Pyrogeography of savanna fire intensity and severityDaniel Godwin
Fire intensity is considered an important component of our understanding of savannas. Fire intensity can be used to predict probability of top kill of woody stems, and thus can deterministically link fire to demographic bottlenecks observed in savanna woody species. However, our understanding of the spatial processes of fire intensity is limited: What tree neighborhood effects on fire intensity exist? How does intensity vary across woody cover gradients? Is fire intensity really the best metric for understanding impact of fire on savanna plant communities? My research hopes to expand on these topics while suggesting future directions for research and applications in fire management.
Climatological Effects of Total Solar Radiation in Awka, NigeriaIOSR Journals
Harmattan, humidity and temperature are amongst some climatological variables that affect solar radiations. In this paper we evaluated the effects of these climatological variables on solar radiation in Awka, Anambra State, Nigeria. The city Awka has the latitude of 6.06oN and longitude of 7.0oE. We took various readings of temperature and humidity from December, 2012 to July 2013 and we observed as expected that solar radiation increased with increase in temperature, while increase in humidity greatly reduces solar energy. The harmattan effect on solar radiation showed less fluctuations in the value of solar radiation during any particular day. The basic problem during this period is dust, which uniformly reduces the solar radiation during any particular day. Observations during the period of measurement showed that the fluctuations during harmattan and high temperature were essentially due to dust which was responsible for the high diffuse nature and attenuation on the solar radiation. The regression co-efficient for the periods under study in the city were determined for use in predicting solar radiation.

Mapping fire: Can spatially explicit criteria and indicators be developed?CIFOR-ICRAF
Presented by Solichin Manuri, Senior Advisor at Diameter Consulting, Bogor, Indonesia, at "Online Webinar 2: Biophysical Attributes and Peatland Fires", on 14 October 2020
In this session the speaker shared information on mapping fire (extent and occurrences) in tropical peatlands including in Indonesia. This session also shared insights on the existing methods that can be used for fire mapping and comparisons. This session also emphasized that spatial explicit criteria for fire should be developed depending on the method and data used.
Spatial and temporal distribution of forest fire in nepal by Ashok ParajuliAshok Parajuli
Uncontrolled forest fire is an important driver of forest degradation throughout the country. Recurrent forest fires severely damage and prohibit regeneration and growth of seedlings, destroy non-timber forest products and, in some cases, encourage invasive species. Although quantitative information is not available, forest fires are definitely degrading biodiversity, enhancing soil erosion and inducing floods and landslides due to the destruction of the natural vegetation in Nepal. In this study, we scrutinized forest fires activity in Nepal using the Moderate Resolution Imaging Spectroradiometer (MODIS) active fire datasets. We assessed fire magnitude, distribution, seasonality and risk zone in diverse geographical area. MODIS data from 2000 to 2013 revealed an average 2159 fire counts per year with the highest during 2012. Fire season in Nepal extends from January to June with the peak during April. Using Kernel density model, identified hotspot regions of fire in diverse regions of Nepal. Multi-collinearity diagnostic procedure was implemented by examining tolerance and Variance Inflation Factor (VIF). VIF values for each of the predictor were below two, which suggests low or moderate multi-collinearity. These results on forest fires will be useful to stakeholders to address the impact of forest fire in Nepal.
Similar to Fire is not fire: the next generation of TERN fire remote sensing datasets (20)
This publication was endorsed by the National Soils Advocate, The Hon. Penny Wensley AC, on the 8th of December 2022 during the launch of the TERN Australia Soil & Herbarium Collection.
The publication contains the results of 33 interviews with people who, in 2022, have jobs relevant to soils. It is intended for use by secondary and tertiary students who are perhaps wondering what to study or which career might be satisfying - or maybe they have already chosen a soils-related career and are keen to learn something about others who they may meet as lecturers, coworkers or employers.
The booklet will also hopefully be a useful resource for those that assist students with such decisions, including teachers, careers counsellors, guidance officers, librarians, and parents.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
