors: Szavá Renata Ildikó , Szavá Ioan , Vlase Sorin , Modrea Arina
Published: September 2020

The properties of a composite material are determined by the properties of the constitutive materials. In engineering practice, there are many situations in which we have composite material, but we do not have information about the properties of each phase component. The measurements we can make in such cases are on the existing material, thus being able to determine, experimentally, the global physical properties of the composite. The possibility of realizing an estimate of the mechanical properties of each component poses a problem if we start from these measurements. The paper proposes a method to achieve this, starting from the theoretical estimates established in the literature, then illustrated by an example to determine the properties of wood. Wood is a transverse isotropic material and therefore the constitutive law has symmetries that are manifested in the decrease of the number of parameters that define the stress-strain liason, defined only by five independent parameters. The proposed method can be extended to a diversity of models and materials used in the study of composite materials.
Eliciting Correlated Weights for Multi-Criteria Group Decision Making with Generalized Canonical Correlation Analysis
Authors: Santos Francisco J. dos , Coelho André L. V.
Published: September 2020

The proper solution of a multi-criteria group decision making (MCGDM) problem usually involves a series of critical issues that are to be dealt with, among which two are noteworthy, namely how to assign weights to the (possibly distinct) judgment criteria used by the different decision makers (DMs) and how to reach a satisfactory level of agreement between their individual decisions. Here we present a novel methodology to address these issues in an integrated and robust way, referred to as the canonical multi-criteria group decision making (CMCGDM) approach. CMCGDM is based on a generalized version of canonical correlation analysis (GCCA), which is employed for simultaneously computing the criteria weights that are associated with all DMs. Because the elicited weights maximize the linear correlation between all criteria at once, it is expected that the consensus measured between the DMs takes place in a more natural way, not necessitating the creation and combination of separate rankings for the different groups of criteria. CMCGDM also makes use of an extended version of TOPSIS, a multi-criteria technique that considers the symmetry of the distances to the positive and negative ideal solutions. The practical usefulness of the proposed approach is demonstrated through two revisited examples that were taken from the literature as well as other simulated cases. The achieved results reveal that CMCGDM is indeed a promising approach, being more robust to the problem of ranking irregularities than the extended version of TOPSIS when applied without GCCA.
Towards a Secure and Scalable IoT Infrastructure: A Pilot Deployment for a Smart Water Monitoring System
Authors: Overmars Anthony , Venkatraman Sitalakshmi
Published: September 2020

Recent growth in the Internet of Things (IoT) looks promising for realizing a smart environment of the future. However, concerns about the security of IoT devices are escalating as they are inherently constrained by limited resources, heterogeneity, and lack of standard security controls or protocols. Due to their inability to support state-of-the-art secure network protocols and defense mechanisms, standard security solutions are unsuitable for dynamic IoT environments that require large and smart IoT infrastructure deployments. At present, the IoT based smart environment deployments predominantly use cloud-centric approaches to enable continuous and on-demand data exchange that leads to further security and privacy risks. While standard security protocols, such as Virtual Private Networks (VPNs), have been explored for certain IoT environments recently, the implementation models reported have several variations and are not practically scalable for any dynamically scalable IoT deployment. This paper addresses current drawbacks in providing the required flexibility, interoperability, scalability, and low-cost practical viability of a secure IoT infrastructure. We propose an adaptive end-to-end security model that supports the defense requirements for a scalable IoT infrastructure. With low-cost embedded controllers, such as the Raspberry Pi, allowing for the convergence of more sophisticated networking protocols to be embedded at the IoT monitoring interface, we propose a scalable IoT security model integrating both the IoT devices and the controller as one embedded device. Our approach is unique, with a focus on the integration of a security protocol at the embedded interface. In addition, we demonstrate a prototype implementation of our IoT security model for a smart water monitoring system. We believe that our modest first step would instill future research interests in this direction.

Published: September 2020

Three-dimensional printing (3DP) is at the forefront of the disruptive innovations adding a new dimension in the material fabrication process with numerous design flexibilities. Especially, the ability to reinforce the plastic matrix with nanofiber, microfiber, chopped fiber and continuous fiber has put the technology beyond imagination in terms of multidimensional applications. In this technical paper, fiber and polymer filaments used by the commercial 3D printers to develop fiber-reinforced composites are characterized to discover the unknown manufacturing specifications such as fiber–polymer distribution and fiber volume fraction that have direct practical implications in determining and tuning composites’ properties and their applications. Additionally, the capabilities and limitations of 3D printing software to process materials and control print parameters in relation to print quality, structural integrity and properties of printed composites are discussed. The work in this paper aims to present constructive evaluation and criticism of the current technology along with its pros and cons in order to guide prospective users and 3D printing equipment manufacturers on improvements, as well as identify the potential avenues of development of the next generation 3D printed fiber-reinforced composites.

Published: September 2020

Acute kidney injury (AKI) is the major complication of rhabdomyolysis. We aimed to identify the predictive factors for AKI and renal replacement therapy (RRT) requirement in poisoning-associated rhabdomyolysis. We conducted a cohort study including 273 successive poisoned patients (median age, 41 years) who developed rhabdomyolysis defined as creatine kinase (CK) >1000 IU/L. Factors associated with AKI and RRT requirement were identified using multivariate analyses. Poisonings mainly involved psychotropic drugs. AKI occurred in 88 patients (37%) including 43 patients (49%) who required RRT. Peak serum creatinine and CK were weakly correlated (R2 = 0.17, p < 0.001). Death (13%) was more frequent after AKI onset (32% vs. 2%, p < 0.001). On admission, lithium overdose (OR, 44.4 (5.3–371.5)), serum calcium ≤2.1 mmol/L (OR, 14.3 (2.04–112.4)), female gender (OR, 5.5 (1.8–16.9)), serum phosphate ≥1.5 mmol/L (OR, 2.0 (1.0–4.2)), lactate ≥ 3.3 mmol/L (OR, 1.2 (1.1–1.4)), serum creatinine ≥ 125 µmol/L (OR, 1.05 (1.03–1.06)) and age (OR, 1.04 (1.01–1.07)) independently predicted AKI onset. Calcium-channel blocker overdose (OR, 14.2 (3.8–53.6)), serum phosphate ≥ 2.3 mmol/L (OR, 1.6 (1.1–2.6)), Glasgow score ≤ 5 (OR, 1.12; (1.02–1.25)), prothrombin index ≤ 71% (OR, 1.03; (1.01–1.05)) and serum creatinine ≥ 125 µmol/L (OR, 1.01; (1.00–1.01)) independently predicted RRT requirement. We identified the predictive factors for AKI and RRT requirement on admission to improve management in poisoned patients presenting rhabdomyolysis.
Phages in Anaerobic Systems
Authors: Hernández Santiago , Vives Martha J.
Published: September 2020

Since the discovery of phages in 1915, these viruses have been studied mostly in aerobic systems, or without considering the availability of oxygen as a variable that may affect the interaction between the virus and its host. However, with such great abundance of anaerobic environments on the planet, the effect that a lack of oxygen can have on the phage-bacteria relationship is an important consideration. There are few studies on obligate anaerobes that investigate the role of anoxia in causing infection. In the case of facultative anaerobes, it is a well-known fact that their shifting from an aerobic environment to an anaerobic one involves metabolic changes in the bacteria. As the phage infection process depends on the metabolic state of the host bacteria, these changes are also expected to affect the phage infection cycle. This review summarizes the available information on phages active on facultative and obligate anaerobes and discusses how anaerobiosis can be an important parameter in phage infection, especially among facultative anaerobes.

Authors: Kaplan Gordana
Published: September 2020

Surface water is one of the most vital Earth resources changing in time and space as a consequence of land use/land cover (LULC) changes, climate change, and other environmental factors. Timely monitoring of the water area and its surroundings is essential for policy and decision-making processes. Monitoring the land cover changes with conventional methods may consume significant time and resources. With the development of remote sensing, land cover monitoring has become practical and effective. The most practical way for monitoring the changes is with the classification of satellite imagery. The main aim of the study is to make a five-year land cover change in a watershed using remote sensing data. For this purpose, two satellite images, from RapidEye-3 and Sentinel-2 have been classified. As a study area, the Prespa Lake watershed has been selected. The Prespa Lake is situated in the Balkan Peninsula and is shared among Albania, North Macedonia, and Greece. For the purpose of the study, a semi-automated object-based classification model has been developed. The results from the classification showed significant accuracy of 93 – 96%. For future studies, it is recommended further investigation, such as using monthly satellite imagery and modeling precipitation and meteorological data.

Published: September 2020

Drought risk has become a major threat for sustaining food security in Bangladesh; the particularly northwestern region of Bangladesh. The objective of the study is to assess drought disaster risk on Boro paddy cultivated areas of northwestern Bangladesh using drought disaster risk index (DDRI) model. The sensitivity of Boro paddy to droughts during crop-growing seasons and irrigation recoverability were employed to reflect vulnerability condition. Moreover, the threshold level of the standardized precipitation evapotranspiration index (SPEI) was applied to evaluate the drought hazard on Boro paddy cultivated areas in the northwestern region of Bangladesh. The probability density function (PDF) was used to show the threshold level of drought hazard. The results show that drought hazard is comparatively severe in Ishardi area compared to other northwestern regions of Bangladesh. The drought disaster risk is higher in Ishardi and Rajshahi areas than Rangpur and Dinajpur areas. Although Ishardi area is more prone to high drought risk, at the same time, the recoverability rate is also quicker than any other areas. The relationship between Boro rice yield rates and drought disaster risk is insignificant. The average Boro yield rates during the period of 1976 to 2016 are 19% for Ishardi and Rajshahi areas, 20% for Rangpur and Dinajpur areas and 21% for Bogra respectively according to the total irrigation area. The outcomes of the study can aid to adopt drought condition under changing the climate and also provide guidance for future drought mitigation in the northwest region of Bangladesh.

Authors: Kohansal Mohammad Mahdi , Eslamian Saeid , Saadati Sara
Published: September 2020

Population growth and the need for sustainable urban development as well as lack of water resources due to the position of Iran in the arid and semi-arid zone and the occurrence of recent drought has seriously raised the importance of water scarcity. Nowadays, unconventional water resources are considered as one of the possible solutions to provide water supplies. Among different resources of unconventional waters, the use of wastewater as a sustainable resource for water scarcity management is considered as a strategic strategy. The aim of this study was to compare biological treatment method and nanofiltration method to remove sulfate from industrial wastewater. Thus, industrial wastewater of Najaf Abad treatment plant was used for this purpose and the experiments were carried out for 11 weeks and 11 replications. The appropriate method was chosen by calculating the removal percentage of various parameters and SPSS software was used to analyze the significance of the difference between the results of the two methods. According to the results, the percentage of sulfate removal in all experiments in the nanofiltration system was higher than the biological system and nanofiltration method is more reliable to remove sulfate. So, nanofilter system would be a good alternative for the biological system to reduce and remove sulfate in industrial wastewater.

Published: September 2020

The state of ecological systems, along with their general characteristics, is almost always described by indicators that vary in space and time, which leads to a significant complication of constructing mathematical models for predicting the state of such systems. One of the ways to simplify and automate the construction of mathematical models for predicting the state of such systems is the use of machine learning methods. The article provides a comparison of traditional and based on neural networks, algorithms and machine learning methods for predicting spatio-temporal series representing ecosystem data. Analysis and comparison were carried out among the following algorithms and methods: logistic regression, random forest, gradient boosting on decision trees, SARIMAX, neural networks of long-term short-term memory (LSTM) and controlled recurrent blocks (GRU). To conduct the study, data sets were selected that have both spatial and temporal components: the values of the number of mosquitoes, the number of dengue infections, the physical condition of tropical grove trees, and the water level in the river. The article discusses the necessary steps for preliminary data processing, depending on the algorithm used. Also, Kolmogorov complexity was calculated as one of the parameters that can help formalize the choice of the most optimal algorithm when constructing mathematical models of spatio-temporal data for the sets used. Based on the results of the analysis, recommendations are given on the application of certain methods and specific technical solutions, depending on the characteristics of the data set that describes a particular ecosystem

Authors: Ogurtsov Alexander , Dmitriev Vasiliy
Published: September 2020

Health equality and public health promotion have been and remain relevant throughout the world. The social environment plays a leading role in addressing this issue, along with the geographical one. The complexity and multifactorial social environment lead to the use of integral assessment methods taking into account individual criteria.

This article presents the results of an integral assessment of the social determinants of public health at the municipal level. As an individual evaluation criteria were used by 8 indicators that characterize the state of employment, conditions of development and education at an early age, the state of food security, living conditions, the state of crime and the availability of primary health care. ASPID method of randomized composite indicator was used to integrated assessment for social determinants of health.

As an example, the article cites the results of two scenarios of calculation and evaluation, social determinants, determining the degree of social benefits in relation to the public health of the population of municipal urban districts Kaliningrad Region. Map models reflecting the spatial variability of integrated assessments are presented.

Analysis of the results in the first scenario showed that when there is no preference for any of the indicators, social conditions regarding public health in most municipalities are characterized as “relatively favorable — favorable”.

In the second scenario, where primary care accessibility rates are a priority, in most counties social conditions can be described as “favorable — most favorable”.

The results of an integrated assessment of social determinants can be useful for decision-makers on public health issues.

Tasks. The author considers the main differences between traditional and Islamic banks, systematizes the types of risks in Islamic banks, analyzes Sharia and economic risks, and examines the potential risks of Islamic financial institutions through the example of the Amal Financial House.

Methods. This study uses the dialectical method, methods of statistical research, classification, systems and structural analysis, graphical analysis, generalization and systematization, scientific methods of cognition (observation, comparison, analysis, and synthesis).

Results. The main differences between traditional and Islamic banks and the types of risks in Islamic banks are systematized. The system of Sharia control is considered through the example of an Is lamic financial organization (Islamic banking). Through the example of the Amal Financial House, the major risks are identified — for Islamic banking in financing using such Islamic financial instruments as murabaha and ijara, and for investors using mudaraba.

Conclusions. Systematization of the main differences between Islamic and traditional banks shows that operations are based on a real asset to exclude contradictions with Sharia (Islamic canon law). The author distinguishes between two types of risk in Islamic banks: economic and Sharia. Sharia control is divided into internal and external (through the example of the Amal Financial House), which ensure the functioning of Islamic banking to prevent risk in unauthorized transactions within the framework of Islam. The author analyzes the activities of the Amal Financial House in 2015-2019 related to financing using such Islamic financial instruments as murabaha and ijara. The return on investment products shows positive dynamics, i.e. investors receive a steady income, even though there is a risk of losing the invested funds.

Consideration on High Performance Concrete (HPC) has risen drastically because of the requirement for application of concrete volume with high strengths for construction work. In this study, the mechanical properties of HPC with Guinea Corn Husk Ash (GCHA) as supplement of cement was investigated. The proportioning of Ordinary Portland Cement (OPC) with GCHA is from 0 - 20%. Design of the concrete mix was done to achieve a characteristic strength of 50 N/mm². The chemical composition of the GCHA was determined using X-ray Fluorescence (XRF)  Slump and compacting factor of fresh HPC were determined. Concrete cubes (for compressive strength), beams (for flexural strength) and cylinder (for split tensile strength) samples were cast and cured in water for 7 - 56 days. Density, compressive, flexural, and split tensile strengths were determined on the hardened HPC and were further examined using SEM analysis. Compressive strength at 56 days showed that control and inclusion of 5% GCHA gave strength 56.85 N/mm2 and 57.76 N/mm2, respectively above the designed target strength of 56.56 N/mm2 while inclusion of 10% GCHA met characteristics strength of 50 N/mm2. However, 5% GCHA-concrete had the highest flexural and split tensile strengths at 56 days of curing. Integration of 10% GCHA as replacement of OPC would produce concrete of higher strengths compared to conventional HPC at longer curing age. Based on the SEM results, uniform distribution of filler was obtained at 10% GCHA inclusion. At higher percentage of GCHA, resulting composite presents multiple and distinct grains with possible weak interfaces.
Effect of Rice Husk Ash on the Hydraulic Conductivity and Unconfined Compressive Strength of Compacted Bentonite Enhanced Waste Foundry Sand

A laboratory study of the hydraulic conductivity, (HC), and unconfined compressive strength, (UCS), of compacted bentonite enhanced waste foundry sand (BEWFS) treated with rice husk ash, (RHA) for possible use as liner material is presented. The bentonite enhanced waste foundry sand, BEWFS, was obtained by blending waste foundry sand (WFS) with 12% bentonite by weight of the WFS and mixing the resulting blend thoroughly to obtain a homogenous mix. RHA was added to the BEWFS in increment of 2, 4, 6, 8 and 10% respectively of the dry weight of the BEWFS. The entire blended material was thoroughly mix together to obtain sample with different content of RHA. Index tests, compaction, UCS and HC tests were carried out on the blended materials to determine the effect of RHA on the behaviour of the BEWFS. HC as well as UCS of the materials were study using three compactive efforts of British standard light, (BSLC), West African standard, (WASC) and British standard heavy, (BSHC) compactive efforts respectively. The results obtained show that addition of RHA to BEWFS affected the index properties of the material marginally where the liquid limit increased to 35 from 32 %, plastic limit reduced from 12 to 11% and plasticity index increased from 20 to 25% respectively. The HC of the material was found to increase slightly from 6.28 x 10-08 to 3.90 x 10-08, 2.64 x 10-09 to 2.07 x 10-08 and 8.55 x 10-11 to 1.83 x 10-10 m/s with addition of up to 10 % RHA content and compacted at BSLC, WASC and BSHC respectively. Similarly, the UCS was found to increase to peak values of 177.22, 288.48 and 454.26 kN/m2 at same RHA content and compactive efforts. The implication of this result is that the addition of RHA up to 10% to BEWFS slightly increase the HC but does not compromise it while the strength gain in term of UCS can be said to compensate for the slight lost in HC. It is recommended that BEWFS treated with between 8 to 10% RHA content and compacted at BSHC compactive effort can be applied as liner in engineered waste containment system.

Most studies and research have tried to shed light on unemployment and employment in general, with less focus on the problems facing working women and the resulting social and economic consequences that threaten their human and professional lives. For women, working is one of the basic necessities for the sustainability of human life, and it constitutes an essential axis for both sexes and through it. It also gives a person the status and social status where the individual finds a ready opportunity to practice his intentions and desires, test his abilities and talents, and achieve his ambitions. The availability of full employment in general and the joining of women to the labor market is an important and fundamental factor in the sustainability of development. However, this contribution faces a series of obstacles due to the cultural environment and the social determinants that women face in Iraqi society, especially in the field of work in the informal sector, where society imposes strict restrictions on the quality and place of work.....

The climate is one of the natural factors affecting agriculture, and the success of the cultivation of any agricultural crop depends on the nature of the prevailing climate in the area of its ​​cultivation. If the main elements of climate: temperature, rain and humidity, affect the various agricultural activities that can be practiced, and the stages of growth of agricultural crops and also determine the areas of spread. When the climatic requirements of any crop are well available, its cultivation is successful and comfortable. The research starts from the problem of spatial variation of date production spatially in the study area and the reason for choosing dates because of its economic importance, so the research will be based on the discussion of a basic hypothesis related to the relationship of climate central and southern Iraq to cultivate dates and spatial variability and prove the validity of this hypothesis and achieve the objectives of the study. Quantitative approach is used in different parts of the research to reach the conclusions of the research. It shows that the northern regions of the study area occupy the highest areas in the number of palm trees that are less in the south and east of the study areas, and that there is a strong correlation between certain types of dates and climatic elements that are represented by (the maximum and minimum temperatures and the relative humidity) while there are types Dates are associated with (manpower).
