According to reports of forest range and watershed management organization of Iran, hundreds of forest fires take place in our country every year. Due to destroying forest and grass land in different parts of Iran, especially in Zagross and Alborz Mountain, it is necessary to develop new methods to reduce fire effects in these places. There are many parameters that increase probability of fire occ
ABSTRACT: BACKGROUND: The conditions for steam pretreatment of sugar cane bagasse and leaves were studied using CO2 as an impregnating agent. The following conditions were investigated: time (5 to 15 min) and temperature (190 to 220 degrees C). The pretreatment was assessed in terms of glucose and xylose yields after enzymatic hydrolysis and inhibitor formation (furfural and hydroxymethylfurfural)
Hyaluronan is an unsulfated linear glycosaminoglycan with the ability to nucleate extracellular matrices by the formation of aggregates with lecticans. These matrices are essential during development of the central nervous system. In the prospective white matter of the developing brain hyaluronan is organized into fiber-like structures according to confocal microscopy of fixed slices which may gui
Online shopping is becoming more common. Many consumers prefer to order their groceries online rather than visit an actual physical store, as online shopping is a lot more convenient. Another growing trend in the retailing industry is the increasing number of environmentally conscious consumers who are aware of the impact their actions have. Retailers such as ICA and Axfood are investing quite a l
Amid an anthropogenic sixth mass extinction, amphibians are among the most threatened organism groups. This can be explained largely by the loss and fragmentation of natural wetlands due to agricultural activities and urbanisation. Stormwater retention ponds are designed both to provide flood control and to collect and purify runoff from impervious surfaces but could also serve as amphibian habita
This study utilizes a panel data of 69 developing and developed countries to analyze the impacts of Trade-Related Aspects of Intellectual Property Rights (TRIPS) on the innovation outcomes of the Information and Communication Technology (ICT) sector. The panel analysis is assisted with detailed observations on successful cases that have achieved impressive innovation outcomes over the years, in or
The first coronavirus disease 2019 (COVID-19) outbreak in China and has become a public health emergency of international concern. Several countries have issued comprehensive social distancing policies responses to the pandemic. This study was performed in an attempt to understand the impact of a lockdown on COVID-19 cases through a case study in Scandinavia. A validated database was used to origi
This thesis investigates the influence of country-specific political risk on credit default swap spreads. The research includes a sample of 30 companies over a time period of more than 13 years. The companies are divided into two sets of sub-groups, dependent on whether they are banks or not and which country they are based in. The hypothesis is that banks should be more influenced by political ri
We have recently proposed a statistical AV node model defined by a set of parameters characterizing the arrival rate of atrial impulses, the probability of an impulse passing through the fast or the slow pathway, the refractory periods of the pathways, and the prolongation of refractory periods. All parameters are estimated from the RR interval series using maximum likelihood (ML) estimation, exce
With the use of articles, reports and academic literature, I have analyzed the significant role civil society played during, and after, the Tunisian revolution in 2011. The purpose of this essay has been to understand the underlying social distress, under which Tunisians had lived in many years, and how this came to result in a contagious revolution that marked the start of the Arab Spring. The re
This thesis presents the works on fabrication and measurements done with micro cantilevers and a micro channel system, fabricated in the photo-resist SU-8. SU-8 is a polymer patterned by UV lithography which offers a cheap and fast processing and is an interesting alternative to standard Si techniques. For the structures intended here, it proved to be a well suited material and promising results w
Lotta Granbom, a mother of three from Sweden is on holiday in Thailand. It is her first trip there together with her daughter Ebba-Lotta. After some difficulty finding accommodation at the tourist resorts, they decide instead to search for Sea Nomads in the Andaman Sea. Lotta has heard of a nomadic group of people who live on the sea around Thailand, Burma, Malaysia, Singapore, Philippines and Ind
It is commonly assumed that speech production is initiated and guided by clear pre-verbal intentions. These intentions are moreover supposed to function as a standard of accuracy against which actual performance can be measured. Alternative positions to such a centrally governed process have been offered, but very few empirical attempts have been made to explore the issue. We aimed to remedy this
Aviation fuel is a petroleum product that fulfills the Standard Specification for Aviation Turbine Fuels. Crude oil has been the raw material for production of aviation fuels for many years. Since the availability of crude oil is predicted to be limited in the future, alternative raw materials for aviation fuels are highly desirable. A Swedish company, Oroboros AB, has developed a novel clean synt
This study uses a novel approach to identifying local contextual conditions conducive, alone or in combination to far-right political violence. The studied case is asylum housing attacks occurring in Sweden 2015-16. Using a fuzzy-set qualitative comparative analysis of eighty-six Swedish municipalities, forty-two of which have experienced arson attacks against refugee housing facilities, we operat
In the present study, the operation performance of an ultralow-temperature cascade refrigeration freezer is experimentally researched. The natural refrigerants R290-R170 are adopted as high-temperature and low-temperature fluids. The experimental test is conducted in a type laboratory with a dry bulb temperature of 32.0 °C and a wet bulb temperature of 26.5 °C. Different state monitors are set to
The accuracy and precision of oxygen concentration and temperature measured by dual-broadband rotational Coherent Anti-Stokes Raman Spectroscopy (CARS) were investigated in nitrogen-oxygen mixtures at atmospheric pressure and temperatures between 290 and 1410 K. The relative standard deviation of temperatures evaluated from pure oxygen rotational CARS spectra was found to be around 5%, and the mea
Today, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells. In the process, meat should become healthier, more environmentally friendly and kinder to animals. In this article, I scrutinize (and problematize) this promissory discourse by examining the world that proponents envision alongsidToday, in vitro (Latin: in glass) meat researchers strive to overhaul meat production technologies by producing meat outside animal bodies, primarily by culturing cells.

Sediments from the small lake Ilsø situated in the Illerup/Alken Enge Valley were studied in order to investigate past landscape development at the time of a probably ritual human mass burial following battle during the Roman Iron Age (ad 1–400). A pollen record from Ilsø and a number of other records from Jutland were combined using the Landscape Reconstruction Algorithm to reconstruct local vege
