Abstract
An important factor affecting the climate is the amount of rain that falls in a given year. An imbalanced rainfall distribution results in periods of excessive rainfall over certain location that can increase the risk of flood, and contrarily a periods of drought, which hinder plant and crop growth. Therefore, a spatiotemporal assessment of rainfall concentration is important in case of Johor river basin (JRB) in identifying area that is prone to flood, and to ensure the utilisation of water resource can be optimise and conserve throughout the year. In this study, gridded-based CHIRPS rainfall dataset (period 1983–2018) was used to calculate rainfall concentration based on the concentration index (CI). In addition, the performance of Seasonality Index (SI) and Precipitation Concentration Index (PCI) was investigated to define the rainfall regime in JRB. The mapping of the spatiotemporal distribution of CI was done to understand the pattern and changes in the days of heavy rainfall across JRB. High CI is associated with strong physical processes like convection, while low CI can be construed as the result of regular patterns like the fronts' constant passage. The trend was then analysed with non-parametric Mann–Kendall (MK) at 95% significance level. The results showed that SI can give a better classification of rainfall regime in JRB than PCI, due to broader classification. Under SI classification, the rainfall regime in JRB was mainly characterised by ‘equable but with a definite wetter season’ type. Generally, the CI values is high (≥ 0.60) across the basin, varying from 0.61 to 0.72, with the highest in the north-western and western area. The shift in rainfall concentration was observed, as CI significantly increased at 27 grid points along the eastern border at the upstream and middle part of the basin. 25% rainiest days during the NE monsoon made up more than 67% and up to 83% of the annual rainfall for all grid points. Therefore, it is inferred high-intensity rainfall events contribute by the total rain in the basin, which give the highest overall percentage. The results enhance the knowledge on the local climate in Peninsular Malaysia (PM), and also give considerable important information to water resource management, flood mitigation plan and also valuable for agricultural planning.

Abstract
Background
Cervical cancer is caused by continuous infection of high-risk HPV. The timely and accurate diagnosis could contribute to prevent the damage from cervical cancer to female. Biopsy under the guidance of colposcopy is the gold standard for the diagnosis in cervical cancer which the accuracy is still questionable. We aim to analyze the deficiency and related risk factors of colposcopy guided point biopsy for cervical intraepithelial lesions by comparing the postoperative pathology of LEEP.
Methods
A retrospective analysis was performed on 1329 patients, they were all tested by HPV genotype with diversion hybrid gene chip technology using 21-type Geno Array Diagnostic Kit, after colposcopic point biopsy and LEEP surgery. All patients were enrolled in group according to the ASCCP 2012 guidelines, and biopsy examination using the German LEISEGANG photoelectronic colposcopy system under the guidance of colposcopy.
Results
Among all participants, 28.3% (376/1329) and 71.7% (953/1329) were found low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) by colposcopy guided point biopsy, respectively. 20.2% LSIL patients (76/376) were found HSIL after LEEP, and in those 76 new HSIL cases, HPV type 16, type 18, other 12 type (31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68) and rest HPV type were found 38.2% (29/76), 14.5% (11/76),43.4% (33/76) and 4.0% (3/76), respectively. In the 953 cases of HSIL diagnosed by colposcopy guided point biopsy (HSIL-PB), 1.6% cases (15/953) were found invasive cancer after LEEP and HPV16/18 infection rate was 86.7% (13/15).
Conclusion
In this study, we found HPV 16/18 positive patients had a higher risk in misdiagnosis by colposcopic biopsy, especially LSIL cases diagnosed by point biopsy. HPV16/18 infection should be a novel diagnostic biomarker in CIN diagnosis.
Specific and rapid visual detection of organophosphorus and carbamate pesticides in agricultural products by gold nanoparticles conjugated with aptamer

Published: October 2022

Abstract
Designing a fast, cheap and easy method which enables detection of the pesticide residue levels on-site is very important. In the present research, a sensitive nanobiosensor has been designed based on gold colloidal nanoparticles that could detect organophosphates and carbamates. It was synthesized using gold plasmonic nanoparticles by chemical growth method on grain particles. This nanobiosensor was optimized in the presence of different concentrations and volumes of aptamer, salt, etc. To detect pesticides by this nanobiosensor Trichlorfon and diazinon (OP) and Carbofuran and pirimicarb (Carb) were used. By interaction of the pesticides with the nanobiosensor, the appearance and color of the nanobiosensor changed markedly, which was visible to the naked eye. The results show, the sensitivity of this nanobiosensor is the lowest to diazinon and the highest to Carbofuran over the time. It seems that in the presence of Trichlorfon, the nanobiosensor designed in the beginning shows significant morphological changes in the nanostructures. The time required for incubation of samples of pesticide and nanobiosensor is determined to be about 10–15 minutes. Another interesting potential of colorimetric nanobiosensor is based on the extreme sensitivity of surface plasmon resonance of gold nanostructures to the surrounding media, which can be functionalized with specific biomolecules for specific detection. Therefore, there is a good potential to replace this new method with conventional methods.

Abstract
To explore the potential impact of immune microenvironment and gene mutation on the prognosis of patients with colon cancer. A colon cancer prognostic model was constructed based on cytokine-related genes. Colon cancer transcriptome sequencing data, clinical information, mutation information and cytokine-related gene lists were obtained from TCGA, GEO, UCSC, and ImmPort. The 112 genes of CRDGs were constructed by differential analysis and intersection with cytokine-related genes. Based on this gene set, a risk model was constructed, evaluated and validated, and PPI, GO and KEGG enrichment analyses were performed on this gene set. From the performance of the ROC of the training and validation models, this model has good predictive ability, and the risk score can be used as an independent factor for colon cancer prognosis. Immune infiltration and mutation analysis based on the risk model showed that Bcell, Tcell, and M2 were significantly decreased in the high-risk group, while M0 was increased. From the expression of mutated genes in risk groups, TTN, TP53, KRAS, APC, MUC16, and MUC4 have beneficial or adverse effects on prognosis. Independent prognostic analysis and drug sensitivity analysis revealed a certain clinical value of this model. In summary, The model constructed by CRDGs has good predictive ability and can be used as an independent factor for clinical prognosis. The immune microenvironment and some gene mutations have important effects on tumor prognosis.

Abstract
Rotary machines in industrial environment operates under various specifications and characteristics. When rotary machines are operating, various kinds of vibrations are generating including specific current operation states. In this way, lots of studies on anomaly detection and diagnostics of states with vibration analysis for rotary machines are conducted. However, if it is not for the robust dataset based accurate labeling considering dynamic environments for analysis criteria, it is challenged to identify various types of the rotary machines states and limited to correct decision making. For overcome these difficulties, this paper proposes Multi Combination Pattern Labeling (MCPL) method, which is to generate labels for fluent anomaly criteria and classification of rotary machine states considering dynamic industrial environment. MCPL induces FFT Pattern and Spectrogram Pattern reflecting inside vibration frequency characteristics and power pattern considering outer environment. Extracting inner and outside pattern, each pattern is combined for identifying convergence patterns, named MCP. Each MCP proceeds labeling process, named MCPL, then MCPL dataset is structured. MCPL dataset is verified based on Deep Neural Network(DNN) and Convolutional Neural Network(CNN). Presenting high accuracy and stable results, through MCPL based labels are possible to classify rotary machines states and detect anomalies under the convergence environment.
Cellulose nanocrystal films – Effect of electrolyte and lignin addition on self- assembly, optical, and mechanical properties
Authors: Parit Mahesh , Jiang Zhihua 
Published: October 2022

Abstract
Effect of electrolytes with various sizes (CsCl, NaCl), valencies (NaCl, CaCl2, AlCl3), pH (NaCl, NaOH) on the self-assembly, optical, and mechanical properties of CNC film was studied. The cross polarized optical microscopy, UV-Vis transmission spectroscopy showed that the chiral nematic to isotropic transition concentration was dependent on the type of counterion and its interaction with the CNC rods. Notably for large size and higher valency of counterion, lower transition concentration was needed. Electrolyte concentration also influenced the CNC film transparency and pitch. At lower electrolyte concentrations CNC film retained iridescence while at higher concentrations hazy film was obtained due to CNC aggregation and electrolyte precipitation, the maximum transparency was obtained near transition concentration. At low electrolyte concentration, the CNC film pitch was higher which may be due to large effective diameter of negatively charged CNC rods, increase in electrolyte concentration reduced the pitch due to suppression of electrical double layer. Addition of electrolyte also showed improvement in the tensile strength (upto 60%) and % strain (upto 170%) of CNC film. This may be due to the presence of ionic interaction between the sulfate ester groups of CNC and positively charged counter ions of electrolyte thereby improving the stress transfer between the rods. Further, the CNC/kraft lignin (KL) based transparent, UV protection films were designed by incorporating hydrogen peroxide treated KL (PBKL) optimized for its transparency and UV blocking properties. CNC/PBKL composite films showed superior %Transparency at 550 nm and %UV blocking at 400 nm compared to CNC/4-amino benzoic acid (4-ABA), a commercial UV-absorbent and most lignin based transparent composite films reported in literature.

Published: October 2022

Abstract

Environmental concerns become increasingly evident as technology progresses and the world's population expands. Kitchen ventilation is a subdivision of ventilation that deals with the treatment of air from kitchens. Grease, fumes, and odours are all problems that kitchen ventilation solves. As a result, a cost-effective chimney was chosen to assist civilians. The primary components for venting the kitchen air are the filter, fan, flue, and duct. In this work, the new geometry duct design is improved and analysed by ANSYS. The volume of hot flue gas and discharge of hot flue gas are calculated theoretically and also recommended standard dimensions and geometry to the industry. Academic contributions to chimney advancements are recognised in this study endeavour, and a research deficit is identified based on these objectives.
Autumn Leucojum autumnale L. and spring L. trichophyllum Schousb.: the same flower type for different seasons with a different pollination scenario
Authors: Muñoz-Rodríguez Adolfo Francisco , Barón Ignacio Camino , Ortega-Olivencia Ana 
Published: October 2022

Abstract

Some reproductive aspects of plant species may be conditioned by their flowering phenology. This might affect both the diversity and abundance of pollinators and the plants that constitute the community and, in turn, influence the degree of competition for pollinators. This study analyzed the plant floral display, floral rewards, and the pollination and breeding systems of two related species of Leucojum with different flowering phenology, the autumn-flowering L. autumnale L. and the spring-flowering L. trichophyllum Schousb. The main aim was to discover differences between both species that could be modeled by their differing flowering phenology. Our results showed that both species needed pollinators to reproduce sexually, with zero (L. trichophyllum) or almost zero values (c. 7.7%; L. autumnale) for fructification after self-pollination vs. over 90% after natural pollination (both species). Their flowers opened in the morning and closed at night, and neither produced nectar, only pollen as reward to pollinators. Plants of the L. autumnale population studied produced 1 to 4 inflorescences per plant vs. only 1 in L. trichophyllum, and the former presented a greater density of flowers per surface unit. Leucojum autumnale flowers were visited by Himenoptera in the morning and those of L. trichophyllum only received visits from two Coleoptera, these being most abundant at sunrise and sunset, whereas in the middle of the day they visited Cistaceae flowers. This latter occurrence represents facilitation rather competition in relation to visiting hours.

Published: October 2022

Abstract
The aluminate nano-powders Al2XO4 (X = Cd, Ni and Co), crystallizing in a cubic spinel, were prepared by combustion method at 900°C. The effects of cations on the structure, optical properties and distribution of the cations as well as the binding energy of the samples were studied by X-ray diffraction (XRD), UV-Vis diffuse reflectance and FT-IR) spectroscopy. The XRD analysis confirmed the spinel structure of all samples, and showed that the average crystallite size of Al2XO4 increases from 23.89 to 32.72 nm, while the lattice parameter changes from 8.0490 to 8.1066 Å when going from Ni to Co. As expected, the FT-IR spectroscopy of Al2XO4 showed the presence of the fundamental absorption peaks in the region (400–745 cm− 1 ), confirming the formation of the aluminate spinels. The slight shift toward longer wavenumbers is due to the low electronegativity of Cd. The forbidden bands (Eg), determined by diffuse reflectance, were found to be 3.78, 3.82 and 3.75 eV respectively for Al2CdO4, Al2NiO4 and Al2CoO4, assigned to the charge transfer O2−: 2p → X2+: d orbital, making our spinels good candidates for optoelectronic and photocatalytic applications.

Abstract
The South Escarpment of the Bamileke Plateaus (ESPB) is located on the LVC and is part of the HTOC. It is subject to many risks related to mass movements. This region has significant potential for agro-pastoral activities. It is for this reason that the demographic explosion is important there. The population in place practices many activities and owns several assets. This is the essence of the vulnerability to mass movements in this region. This vulnerability is human and material. Assessing the risk of mass movement also requires an assessment of vulnerability. Field campaigns have made it possible to identify the various vulnerable sites. Falling rocks, landslides and subsidence are the main mass movements in the region. The mass movement density map and probable area map highlight these mass movements. By questioning the populations and using the documents, we estimated the losses. The population is estimated at around 195.181 inhabitants. The estimated loss of agro-pastoral activities is 62.251.150 FCFA or 115.455.96 USD. The ESPB is covered by approximately 279.0335 km of road. It is full of many homes and public buildings. The estimated loss of buildings and properties amounts to 2778509.700 FCFA or 5151001.33 USD. By questioning the populations and using the documents, we estimated the losses.

Morphological plasticity of six tree species with different light demands growing in multi-layered deciduous forests in Central Europe
Authors: Bartkowicz Leszek , Paluch Jarosław 
Published: October 2022

Abstract
Tree allometry is a plastic feature and scaling parameters may considerably vary depending on phylogeny, life strategies, growth conditions and ontogeny. We hypothesized that in multilayered forests growing on rich sites and driven by stand dynamics without stand-replacing disturbances, light is a primary driver of allometric relationships and thatthe morphological plasticity of tree species is closely associated with their shadetolerance. We quantified and compared the morphological properties of six species forming a shade tolerance gradient: Alnus glutinosa(L.) Gaertner,Quercus roburL.,Fraxinus excelsior L.,Ulmuslaevis Pall.,Tilia cordata Miller, andCarpinus betulus L.The relationships between tree height and local stand density as predictors and dbh, crown width, crown length and crown volume as response variables were characterized. We found thatin the lower stand layer the values of crown parameters increased with tree height at a lower ratein light adapted than in shade tolerant species. In contrast, the response of morphological traits on competition was stronger in light adapted than in shade tolerant species.The crown widthtocrown length ratio was not associated with light demand. Except for the different allocation pattern of ash, between-species differences in the slenderness ratio were insignificant. Allometry and sensitivity to competition was different in trees growing in the upper and lower stand layer. Our results show that the dichotomy of basic growth strategies of stress tolerance or stress avoidance is too simplistic and does not encompass social status and species-specific features such asapical control.

Abstract

Biopesticides based onBacillus thuringiensis(Bt) are widely used to control agricultural pests. These products are efficient and have high specificity to target insects. However, there are concerns about their impact on non-target organisms.Ceraeochrysa claveri, is a polyphagous predator with important value in the biological control of insect pests in crops of economic interest. This study aimed to analyze the effects ofB. thuringiensisserovaraizawaiCG-91 (Bta) on the post-embryonic development ofC. claveri. Neonate larvae ofC. claveriwere fed withDiatraea saccharaliseggs contaminated with different concentrations of Bta (0.62, 1.25, 2.50, and 5.00 g.L-1) until your pupation. Samples of the midgut larvae were collected for histological and ultrastructural analysis, and the larval and pupal inviability data were collected at the end of the respective developmental stages. After the emergence of adult insects, were considered inviable those with morphological alterations. To evaluate the reproduction, adult insects couples were formed, and the oviposition was collecteds. No significant differences in the viability of eggs, larvae, pupae, and adults ofC. clavericontaminated with Bta were reported. Midgut analyses did not reveal cellular damage in the epithelium, indicating a possible lack of insecticidal proteins receptors. The oviposition and their viability were similar between treated and control groups. Our results demonstrated that Bta did not affect the post-embryonic development ofC. claveri. This illustrates that the combined use of Bta andC. claverifor the biological control of arthropod pests can be a sustainable strategy for integrated pest management.
