The Common

In this chapter we describe the common modes of failure of the OUKA and suggest ways of dealing with them. We also discuss why they occur and how they can be prevented. Complications occur more commonly in the hands of learners than in those of the experienced surgeons whose reports are published in the literature. As a result, the incidence of complications is lower in published cohort series compared to national registers.

Prompt Diagnosis

This pictorial review will describe the normal anatomy of whole organ pancreatic transplants and the common surgical variants with which the radiologist should be familiar. Complications may be divided into (1) vascular: arterial occlusion and stenosis, venous thrombosis, pseudoaneurysms and arteriovenous fistulae, (2) parenchymal complications such as pancreatitis and the variety of peripancreatic collections, and (3) enteric complications including leak and fistula formation. The radiologist plays a crucial role in the initial assessment of graft anatomy and perfusion, prompt diagnosis, and increasingly, in the management of complications.

Theoretical Results

The paper reviews the main requirements fulfilled by a cylinder head or cylinder block and outlines the common modes of failure met with in practice. The relative importance of the various loads applied to the head in operation are assessed and a method of predicting their influence on the structural integrity of the component described. The theoretical results obtained from a range of cylinder heads covering engines in the bore range 4 3/8 in (110 mm) to 17 in (430 mm) are shown and the experimental data obtained from verification tests presented. A quick design-assessment criterion is derived and the design-optimization procedure evolved is discussed. It is concluded that on highly rated engines the critical section is usually located at the narrow flame-plate section between adjacent exhaust-valve ports. Failures are mainly due to thermal overload. The cylinder head's rating can be extended by reducing the bottom-deck temperatures and the axial stiffness of the head and by adopting more advantageous materials for the bottom deck. Typical examples are illustrated.

Ovarian Syndrome

ABSTRACT In women of reproductive age polycystic ovary syndrome (PCOS) is the common endocrine disorder. It is one of the common causes of infertility due to anovulation. There is no single criterion for the diagnosis of this syndrome. It is crucial to diagnose PCOS early in its course since it has lifelong implications with increased risk for metabolic syndrome, type II Diabetes mellitus (DM), cardiovascular disease, endometrial hyperplasia, infertility and depression. Screening for the impaired glucose (IGT), allows for proper and timely prevention and management of complications. In this cross sectional study, we planned to detect the prevalence of impaired glucose tolerance and diabetes in women with PCOS which will facilitate prevention of long term sequelae. We also studied the extent of the risk for diabetes in patients with PCOS in relation to age, socioeconomic status, rural and urban areas, BMI, waist/hip circumference ratio, family history of PCOS and diabetes mellitus How to cite this article Smitha CHC, Sailakshmi MOPA, Nagaratnamma R.

Abstract Background: Critical limb ischemia is considered the most severe form of peripheral artery disease. High morbidity and mortality rates are associated with this pathology due to poor economic management of complications. Case summary: A 68-year-old female patient underwent a routine Doppler ultrasound which revealed the obstruction of both the common and superficial right femoral arteries, as well as the right deep femoral artery. In this case, an iliofemoral bypass was performed using the right deep femoral artery as the outflow artery. Conclusion: Revascularization of the deep femoral artery has a reasonable chance of preserving the ischemic lower limb whenever the common and superficial femoral arteries suffer major atherosclerotic blockages.

Astrometric Data

AbstractReduction techniques as applied to astrometric data material tend to split up traditionally into at least two different classes according to the observational technique used, namely transit circle observations and photographic observations. Although it is not realized fully in practice at present, the application of a blockadjustment technique for all kind of catalogue reductions is suggested. The term blockadjustment shall denote in this context the common adjustment of the principal unknowns which are the positions, proper motions and certain reduction parameters modelling the systematic properties of the observational process. Especially for old epoch catalogue data we frequently meet the situation that no independent detailed information on the telescope properties and other instrumental parameters, describing for example the measuring process, is available from special calibration observations or measurements; therefore the adjustment process should be highly self-calibrating, that means: all necessary information has to be extracted from the catalogue data themselves. Successful applications of this concept have been made already in the field of aerial photogrammetry.

The phenomenon of bioluminescence has fascinated layman and scientist alike for many centuries. During the eighteenth and nineteenth centuries a number of observations were reported on the physiology of bioluminescence in Renilla, the common sea pansy. More recently biochemists have directed their attention to the molecular basis of luminosity in this colonial form. These studies have centered primarily on defining the chemical basis for bioluminescence and its control. It is now established that bioluminescence in Renilla arises due to the luciferase-catalyzed oxidation of luciferin. This results in the creation of a product (oxyluciferin) in an electronic excited state. The transition of oxyluciferin from its excited state to the ground state leads to light emission.

Acetylcholinesterase (EC 3.1.1.7) (ACHE) has been localized at cholinergic junctions both in the central nervous system and at the periphery and it functions in neurotransmission. ACHE was also found in other tissues without involvement in neurotransmission, but exhibiting the common property of transporting water and ions. This communication describes intracellular ACHE in mammalian bone marrow and its secretion into the extracellular medium.

Till now correlation functions have been used in electron microscopy for two purposes: a) to find the common origin of two micrographs representing the same object, b) to check the optical parameters e. g. the focus. There is a third possibility of application, if all optical parameters are constant during a series of exposures. In this case all differences between the micrographs can only be caused by different noise distributions and by modifications of the object induced by radiation.Because of the electron noise, a discrete bright field image can be considered as a stochastic series Pm,where i denotes the number of the image and m (m = 1,.., M) the image element. Assuming a stable object, the expectation value of Pm would be Ηm for all images. The electron noise can be introduced by addition of stationary, mutual independent random variables nm with zero expectation and the variance. It is possible to treat the modifications of the object as a noise, too.
