Analysis of Seismic Dynamic Response of Tunnel in Karst Areas

Based on soil-structure interaction model, the seismic dynamic response of tunnel in karst areas were performed by using viscous-spring artificial boundary and time history analysis method. In combination with the Menglian tunnel engineering on the Bao-Teng Highway in Yunnan, in different sizes and sites karst caves conditions, the dynamic responses of displacement and internal force on control points of the tunnel structure were obtained. The results show that comparatively large interal forces, under the high-intensity earthquake conditions, will appear on the side wall of the tunnel which through karst areas, less ones on arch crown and inverted arch parts, and the differential displacements of arch crown reach to the maximum. When the karst caves are located in the side of the tunnel, it make the seismic dynamic response get more large, which make the surrounding rock must be strengthened treatment. The results provide useful reference for the aseismatic design of tunnel.

Clinical application of modified reduction plasty of malar and zygoma

Objective To introduce a new method for correcting prominent malar complex deformity. Methods Through an intraoral incision, the highest area of zygomatic body marked preoperatively was grinded. Then an L shape incomplete osteotomy of the zygomatic body was performed with a reciprocating saw, and a complete osteotomy just 1 cm anterior to the articular tubercle of the zygomatic arch was made. Light pressure on the posterior part of the arch produced a greenstick fracture of the anterior osteotomy site, resulting in posterior-inward repositioning of the malar complex. Internal fixation was unnecessary. Results Operative procedures for reductive malar complex plasty were performed in 650 cases, which included 60 males and 590 females whose age ranged from 19 to 39 years.Incisions of all cases healed well. One case had maxillary sinusitis 2 weeks postoperatively, and recovered after 1 week by using antibiotics and drainage. There was 1 case with skin necrosis about 1 cm in diameter in the area of zygomatic body because of local liposuction, and the wound was healed by changing dressing. The forehead wrinkle of one side had disappeared in 1 case 1 week postoperatively, but had recovered 2 weeks later. Postoperative follow-up for 2-24 months showed satisfactory results.Conclusions This modified method has many advantages, such as simplicity, without internal fixation, short operation and recovery time, and little complications. The authors conclude that this technique is an effective and safe method of reduction malarplasty. Key words: Prominent zygoma; Redution malarplasty; Osteotomy

Analysis of Mechanical Characteristics of Site Experiment on Supporting Structure in Gypsum Breccia Tunnel

Gypsum breccia is a kind of soft rock-hard soil, and its component is complex. It has poor cementation, low intensity, strong water reaction, slight expansibility and corrosion. During the tunnel construction of gypsum breccia stratum, the mechanical characteristic of supporting structure is very complex. In order to ensure the safety, reasonability and economy of tunnel support system, it is important to acquire the information on displacement and stress of surrounding rock and support system. Two test sections are selected to monitor. Based on the measured data, the distribution characteristics and the time variation law of different kinds of support in gypsum breccia stratum are studied, including surrounding rock pressure, axial force of rock bolt, support pressure and stress. Such conclusions can be got: When strengthened lining (16# I-steel) of the V-grade surrounding rock used, support system performs well; but the stiffness of primary support is not enough if grillage lining is used. Growth of surrounding pressure is for a long time, which shows that the rock mass has Flow characteristics. Especially the surrounding rock pressure increases continuously. The spatial distribution is random, and the value is large. The stiffness of support system should be strengthened. Most blots at the waist arch are compressive. Bolts at the foot arch and sidewall are under tension. The maximum is nearly 124kN. Contact pressure between primary support and secondary lining at the sidewall is higher than that at arch parts. Steel frame stress comes up to 80% of the maximum within 20 days. Excavation of invert has great influences on stress state of surrounding rock and support system.

Arterial Injury Complicating Subclavian Central Venous Catheter Insertion

n i a a g n c INADEQUATE PLACEMENT of a subclavian venous catheter in the subclavian artery is a well-known complication.1,2 Three cases of accidental arterial puncture occurred with the implantation of subclavian venous catheters, 2 of which involved the subclavian artery leading to percutaneous treatment; and the other involved the aortic arch, resulting in surgical management, are described.

Nonalimentary tooth use in the neolithic population of the Lengyel culture in central Poland (4600–4000 BC)

One hundred and four skeletons of adult individuals representing Neolithic populations of the Brześć Kujawski group of the Lengyel Culture (Kuyavia, central Poland, 4600-4000 BC) were analyzed with regard to evidence of nonalimentary tooth use, periapical lesions and antemortem tooth loss (AMTL). Instances of nonalimentary behaviors were found in 47.1% of females and 27.5% of males. Females were primarily characterized by occlusal grooves on the incisors and canines, most probably resulting from yarn production or weaving. The most frequent defect in males was severe tooth wear extending from the incisors to first molars, caused by some hard-to-identify nonalimentary activities. Occlusal grooves were also found in males, but their morphology indicates processing of some coarser material. The occupational nature of the tooth defects has been confirmed by archaeological data. The only two burials with grave goods indicative of craft specialization at the sites studied contain the remains of individuals with marks of nonalimentary tooth use. Moreover, the sites provide unequivocal evidence of weaving and basketry production in the form of loom weights and imprints of cloth and mats. Periapical lesions have been found in 40.4% of males and 35.6% of females, and AMTL in 32.1% of males and 36.7% of females. Individuals with evidence of nonalimentary tooth wear are characterized both by a higher incidence of these lesions in general, and by their more frequent location in the anterior part of the alveolar arch.

Maxillary segmental distraction in children with unilateral clefts of lip, palate, and alveolus

Alveolar clefts are commonly closed by a bone grafting procedure. In cases of wide clefts the deficiency of soft tissue in the cleft area may lead to wound dehiscence and loss of the bony graft. Segmental maxillary bony transfer has been mentioned to be useful in such cases. Standard distraction devices allow unidirectional movement of the transported segment. Ideally the distraction should strictly follow the dental arch. The aim of this study was to analyze distraction devices that were adapted to the individual clinical situation of the patients. The goal was to achieve a distraction strictly parallel to the dental arch. Six children with unilateral clefts of lip, palate, and alveolus between 12 and 13 years of age were included in the study. The width of the cleft was between 7 and 19 mm. Dental cast models were used to manufacture individual distraction devices that should allow a segmental bony transport strictly parallel to the dental arch. Segmental osteotomy was performed under general anesthesia. Distraction was started 5 days after surgery. All distracters were tooth fixed but supported by palatal inserted orthodontic miniscrews. In all patients, a closure of the alveolar cleft was achieved. Two patients required additional bone grafting after the distraction procedure. The distraction was strictly parallel to the dental arch in all cases. In 1 case a slight cranial displacement of the transported maxillary segment could be noticed, leading to minor modifications of the following distractors. Distraction osteogenesis is a proper method to close wide alveolar clefts. Linear segmental transport is required in the posterior part of the dental arch, whereas in the frontal part the bony transport should run strictly parallel to the dental arch. An exact guided segmental transport may reduce the postoperative orthodontic complexity.

Reduction Malarplasty with Small Preauricular Incision

Sir: Zygoma reduction surgery is performed with many methods on Asian patients. We insert an osteotome through a small preauricular incised part, fracture the zygomatic arch to the inside, and shave the body of the zygoma with a shaver. We think this approach to zygoma reduction surgery is safe and effective and thus wanted to report our findings. We performed zygoma reduction surgery on 1446 patients from March of 2003 to December of 2009. We determined which patients needed surgery based on medical photographs and radiographs before surgery, and performed surgery on 117 male patients and 1329 female patients. The average age of the male patients was 27.5 years and that of the female patients was 28.5 years. The average observation period after surgery was 6.4 months. We compared the medical photographs and radiographs before surgery and after surgery to show the results. Under general anesthesia, we made an incision 1 cm ahead of the tragus and then made an incision on the periosteum. We continued the dissection through the zygomatic arch through the subperiosteal level. Then, we fractured the forepart of the tubercle of the zygomatic arch using an osteotome, fractured the zygomaticotemporal suture and intrafractured the arch, and pushed it in while the inner periosteum was still attached (Fig. 1). We inserted a cylinder guide into the incision site on the forepart of the tragus and also placed a rasper to shave the prominent zygomatic body. To maintain the symmetry of both zygomas, we constantly watched and checked it by touching it with our fingers from the outside. After finishing the shaving, we trimmed up the tubercle to avoid step-off, which is a back part of the fractured arch, with a rasper that has a smaller tip. After we checked for bleeding, we deterged and sutured the part. For 3 days after surgery, we dressed it with elastic bandage and tape, applying pressure.Fig. 1.: 1 and 2, Sites for the osteotome; 3, site for shaving.For every patient, the zygoma was effectively reduced and satisfaction was achieved regarding aesthetic outcome. Eighteen patients reported that they were not satisfied, and nine patients reported asymmetry. However, all of the patients were satisfied after the second operation. There was no second operation performed resulting from infection or bleeding (Fig. 2).Fig. 2.: (Left) Preoperative view of 27-year-old woman with malar prominence. (Right) Postoperative view after reduction malarplasty.In 1983, Onizuka et al. introduced zygoma reduction surgery by intraoral incision.1 Since then, other ways of performing zygoma reduction surgery have been introduced by many other surgeons.2–5 We do not approach by the intraoral route. Because there is only little tissue incision and dissection, swelling, tissue damage, and bleeding hardly occur and do not give discomfort while eating. Because fracture of the body is not performed, drooping is rare. The technique uses only a preauricular incision of 1 cm so that no large scar is left. The substance that was used for fixing the arch is not needed, and there is no substance found on radiographs; as a result, we are pleased to introduce this new way, which minimized side effects.

Late Cenozoic geological development of the south Vøring margin, mid-Norway

Late Cenozoic seismic stratigraphy of the Vøring continental margin has been studied in detail, with emphasis on the geological development of the Naust Formation deposited during the last 3 million years. The Kai Formation (15–3 Ma) comprises mainly biogenic ooze deposited in the Møre and Vøring Basins. In Naust time, there was a marked increase in supply of sediments from the inner shelf areas and the western part of the Scandinavian mountain range, and glaciers expanded to the shelf and reached the shelf edge several times during the last 1.5–2 million years. During early to mid Naust time the shelf was widened by westerly prograding sediment units, but for a long period the shallowest part of the Helland-Hansen Arch (HHA) formed a barrier preventing glacially derived debris from being distributed farther west. West of the HHA, mainly stratified marine and glacimarine sediments were deposited. A substantial part of these sediments were transported by the north-flowing Norwegian Atlantic Current, which redistributed suspended particles from ice streams, rivers, coastal erosion and seabed winnowing. After burial of the crest of the HHA at c. 0.5 Ma, glacial debris and slide deposits were also deposited west of this high. In the north, massive units of glacial debris were distributed beyond the crest of the HHA, also in mid Naust time, thinning westwards and interfingering with fine-grained sediments on the lower slope. The Sklinnadjupet Slide, inferred to be c. 250,000 years old, corresponds in age with an earlier huge slide in the Storegga area. An elongated area of uneven seabed topography previously interpreted as diapirs (Vigrid diapirs) on the slope west of the HHA is shown to be formed by ooze eruption from the crest of the arch and submarine sliding.

How does occipitalization influence the dimensions of the cranium?

To describe occipitalization on human dry skulls and to compare craniofacial morphology including the posterior cranial fossa in skulls with occipitalization and in skulls without occipitalization and with normal craniofacial morphology (controls). A total of 29 skulls were selected from the Björk collection. Nine had occipitalization of atlas. Twenty had no dentoalveolar or craniofacial anomalies, and no occipitalization was visible on the skulls (controls). The ages of the skulls were between adolescence and adulthood. Visual assessments to describe the occipitalization pattern, direct measurements to measure the foramen magnum dimensions and cephalometric radiographic analyses to describe the craniofacial morphology. New variables were determined to describe the posterior cranial fossa. Of the skulls with occipitalization, 67% had complete and 33% had partial occipitalization. In the posterior part of the neural arch, 44% had a cleft. Occipitalization was significantly associated with a small foramen magnum (p < 0.01; p < 0.001) and deviant shape of the posterior cranial fossa (p < 0.05). The craniofacial morphology in the vertical and sagittal dimensions including the cranial base angle was normal in skulls with occipitalization, which indicates that occipitalization is associated with deviant morphology of the surrounding bony structures but not with deviations in the craniofacial morphology in general. The results of this study are important for the diagnosis of occipitalization on 2D radiographs.

Diagnosis of aortic coarctation combined with hypoplastic aortic arch by echocardiography

Objective To study the diagnosis accuracy and features of echocardiography on aortic coarctation combined with hypoplastic aortic arch. Methods The echocardiographic characteristics of seven patients who were diagnosed as aortic coarctation combined with hypoplastic aortic arch were analyzed and compared with results of cardiac catheterization, CT scan and operation. The diagnostic features of echocardiography were summarized. Results Besides the echocardiographic characteristics of aortic coarctation,other specific echocardiographic characteristics of hypoplastic aortic arch were:distinct stenoses of transverse and decsending part of aortic arch were visualized in supra-sternal long-axis view; the range of hypoplastic part started from innominate artery beginning or left common carotid artery beginning; the ratio of diameter of hypoplastic aortic arch over that of descending aorta at diaphragm was less than 0. 5; the blood flow speed detected by Doppler at the site of aortic coarctation was in the normal range. The echocardiographic characteristics of the aortic coarctation combined with hypoplastic aortic arch were correspondent to the results of cardiac catheterization, CT scan and operation results. Conclusions There is high accuracy of echocardiography in diagnosis of aortic coarctation combined with hypoplastic aortic arch. Hypoplastic aortic arch should be paid more attention in diagnosis of aortic coarctation. Key words: Echocardiography; Aortic coarctation; Hypoplastic aortic arch

Steatite icon with the Deposition at the monastery of Iveron on Mount Athos

This paper deals with a steatite icon of the Deposition, which is enshrined in the sacristy of Iveron monastery. The icon consists of two parts, one rectangular of light grey-greenish colour, with a smooth surface, and one arched of a darker colouring, porous texture and a rougher surface. The rectangular, older part of the icon is a fragment of a twelfth century icon from which the lower left angle and fragments of the right and upper side are lost. The fracture of this twelfth century icon led to its restitution which took place in the fourteenth century (the arched part), as it appears by the stylistic data and the inscriptions. At the same time the icon was embedded in the wooden panel.

Asymmetric Facial Growth and Deviated Nose

Deviated nose correction is difficult and constitutes a very different issue from septal deviation. When correcting this deformity, traces of asymmetry can be detected. The authors demonstrate facial asymmetry accompanying deviated noses, and such asymmetry is usually ignored by surgeons who typically concentrate only on nose deformities.A total of 5822 pre- and postrhinoplasty photographs related to 547 women and 124 men were reviewed. Out of the total population, the following 3 groups were selected: group A, gross nose and face asymmetry; group B, nose asymmetry with no facial deformity; group C, facial asymmetry with straight nose. Different measurements were applied to the selected photos, presented in . These included measurement from the lateral canthi to the lateral mouth corners (D1) and from the midface to each most lateral part of the zygomatic arch (D2). Measurements from one side were compared with those from the contralateral side to identify true anatomic differences, as presented in .(Table is included in full-text article.)(Figure is included in full-text article.)There was a significant difference in the nose and face deformity group, as evidenced by a meaningful difference in both the D1 and D2 measurements.We report a significant growth retardation of the midface and orbit on the concave side of the nose. This impediment may serve as the etiology for many asymmetries of the face and nose.

Regional characteristics of gene expression in the brain of the rhesus monkey

An M7.9 earthquake occurred on 30 May 2015 at an unusual depth of 680 km downward and away from the well-defined Wadati–Benioff (WB) zone of the southern Bonin arc. To the north (northern Bonin), the subducted slab is stagnant above the upper–lower mantle boundary at 660-km depth, where the WB zone bends forward to sub-horizontal. To the south (northern Mariana), it penetrates the boundary, where the WB zone extends near-vertically down to the boundary. Thus, the southern Bonin slab can be regarded as being in a transitional state from slab stagnation to penetration. The transition is shown to happen rapidly within the northern half of the southern Bonin slab where the heel part of the shoe-like configured stagnant slab hits the significantly depressed 660-km discontinuity. The mainshock and aftershocks took place in this heel part where they are sub-vertically aligned in approximate parallel to their maximum compressional axes. Here, the dips of the compressional axes of WB zone earthquakes change rapidly across the thickness of the slab from the eastern to western side and along the strike of the slab from the northern to southern side, suggesting rapid switching of the downdip compression axis in the shoe-shaped slab. Elastic deformation associated with the WB zone seismicity is calculated by viewing it as an integral part of the slab deformation process. With this deformation, the heel part is deepened relative to the arch part and is compressed sub-vertically and stretched sub-horizontally, a tendency consistent with the idea of progressive decent of the heel part in which near-vertical compressional stress is progressively accumulated to generate isolated shocks like the 2015 event and eventually to initiate slab penetration.

Branching patterns of trunk lateral line nerves in Pleuronectiformes: uniformity and diversity

Branching patterns of the trunk lateral line nerves were studied in 46 pleuronectiform species, representing nine families in two suborders. The dorsal fin longitudinal ramus (DFLR), derived from the main nerve (horizontal septum lateral line nerve), passed closely along the course of the middle trunk lateral line in all specimens examined, the dorsal longitudinal collector nerve (DLCN) partly coalescing with the DFLR along the arched part of the lateral line in Psettodeserumei (Psettodoidei), compared with the entire length of the latter in all other species (Pleuronectoidei). Citharidae, Paralichthyidae, and Pleuronectidae were characterized by having a simple, elongated dorsal ramule; Bothidae was unique in having more than one dorsal ramule, forming a ladder-like network and peripherally giving off numerous minute branches; Poecilopsettidae and Samaridae possessed a few, short dorsal ramules; Soleidae and Cynoglossidae were characteristic in having a dendritic dorsal ramule. Secondary modifications of the course of the middle trunk lateral line were detected by nerve information, the arched part of the lateral line having been secondarily highly elevated in some genera of Pleuronectidae, but secondarily straightened in Samaridae.

Fever of Unknown Origin as a Primary Presentation of Chronic Aortic Dissection

Fever of unknown origin is rare as a primary presentation of aortic dissection. We describe a 69-year-old female presenting with a sustained fever. A diagnosis of chronic type A aortic dissection was established by computed tomography. Replacements of the ascending aorta and part of the aortic arch were performed. Ten days after the operation, the patient had recurrent pyrexia. A large effusion in the left pleural cavity was found. After puncture aspiration and antibiotic treatment, she recovered. She was doing well at the 5(1/2)-year follow-up.

New insights into the Hercynian Orogeny, and their implications for the Paleozoic Hydrocarbon System in the Arabian Plate

ABSTRACTDuring the past decade, considerable improvements in the seismic imaging of the deeper Paleozoic section, along with data from new well penetrations, have significantly improved our understanding of the mid-Carboniferous deformational event. Because it occurred at the same time as the Hercynian Orogeny in Europe, North Africa and North America it has been commonly referred to by the same name in the Middle East. This was the main tectonic event during the late Paleozoic, which initiated or reactivated many of the N-trending block uplifts that underlie the major hydrocarbon accumulations in eastern Arabia.The nature of the Hercynian deformation away from these structural features was poorly understood due to inadequate seismic imaging and insufficient well control, along with the tectonic overprint of subsequent deformation events. Three Hercynian NE-trending arches are recognized in the Arabian Plate (1) the Levant Arch, which extended from Egypt to Turkey along the coast of the Mediterranean Sea, (2) the Al-Batin Arch, which extended from the Arabian Shield through Kuwait to Iran, and (3) the Oman-Hadhramaut Arch, which extended along the southeast coast of Oman and Yemen. These arches were initiated during the mid-Carboniferous Hercynian Orogeny, and persisted until they were covered unconformably by the Khuff Formation during the Late Permian. Two Hercynian basins separate these arches: the Nafud-Ma’aniya Basin in the north and Faydah-Jafurah Basin in the south.The pre-Hercynian Paleozoic section was extensively eroded over the arches, resulting in a major angular unconformity, but generally preserved within the basins. Our interpretation suggests that most of the Arabian Shield, except the western highlands along the Red Sea, is the exhumed part of the Al-Batin Arch. The Hercynian structural fabric of regional arches and basins continue in northern Africa, and in general appear to be oriented orthogonal to the old margin of the Gondwana continent. The Hercynian structure of arches and basins was partly obliterated by subsequent Mesozoic and Cenozoic tectonic events. In eastern Saudi Arabia, Qatar, and Kuwait, regional extension during the Triassic formed N-trending horsts and graben that cut across the NE-trending Hercynian mega-structures, which locally inverted them. Subsequent reactivation during the Cretaceous and Neogene resulted in additional growth of the N-trending structures.The Hercynian Arches had major impact on the Paleozoic hydrocarbon accumulations. The Silurian source rocks are generally preserved in the basins and eroded over the arches, which generally confined Silurian-sourced hydrocarbons either within the basins or along their flanks. Furthermore, the relict Hercynian paleo-topography generally confined the post-Hercynian continental clastics of the Unayzah Formation and equivalents to the Hercynian basins. These clastics contain the main Paleozoic oil and gas reservoirs, particularly along the basin margins where they overlie the sub-crop of the Silurian section with angular unconformity, thus juxtaposing reservoir and source rock.

The braincase of the chondrichthyanDoliodusfrom the Lower Devonian Campbellton Formation of New Brunswick, Canada

AbstractThe braincase of the late Lower Devonian (Emsian) chondrichthyanDoliodusis described for the first time. Its postorbital process is extended ventrally and probably enclosed part of the infraorbital sensory canal, as in some placoderms.Doliodushas a shark‐like dentition, but its upper anterior tooth files were supported by the internasal cartilage of the braincase, not by the palatoquadrates. Modern selachian jaws and dentitions are not representative of primitive crown‐group gnathostomes because they display a mixture of conserved and derived character states. Separation of the palatoquadrates by the internasal cartilage is probably a primitive condition for crown‐group gnathostomes. Continuity of the upper dental arcade across the ethmoid region may represent a synapomorphy of chondrichthyans and some acanthodians (the condition is not found in placoderms or osteichthyans). Exclusion of the arcade from the ethmoid region is probably apomorphic within elasmobranchs.Doliodushas curious bar‐like, paired subcranial ridges ending posteriorly at the hyomandibular articulation. These superficially resemble visceral arch infrapharyngohyals fused to the floor of the braincase, adding circumstantial palaeontological support to the old proposal that parts of visceral arches may be incorporated into the gnathostome braincase, although it seems more plausible that they formed in the lateral margins of the embryonic parachordal or hypotic lamina.

The taxonomic status of Theragra finnmarchica Koefoed, 1956 (Teleostei: Gadidae): perspectives from morphological and molecular data

The gadoid fishes Theragra finnmarchica from the coast of northern Norway and Theragra chalcogramma from the north‐east Pacific could not be taxonomically discriminated by sequencing the mitochondrial cytochrome c oxidase I (COI) gene. However, the taxa differed in 10 of 42 non‐osteological and in four of 17 osteological characters. Ontogenetic changes were found for 16 of the examined non‐osteological characters. Five taxon‐specific characters, unaffected by ontogenetic scaling, were examined by discriminant analysis. A 100% correct classification was obtained from a discriminant function based on number of pyloric caeca and number of gill rakers on the upper part of the gill arch. However, all examined characters overlapped between the two taxa, except the number of pyloric caeca. On the basis of their genetic similarity and slight morphological differences, T. finnmarchica should be considered a junior synonym of T. chalcogramma.
