A Rare, Complicated Busoga Hernia

Inguinal herniae are the most common herniae encountered in the Surgical OPD or even the emergency setting. The indirect variety has a higher rate of bowel obstruction due to the constriction of the sac at the superficial ring. Direct herniae, owing to the larger defect, are relatively safe from complications. Busoga hernia (1) is a rare subtype, which is prone to strangulation of contents, owing to the extremely narrow neck under continual tension within a tough fascial sling.

On-machine measurement and error analysis for narrow neck thickness based on ultra-precision machine tool

As flexible joint is a typical low-rigidity micro part, which have four narrow neck structures evenly distributed around its central axis, it is necessary to strictly control the dimensional accuracy of the narrow necks to improve the consistency of stiffness. However, the radius of the arc of the narrow necks is less than 2mm , and the thickness of thinnest part of the necks formed by two adjacent arcs is only tens of microns, which also has sub-micron accuracy requirement. These cross-scale dimensional characteristics and accuracy requirements give rise to extremely difficulty on the measuring process. In this paper, an on-machine measurement method for the semicircular narrow necks was presented and a measuring device was developed based on the comparative principle by making full use of the high linearity characteristic in the small measuring range of the sensor probes. Meanwhile, the on-machine measurement process based on ultra-precision machine tools was also introduced in details. The experiments results show that the measurement error of the method proposed is less than 0.2 µm , and the repeatability is less than 0.1 μm , which meet the measuring requirement of flexible joint. Furthermore, the theoretical error and the uncertainty caused by probe position, measurement force, environmental factor and the accuracy of the sensor was analyzed, which could provide further evidences to improve the measuring accuracy of micro-scale hybrid surface texture.

Ceramic lids from pre-Mongolian Panjakent and its surroundings

This paper presents a classification of ceramic lids of the late 8th — early 13th century found in Panjakent and its surroundings. The examples considered include 71 items, many of which can be reconstructed. In terms of their shape, the author divides them into 10 groups. The lids were used mainly for cauldrons, as well as for jugs with a narrow neck, pots, “khumcha” storage pots and braziers.

How the Goths and Alans of the Mountainous Crimea Assimilated Greek Language

The Goths and Alans settled in the Mountainous Crimea about the mid-third century. The Eastern Roman Empire pursued the policy of integrating barbarians on the frontier in order to strengthen its northern borders. In the mountainous Crimea, the Goths and Alans assimilated Greek language in result of political and ideological interaction and trading with Cherson and other cities and towns of the Eastern Roman Empire. The earliest in this area Greek inscriptions were dipinti drawn on the light-clay narrow-neck amphorae of D. B. Shelov’s type F, which were produced in Herakleia Pontike. According to the life of St. John of Gothia who led a revolt against Khazar domination in Gothia, the correspondence of Theodore of Stoudios with the archimandrite of Gothia, and official church documents, Greek was the only language of worship in the churches and monasteries of Gothia from the establishment of the Gothic bishopric on. The priests and monks contributed to the spread of Greek language among the Goths and Alans. From the eighth to thirteenth centuries, there appeared numerous epitaphs in church burials and in cemeteries located around these churches starting with a typical Byzantine phrase: Φῶς ζωή (“Light – life”), Κύριε, βοήθει... (“Lord, help...”), Ἰησοῦς Χριστὸς νηκᾷ (“Jesus Christ conquers”), Ἐκοιμήθη (“Deceased” or “passed away”), and so on. From the materials examined there are reasons to state that, by the ninth century, the Goths and Alans assimilated Greek language, which from the ninth to thirteenth centuries predominated in Gothia. There are several written sources documenting the preservation of Gothic and Alan languages in the first half of the thirteenth century. In the mid-sixteenth century, the Goths of the mountainous Crimea spoke mostly Greek. According to written sources, the functioning of Crimean Gothic dialect was restricted and started disappearing from the sixteenth century on.

Immediate post-operative aneurysm occlusion after endovascular treatment of intracranial aneurysms with coiling or balloon-assisted coiling in a prospective multicenter cohort of 1189 patients: Analysis of Recanalization after Endovascular Treatment of intracranial Aneurysm (ARETA) Study

BackgroundCoiling, including balloon-assisted coiling (BAC), is the first-line therapy for ruptured and unruptured aneurysms. Its efficacy can be clinically evaluated by bleeding/rebleeding rate after coiling, and anatomically evaluated by aneurysm occlusion post-procedure and during follow-up. We aimed to analyze immediate post-coiling aneurysm occlusion and associated factors within the Analysis of Recanalization after Endovascular Treatment of intracranial Aneurysm (ARETA) population.MethodsBetween December 2013 and May 2015, 16 neurointerventional departments prospectively enrolled participants treated for ruptured and unruptured aneurysms (ClinicalTrials.gov: NCT01942512). Participant demographics, aneurysm characteristics, and endovascular techniques were recorded. In patients with aneurysms treated by coiling or BAC, immediate post-operative aneurysm occlusion was independently evaluated by a core lab using a 3-grade scale: complete occlusion, neck remnant, and aneurysm remnant.ResultsOf 1135 participants (age 53.8±12.8 years, 754 women (66.4%)), 1189 aneurysms were analyzed. Treatment modality was standard coiling in 645/1189 aneurysms (54.2%) and BAC in 544/1189 (45.8%). Immediate post-operative aneurysm occlusion was complete occlusion in 57.8%, neck remnant in 34.4%, and aneurysm remnant in 7.8%. Adequate occlusion (complete occlusion or neck remnant) was significantly more frequent in aneurysms with size <10 mm (93.1% vs 86.3%; OR 1.8, 95% CI 1.1 to 3.2; p=0.02) and in aneurysms with a narrow neck (95.8% vs 89.6%; OR 2.5, 95% CI 1.5 to 4.1; p=0.0004). Patients aged <70 years had significantly more adequate occlusion (92.7% vs 87.2%; OR 1.9, 95% CI 1.1 to 3.4; p=0.04).ConclusionsImmediately after aneurysm coiling, including BAC, adequate aneurysm occlusion was obtained in 92.2%. Age <70 years, aneurysm size <10 mm, and narrow neck were factors associated with adequate occlusion.Trial registration numberNCT01942512, http://www.clinicaltrials.gov.

Congenital right ventricular aneurysm with characteristics of a pseudoaneurysm

We report a case of an isolated congenital right ventricular outpouching detected incidentally on foetal echocardiogram that was performed due to suspicion of CHD. Subsequent echocardiogram after birth revealed an aneurysm with features of a pseudoaneurysm having a thin and hypokinetic wall connected to the ventricleʼs cavity via a narrow neck. This pseudoaneurysm appears to be stable in size and of no clinical significance during the short-term follow-up.

Comparison of automation and digitalization concepts in industry

The purpose of the article is the study of the «automation» and «digitalization» concepts in production, their systematization and a clear distinction. The definitions, the essence of digitalization and automation in the framework of the fifth and sixth technological structures are considered. The technologies and effects generated and associated with automation and digitalization are presented. The production and management aspects of comparing these concepts are given. Practical proof of the difference between the concepts is shown by the example of the added cost and value chain. Keywords automation; digitalization; production; «narrow neck» effect
