Kemajuan terkini dalam teknologi pendidikan telah menunjukkan potensi dalam menyokong keperluan pembelajaran unik bagi Murid Berkeperluan Pendidikan Khas (MBPK). Namun, terdapat isu permasalahan bagaimana integrasi teknologi ini dapat memberikan manfaat yang sama kepada semua murid dalam kumpulan yang pelbagai ini khususnya pendidikan khas. Dalam landskap pendidikan hari ini, integrasi alat dan bahan yang disokong teknologi untuk MBPK menjadi semakin penting, walaupun keberkesanannya boleh berbeza dengan ketara berdasarkan keperluan individu dan konteks pembelajaran. Objektif kajian ini adalah untuk menilai keberkesanan platform pembelajaran interaktif I-Zoo terhadap keupayaan kognitif MBPK yang mengalami masalah pendengaran, dengan fokus khusus pada kemahiran pengecaman, pengisyaratan dan ejaan. Metadologi kajian ini menggunakan pendekatan kuantitatif melalui kajian tindakan dan melibatkan reka bentuk pra-dan pasca untuk menilai kesan I-Zoo terhadap kemahiran kognitif serta menggunakan analisis deskriptif. Dapatan kajian menunjukkan berlaku peningkatan markah yang ketara, dengan peningkatan 44% dalam skor yang diperhatikan selepas intervensi. Ini menunjukkan bahawa alat pembelajaran interaktif seperti I-Zoo berpotensi meningkatkan keupayaan kognitif tertentu dalam kalangan MBPK. Walau bagaimanapun, tahap peningkatan yang berbeza-beza menekankan keperluan untuk penyesuaian lanjut dan adaptasi alat ini bagi memenuhi keperluan pembelajaran individu dengan lebih baik. Kajian lanjutan perlu meneroka kesan jangka panjang teknologi ini dan integrasinya ke dalam kerangka kerja pembelajaran yang lebih luas untuk memaksimumkan manfaatnya kepada semua MBPK.

Genetic relationship, antibiotic resistance pattern and virulence factors of Klebsiella pneunoniae strains isolated from meningitis patients
Authors: Rustampoor Mohammad Hussain , Beigverdi Reza , Shafaq Najibullah 
Published: October 2024

Backgroud: Meningitis due to Klebsiella pneunoniae is increasingly reported from several Asian countries. Microbiological characteristic of K. pneumoniae strains causing meningitis is not yet explored in Iran. The aim of this study was to demonstrate antibiotic resistance pattern and virulence factors, as well as the genetic relationship of K. pneumoniae strains isolated from meningitis patients. Materials and Mehtods: Eight K. pneumoniae isolates were collected from hospitalized patients at Imam Khomeini hospital, Tehran-Iran from 14 May 2018 to 15 Mar 2020. The antibiotic resistance pattern was determined by disc diffusion method. Antibiotic resistance genes and virulence-associated genes were traced by Polymerase Chain Reaction. Repetitive Extragenic Palindromic Polymerase Chain Reaction was used for evaluation of the genetic relationships among isolates. Findings: Six out of eight isolates were resistant to almost all the 15 antibiotics tested. These six isolates harbored triple antibiotic resistance genes: blaOXA-48, blaSHV, and aac (6’)-Ib. Five of these isolates co-harbored aac (3)-IIa gene. Besides, blaTEM and blaCTXM-1 were detected in five and three isolates respectively. blaNDM-1 was identified in one isolate. All isolates harbored acrAB, ompK36, and tolC resistance genes. None of the isolates were related to K1 or K2 capsular serotypes. The most commonly detected virulence genes were entB (100%), mrkD (100%), ybtS (62.5%) and kfu (25%). rep-PCR fingerprinting discriminated seven isolates into three clusters. Conclusion: Simulations presence of the genes coding for Extended Spectrum Beta Lactamases, Carbapenemases, and Aminoglycoside Modifying Enzymes narrows therapeutic alternatives and imposes a heavy load on the public health system. Antibiotic susceptibility test is recommended however, Carbapenems can still be considered as first-line medications for preliminary empirical treatment of K. pneumoniae meningitis before obtaining susceptibility test results. Low genetic diversity suggests the circulation of certain K. pneumoniae clones in hospital which highlights the establishing of effective infection observation and prevention program.
The 1930 Mawbanna Thylacine: The evidence and photographic legacy of the last confirmed wild kill
Authors: Linnard Gareth , Sleightholme Stephen R. 
Published: October 2024

ABSTRACT
The last confirmed wild Thylacine kill, that of an adult male, was made by Wilfred Batty on a property leased by his father in the Parish of Anderson, within the Mawbanna district on the north-west coast of Tasmania, at midday on the 13th of May 1930. In terms of the historical traceability of the species in the wild, the shooting of the Mawbanna Thylacine, the first of only four evidentially supported specimens recovered during the 1930s, antedates the capture of the two Delphin juveniles by 55 and 83-89 days respectively, the male of which being the only credible candidate for the last captive Thylacine (Linnard et al., 2020; Linnard & Sleightholme, 2023). It also predates the 1931 Kaine capture (Sleightholme et al., 2020), the final evidentially supported occasion when a Thylacine was retrieved from the wild by approximately nine months. A contemporary newspaper article provided a brief account of the kill with the incident becoming synonymous with the trophy image of Batty posed with the dead Thylacine. However, before his death in 1989 Batty's testimony was recorded by three detailed sources - McIntyre (1955), Thompson (1974) and Ryghe (1990), allowing a more nuanced understanding of the circumstances surrounding the kill. Additionally, this publication introduces three previously unseen photographs, allowing all the known images of the kill to be sequenced, attributed, and their context discussed.

In varietal selection field trials, spatial variation and genotype by environment (GxE) interaction are frequent and present a major challenge to plant breeders comparing the genetic potential of several cultivars. To consistently select superior cultivars that increase agricultural production, bread wheat breeding studies must be evaluated using efficient statistical techniques. By modeling the interactions of geographical field trends and genotypes by environment interaction, this work aimed to forecast the genetic potential of bread wheat varieties across settings and improve selection tactics. The dataset utilized in this investigation consisted of sixteen multi-environment trials (MET) that were carried out using a randomized complete block design (RCBD), with two replications arranged in plot arrays of rows and columns. The findings showed that the factor analytical and spatial models were effective ways to analyze the data for this study under the linear mixed model. By ranking average Best Linear Unbiased Predictions (BLUPs) within clusters, the 16 bread wheat environments were grouped into three mega environments (C1, C2, and C3) based on yield. This served as a selection indicator. Ranking average BLUPs helped in the selection of superior and stable genotypes. The first cluster (C1)'s mean BLUP values were used to score the genotypes' performance; C2 and C3 were excluded because of their limited genetic variety and low genetic connection with the other trials. The genotypes with the highest potential based on this cluster were EBW192346 and EBW192347, chosen for a subsequent verification study to release a variety. The estimates for variance component parameters ranged from 0.013 to 3.024 for genetic variance and from 0.072 to 0.37 for error variance. Hence, scaling up the use of this efficient analysis method will improve the selection of superior bread wheat varieties.

Published: October 2024

Aims: The study aimed to evaluate the different growing media & polybag size for seedling growth of rough lemon rootstock.
Study Design: The experiment used a Complete Randomized Design (CRD) with three replications.
Place and Duration of Study: The study "Effect of Growing Media and Polybag Size on Rough Lemon Seedling Growth" took place in an insect-proof net house at CCS Haryana Agricultural University during the 2021-2022 academic year.
Methodology: It comprising of 30 treatment combination i.e., ten different growing media: T1: garden soil; T2: soil: sand (1:1); T3: soil: sand: leafmold (1:1:1); T4: soil: cocopeat (1:1); T5: sand: cocopeat (1:1); T6: soil: sand: cocopeat (1:1:1); T7: soil: FYM (1:1); T8: sand: FYM (1:1); T9: soil: sand: FYM (1:1:1); T10: soil: sand: FYM: cocopeat (1:1:1:1), and the polybags S1: large (30 x 18 cm), S2: medium (21 x 18 cm) & S3: small size (17 x 16 cm) bags.
Results: The study found that adding cocopeat to growing media (T4, T5, T6) resulted in earlier germination and higher rates (87-89%) Whereas, T4 to T10 media consists of either FYM, cocopeat for both resulted into more germination 87-89% as compared to controls (T1, T2, T3). The most of the root growth parameters i.e., diameter of tap root(2.45mm), fresh root weight (4.63g) & dry root weight (1.21g) & root: shoot ratio (0.61) improved with the media sand: FYM, soil: FYM, sand: soil: FYM, sand: soil: FYM: cocopeat in equal proportion. However, when media supplemented with cocopeat (T4, T5 & T6 ) also showed appreciable results as compared to soil, sand: soil & soil: sand: leafmold. However, sand: FYM, sand: cocopeat treatments were best in respect of number of primary roots (61.22), root volume (6.44ml). Whereas, sand: soil showed very poor results in all growth aspects. Among polybags sizes, large size (30 x 18cm) bags performed best in most of the germination & root growth parameters.
Conclusion: Media enriched with organic matter outperformed sole media across all parameters, while larger polybags produced significantly better results than medium and small sizes.
Removal of deep lithosphere in ancient continental collisional orogens: A case study from central Tibet, China
Authors: Chen Sheng‐Sheng , Fan Wei‐Ming , Shi Ren‐Deng , Gong Xiao‐Han , Wu Kang 
Published: March 2017

AbstractWidespread but small‐volume Late Cretaceous volcanic rocks in central Tibet contain important information on the Lhasa‐Qiangtang collision process. In this contribution, we focus on Late Cretaceous volcanics in the southern Qiangtang subterrane and present zircon LA‐ICP‐MS U‐Pb ages, whole‐rock major and trace element compositions, and Sr‐Nd isotopic data. Zircon LA‐ICP‐MS U‐Pb dating yielded a concordant age of 80 Ma, which postdates the Early Cretaceous collision of the Qiangtang and Lhasa terranes. The volcanic rocks are potassium‐rich alkaline andesites with high contents of K2O (3.45–5.11 wt %) and Th (13.39–25.02 ppm), as well as high K2O/Na2O ratios (0.6–0.9). They have higher REE and HFSE contents than coeval Mg‐rich and adakite‐like magmatic rocks that can be related to partial melting of a thickened lower crust. Moreover, they have higher values of Mg# and lower contents of SiO2 than lower continental crust‐derived rocks in central Tibet and experimental data of mafic rocks. We argue that the andesites were generated after the removal of thickened lithospheric mantle and subsequent to the final Lhasa‐Qiangtang amalgamation in a postcollisional setting. The high‐K characteristics can be explained by producing the primitive andesite magmas from partial melting of the residual and shallow metasomatized lithospheric mantle (the K‐rich layer) during heating by upwelling asthenosphere; subsequently, these primitive andesite magmas were subjected to fractional crystallization to generate the Amdo andesites. The way in which these andesites were formed provides evidence for the lithospheric thickening and uplifting of central Tibet during the Late Cretaceous prior to India‐Asia collision.
Revisiting ENSO/Indian Ocean Dipole phase relationships

Published: March 2017

AbstractHere we show that the characteristics of the Indian Ocean Dipole (IOD), such as its power spectrum and phase relationship with the El Niño–Southern Oscillation (ENSO), can be succinctly explained by ENSO combination mode (C‐mode) wind and heat flux forcing together with a seasonal modulation of the air/sea coupled Indian Ocean (IO) Bjerknes feedback. This model explains the observed high‐frequency near‐annual IOD variability in terms of deterministic ENSO/annual cycle interactions. ENSO‐independent IOD events can be understood as a seasonally modulated ocean response to white noise atmospheric forcing. Under this new physical null hypothesis framework, IOD predictability is determined by both ENSO predictability and the ENSO signal‐to‐noise ratio. We further emphasize that lead/lag correlations between different climate variables are easily misinterpreted when not accounting properly for the seasonal modulation of the underlying climate phenomena.
A model for tidewater glacier undercutting by submarine melting
Authors: Slater D. A. , Nienow P. W. , Goldberg D. N. , Cowton T. R. , Sole A. J. 
Published: March 2017

AbstractDynamic change at the marine‐terminating margins of the Greenland Ice Sheet may be initiated by the ocean, particularly where subglacial runoff drives vigorous ice‐marginal plumes and rapid submarine melting. Here we model submarine melt‐driven undercutting of tidewater glacier termini, simulating a process which is key to understanding ice‐ocean coupling. Where runoff emerges from broad subglacial channels we find that undercutting has only a weak impact on local submarine melt rate but increases total ablation by submarine melting due to the larger submerged ice surface area. Thus, the impact of melting is determined not only by the melt rate magnitude but also by the slope of the ice‐ocean interface. We suggest that the most severe undercutting occurs at the maximum height in the fjord reached by the plume, likely promoting calving of ice above. It remains unclear, however, whether undercutting proceeds sufficiently rapidly to influence calving at Greenland's fastest‐flowing glaciers.
A probabilistic approach to quantifying hydrologic thresholds regulating migration of adult Atlantic salmon into spawning streams
Authors: Lazzaro G. , Soulsby C. , Tetzlaff D. , Botter G. 
Published: March 2017

AbstractAtlantic salmon is an economically and ecologically important fish species, whose survival is dependent on successful spawning in headwater rivers. Streamflow dynamics often have a strong control on spawning because fish require sufficiently high discharges to move upriver and enter spawning streams. However, these streamflow effects are modulated by biological factors such as the number and the timing of returning fish in relation to the annual spawning window in the fall/winter. In this paper, we develop and apply a novel probabilistic approach to quantify these interactions using a parsimonious outflux‐influx model linking the number of female salmon emigrating (i.e., outflux) and returning (i.e., influx) to a spawning stream in Scotland. The model explicitly accounts for the interannual variability of the hydrologic regime and the hydrological connectivity of spawning streams to main rivers. Model results are evaluated against a detailed long‐term (40 years) hydroecological data set that includes annual fluxes of salmon, allowing us to explicitly assess the role of discharge variability. The satisfactory model results show quantitatively that hydrologic variability contributes to the observed dynamics of salmon returns, with a good correlation between the positive (negative) peaks in the immigration data set and the exceedance (nonexceedance) probability of a threshold flow (0.3 m3/s). Importantly, model performance deteriorates when the interannual variability of flow regime is disregarded. The analysis suggests that flow thresholds and hydrological connectivity for spawning return represent a quantifiable and predictable feature of salmon rivers, which may be helpful in decision making where flow regimes are altered by water abstractions.
