El documento habla sobre el uso de la tecnología y las rutinas de pensamiento en la educación. Menciona que la tecnología puede usarse como una herramienta innovadora para buscar información y crear presentaciones que hagan el aprendizaje más constructivo para los estudiantes. También describe algunas rutinas de pensamiento como "Yo pensaba, ahora pienso" y "Tiempo en silencio para pensar" que pueden estimular el pensamiento crítico y creativo de los estudiantes. Además, resalta la importancia de que los docentes estén

Alterations in Fatty Acid Profile of Polar Lipids Accompanied By Growth and S...iosrjce
Polar lipids are essential membrane components of plant cells. They are known to affect certain
membrane properties like permeability, fluidity and active transport. In the present study, individual leaf buds
were tagged on the day of appearance and sampling began 7 days later. Additional samples were taken at 7
days intervals until leaf abscission occurred about 77 days after tagging. The experiments were performed from
August to November, a time period characterized by a day length of 12 ± 2.0 h and average day and night
temperature of approximately 30 and 20°C, respectively. The fatty acid composition of polar lipids from young,
mature and senescent leaves of Rauwolfia serpentina was studied in the present study. Green leaves were
observed to contain a considerable amount of hexadecatrienoic acid (16:3) in monogalactosyldiglyceride
(MGDG), suggesting R. serpentina to be member of 16:3 plants’ family. The percentage of linolenic acid (18:3)
in the chloroplast lipids was lower in senescent leaves than that of green tissues. Senescent leaves also had
lower proportions of MGDG 16:3 and phosphatidyl glycerol (PG) hexadecanoic acid (16:1). Such selective
catabolism of molecular species of these lipids may be suggestive of significant alterations in ultra structure of
chloroplast membranes, thus probably affecting the accumulation of indole alkaloids in the leaf tissue. Besides,
the age dependent alterations in the fatty acid composition of other polar lipids, namely, phosphatidyl choline
(PC), phosphatidyl inositol (PI), phosphatidyl ethanolamine (PE), and phosphatidyl serine (PS) indicate the
possibility of degradation of the organelles other than chloroplast (principally vacuoles) in the leaf cells

Bioprocess development for enhanced spore production in shake flask and pilot...iosrjce
Bacillus thuringiensis subsp. Israelensis (Bti), has proven to be a safe and effective larvicide for controlling
mosquito and black fly larvae. The effect of cultivation and bioprocess development on Bti growth and sporulation was
investigated in shake flask level and batch cultivation in the semi-industrial scale 16-L stirred tank bioreactor. For
industrial production of biocontrol microorganism, it is necessary to obtain high cell mass and spore production in a short
time with low cost cultivation media. In this study, the new composition of production media was optimized which composed
of (g L
-1
): glucose, 10; yeast extract, 30; KH2PO4, 5; K2HPO4, 5; MgSO4. 7H20, 0.005; MnSO4.H2O, 0.03; FeSO4, 0.01;
CaCl2.7 H2O, 0.05; NaH2PO4, 1.5; NH4H2PO4, 1.5. The maximal cell dry mass and spore production, Sporemax for shake
flask study were 4.26 gL-1
at 36 h and 3.29106
spore mL-1
, respectively. Furthermore, studies of the cultivation conditions
under controlled and uncontrolled pH in the 16L-bioreactor was performed. The growth of Bti under uncontrolled pH
cultivation showing decreased of glucose and total protein concentration in the media was correlated with the vegetative cell
growth and sporulation. The maximal cell dry mass and Sporemax for uncontrolled pH bioreactor were 4.14 gL-1
at 36h and
3.7106
spore mL-1
, respectively. The maximal cell dry mass and spore production, Sporemax for controlled pH bioreactor
were 3.36 gL-1
at 26 h and 3.23 106
spore mL-1
, respectively. In conclusion, batch cultivation in 16-L bioreactor with the
new optimized production medium under uncontrolled pH condition increased of the cell dry mass and number of spores up to 23 % and 47 % , respectively
Qualitative Evaluation and Hydrogeochemical Attributes of Groundwater in Ower...iosrjce
The qualitative evaluation and hydrogeochemical attributes of groundwater in Owerri Capital
Territory Owerri was investigated to assess the quality for human consumption and agricultural purposes. A
total of sixteen (16) groundwater samples were collected and analyzed for physicochemical and biological
properties. The range of temperature (oC), colour (Hz), and turbidity of groundwater in the study area are
between: 20-28.3, 5-15, and 1-50 respectively. The average of pH , conductivity (us/cm),TDS (mg/l), and
hardness (mg/l) are: 7.66, 0.135, 34.64, and 7.94 respectively. The result also reveals that the concentration of
Na+
(mg/l), K+
(mg/l), Ca2+(mg/l), Mg2+(mg/l), Fe+
(mg/l), Pb2+(mg/l),Cd2+(mg/l), Cu+
(mg/l),and Zn2+ (mg/l)
range between: 3.33-7.6, 0.2-6.8, 2.4-8.3,1.02-3.44, 0.001-0.59, 0.001-0.01, 0-0.16, 0.06-2.88 and 0.01-2.18
respectively. Water Classification result of the groundwater samples show the predominance of alkali
bicarbonate water type (Na+ + K+
) - HCO3
-
that is largely soft and therefore, mostly of acceptable quality for
household uses. Sodium Absorption Ratio (SAR) of the groundwater samples in the study area showed that the
samples fall below 1.4meq/l, indicating predominance of excellent water for irrigation purposes in accordance
with recommended standard. This study recommends among other things that groundwater resources
development in the area requires elaborate qualitative assessment, to ensure that any necessary pre-use
treatment is effected.
2. Tecnología y Educación
la tecnología se ha vuelto una herramienta
innovadora en los centros educativos.
Esta herramienta nos sirve para buscar
información, crear nuestras propias
presentaciones para que el aprendizaje sea
constructivo para los estudiantes, podemos
usar YouTube para buscar videos sobre los
contenido que veremos en nuestras aula.
Si se ve el tema de la conquista podemos
buscar videos así el aprendizaje no se vuelve
tedioso.
4. Pensamiento critico
Podemos definir como
pensamiento critico en un
persona al poder tomar
decisiones propias, tener
su propio punto de vista
sin faltar el respeto al
otro, tener compresión de
lo que leen, hacen.
6. Herramientas
Las podemos utilizar como
material didáctico para hacer
resúmenes, mapas conceptuales,
presentaciones; entre otras.
Estas herramientas actualmente
son muy importante tanto en la
educación como en lo laboral e
incluso en la cotidianidad de las

ahora pienso”
Es un tipo de rutina en la que
podemos nuestro pensamiento
se va a ir modificando
conforme vamos teniendo
conocimiento de diversos
temas que son estudiados en
las aulas de los centros
educativos
9. “Tiempo en silencio
para pensar”.
Nuestros alumnos deben
entender la importancia del
silencio en distintos momentos
en nuestras aulas.
Para poder pensar, leer;
debemos estar concentrados
sin que los ruidos exteriores
nos desconcentren.
10. Rutinas del
pensamiento y
pensamiento visible
Las rutinas del
pensamiento son muy
útiles para que podamos
ver el pensamiento que
hay detrás de cada niño
por medio de estrategias
11. Habilidades del
siglo XXI
Los docentes deben estar
actualizados; es decir los
docentes en la actualidad deben
tener conocimiento de las
aplicaciones que tiene la
tecnología para poder
implementarlas en los
estudiantes y además que son
útiles
12. Centros educativos del
siglo XXI
En la mayoría de los centros
educativos cada vez se ve como la
tecnología esta dentro de estas
instituciones.
Podemos lograr un aprendizaje
constructivo y cooperativo por
medio de videos, presentaciones
