    Reinvestigation of THOUSAND-GRAIN WEIGHT 6 grain weight genes in wheat and rice indicates a role in pollen development rather than regulation of auxin content in grains
    (Springer Science and Business Media LLC, 2021-07) ;
    OsTGW6 with other reports on IAA synthesis in cereal grains requires that this hypothesis be reinvestigated. Here, we show that TaTGW6 and OsTGW6 are members of a large gene family that has undergone major, lineage-specific gene expansion. Wheat has nine genes, and rice three genes encoding proteins with more than 80% amino acid identity with TGW6, making it difficult to envisage how a single inactive allele could have a major effect on IAA levels in grains. In our study, we show that neither TaTGW6 nor OsTGW6 is expressed in developing grains. Instead, both genes and their close homologues are exclusively expressed in pre-emergent inflorescences; TaTGW6 is expressed particularly in microspores prior to mitosis. This evidence, combined with our observation that developing wheat grains have undetectable levels of ester IAA in comparison to free IAA and do not express an IAA–glucose synthase suggests that TaTGW6 and OsTGW6 do not regulate grain size via the hydrolysis of IAA–glucose. Instead, their similarity to rice strictosidine synthase-like (OsSTRL2) suggests they play a key role in pollen development.

    Seedling-derived cotyledonary nodes and hypocotyl explants of BARI Dherosh-1 were cultured in vitro on MS medium supplemented with varying concentrations of 2, 4-Dichlorophenoxy acetic acid (2, 4-D), 6-Benzylaminopurine (BAP), Thidiazuron (TDZ), BAP with 1-Nepthaleneacetic acid (NAA), BAP with Indole 3-butyric acid (IAA) and Zeatin with IAA along with a control. Shooting response (100%) with callus was only observed from cotyledonary nodes on thidiazuron (TDZ) where hypocotyls produced only callus or callus with roots on different concentrations of plant growth regulators. Considering the shooting response, the cotyledonary nodes of BARI Dherosh-1 were cultured on various concentrations of TDZ for regeneration. The highest percentage (64.0) with maximum number (6.8) of shoots per explant were observed in 0.044 μM TDZ in 8.4 days. The regenerated shoots were rooted on ½ strength MS, MS supplemented with 2.46 μM IBA and 0.53 μM NAA. The highest percentage (83.3) and minimum days (9.7) required for root induction were recorded in 2.46 μM IBA. The rooted plantlets were transferred to soil and hardened in the plastic pots under green house conditions. The rooted shoots grew normally under natural conditions following acclimatization.

    Five eggplant cultivars were cultured on MS supplemented with 0.5 mg/l 2,4-D, resulting in the development of embryogenic calli. When the calli were subcultured onto growth regulator free MS, BARI Begun-4 produced the highest number of embryos (64) per explant followed by BARI Begun-1 (57). Later both the superior varieties in terms of embryo production were cultured on MS having 0.5, 1.0, 1.5 and 2.0 mg/l 2,4-D along with a control. BARI Begun-4 produced the highest number of embryos (67) on MS supplemented with 1.0 mg/l 2,4-D which was closely followed by BARI Begun-1 (62). Regenerated plantlets were successfully established in soil following acclimation.

    Cotyledon explants of sweetgourd (Cucurbita moschata Duch.) were cultured on MS supplemented with different concentrations of BAP alone and in combination with NAA, TDZ and 2,4-D. High shooting frequency (94.4%) was obtained from BARI Mistikumra-1 when cotyledon segments were cultured on MS with 4.44 μM BAP alone. The highest number (8.9) of shoot development and minimum days (14.7) required for shoot induction were also observed in 4.44 μM BAP treatment for BARI Mistikumra-1. In contrast, 83.3% shooting frequency were observed from BARI Mistikumra-2 producing 11.9 shoots in 8.4 days on 8.88 μM BAP. The regenerated shoots of both varieties were rooted on half strength of MS and MS supplemented with 0.53 μM NAA and 2.46 μM IBA. Rooting was observed in BARI Mistikumra-1 with 92.6% frequency in 12.3 days whereas it took 8.6 days with 93.3% rooting frequency in BARI Mistikumra-2 when shoots were cultured on MS supplemented with 0.53 μM NAA. Well-developed rooted plantlets were transferred to pots containing sterile soil and covered with polythene bags in the greenhouse for hardening. The acclimated plants were planted in the field after three weeks.

    The experiment was conducted to investigate the combined effect of different plant growth regulators and charcoal supplementation in MS medium on growth and development of plantlets regenerated from protocorm like bodies (PLBs) of hybrid orchid. The combination of BAP + NAA, BAP + IAA, BAP + IBA, and IAA + IBA at different concentrations with charcoal supplementation was studied. The result revealed that the use of different growth regulators had significant effect on different parameters studied. The maximum weight of PLBs (5.123 g) was obtained from the combination of BAP + IBA at 1.0 mg/l each. The highest shoot height (3.239 cm) and maximum number of rooted plantlets (4.473) was obtained from 1.0 mg/l each of BAP + NAA combination. The maximum number of leaves (3.490) and the maximum length of leaves (1.946 cm) were obtained from 1.0 mg/l each of BAP + IBA and the highest leaf width (1.166 cm) was obtained from 0.5 mg/l BAP +1.0 mg/l IBA combination. The highest root length was obtained from 0.5 mg/l each of BAP + IAA and the maximum number of regenerated plantlets (20) was obtained from 0.5 mg/l IAA + 1.0 mg/l IBA combination. However, the maximum fresh weight of single shoot (0.219 g) and the maximum number of roots per plantlet (6.300) was obtained from 1.0 mg/I each of IAA + IBA combination.

    Orgasmic Gushing: where does the fluid come from and how is it produced?
    (Women in Research (WiR), 2005)
    O'Brien, GM
    There are three sexual fluids from women: lubrication (e.g. transudation of fluid across the mucosa of the vagina, and mucus from the greater vestibular glands); female ejaculation (from paraurethral glands); and gushing. Orthodox western medicine and physiology does not yet have a standardized description or explanation for the third, gushing. The present paper proposes that the gushing fluid is a filtrate of plasma, produced by the mechanism known as transudation. This is an additional application for the transudation mechanism, after the well accepted roles in lubrication of the vagina, and in generating serous fluids. The present model proposes that the fluid released in a gush arises from the ventral wall of the vagina due to the presence there of increased surface area of mucosa, dilated arterioles, pressurized venous and lymphatic plexuses, and compression provided by muscle contraction during orgasm.

    Mapping Long Term Changes in Mangrove Cover and Predictions of Future Change under Different Climate Change Scenarios in the Sundarbans, Bangladesh
    (2018-05-22)
    Ghosh, Manoj Kumer
    ;
    Ground-based readings of temperature and rainfall, satellite imagery, aerial photographs, ground verification data and Digital Elevation Model (DEM) were used in this study. Ground-based meteorological information was obtained from Bangladesh Meteorological Department (BMD) for the period 1977 to 2015 and was used to determine the trends of rainfall and temperature in this thesis. Satellite images obtained from the US Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) website (www.glovis.usgs.gov) in four time periods were analysed to assess the dynamics of mangrove population at species level. Remote sensing techniques, as a solution to lack of spatial data at a relevant scale and difficulty in accessing the mangroves for field survey and also as an alternative to the traditional methods were used in monitoring of the changes in mangrove species composition, . To identify mangrove forests, a number of satellite sensors have been used, including Landsat TM/ETM/OLI, SPOT, CBERS, SIR, ASTER, and IKONOS and Quick Bird. The use of conventional medium-resolution remote sensor data (e.g., Landsat TM, ASTER, SPOT) in the identification of different mangrove species remains a challenging task. In many developing countries, the high cost of acquiring high- resolution satellite imagery excludes its routine use. The free availability of archived images enables the development of useful techniques in its use and therefor Landsat imagery were used in this study for mangrove species classification. Satellite imagery used in this study includes: Landsat Multispectral Scanner (MSS) of 57 m resolution acquired on 1st February 1977, Landsat Thematic Mapper (TM) of 28.5 m resolution acquired on 5th February 1989, Landsat Enhanced Thematic Mapper (ETM+) of 28.5 m resolution acquired on 28th February 2000 and Landsat Operational Land Imager (OLI) of 30 m resolution acquired on 4th February 2015. To study tidal channel dynamics of the study area, aerial photographs from 1974 and 2011, and a satellite image from 2017 were used. Satellite images from 1974 with good spatial resolution of the area were not available, and therefore aerial photographs of comparatively high and fine resolution were considered adequate to obtain information on tidal channel dynamics. Although high-resolution satellite imagery was available for 2011, aerial photographs were used for this study due to their effectiveness in terms of cost and also ease of comparison with the 1974 photographs. The aerial photographs were sourced from the Survey of Bangladesh (SOB). The Sentinel-2 satellite image from 2017 was downloaded from the European Space Agency (ESA) website (https://scihub.copernicus.eu/). In this research, elevation data acts as the main parameter in the determination of the sea level rise (SLR) impacts on the spatial distribution of the future mangrove species of the Bangladesh Sundarbans. High resolution elevation data is essential for this kind of research where every centimeter counts due to the low-lying characteristics of the study area. The high resolution (less than 1m vertical error) DEM data used in this study was obtained from Water Resources Planning Organization (WRPO), Bangladesh. The elevation information used to construct the DEM was originally collected by a Finnish consulting firm known as FINNMAP in 1991 for the Bangladesh government.

    Reinforced Behavioral Variability and Sequence Learning Across Species
    (Association for Behavior Analysis International (ABAI), 2012)
    Doolan, Kathleen

    Previous research shows that reinforcement of variable responding will facilitate sequence learning in rats (Neuringer, Deiss & Olson, 2000) but may interfere with sequence learning in humans (Maes & van der Goot, 2006). The present study aimed to replicate and extend previous research by assessing the role of behavioral variability in the learning of difficult target sequences across 3 species: humans (n = 60), hens (n = 18) and possums (n = 6). Participants were randomly allocated to one of three experimental conditions (Control, Variable, Any). In the Control conditions sequences were only reinforced if they were the target sequence, in the Variability conditions sequences were concurrently reinforced on a Variable Interval 60-s schedule if the just entered sequence met a variability criterion, and in the Any condition sequences were concurrently reinforced on a Variable Interval 60-s schedule for any sequence entered. The results support previous findings with animals and humans; hens and possums were more likely to learn the target sequence in the Variability condition, and human participants were more likely to learn the target sequence in the Control condition. Possible explanations for differences between the performance of humans and animals on this task will be discussed.

    A Review into Effective Classroom Management and Strategies for Student Engagement: Teacher and Student Roles in Today’s Classrooms
    (Redfame Publishing Inc, 2019-12)
    Franklin, Hayley
    ;
    A teacher's role encompasses far more than just imparting curricula outcomes to their students: they need to equip students with the necessary tools to experience social and academic success both inside the classroom and beyond it. Teachers need to empower students with the means to critically analyse the world around them in order to develop into critical independent thinkers. Students need to be proficient in utilising skills associated with higher levels of thinking, that will empower them with the ability to identify, analyse and evaluate the infinite volume of information available through our rapidly changing digital world. Just as teachers need to take responsibility for the various methods of teaching and instruction in the classroom, it is essential for students to take ownership of the learning process, to ensure future success in university environments, where sustained personal effort and metacognitive skills are fundamental to academic success. The object of the review of the literature surrounding the roles of teacher and student, effective classroom management strategies, and successful evidence-based teaching and learning pedagogies, is to assist new and experienced teachers in the promotion of a positive classroom experience for all.
