La exploración petrolífera y la formación de las reservas

Si se compara la bajísima producción de petróleo por kilómetro cuadrado de la Argentina, con la de otras regiones ricas, se concluye que ella no es un país productor de petróleo. Se analiza el crecimiento futuro del consumo, deduciéndose que se deberán incrementar las inversiones para poder satisfacer las necesidades futuras.If the very low petroleum production per square kilometer of Argentine is compared with some other rich regions, the conclusion is that this country is not a petroleum producer. The consumption future growth is analyzed and it is deduced that investments should be increased to satisfy future needs.Asociación Argentina de Geofísicos y Geodesta

Astigmatism in the basic Offner spectrometer

The in-plane configuration of the basic Offner spectrometer is revised. The locations of meridional and sagittal images of the slit center are analyzed when the slit is displaced in the axial direction from the usual configuration, whereas its center is kept on the Rowland circle of the concave mirror. This translates the position of the sagittal image plane and allows for the cancellation of astigmatism and meridional coma for two wavelengths while these aberrations are kept small over the whole spectral range. This is accomplished without splitting the concave mirror into two different mirrors, simplifying the design and its practical implementation. A design example is presented with excellent optical performanceXunta de Galicia, Consellería de Educación, Universidades e FP, Spain, Grant GRC number ED431C2018/11 and ED431E2018/08S

A Polygonal Model to Design and Fabricate Ion-Exchanged Diffraction Gratings

We propose a simple polygonal model to describe the phase profile of ion-exchanged gratings. This model enables the design of these gratings, as well as the characterization of the ion-exchange process itself. Several ion-exchanged gratings were fabricated to validate the model and to characterize the process involved in their fabrication. From this characterization, we show the practical utility of the model by designing and fabricating both a grating that removes the zero order and a three splitter. The performance of these two elements was good, although the first one stood out especially because only 0.5% of the power remained in the zero order after diffraction. This polygonal model could be useful to design more complex diffractive elementsThis research was funded by Xunta de Galicia, Consellería de Educación, Universidades e FP, Grant GRC number ED431C2018/11, and Ministerio de Economía, Industria y Competitividad, Gobierno de España, Grant Number AYA2016-78773-C2-2-PS

Quantum projectors implemented with optical directional couplers in ion-exchanged glasses

Ion-exchanged glass as a platform for quantum photonics is proposed. Quantum projectors are implemented with integrated optical directional couplers fabricated by ion-exchange K+/Na+ in soda-lime glass. We consider devices composed of concatenated directional couplers which implement N-dimensional quantum projective measurements, and concomitantly the production of 1-qudit states. The fundamental units of these devices are 2 × 2 directional couplers that are experimentally studied in order to obtain, through an optical characterization, empiric relationships between fabrication and optical parameters of such couplers. Likewise, a two-dimensional quantum projector is demonstrated so that projective measurements are obtained for the states of bases X (diagonal) and Y (circular)S

Compromising between European and US allergen immunotherapy schools: Discussions from GUIMIT, the Mexican immunotherapy guidelines

Background: Allergen immunotherapy (AIT) has a longstanding history and still remains the only disease-changing treatment for allergic rhinitis and asthma. Over the years 2 different schools have developed their strategies: the United States (US) and the European. Allergen extracts available in these regions are adapted to local practice. In other parts of the world, extracts from both regions and local ones are commercialized, as in Mexico. Here, local experts developed a national AIT guideline (GUIMIT 2019) searching for compromises between both schools. Methods: Using ADAPTE methodology for transculturizing guidelines and AGREE-II for evaluating guideline quality, GUIMIT selected 3 high-quality Main Reference Guidelines (MRGs): the European Academy of Allergy, Asthma and Immunology (EAACI) guideines, the S2k guideline of various German-speaking medical societies (2014), and the US Practice Parameters on Allergen Immunotherapy 2011. We formulated clinical questions and based responses on the fused evidence available in the MRGs, combined with local possibilities, patient's preference, and costs. We came across several issues on which the MRGs disagreed. These are presented here along with arguments of GUIMIT members to resolve them. GUIMIT (for a complete English version, see Supplementary data) concluded the following: Results: Related to the diagnosis of IgE-mediated respiratory allergy, apart from skin prick testing complementary tests (challenges, in vitro testing and molecular such as species-specific allergens) might be useful in selected cases to inform AIT composition. AIT is indicated in allergic rhinitis and suggested in allergic asthma (once controlled) and IgE-mediated atopic dermatitis. Concerning the correct subcutaneous AIT dose for compounding vials according to the US school: dosing tables and formula are given; up to 4 non-related allergens can be mixed, refraining from mixing high with low protease extracts. When using European extracts: the manufacturer's indications should be followed; in multi-allergic patients 2 simultaneous injections can be given (100% consensus); mixing is discouraged. In Mexico only allergoid tablets are available; based on doses used in all sublingual immunotherapy (SLIT) publications referenced in MRGs, GUIMIT suggests a probable effective dose related to subcutaneous immunotherapy (SCIT) might be: 50–200% of the monthly SCIT dose given daily, maximum mixing 4 allergens. Also, a table with practical suggestions on non-evidence-existing issues, developed with a simplified Delphi method, is added. Finally, dissemination and implementation of guidelines is briefly discussed, explaining how we used online tools for this in Mexico. Conclusions: Countries where European and American AIT extracts are available should adjust AIT according to which school is followed

Cruise Summary Report - MEDWAVES survey. MEDiterranean out flow WAter and Vulnerable EcosystemS (MEDWAVES)

The MEDWAVES (MEDiterranean out flow WAter and Vulnerable EcosystemS) cruise targeted areas under the potential influence of the MOW within the Mediterranean and Atlantic realms. These include seamounts where Cold-water corals (CWCs) have been reported but that are still poorly known, and which may act as essential “stepping stones” connecting fauna of seamounts in the Mediterranean with those of the continental shelf of Portugal, the Azores and the Mid-Atlantic Ridge. During MEDWAVES sampling has been conducted in two of the case studies of ATLAS: Case study 7 (Gulf of Cádiz-Strait of Gibraltar-Alboran Sea) and Case study 8 (Azores). The initially targeted areas in the Atlantic were: the Gazul Mud volcano, in the Gulf of Cádiz (GoC) area, included in the case study 7, and the Atlantic seamounts Ormonde (Portuguese shelf) and Formigas (by Azores), both part of the case study 8. In the Mediterranean the targeted areas were The Guadiaro submarine canyon and the Seco de los Olivos (also known as Chella Bank) seamount. Unfortunately it was not possible to sample in Guadiaro due to time constraints originated by adverse meteorological conditions which obligate us to reduce the time at sea focusing only in 4 of the 5 initially planned areas. MEDWAVES was structured in two legs; the first leg took place from the 21st September (departure from Cádiz harbour in Spain) to the 13th October 2016 (arrival in Ponta Delgada, São Miguel, Azores, Portugal took place the 8th of October due to the meteorological conditions that obligated to conclude the first leg earlier as planned). during the Leg 1 sampling was carried out in Gazul, Ormonde and Formigas. The second leg started the 14th October (departure from Ponta Delgada) and finished the 26th October (arrival in Málaga harbour, Spain). MEDWAVES had a total of 30 effective sampling days, being 6 days not operative due to the adverse meteorological conditions experienced during the first leg which forced us to stay in Ponta Delgada from the 08th to the 13th October. During MEDWAVES the daily routine followed a similar scheme, depending of course on the weather and sea conditions. The main activity during the day, starting early in the morning (around 08:00 AM, once the night activities were finished), was the ROV deployment. Generally a single ROV dive of around 8 hours was performed, however in several occasions two dives were carried out in the same day (see General station list, Appendix II). After the ROV (and sometimes between two dives) the Box Corer and/or Van Veen Grab and/or Multicore was deployed. After these activities, during the night CTD-Rosette deployments and MB was conducted. Accordingly to this schema the scientific personnel worked in the day or in the night watch. A total of 215 sampling stations have been covered in MEDWAVES, using the following sampling gears: Multibeam echosounder, CTD-Rosette, LADCP, Box Corer, Van Veen Grab, Multicorer and a Remotely Operated Vehicle (ROV). Table 1 sumamrised the number of sampling stations conducted with each gear in each sampling zone. Additionally MB surveys have been conducted during the transits between area

XXV Curso Monográfico de Psiquiatría Infantil y la Adolescencia: Tópicos de Psicofarmacología Infantil - 2023

El XXV Curso Monográfico de Psiquiatría Infantil y de la Adolescencia, titulado "Tópicos de Psicofarmacología Infantil," fue un evento destacado en el campo de la salud mental infantil y adolescente. Durante tres días en septiembre de 2023, expertos líderes en la materia se reunieron para explorar a fondo la psicofarmacología en este grupo de edad. El evento, dedicado a la memoria del Dr. Francisco Javier Valencia Granados, comenzó con una ceremonia de inauguración en la que participaron autoridades institucionales. Luego, se sucedieron conferencias magistrales que abordaron una amplia variedad de temas cruciales. Estos incluyeron aspectos fundamentales como la neurobioquímica farmacológica y una introducción a la psicofarmacología. El programa se adentró en cuestiones específicas, como el uso de antipsicóticos en paidopsiquiatría, el abordaje de trastornos del aprendizaje, el tratamiento del suicidio desde una perspectiva psicofarmacológica, y la gestión farmacológica del insomnio en niños. Se exploraron temas especializados, como el tratamiento de la esquizofrenia en pacientes infantiles. El segundo día se centró en trastornos emocionales en niños y adolescentes, destacando el tratamiento del trastorno depresivo, los trastornos ansiosos y el espectro autista. Se presentaron enfoques vanguardistas, como el uso de psicodélicos en adolescentes y las novedades en psicofarmacología, como el dextrometorfano y el bupropión. También se discutió el manejo de la epilepsia y la adicción a los videojuegos. El tercer día se enfocó en el tratamiento farmacológico de trastornos pediátricos específicos, como el trastorno bipolar, el déficit de atención e hiperactividad, la enuresis y encopresis, parasomnias, y el abordaje neuropsiquiátrico en pacientes pediátricos con VIH. Se exploraron también trastornos de la conducta alimentaria y la disforia de género. El evento culminó con una reflexión sobre la salud mental en niños y un emotivo tributo al Dr. Francisco Javier
