In the early 1970's, the growing awareness of the potential ecological impacts of fire suppression and the threat of more intensive fires due to fuel accumulation in fire-suppressed forests prompted the National Park Service to allow some fires to burn (Grand Teton National Park 1974). One of the first "prescribed natural fires" in a western National Park was the Waterfalls Canyon Fire (WCF) in Grand Teton National Park (GTNP). It was ignited by lightning in July 1974. Amid much public controversy (Anonymous 1974), the fire burned 1414 ha before it was extinguished by snow in December. In the following year, GTNP biologists established permanent plots within and adjacent to the WCF in forests dominated by subalpine fir, Engelmann spruce, and lodgepole pine, and which varied in fire severity and time since fire. The goal of the study was to document the effect of the 1974 fire by monitoring long-term changes in vegetation, breeding birds, and small mammals (Barmore et al. 1976). Data were collected from four study areas in 1975, 1976, 1977, and 1983 under the direction of William Barmore. In 1991 and 1992 we resampled the permanently-marked vegetation plots and breeding bird transects. Our objectives were to compile, analyze and interpret all of the data collected from the four study areas since 1975.

A major objective of the National Park Service is to preserve examples of natural features and processes that characterize the North American landscape. Fire is now widely recognized as a natural process in many ecosystems, but its management remains a controversial issue. Research on successional change following fire will contribute to improved fire interpretation and management. The Waterfalls Canyon (WC) fire was started by lightning in July 1974 and continued burning until December. Approximately 1414 ha were burned on the west side of Jackson Lake in Grand Teton National Park (GTNP) (Barmore et al. 1976). This fire was especially significant because it was one of the first large fires to occur in a National Park following the adoption of the revised fire management policies in 1972, allowing natural fires to burn in certain designated areas. Prior to 1972, the longÂstanding fire management policy was to suppress both natural and human-caused fires (Barmore et al. 1976). Considerable scientific and public interest was generated by the Waterfalls Canyon fire. For example, tourists in GTNP complained about the smoke which obscured views of the Tetons. For park scientists, the Waterfalls Canyon fire provided an opportunity to initiate studies to better understand and interpret the fundamental role of fire in GTNP. During the summer of 1975, Barmore et al. (1976) established a series of permanent plots to evaluate post-fire changes in vegetation and small mammal and bird abundance. In addition, baseline data were collected in 1975 describing the soils, streamwater chemistry, and insect populations. Permanent plots were established within two stands that burned in 1974: 1) a severely burned stand (forest floor burned exposing mineral soil), and 2) a moderately burned stand (forest floor mostly unburned). In addition, permanent plots were established in two adjacent sites, both unburned in 1974, but which appeared to be very similar to the (WC) burned area. One was a mature spruce-fir forest that had not burned for more than 100 years, and the other was a stand that burned in 1932. Important data was collected by Park scientists following the Waterfalls Canyon fire, with vegetation, bird and mammal data being collected in the four study sites in 1975, 1976, 1977 and 1983.

Implementing appropriate fire regimes has become an increasingly important objective for biodiversity conservation programs. Here, we used Landsat imagery from 1972 to 2003 to describe the recent fire history and current wildfire regime of the north-eastern Simpson Desert, Australia, within each of the region’s seven main vegetation classes. We then explored the relationship between antecedent rainfall and El Niño–Southern Oscillation with wildfire area. Wildfires were recorded in 11 years between 1972 and 2003, each differing in size. In 1975, the largest wildfire was recorded, burning 55% (4561 km2) of the study region. Smaller fires in the intervening years burnt areas that had mostly escaped the 1975 fire, until 2002, when 31% (2544 km2) of the study region burnt again. Wildfires burnt disproportionally more spinifex (Triodia basedowii) than any other vegetation class. A total of 49% of the study area has burnt once since 1972 and 20% has burnt twice. Less than 1% has burnt three times and 36% has remained unaffected by wildfire since 1972. The mean minimum fire return interval was 26 years. Two years of cumulative rainfall before a fire event, rainfall during the year of a fire event, and the mean Southern Oscillation Index from June to November in the year before a fire event could together be used to successfully predict wildfire area. We use these findings to describe the current fire regime.

Changes in fire size, shape, and frequency under different fire-management strategies were evaluated using time series of fire perimeter data (fire atlases) and mapped potential vegetation types (PVTs) in the Gila Aldo Leopold Wilderness Complex (GALWC) in New Mexico and the SelwayBitterroot Wilderness Complex (SBWC) in Idaho and Montana. Relative to pre-Euro-American estimates, fire rotations in the GALWC were short during the recent wildfire-use period (19751993) and long during the pre-modern suppression period (19091946). In contrast, fire rotations in the SBWC were short during the pre-modern suppression period (18801934) and long during the modern suppression period (19351975). In general, fire-rotation periods were shorter in mid-elevation, shade-intolerant PVTs. Fire intervals in the GALWC and SBWC are currently longer than fire intervals prior to Euro-American settlement. Proactive fire and fuels management are needed to restore fire regimes in each wilderness complex to within natural ranges of variability and to reduce the risk of catastrophic wildfire in upper elevations of the GALWC and nearly the entire SBWC. Analyses of fire atlases provide baseline information for evaluating landscape patterns across broad landscapes.

Testo completoAbstract (sommario):
The Vietnam war (1955-75) was a conflict that made its mark on global history. It was a truly multidimensional conflict, where the frontlines were not separate from the heartlands. To bring order to the chaotic situation created by the aftermath of French withdrawal from Indochina, the United States of America decided to involve itself in the pacification of South Vietnam. They wanted to create a stable US-aligned regime which would curtail communist efforts in the region. In order to achieve this, they launched multiple intelligence-gathering and pacification campaigns. But despite the considerable efforts and resources brought to bear, South Vietnam fell to communism in 1975. In this paper, I will give a brief overview of US pacification attempts, and the problems relating to fighting such a difficult battle, where there are no clear sides, and anyone can be a potential enemy. Given the nature of the subject, few such works have been made that attempt to compare the methods listed here.

Testo completoAbstract (sommario):
Wildfire size and frequency have increased in the western United States since the 1950s, but it is unclear how seeding treatments have altered fire regimes in arid steppe systems. We analyzed how the number of fires since 1955 and the fire return interval and frequency between 1995 and 2015 responded to seeding treatments, anthropogenic features, and abiotic landscape variables in Wyoming big sagebrush ecosystems. Arid sites had more fires than mesic sites and fire return intervals were shortest on locations first treated between 1975 and 2000. Sites drill seeded before the most recent fire had fewer, less frequent fires with longer fire return intervals (15–20 years) than aerially seeded sites (intervals of 5–8 years). The response of fire regime variables at unseeded sites fell between those of aerial and drill seeding. Increased moisture availability resulted in decreased fire frequency between 1994 and 2014 and the total number of fires since 1955 on sites with unseeded and aerially pre-fire seeding, but fire regimes did not change when drill seeded. Greater annual grass biomass likely contributed to frequent fires in the arid region. In Wyoming big sagebrush steppe, drill seeding treatments reduced wildfire risk relative to aerial seeded or unseeded sites.

The main objective of this paper is to evaluate whether future climate change would trigger an increase in the fire activity of the Waswanipi area, central Quebec. First, we used regression analyses to model the historical (1973–2002) link between weather conditions and fire activity. Then, we calculated Fire Weather Index system components using 1961–2100 daily weather variables from the Canadian Regional Climate Model for the A2 climate change scenario. We tested linear trends in 1961–2100 fire activity and calculated rates of change in fire activity between 1975–2005, 2030–2060, and 2070–2100. Our results suggest that the August fire risk would double (+110%) for 2100, while the May fire risk would slightly decrease (–20%), moving the fire season peak later in the season. Future climate change would trigger weather conditions more favourable to forest fires and a slight increase in regional fire activity (+7%). While considering this long-term increase, interannual variations of fire activity remain a major challenge for the development of sustainable forest management.

Testo completoAbstract (sommario):
Elephants (Loxodonta africana (Blumenbach 1797)) can have a major transforming effect on savanna structure through felling, debarking or uprooting trees (Dublin et al. 1990, Laws 1970, Mapaure & Campbell 2002). However, it is difficult to separate their influence from that of other causes of tree mortality, including wind storms (Spinage & Guinness 1971), drought (Lewis 1991, van de Vijver et al. 1999), fire (Higgins et al. 2000), and in some situations frost (Childes & Walker 1987, Holdo 2006), especially when interactions among them may occur (de Beer et al. 2006, Laws et al. 1975, Pienaar et al. 1966). Furthermore, the consequences for woodland dynamics depend on the size classes of the trees affected, as well as on how the disturbance is concentrated in time and space. Mortality of canopy trees has a much greater and longer-lasting impact than losses among the regenerating stages of these trees. However, the consequences may be less adverse for ecosystem function and biodiversity if the disturbing effects are locally concentrated, generating a patch mosaic of stands at different stages of regeneration (Remmert 1991).

International Journal of Wildland Fire 26, n. 11 (2017): 930. http://dx.doi.org/10.1071/wf17023.
Testo completoAbstract (sommario):
Multidecadal trends in areas burned with high severity shape ecological effects of fires, but most assessments are limited to ~30 years of satellite data. We analysed the proportion of area burned with high severity, the annual area burned with high severity, the probability areas burned with high severity and also the area reburned (all severities and high burn severity only) over 133 years across 346265ha within the Selway-Bitterroot Wilderness (SBW) Area in Idaho, United States. We used burn severity class inferred from digitised aerial photography (1880–2000) and satellite imagery (1973–2012). Over this long record, the proportion burned with high severity did not increase, despite extensive area burned in recent decades. Much greater area burned with high severity during the Early (1880–1934) and Late (1975–2012) periods than during the Middle period (1935–1974), paralleling trends in area burned. Little area reburned with high severity, and fires in the Early period limited the extent of fires burning decades later in the Late period. Our results suggest that long-term data across large areas provides useful context on recent trends, and that projections for the extent and severity of future fires must consider prior fires and fire management.

Testo completoAbstract (sommario):
Fire frequency in 21 forest planning regions of Portugal during the period 1975–2005 was estimated from historical burnt area maps generated with semi-automatic classification of Landsat Thematic Mapper (TM) satellite imagery. Fire return interval distributions were modelled with the Weibull function and the estimated parameters were used to calculate regional mean, median and modal fire return intervals, as well as regional hazard functions. Arrangement of the available data into three different time series allowed for assessment of the effects of minimum mapping unit, time series length and use of censored data on the Weibull function parameter estimates. Varying the minimum mapping unit between 5 and 35 ha had a negligible effect on parameter estimates, whereas changing the time series length from 22 to 31 years substantially affected the estimates. However, the strongest effect was caused by censored data. Its exclusion led to substantial overestimation of fire frequency and of burning probability dependence on fuel age. We estimated a country-wide mean fire interval of 36 years and an annual burnt area of 1.2%. Regional variations in fire frequency descriptors were interpreted in terms of land cover and land use practices that affect the contemporary fire regime in Portugal.

Testo completoAbstract (sommario):
Assessing wildfire regimes and their environmental drivers is critical for effective land management and conservation. We used Landsat imagery to describe the wildfire regime of the north-eastern Simpson Desert (Australia) between 1972 and 2014, and to quantify the relationship between wildfire extent and rainfall. Wildfires occurred in 15 of the 42 years, but only 27% of the study region experienced multiple wildfires. A wildfire in 1975 burned 43% of the region and is the largest on record for the area. More recently, a large wildfire in 2011 reburned areas that had not burned since 1975 (47% of the 2011 wildfire), as well as new areas that had no record of wildfires (25% of the 2011 wildfire). The mean minimum wildfire return interval was 27 years, comparable with other spinifex-dominated grasslands, and the mean time since last wildfire was 21 years. Spinifex-dominated vegetation burned most frequently and over the largest area. Extreme annual rainfall events (> 93rd percentile) effectively predicted large wildfires occurring 2 years after those events. Extreme rainfall is predicted to increase in magnitude and frequency across central Australia, which could alter wildfire regimes and have unpredictable and far-reaching effects on ecosystems in the region’s arid landscapes.

Testo completoAbstract (sommario):
A series of experimental fires, each 0.4 ha in size, was conducted between 1975 and 1981 in an unthinned stand of immature jack pine (1948 origin) in central Ontario to gather quantitative fire behavior data for forest fire management purposes. Twelve fires were conducted over a broad range of burning conditions. Fire behavior and impact characteristics (i.e., rate of spread, fuel consumption, and frontal fire intensity) were found to be strongly correlated with fire weather severity as expressed through various component codes and indices of the Canadian Forest Fire Weather Index (FWI) System. This type of experimental fire information, along with wildfire data, is being used in the development of guidelines for quantitative prediction of fire behavior in major Canadian forest fuel types.

Testo completoAbstract (sommario):
In fire-prone areas, like the Mediterranean, land abandonment and forestation may interact with fire to alter landscape properties and eventually fire hazard and occurrence. However, the spatial interactions among the two processes (land-use/land cover change [LULC] and fire) are poorly known. Here, we analysed the relative effect of LULC change and fire on the landscape structure of an area of Central Spain frequently affected by fire. A series of Landsat MSS images from 1975 to 1990 was analysed to quantify annual changes in LULC, map fire perimeters and evaluate the changes in landscape properties. The temporal dynamics were analysed by annually computing the fraction occupied by each LULC type and landscape structural properties (number, size, shape and arrangement of patches) that might play a role in fire propagation. All of these were calculated separately for the unburned or the burned areas during the study period, as well as for the entire area. At the whole landscape level, or in the unburned area, LULC changes were small, yet the two more flammable LULC types tended to increase, and the landscape tended to become more homogeneous. In the burned area, the area covered by pine woodlands tended to decrease, and that covered by shrublands to increase. Burned areas turned into shrublands only five years after fire. Landscape indices indicative of reduced fragmentation were also found. Both LULC change and fire altered landscape patterns in the whole area to create a less fragmented and more contiguous landscape than in 1975. The changes induced in the whole landscape by fire, in spite of the overall low disturbance rate, were sufficient to closely determine the changes in landscape composition (LULC types) and patterns.

Testo completoAbstract (sommario):
The transport of stream bedload sediment was monitored continuously in a small stream from 1975 to 1982 following forest fires in 1974 and 1980. The stream is located in the east subcatchment (170 ha) of Lake 239 in the Experimental Lakes Area, northwestern Ontario. Precipitation, stream discharge, bedload transport, and concentration of suspended materials were measured quantitatively and organic debris was observed and collected. Bedload transport increased 20-fold following the first fire and threefold after the second. Particle sizes tended to increase during the period of study. Bedload data suggest a recovery period of 5–6 yr following the first fire and a shorter one following the second. A mass budget of material load transported in a single year following recovery indicated a dominance of dissolved load (87%), followed by suspended load (10%), and bedload (3%).

Testo completoAbstract (sommario):
The relative influence of the factors acting on burn probability, namely fuel and weather, is not well understood, especially in Europe. We use a digital fire atlas (1975–2008) and apply survival analysis to individual fires (1998–2008) to describe how burn probability changes with fuel age in Portugal. The typical fire return interval and median fire-free interval vary regionally from 23 to 52 and 18 to 47 years. Increase of the hazard of burning with time is generally near-linear, denoting moderate fuel-age dependency, as in some other shrub-dominated Mediterranean environments. Analysis of complete fire intervals resulted in shorter fire return interval and higher fuel-age dependency of burn probability than findings that included censored observations. Increasingly severe weather conditions either expressed through fire size or by extreme fire danger concurrently decreased fuel-age dependency and selected older fuels. The results are discussed from the viewpoints of fire suppression and fuel treatments.

Testo completoAbstract (sommario):
This paper estimates fire frequency in Catalonia (NE Spain) for the last quarter of the 20th Century (1975–1998) from historical burned area maps. Remote sensing images provided perimeters of fires ≥ 30 ha, which were used to characterize the temporal patterns of fire occurrence in Catalonia. Several fire frequency models were used to reproduce the observed pattern of wildfires occurrence in the study period. Natural fire rotation period was estimated to be 133 years. Poisson tests were carried out to check random fire occurrence either along the time period or across the analysed region. Observed fires were not randomly generated either in space or in time, despite being sampled using two different plot sizes. This sampling design was also used for Mean Fire Interval (MFI) analysis, which allowed us to significantly fit a Weibull distribution to the observed proportion of fire intervals (for both sample sizes), enabling us to estimate the hazard of burning, mortality, and survivorship functions. Finally, MFI was also applied to forest regions of Catalonia, which are defined according to forest management plans based on their homogeneous climatic conditions. Such an analysis revealed relevant differences in forest management and their consequences on fire occurrence.

Testo completoAbstract (sommario):
Under severe fire weather conditions arson is believed to be the primary cause of large wildland fires in southern California. Wildland fire suppression personnel and the public use the the expression "This weather brings out the arsonists" to indicate their awareness of the high potential for large arson-caused fires under these conditions. To determine the accuracy of this statement, fire occurrence and weather data were analyzed for four southern California National Forests for a 10-year period (1975–1984). The results showed that the proportion of arson and non-arson person-caused fires remained the same under most fire-danger conditions; however, a much higher percentage of arson fires became large fires when fire danger was severe. Furthermore, the timing of the arsonist contributed to the frequent occurrence of large arson fires. The data presented here refute the idea that most arson fires occur under severe weather conditions and at the same time-validate the utility of maintaining arson prevention programs during most weather conditions.

The spatial distribution of the monthly mean values for various climatological parameters in Northern Greece is derived. The corresponding data come from measurements at several meteorological stations located in Central Macedonia, Eastern Macedonia, and Thrace (CM/EMT) area in the period 1975–1997. The collected data concern high temperature and low relative humidity, as well as local forest coverage, and are utilized for the calculation of a modified Fosberg Fire-Weather Index in order to estimate the fire risk over Northern Greece due to the local weather under critical conditions. As a result, monthly fire-risk maps of the CM/EMT area for the months of May to October are derived for the first time by applying sophisticated analytical geospatial tools and methods. Furthermore, fire events corresponding to the same region and period are added to the derived maps for comparison and for a better evaluation of the method. The resulting correspondence of the predicted fire risk to the local wind-speed behavior and forest abundance demonstrates the need of the necessary precaution measures to limit the future danger levels from fire events.

Testo completoAbstract (sommario):
Fire regimes in Mediterranean countries have been shifting in recent decades, including changes in wildfire size and frequency. We sought to describe changes in fire regimes across two periods (1975–1995 and 1996–2018) in a fire-prone region of central Portugal, explore the relationships between these regimes and territorial features, and check whether these associations persisted across periods. Two independent indicators of fire regimes were determined at parish level: fire incidence and burn concentration. Most parishes presented higher values of both indicators in the second period. Higher values of fire incidence were associated with lower population densities, lower proportions of farmland areas and higher proportions of natural vegetation. Higher levels of burn concentration were associated with smaller areas of farmland and natural vegetation. These associations differed across periods, reflecting contrasting climatic and socio-economic contexts. Keeping 40% of a parish territory covered by farmland was effective to buffer the increased wildfire risks associated with different management and climate contexts. The effectiveness of higher population densities in keeping fire incidence low decreased in the last decades. The results can improve the knowledge on the temporal evolution of fire regimes and their conditioning factors, providing contributions for spatial planning and forest/wildfire management policies.

AbstractThe term forest fire risk means the existence of such conditions that would make possible the occurrence of a fire in the forest environment. The base for the effectiveness of a forest fire protection system is the evaluation of the forest fire risk followed by adequate organization of the system. This article presents methods for determination of the forest susceptibility to fire known as potential forest fire risk. The below presented methods were developed by Forest Research Institute as the results of the projects commissioned by the General Directorate of State Forests. The forest fire risk category and stand flammability classes are the methods included here. The forest fire risk category was elaborated already in 1975 for the first time. Until today, after the last modification in 2008, it is the fundamental document for the polish forest fire protection system. The purpose of this modification was to increase the determination accuracy of the fire risk category of all polish forest, regardless of its ownership type and at the different administrative level. The categorization method, however, doesn’t reflect the fire risk in micro scale. The attempt to solve that problem was made in 2018 while developing the methodology of stand flammability classes. It was assumed that ground cover fuel models will be developed for the most flammable forest habitat types including ground cover types, dominant species, age class and geographical localisation.

Testo completoAbstract (sommario):
This study used simulation modelling to investigate fire and carbon dynamics for projected warmer and drier climates in the south-eastern Australian high country. A carbon accounting model FullCAM and the landscape fire regime simulator FIRESCAPE were combined and used to simulate several fire management options under three climate scenarios – the recent climate (1975–2005); a moderate climate projected for 2070 (B1); and a more extreme climate projected for 2070 (A1FI). For warmer and drier climates, model simulations predicted (i) an increase in fire incidence; (ii) larger areas burned; (iii) higher mean fire intensities; (iv) shorter fire cycle lengths; (v) a greater proportion of fires burning earlier in the fire season; (vi) a reduction in carbon stores; (vii) a reduction in carbon sequestration rates; and (viii) an increase in the proportion of stored carbon emitted to the atmosphere. Prescribed burning at historical or twice historical levels had no effect on fire or carbon dynamics. In contrast, increasing the initial attack success (a surrogate for suppression) partially offset the adverse effects of warmer and drier climates on fire activity, but not on carbon dynamics. For the south-eastern Australian high country, simulations indicated that fire and carbon dynamics are sensitive to climate change, with simulated fire management only being able to partially offset the adverse effects of warmer and drier climate.

Testo completoAbstract (sommario):
Total area burned yearly in Portugal in the period of 1975 to 1992 is related to rainfall during particular periods of the year. Precipitation in the period of January to April, corresponding to Winter and early Spring, related to fine fuel growth and to the water reserve in the soil, shows a non monotonic relationship with burned area each year, due to the conflicting mechanisms of the these two processes. Rainfall between June and September, corresponding to the main fire season in Portugal, exhibits an inverse relation with burned area. Data of a single weather station were used in the analysis and it was demonstrated that they are representative of a wide area in the country.

ABSTRACT The worst outcome of wildland fires is the loss of human lives, a recurrent phenomenon over the last few decades in Sardinia, Europe and worldwide. This work analyzes all recorded fatalities in wildland fires in Sardinia from 1945 to 2015 and trends in terms of annual number of fatalities. This time period was split due to legal and socioeconomic changes periods (1945-1975; 1976-2000; 2001-2015). We classified accident types during wildland fires to study the most frequent causes of fatalities and how they were related 1) to involved human groups (professional firefighters, auxiliary firefighters, and civilians, 2) to fire size and 3) to extreme weather conditions. We observed that the annual number of victims was higher in the 1981-1999 period than in other periods with 2.6 fatalities per year. Entrapment is the most frequent cause of death within the fire professional firefighters (75.6 %). The rate of fatalities seemed to be higher in the 1981-1999 period for “civilians” and lower for “professional firefighters”. We detected that the annual number of “civilian” fatalities is higher in the 1981-1999 period with 1.6 fatalities per year. The calculated rate for “army forces & volunteer firefighters” group was in the middle ground. Entrapment is the most frequent cause of death with a percentage of 75.6 %. Fire size is a key factor in the fatality occurrence because over 80 % of deaths in wildland fires (without considering aerial accidents) happened in fires larger than 100 ha. Days with extreme weather conditions (high temperature or strong winds) were also instrumental because at least 47% of entrapments occurred in this kind of days.

The aim of this article is to retrace a guerrilla episode that occurred in the Amazon region of Araguaia during the military dictatorship in Brazil (1972?1975), opposing a group of militants from the Communist Party of Brazil (PCdoB) and the National Brazilian Army. Taking advantage of the geographical characteristics of the region, a small group of guerrilla fighters was able to confront a large military contingent for almost three years. As this article demonstrates, appealing to the powerful symbolic potential of the Amazon jungle, the guerrilla created a solid environmental narrative of force and shrewdness supported by the local population. However, as military forces began to better explore the region and to resort to irregular warfare strategies, they managed to curb the guerrilla, exterminating almost every member involved in the fight. Finally, this article looks at the marked socio-environmental scars that the conflict left in the region, and how these influenced social, political and ecological equilibriums during the following decades.

Testo completoAbstract (sommario):
The temperature fields within twelve concrete filled steel tubular columns with or without fire protection when exposed to the ISO-834 standard fire curve (ISO-834, 1975) have been experimentally investigated and the results are presented in this paper. The main parameters varied in the tests are: (1)Sectional types, square and circular; (2) Sectional dimensions from 299mm to 800mm; (3) Thickness of fire protection coat from 14mm to 35mm. A derivation has been given for the surface temperature of concrete-filled tubular columns. Nonlinear finite element analysis has been carried out to calculate the temperature field for the members with and without fire protection. The theoretical predictions are in good agreement with the experimental data. It has been found that the increasing of tube dimensions results in a temperature reduction in the section. The effect of tube dimensions on temperature reduction is more significant for the core concrete than for the steel surface. Within a three-hour fire time, the reduction in temperature due to the increase in tube dimensions becomes less significant when the outer sectional dimension exceeds about 400 mm. The work in this paper provides a basis for further theoretical study on the fire resistance of concrete filled steel tubular columns.

The first earthquake code in Turkey was enacted in 1944. Revisions were issued in 1949, 1953, 1961, 1968 and 1975. At the time of March 13, 1992 Erzincan earthquake, the seismic resistant design code in effect was the code adopted in 1975, Specifications for Structures to be Built in Disaster Areas. The code has provisions for other disasters—avalanches, landslides, floods, and fire—in addition to earthquakes. The code was prepared under the auspices of and issued by the General Directorate of Disaster Affairs of the Ministry of Public Works and Settlement (formerly Ministry of Reconstruction and Resettlement) and enacted into law by ruling of the Council of Ministers. The complete code is included in the latest issue of Earthquake Resistant Regulations: A World List, published by the International Association for Earthquake Engineering (1988). A draft of revisions to the 1975 Turkish building code is currently in the final review process. This proposed code revision was being circulated for review at the time of the March 13 earthquake.

Testo completoAbstract (sommario):
AbstractThis article focuses on the documentary The Songs of Fire by Nikos Koundouros (1975). Shot immediately after the fall of the military dictatorship (1967–74) in Greece, it exhumes the elation of three public concerts and demonstrations, capturing the enthusiasm for the return to democracy expressed through singing and chanting. The article focuses on the ways in which popular songs became the vehicles of the popular demand for democracy during the early transition to democracy. It shows how the film was crucial in establishing a narrative of resistance in collective memory that was centred on singing and listening, investigating the ways in which this sonic narrative, performed collectively and publicly, also betrays a latent reaction to a brutal regime fought by the few. It argues that collective singing seems to merge in memory with the ‘singing resistance’ performed individually and in secret during the dictatorship. Extended back in time, this sonic narrative registers an unconscious desire to repress the fact that large parts of society had remained silent during the regime's seven-year rule.

Abstract This article examines the brilliant caricatures by Nikolai Vladimirovich Remizov (Re-mi, born Vasil’ev, 1887–1975) for the Russian satirical journals of 1905–1907. This period marked the first stage of Remizov’s long career, when he emerged as one of the country’s most talented and well-known caricaturists. The article focuses on Remizov’s new, no-holds-barred satire depicting episodes of state-sponsored bloodletting. The satirical journals widely quoted the words of Dmitri Trepov to his troops during the October general strike “not to fire blanks and to spare no cartridges,” a phrase that became a tragi-comic mantra in the satirical journals. It also reflected the take-no-prisoners spirit of Remizov’s caricatures. Further, the article outlines Remizov’s subsequent participation in the few journals—in particular, Satirikon and Novyi Satirikon (New Satyricon)—that strove to keep the satirical tradition of 1905 alive. After the Bolshevik Revolution put a forcible end to these publications, Remizov emigrated, and later forged a long career in the United States as an art designer for stage, television and the big screen.

This study was conducted to determine how secondary schools in Kilimanjaro region were prepared to administer first aid to casualties of fire disasters. This study was guided by the Protection Motivation Theory (1975) and employed a convergent research design under mixed methods research approach. The study sample was obtained through stratification. The study revealed among other things, that most schools had first aid kits facilities, offered guidance and counselling services and respondents were confident enough to administer first aid. The study concluded that secondary schools had to a great extent prepared to administer first aid to casualties of fire disasters, if such menaces occurred in schools. The study recommended inter alia, for more training on first aid in secondary schools.

The ubiquity of high-quality video surveillance owes much to advancements in imaging technology and data transmission. Presently, exposing an individual’s face in photographs can infringe upon their right to privacy. Real-world face de-identification is a typical task beyond removing private information, considering the specific intent behind image usage. This paper introduces a novel deep learning model (NDLM) designed to safeguard facial privacy in video surveillance, structured around two key phases: face detection and privacy protection. Initially, surveillance video data is collected from online sources. In the initial phase, face detection is achieved through the integration of a Hybrid Convolutional Neural Network (HCNN), which combines a convolutional neural network (CNN) and the improved Fire Hawks algorithm (IFHA) for optimal performance. IFHA assists in ensuring privacy protection. This integration incorporates service quality preservation into the loss function, facilitating the generation of facial images with controlled quality preservation. The approach effectively manages various service quality measures and is adaptable across diverse service contexts. The proposed methodology’s effectiveness is evaluated to demonstrate its efficiency when compared to traditional methods.

An exercise undertaken in this article has unravelled the status of forest offences in Himachal Pradesh from 1965-66 to 2009-10. It brought out that a total of 10,39,172 no. of forest offences (average 23093 annually) were taken cognizance of in the State from 1965-66 to 2009-10. The highest no.of offences ( 43901 no.) were detected in 1975-76 and the lowest (11869 no.) in the year 2006-07. Illegal felling & grazing related offences together constituted nearly 57%, forest fire related offences were less than 2% whereas the miscellaneous offences were nearly 40% of the total. The period from 1971 to 1985 experienced sharp increase in the number. of forest offences, though the offences taken cognizance of were disposed off quite efficiently. The rate of disposal ranged from 71.88% to 80.13% during various time periods from 1965-66 to 2009-10 with overall disposal rate of 77.52 % Of the total no. of offences disposed off 9.3% of the cases were taken to Courts/ authorised officers and 78.4%. were disposed off by way of compounding, 13.23% remained untraced/filed. Periodic trend (5 year blocks i.e. P1 to P9) revealed 50% decline in forest offences during P-9 (2005-2009) compared to what existed during P-1(1966-70). Ironically the downturn was despite tremendous increase in human and domestic animal population in the State during same time. The success rate of the offences decided by Courts/ Authorised officers ranged from 76.92% during-P-1(1965-69) to 98.9% during P-9(2005-09) as per data published by State Forest Department. On the other hand, cases registered with Police from 1988 to 2015 secured conviction rate of 12.99%.

Testo completoAbstract (sommario):
We characterize fire regimes in central Portugal and investigate the degree to which the differences between regimes are influenced by a set of biophysical drivers. Using civil parishes as units of analysis, we employ three complementary parameters to describe the fire regime over a reference period of 44 years (1975–2018), namely cumulative percentage of parish area burned, Gini concentration index of burned area over time, and area-weighted total number of wildfires. Cluster analysis is used to aggregate parishes into groups with similar fire regimes based on these parameters. A classification tree model is then used to assess the capacity of a set of potential biophysical drivers to discriminate between the different parish groups. The results allowed us to distinguish four types of fire regime and show that these can be significantly differentiated using the biophysical drivers, of which land use/land cover (LULC), slope, and spring rainfall are the most important. Among LULC classes, shrubland and herbaceous vegetation play the foremost role, followed by agriculture. Our results highlight the importance of vegetation type, availability, and rate of regeneration, as well as that of topography, in influencing fire regimes in the study area, while suggesting that these regimes should be subject to specific wildfire prevention and mitigation policies.

The small, oil-rich state of Brunei (population c. 40,000 in 1940) is situated in north-west Borneo. The ‘Abode of Peace’ became a British protectorate in 1888 and a Residential System along Malayan lines came into operation at the beginning of 1906. For most of the Second World War the country was under Japanese Military Administration, a period of three and a half years beginning in December 1941. Allied, predominantly Australian, landings took place in early June 1945 (Fahey 1992: 325–8; Monks 1992: 7–53) and the sultanate was speedily cleared of enemy forces, though not before the latter had successfully executed a scorched-earth programme. Most crucially of all, the Seria oilfield (discovered in 1929 by the Shell company) was set alight, the flames shooting ‘like giant blow-lamps’ at least thirty feet into the air. The last well fire was not extinguished until 27 September 1945 (Harper 1975: 21–4). A report in the Straits Times of 20 July 1946 gives some impression of the problems faced by the returning Western engineers:Most of the [Seria] wells were surrounded by blazing lakes, and the oil experts had to blast their way through. Because of the intense heat it was difficult to get near enough to ‘cap’ them and so seal the fires. In some cases aircraft were used, the fire-fighters advancing through the slipstream of the propellers which blew the flames and oil back. It then became possible to get near enough to thrust forward on long steel arms heavy charges of explosives.

America’s underground economy has grown strikingly since the 1970s, reflecting consumer demand for cheap prices, workers’ search for alternative sources of income, and government intervention. Far from unregulated, this economy has been managed in crucial ways, revealing a fundamental paradox in free market rhetoric. This was particularly striking in New York City in the latter decades of the twentieth century, where a set of uneven responses to the underground economy expanded its boundaries through new licensing, zoning, and permitting requirements that many businesses could not conform to. A tragic fire at an immigrant social club in March 1990 revealed the problematic turns in municipal policy taken in the aftermath of the city’s fiscal crisis. The lead up and response to the Happy Land Social Club fire by city officials demonstrated a rise in punitive regulation aimed at New York’s marginalized residents in an era of alleged deregulation and small government fetish.

Testo completoAbstract (sommario):
The noisy scrub-bird Atrichornis clamosus at Two Peoples Bay was censused, the number of singing males being used as the population index. Incomplete data from 1962 to 1968 suggest that the number of males varied from 40 to 50 during this period. The first rigorous census found 45 males in 1970 and this number increased to 138 in 1983. The most likely reason for this increase is the absence of fire from the area since 1970. Since 1975 the population has expanded out of its headland stronghold to the south-west of Two Peoples Bay to form a subpopulation around Lake Gardner that is well separated from the headland population by roads, firebreaks and a strip of control burnt blocks. The growth of this subpopulation has added a further safeguard to the population. Observations on the vegetation formations (heath, thicket, low forest A and low forest B) used by male noisy scrub-birds on the headland indicate that most of the best habitat (low forest B) is occupied and that an increasing number of males are occupying suboptimal habitat (heath and thicket). There is sufficiently good habitat to the west of Lake Gardner to allow at least 30 additional males to live in the area.

Siberian peatlands provide records of past changes in the continental climate of Eurasia. We analyzed a core from Mukhrino mire in western Siberia to reconstruct environmental change in this region over the last 1300 years. The pollen analysis revealed little variation of local pine-birch forests. A testate amoebae transfer function was used to generate a quantitative water-table reconstruction; pollen, plant macrofossils, and charcoal were analyzed to reconstruct changes in vegetation and fire activity. The study revealed that Mukhrino mire was wet until the Little Ice Age (LIA), when drought was recorded. Dry conditions during the LIA are consistent with other studies from central and eastern Europe, and with the pattern of carbon accumulation across the Northern Hemisphere. A significant increase in fire activity between ca. AD 1975 and 1990 may be associated with the development of the nearby city of Khanty-Mansiysk, as well as with the prevailing positive Arctic Oscillation.

Wildfires affect the structure and distribution of vegetation all over the globe and have their own specifics in different regions. In this study, we considered the spatial and temporal distribution of fires in the Jewish Autonomous Region (JAR), which is the most fire-prone area of the Russian Far East. Using data from the Department of Natural Resources of the Jewish Autonomous Region, fires and burned areas for more than 40 years were analyzed. The average annual number of fires is near 100, and the average area of one fire is 134 hectares, which is significantly higher compared to other regions of Russia. The largest number of fires and fires with the greatest extent took place in 1975. The intra-annual distribution of fires is bimodal and depends on the climate characteristics of the region. Mapping of burning areas showed that most of the fires occurred near settlements and along roads. The main centers of fire ignition were areas with a large number of small fires (no more than 5 hectares), located within several types of locations: (1) asphalt and dirt roads, railroads and river valleys near settlements; (2) areas of former logging that have several large burned spots of more than 300 hectares; (3) plains with a high concentration of fires over a large region; and (4) small burned spots on the mountain slopes, along the field roads and small rivers. Regions with different degree of fire exposure were identified. Sedge-reed mixed grassy meadows and Agricultural land with shaded meadows are the plant formations most prone to wildfires. At the same time, more fires were detected in Cedar-deciduous forests as well as Oak and black birch forests. The findings are useful for environmental protection agencies in planning fire management strategies, optimizing the fire services and firefighting actions.

Ten years ago it seemed that the genius of Canadian theatre could be summed up in two words: collective creation. The post-colonial nationalism of the 1970s spawned hundreds, if not thousands, of collective shows that transformed the theatre in this country to an extent that we have just begun to comprehend. 10 Quebec, high noon for the collective movement came in 1975 when a faction of radical troupes engineered a schism in L’Association quebecoise du jeune theatre that redefined the politics of collective creation. 10 English Canada the vogue of down-home collective documentaries reached its zenith somewhat later with the prairie-fire national tour of Paper Wheat in 1978

Abstract The restoration of the ruins of the Abbey-Tower in the city centre of Sint-Truiden in Belgium is presented as an example of the tedious and comprehensive task involved in all restoration or rehabilitation projects, where the extra cost of the restoration must be justified by the added value connected with the conservation of authenticity and with the contribution to sustainable development. The development and evolution of the project took 28 years, between the damages caused by the fire in 1975 and the start of the restoration in 2003. Since 2004, the restored ruin started a new life as a beacon of the city of Sint-Truiden, highly appreciated by tourists as well as by the inhabitants.
