The impact of population density in sustainable housing - An applied study in the city of Baghdad (Mahalla 817), Al-Bayaa as a model
...Show More Authors

Population density represents an important indicator for determining the growth of the size of urban areas. Population density has a direct impact on the quality of life, and its excessive rise may lead to the deterioration of basic service facilities. The problem of the research is that the increase in the total population densities of the residential neighborhood may reflect negatively on the nature of the services provided to the residents in these shops, and thus the failure to achieve sustainability in the residential locality. The research assumes that the increase in population densities negatively affects the achievement of sustainability in the residential neighborhood.

 

         And within the theoretical framework of the research, the concepts of population and housing densities and their levels, concepts related to housing, dwelling, and the residential environment, and the link between these concepts were reviewed, while addressing the concept of sustainability in the urban environment, and the concepts of the residential neighborhood, with mentioning of the social, urban-planning and environmental indicators to achieve sustainability in the residential neighborhoods. Where, a set of indicators (social, urban planning, and environmental) were reached that represent the requirements for the sustainability of the residential neighborhood.

 

        As for the practical framework of the research, it was carried out within a field study of the Al-Bayaa neighborhood (817), to identify the social and urban characteristics of the area, and to identify the change in its population densities and the reasons behind the increase in its population by questioning the residents’ opinions about the requirements for the sustainability of the residential neighborhood, and then conducting a statistical and planning analysis of the results of the residents’ questionnaire using statistical methods to ensure that there are real or marginal differences for the researched periods (the time of construction, the present time, the present time of the old residents), and

 

          the results of the statistical and planning analysis were summarized for all the requirements that were presented through the final evaluation of all the requirements that decreased its level compared to what it was at the time of construction, which has regressed from the situation it was in previously, and whose level has risen from the previous one.

      To achieve the goal of the research, the researcher relied on proving his hypothesis on the descriptive analytical approach in achieving the goal of the research and reaching the final result, which depends on understanding the problem of the study, and finding appropriate solutions to it, by studying the changes in population densities of the neighborhood during two different periods within the study area (District 817 in Al-Bayaa), and to obtain data and information about the study area, the researcher used the questionnaire to collect information about the study area.

 

        The most important results reached in this research are the low requirements for achieving the sustainability of the neighborhood (social, urban - planning, environmental) as a result of the effects of the increase in population density in the study area affecting negatively these requirements such as (community and neighborhood, population density, existence of open and green spaces), with a number of indicators that have declined significantly from what they were previously such as (social interaction, the formation of the social convergence opportunities, the efficiency of roads, recreational areas) and a number of indicators that were positively affected by this increase such as (the availability of gathering spaces within the urban formation for the residential neighborhood, and water availability).

         Finally, the most important recommendations of the study were the need to support the indicators of the sustainability of the residential community by increasing social interaction in the residential community and enhancing the individuals' sense of security, safety, social solidarity, community unity and neighborhood by maintaining levels of homogeneity in the formation of urban spaces and providing privacy for housing units in the built environment and not allowing encroachment on Building controls, while strengthening the social relations between the residents of the residential locality and opportunities for social convergence through the optimal use of land uses and encouraging recreational activities, while preserving the residential environment of the residential locality by limiting modifications to housing units to reduce the opportunities for newcomers and limit the change in the pattern of residential land uses To commercial or direct its activities through legislation that limit it.

Efficiency Evaluation of Optical System Includes Different Stop Apertures When Using Relative Moving Factor
...Show More Authors

In this work, optical system with different aperture shapes (circular, square, elliptical and triangle aperture) has been used for efficiency evaluation when the system involved moving factor in ideal case (aberration free). The optical system evaluate far moving object, therefore the image forming at image plane due to point spread function (image formula of incoherently illuminated point object). A mathematical treatment has been used to getting results by Gaussian numerical calculations method. The results show priority of circular aperture when optical system that submits of moving factor.

Biosynthesis, Characterization, Adsorption and Antimicrobial studies of Vanadium Oxide Nanoparticles Using Punica Granatum Extract
...Show More Authors

This study includes using green or biosynthesis-friendly technology, which is effective in terms of low cost and low time and energy to prepare V2O5NPs nanoparticles from vanadium sulfate VSO4.H2O using aqueous extract of Punica Granatum at a concentration of 0.1M and with a basic medium PH= 8-12. The V2O5NPs nanoparticles were diagnosed using several techniques, such as FT-IR, UV-visible with energy gap Eg = 3.734eV, and the X-Ray diffraction XRD was calculated using the Debye Scherrer equation. It was discovered to be 34.39nm, Scanning Electron Microscope (SEM), Transmission Electron Microscopy TEM. The size, structure, and composition of synthetic V2O5NPs were determined using the (EDX) pattern, Atomic force microscopy AFM. The a

Sorption of Lead, Zinc and Copper from Simulated Wastewater by Amberlite Ir-120 Resin
...Show More Authors

The presence of heavy metals in the environment is major concern due to their toxicity. In the present study a strong acid cation exchange resin, Amberlite IR 120 was used for the removal of lead, zinc and copper from simulated wastewater. The optimum conditions were determined in a batch system of concentration 100 mg/L, pH range between 1 and 8, contact time between 5 and 120 minutes, and amount of adsorbent was from 0.05 to 0.45 g/100 ml. A constant stirring speed, 180 rpm, was chosen during all of the experiments. The optimum conditions were found to be pH of 4 for copper and lead and pH 6 for zinc, contact time of 60 min and 0.35 g of adsorbent. Three different temperatures (25, 40 and 60°C) were selected to investigate the effect

Antibiotics adsorption from contaminated water by composites of ZSM-5 zeolite nanocrystals coated carbon
...Show More Authors

The presence of antibiotic residues such as ciprofloxacin (CIPR) in an aqueous environment is dangerous when their concentrations exceed the allowable. Therefore, eliminating these residues from the wastewater becomes an essential issue to prevent their harm. In this work, the potential of efficient adsorption of ciprofloxacin antibiotics was studied using eco-friendly ZSM-5 nanocrystals‑carbon composite (NZC). An inexpensive effective natural binder made of the sucrose-citric acid mixture was used for preparing NZC. The characterization methods revealed the successful preparation of NZC with a favorable surface area of 103.739 m2/g, and unique morphology and functional groups. Investigating the ability of NZC for adsorbing CIPR antibioti
