Sir Charles Parsons died some three years after the author was born. In this paper the author looks back at the pioneering work of Parsons in the field of power generation. It shows how he was able to increase output of the steam turbine generator from 7.5 kW in 1884 to 50000 kW in 1930 while increasing efficiency from 1.6 to 36 per cent, and relates these achievements to the current state of the art. Blading design, rotor construction and other aspects of turbine engineering are considered. The conclusion is that Parsons and his associates charted the course which manufacturers and utilities throughout the world have continued to follow, although increasingly sophisticated design and analytical methods have succeeded the intuitive approach of Parsons. His constant search for improved efficiency was and is highly relevant to today's concern for the environment. Finally, although it did not become a practical proposition in his lifetime, the paper reviews Parsons' vision of, and continuing interest in, the gas turbine, first mentioned in his 1884 patents.

Carbon Dioxide Co2

Today the world has turned its attention to the phenomena of climate change on the planet. Excess emissions of greenhouse gases (GHG) from human activity are responsible for this change. Gases such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) are part of GHG and have a large capacity to store the energy of the sun in the form of heat, increasing the average temperature in the atmosphere. After the Kyoto treaty, major powers pledged to reduce GHG emissions into the atmosphere, but this practice implies a slowdown in the industrialization and profits of these countries. Countries that can not or do not opt to reduce emissions can buy credits from nations that can generate extra emission reduction values, thus resulting in trade in these credits. Small properties have the potential for credit production, which can generate extra income for the small producer. Therefore, this work aimed at evaluating the potential of commercialization of carbon credits by small properties. The methodology of the work consisted in a systematic literature review on the current state of the art of the proposed theme.

Peritoneal carcinomatosis (PC) is a global challenge of modern oncology representing the most unfavourable scenario in diverse-locality tumourisation. Despite certain attention by the oncological community, the management of PC patients is currently palliative, which weakly promotes research into the basic principles of this morbidity. This literature review attempts to comprehensively cover the PC problematic from a global perspective and presents a key evidence on the world schools of thought in this area. Briefly taking, peritoneal carcinomatosis is viewed today as a local process in the conventional implantation theory, which imposes a locoregional character on all current or emerging therapies, such as cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Their inadequate efficacy is largely due to pronounced gaps in our understanding of PC logistics and signalling. PSOGI is a key organisation for centralising the specialty effort in peritoneal carcinomatosis. Despite its global geography and approach to PC discussion, a multitude of scientific questions remain unanswered impeding the establishment of novel effective therapies. The seven countries that nurtured distinguished schools of thought in PC studies are the USA, UK, Japan, China, Italy, France and Germany. Taking peritoneal carcinomatosis in a global perspective, an insufficient attention to its problematic in Russia should be addressed. The founding and fostering of national PC institutions will benefit cancer patients and progress in oncological science.

Abstract Background Opioids addiction and misuse are among the major problems in the world today. There have been several preliminary studies examining the effect of methadone on depression among addicts, however, these studies have reported inconsistent and even contradictory results. Therefore, the aim of the present study was to determine the effect of methadone on depression in addicts in Iran and around the world, using a meta-analysis approach. Methods This study was a systematic review and meta-analysis including articles published in the SID, MagIran, IranMedex, IranDoc, Cochrane, Embase, ScienceDirect, Scopus, PubMed and Web of Science databases were searched systematically to find articles published from 2006 to March 2019. Heterogeneity index was determined using the Cochran's test (Qc) and I2. Considering heterogeneity of studies, the random effects model was used to estimate the standardized difference of mean score for depression. Subsequently, the level of depression reduction in Iran and worldwide in the intervention group before and after the testwas measured. Results A total of 19 articles met the inclusion criteria, and were therefore selected for this systematic review and meta-analysis. The sample size of the intervention group in the selected studies was 1948. According to the meta-analysis results, the mean depression score in the intervention group was 26.4 ± 5.6 and 18.4 ± 2.6 before and after intervention respectively, indicating the reducing effect of methadone on depression, and this difference was statistically significant (P < 0.01). Conclusion The results of the present study show that methadone significantly reduces depression in addicts. Therefore, regular methadone use can be part of a drug treatment plan.

Dupuytren’s disease is a fibroproliferative disease that involves collagen deposition, leading to hand contractures that ultimately affect hand mobility and grip strength. It is a benign disorder but can cause high morbidity by limiting daily activities. Many factors have been proposed for its aetiology: namely genetics, smoking, alcohol intake and diabetes. However, there is still controversy as to the main aetiological cause of the disease. Treatment is not yet uniform around the world and still varies with the surgeon’s experience and preference. In this review, the authors review the pathogenesis and treatment options for Dupuytren’s disease in an attempt to summarize the current state of the art.

The articles in this special issue demonstrate significant differences in digital archiving capacity in different countries. In part these reflect differences in the history of archaeology in each country, its relationship to the state, whether it is centralised or decentralised, state-led or commercially driven. They also reflect some of the different attitudes to archaeology across the world, most recently explored in a survey conducted under the auspices of the NEARCH project. They reflect a snapshot in time, but our aim is to record the current state-of-the-art in each country, to inform knowledge, stimulate discussion, and to provoke change.

Dendroclimatology has gained relevance during the XXI century. We analyze the state of-the-art of dendroclimatology in Latin America during the past 28 years (1990 to 2019), identifying the current state and recent advances in the application of dendroclimatology in this region. We carried out a systematic review in ScienceDirect, Web of Science, and Scopus databases using Boolean operators to logically connect the keywords &ldquo;dendrochronology,&rdquo; &ldquo;dendroclimatology,&rdquo; &ldquo;trend,&rdquo; &ldquo;climatic variability,&rdquo; and &ldquo;climatic variability trend&rdquo;, for each country. Dendroclimatological research conducted in the region focused on climatic reconstruction and the evaluation of new tree species with dendrochronological potential, which increase in 2010, then there was a gap between 1995 and 1996, later increase to present. Dendroclimatological studies in Latin America have been mainly developed in temperate climate zones (82.4 %) followed by tropical or subtropical areas (17.6 %). Dendroclimatological research in Latin America has provided advances in the study of climate variability by defining response functions of tree rings to climate. The generated information allows for a better understanding of the spatial and temporal dynamics of climatic variability and about its effects on ecosystems and society. We also call for increased dendroclimatological research based on subtropical and tropical forests limited studied until today.

Background: Diabetes is referred to a group of diseases characterized by high glucose levels in blood. It is caused by a deficiency in the production or function of insulin or both, which can occur because of different reasons, resulting in protein and lipid metabolic disorders. The aim of this study was to systematically review the prevalence and incidence of type 1 diabetes in the world. Methods: A systematic search of resources was conducted to investigate the prevalence and incidence of type 1 diabetes in the world. The databases of Medline (via PubMed and Ovid),ProQuest, Scopus, and Web of Science from January 1980 to September 2019 were searched to locate English articles. The located articles were screened in multiple levels of title, abstract,and full-text and final studies that met the inclusion criteria were retrieved and included in the study. Results: From 1202 located articles, 193 studies were included in this systematic review. The results of meta-analysis showed that the incidence of type 1 diabetes was 15 per 100,000 people and the prevalence was 9.5% (95% CI: 0.07 to 0.12) in the world, which was statistically significant. Conclusion: According to the results, the incidence and prevalence of type 1 diabetes are increasing in the world. As a result, insulin will be difficult to access and afford, especially in underdeveloped and developing countries.

Venereal disease is among one of the more active serious epidemics in the world today. Despite its prevalence and the ever-increasing literature on the mathematical treatment of epidemics very little progress has been made toward modelling the spread of this disease. Key features of the disease that help to account for this lack of progress are: (i) VD involves the cross-infection between two groups of individuals and (ii) VD is a recurrent disease. The heterosexual spread .of VD ties in the modelling of this disease with the yet unsolved problem in mathematical biology concerning the growth of two interacting species. In this paper we review the current state of the art in the stochastic modelling of this disease.
