A business incubator in collaboration with the community in which it operates is a "producer" of business assistance programs. The entrepreneurial ventures located in an incubator, as "consumers" of those outputs, operate in an interdependent co-production relationship with the incubator. This study explores the types of business assistance provided through co-production, the modes of co-production, and factors that affect the variability of impact. The allocation of the time of the incubator manager, the intensity of intervention, the breadth of co-production modalities deployed, and the readiness of the entrepreneur to engage in co-production are revealed as factors affecting the output elasticities related to co-production inputs.2130

Q2

How often is Aldomet (alpha methyldopa) associated with autoimmune

haemolytic anaemia or hepatitis? Is a normal person, with a positive Coombs'

test owing to previous treatment with this drug, safe to donate blood?

Q3

Q5

Q6

Patients with thalassaemia intermedia have recurrent leg ulcers and

recurrent infections. What is the mechanism of this?

Q7

What is the mechanism of iron absorption from iron polymaltose

complex and carbonyl iron?

Q8

Iron overload in patients with thalassaemia major should be checked by

measuring the serum ferritin and hepatic iron stores. How are the hepatic

iron stores measured? By liver biopsy? And does not the measurement of

serum ferritin suffice?

Q9

In the investigation for paroxysmal nocturnal haemoglobinuria (PNH),

are the sucrose haemolysis test and Ham's acid serum test commonly

done? What are the principles behind these tests?

Q10

Why isn't the blood of polycythaemia vera patients, after repeated

phlebotomies, used for transfusion purposes? Although it is a

premalignant condition, the red cells do not contain a nucleus and thus

transfusion of only pure red blood cells (RBCs) would be a great benefit.
