    Friday prayer is an essential congregational practice in Muslim communities. To prepare for Friday prayer, worshippers groom and cleanse themselves ahead of time, according to Islamic ablution rituals, and dress in their best attire. Eadah is a collection of contemporary tools designed to facilitate the pre-prayer cleansing ritual, inspired by traditional Qatari remedies and wellness practices. The tools reflect three balanced considerations: touch, meditative making, and cultural preservation. They are used to prepare natural ingredients through mindful making that produce remedies with stimulating scents and sensations through touch. An emphasis on cultural preservation differentiates Eadah from other tools offered by the cosmetics industry. Eadah benefits from an infusion of Qatari wisdom and multi-generational knowledge, combining local wellness practices with novel tools

    Sheraoh island is the most remote among Qatari islands, nearly 73.5 km south-eastern of the mainland of the peninsula. In March 2010, a preliminary general survey of the species was conducted. Observations were made partly by wading and snorkeling in the intertidal zone and partly by surveying the inland habitats. In total the 31 species were recorded, 4 species of halophyte plants: Halopeplis perfoliata, Suaeda vermiculata, Salsola baryosoma and Zygophyllum qatarense, one unexpected terrestrial mammal: the cape hare Lepus capensis, 2 species of visiting birds: Motacilla flava and Anthus campestus and one species of sea bird. Phalacrocorax nigrogularis, one dolphin species: Sousa chinensis. The largest richness was found in the marine habitats, 3 species of sea weeds: Colpomenia sinusa, Padina boergesenii and Sargassum boveanum, 3 species of corals: Anomastraea irregularis, Platygyra lamellina and Porites harrisoni, 2 species of nudibranchs: Chromodoris cazae and Chromodoris sp. (unidentified)., 4 crab species: Hermit crab (unidentified), Etisus laevimanus, Grapsus albolineatus and Lambrus prensor, 4 species of echinoderms: Pentacentral mammillatus, Ophiothela venusta, Diadema setosum and Echinometra mathaei, 5 species of bony fish: Doryrhamphus sp. (larva), Cypserulus oligolepis, Lethrinus nebulosus, Cephalopholis miniatus and Hemiramphus marginatus, one species of sea snakes: Hydrophis sp. The most striking result is to collect an unknown nudibranch species and to report the cape hare which is unexpected inhabitant. All figures of this study are published for the first time in Qatar.Qatar Universit

    Harmful Algal Bloom species are ubiquitous and their blooms occur in the Arabian Gulf. In this study, two cruises were performed in 2012 and 2013 to collect phytoplankton samples from 4 sites in the Arabian Gulf. Toxin analyses of phytoplankton samples for 32 algal toxins from 5 different toxin groups were conducted on the samples using both enzyme linked immunosorbent assay (ELISA) and liquid chromatography?tandem mass spectrometry (LC-MS/MS). Results demonstrated, for the first time, the presence of paralytic shellfish toxins (PSTs), diarrhetic shellfish toxin (DST), amnesic shellfish toxin (AST), cyclic imines (CIs) and polyether-lactone toxins in freeze-dried phytoplankton samples. Four Vulcanodinium rugosum cultures were established from field samples and these proved to contain between 603 and 981 ng pinnatoxin (PnTx) H per mg dry weight in addition to being positive for portimine. These strains from Qatar clustered with strains from Japan and Florida based on large subunit rRNA and rRNA internal transcribed spacer gene sequencesScopu

    The phospholipid fatty acid contents of six Haplosclerida sponges collected along Qatari ;ts, Arabian Gulf, were identified by coupling GC-MS experiments. More than hundred of rated and unsaturated fatty acids have been identified. Strong variations were observed for both rated and unsaturated fatty acids within the three studied genera: Callyspongia, Gelliodes, and tates. A new dienoic fatty acid: 14-Me-5,9-17:2 and several rare or uncommon fatty acids were tified from GC/MS coupling experiments. Striking differences between both Gelliodes species e observed for fatty acids belonging to the n-7 family with total content ranging from 0 to 18%.تم التعرف على الأحماض الدهنية الفسفوليبيدية لستة أنواع من اسفنج هالوسكاليدا الذي ينمو في قطر باستخدام كروماتوجرافيا الغاز وطيف الكتلة. وتم فصل أكثر من مائة حمض دهني مشبع وغير مشبع. وأوضحت الدراسة وجود فارق كبير في بنية الأحماض الدهنية المشبعة وغير المشبعة بين ثلاثة فصائل هي: كاليسبونجيا و جليوديس ونيفاتس كما تم التعرف على حمض دايانويك جديد 14-Me-5, 9-7 وبعض الأحماض الدهنية النادرة. كما أن الدراسة أوضحت اختلاف واضح في مكونات الأحماض الدهنية التي تنتمي إلى عائلة n-7 لأسفنج جليوديس حيث تراوحت نسبتها من صفر إلى 18%
