ERT and VES studies for thermo-mineral water in Toplita area, Romania

Abstract. The development of Toplița geothermal spa for tourism requires new geothermal resources, geophysical and hydrogeological works being carried out during the last decades. A geophysical study based on the new ERT (Electric Resistivity Tomography) technique was recently performed, the resistivity tomography data being integrated with gravity, magnetics and previous VES (Vertical Electric Sounding) measurements (Ursu, 1994). Experiments related to applying the ERT technique in the Bradul spa area (Toplița) showed that the Schlumberger array provides better results for deeper levels as compared to the Wenner one. To better illustrate the spatial distribution of apparent resistivity within the subsurface structures the VES sections were calculated for AB/2 and AB/3. The integrated interpretation of ERT and VES resistivity data lead to the drilling of a new hydrogeological borehole in the Bradul spa area. A highly tectonized zone containing thermo-mineral water was twice crossed at 190m and 200m depth, its temperature being similar to that exploited in the Bradul spa (27 0C). When estimating the depth of apparent resistivity anomalies in the Bradul spa area a better fit was offered by the VES section calculated for AB/2.5

BRIEF PRESENTATION OF THE ORDER NO. 344/708/2004 OF THE MINISTRY OF ENVIRONMENT AND WATER MANAGEMENT AND THE MINISTRY OF AGRICULTURE AND RURAL DEVELOPMENT TO APPLY SEWAGE SLUDGE ON A STAGNIC PRELUVOSOL

Within this paper there briefly presented the technical norms comprised in theOrder for using sewage sludge and the evaluation criteria of soils in order to apply as fertilizer. There were studied the physical and chemical features of a stagnic preluvosol (stagnic luvisol) in order to asses the possibility to fertilize it by sewage sludge. The paper has an informative role for local farmers who can benefit by sewage sludge from Wastewater Treatment Plants of Craiova and Calafat

STRESS CONCENTRATION DUE TO A SPHERICAL VOID UNDER HERTZIAN CONTACT

The present paper presents the method of estimating the stress concentrator effect of a spherical void from an elastic half-space. An essential part consists in estimation of FEM error by finding the contact pressure from half-plane using an analytical method. Next, the stress concentrator effect of the same void, except for placed into elastic space, is found

Acute chylous peritonitis due to idiopathic pancreatitis mimicking acute appendicitis

The acute development and the accumulation of chyle into the peritoneal space is a rare condition and one needs to be able to distinguish it from chylous ascites, which is most commonly chronic and associated with related diseases. It is frequently idiopathic and additionally, clinical and imaging findings are nonspecific. In almost all cases, the diagnosis is made intraoperatively during laparoscopy or laparotomy, most diagnostic procedures being indicated by acute complaints pertaining to the abdomen. A 23-year-old man was admitted to the Emergency Department with abdominal pain, with right iliac fossa tenderness and peritonism. Laparoscopy was performed due to acute abdomen findings. Further exploration revealed chylous effusion with milky-like fluid. The peritoneal lavage and the insertion of drains were subsequent to the careful inspection of the cavity. The biochemical analysis of the peritoneal fluid was an important aid which provided the diagnosis of chylous peritonitis due to acute pancreatitis

Abdominal-pelvic pain in female patients with endometriosis - a review of the literature

Abdominal-pelvic pain is the dominant symptom in endometriosis, one of the most common pathologies that affect women, being also a multifactorial disorder. Exploratory laparoscopy allows the correct assessment of the location as well as severity and extent of the lesions, thus representing the current gold standard in diagnosis. The correlation of pain intensity with the evolutionary stage of endometriosis is inconstant. Surgical treatment, preferably performed laparoscopically, includes the excision of the ectopic endometrium, having as a primary objective the control of persistent pain and the removal of all endometriotic foci. This procedure helps to improve the life quality of the patient, to reduce relapses, to control postoperative pain, and to eliminate the disease. Pre- and post-operative adjuvant medical treatment is used due to its effects on the symptomatology, prolonging the asymptomatic period of the disease. Despite the use of the above procedures, there are cases in which the abdominal-pelvic pain persists even after surgery, which makes endometriosis a significant challenge for both the specialist and the patient, as well as for the medical system itself, as the study of the pathogenic mechanisms is yet the subject of numerous studies. Nutritional education in these patients is essential, given the recommendation to restrict the range of foods and to increase other foods that have an important role in reducing the risk or even leading to regression of the endometrial pathology

The title compound, C33H25N5, belongs to the family of pyridine-2,6-dicarboxaldehyde Schiff bases which possess a terdentate coordinating site (–N=C–C=N–C–C=N–) similar to terpyridine derivatives. The dihedral angles between pairs of terminal rings are 69.67 (9) and 66.23 (9)°. The shortest distance between the centroids of aromatic rings in neighbouring mol­ecules is 3.8080 (14) Å

The Deregulation Trap in Today's Energy Markets

The deregulation of the energy industry has long been a contentious issue. Opponents claim that it can lead to higher pricing, poorer dependability, and market manipulation, while supporters claim that it results in increased competition, cheaper prices, and improved efficiency. Overall, energy market deregulation can have both positive and negative effects, depending on the specific circumstances of each market. While deregulation can lead to greater competition, efficiency, and choice, it can also create greater volatility and risk if not properly managed. Therefore, policymakers and regulators need to carefully consider the potential benefits and drawbacks of deregulation before implementing any changes to the market structure. This research essay looks at the historical background and justification for the deregulation of the energy market, the effects it has on consumers, and the opportunity for regulatory control to lessen any unfavorable effects

Outsourcing in Today's Economic Environment

An economic phenomenon that is defined by the movement of industrial activity from developed to emerging nations has occurred during the past two decades. This technique may be seen as the huge firms' solution to the issue of production costs that were steadily growing along with rising living standards and compensation. This paper seeks to study outsourcing from the standpoint of its evolution as well as the benefits and drawbacks that come with it. On the other hand, this research essay aims to define the concept's foundations and explore its applicability to the public sector. Overall, research on outsourcing has shown that outsourcing can provide significant benefits in terms of cost savings, flexibility, and quality, but it also presents challenges in terms of managing relationships, maintaining control, and managing the human resources aspects of outsourcing. Companies need to carefully consider the potential benefits and risks of outsourcing before deciding whether to outsource specific functions or processes

Tris[4-(2-pyridylmethyl­eneamino)phenol]iron(II) bis­(perchlorate)

In the title compound, [Fe(C12H10N2O)3](ClO4)2, the metal center is coordinated by six N atoms from the three bidentate chelating ligands in a distorted octa­hedral coordination geometry, with overall formation of the meridional (OC-6-21) isomer. Inter­molecular O—H⋯O hydrogen bonds between the hydroxyl groups of the cation and the counter-anions form an infinite one-dimensional chain in the c-axis direction
