1. A forest is defined as an area of land with a minimum size of 0.5 hectares that has a tree canopy cover of more than 10% and trees that can reach a minimum height of 5 meters.
2. Forestry involves the science, art, and practice of managing and conserving trees, forests, and their resources. It aims to obtain maximum outputs from forests through silviculture and management techniques.
3. Key terms in forestry include canopy, species composition, stand, regeneration, logging, rotation, and clear-cutting. Forestry involves the management of forests for purposes like wood production, wildlife conservation, and recreation.
This presentation provides an overview of a field-based practical exercise that allows students in forestry, ecology and natural resources to develop their understanding of forest stand dynamics. The exercise involves measurement of key tree growth parameters in four even-aged, single-species plantation stands of different age but occupying sites with similar soil and environmental characteristics. The selected stands represent key stages in stand development, from establishment to rotation age for fibre production. In the field, students work in small teams to gather data from an equal number of plots within each stand. Tree parameters include top height, crown diameter, live crown ratio and diameter at breast height. In addition, information on stand density and understorey vegetation is collected. Plot size and number can be varied to suit the constraints of class size and available time, though circular plots of 100 m2 are recommended. In the classroom, data are pooled and analysis focuses on presenting tree and vegetation changes through time. The simplest way of interpreting the data is to prepare graphs and charts for each of the parameters, though more advanced statistical interpretations are possible. The project as outlined here can be modified to meet the needs of different groups, and has been successfully used in undergraduate teaching of silviculture and forest ecology, as well as in postgraduate courses in natural resources management.

Agroforestry: A Comprehensive Analysis of its Importance
Introduction:
Agroforestry is a sustainable land management practice that integrates trees, crops, and/or livestock on the same piece of land. It is a multifunctional approach that combines elements of agriculture and forestry to create a harmonious and productive ecosystem. This essay delves deep into the significance of agroforestry, exploring its ecological, economic, and social importance in the context of modern agriculture and environmental conservation.
Ecological Importance:
1. Biodiversity Conservation: Agroforestry systems promote biodiversity by providing diverse habitats for various species. Trees and crops together create microhabitats that support a wide range of flora and fauna, enhancing ecosystem resilience.
2. Soil Health and Erosion Control: Tree roots stabilize soil, preventing erosion and nutrient loss. Agroforestry improves soil structure, water retention, and nutrient cycling, contributing to long-term agricultural productivity.
3. Climate Change Mitigation: Trees sequester carbon dioxide, a major greenhouse gas, aiding in climate change mitigation. Agroforestry systems act as carbon sinks, reducing atmospheric carbon levels and mitigating global warming effects.
Economic Importance:
1. Enhanced Crop Yield and Income: Agroforestry systems provide shade, windbreaks, and improved microclimates that boost crop yields. Farmers benefit from diversified income sources through both tree products and agricultural yields.
2. Timber and Non-Timber Forest Products: Incorporating valuable tree species in agroforestry allows for sustainable timber production and non-timber forest products such as fruits, nuts, resins, and medicinal plants, enhancing economic opportunities.
3. Risk Diversification: Agroforestry minimizes risks associated with single-crop dependence. If one crop fails, other crops or tree products can still provide income, reducing vulnerability to market fluctuations.
Social Importance:
1. Livelihood Improvement: Agroforestry empowers local communities by providing employment opportunities in both agriculture and forestry sectors. It supports rural livelihoods and reduces urban migration.
2. Food Security: Diverse crops from agroforestry systems contribute to food security, as they ensure a consistent supply of various food items, even in changing climatic conditions.
3. Cultural and Traditional Values: Agroforestry often integrates traditional knowledge and practices, preserving cultural heritage and fostering a sense of identity among local communities.
Comparison of Agroforestry Practices:
To provide a comprehensive understanding, let's compare different agroforestry practices across various regions and contexts:
1. Alley Cropping: Trees are planted in rows along with crops. This practice is effective in controlling soil erosion, improving soil fertility, and providing sustainable sources of wood and fodder.
2. Silvopasture: Integrates trees and liv

The Keep Forests Healthy scorecard can help you assess how resilient your forest may be to changing climate conditions. Consider the condition of your woods and check the appropriate boxes during a woods walk in your forest. The evaluation can help you identify potential risks and highlight management options that may increase the forest's ability to cope with the pressure of changing conditions. Discuss these topics with a professional as you plan for the future of your forest.
Field visit to Kithulgala Rain forest in Sri lanaka. In the forest we were able to identify canopy layers. Also the adaptations of plants to the forest environment. Its a really nice rain forest.
Forest stands established by planting or/and seeding in the process of afforestation or reforestation. They are either of introduced species (all planted stands), or intensively managed stands of indigenous species, which meet all the following criteria: one or two species at planting, even age class, regular spacing.

The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
