Influence of cultural ethos on portfolio writing: reflection among faculty and students
As times are changed, the change is fett in teaching-learning process too.
Those days class rooms were teacher-centered. Students were at the receiving end. And
they were expected to reproduce what they have received. Learning hardly had real life
situations. They were content based and compartmentalized. But today's classrooms
expect interactions, questioning, responding and reflecting on both sides. There is
synergy of thoughts, ideas and intellectual expertise. Ultimately, today's teachers lend
their hands towards bringing up productive citizens.
A portfolio is a portable, systematic, purposeful collection of work, selected to
provide information about attitude, level of development and growth during a given
period of time. It is a powerful visual tool that provided evidence of personal
reflections, learning growth and development and a comprehensive and complex
overview of skills.
The success of a learner lies on goal orientation. The goal oriented individual
has to have a watch over on his progress. Portfolios provide students with the
opportunity to see how they have progressed as learners. Students begin to reflect on
their strengths as a learner, areas where they need to improve, what constitutes quality
work and how their work reflects the expected standards. Here portfolio is a tool for
self-monitoring and self-evaluation and it is useful as a 'marketing tool' in the job
search process.
Today's classroom environment reflects the cultural ethos. The tone and the
style of the message the teacher carries to his class, his expertise in the Meld, and
integrity reflect in the success of his teaching. He has to have teaching goals, teaching
philosophy and design for learner's portfolio. Maintaining portfolio writing both on the
part of teacher as well as the learner develop healthy learning culture towards social
development It results in development of human resources for economic development

Localization of the Epileptogenic Foci in Tuberous Sclerosis Complex: A Pediatric Case Report
Tuberous sclerosis complex (TSC) is a rare disorder of tissue growth and differentiation, characterized by benign hamartomas in the brain and other organs. Up to 90% of TSC patients develop epilepsy and 50% become medically intractable requiring resective surgery. The surgical outcome of TSC patients depends on the accurate identification of the epileptogenic zone consisting of tubers and the surrounding epileptogenic tissue. There is conflicting evidence whether the epileptogenic zone is in the tuber itself or in abnormally developed surrounding cortex. Here, we report the localization of the epileptiform activity among the many cortical tubers in a 4-year-old patient with TSC-related refractory epilepsy undergoing magnetoencephalography (MEG), electroencephalography (EEG), and diffusion tensor imaging (DTI). For MEG, we used a prototype system that offers higher spatial resolution and sensitivity compared to the conventional adult systems. The generators of interictal activity were localized using both EEG and MEG with equivalent current dipole (ECD) and minimum norm estimation (MNE) methods according to the current clinical standards. For DTI, we calculated four diffusion scalar parameters for the fibers passing through four ROIs defined: (i) at a large cortical tuber identified at the right quadrant, (ii) at the normal appearing tissue contralateral to the tuber, (iii) at the cluster formed by ECDs fitted at the peak of interictal spikes, and (iv) at the normal appearing tissue contralateral to the cluster. ECDs were consistently clustered at the vicinity of the large calcified cortical tuber. MNE and ECDs indicated epileptiform activity in the same areas. DTI analysis showed differences between the scalar values of the tracks passing through the tuber and the ECD cluster. In this illustrative case, we provide evidence from different neuroimaging modalities, which support the view that epileptiform activity may derive from abnormally developed tissue surrounding the tuber rather than the tuber itself

Influence of fibre length and denier on properties of polyester ring and air-jet spun yarns
163-168The
effect of polyester fibre length and denier on hairiness, abrasion resistance,
flexural rigidity, co-efficient of friction and compressional energy of air-jet
and ring-spun yarns has been studied. It is observed that the yarn hand in
terms of flexural rigidity and compressional energy improves by using finer
fibres in air-jet yarns. Increase in fibre length decreases
the
yarn hairiness, abrasion damage and yarn-to-metal friction in both air-jet and
ring yarns. Finer fibres decrease the hairiness and abrasion damage and
increase the yarn-to-metal friction in both air-jet and ring yarns

Yarn quality improvement with an air-jet attachment in cone winding
289-294An
air-jet nozzle for cone winding machine was designed and fabricated to decrease
the hairiness of yarn and, thereby, to control the deterioration in yarn
quality. Yarn quality improvement in five different counts (two carded and
three combed) was studied using air- jet nozzles of three different orifice
angles (30°, 45° and 60°) and three different air pressures
(0.5
kg/cm2, 1.0 kg/cm2 and 1.5 kg/cm2). It has
been observed that the best results are achieved with air-jet nozzle of 60°
orifice angle and 1.0 kg/cm2 air pressure. Using this nozzle during
winding, the hairs in ring yarn decrease by 50-75%. Hence, the use of air-jet
nozzle in cone winder helps to maintain the quality of wound yarns at par with
that of ring yarns

effect of spindle speed on yarn quality and end breakage rate while using lower
package size has been studied. It is possible to increase the spindle speed
even by 20% in the case of 40s and finer counts while using lower package size
which would offer a saving of Rs. 140/spindle/year. Yarn quality attributes
like strength, evenness and thick places are not affected at higher spindle
speeds whereas thin places, hairiness and CV of strength show a tendency to
increase with spindle speed.</span
Influence of rotor speed in open-end spinning on yarn quality

been investigated for 6 different mixings made out of natural/man-made fibres.
Above 40,000 rpm, polyester tends to become weaker whereas cotton, viscose and
polyester blends remain unaffected up to 55,000 rpm. Evenness and imperfections
deteriorate for all the fibre types as rotor speed increases. Explanations
based on theoretical considerations have been offered for the observed
phenomena.</span

have been found 30-35% weaker than their ring counterparts. While the evenness
is better for MMF rotor-spun yarns, the various imperfection sare also less in
MMF yarns by 15-20%.</span
Influence of wire point density in cards and combers on neps in sliver and yarn quality
9-15Card
slivers were produced from two Indian cottons of micronaire values 2.7 and 3.1
in a 4th generation card using flat tops of five different wire
point densities and spun into 80s and 100s combed yarns. Card sliver neps as
well as imperfections in the corresponding yarn samples produced using those
slivers were estimated. Conducting trials were also carried out using cylinder
wires, flat tops and combing segments of variable density. Cylinder wires of
variable density in card reduce sliver and yarn nep content by about 35%.
Combing segments with 4 partitions in comber produce slivers and yarns with
about 25% lower neps as compared to combing segments of 2 partitions.
