E-book The Woody Plant Seed Manual

The first comprehensive handbook on the seeds of trees and shrubs produced by the USDA Forest Service was USDA Misc. Pub. 654, Woody-Plant Seed Manual. The manuscript was ready for publication in 1941, but World War II delayed publication until 1948. The boom in tree planting in the 1950s and 1960s created a large demand for seeds and exposed the gaps in our knowledge concerning production and …

E-book Leaf Terminology

The position and complexity of plant leaves are two of the first characters to look at when identifying plants. All species of maple in the preserve have simple leaves. In addition the leaves are attached opposite to one another on the stem. The only other tree genus with opposite, simple leaves is cornus (dogwood) but that genus has entire, not lobed, leaf blades.

E-book Plant Morphology

The main function of the stem is spreading out branches bearing leaves, flowers and fruits. It conducts water, minerals and photosynthates. Some stems perform the function of storage of food, support, Protection and of vegetative propagation. The leaf is a lateral generally flattened structure borne on the stem. The leaves develop from the nodes. Their main function is photosynthesis and food m…

E-book Newton and the Netherlands How Isaac Newton was Fashioned in the Dutc…

E-book Philosophy of Developmental Biology

The history of developmental biology is interwoven with debates as to whether mechanistic explanations of development are possible or whether alternative explanatory principles or even vital forces need to be assumed. In particular, the demonstrated ability of embryonic cells to tune their developmental fate precisely to their relative position and the overall size of the embryo was once though…

E-book The State of Food and Agriculture

Agriculture is underperforming in many developing countries for a number of reasons. Among these is the fact that women lack the resources and opportunities they need to make the most productive use of their time. Women are farmers, workers and entrepreneurs, but almost everywhere they face more severe constraints than men in accessing productive resources, markets and services. This “gender …

E-book World Agriculture : Towards 2015/2030

It continues the tradition of FAO’s periodic…

E-book Flowering Plants

All flowering plants generally have four physical features in common: roots, a stem, leaves and flowers. The roots anchor the plant to the ground and collect water and minerals from the soil. The stem, which is the central part of the plant, carries the water and minerals around it and supports the leaves and flowers. The leaves absorb sunlight and carbon dioxide which the plant uses to make fo…

E-book The Basics of Soil Fertility

In cultivating the land, we live from and with soil fertility. An ecologically vital soil is continuously restoring its productivity. If we neglect its needs, it suffers as a result. The soil loses vitality, and becomes more sensitive to weather and erosion; harvests decline. In organic farming, damage cannot be offset by purely technical means. This is why an exhausted or degraded soil require…

E-book Soil Management Guide

Soils vary signifi cantly in their properties. They may be deep in some places, shallow in others, black or gray in colour, sandy or clayey in texture. Although the soil mantle covering Manitoba is far from uniform, all soils have some common factors. For example, all soil is a mixture of organic and mineral material plus water and air. While the major components remain the same, the proportion…

E-book Linear Algebra

In broad terms, vectors are things you can add and linear functions are functions of vectors that respect vector addition. The goal of this text is to teach you to organize information about vector spaces in a way that makes problems involving linear functions of many variables easy. (Or at least tractable.) To get a feel for the general idea of organizing information, of vectors, and of linea…

E-book Basic Biology : An Introduction

Earth’s most incredible feature is the presence of life. The probability of life existing is so small that it is remarkable to exist at all, yet we take it for granted every day. We are surrounded by life everywhere we turn.

The disc stars rotate around the centre of the galaxy on nearly circular orbits, with rotation speed vc ? 220 km s?1 almost independent of radius r (unlike themotion of planets in the …

E-book Mysteries of the Sun

We, in the early 21st century, know that the Sun is a star, composed mostly of hydrogen, at the center of the Solar System, and with planets orbiting around it. But ancient people didn’t have access to the same tools we have today. Their understanding about the Sun was far more concerned with the day-to-day needs of living. As such, their notions have influenced the way we (still) think of t…

E-book An Introduction to Butterly Watching

Butterfly watching is taking the country by storm! Naturalists for years have marveled at the beauty, grace and value of these wonders of nature and the increasing numbers of people now going into the field to look for butterflies demonstrates their charisma.

E-book How Modern Science Came into the World Four Civilizations, One 17th-C…

Once upon a time 'The Scientific Revolution of the 17th century' was an innovative concept that inspired a stimulating narrative of how modern science came into the world. Half a century later, what we now know as 'the master narrative' serves rather as a strait-jacket — so often events and contexts just fail to fit in. No attempt has been made so far to replace the master narrative. H. Flori…

E-book Crystallography

Crystallography is the experimental science of the arrangement of atoms in solids. The word "crystallography" derives from the Greek words crystallon = cold drop / frozen drop, with its meaning extending to all solids with some degree of transparency, and grapho = write. Unit cell is the smallest unit of volume that permits identical cells to be stacked together to fill all space. By repeating…

E-book Waves

In this chapter, we study the physics of wave motion. We concentrate on mechanical waves, which are disturbances that move through a medium such as air or water. Like simple harmonic motion studied in the preceding chapter, the energy transferred through the medium is proportional to the amplitude squared. Surface water waves in the ocean are transverse waves in which the energy of the wave tra…

E-book Wave Motion

As expected, the velocity increases when the tension increases, and decreases when the mass increases. An 80.0-m-long, 2.10-mm-diameter copper wire is stretched between two poles. A bird lands at the center point of the wire, sending a small wave pulse out in both directions. The pulses reflect at the ends and arrive back at the bird’s location 0.750 seconds after it landed. Determine the ten…

The earliest sea turtle ancestor found so far is Desmatochelys padil…

E-book Cattle Management Manual

Information about cattle instincts and associated behavior is a valuable tool that helps producers understand why cattle behave or respond as they do. Although cattle have been domesticated for a very long time, they are dictated by the herding instinct, especially if they perceive a dangerous situation. Cattle depend heavily upon sight, and they have a nearly 360-degree panoramic view. This vi…

E-book Napier Grass Management

Napier grows in low to medium altitudes. Napier grows in an altitude of up to 2000 m above sea level. However, altitudes of 2000m and above cause slow regeneration of Napier.

E-book Vanillla : Post-harvest Operations

Composition of processed vanilla beans is fairly variable and complex due to a number of variables such as species, growth conditions, soil composition, fruit maturity and mainly, the type of processing. All these variables define the relative content of the chemical constituents in the processed beans, which makes it difficult to define their typical composition. Ranadive (1994) reported a com…
