OBJECTIVE: To determine ovarian blood flow characteristics using three-dimensional power Doppler ultrasound.METHODS: We examined 30 patients (30 cycles) prior to the start of their in vitro fertilization treatment in the late follicular phase using three-dimensional power Doppler ultrasound. The volume, vascularization index, flow index, vascularization flow index, mean grayness and the presence o

OBJECTIVE: Effect of the side of ovulation on uterine, ovarian, and follicular blood flow parameters and various hormone levels.DESIGN: Prospective, observational study.SETTING: Fertility Clinic, St. George's Hospital.PATIENT(S): Nineteen women with regular menstrual cycles. Pulsed Doppler measurements and serum hormonal concentrations during midfollicular, periovulatory, and midluteal phase for t

OBJECTIVE: To assess intraindividual variation of follicle stimulating hormone, luteinising hormone, estradiol, progesterone, inhibin A, and inhibin B in three successive ovulatory cycles correlated with transvaginal ultrasound monitored morphological changes in the ovary.METHODS: Serial transvaginal color and pulsed Doppler ultrasound and serum hormone analysis were performed during midfollicular

One in six couples seeks help for infertility during their reproductive years. Subfertility investigations should be performed without delays (because female fertility decreases with age) and should be as noninvasive as possible. Many fertility clinics use diagnostic hysteroscopy to assess the uterine cavity and evaluate the tubal ostia. Laparoscopy is also often used to examine internal pelvic or

This article presents the addition of camber to a previously published semi-empirical tyre model by the same authors. The model combines empirical models for pure braking, cornering and cambering with a model for simultaneous braking, cornering and cambering. It is based on brush-model tyre mechanics and aims to offer an easy-to-use accurate model for vehicle-handling simulations. The proposed mod

In this article, we respond to Cabantous, Gond, Harding and Learmonth’s (2016) critique of recent conceptual contributions that employ the concept of performativity for prompting progressive changes in organizations. All in all, we seem to share the general unease concerning the marginal impact of Critical Management Studies on re-defining organizational realities. At the same time, we largely dis

Urban planning processes are complex and multidimensional and they require re-thinking of traditional approaches. One of the theories increasingly researched by urban planners is realisation of participatory planning to facilitate public participation. This approach, as an effective bottom-up method, should increase the capabilities of planners to solve urban problems by including the general publ

In nanoindentation, roughness of the sample surface can be a severe source of error in the determination of properties from indentation tests. Recently, roughness was also considered as a crucial issue in understanding the indentation size effect where a significant increase in hardness was seen with the decrease of depth. A three-dimensional roughness model with the Johnson–Cook material model is

Experiments were performed on the central pilot body (RPLrich- pilot-lean) of Siemens prototype 4th generation DLE burner to investigate the flame behavior at atmospheric pressure condition when varying equivalence ratio, residence time and co-flow temperature. The flame at the RPL burner exit was investigated applying OH planar laser-induced fluorescence (PLIF) and high-speed chemiluminescence im

Stroke induced by middle cerebral artery occlusion in adult rodents induces the formation of new neurons in the damaged striatum, a region that normally does not show neurogenesis. Here we describe recent findings on the regulation of neurogenesis after stroke, in particular regarding the duration of the neurogenic response and the influence of age, as well as the molecular mechanisms influencing

Smaller size and lower weight are always the targets of the power electronic product development. This work introduces two new topologies of auxiliary converters which have the feature of fewer components and fewer number of energy conversion stages comparing with the conventional auxiliary converter used in railway applications. The initial proposal of the proposed new topology is based on the id

In the home garden, people inevitably interact with a multitude of non-human actors, including plants. Home gardeners get involved with, and affect, the growth, life and death of other individuals through activities such as weeding and pruning. In this article, the authors discuss people’’s everyday interactions with ‘‘nature’’ in their own gardens, with a specific focus on plants. Despite their r

I denna artikel analyseras upptakten till det moderna miljömedvetandets genombrott i Skandinavien åren kring 1970 från ett kunskapshistoriskt perspektiv. Studien tar sin utgångspunkt i det samtida mottagandet av den svenske Norgeambassadören Rolf Edbergs debattbok om mänsklighetens ödesfrågor hösten 1966. Boken gavs ut samtidigt på de tre skandinaviska språken vilket har öppnat upp för en gränsöve

I detta kapitel illustreras relationen mellan populärkultur och marknad ur ett historiskt perspektiv via ett äldre material om biogående och biosituationen på 1940- och 50-talen. Jämförelse görs mellan nu och då i syfte att se både kontinuitet och förändring. Historiskt perspektiv används som metodologiskt grepp för att se vår egen tid genom att visa på det populärkulturella kretsloppets betydelse

Despite their rootedness, plants do move and are moved between different places in the garden, and from one garden to another. In many private gardens there are plants with a history, and owners who tell stories about how they were brought in from a different location, for example from an old relative or from a journey. These plants are often regarded as relics or souvenirs, and receive special at

The Sectra MicroDose Mammography system is based on direct photon counting (with a solid-state detector), and a substantially lower dose to the breast than when using conventional systems can be expected. In this work absorbed dose measurements have been performed for the first unit used in routine mammography screening (at the Hospital of Helsingborg, Sweden). Two European protocols on dosimetry

BACKGROUND: Damage control is valuable in hemodynamically unstable trauma patients. To improve the hemostasis of packing, topical hemostatic agents have been suggested. The effects of such agents are unclear in trauma situations. The purpose of this study was to investigate the hemostatic capacity, and the stability of the hemostatic clot, of four substances with different mode of action in an exp

Carbamylated erythropoietin (CEPO) is a novel neuroprotective agent that does not bind to the classical erythropoietin receptor or affect hematocrit. Since CEPO has not been systematically studied in a fully blinded and randomized manner in an embolic stroke model, we determined if CEPO would be useful to attenuate clinical deficits associated with multiple infarct ischemia using the rabbit small

Biogas produced by anaerobic digestion is often used in gas turbines to produceelectricity. In order to increase the value of the gas and to enable utilization of the gas in other applications, it may be advantageous to upgrade the biogas. In this way, the carbon dioxide as well as various impurities are removed and biomethane is produced. Biomethane is similar to natural gas and can be used in si
