CO 2. .. Cradle of Life. .. on Planet Earth . . . Photosynthesis . . .
2023, Review Article
This abstract provides a concise overview of carbon, carbon dioxide, and the carbon cycle. Carbon is an essential element for life on Earth, serving as the building block of organic molecules found in living organisms. Carbon dioxide (CO2), a greenhouse gas, plays a dual role in supporting life through photosynthesis while also contributing to climate change when its concentration in the atmosphere increases due to human activities. The carbon cycle is a natural process that continuously cycles carbon between the atmosphere, oceans, land, and living organisms. It plays a vital role in regulating the Earth's climate, supporting plant growth through photosynthesis, sequestering carbon in natural sinks, and sustaining various ecosystems. However, human activities have disrupted the carbon cycle, leading to adverse effects such as climate change, ocean acidification, and ecosystem disturbances. Mitigating these harmful impacts requires global efforts to reduce carbon emissions, conserve forests, and adopt sustainable practices to restore the balance of the carbon cycle and ensure a more sustainable future.

It is difficult to distinguish influx and efflux of inorganic C in photosynthesizing tissues; this article examines what is known and where there are gaps in knowledge. Irreversible decarboxylases produce CO2, and CO2 is the substrate/product of enzymes that act as carboxylases and decarboxylases. Some irreversible carboxylases use CO2; others use HCO3 (-). The relative role of permeation through the lipid bilayer versus movement through CO2-selective membrane proteins in the downhill, non-energized, movement of CO2 is not clear. Passive permeation explains most CO2 entry, including terrestrial and aquatic organisms with C3 physiology and biochemistry, terrestrial C4 plants and all crassulacean acid metabolism (CAM) plants, as well as being part of some mechanisms of HCO3 (-) use in CO2 concentrating mechanism (CCM) function, although further work is needed to test the mechanism in some cases. However, there is some evidence of active CO2 influx at the plasmalemma of algae. HCO3 (-)...

La investigación en ciencias sociales podría describirse, de una forma premeditadamente simplificada, como un esfuerzo colectivo en el que se toma como punto de partida un repertorio de proposiciones teóricas para, a continuación, pulsar la realidad social con el propósito de comprobar su validez y, completando un itinerario circular, regresar al origen para enriquecer y pulir los argumentos teóricos. Se trata, por lo tanto, de un viaje de ida y vuelta en el que teoría y práctica se interpelan sin cesar, alcanzando un mayor refinamiento en función del grado de acoplamiento que alcancen. Esta relación simbiótica encuentra en el campo de la investigación cualitativa uno de los ejemplos más paradigmáticos. La propuesta teórica de la Grounded Theory, lanzada hace ya cuarenta años por Barney Glasser y Anselm Strauss, puso sobre el tablero de juego de la práctica investigadora la íntima relación que se debe conservar entre la construcción teórica y la obtención de datos empíricos. El paso de las décadas ha acabado por confirmar las potencialidades analíticas de esta forma de aproximación a la realidad social. Durante este proceso de conquista de un espacio propio en el ecosistema académico, el avance tecnológico se ha mostrado como un aliado estratégico. De hecho, sólo cuando las herramientas informáticas comenzaron a ofrecer un mínimo nivel de desarrollo y de fiabilidad, el análisis cualitativo se comenzó a perfilar como una opción viable para muchos investigadores. En este sentido, el campo abierto en la última década bajo el nombre de Computer Assisted Qualitative Data Analysis (CAQDAS) contribuyó a abrir un nuevo horizonte de posibilidad a muchos académicos y centros de investigación social. Este capítulo parte de una reflexión sobre la relación que mantienen teoría y práctica en el conjunto del proceso de investigación para, rápidamente, desembocar en la presentación de un programa de análisis cualitativo que contribuye a completar esta visión integradora de ambas etapas. ATLAS.ti es una herramienta informática que se ha construido con el objetivo de completar el itinerario dibujado desde la Grounded Theory, por lo que estas páginas intentan presentar los principales elementos que proporciona este software, así como sus relaciones con otro tipo de programas y sus limitaciones. Por desgracia, la gran cantidad de recursos que ofrece ATLAS.ti obliga a que este documento sólo pueda ser considerado como una introducción, un aperitivo cuya misión es la de abrir boca a quien esté interesado en estas herramientas. En consecuencia, es necesario advertir que para alcanzar un aprovechamiento óptimo de este programa resulta imprescindible seguir alguno de los manuales que se incluyen en la bibliografía y que han sido la base para redactar este documento. Además, y en consecuencia con la convergencia entre teoría y práctica que da forma al capítulo, la lectura de cualquier manual debe ser realizada al mismo tiempo que se manipula el programa. En la medida en que el usuario aprecie con sus propias manos los recursos que se abren a través de su monitor, el aprendizaje resultará útil y provechoso.

According to the Rajasthan Times (electronic newspaper?), echoed on February 17 2011 by the Archeology Daily Times, a group of anthropologists, working with the tribes of the mountainous and isolated regions of western India, have made a surprising discovery : Intricate Rock Paintings of Extraterrestrials (ET) and UFO-like Ships! The opportunity to return to this idea that, if UFOs have been visiting us for ages, we are entitled to seek their more or less clumsy and stylized representation among the first drawings made by prehistoric men; that is, in rock art representations.
A comparative analysis of the experimental results of the properties of fresh and hardened concrete with different replacement ratios of natural with recycled coarse aggregate is presented in the paper. Recycled aggregate was made by crushing the waste concrete of laboratory test cubes and precast concrete columns. Three types of concrete mixtures were tested: concrete made entirely with natural aggregate (NAC) as a control concrete and two types of concrete made with natural fine and recycled coarse aggregate (50% and 100% replacement of coarse recycled aggregate). Ninety-nine specimens were made for the testing of the basic properties of hardened concrete. Load testing of reinforced concrete beams made of the investigated concrete types is also presented in the paper. Regardless of the replacement ratio, recycled aggregate concrete (RAC) had a satisfactory performance, which did not differ significantly from the performance of control concrete in this experimental research. However, for this to be fulfilled, it is necessary to use quality recycled concrete coarse aggregate and to follow the specific rules for design and production of this new concrete type.
ÖZ Fütüvvet, kavramsal çerçevede tasavvufla sürekli etkileşim halinde ol-muştur. Kur'ân'da, " fetâ " ve türevleriyle geçen fütüvvet kelimesi, peygam-berler ve bazı marifet ehli kişiler için bir unvan olarak kullanılmıştır. Sûfîler de bu sebeple fütüvvet kavramının kökünü, onların örnek hayatlarında ara-mışlardır. Bundan dolayı makalede öncelikle, söz konusu şahsiyetlerin hangi davranışlarına binaen fetâ/ fitye şeklinde anıldığı hususu üzerinde durul-muştur. Ardından da fütüvvet nebevi bir miras olarak ele alınarak, bu ko-nuda yapılan tarif ve yorumlar çerçevesinde, fütüvvet kavramına yüklenen anlamlar tespit edilmeye çalışılmıştır. Bunun sonucu olarak da bu anlam-lardan öne çıkanlar, belli bir tasnif içerisinde değerlendirilmiştir. ABSTRACT The Meaning Attributed to Futuwwa in The Perspective of Sufism Futuwwa, within the conceptual framework, has been in continuous interaction with Sufism. The word of Futuwwa is mentioned as Fata and its derivates in Quran is also used as a title for the prophets and some people of gnosis. For this reason Sufis have looked for the root of the concept of Fu-tuwwa in their examplary lives. So which behaviours of these people made them known as feta/fitye was focused in this article. Then the drew meaning of concept 'Futuwwa' was attempted to determine, according to its prophetic heritage concept within the framework of comments and definitions on it. As a result of that, the highlights of these meanings have been evaluated in certain classification.

The master thesis is focused on ceramic building material (CBM) in Roman and Late Antique Greece. In theoretical part the characteristic, evolution and the life cycle of various ceramic building material is examined, mainly bricks, roof tiles, floor tiles and building accessories. Necessary comparison with western Mediterranean and Byzantine tradition is carried out. Construction techniques using CBM, their advantages and weaknesses are explored with contribution of archaeological data and literary sources. In second part, the case studies from several sites with CBM in Greece are analysed and compared to material studied by author at Priniatikos Pyrgos site (East Crete) with aim to define the main fabric and shape groups, which can help to understand the architectural, economic and social past of the region.

The protection of carpet-rug and other flat fabrics, which are part of our thousands of years of cultural history, is an important problem today. The environment in which organic fabric is located loses its integrity partially or completely according to the time and usage patterns. Therefore, it is of great importance to prevent the loss of cultural heritage and to preserve its integrity with minimal intervention. Wet cleaning refers to the removal of undesired stains or remnants from the surfaces of historical textiles. This article provides an assessment of the development and use of surface active agents for the wet cleaning of historical textiles in Turkey, and makes a review of literature on the active auxiliary surface agents used for the cleaning of historical textiles. The effects of the non-ionic detergent Dehypon® LS54, developed by the British Museum and the Victoria and Albert Museum (V&A), on textiles are examined in detail and taken as a reference. The study uses experimental methods to explain the cleaning processes using STR V18 and STARP 7, developed for wet cleaning purposes as part of the study, focusing on their chemical structures, pH values and effects, and a comparison is made with Dehypon® LS54. For the experiments, woven wool carpet samples were contaminated with artificial stains and were tested under the same conditions. The reflection values of the textile samples were measured using a spectrophotometer, as the results of the experiments. Microscopic images of the relevant samples were taken and any fiber and fabric damage was observed. The removed stain was weighed using a precision scale. The results obtained from the experiments, conducted under the same conditions for the three soaps, were close to one another, and all were successful.

The famous middle Cambrian Burgess Shale was deposited abutting an alleged, near vertical, seafloor carbonate cliff known as the Cathedral Escarpment. The Escarpment is thought to have formed from massive failure of the Cathedral carbonate platform margin resulting in a slide surface with a sub-vertical headwall up to 200 m high. Subsequent retrograde spalling of the headwall has been proposed to explain large carbonate bodies (olistoliths) hosted in adjacent basinal deposits. Field and petrographic observations reveal difficulties with the olistolith/escarpment model ... [partial text]
