property of alphitobius laevegatus (black fungus bettle)

ABSTRACT
The objective of the study are to find the protein content and to
determine the antagonistic property of alphitobius laevegatus (black fungus
beetle). The Kjeldahl method for quantitative protein analysis showed that
the beetle contains 14% protein. This is comparable to the protein found in
locust (13.7), squid (14%), and pork liver (19.7%).
To test the antagonistic (dilating) property of A laevegatus, an isolated
tissue experiment using the tracheal muscle of the cat was performed.
Acetylcholine was used as the contracting agent and atropine and epinephrine
as the control antagonists (dilators). When the beetle extract was added, no
visible antagonistic effect was observed.

Feasibility study of using pineapple (Ananas comosus
Merr.) peelings as pulp for papermaking
Roelito A Begnotea, Ariel M Borja, Glenn Y Guevarra, Jansen S Lorena
ABSTRACT
The peelings was subjected to drying (preferably oven drying). The
initial weight of the samples was 1 kg. And was reduced to 600 grams after
oven drying. The samples were cooked in caustic soda or sodium hydroxide
following the soda process of pulping. The pulp was bleached using the C-E-
H process. The sheets were formed by molding the pulp in silkscreen.
The outcome of the experiment is a yellowish paper with a bursting
strength of 6.47; tearing strength of 16.89; breathing length of 3720.72;
double folds of 1.0; tensile strength of 8.5. The density was calculated to be
0.82 and the weight to be 3.70.
The paper was confirm to be an ideal material for use as Bristol and
paperboard.
