paper, they implement the trac sign recognition by using CNN, the CNN is trained by
using the dataset of 43 dierent classes of trac signs along with TensorFlow library. They
are getting results with 95% accuracy.
In the eighth paper, Paredes et al. (2020) investigate the acceptability of chrysin with the
partial replacement of pituca our based on intake of protein. They used quasi-experimental
design and food ingredients mainly wheat our, pituca our, margarine, white sugar and
yeast in their research. MINITAB and SPSS programs used by researchers for evaluation
of data and samples taken.
In the ninth paper, Nakayo et al. (2020) investigate to demonstrate the yiled of the our
of tocosh of two varieties of potato (solanum tuberosum) canchán and native variety of
“calamarca. The raw material was acquired in the district of Paucartambo province of
Pasco department of Pasco, to 2880 msnm, for the experimental study the two varieties
of potatoes were placed using as technique a pool with a water current with varied times,
where the microorganisms act and increase their activity related to the acidity.
In the tenth paper, Gutiérrez et al. (2020) discusses a great inuence on the physical security
of the urban infrastructure and the citizens of our capital city, that is why it is necessary
to apply prevention strategies since our city is located in a very vulnerable area to seismic
events, mainly huaycos, oods and landslides, settlements, landslides and other supercial
mass movements, so it is necessary to have knowledge of the causes and eects of these
phenomena, the dierent types and carrying capacity of soils in the districts of Metropolitan
Lima, in order to contribute to the knowledge of the degree of vulnerability in which urban
areas, marginal urban areas, human settlements are exposed.
In the eleventh paper, Rojas et al. (2020) identify new mechanisms that serve as tools
for the mitigation of plastic contamination through the biodegradation of low density
polyethylene using microorganisms of the species Pseudomona aeruginosa (bacteria) and
Aspergillus brazilensis (fungus) under controlled thermal conditions in an airlift bioreactor.
The methods used were 2 samples of LDPE with concentrations of 50 mg/L and 2 samples
of 100 mg/L deposited in an airlift bioreactor under controlled thermal conditions with a
duration of 7 days.
