What is Sophocles suggesting to the audience about physical and metaphysical blindness in Oedipus Rex?
ipn [44]

In this context he uses the metaphor because the literary device sight is used to build Oedipus Rex and his inability to see

Explanation:

The time to reflect for Oedipus sins are given by making him blind his physical blindness gives him the time to reflect upon his mistakes done over the period of time

This refers to the knowledge that is the thing that he is unable to see he himself understands that this was the time for him to repent on his mistake and Aristotle points that the tragic of Oedipus life was due to his excessive pride and self righteous

What type and gauge of suture would be used to anastomose a synthetic aortic graft onto an aorta during an abdominal aortic aneu
ikadub [295]

Answer:

Explanation:

There are several approaches and surgical techniques in the reparation of an abdominal aortic aneurysmectomy according to the recent studies. In certain cases, it is recommended to use standard dacron graft with a flexible collar (the collar graft). The other one applies standard dacron graft.

Abdominal aortic aneurysm (AAA) is linked to 1.3% mortality in the male population older than 65-85 years. AAA is defined as the degradation of the elastic media of the previously atheromatous aortic wall. AAA occurs between the aortic hiatus in the diaphragm (T12 vertebra level) and the bifurcation into the common iliac arteries (L4 level). The diameter of the normal aorta varies in the population. In men, it is between 16 to 22 mm.

The most common risk factors for the AAA developing are smoking, male sex, older age, hypertension, hyperlipidemia and previous vascular disease.  

The most common symptoms of AAA are a pain in the abdomen, chest or lower back. The presence of peripheral vascular disease if thrombus formation is present within the aneurysm or mural emboli decrease blood flow to the periphery. In certain individuals, there is a ureteric obstruction due to the compression. The diagnosis is performed by bimanual palpation in the region above the umbilicus. Other diagnostic imaging is necessary most commonly via ultrasound and  CT scan.

Open repair is performed under general anaesthesia. The abdominal cavity is entered via a midline incision, the AAA is detected. Proximal control is provided with the clamp to the aorta (below the renal arteries). The distal control is provided via clamping the common iliac arteries. The aneurysm is opened and any thrombus removed. A graft is anastomosed to either end of the affected region of the aorta. Thus, clamps are removed and blood flow is maintained.

EVAR repair is performed by the stent-graft placement within the aneurysm which requires CT angiography preoperatively. The graft has 2 components, of which both are inserted on catheters under fluoroscopic guidance. EVAR is performed under local anaesthesia with sedation, epidural or spinal block.

The main body of the graft is inserted via the common femoral artery, while the contralateral is then inserted via the other femoral artery. In this way, there is an entirely new lumen for the distal aorta and proximal common iliac arteries.

In the case of an endovascular repair of abdominal aortic aneurysms, total percutaneous access or endovascular aortic aneurysm (EVAR) has been documented. In this approach, the most common material used may be constructed from self-expanding nickel-titanium (nitinol) with polyester graft material. The complications are defined as suture break (separation of adjacent metallic rings) and metal-ring fracture.

The most common postoperative complications are pseudoaneurysm, haematoma,  graft-enteric fistula, suture line disruption.  In case of open abdominal repair, there is always a possibility for a hernia complication and connective tissue disorder.

The presence or absence of
mestny [16]

Answer:

presence of cells

Explanation:

All living things are composed of cells. A cell can be defined as a complex biological arrangement that has all the structures and materials required for life. Cells carry out specialized functions such as, for example, metabolic functions to convert nutrients from food into energy (ATP), and reproduce by mitosis and/or meiosis. Thus, the cell is known to be the basic unit of life.

In mice, the ability to run normally is a dominant trait. Mice with this trait are called running mice (R). The recessive trait
BlackZzzverrR [31]

Answer:

Parental genotypes: RrBb, RRBB

Offspring phenotype: Running and black hair

Explanation:

Given, Running (R) is dominant over waltzing (r)

Black hair (B) is dominant over brown hair (b)

Parent 1: Heterozygous running, heterozygous black = RrBb

Parent 2: Homozygous running, homozygous black = RRBB

When they mate ( RrBb X RRBB ) :

Gametes produced by RrBb = RB, Rb, rB, rb

Gametes produced by RRBB = RB

Offspring:

        RB          Rb         rB        rb

RB   RRBB    RRBb    RrBB    RrBb

All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.

How do the heart and lungs work together​
ira [324]

Answer:

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

Explanation:

The heart and lungs work together to make sure the body has the oxygen-rich blood it needs to function properly. The Pulmonary Loop The right side of the heart picks up the oxygen-poor blood from the body and moves it to the lungs for cleaning and re-oxygenating.
