Architectural and ecological development   model   can be  identified   by  studying genetic evolution of living beings and their surrounding environment, which makes every one of them complement the other, an integral part of it, and the basis of its existence. Architects started to get back to nature to look for the keys for building sustainability, because elements of nature are a   creative, rich, and useful  source  of  inspiration   and   learning   for architects and designers to present sustainable designs. Getting inspired by or simulating living forms should not lead to making exact copies of them. The real lesson is to benefit from the substantial idea and the basis of the natural system composing it. This leads us to the problem of the present study: There are no enough local studies on the importance and role of living nature simulation in terms of shape, composition, and structural systems to create sustainable   systems.  Hypothesis of the  study  is:  the  harmony shown  by natural, organic structures resulting from the integration of shape with structural function can be employed in architecture shapes and structures by merging shape and function in a symbiotic relationship resembling to a great extent biological , genetic development in their re-formations appearing in natural organic structures. Aim   of   the   study:   Discovering   formational   and   environmental   constraints   of elements   of   nature   and   emerging   with   applied   indications   in   the   field   of constructional   systems   simulation   of   living   nature   and   the   possibility   of transferring them to accomplish sustainable architecture. The results and conclusions shows the need , importance and effectiveness of Simulation  the Natural Living Structural Systems to Achieve sustained Architecture ,and the integration of technical solutions to create a balance between the natural environment and the manufacturers and energy exploitation, and the adoption of passive systems and merged with the systems design, integration between nature and technology. Finally we got that the final conclusions and practical framework and recommendations.
建筑和生态的发展模式可以通过研究生物及其周围环境的遗传进化来确定,这使得它们彼此相辅相成,互为组成部分,是其存在的基础。建筑师开始回归自然,寻找建筑可持续性的关键,因为自然元素是建筑师和设计师提供可持续设计的创意、丰富和有用的灵感和学习来源。从生命形式中获得灵感或模拟生命形式不应该导致完全复制它们。真正的教训是受益于构成它的自然系统的实质思想和基础。这就导致了我们当前研究的问题:没有足够的本地研究在形状、组成和结构系统方面模拟生活自然对创造可持续系统的重要性和作用。本研究的假设是:形状与结构功能相结合所产生的自然有机结构所表现出的和谐,可以通过将形状与功能以一种共生关系融合在一起,在很大程度上类似于自然有机结构中出现的生物、遗传的重组发展,从而应用于建筑形状和结构中。研究目的:发现自然元素的形成和环境约束,并在建筑系统模拟生活自然领域出现应用指示,并将其转移到实现可持续建筑的可能性。结果和结论表明,模拟自然生活结构系统以实现可持续建筑的必要性、重要性和有效性,以及整合技术解决方案以创造自然环境与制造商和能源开发之间的平衡,以及采用被动系统和融合系统设计,自然与技术之间的融合。最后得出了最后的结论和实践框架及建议。

Tourism is an economic aspect and a real engine of development in many countries. The importance of this aspect lies in the development of various sectors starting with architecture, urban development, as well as its contribution to the balance of performance and job creation, and its positive impact on the other sectors of the industry and trade in general, and architecture in particular. Architecture forms the physical and cultural dimension of tourism, all tourist activities are held in architectural facilities and many of the architectural facilities have become important tourist attractions. This creates a positive correlation between economic, social, urban development and the preservation of resources including the cultural heritage, especially those related to architectural heritage and traditional urban figures. Where sustainable tourism can be viewed as an industry that fulfills the functional need of the tourist without prejudice the location which to be invested, especially when the site has a historical or cultural significance or even the collective memory of the community. Therefore, the research problem focused on the knowledge deficit in studying the aspects of sustainable development and its role in tourism and its mutual effects on the urban heritage of cities in terms of their points of view and indicators and how to deal with them in order to achieve sustainable tourism for those places, If we consider sustainability is the environmentally conscious in tourism and architecture. The aim of this research is to draw the aspects of sustainable tourism in all its intellectual and applied dimensions and their impact on the urban heritage sites in order to promote these places to achieve the highest possible efficiency for sustainable tourism in the long term, with regard to their developments and their various impacts (social, environmental and economic) on those places.
旅游业是经济的一个方面,是许多国家发展的真正动力。这方面的重要性在于从建筑,城市发展开始的各个部门的发展,以及它对绩效和创造就业机会的平衡的贡献,以及它对工业和贸易的其他部门的积极影响,特别是建筑。建筑构成了旅游的物质和文化维度,所有的旅游活动都在建筑设施中进行,许多建筑设施已成为重要的旅游景点。这在经济、社会、城市发展和包括文化遗产在内的资源保护之间创造了一种积极的联系,特别是与建筑遗产和传统城市人物有关的资源。可持续旅游可以被视为一种满足游客功能需求而不影响投资地点的产业,特别是当该地点具有历史或文化意义,甚至是社区的集体记忆时。因此,研究问题集中在研究可持续发展及其在旅游业中的作用及其对城市遗产的相互影响方面的知识赤字,以及如何处理这些方面的知识赤字,以实现这些地方的可持续旅游。如果我们认为可持续性是旅游和建筑中的环境意识。本研究的目的是绘制可持续旅游的所有知识和应用方面及其对城市遗产地的影响,以便促进这些地方在长期可持续旅游的发展及其对这些地方的各种影响(社会,环境和经济)方面实现最高可能的效率。

In this study, cork stopper particles were used as a low cost biosorbent to remove the cationic dyes (Methylene blue (MB), Malachite green (MG), and Methyl violet (MV)) from simulated wastewater. Batch sorption experiments of components were conducted as a function of pH, sorbent dosages, contact time, agitation speed, and particle size to optimize the best conditions for maximum removal efficiencies of dyes. The experimental data fitted slightly best to the Langmuir isotherm model than to Freundlich and Temkin isotherm model. The experimental data proved that the adsorption kinetic of MB, MG, and MV could be described by a pseudo-second order model. The results indicate that cork adsorbs dyes efficiently and could be employed as a low-cost alternative in wastewater treatment for the removal of cationic dyes.
本研究采用软木塞颗粒作为低成本的生物吸附剂,对模拟废水中的阳离子染料(亚甲基蓝(MB)、孔雀石绿(MG)和甲基紫(MV))进行了脱除。以pH、吸附剂用量、接触时间、搅拌速度和粒径为参数,进行了组分的批量吸附实验,以优化染料去除效率的最佳条件。实验数据对Langmuir等温线模型的拟合略好于Freundlich和Temkin等温线模型。实验数据表明,吸附动力学可以用拟二阶模型来描述。结果表明,软木对染料有较好的吸附作用,可作为一种低成本的废水处理方法来去除阳离子染料。

Magnetic nanoparticles are now being investigated widely in field of water treatment. The aim of this study was to evaluate the feasibility of electrocoagulation process combined with addition of magnetite nanoparticles as a turbidity removal process. Bentonite was used as source of turbidity for the synthetic turbid water. Experiments were conducted in a bench scales electrocoagulation reactor where voltage was applied across a perforated plate of aluminum as anode, and iron mesh as cathode. Commercial grade of magnetite (Fe3O4) with an average nanoparticle size of 50 nm was used. The effect of some factors such as initial pH of the solution (5-9), current density (5-25 mA/cm2), and magnetite dosage (0.4-2.5 gm) on the efficiency of the process were studied. The residual turbidity obtained by using electrocoagulation process alone was (7.47 NTU) from initial turbidity of (200 NU) at constant conditions of pH 6, current density 15 mA/cm2 and electrolysis time 20 min. While under these same conditions the combined electrocoagulation + magnetite process with the added (1.4 gm) of magnetite and under the same operating conditions the residual turbidity was (4.34 NTU), which indicate that the magnetite nanoparticles enhanced the electrocoagulation process.
磁性纳米颗粒在水处理领域得到了广泛的研究。本研究的目的是评估电凝法联合添加磁铁矿纳米颗粒作为除浊工艺的可行性。以膨润土为浊度源制备合成浊水。实验在台式电凝反应器中进行,其中电压被施加在铝作为阳极的穿孔板上,铁网作为阴极。采用工业级磁铁矿(Fe3O4),平均纳米颗粒尺寸为50 nm。考察了溶液初始pH值(5 ~ 9)、电流密度(5 ~ 25 mA/cm2)、磁铁矿投加量(0.4 ~ 2.5 gm)等因素对工艺效率的影响。在pH为6、电流密度为15 mA/cm2、电解时间为20 min的条件下,初始浊度为200 NU,单电混凝得到的剩余浊度为7.47 NTU。在相同条件下,电混凝+磁铁矿联合工艺,添加磁铁矿(1.4 gm),在相同的操作条件下,剩余浊度为4.34 NTU。说明纳米磁铁矿增强了电凝过程。

The research aims to predict the efficiency of capturing the soot particles generated by the diesel generator within the Hydro Cyclone by conducting the applied study using the Computational Fluid Dynamics (CFD) application through modeling and simulation of the turbulent flow within the Hydro Cyclone using SOLIDWORKS Flow Simulation. The ability to predict the impact of such flows on your product performance is time consuming and costly without some form of simulation tools...SOLIDWORKS Flow Simulation uses Computational Fluid Dynamics (CFD) analysis to enable quick, efficient simulation of fluid flow and can easily calculate fluid forces and help the designer to understand the impact of a liquid or gas on product performance and comparing the results with experimental reality. In this research, the engineering simulation confirmed the importance of using Hydro Cyclone in the capture of diesel soot particles by an error rate of only 4% compared to experimental reality.

The possibility of utilizing waterworks sludge as byproduct from water supply treatment plant for the remediation of simulated leachate contaminated with cadmium, dissolved organic matter (COD), and ammonia nitrogen (NH3-N) was investigated through batch study in comparison with conventional sorbents specifically activated carbon and ion-exchange resin Amberlite IR120 Na. Batch sorption experiments of single and multi-components systems were conducted to represent the acetogenic phase (pH= 5.5). Results proved that the sludge, activated carbon and ion-exchange resin are efficient sorbents for removal of cadmium, COD, and NH3-N respectively with removal efficiencies ranged from 35 to 95% for all experiments. Equilibrium isotherms were analyzed using the Langmuir and Freundlich models. Kinetic data were obtained and analyzed using pseudo-first-order and pseudo second-order equations. The sorption isotherm data were fitted well to the Langmuir isotherm and the monolayer adsorption capacity was found as 5.634, 14.908 and 3.938 mg/g for sorption of Cd (II) onto sludge, NH3-N onto resin and COD onto activated carbon respectively.
通过与常规吸附剂(特别是活性炭和离子交换树脂Amberlite IR120 Na)进行对比,研究了自来水厂污泥作为给水处理厂副产物用于镉、溶解有机物(COD)和氨氮(NH3-N)污染模拟渗滤液修复的可能性。分别进行了单组分和多组分体系的间歇吸附实验,以代表醋酸相(pH= 5.5)。结果表明,污泥、活性炭和离子交换树脂是有效的吸附剂,对镉、COD和NH3-N的去除率在35% ~ 95%之间。用Langmuir和Freundlich模型分析了平衡等温线。利用伪一阶和伪二阶方程获得动力学数据并进行分析。吸附等温线数据与Langmuir等温线吻合较好,对污泥上Cd (II)、树脂上NH3-N和活性炭上COD的吸附量分别为5.634、14.908和3.938 mg/g。

A study of the evaluation of the water productivity (WP) of eggplant under subsurface water retention technology (SWRT) through membrane sheet installed under the root zone has been conducted in sandy loam soil located in Al-Fahamah Township, Baghdad, during two growing seasons (from January 10th to May 31st, 2017 in a greenhouse and from April 9th to July 10th, 2017 in open field). For this purpose, two treatments plot with membrane sheet and without using membrane sheet were applied for each growing season to determine and compare the effect of water saving membrane on productivity of eggplant. Results showed apparent differences among the water productivities of eggplant in the greenhouse and open field. The WP values of eggplant inside greenhouse for SWRT treatment and control plot were 5640 ID/m3 and 3700 ID/m3, respectively and in open field were 2220 ID/m3 and 1570 ID/m3, respectively. The WP of eggplant for SWRT treatment was more than the control plot inside the greenhouse and in open field by 52 % and 40 %, respectively. The installation of membrane sheet below the soil surface was improved the value of water productivity of eggplant and more saving in applied of irrigation water.
