The ureterovesical junction (UVJ) is the area where the ureter—the thin tube that drains urine from your kidney—joins the bladder. When this area, or "junction," becomes blocked, a condition called ureterovesical junction obstruction develops.

Pelviureteric junction (PUJ) obstruction/stenosis, also known as ureteropelvic junction (UPJ) obstruction/stenosis , can be one of the causes of obstructive uropathy. It can be congenital or acquired with a congenital pelviureteric junction obstruction being one of the commonest causes of antenatal hydronephrosis. Epidemiology

A Geometric View of Vectors A vector is a specific quantity drawn as a line segment with an arrowhead at one end. It has an initial point, where it begins, and a terminal point, where it ends. A vector is defined by its magnitude, or the length of the line, and its direction, indicated by an arrowhead at the terminal point.

With this theorem for double integrals, we can change the variables from (x, y) to (u, v) in a double integral simply by replacing. dA = dxdy = |∂(x, y) ∂(u, v)|dudv. when we use the substitutions x = g(u, v) and y = h(u, v) and then change the limits of integration accordingly.

The Dot and Cross Product. The Dot Product. Definition. We define the dot product of two vectors. v = a i + b j and w = c i + d j. to be. v . w = ac + bd. Notice that the dot product of two vectors is a number and not a vector. For 3 dimensional vectors, we define the dot product similarly:

The dot product is a multiplication of two vectors that results in a scalar. In this section, we introduce a product of two vectors that generates a third vector orthogonal to the first two. Consider how we might find such a vector. Let u = 〈u1, u2, u3〉 and v = 〈v1, v2, v3〉 be nonzero vectors.

Solution: 2.6 Condition for three vectors a, b, and c to be coplanar is 2.7 From the definition for Kronecker delta: δij = 0 if i 6 = j and δij = 1 if i = j (5) Thus δij δij = δiiδii = 1 + 1 + 1 = 3 (6)

Figure 16.6.6: The simplest parameterization of the graph of a function is ⇀ r(x, y) = x, y, f(x, y) . Let's now generalize the notions of smoothness and regularity to a parametric surface. Recall that curve parameterization ⇀ r(t), a ≤ t ≤ b is regular (or smooth) if ⇀ r ′ (t) ≠ ⇀ 0 for all t in [a, b].

Put enough of these curves together and they form a surface. Example 16.6.1 16.6. 1: Consider the function r(u, v) = v cos u, v sin u, v r ( u, v) = v cos u, v sin u, v . For a fixed value of v v, as u u varies from 0 to 2π 2 π, this traces a circle of radius v v at height v v above the x x - y y plane.

For instance, if you suppose that u u and v v are already orthogonal, your choice of x x is simply any multiple of u u, because. (u − λu) ⋅ v = (1 − λ)(u ⋅ v) = 0. ( u − λ u) ⋅ v = ( 1 − λ) ( u ⋅ v) = 0. What you would want to do is the exact same thing, but suppose further more that x x is co-linear to v v, hence x = λv x.
