Fluid geochemistry of the San Vicente geothermal field (El Salvador)
1997
The volcano Chichontepeque (San Vicente) is one of the nine recent volcanoes making up the El Salvador sector of the WNW-ESE-trending active Central American volcanic belt. Thermal activity is at present reduced to a few thermal springs and fumaroles. The most important manifestations (Agua Agria and Los Infernillos Ciegos) are boiling springs and fumaroles located on the northern slope of the volcano (850 m a.s.l.) along two radial faults. The chloride acid waters of the Los Infernillos area are partly fed by a deep hydrothermal aquifer (crossed at 1100–1300 m by a geothermal exploration well), which finds a preferential path to the surface through the radial fault system. C02 is the most …
Subsurface geometries in central sicily FTB as a premise for hydrocarbon exploration
2008
The study concerns a sector of the Maghrebian Sicilian Fold and Thrust Belt (FTB), located in central Sicily between the southern edge of the Madonie Mts. and the Caltanissetta trough. Interpretation of recently acquired seismic profiles, constrained by joint detailed stratigraphy and field investigation, revealed the structure of the study area as formed by a thick pile of deep water carbonate (Imerese and Sicanian) thrusts lying on carbonate platform imbricates. In the forward migration of the FTB, two main tectonic events were envisaged; shallow and deep seated thrusts occurred during the Miocene-early Pleistocene time interval that deformed the former sedimentary cover of the continenta…
Building sustainable contextual ambidexterity through routines: a case study from information technology firms
2020
The purpose of this paper is to explain the role that routines play in achieving sustainable organisational ambidexterity in information technology (IT) firms. Our exploratory analysis of four case studies reveals the key importance of routines in setting the context for sustainable ambidexterity. Companies build up contextual ambidexterity through routines derived from normalization of processes, normalization of skills, and normalization of results. The findings of the study show that routines support IT professionals to decide whether to exploit or explore in each particular case. Firstly, the enabling character of explicit routines as a result of the normalisation of work processes and …
How customer knowledge affects exploration : generating, guiding, and gatekeeping
2021
The importance of understanding customers in order to sustain the long-term success of the company has been claimed by academics and practitioners for decades, to the point that the claim has turned into a truism. And still, the role of customer knowledge in organizational renewal, especially via explorative new product development (NPD), remains ambiguous. While existing literature generally emphasizes the value of customer knowledge, critics argue that a strong customer focus can also de-motivate and misguide exploration. This study adds clarity to our understanding of this tension by drawing from an intensive analysis of the corporate archives of a rapidly growing high-tech company. The …
Individual differences in behavioral consistency are related to sequential access to resources and body condition in a producer-scrounger game
2014
Investigating the evolution of consistent between-individual behavioral differences necessitates to explain the emergence of within-individual consistency. Relying on a recent mathematical model, we here test the prediction that the emergence of differences in within-individual consistency is related to the sequential access to resources in a frequency-dependent foraging game. To this end we used flocks of zebra finches (Taeniopygia guttata) engaged in a producer-scrounger foraging game. Tactic investment (i.e., the proportion of hops with the head down) significantly predicted successful tactic use (i.e., the proportion of seeds produced). In support of predictions, we found that individua…
Common Bile Duct Stones in Cholecystectomized Patients
2008
The incidence of retained or primary stones is approximately 2–5% after conventional and laparoscopic cholecystectomy (LC) and 5–15% after common bile duct exploration (CBDE) [1]: in principle these patients are in need of further intervention [2, 3].
Ergebnisse der bilateralen Operationstechnik bei primärem Hyperparathyreoidismus
2001
AIM OF THE STUDY The surgical success rate and clinical outcome after surgery for primary hyperparathyroidism were evaluated in a prospective long-term follow-up study. PATIENTS AND METHODS 407 patients, 396 with the first manifestation, 6 with recurrent and 5 with persistent disease underwent operation from August 1, 1987 to August 15, 1999. All patients were prospectively investigated in a long-term follow-up study and underwent reexaminations at regular surveillance intervals. The postoperative course is known in 93.9% of all patients. RESULTS The prevalence of asymptomatic primary hyperparathyroidism was 5.6% in our patients. Surgical cure was obtained in 97.7% of patients after initial…
Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia
2021
Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…
Peripersonal Visuospatial Abilities in Williams Syndrome Analyzed by a Table Radial Arm Maze Task
2020
Williams syndrome (WS) is a genetic deletion syndrome characterized by severe visuospatial deficits affecting spatial exploration and navigation abilities in extra-personal space.To date, little is known about spatial elaboration and reaching abilities in the peripersonal space in individuals with WS. The present study is aimed at evaluating the visuospatial abilities in individuals with WS and comparing their performances with those of mental age-matched typically developing (TD) children by using a highly sensitive ecological version of the Radial Arm Maze (table RAM). We evaluated 15 individuals with WS and 15 TD children in two different table RAM paradigms: the free-choice paradigm, ma…
