René Ramírez Fernández, of notable academic experience, in his role as Coordinator and one of the authors of the book, achieves in the compilation that the researchers show their awareness for the care of the environment and their visible concern for the abuse of non-renewable energies advocating, with scientific argument, for an energy balance for Colombia, promoting an energy transition, for the use of renewable energies and the use of biodigesters for the reduction of the carbon footprint. It should be noted that each of the contributions that you will find in the book are the result of research that has had as a starting point the collection of information, the analysis of real statistical data and the use of a methodology that ensures that the conclusions that are socialized in each of the four chapters of the book are important contributions that have a scientific support.

This open access book, written by world experts in aquaponics and related technologies, provides the authoritative and comprehensive overview of the key aquaculture and hydroponic and other ...integrated systems, socio-economic and environmental aspects. Aquaponic systems, which combine aquaculture and vegetable food production offer alternative technology solutions for a world that is increasingly under stress through population growth, urbanisation, water shortages, land and soil degradation, environmental pollution, world hunger and climate change.
This open access book richly illustrates the first, and comprehensive, account of the country’s biomes and ecoregions, the driving forces that account for their diversity and vulnerability, and the ...ecological principles that provide an understanding of the patterns and processes that have shaped landscapes, ecoregions, and ecosystems. Angola encompasses the greatest diversity of terrestrial biomes and is the second richest in terms of ecoregions, of any African country. Yet its biodiversity and the structure and functioning of its ecosystems are largely undocumented. The author draws on personal field observations from over 50 years of involvement in ecological and conservation studies in Angola and across Southern Africa. The vast recent literature published by researchers in neighboring, better resourced countries provides depth to the accounts of ecological principles and processes relevant to Angola and thus contributing to the understanding and sustainable management of its natural resources.

Earth building is not only one of the oldest, but also one of the most modern construction methods of our time. What economic, environmental, and social conditions are necessary to make this building ...method more attractive? In the future, cement – the most important component of concrete – will, like other finite resources, become less viable to produce and significantly more expensive. Considering appropriate alternatives for building materials is imperative. This book presents a wide range of built and unbuilt projects as well as strategies for architecture using earth materials – a construction method that can be adapted to every culture and context. The authors give impressive examples to demonstrate groundbreaking technological innovations that highlight the advantages of this material, from its worldwide availability to its potential for complete recycling and climate-neutral production. The book also includes a focus on socially just implementation, in particular in emerging economies. This book reveals the incredible potential of earthen architecture – for people and for the entire planet.
Ciljevi: Svrha ovoga rada bila je odrediti postotak perzistentnih apikalnih lezija pozitivnih na bakterijske nukleinske kiseline, zatim s pomoću lančane reakcije polimeraze detektirati mikroorganizme ...u periapikalnim lezijama koje je teško kultivirati te ih povezati s endodontskim neuspjehom, kliničkih simptomima i dijabetesom. Materijali i postupci: Uzorci perzistentnih apikalnih lezija skupljani su tijekom apikotomije. Bakterijska ubikvitarna početnica 16S rRNK rabljena je za otkrivanje 16S ribosomskog RNK u 36 uzoraka. PCR usmjeren na pojedine vrste proveden je s pomoću početnica za 16S rRNK gene Prevotelle nigrescens, Pseudoramibactera alactolyticusa i Propionobacterium propionicum. Rezultati: Šest uzoraka (16,67 %) bilo je pozitivno na bakterijski ribosomski RNK. Pseudoramibacter alactolyticus detektiran je u trima uzorcima. Propionibacterium propionicum i Prevotella nigrescens detektirani su svaki u po jednom uzorku. Prevalencija infekcije ovih lezija P. intermedia, P. propionicum i P. alactolyticusom niska je. Provedeno istraživanje nije dalo dostatne podatke o povezanosti ekstraradikularne infekcije s dijabetesom melitusom i kliničkim simptomima. Zaključci: Apikalne lezije koje perzistiraju nakon endodontskog liječenja mogu, uz Actinomyces i Propionicum species, sadržavati i druge mikroorganizme.
Grupirane pravilno razmaknute kratke ponavljajuće palindromske sekvence (CRISPR)/CRISPR-povezani sustav (Cas) je sustav koji osigurava imunost većine prokariotskih organizama na napade virusa i ...drugih stranih tijela. CRISPR sustavi se sastoje od bjelančevine nalik škarama naziva Cas9 i genetskog GPS vodiča „vodičke RNK“. Međutim, istraživači su preorijentirali i prenamijenili iskonski imunološki sustav za preciznu manipulaciju genomom u većini organizama uvodeći dvolančane lomove na DNK na određenim lokacijama genoma radi uvođenja specifičnih izmjena DNK.
Od njegova otkrića CRISPR ima sve više primjena; od onemogućavanja parazita do ispravljanjamutacijaipoboljšavanjaprinosa u poljoprivredi. Ovo istraživanje provedeno je da bi poslužilo kao vodič za CRISPR tehnologiju, od povijesti njegova otkrića do najnovijih saznanja. Nadamo se da će ova studija osigurati općeniti pregled ove tehnologije koja mijenja živote, a i inspirirati znanstvenike da nastave istraživanja s CRISPR-om, za bolji život.
This open access book is one in a series of four volumes introducing peatland conservation and restoration in Indonesia. It focuses on local governance, in particular on regional and local ...perspectives in Riau, the most peat-destructed province of Indonesia. The book fills a vital gap in the existing literature that overlooks social science and humanities perspectives. Written by authors from different disciplines and backgrounds (including scholars and NGO activists), the approaches to the topic are various and unique, including analysis of GPS logs, social media, geospatial assessments, online interviews (conducted due to the Covid-19 pandemic), and more conventional questionnaires and surveys of community members. The chapters cover an interdisciplinary understanding of peatland destruction and broadly offer insights into environmental governance. While presenting combined studies of established fieldwork methodologies and contemporary technology such as drones and geospatial information, the book also explores the potential of long-distance research with rural communities through online facilitation, which was brought about by Covid-19, but that may have longterm implications. Readers will gain a comprehensive understanding of the complexities surrounding peatland conservation and restoration and recognize the significance of locally inclusive approaches that use contemporary but accessible technologies to sustainably govern the globally important resource of peatland. That approach would be useful for other environmentally fragile but important regions and give some ideas to achieve the United Nations’ SDGs for 1)No Poverty, 5)Gender Equality, 13)Climate Action, 15)Life of Land.
