The changes of chlorophylls and main metabolites in three cultivars of Triticum
aestivum L. under the effects of osmotic and lead stresses, as well as their
interaction, were investigated. The results indicated that, the decreased Ψs and Pb concentration caused an increase in the chlorophyll content in
all plants. Conversely, the chl. a/b ratio was decreased.
Apparently, the total soluble proteins were increased in response to low ...

Introduction: Out of fifteen countries that have the
highest death rate from clinical pneumonia in children younger than
five-year-old, Ethiopia ranks as number four in the world. Regardless of this
fact, efforts to identify determinants of pneumonia have been limited in
Ethiopia. This study identifies the risk factors of pneumonia in children aged
two months to five years in urban areas of Oromia Zone, Amhara Region,
Ethiopia. Methods: The researchers used an institutional-based unmatched case
...

The article contains analysis of the interrelation
of circulation processes in the atmosphere with the change of runoff in the
basins of rivers. The results of estimates which show the relationship of circulation processes
in the atmosphere with the runoff of the zone of formation of Central Asia of
one of southern regions are discussed. The typification of circulation
processes by B.L. Dzerdzeyevskiy and previously made estimates of water
resources in the basins of rivers of South Kazakhstan we...

Background: Minimally invasive video-assisted
thyroidectomy (MIVAT) has been proposed as an alternative procedure to get the
same completeness as a conventional thyroidectomy in selected cases of differentiated
thyroid cancer. It’s considered as safe as the conventional procedure. Objective:
The purpose of the study was to do a retrospective evaluation in a series of
patients who underwent MIVAT for thyroid nodule or thyroid cancer over a two
and a half year period, in two academic centers in Co...

Acetoacetanilide derivatives 1a-c reacted with either malnonitrile or
ethyl cyanoacetate and elemental sulfur to give the thiophene derivatives 3a-f.
The reactivity of 3a towards some chemical reagents to give thiophene, theino[2,3- b]pyridine, thieno[2,3- c]pyrimidine and coumarin derivatives
was studied. The anti-tumor evaluation of the newly synthesized compounds
against the three human tumor cells lines namely breast adenocarcinoma (MCF-7),
non-small cell lung cancer (NCI-H460) a...

This essay speaks to the fact that the United States
is a consumptive society, as we are dependent on producers to provide the goods
and services necessary to maintain our daily living requirements. It addresses
a correlation between historical policies and presents events and practices
that continue to undermine public policies that benefit the consumer. Most
importantly, the role of government is to provide health and safety for the
population and protect it from a corrupt political system tha...

High self-esteem is associated with biases in
which the person overestimates their positivity, whereas low self-esteem is
associated with underestimations of one’s positivity. The current study
examined whether these biases emerge more strongly when self-regulation is
impaired. Participants first completed a task that either did or did not require
self-regulation. They later interacted with another participant and indicated
the extent to which they viewed themselves as having behaved positively ...

Four
studies tested and confirmed the hypothesis that having used self-control
reduces subsequent emotion regulation.
Participants first completed a task that either did or did not require self-
control (attention control, overriding one’s accustomed writing style, or
breaking a habit). They later encountered situations designed to activate
emotions that typically are downregulated. Participants either met someone new
(anxiety), anticipated speaking publicly (anxiety), or recalled times when the...

Background: The burden
of occupational injury in most developing countries including Ethiopia is becoming
a public health problem. Therefore, information that shows the magnitude and
predictors of occupational injury in most risky work places in Ethiopia such as
large scale metal manufacturing industries is indispensable for proper health
intervention programs.
Objectives: The aim of
this study was to assess the magnitude and factors affecting occupational
injuri ...

Heating by pipes embedded in concrete is considered in three-dimensional
space. A concrete floor resting on the ground or held at a constant temperature
has heating pipes located midway between the top and bottom of the concrete.
The top of the concrete is cooled by Newton’s law of cooling and the sides are
insulated.
