Lead poisonousness is a widely recognized type of heavy metal poisoning in humans and animals. So, this study aimed to assess the ameliorative role of cranberry extract use on hematological changes induced by lead acetate in rats. A total number of 40 adult male albino rats weighing approximately 200 ± 20 g were randomly assigned into four groups; Normal control group, group 2; Positive control, lead acetate at a dose of (50 PPM) for 45 days, group 3; Lead acetate at a dose of (50 PPM) then Cranberry extract (75 mg/kg) for 45 days also group 4; Lead acetate (50 PPM) then Cranberry extract (150 mg/kg) for 45 days. Blood samples were collected in EDTA tubes for hematological examinations. Oral administration of lead acetate (50 PPM) significantly decreased total erythrocyte count, hemoglobin, packed cell volume and mean cell volume levels in comparison with the normal control group (P< 0.0001). Addition of cranberry extract at a dose of 75 and 150 mg/kg significantly increased the total erythrocyte count, hemoglobin, packed cell volume and mean cell volume levels in comparison with the positive control group (P< 0.0001). Oral administration of lead acetate (50 PPM) significantly increased total leukocytes count, lymphocyte, neutrophils, eosinophil and monocytes count in comparison with the normal control group (P< 0.0001). Addition of cranberry extract at a dose of 75 and 150 mg/kg significantly decreased the total leukocytes count, lymphocyte, neutrophils, eosinophil and monocytes count in comparison with the positive control group (P< 0.0001). Our results clearly indicate that cranberry extract ameliorates hematological changes in lead acetate-treated rats.

Nature around us is distinguished by its beautiful beauty resulting from the wonderful diversity in its patterns, formations, colors, and formative rhythms presenting in living organisms such as plants, animals and terrain of earth, including mountains, hills, plateaus, forests, rivers, seas, oceans . Patterns formations are everywhere in nature, especially if Look closely. The patterns are not only in forests, seas and sky, but also in the branches and leaves of trees, the arrangement of flower petals, animal skins, and the effect of wind movement on the desert sand. Each elements of natural is unique in a special kind of beauty that distinguishes it from others, and this great diversity has become an inexhaustible source of inspiration for designers leading to the development of the design process that seeks to achieve human well-being, by linking human inherent need to belong to nature in creating unique internal environments aimed at preserving the physical and mental health of the person and preserving The environment. This research presents the natural patterns and how they can be used in the formation of internal spaces.

All participants were followed till the end of thefirst trimester to report cases of miscarriage. Vitamin d was assessedfor the 40 women who suffered from miscarriage (cases) and for 40selected controls.The primary outcome was the relation between vitamin d level and early pregnancy loss. Secondary outcome was therelation between vitamin d deficiency and obesity.Results: Our findings showed that the miscarriage groupwas significantly olderthan control group as p (42.5%) had 25(OH)D deficiency while (40.0%)&(17.5%) of caseshad either 25(OH)D insufficiencyor sufficiency which significantlydifferent than control group (p=0.049).25(OH)D ≤24.5 (ng/mL) wasa significant factor that increased the likelihood of first-trimestricmiscarriage with sensitivity 80%.No significant differences according to BMI grades regarding 25(OH)D grades.Conclusion: Vitamin d deficiency is one of modifiable risk factors forfirst trimestric abortion. . Preconceptional vitamin D supplementationis an easy method for decreasing incidence of early pregnancy loss.

Biomimicry of color configurations in the natural environment has attracted great interest in research fields in recent years, as colors are produced in the natural environment through three main sources: bio-pigments, bioluminescence and structural colors. Structural color is a special color produced by micro or microscopic structures in living organisms where structural colors arise from complex interactions between microscopic structural surfaces and visible light and are related to the rapidly evolving field of photonics, and in principle they depend mainly on many elementary optical processes including interference Thin layer, diffraction, light scattering, optical crystals etc. In nature these processes are mixed together in multiple ways to produce complex color optical phenomena. Textured colors collaborate with pigment colors to enhance or reduce glossiness and produce special effects. It seems that structure-based optical phenomena in the natural environment are multifunctional, the diversity of which is very far from our understanding. In this research, we review these phenomena that appear in living organisms, to shed light on this rapidly developing field of research and its applications in the field of interior design and furniture. .

And the student, and previous studies have shown that a number of factors contribute to reducing the chances of success, the most important of which is the school climate where the student can learn a lot without realizing it, through his presence in a rich educational environment, The one who focuses on psychology and social ergonomic engineering enhances his intellectual and creative capacity, and this is what matters to the science of architecture and design arts.

The study aimed to know the value of new technologies for interior design spaces, including smart floors that generating electrical energy through walking steps, identifying people, analyzing the personal data, knowing marketing desire and alerting when heavy things fall on the floor. Also, identifying the impact of new technologies on the Leadership in Energy and Environmental Design (LEED) system and how contribute to achieve mandatory points and participate in different accreditation points. The Problem: The need to monitor all effects resulting from using the new technologies in interior design spaces according to the Leadership in Energy and Environmental Design (LEED) system. The shortage in interior designer’s study that shown effects in the new technologies used in interior design spaces and the relationship with the Leadership in Energy and Environmental Design (LEED) system. Objectives: Identify the new technologies, which used in interior design spaces and to arrive a relationship between new technologies and the Leadership in Energy and Environmental Design (LEED) system to achieve different aims. Methodology: Descriptive and analytical approach Resuls: The interior designers must provide a full study about how use the new technologies in the interior spaces from the initial stage until the design completed and the project implementation. Also, try to achieve the human, organic and psychological comfort, which required for each interior spaces. The interior designers must select the appropriate finishing materials inside the internal spaces according to the design criteria to ensure the proper performance of the work and using the latest technologies available during the project design and construction phase. The interior designer must arrange study to determining the spaces of reflection and absorption surfaces inside the interior spaces and FF&E items. Moreover, the internal shape and components of the interior space will be affect the sound quality inside every space. In addition, it is not necessary to use additional reflectors and new complex absorbent materials to reach the best sound performance. Furthermore, the designer must provide full sounds study for the interior design to achieve comfortably. - The most important recommendations for the designers is to use the new technology from the earliest stages of the design to enhance and achieve human, organic and psychological comfort inside the interior spaces that comply with the requirements of the Leadership in Energy and Environmental Design (LEED). Scientific institutions should provide the students and researchers information about the new technologies and LEED rating system. The Governments should provide incentives for the projects using the new technologies. Also, comply with the requirements of the Leadership in Energy and Environmental Design (LEED).

The exposure to sunlight, UV-rays led to the degradation of the pesticides formulations (Namrod 25% EC) bupirimate, (Agrozole 10% EC) penconazole and (Actacron 72% EC) profenofos. Their residues were determined by high performance liquid chromatography (HPLC). The results showed that exposure to direct sunlight in (Winter at the morning) was more effective in degradation of the tested pesticides than exposure to direct sunlight in (Winter at the evening) for 4 hours. The percentage residue of bupirimate, penconazole and profenofos were 18.24, 48.52 and 19.26 % in winter at the morning, respectively. Therefore, bupirimate was the highest affected by this treatment. Also, the data showed that exposure to direct sunlight in (Summer at the evening) was more degraded than exposure to direct sunlight in (Summer at the morning) for 4 hours. The percentage residue of bupirimate, penconazole and profenofos were 11.14, 15.45 and 7.72 % after 4 hours in (Summer at the evening), respectively. Therefore profenofos was more degraded than other pesticides. In general the degradation of the tested pesticides in summer was higher than winter. Withal, the data demonstrated that the exposure to UV-ray at distance 22.5 cm was more effective in degradation of the three tested pesticides than exposure to UV-ray at distance 45 cm for 4 hours where, the percentage residue of bupirimate, penconazole and profenofos were 17.08, 39.56 and 15.00 % after 4 hours of exposure to UV-ray at distance 22.5 cm respectively, and therefore profenofos was the highest degraded in the three pesticide in the same period of exposure to UV-ray.

Museums have become a cultural mission and multiple functions, including scientific, cultural, social, educational, behavioral and others, and in the modern era has become one of the most prominent architectural elements of the century where architects and constructionists find a great opportunity to show their artistic vision and academic study that fit the style displayed, has been designed and built many of public aquatic museums around the world during the last three decades. The study of the interior design of aquatic museums and its contents and its relation to technological development on the interior design of these museums, and to make the best use of technological development, and to achieve all the requirements of the building from the provision of architectural exterior and fulfill the design requirements of the interior.

The intensity of the illumination is different in all countries due to geographical nature, proximity or distance from the equator and time zone, which will require from the designers to have more study about illumination in interior spaces. High different illumination will effect human eye and retina with severe damage, which might lead to vision loss after expose to large period of lighting might lead to injury of many different diseases. Therefore, designers should consider the lighting gradient (high/low-light in spaces) by studying how to use lighting designs to overcome this gradient. The Problem : The shortage in interior designer’s study that appeared in the designs like high contrast illumination and its relationship with regional priority that impact on humans. Objectives : Reaching to specific criteria for regional priority. Arrange design study to provide a graduation between high/low-light spaces. Methodology : analytical descriptive approach. Results: The designer should provide a design study to identify the proper distribution of illumination intensity in different spaces. according to the activity of each space and users to achieve a comfortable sense for the eyes without any stress due to varying variations in the values of light surfaces, where the eye require a period of time to absorb and respond to the vision. When using a natural light in spaces the designer should study the long-term expose to UV radiation from the sun, as it might damage cornea and cause cataracts (white water). Therefore, must be installed suitable glass panel to control the natural illumination intensity or installed suitable curtains with transparency in the spaces. The lighting ratio between the activity space and around space should (not less than 10%). Even does not happen any temporary vision for a time up to a few seconds until the eye meets the new illumination conditions. The lighting systems contain different degrees of illumination that help the designer to control the illumination effect and provide proper distribution of illumination intensity in different spaces. Also, will help to save energy according to the Leadership in Energy and Environmental Design (LEED) system. In hot countries, the outside illumination intensity is high, when people moving from outside to inside spaces, the high different illumination intensity between spaces will affect the eye and retina with severe damage which might lead to vision loss after expose to large period of illumination. Also, might lead to injury of many different diseases. This case occurs as usual in the hotter countries.

The contemporary school yard is an influential element in developing many of the student's mental and emotional perceptions, achieving psychological balance for him and enhancing various aspects of his personality in general and for the student of Industrial Technical Education in particular, due to the values and design criteria it contains that make it the scene of many and varied theoretical and practical activities in which the teacher and the student participate in order to acquire knowledge, skills, behaviors and attitudes that prepare for life, and the school becomes the second home for students. By achieving this, the educational process will become more efficient and distinguished, and it will also necessarily lead to the advancement of traditional industries that depend on the skill and abilities of the student. There are many previous studies that have shown that the reasons for failure to achieve good success are not only due to the student's intelligence level, but rather a number of factors that contribute to reducing the chances of success, the most important of which is the school climate, where the student can learn a lot without feeling it through his presence in a rich educational environment that motivates him to love learning and connect parts to each other and enhances his mental and artistic abilities such as creativity, as creativity is not merely an independent ability or talent, but it is largely linked to the surrounding environment and the balance among these capabilities enables the student to produce creative products with a distinctive skill level, and this is what Social Ergonomic Science, which is based on Psychology, Architecture and Design Arts, is interested in (Raymond, Malouli - 2010).

Background : Polycystic ovary syndrome (PCOS) is one of the leading causes of infertility in female. It is usually associated with insulin resistance (IR), obesity, hyperlipidemia, and type II diabetes. Irisin is amyokine which increases energy expenditure and protects against insulin resistance and obesity. There were controversial studies about the levels of irisin and its relation to hormonal and metabolic changes in PCOS. This study was designed to estimate serum level of irisin in letrozole-induced PCOS in both lean and obese female rats, and to study the link between serum irisin level and some metabolic and hormonal parameters in PCOS. Material and Methods: This study was conducted on 48 young virgin female of local strain albino rats. They were randomly divided into 2 equal groups: Group I: lean group were fed on normal laboratory chow diet and Group II: A high fat diet induced obesity group and each group was subdivided into group A (control) and group B (letrozole induced PCOS). Fasting serum irisin, Lutenizig hormone (LH), Folliclular stimulating hormone (FSH), testosterone, estradiol, progesterone, insulin, glucose, triglycerides, cholesterol, LDL and HDL levels were estimated. In addition, body mass index (BMI) and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) were calculated in all groups at the end of the experiment. Results : Serum irisin level was elevated in both lean and obese PCOS groups when compared to both lean and obese control groups. In addition, obese PCOS group had significant higher level of irisin when compared to lean PCOS group. Conclusion: Serum irisin level was positively correlated with BMI, HDL and testosterone levels and negatively correlated with HOMA- IR, insulin, cholesterol, triglycerides and LDL levels. Irisin may have a role in the development of polycystic ovary syndrome. Key words: Irisin – PCOS- lean – obese.

En etudiant l'argumentation du discours daechien apres les attentats de Paris, nous avons remarque qu'il a adopte un ton defensif, ce qui prouve que les resultats des attaques du 13 novembre ne lui etaient pas favorables et qu'il tentait notamment de remedier a une popularite alteree et a une image degradee aupres des Francais musulmans. De meme, en s'adressant a son auditoire principal, les jeunes musulmans francophones, c'est la preuve pathetique qui regne sur le discours de l'editorialiste plutot que la preuve logique. Celuici a pour but de susciter la colere de l'auditoire musulman en lui faisant croire que l'une des regions musulmanes, le Châm et l'Irak, subit une croisade occidentale et que l'islam est humilie. Ce recours a l'argument du sacre est susceptible de nourrir un sentiment de revanche qui peut pousser certains jeunes musulmans a la violence. Notre analyse de l'argument d'autorite a revele que l'argumentation des propagandistes daechiens temoigne d'une interpretation extremement simpliste et litteraliste du Coran; les versets par lesquels ils authentifient leur dire sont lus hors du contexte de leur revelation. En plus, les auteurs de la revue choisissent souvent des traductions des versets du Coran qui ne rendent pas leur veritable sens, mais conviennent a leur projet de recrutement. Il

The ancient Egyptian, since the very beginning, associated with the surrounding environment, representing in the Nile, earth and heaven, including the sun, moon and stars. The sun rises and sets. The size of the moon varies across passages of disappearance, growth and completeness. The Nile level varies throughout the year during the flood that regularly occurs. The continuity of such image gave the ancient Egyptian the sense and feeling of the unity of the variable universe. The ancient Egyptian's concept of the universe represents in two straight and crossed meanings. The first meaning extends in the form of a line with the flow of the Nile in its course from the south to the north, cross-cutting with the second meaning, stretching throughout the sky with the sun's daily journey from the east to the west. Therefore, the Egyptian designer remains controlling the surrounding environment, which makes him fond of the idea of eternity and renewal. The ancient Egyptian always refers to the eternal truth (renewal and continuity). The land of Egypt constitutes the source of truth, whereas it remains forever, moreover it is the whole universe. Hence, all the ancient Egyptian's products reflect such idea. The temple embodies the story of creation on the land of Egypt, so what about furniture? Particularly the furniture in the complete and mature image was represented in the Throne of King Tutankhamun. The significance of research is defined through attempting to answer the following questions: - Is the furniture represented in the throne of King Tutankhamun reflection for the same Truth (renewal and continuity)? - Is the throne of the king Tutankhamun expression of the land of Egypt? - Does the throne of King Tutankhamun hold an Egyptian integral environmental system? - Can we through the environmental system reach determinants, in order to rely on, Designing furniture, to grant the same wealth and cultural exchange?
