An east-west correlation profile through the upper Neogene succession north of Antwerp, based on cone penetration tests, reveals the architecture of the lower Pliocene Kattendijk Formation. It shows a basal incision of the Kattendijk Formation down to 20 m in Miocene sands and locally even Lower Oligocene clays. The incision is part of a much larger gully system in the region at the base of the Kattendijk Formation. The strongest gully incision is observed along the western profile, and coincides with increases in the thickness of the Kattendijk Formation from its typical four to six meters thickness in the east towards a maximum of 15 m in the west. Correlations show that this additional thickness represents a separate sequence of the Kattendijk Formation that first filled the deepest part of the gully prior to being transgressed and covered by the second sequence deposited in a larger gully system. Both sequences of the Kattendijk Formation have basal transgressive layers, and are lithologically identical. Initial, deep incision at the base of the Kattendijk Formation might have been the result of the constriction of early Pliocene tidal currents that invaded and expanded fluvial or estuarine gullies that had developed during the latest Miocene sea-level low. A similar mechanism had been proposed for the development of late Miocene gully system at the base of the Diest Formation further southeast in northern Belgium. As the wider area was transgressed and covered by the second sequence of the Kattendijk Formation, flow constriction ended, currents weakened and gully incisions were reduced in size.

Geological Map

The geology of the Oman Mountains, including the Jabal Akhdar and Saih Hatat domes, is extraordinarily well-exposed and diverse, spanning a geological record of more than 800 Ma. The area is blessed with first-class outcrops and is well known in the geological community for its ophiolite. The Oman Mountains have much more to offer; including, Neoproterozoic diamictites (“Snowball Earth”), fossil-rich Permo-Mesozoic carbonates and metamorphic rocks. The arid climate and deep incision of wadis allow for nearly complete rock exposure which can be investigated in all three dimensions. The diverse geology is also responsible for the breathtaking landscape. New roads and the nature of the friendly Omani people make fieldwork unforgettable.This Memoir provides a thorough state-of-the-art overview of the geology and tectonics of the Southeastern Oman Mountains, and is accompanied by an over-sized geological map and a correlation chart.

Introduction:  Skin is generally colonised by a wide range of microorganisms that could cause infection. Surgical site infection (SSI) requires evidence of clinical signs and symptoms of infection rather than microbiological evidence alone. SSIs generally affect the superficial tissues, but some more serious infections affect the deeper tissues or other parts of the body manipulated during the surgical procedure.About 5% of patients posted for surgery develop surgical site infections (SSIs), which may cause much morbidity and may sometimes mortality. Treatment of SSIs imposes a substantial financial burden on the health care system. Patients who develop SSI are more likely to spend 60% more time in an Intensive care unit (ICU), they are 5 times as likely to be readmitted and their mortality rate is twice of non-infected patient. But to great surprise 40-60% of these infections are preventable. Material and Methods: A total of 500 patients who had undergone surgical procedure at the teaching hospitalwere studied prospectively. A total of 464(92.8%) elective surgical patients and 36(7.2%) emergency surgical patients were included in the study.Patient information gathered from the data chart, treatment chart and from ward rounds in the hospital. All patients were followed up from the time of admission until the time of discharge and 30 days postoperatively to inspect the incidence of SSI. Wound infection was diagnosed. SSI diagnosed was divided into three categories: Superficial incision SSI, Deep incision SSI and Organ/space SSI. SSI is considered if an infection occurred within 30 days after the operation, if no implant is left in place SSI was considered. Results: In the present study 500 patients were included of which 464(92.8%) were elective surgical patients and 36(7.2%) were emergency surgical patients. Total SSI cases were 41 (8.2%) of which 29 (70.7%) were identified in elective surgery cases and 12 (29.3%) were observed in emergency surgery superficial incision SSI was most prevalent 25 (61%) followed by deep incisional SSI 11(26.8%) and then by organ/space SSI 5(12.2%).Mean age in elective surgery group was 52.4±7.48 and in emergency surgery group was 56.2± 6.78. In elective surgery group there were 296 (63.8%) male and 168 (36.2%) female. In emergency group there were 29 (80.6%) male and 7 (19.4%) female. Prophylactic antibiotics were given to 404 (87.1%) in elective surgery group and 30 (83.3%) in emergency surgery group. SSI rate observed in elective surgery group was 29/464 (6.25%) while in emergency surgery group was 12/36 (33.33%).BMI (Body mass index) in elective surgery group was 28.7 ±2.45and in emergency surgery group was 27.6 ± 2.89. Conclusion: higher incidence of SSI with increasing age of the patient.it was observed that to prevent SSI prophylactic antibiotics should be initiated within one hour before surgical incision.

В статье рассматривается возможность выделения наследственных признаков геодинамической обстановки и элементов структурно-вещественных комплексов, участвующих в геологическом развитии  Кавказа, на глубинных геоэлектрических и сейсмологических разрезах для создания геолого-геофизической моделей земной коры вдоль региональных профилей. Современные структурно-тектонические и структурно-вещественные комплексы восточной части Центрального Кавказа интерполируются с основными структурами консолидированной коры и низов коры. Обосновывается научный и практический интерес корреляционной увязки глубинных коровых и мантийных структур с месторождениями твердых полезных ископаемых и углеводородов, роль границы Мохоровичича в локализации месторождений. Субширотная структура реликтового рубца (геосутуры), уверенно выделяемая по минимумам напряженности полного вектора магнитного поля по структурно-вещественным элементам (олистостромы, офиолиты, микститы) представляется убедительным наследственным признаком субдукции. Реликтовый рубец представляется выполненным тектонизированным терригенным материалом, содержащим разного размера глыбы и блоки вулканогенно-осадочных пород и ремобилизованные олистостромы пород офиолитового комплекса, что является формационным признаком геодинамической обстановки, фиксируемой в развитии структуры Кавказа. The article deals with the possibility of identifying hereditary features of the geodynamic situation and elements of structural and material complexes involved in the geological development of the Caucasus, in deep geoelectric and seismological sections to create geological and geophysical models of the earth's crust along the regional profiles. Modern structural-tectonic and structural-material complexes of the Eastern part of the Central Caucasus are interpolated with the main structures of the consolidated crust and the lower crust. The scientific and practical interest of correlation linking of deep crustal and mantle structures with deposits of solid minerals and hydrocarbons, the role of the boundary of Mokhorovichych in the localization of deposits is substantiated. Latitudinal structure of the relic scar (geostructure), confidently allocated to the minimum of the tension of magnetic field full vector on structural-material elements (olistostromes, ophiolites, mixtite) persuasive inherited character of subduction. Relict scar is represented by tectonized terrigenous material containing different size blocks and blocks of volcanogenic-sedimentary rocks and remobilized olistostromes of rocks of the ophiolite complex, which is a formative sign of geodynamic situation, recorded in the development of the structure of the Caucasus.

ABSTRACT Aim To simplify and enhance safety in the generation of a stabilizing intracorneal scar by circular keratotomy (CKT). A femtosecond laser was used to perform individually sized intraparenchymal cuts. Materials and methods As equipped, the Ziemer Z6 femto-second laser cuts a 400-µm-deep incision with a diameter of 7.0 mm around the optical axis. The epithelium, Bowmann's membrane, the internal borders of Descemet's membrane, and the endothelium are not affected. The 3-, 6-, and 12-month postoperative values were compared with the 1-month postoperative keratometric readings and astigmatism. The preoperative best corrected visual acuity (BCVA) with glasses was compared with the values found at the same time points as noted above. Results Statistical evaluation indicated that keratometry within ±1.5D remained in 96.6, 93.1, and 96.6% of cases at the 3-, 6-, and 12-month time points respectively. Astigmatism was stable at the same time points in 100, 95.8, and 92.3%. The BCVA improved in 12 cases throughout the first post-operative year (48%, n = 25); however, 11 cases did not change (44%) and 2 cases lost at least one line (8.0%). Conclusion Femto CKT halts the progression of keratoconus for at least 1 year in 96.6% of cases. This treatment provides keratometric and refractive stability for over 1 year. This result, in conjunction with the significant improvement in BCVA, demonstrates the potential of this method for patients with stage I and II keratoconus.

♂♀. Derm black, with uniform dense grey scaling that has a coppery reflection.Head separated from rostrum by a narrow bisinuate stria; frons depressed below the level of the eyes and separated from them by a deep incision on each side, obliquely striolate and with a deep median sulcus; eyes moderately convex, extended sharply backwards for about one-third of their length, the orbit not projecting on the hind margin. Rostrum very slightly longer than its basal width, widest at base, gradually narrowing for two-thirds its length and thence more rapidly; dorsum broadly depressed, with longitudinally confluent punctures and a fine median carina. Antennae piceous; scape slightly exceeding hind margin of eye; funicle with joint 1 nearly twice as long as 2,3–7 subequal, about as long as broad and slightly widening distally. Prothorax nearly twice as broad as long, unusually flat, being only gently convex transversely, widest at the strongly arcuate base, the angles of which project laterally, with the sides almost straight and rapidly converging anteriorly, the apical margin being deeply sinuate on each side behind the eyes; dorsum flat longitudinally in the middle, densely squamose, each scale covering a minute granule. Elytra ovate, broader in ♀, widely sinuate at base, which is marginate, with the lateral angles projecting outwards and forwards, and the sides sinuate behind the angles; the dorsal outline moderately convex, sloping at the base; the shallow striae containing close deep punctures, which show through the scaling though partly covered and disappear behind, where the striae become deeper; intervals almost flat, with minute inconspicuous recumbent setae. Legs piceous, with dense concolorous scaling and their lower edges with a fringe of stiff erect setae; front tibiae compressed, with the outer edge carinate and the external apical angle produced laterally, the spines on the apical margin much reduced; hind tibiae with the inner face flattened and sinuate on the apical half, the corbels bare and ascending the dorsal edge more than usual, with the upper end angulate. Venter squamose laterally, but clothed elsewhere with dense stiff suberect setae.
