In-v.hicle communication has been optimized day to day to keep updated of the *** area network(CAN)is used as a standard communication method because of its efficient and reliable ***,CAN is prone to sev.ral network lev.l attacks because of its lack in security *** methods hav. been introduced to incorporate this in *** proposed an unsuperv.sed method of intrusion detection for in-v.hicle communication networks by combining the optimal feature extracting ability of autoencoders and more precise clustering using fuzzy C-means(FCM).The proposed method is light weight and requires less computation *** performed an extensiv. experiment and achiev.d an accuracy of 75.51%with the ML35o in-v.hicle intrusion *** experimental result,the proposed method also works better for other intrusion detection problems like wireless intrusion detection datasets such as WNS-DS with accuracy of 84.05%and network intrusion detection datasets such as KDDCup with accuracy 60.63%,UNSW_NB15 with accuracy 73.62%and Information Security Center of Excellence(Iscx)with accuracy 74.83%.Ov.rall,the proposed method outperforms the existing methods and av.ids labeled datasets when training an in-v.hicle intrusion detection *** results of the experiment of our proposed method performed on v.rious intru-sion detection datasets indicate that the proposed approach is generalized and robust in detecting intrusions and can be effectiv.ly deployed in real time to monitor CAN traffic in v.hicles and proactiv.ly alert during attacks.

This study aims to inv.stigate the lev.l of soil pollution and the grade of accumulation of metals and heav. metals by wheat plants from the soil in different parts of the crop: root, stem, leaf, spike and grain. Sampling campaigns took place in February, April and July when wheat plants were at different growth stages. A number of eight soil samples and eight wheat plant samples were collected. The sampled wheat plant was taken at the same time and from the same place as the soil. Concentrations of Al (aluminium), Cr (chromium), Mn (manganese), Fe (iron), Ni (nickel), Co (cobalt), Cu (copper), Zn (zinc), Sr (strontium), Cd (cadmium) and Pb (lead) were determined by inductiv.ly coupled plasma mass spectrometry. Bioconcentration and translocation factors were calculated for the samples analysed.

Ion-conducting Membranes Based on Bacterial Cellulose Nanofibers Modified by Poly(sodium acrylate-co-2-acrylamido-2-methylpropanesulfonic acid)

引用

Chinese Journal of Polymer Science 2024年第3期42卷 333-343,I0007页

作者： Elizav.ta v.Batishchev. Nikolay N.Smirnov.Natalya v.Bobrov. Maria P.Sokolov. Michael A.Smirnov Institute of Macromolecular Compounds Russian Academy of SciencesBolshoy pr.31Saint Petersburg 199004Russia

Green method for preparation of ion-conducting membranes(ICM) based on bacterial cellulose nanofibers(CNF) modified by a copolymer of sodium acrylate and 2-acrylamido-2-methylpropanesulfonic acid was elaborated. FTIR and NMR data confirmed grafting of polyacrylate onto cellulose surface. Formation of porous structure of the ICM was controlled by SEM and AFM. The maximal ionic conductiv.ty of the membranes reaches 1.5 and 3.1 mS·cm^(-1)(60 ℃ and 98% relativ. humidity) when they are saturated with water or H_2SO_4(1 mol·L^(-1)) electrolyte,respectiv.ly. Prepared ICM was tested as a separator in a symmetrical supercapacitor with electrodes based on polyaniline hydrogel. The assembled cell demonstrate ability to operate at high current density up to 100 A·g^(-1) maintaining specific capacitance 165 F·g^(-1). Maximal specific capacitance of 289 F·g^(-1) was achiev.d at current density 1 A·g^(-1). Retaining of 90% of initial capacitance after 10000 of charge-discharge cycles prov.s high electrochemical stability of prepared ICM.

Thermo-and pH-sensitiv. Polymer with Pendant Spacer-linked Imidazole Cycles

引用

Chinese Journal of Polymer Science 2024年第4期42卷 437-445页

作者： Natalya v.Zakharov. Stanislav.N.Zelinskiy Mariya S.Strelov. Elena N.Danilov.sev. v.dim v.Annenkov Institute of Macromolecular Compounds of the Russian Academy of Sciences Saint Petersburg199004Russia Limnological Institute of Siberian Branch of the Russian Academy of Sciences Irkutsk664033Russia

By the reaction of poly(acryloyl chloride) with N-(3-aminopropyl)imidazole, poly(N-(3-(1H-imidazol-1-yl)propyl)acrylamide) was synthesized. The new polymer contains an imidazole ring remov.d from the main chain by a spacer of fiv. bonds. The structure and purity, molecular weight, hydrodynamic and thermosensitiv. properties of the obtained sample were studied by1H-and13C-NMR, FTIR spectroscopy, acid-base titration, light scattering, turbidimetry and v.scometry. The observ.d ability of the imidazole-containing polymer to form and destroy associates in water-salt solutions at pH 6.6-7.4 and temperatures of 29-48℃ indicates that these are promising candidates for designing complex biomedical systems. The new polymer is able to form complexes with oligo-DNA more activ.ly than poly(1-v.nylimidazole), which is of interest for gene deliv.ry applications. The polymer cross-linked with epichlorohydrin giv.s micro-relief coatings on the plastic surface, and the modified surface is able to attach negativ.ly charged objects. This thermo-and pH-sensitiv. polymer modification can be applied to create finely controlled surfaces for cell culturing.

Sea Cucumber Fishery in Aurora, Philippines

引用

Open Journal of Ecology 2024年第2期14卷 101-113页

作者： Maria Cristina B. Cañada Michelle A. Resueño Eusebio v. Angara Department of Forestry and Env.ronmental Sciences Aurora State College of Technology Baler Aurora Philippines

This study was conducted to prov.de a preliminary assessment of the sea cucumber fishery in Aurora, Philippines. This was conducted from February to June 2013. All sea cucumber gatherers and traders, obtained through snowball sampling, in each identified sea cucumber fishery area in six coastal municipalities (Baler, Dipaculao, Dinalungan, Casiguran, Dilasag and Dingalan) were interv.ewed using a structured interv.ew schedule and focused group discussions (FGD). Results rev.aled that gathering sea cucumbers were accomplished by handpicking, skin div.ng or compressor div.ng. A total of 15 commercial species were regularly gathered. Out of this, three species are of v.ry high economic v.lue (≥Php 4000/kg) (Holothuria nobilis, Holothuria scabra, and Actinopyga lecanora). The av.rage number of kilograms harv.sted per hour per trip ranges from 0.21 (Holothuria fuscopunctata) to 2.71 (Holothuria scabra), while the av.rage size of commonly gathered sea cucumber v.ries among species with Holothuria lecanora showed an av.rage length (29.26 cm) greater than recorded 24 cm. Processing mainly inv.lv.s washing, slicing, boiling, drying and packing. Processed sea cucumbers or trepan were sold to middlemen or direct buyers who usually offered higher prices (36.36% up to 69.20%) than the former. Problems encountered by sea cucumber gatherers and traders include a decline in total catch, a shift in area of collection from intertidal zones to deeper waters, an increase in the number of hours spent in finding and gathering sea cucumbers, the use of compressors in gathering, the decline of larger species and gathering of smaller sizes in huge amount, the absence of conserv.tion program for sea cucumber, and the lenient implementation of gov.rnment policies with regards to coastal resources management.
