Background and Objective: The mola carplet, Amblypharyngodon mola is a representative small indigenous fish species that is enriched with different vitamins and minerals. The main objective of this study was to determine the reproductive biology of A. mola for better scientific management and conservation in hapa based culture, set up in a large earthen pond. Materials and Methods: The experiment was conducted of three treatment with two replicates along hapa size varied treatment: T1 (2 m3), treatment: T2 (10 m3) and treatment: T3 (20 m3) with two replicates each and the stocking density in those hapas were 50, 250 and 500g, respectively in April, 2012 to March, 2013. Some biological characteristics, gonad weight, Gonadosomatic Index (GSI) and condition factor (K) of both sexes were observed. Results: Cycle of gonadal maturation and month-wise variations were documented with their fecundity, size-frequency of intra-ovarian oocytes in females. Throughout the suitable physic-chemical parameters, monthly microscopic examination of gonad revealed five maturity stages of female A. mola but male showed same four stages. Ripe ova have been observed for nine consecutive months (April to December) which referring extended the breeding season. Considering the stocking density and hapa sizes, A. mola bred the highest frequency in T3 during the culture period. Different size classes of intraovarian oocytes have portrayed the batch-wise (asynchronous) development of oocytes in A. mola throughout the culture period. Conclusion: This evidence suggests that A. mola has its inherent regulating mechanism of oocyte development adapted to the annual life of the fish, in spite of their single spawning habit, they discharge all oocytes in different batches throughout the spawning season. |

Many developing countries are looking at means and ways to implement inclusive education,
although, most do not seem to understand on the way to handle different learning abilities of individuals.
Normal children with average learning capabilities may be generalized to a common learning experience but
individuals with Learning Disabilities (LD) cannot cope with the learning capabilities of the normal children. It
is thus, important to introduce personalized learning for individual such that students with different LD can
effectively learn at their own pace, although, in an inclusive environment. Thus, this study takes the
opportunity to understand the brain functionality and to allow student to be profiled for differentiated learning
experience. The availability of Electroencephalogram (EEG) devices and its ability to measure and capture brain
waves for analysis makes it easier for researchers to use them in understanding the functionality and state of
the brain. The mobility and low-cost EEG devices, recently, makes it attractive for researchers and teachers in
the long run to provide profiling of every students. In general, this can help students to self-pace their learning
experience. Moreover, various engineering tools and method were also introduced to improve the performance
of the detection system for early childhood developmental disorder. In this research, 10 students with Autism
Spectrum Disorder (ASD) and normal children were measured for brain wave pattern differences through, the
use of EEG in detecting ASD. An extended application of the EEG processing using the neurophysiological
interface of affect were also, used to understand behavior through personality traits providing
new avenue and possibilities of profiling students effectively. |

Haloxylon recurvum Bunge ex Boiss (Chenopodiaceae) is distributed chiefly from the Mediterranean region to Central and South Asia and traditionally applied externally for a variety of disorders. We investigated the in vivo toxic potential of crude methanolic extract of the whole plant and its n-hexane, chloroform, butanol, ethylacetate and aqueous soluble fractions by determining their acute toxicity and acute neurotoxicity in mice using Lorke`s method and inverted screen test. In vitro studies were also conducted in order to investigate its antilipoxygenase, antibacterial and antifungal activities. All the fractions showed a narrow margin of safety in mice, except the aqueous fraction, which did not produce any mortality even at the highest tested dose (5000 mg kg-1). At non-lethal doses, only the aqueous fraction (TD50 1264 mg kg-1) was found to produce neurotoxicity in mice. In in vitro lipoxygenase inhibition assay, the ethylacetate fraction showed the most significant inhibitory activity. Crude methanolic extract and its butanol soluble fraction showed the most potent antifungal and antibacterial activity for all the materials tested. Thus, this report verifies the traditionally reported toxicity of this plant, as the majority of its components have exhibited a narrow margin of safety, however, they have been found active in in vitro studies, therefore, further studies are required in order to isolate the most active toxic compounds and differentiate them from these fractions.

Culture refers to the cumulative knowledge, beliefs, values and concepts that are accepted by a group of people. Such information are shared and inherited from the previous generations in order for one to be blended and accepted in a society. Different cultural groups communicate differently that is distinct and unique making homogeneous interpretation of underlying emotional contents are more accurate. However, universality of cultural-influenced speech can be observed when cross cultural speeches are being interacted from different cultural groups to one another especially with the advancement of communication technology. In this study, two different cultural-influenced speech datasets representing American (NTU-American) and European (Netherland EmoSpeech) are employed to investigate their similarity and dissimilarity in term of heterogeneous listener’s perception on the underlying emotional contents. The Mel Frequency Cepstral Coefficient (MFCC) feature extraction method and Multi Layer Perceptron (MLP) classifier are coupled to determine four different emotions, namely; anger, happiness, sadness and neutral acting as emotionless state. From the experimental result, it is noted that the proposed approach yielded accuracy performance of two times better than chance guessing. Moreover, the Netherland EmoSpeech dataset managed to obtain comparative accuracy with the established NTU-American dataset demonstrating that the data is satisfactory for speech emotion recognition purposes. |
