The paper studies the science of “Biomimicry” or imitation of nature, and how to utilize it to create contemporary designs. It starts by defining biomimicry and innovation. Then, the style of imitating nature is highlighted, which is considered one of the most important methods of innovation. It includes simulating animals and plants (in their environmental conditions) to use the natural and dynamic design solutions to produce innovative designs, that enhance the concept of sustainability. Various forms of natural species are presented, to show their benefit in contemporary metal product designs. Finally, a model of a metal lighting unit is developed, where innovative ideas inspired by silkworm cocoon are used in its design. The stud

Background: Studying and investigating the transverse strength(Ts), impact strength(Is), hardness (Hr) and surface roughness(Ra) of conventional and modified autopolymerizing acrylic resin with different weight percentages of biopolymer kraftlignin, after curing in different water temperatures; 40°C and 80°C. Material and Methods: Standard acrylic specimens were fabricated according to ADA specification No.12 for transverse strength, ISO 179 was used for impact testing, Shore D for hardness and profilometerfor surface roughness. The material lignin first dispersed in the monomer, then the powder PMMA is immediately added. Ligninadded in different weight percentages. Then cured using pressure pot (Ivomet) in two temperatures;40°C a

The figure of personality modes determines its privileged style in the use of modern and advanced technological tools in the process of changing and developing in order to keep up with that. The proses of selection and choosing administrators in the appropriate places are the most important functions of senior management because it is easy to adopt factory buildings or establishments But this is a human world as that of machines world. So it is required to have people in the process of changing those who have a time, Knowledge, skill, ability and strong administrative personal skills, those people (leaders) should to put a clear vision for the selection and application of the change efforts and to create the necessary climate and

أظهرت معركة غزة (سيف القدس) رؤية الصين وروسيا تجاه الصراع الاسرائيلي الفلسطيني، لكونهما يتمتعان بعلاقات جيدة مع طرفي الصراع، وهذا مكنهما من أن يطرحوا رؤية لمشروعهم للوصول الى حل سلمي يرضي الطرفين، ونابع من مصالحهما الاقتصادية والسياسية في منطقة الشرق الاوسط، فالصين لديها رؤية كاملة من خلال مشروعها (مبادرة الحزام والطريق)، اما روسيا فهي حريصة على المحافظة على وجودها الجيوسياسي واستثماراتها في (خطوط الغاز) عل

   أن الأسلوب الوصفي للبحث في طبيعة حق حرية الرأي والتعبير للفرد قد لايقودنا الى فهم طبيعة هذا الحق والمسؤولية المترتبة عليه كما هو الحال في الأسلوب التجريبي التحليلي ، لأننا لسنا بصدد دراسة حالات شاذة للأراء والتعابير والسلوكيات ، ولكننا بصدد دراسة طبيعة المؤثرات البايلوجية والنفسية والذاتية والنفسية الأجتماعية التي توصل الأختلاف في الرأي والتعبير الى مستوى حقاً من حقوق الحرية الطبيعية للفرد ،

This research dealt with highlighting the images of marriage through the modern means of communication and the legal ruling for it. Dowry even be knotted on them; because they are then one of the parties to the contract and contracted in one contract, and this is prohibited by law and law and common sense.

It turns out that it is permissible to advertise marriage through the Internet in accordance with the rules and standards that preserve values ​​and morals and safeguard dignity and chastity. The acts in Islamic law are vested with intentions. If intentions are true, then the act is true, and Internet marriage is what falls under this order.<

Objectives: Semen analysis is the cornerstone for the valuation of the male partner in the infertile couples. This test has been standardized throughout the world through the World Health Organization (WHO) since the1970s by producing, editing, updating, and disseminating a semen analysis manual and guidelines. A retrospective study to give an insight about  male infertility. Methods: This retrospective study assessed the semen findings of 1000 men evaluated at the  Department of Urology, Al-Kindy Teaching Hospital in Baghdad-Iraq  between January 2016 and May 2019. Semen analysis were done for them. Results: According to WHO standard for semen normality, 1000 samples that were analyzed, normospermia was shown in 835 (83.5%)males

Enzymatic hydrolysis process of lignocellulosic biomass materials is difficult because of inherent structural features of biomass, which represents barriers that prevent complete hydrolysis; therefore, pretreatment techniques are necessary to render biomass highly digestible in enzymatic hydrolysis process. In this research, (non?) oxidative short-term lime pretreatment of willow wood was used. A weight of  11.40 g of willow wood was mixed with an excess of calcium hydroxide (0.4 g Ca(OH)₂/g raw biomass) and water loading (15 g/g raw biomass). Lime pretreatment was carried out for various periods of time including 1, 2, 3.5, 5 and 6 h, with temperatures at 100, 113, 130, 147 and 160⁰C, and oxygen pressures as o
