Bowl Inversion of Surface-Adsorbed Sumanene
No full textBowl-shaped π-conjugated compounds offer the possibility to study curvature-dependent host–guest interactions and chemical reactivity in ideal model systems. For surface-adsorbed π bowls, however, only conformations with the bowl opening pointing away from the surface have been observed so far. Here we show for sumanene on Ag(111) that both bowl-up and bowl-down conformations can be stabilized. Analysis of the molecular layer as a function of coverage reveals an unprecedented structural phase transition involving a bowl inversion of one-third of the molecules. On the basis of scanning tunneling microscopy (STM) and complementary atomistic simulations, we develop a model that describes the observed phase transition in terms of a subtle interplay between inversion-dependent adsorption energies and intermolecular interactions. In addition, we explore the coexisting bowl-up and -down conformations with respect to host–guest binding of methane. STM reveals a clear energetic preference for methane binding to the concave face of sumanene

Feasibility of groundwater recharge dam projects in arid environments
No full textA new method for determining feasibility and prioritizing investments for agricultural and domestic recharge dams in arid regions is developed and presented. The method is based on identifying the factors affecting the decision making process and evaluating these factors, followed by determining the indices in a GIS-aided environment. Evaluated parameters include results from field surveys and site visits, land cover and soils data, precipitation data, runoff data and modeling, number of beneficiaries, domestic irrigation demand, reservoir objectives, demography, reservoirs yield and reliability, dam structures, construction costs, and operation and maintenance costs. Results of a case study on more than eighty proposed dams indicate that assessment of reliability, annualized cost-demand satisfied and yield is crucial prior to investment decision making in arid areas. Irrigation demand is the major influencing parameter on yield and reliability of recharge dams, even when only 3. months of the demand were included. Reliability of the proposed reservoirs as related to their standardized size and net inflow was found to increase with increasing yield. High priority dams were less than 4percent of the total, and less priority dams amounted to 23percent, with the remaining found to be not feasible. The results of this methodology and its application has proved effective in guiding stakeholders for defining most favorable sites for preliminary and detailed design studies and commissioning. © 2014.Adiat KAN, 2013, PURE APPL GEOPHYS, V170, P453, DOI 10.1007-s00024-012-0501-9; ALMUTTAIR FF, 1994, J WATER RES PL-ASCE, V120, P749, DOI 10.1061-(ASCE)0733-9496(1994)120:6(749); Al-Qurashi A, 2008, J HYDROL, V355, P91, DOI 10.1016-j.jhydrol.2008.03.022; Al-Turbak Abdulaziz S., 1989, INT J WATER RESOUR D, V5, P119, DOI 10.1080-07900628908722423; Andersen GR, 2001, J GEOTECH GEOENVIRON, V127, P335, DOI 10.1061-(ASCE)1090-0241(2001)127:4(335); Bartholome E, 2005, INT J REMOTE SENS, V26, P1959, DOI 10.1080-01431160412331291297; Chouinard L., 1996, J INFRASTRUCT SYST, DOI 10. 1061-(ASCE) 1076-0342(1996) 2: 1(23), 23-29; Department of Land Management, 1985, GEN SOIL MAP SAUD AR; Directorate of Projects Implementation, 2006, DAMS SAUD AR; Haimerl G., 2004, GROUNDWATER RECHARGE; Hydrology Division, 1983, HYDR PUBL, V98; Jarvis A, 2008, HOLE FILLED SEAMLESS; Koustoyiannis D., 2004, ENCY WATER; Lange J, 1999, WATER RESOUR RES, V35, P2161, DOI 10.1029-1999WR900038; Maidment D.R., 2002, ARC HYDRO GIS WATER; McIntyre N, 2009, ENVIRON MODELL SOFTW, V24, P726, DOI 10.1016-j.envsoft.2008.11.001; MICHAUD J, 1994, WATER RESOUR RES, V30, P593, DOI 10.1029-93WR03218; NASA, 2008, UMD LANDC CLASS; Natural Resources Conservation Service, 1997, NAT ENG HDB 630; PEGRAM GGS, 1980, J HYDROL, V47, P269, DOI 10.1016-0022-1694(80)90097-9; PILGRIM DH, 1988, HYDROLOG SCI J, V33, P379, DOI 10.1080-02626668809491261; Rijsberman FR, 2006, AGR WATER MANAGE, V80, P5, DOI 10.1016-j.agwat.2005.07.001; Saudi Geological Survey, 2008, HOW TO ORD; Shovic H.F., 2010, WATERSHED MANAGEMENT, P1094; Tizro A.T., 2007, J APPL SCI, V7; UNEP, 1997, WORLD ATLAS DESERTIF; U.S. Weather Bureau, 1958, TP 29 RAINF INT FREQ; Zakhem Boulos Abou, 2012, Hydrological Processes, V26, DOI 10.1002-hyp.84460
Penggunaan tasybih dan isti'arah dalam cerpen Arab dan Melayu : satu perbandingan / Nurul Ashiqin binti Jaafar
No full textThis dissertation entitled "Comparison Tasybih and Isti‘arah in Arabic and Malay Stories", discuss about comparison study between Arabic and Malay stories. The aim of this research is to introduce of the styles of tasybih and isti‘arah (style of comparative language) in Arab and Malay short stories. Tasybih and isti‘arah is a form of Arab rhetoric that led to the study and teaching of effective communication through the use of proper language style according to language experts. It not only describes the structure of a brief, but included definitions and examples as well as comparisons between tasybih and isti‘arah in Arabic and Malay. This dissertation study compares the language metaphor in Arabic and Malay short stories by two eminent authors of Naguib Mahfouz and Anwar Ridhwan. The aim of the study aspect of language styles in Arabic and Malay as well as examine the similarities and differences.
In addition, two authors sustainably equity selection from Egypt and Malaysia is based on achievement, strengths and tendencies in their respective fields of writing prose, especially short stories. Both materials also never made a comparative study or analysis of text-Arabic Malay researchers earlier. For Naguib Mahfouz, in his selected short stories entitled Nisf Yaum (Separuh Hari) and Al-Hawi Khatafa at-Tabaq (Tukang Silap Mata Melarikan Pingganku). Meanwhile, Anwar Ridhwan, in his selected short story entitled “Perjalanan Terakhir”. The main finding of this study is the style of language used by Naguib Mahfouz in his works mostly direct the view to use tasybih and isti‘arah in a parable in his short stories and the style of language used by Anwar Ridhwan in his writing more overlap or are indirect. At the end, the author will discuss the conclusion of the study, and some suggestions that are considered should be brought to attention of certain parties. Hopefully, this study will bring benefits to all
Genetic diversity analysis and DNA fingerprinting of tomato breeding lines using SSR markers
No full textSaabunud / Received 01.04.2021 ; Aktsepteeritud / Accepted 04.06.2021 ; Avaldatud veebis / Published online 04.06.2021 ; Vastutav autor / Corresponding author: Ghassan Jaafar Hamd [email protected] is a need to expand the information on genetic
relationships between tomato (Solanum lycopersicum L.) lines to improve
hybridization breeding. The genetic diversity and relationships among 24
tomato lines were evaluated by simple sequence repeat (SSR) markers. A
total of 65 bands were generated with 15 SSR primers, of which 64 bands
were polymorphic. The mean polymorphic information content was 0.356.
There was a high degree of polymorphism between tomato cultivars. The
mean marker index and heterozygosity were 0.045 and 0.454, respectively.
Cluster analysis grouped cultivars into 6 main clusters. The cvs. Mo. H. P,
'C. C. Orange', and 'Marb' had the greatest genetic distance from other
cultivars and is suitable for hybridization to achieve maximum variability
for selection in segregating populations. The data can be used to select
appropriate parents in tomato hybridization breeding

Orbitopterional Approach for the Resection of a Suprasellar Craniopharyngioma: Adapting the Strategy to the Microsurgical and Pathologic Anatomy
No full text
Objectives To describe the orbitopterional approach for the resection of a suprasellar craniopharyngioma with emphasis on the microsurgical and pathological anatomy of such lesions.
Design After completing the orbitopterional craniotomy in one piece including a supraorbital ridge osteotomy, the Sylvian fissure was split in a distal to proximal direction. The ipsilateral optic nerve and internal carotid artery were identified. Establishing a corridor to the tumor through both the opticocarotid and optic cisterns allowed for a wide angle of attack. Using both corridors, a microsurgical gross total resection was achieved. A radical resection required transection of the stalk at the level of the hypothalamus. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy. Understanding the cisternal and topographic relationships of the optic nerve, optic chiasm, and internal carotid artery is critical to achieving gross total resection while preserving normal anatomy.
Participants The surgery was performed by the senior author assisted by Dr. Jaafar Basma. The video was edited by Dr. Vincent Nguyen.
Outcome Measures Outcome was assessed with extent of resection and postoperative visual function.
Results A gross total resection of the tumor was achieved. The patient had resolution of her bitemporal hemianopsia. She had diabetes insipidus with normal anterior pituitary function.
Conclusions Understanding the microsurgical anatomy of the suprasellar region and the pathological anatomy of craniopharyngiomas is necessary to achieve a good resection of these tumors. The orbitopterional approach provides the appropriate access for such endeavor.The link to the video can be found at: https://youtu.be/Be6dtYIGqfs.</jats:p

No full textPraise and Gratitude be to Allah, Lord of the all worlds. And prayers and peace and greetings upon the most noble of the prophets and messengers, our master Muhammad and his family and companions, then after: This thesis concerned with grammatical and morphological guidance of the uniqueness of one of the famous ten Quran readers, who is the famous reciter, and the world's subtle, Abu Jaafar al madani, Yazid ibn Qaqaa, who died in 128 Hijri, he was Sheikh of the famous Quran reader, Nafee Al madani. I adopted in collecting the material of this thesis from a unique book, that take care in collecting the material of this Quran reader from a rout of Abu Alharith Isaa Ibn Wardan, was done by Abdul Majeed Ibn Shaddad al- Tamimi, a scientist from the sixth Hijri's century, and the title of his book (Choice of Abu Jaafar al madani). This thesis titled (Grammatical and Morphological guidance of what Abu Jaafar Al-madani was distinguished from the faces of Quran readings through the book: choice of Abu Jaafar by Ibn Shaddad). I confined to guide the uniqueness of this Quran reader only, because what the reader agreed with the readings books, which is concerned in the guidance of the Quran's seven reading methods, was guided. like the book of Alhuja of seven Quran readers by Ibn Fares who died in 377 hijri, and Huja of the Quran readings methods by Ibn Zangala who died in 403 hijri and more other. This thesis plan includes four chapters, there are an investigations and demands under each chapter , The first chapter is about Quran readings methods ,it's arise ,the number of readers and the narrators. The second chapter includes Abu Jaafar Almadani's translation, properties of his reading method, and a brief introduction of the book and the author. The third chapter is for the grammatical guidance of what Abu Jaafar Almadani is distinguished, which includes nominatives, debutant and news and their scribes, almansobat, prepositional, and identifiers, which contains pronouns and gentives. The fourth chapter was specified of morphological guidance for subjects by which Abu Jaafar was distinguished, it is include: Routing of verbs, past, present, routing of origins and derivatives, participle and past participle, plurals and absent pronouns. I ended my thesis by results had been concluded
