The tomato crop is Lycopersico esculentum L. of the Solanaceae family. The considered world's first among the vegetable crops in terms of cultivated area annually. It is the third most important agricultural products after wheat and barley and the second most important vegetable crops after potatoes in Libya. The study aimed to isolate and identify the cause of tomato wilt disease its under greenhouse conditions. Four Fusarium oxysporum isolates were obtained from tomato roots and surrounding area growing under protected agricultural conditions at Janzour and Ein Zara in Tripoli- libay. The fungus were more frequent at Ein Zara area (37%), compared with Janzour (22%).

There are some groups who may get the risks of hospital waste disposal. The first group is the patients who come to hospital to get cure and care. It is the most vulnerable group. The second is hospital’s employees who have direct contact with the patients as main illness’s agents on doing their daily duties. The third group is the visitor or those who accompany the patients; their risk is big as well. The last group is the society, people who live near the hospital, even when the waste siposal is done inappropriately. It causes the decrease of environmental quality which leads to the decline of health quality in the area. Hence, hospital has a responsibility to manage the disposal process of waste correctly and appropriately by conducting sanitation programs in hospital. Jogja Hospital is a Government-owned Hospital run by the Government of city of Jogyakarta. In its daily activities, the hospital produces waste which, if not properly discharged or burned, may cause adverse effect on workers as well as the surrounding area. Jogja hospital has Incinerator, thus simplifying the management such waste. The waste management including the rules, procedures and policymaking need to be explored to investigate the process of waste management of Jogja hospital.

A new modification of Rb[Al(NH2)4] in space group C2/c, which differs from the known structural modification in the way the [Al(NH2)4]−-tetrahedra are arranged in the surrounding area of the rubidium cation, was obtained from ammonothermal synthesis at 673 K and 680 bar. The crystal structure was determined by Rietveld refinements and further investigated by infrared and Raman spectroscopy. Thermal gravimetric investigations indicate two decomposition steps up to 450 °C, which can be assigned to ammonia leaving the material while the sample liquefies. During the third and final step, volatile rubidium amide is released, leaving nano-scaled cubic AlN behind. Investigating differently aged samples implies decomposition and condensation of amidoaluminate ions already at ambient temperature, which is supported by refinements of single crystal X-ray diffraction data, revealing lower nitrogen amounts than expected. The observed single crystal also exhibits a significantly smaller volume than the reported structures, further supporting the decomposition–condensation mechanism.

Shape Quantification

Seed shape in species of the Cactaceae is described by comparison with geometric models. Three new groups of models are presented, two for symmetric seeds, and a third group for asymmetric seeds. The first two groups correspond, respectively, to superellipses and the combined equations of two semi-ellipses. The third group contains models derived from the representation of polar equations of Archimedean spirals that define the shape of asymmetric seeds in genera of different subfamilies. Some of the new models are geometric curves, while others are composed with a part resulting from the average silhouettes of seeds. The application of models to seed shape quantification permits the analysis of variation in seed populations, as well as the comparison of shape between species. The embryos of the Cactaceae are of the peripheral type, strongly curved and in contact with the inner surface of the seed coat. A relationship is found between seed elongation and the models, in which the genera with elongated seeds are represented by models with longer trajectories of the spiral. The analysis of seed shape opens new opportunities for taxonomy and allows quantification of seed shape in species of the Cactaceae.

Abstract Hollow fiber (HF) membranes with circular geometry, are used in many separation processes such as water and wastewater treatment. Since optimization of energy efficiency is important for wastewater treatment, the aim of this study was to investigate the effect of non-circular geometry of the inner surface of the HF on the separation performance. To this purpose, the HF bundle has been assumed as a double porous media having two porosities and permeabilities. Since these two parameters are defined by the geometry of the porous medium, any change in the geometry affects their values and the media performance. Therefore, in this study a mathematical modeling has been divided into five categories, including circular, oval, square, rectangular and triangular geometries, and their geometric properties have been calculated based on three different strategies. The results have been compared with the data obtained from literature and showed that the membrane inner surface to cross-section area ratio (a), axial permeability, and porosity in the inner region for the non-circular HF are larger than that of the circular HF and a increased 16%, 27%, 35% and 65% in ellipse, square, rectangle and triangle geometry, respectively, in comparison with the circle. Axial permeability increased 98%, 68%, 63%, and 26% for a triangle, rectangle, ellipse, and square respectively in the third strategy when compared to the circle. Due to 50% feed flow rate reduction, maximum transmembrane pressure (TMP) reduction was 85% related to the rectangular geometry in the first strategy and minimum was 55% corresponding to the triangle in the third strategy. As a increased up to 65%, TMP reduced by up to 200% and consequently energy consumption and operating costs of the system are decreased.

Third Dimension

This chapter scrutinizes the allusive potential of ornament and the two-dimensional paradigm that dominates ornament studies. Surveying the historiography of architecture-as-ornament, the chapter explores ornament’s relationship with the third dimension. In particular, it focuses on the potential for architectural motifs, especially arches and arcades, to confound two-dimensionality through the generation of fictive spaces that articulate and order form as well as surface. The chapter focuses first on the image of the arcade in various media and particularly on a group of inlaid metalwares with Christological scenes. Next, it moves to thirteenth-century Mosul and the surrounding area to explore the reciprocal relationship between plastic systems of three-dimensional ornament on buildings, metalwares, and a remarkable group of large architectonic earthenware water jars known as ḥabbs.

AbstractAs reported recently by the authors, the third and fourth antennomeres of the antennal club of the bark beetle Dendroctonus vitei Wood (Coleoptera: Curculionidae: Scolytinae) possess conoid sensilla clustered inside spherical or bulb-shaped invaginations of the cuticle that resemble geological pit craters. These structures are novel relative to other Dendroctonus Erichson species examined. The morphology and ultrastructure of different sensilla types on the antennal club and within the pit craters of D. vitei are herein described in detail with the aid of light, environmental scanning electron, and transmission electron microscopy. Five types of sensilla were found: fluted, basiconica type I, and trichodea types I, II, and III. The pit craters were composed of clusters of multiporous sensilla basiconica arising from the inner surface of the concavities, and the morphology and ultrasructure of these sensilla are consistent with an olfactory function. The presence of pit craters in the D. vitei on the anterior side of the antennal club is an diagnostic character for this species and an autapomorphy of great taxonomic importance within the Dendroctonus frontalis Zimmermann species complex.
