Haematological Profiles of Lactating Nili-Ravi Buffaloes Under Heat Stress-Alleviated Conditions During Sub-tropical Summer Season

The experiment was conducted using forty two Nili-Ravi lactating buffaloes of Central Institute for Research on Buffaloes, Regional Station-Bir Dosanjh, Nabha, Patiala, Punjab to investigate the effect of heat stress-alleviated conditions on haematological profile in Nili-Ravi buffaloes during hot-dry (HD) and hot-humid (HH) season. All buffaloes were uniformly divided into two groups of twenty one in each group considering their lactation number, stage of lactation, body weight, dam's milk yield and milk yield in current lactation. Out of which ten buffaloes from each group were selected for blood sampling considering those above factors. The control (T0) group were kept in a separate shed without any extra nutrient supplementation and modification in microclimate and management. The treatment (T1) group was supplemented with niacin@6 gm/buffalo/day, yeast@10 gm/buffalo/day and mustard oil @150gms/buffalo/day. They were provided curtains and mist fans in the shed. Feeding time, frequency and type of ration were also altered. During HD period, T0 group exhibited higher (P<0.002, P<0.05) WBC (17.2 x 109 /L), and lymphocyte (12.52 x 109 /L) counts and lymphocyte per cent (69.46 %) than T1 group (12.32 x 10 9 /L, 7.32 x 10 9 /L and 59.68%, respectively). Similar results were recorded during hot humid season in T0 and T1 group. The neutrophil per cent differed significantly between T0 and T1 group under HD (P<0.001) and HH (P<0.006) season. The study indicated that heat stress during sub-tropical summer months affected the haematology of lactating buffaloes and the stress could be reduced through the change (use of fans and curtains, nutritional supplementations, and feeding alterations together in the form of one package) of microclimate

Reconsidering the World Heritage Potential of the Kinta Valley Post-Industrial Mining Landscape, Malaysia

The distinct landscape of the Kinta Valley is undeniably unique in its capacity in narrating significant phases and processes in Peninsular Malaysia’s history and culture. While tin mining brought about massive development to the Valley’s landscape, evidenced in the making of modern Kinta and Kampar Districts today, and Malaysia generally, this paper focuses on the potential of Kinta Valley as a World Heritage Listed mining cultural landscape. The rich cultural tapestry that is evident today across the Valley’s mining lands provides a significant living platform to understanding and appreciating the diversity of Malaysia’s cultural landscapes and in particular, offering a new perspective about industrial heritage values to Malaysia’s domestic and international tourism catchments. Keywords: Cultural Landscape as Heritage; Heritage Conservation; Post-Industrial Mining Landscape; Kinta Valley.eISSN: 2398-4287 © 2019.

Unravelling Layers of Colonial and Post-Colonial Open Space Planning and Heritage: The Identity of [Padang] Merdeka Square, Kuala Lumpur, Malaysia

In 1880, when the British moved their Federated Malay States administrative centre to Kuala Lumpur, the Padang quickly became a symbol of British economic and administrative colonisation, and a nucleus of the socio-cultural development of Kuala Lumpur. This paper discusses the layers of history, symbolism and cultural values that the Padang contributes to the socio-cultural tapestry of both Kuala Lumpur and Malaysia, and the lack of relevant planning and heritage measures to conserve these attributes and characteristics. The conclusions offer avenues to engage with pre- and post-colonisation that enable re-making and the conservation of the iconic space of Kuala Lumpur.Keywords: Urban open space; Merdeka Square; Kuala Lumpur City Hall; National Heritage Act 2005eISSN: 2398-4287 © 2019.

Consideration of pyloric stenosis as a cause of feeding dysfunction in children with cyanotic heart disease

Feeding difficulty has been reported at a higher incidence in infants with cyanotic heart disease and single ventricle physiology necessitating specialized feeding strategies. However, structural causes of feed intolerance in this subset of patients should not be ignored. This case series highlights three recent cases of pyloric stenosis in infants with left-sided obstructive lesions at our institution. In all three cases, the initial presumed diagnosis was feeding intolerance related to heart disease, and there was significant clinical improvement following identification and correction of pyloric stenosis

Design of Microcontroller-Based Portable Instrument for Measuring P-Wave Speed in Impact-Echo Method

Impact-echo method is widely used for non-destructive testing on concrete evaluation. One of the procedures of this method is determining P-wave speed by measuring travel time of P-wave ( between two transducers. For this purpose, a microcontroller-based portable instrument is developed. This research proposes a PIC microcontroller routine using interrupt-on-change and timer0 features. On concrete, impact waves reach the first accelerometer and will interrupt the main routine and start the timer0. When the waves reach the second accelerometer, the timer0 will be stopped. The value of the timer represents the travel time of P-wave. Therefore, the P-wave speed can be calculated. The routine is verified using controlled signal generated by internal PIC. The accurate result of the travel time measurements is presented. )t

Mechanistic insight in the selective delignification of wheat straw by three white-rot fungal species through quantitative 13C-IS py-GC–MS and whole cell wall HSQC NMR

Background The white-rot fungi Ceriporiopsis subvermispora (Cs), Pleurotus eryngii (Pe), and Lentinula edodes (Le) have been shown to be high-potential species for selective delignification of plant biomass. This delignification improves polysaccharide degradability, which currently limits the efficient lignocellulose conversion into biochemicals, biofuels, and animal feed. Since selectivity and time efficiency of fungal delignification still need optimization, detailed understanding of the underlying mechanisms at molecular level is required. The recently developed methodologies for lignin quantification and characterization now allow for the in-depth mapping of fungal modification and degradation of lignin and, thereby, enable resolving underlying mechanisms. Results Wheat straw treated by two strains of Cs (Cs1 and Cs12), Pe (Pe3 and Pe6) and Le (Le8 and Le10) was characterized using semi-quantitative py-GC–MS during fungal growth (1, 3, and 7 weeks). The remaining lignin after 7 weeks was quantified and characterized using ¹³C lignin internal standard based py-GC–MS and whole cell wall HSQC NMR. Strains of the same species showed similar patterns of lignin removal and degradation. Cs and Le outperformed Pe in terms of extent and selectivity of delignification (Cs ≥ Le >> Pe). The highest lignin removal [66% (w/w); Cs1] was obtained after 7 weeks, without extensive carbohydrate degradation (factor 3 increased carbohydrate-to-lignin ratio). Furthermore, though after treatment with Cs and Le comparable amounts of lignin remained, the structure of the residual lignin vastly differed. For example, Cα-oxidized substructures accumulated in Cs treated lignin up to 24% of the total aromatic lignin, a factor two higher than in Le-treated lignin. Contrarily, ferulic acid substructures were preferentially targeted by Le (and Pe). Interestingly, Pe-spent lignin was specifically depleted of tricin (40% reduction). The overall subunit composition (H:G:S) was not affected by fungal treatment. Conclusions Cs and Le are both able to effectively and selectively delignify wheat straw, though the underlying mechanisms are fundamentally different. We are the first to identify that Cs degrades the major β-O-4 ether linkage in grass lignin mainly via Cβ–O–aryl cleavage, while Cα–Cβ cleavage of inter-unit linkages predominated for Le. Our research provides a new insight on how fungi degrade lignin, which contributes to further optimizing the biological upgrading of lignocellulose.

Reduced graphene oxide-multiwalled carbon nanotubes hybrid film with low Pt loading as counter electrode for improved photovoltaic performance of dye-sensitised solar cells

In this work, the role of reduced graphene oxide (rGO) with hyperbranched surfactant and its hybridisation with multiwalled carbon nanotubes (MWCNTs) and platinum (Pt) nanoparticles (NPs) as counter electrode (CE) were investigated to determine the photovoltaic performance of dye-sensitised solar cells (DSSCs). Sodium 1,4-is(neopentyloxy)-3-(neopentyloxycarbonyl)- 1,4-dioxobutane-2-sulphonate (TC14) surfactant was utilised as dispersing and stabilising agent in electrochemical exfoliation to synthesise graphene oxide (GO) as initial solution for rGO production prior to its further hybridisation and fabrication as thin film. A chemical reduction process utilising hydrazine hydrate was conducted to produce rGO due to the low temperature process and water-based GO solution. Subsequently, hybrid solution was prepared by mixing 1 wt% MWCNTs into the produced rGO solution. TC14-rGO and TC14-rGO_MWCNTs hybrid solution were transferred into fluorine-doped tin oxide substrate to fabricate thin film by spraying deposition method. Finally, the CE films were prepared by coating with thin Pt NPs. Photoanode film was prepared by a two-step process: hydrothermal growth method to synthesise titanium dioxide nanowires (TiO2 NWs) and subsequent squeegee method to apply TiO2 NPs. According to solar simulator measurement, the highest energy conversion efficiency (η) was achieved by using CE-based TC14-rGO_MWCNTs/Pt (1.553%), with the highest short current density of 4.424 mA/cm2. The highest η was due to the high conductivity of CE hybrid film and the morphology of fabricated TiO2 NWs/TiO2 NPs. Consequently, the dye adsorption was high, and the photovoltaic performance of DSSCs was increased. This result also showed that rGO and rGO_MWCNTs hybrid can be used as considerable potential candidate materials to replace Pt gradually

Variation in the solubilization of crude protein in wheat straw by different white-rot fungi

Besides their unique ability to depolymerize cell wall components, white-rot fungi are known to assimilate nitrogenous compounds from substrates. This modification may change protein solubility and fermentation in the rumen. To investigate this, the crude protein (CP) in fungal treated wheat straw (3 fungal species, 2 strains each) was fractioned according to the Cornell Net Carbohydrate and Protein System (CNCPS) and assessed for in vitro protein fermentation using a modified gas production technique (IVGPN). Results showed that fungi increased fraction A (instantaneously soluble CP; ∼2.6 times) and B1 (rapidly degradable; ∼1.2 times); and decreased the slowly degradable fraction B3 (∼41.6%) and unavailable fraction C (∼48.3%). The IVGPN of straw treated with Ceriporiopsis subvermispora strains were not different to the control, but increased by 30.2 to 47.1% in Pleurotus eryngii and Lentinula edodes strains. The IVGPN was significantly (P <  0.01) correlated to all fractions of CP, except fraction B1 and B2 (intermediately degradable). All fungi also increased the arginine (∼56%) and lysine (∼15%) contents. This study shows the importance of assessing the protein solubilization by different fungal strains, which can uncover unique mechanisms in the cell wall depolymerization
