We have observed the low-mass protostellar source IRAS 15398−3359 at a resolution of 0.″2–0.″3, as part of the Atacama Large Millimeter/Submillimeter Array Large Program FAUST, to examine the presence of a hot corino in the vicinity of the protostar. We detect nine CH3OH lines including the high-excitation lines with upper-state energies up to 500 K. The CH3OH rotational temperature and the column density are derived to be

, indicating that the emitting region of CH3OH is much smaller than the synthesized beam size and is not resolved. The emitting region of three high-excitation lines, 183,15–182,16, A (E
u = 447 K), 193,16–192,17, A (E
u = 491 K), and 203,17–202,18, A (E
u = 537 K), is located within the 50 au area around the protostar and seems to have a slight extension toward the northwest. Toward the continuum peak, we also detect one emission line from CH2DOH and two features of multiple CH3OCHO lines. These results, in combination with previous reports, indicate that IRAS 15398−3359 is a source with hybrid properties showing both hot corino chemistry rich in complex organic molecules on small scales (∼10 au) and warm carbon-chain chemistry rich in carbon-chain species on large scales (∼100–1000 au). A possible implication of the small emitting region is further discussed in relation to the origin of the hot corino activity.
Searching for Double-line Spectroscopic Binaries in the LAMOST Medium-resolution Spectroscopic Survey with Deep Learning
Authors: Zheng Zepeng , Cao Zhong , Deng Hui , Mei Ying , Tan Lei , Wang Feng
Published: May 2023

Double-line spectroscopic binaries (SB2s) are a vital class of spectroscopic binaries for studying star formation and evolution. Searching for SB2s has been a hot topic in astronomy. Although considerable efforts have been made with fruitful outcomes, limitations in automation and accuracy still persist. In this study, we developed a convolutional neural network model to search for SB2 candidates in LAMOST medium-resolution survey (MRS) data release (DR) 9 v1.0 by detecting double peaks in the cross-correlation function (CCF). We first generated a large number of spectra of single stars and binaries using the iSpec spectral synthesis software. The CCFs of these synthesized spectra were then calculated to form our training set. To efficiently detect the peaks of the CCFs, we applied a Softmax function-based noise reduction method. After testing and validation, the model achieved an accuracy of 97.76% in the testing set and was validated for more than 90% of the sample in several published SB2 catalogs. Finally, by applying the model to examine approximately 1.59 million LAMOST-MRS DR9 spectra, we identified 728 candidate SB2s, including 281 newly discovered ones.

Checklist of national key protected wild plants on the Qinghai-Tibetan Plateau
Authors: Chen Ronglian , Zhang Faqi , Chen Shilong , Chi Xiaofeng
Published: May 2023

Qinghai-Tibetan Plateau is a global biodiversity hotspot due to the unique geographical environment. However, there are few reports on the list of national key protected plants and the distribution pattern of their diversity in this area. Based on the flora and online database, this paper summarised the species diversity and distribution patterns of national key protected wild plants on the Qinghai-Tibet Plateau.

The results showed that there were 350 species of national key protected wild plants on the Qinghai-Tibetan Plateau, belonging to 72 families and 130 genera. Amongst them, 22 species were under class I protection, 328 species were under class II protection and 168 species were endemic to China. Its endangered status involves EW 1 species, CR 17 species, EN 90 species, VU 90 species, NT 30 species, LC 60 species and DD 62 species. Species diversity declined gradually from the southeast to the northwest with hotspots located within Sanjiang Valley subregion (ⅢE14a). The list of national key protected wild plants and their diversity and distribution patterns in the Qinghai-Tibetan Plateau can provide basic data for the conservation of regional biodiversity and the formulation of conservation strategies.
Review and guide to the isopods (Crustacea, Isopoda) of littoral and sublittoral marine habitats in the Southern California Bight
Authors: Stebbins Timothy D. , Wetzer Regina
Published: May 2023

The isopod crustaceans reported from or expected to occur in littoral and sublittoral marine habitats of the Southern California Bight (SCB) in the northeastern Pacific Ocean are reviewed. A total of 190 species, representing 105 genera in 42 families and six suborders are covered. Approximately 84% of these isopods represent described species with the remaining 16% comprising well-documented “provisional” but undescribed species. Cymothoida and Asellota are the most diverse of the six suborders, accounting for ca. 36% and 29% of the species, respectively. Valvifera and Sphaeromatidea are the next most speciose suborders with between 13–15% of the species each, while the suborder Limnorioidea represents fewer than 2% of the SCB isopod fauna. Finally, the mostly terrestrial suborder Oniscidea accounts for ca. 5% of the species treated herein, each which occurs at or above the high tide mark in intertidal habitats. A key to the suborders and superfamilies is presented followed by nine keys to the SCB species within each of the resultant groups. Figures are provided for most species. Bathymetric range, geographic distribution, type locality, habitat, body size, and a comprehensive list of references are included for most species.
Du Lmazɣi à Tamazight. Les usages écrits du Tachelhit au xix e et xx e siècle
Authors: Aboulkacem-Afulay El Khatir
Published: May 2023

Ce travail s’intéresse aux usages écrits du tachelhit, un des parlers de la langue berbère au Maroc, au cours du xix e et xx e siècles. L’importance de ces deux derniers siècles réside dans la condensation des types des écritures et leurs développements compte tenu du contexte historique particulier. Si les écritures localement ancrées, comme les textes de prédication religieuse composés au sein des zaouïas et les correspondances personnelles, continuent de fleurir et de se diversifier, l’initiation des projets d’exploration scientifique a permis l’apparition d’autres types comme les recueils de productions orales et les notices historiques et ethnographiques. Ce genre d’écritures sera par la suite institutionnalisé sous le protectorat français et, après l’indépendance, la situation marginale de la culture amazighe a engendré la mobilisation de l’écriture dans la revendication identitaire favorisant l’émergence d’une production littéraire moderne.
La langue kabyle en situation urbaine : le cas du parler des Ath Abbès dans l’Oranie
Authors: Philippou Maria , Ouaras Karim
Published: May 2023

Cette recherche en cours se propose d’interroger le fonctionnement des langues premières en contexte de migration locale en mettant l’accent sur le cas de la langue kabyle dans l’Oranie et son évolution à travers l’espace et le temps sans avoir la prétention de le faire dans une perspective globalisante. La présente contribution se focalisera sur le parler des Kabyles venant des Ath Abbès, localité située au Sud de la vallée de la Soummam, Béjaïa, de la fin du xix e à nos jours. Enclenchée au lendemain de l’insurrection d’El Mokrani et de Cheikh el Hadad (1871), la migration des Kabyles de la confédération des Ath Abbès vers d’autres régions d’Algérie se poursuivra au gré des contextes historiques et socio-économiques jusqu’à l’heure actuelle. La migration locale a généré des situations de mobilités sociales accompagnées de représentations et d’attitudes vis-à-vis de la langue kabyle et des autres langues avec lesquelles elle est en contact. Par conséquent, le milieu urbain qui draine toutes ces populations venant d’un ailleurs proche ou lointain donne à observer des phénomènes ethno-sociolinguistiques complexes par leurs composantes, leurs trajectoires et les enjeux d’homogénéisation et de conformisme linguistique qui les guettent. Basée sur des observations de terrain et une approche qualitative, cette recherche se donne pour objectif de retracer l’histoire sociale de la langue kabyle (parler des Ath Abbès) à Oran et évaluer les fonctions qui lui sont assignées en fonction des contextes historiques, et ce sur quatre générations.
Au front : les journaux de tranchées

Published: May 2023

Réalisés par des soldats pour des soldats durant toute la Grande Guerre sur le front occidental comme oriental, les journaux de tranchées constituent une exceptionnelle source pour étudier les conditions matérielles et morales de vie des poilus. Dans tous, textes et dessins usent de l’humour en abondance. Le musée de l’Armée conserve un corpus de quarante-neuf titres. Leur analyse permet de distinguer quatre thèmes particulièrement récurrents : l’humour patriotique, les railleries contre les embusqués, les conditions de vie et l’autodérision.

En 2018, dans son discours de clôture de la conférence du Royal United Services Institute, le général Sir Mark Carleton-Smith disait accorder « une grande importance à […] un code du commandement qui met en avant l’irrépressible sens de l’humour du soldat britannique ». Est-ce un effet d’annonce ou existe-t-il une réalité qui fait du sens de l’humour un atout militaire ? Un sujet qui, s’il peut prêter à sourire, est plus sérieux qu’il n’y paraît.

Une souveraine à l’armée : la figure de la reine de Prusse dans la caricature napoléonienne
Authors: Cheminat Cyprien
Published: May 2023

Le déclenchement du conflit avec la Prusse en octobre 1806 va offrir aux satiristes français l’occasion de déployer leur verve contre le couple royal prussien, notamment la reine qui a l’outrecuidance d’accompagner son mari à l’armée. Portées par la réduction à néant des espoirs de paix, mais aussi par la propagande officielle, les caricatures vont largement participer au processus de décrédibilisation politique de Louise de Mecklembourg-Strelitz, tour à tour présentée comme une furie belliqueuse, une épouse infidèle et une mauvaise souveraine.
L’humour juif comme antidote à la mort
Authors: Korsia Haïm
Published: May 2023

On ne parle jamais d’un humour chrétien, musulman ou bouddhiste, mais d’un humour juif oui. Peut-être parce que la seule manière pour le peuple juif de s’extraire des vicissitudes infinies de l’histoire est d’en rire. Rire de soi, de ses malheurs et de la confiance absolue en un futur toujours démenti par les faits. Rire pour vivre. Rire pour exister. Car le rire permet de faire tomber toutes les citadelles, en particulier celle de la peur. Et quelle plus grande peur que celle de la mort ?
Francophonie et francophilie littéraires

Malgré sa rhétorique épique, Texaco est plus écrit qu’oral, français que créole, élitaire que populaire. Si Patrick Chamoiseau n’est guère parvenu à en faire l’épopée de la Martinique, ce roman n’en reste pour autant pas à la reproduction des valeurs des élites métropolitaines : si c’est bien à eux, plus qu’au petit peuple, que son roman est destiné qu’il le veuille ou non, c’est en tant que machine de guerre, destinée à frapper en son cœur l’imaginaire colonial de l’Occident.

Afane Obame interprète des signes prémonitoires. Sa confrontation avec le pasteur Gambier révèle des erreurs de jugement dans sa lecture des signes. L’ambivalence des discours de ces deux chefs spirituels est évaluée à la lumière du signe obame « l’épervier », symbolique d’usurpation et de sorcellerie dans la culture fang. Sur la base des contradictions qui s’en dégagent, cet article fait dialoguer Roland Barthes, Jacques Derrida, Mikhaïl Bakhtine et Homi Bhabha sur le concept de réel.
L’intersectionnalité comme outil réflexif et pratique politique. Trajectoires de politisation des Foulards violets
Authors: Direnberger Lucia , El-Shikh Inès
Published: May 2023

Cet article prend pour objet les trajectoires de politisation des femmes mobilisées au sein d’un collectif, Les Foulards violets. Ce collectif, créé en 2019 à Genève, se donne pour objectif de lutter contre le racisme et le sexisme que subissent les femmes musulmanes, en particulier celles qui portent un foulard. L’intersectionnalité est saisie (1) comme une modalité d’expression d’expériences d’oppressions multiples qui structurent les mondes sociaux des femmes vivant à Genève et (2) comme un outil et une pratique politiques de ce collectif. L’article s’appuie sur des fonds d’archives militantes et sur dix entretiens approfondis avec huit militantes des Foulards violets et deux militantes de la Grève des femmes*/grève féministe, dont les carrières s’inscrivent initialement dans les mondes associatifs. Il s’agit d’analyser les espaces d’entre-soi comme outil privilégié de réflexivité de genre et de race, mais aussi pour la mise en commun des expériences et la lutte contre les oppressions multiples.
Une double négation
Authors: Lambertucci Mann Sabina
Published: May 2023

L’énonciation d’une double négation inaugure la reprise d’un deuxième temps d’une cure après une interruption décidée par la patiente. Cette formulation surprend l’analyste qui, dans un temps second, s’étaye sur « La négation ». Cet appel au père de la psychanalyse a permis de tiercéiser des mouvements transféro-contre-transférentiels particulièrement intenses. Par des allers-retours entre les deux temps de l’analyse, l’auteure évoque une première période marquée par la difficulté de la patiente à se souvenir et à accomplir le travail de deuil lié à la perte de sa mère ; une période de latence, caractérisée par l’interruption du traitement, véritable agir de transfert, a permis à la patiente d’assumer une position active. Elle a ainsi quitté l’objet pour ensuite, lors de la deuxième partie du traitement, le rechercher et le (re)trouver vivant. La double négation traduit alors, chez cette patiente, le début d’un nouveau fonctionnement psychique où la compulsion à soigner laisse la place à la remémoration de premiers souvenirs d’enfance.
La réaction thérapeutique négative : une expression agie de la négation ?
Authors: Pons-Nicolas Sylvie
Published: May 2023

Il est fréquent qu’une réaction thérapeutique négative soit actuellement évoquée lorsque l’analyse bute sur des résistances sévères qui font courir le risque d’une analyse interminable. Freud, cependant, a proposé une théorie spécifique de cette notion en constatant la logique paradoxale à l’œuvre : l’apparition d’une réaction négative lorsqu’un symptôme a été résolu, avec un renforcement de la souffrance et une aggravation de l’état de l’analysant. Comment comprendre le fait que certains analysants puissent ainsi basculer dans une négativité destructrice ? Dans cet article, l’auteur après avoir suivi le cheminement de l’élaboration de cette modalité de résistance dans la pensée de Freud, en appui sur la clinique, propose d’en illustrer le déploiement à la lumière des travaux de certains de ses successeurs.
« Vous – ma mère – non. » Dénégation chez un enfant et son analyste
Authors: Rosenberg Dinah
Published: May 2023

Cet article interroge les conditions d’émergence du jeu et de la dénégation dans une cure d’enfant. La dénégation, tel que Freud l’introduit dans l’article de 1925, conjugue essentiellement trois termes dont l’un est l’adresse transférentielle et les deux autres sont en conflit. Dans cette cure la haine et l’agitation étaient au premier plan. C’est à partir de l’expression directe du rejet qu’apparaît l’adresse qui permet d’envisager les deux termes en conflit. Le jeu et la curiosité intellectuelle sous forme d’un intérêt pour la mécanique peuvent alors émerger dans la cure et avec l’analyste. Cependant, le jugement de réalité reste précaire et nécessite donc son rétablissement chez l’analyste par le biais d’un travail de la négation chez celle-ci, c’est-à-dire d’un travail visant à retrouver l’objet d’une adresse pour entrer en contact avec ses propres mouvements contre-transférentiels par leur dénégation.

Le psychanalyste Josef Bernhard Lang et son patient-écrivain Hermann Hesse : regards croisés
Authors: Martin Carole
Published: May 2023

Le recueil, Hermann Hesse Briefwechsel mit seinem Psychoanalytiker Josef Bernhard Lang, met au jour la relation médicale, amicale et artistique entre le psychanalyste Josef Bernhard Lang et son patient-écrivain, Hermann Hesse. Sa lecture offre au monde littéraire et psychanalytique le portrait singulier et peu connu du Docteur Lang, un homme discret en recherche perpétuelle de vérité et de savoir qui fut une grande source d’inspiration et d’adaptation pour l’œuvre Hessienne. En la personne de Lang, Hesse découvre le traitement psychanalytique, la doctrine gnostique, mais aussi la peinture à l’aquarelle. D’une correspondance au départ strictement médicale permettant au patient de convenir de ses rendez-vous avec son psychanalyste, la relation va se métamorphoser en une longue amitié entre les deux hommes complices partageant leur attrait et goût commun pour la littérature allemande, les réflexions philosophiques, les arts, et la musique. Cette correspondance est également un riche témoignage du lien et de la dynamique interdisciplinaire qu’entretiennent la psychanalyse et la littérature.
Modeling and analysis of release strategies of sterile mosquitoes incorporating stage and sex structure of wild ones
Authors: Huang Mingzhan , Yu Xiaohuan , Liu Shouzong
Published: May 2023

This paper proposes and studies a switched interactive model of wild and sterile mosquitoes with stage and sex structure. Sterile males are released periodically and impulsively and remain sexually active for time $ \bar{T} $. We investigate the dynamical behavior of the system when the release period $ T $ is shorter than the sexual lifespan $ \bar{T} $, corresponding to a relatively frequent release. We first determine two important thresholds, $ m_1^* $ and $ m_2^* $, for the release amount $ m $ and prove the exponential asymptotic stability of the extinction equilibrium. Using fixed point theory, we establish the existence of positive periodic solutions for $ 0 < m < m_1^* $ and $ m_1^*\leq m < m_2^* $. Furthermore, by applying the comparison theorem of monotone systems, we demonstrate that the extinction equilibrium is globally asymptotically stable when $ m\geq m_2^* $. Finally, numerical examples are presented to confirm our theoretical results.
Linear superposition and interaction of Wronskian solutions to an extended (2+1)-dimensional KdV equation
Authors: Cheng Li , Zhang Yi , Hu Ying-Wu
Published: May 2023

The main purpose of this work is to discuss an extended KdV equation, which can provide some physically significant integrable evolution equations to model the propagation of two-dimensional nonlinear solitary waves in various science fields. Based on the bilinear Bäcklund transformation, a Lax system is constructed, which guarantees the integrability of the introduced equation. The linear superposition principle is applied to homogeneous linear differential equation systems, which plays a key role in presenting linear superposition solutions composed of exponential functions. Moreover, some special linear superposition solutions are also derived by extending the involved parameters to the complex field. Finally, a set of sufficient conditions on Wronskian solutions is given associated with the bilinear Bäcklund transformation. The Wronskian identities of the bilinear KP hierarchy provide a direct and concise way for proving the Wronskian determinant solution. The resulting Wronskian structure generates $ N $-soliton solutions and a few of special Wronskian interaction solutions, which enrich the solution structure of the introduced equation.

FM-Unet: Biomedical image segmentation based on feedback mechanism Unet
Authors: Yuan Lei , Song Jianhua , Fan Yazhuo
Published: May 2023

With the development of deep learning, medical image segmentation technology has made significant progress in the field of computer vision. The Unet is a pioneering work, and many researchers have conducted further research based on this architecture. However, we found that most of these architectures are improvements in the backward propagation and integration of the network, and few changes are made to the forward propagation and information integration of the network. Therefore, we propose a feedback mechanism Unet (FM-Unet) model, which adds feedback paths to the encoder and decoder paths of the network, respectively, to help the network fuse the information of the next step in the current encoder and decoder. The problem of encoder information loss and decoder information shortage can be well solved. The proposed model has more moderate network parameters, and the simultaneous multi-node information fusion can alleviate the gradient disappearance. We have conducted experiments on two public datasets, and the results show that FM-Unet achieves satisfactory results.

Breast cancer is one of the life threatening cancer that leads to the most death due to cancer among the women. Early diagnosis might help to reduce mortality. Thus, this research aims to study on different approaches of the deep learning neural network model for breast cancer early detection for better prognosis. The performance of deep learning approaches such as Artificial Neural Network (ANN), Recurrent Neural Network (RNN) and Convolution Neural Network (CNN) are evaluated using the dataset from the University of Wisconsin. The findings show ANN achieved high accuracy of 99.9 % compared to others in detecting breast cancer. ANN is able to deliver better results with the provided dataset. However, more improvement needed for better performance to ensure that the approach used is reliable enough for breast cancer early diagnosis.
Secured Transfer and Storage Image Data for Cloud Communications
Authors: Mohammad K. Abdul-Hussein  , ALRikabi Haider TH.Salim
Published: May 2023

In cloud computing, resources are used to communicate instead of local servers or individual devices. However, sharing resources among several users is a difficult issue in cloud communication. Cryptography and steganography techniques are used for cloud storage to address data security challenges. This paper presents a novel method for securely encrypting image data for transmission and link exchange with a cloud storage service. There are two phases to accomplish the encryption process, the first phase encrypts the image file by XORing it with a random key that is generated by a new hybrid of the chaotic map. The second phase converts the encrypted image format to audio format to add another layer of security and improve secure image data transfer. The random key is generated using a hybrid chaotic map and has the benefit of having more than 10256 key spaces and the necessary level of security. Based on a statistical analysis of the encryption, the quality of the image is evaluated using several criteria, and the results demonstrate the algorithm's ability to accomplish resist encryption

This study aimed to evaluate cassava genotypes to identify the ones with the best nutritional values for ruminant diets. Nine genotypes were used: Amansa Burro (BGM 549), Aramaris (BGM 116), Brasília, Cambadinha (BRS Guaíra), Curvelinha, Engana Ladrão (BGM 1269), Trouxinha (BGM 1468), BRS Gema de Ovo, and BRS Dourada. A completely randomized block experimental design with nine treatments (genotypes) and three blocks (replicates) were employed. The roots were analyzed for dry matter production (DMP) in tonnes per hectare, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), starch, and in vitro dry matter digestibility (IVDMD). The multivariate analysis was carried out using Ward’s hierarchical agglomerative clustering based on Mahalanobis distance. The groups formed were evaluated by Scott-Knott test. The group formed by genotype Engana Ladrão was chosen as the best one for having the highest DMP t ha-1 and IVDMD values and the lowest NDF and ADF contents.

Published: May 2023

An experiment was conducted to evaluate the effect of diets with reduced energy level content, supplemented with carbohydrase, on broiler performance and the coefficient of metabolizability of nutrients. A total of 720 one-day-old male Cobb-500 chicks were distributed in a completely randomized design, with six treatments, eight repetitions of 15 birds each. The treatments were: (1) a positive control, basal diet to meet the requirements of broiler chickens (PC); (2) a negative control, basal diet with a reduction of 80 kcal kg-1 (NC); (3) NC + alphagalactosydase; (4) NC + xylanase; (5) NC + xylanase and alphagalactosydase, and (6) NC + enzymatic blend (alphagalactosydase, xylanase, pectinase and amylase). The nutrient digestibility was not improved by use of enzymes. At 7 days of age, the broilers which were fed diets supplemented with enzymes showed a lower feed intake (FI) and better feed conversion ratio (FCR) than the broilers fed on PC.  Both the NC and enzymatic blend resulted in a worse performance of the broilers at 21, 35 and 42 days old. The use of alphagalactosydase and xylanase, isolated or in combination, in a corn-soybean meal-based diet is effective in improving the growth performance of broilers fed energy-reduced diets.

Wooden breast myopathy (WB) strongly affects the poultry industry mainly in terms of consumers rejection and economical loses, due to morphological changes in broiler muscle tissue and consequently low meat quality. The aim of this study is to evaluate the histomorphometry of muscle fibers of breast fillets of broilers with severity levels of WB myopathy. The histological evaluation considered 30 samples of the pectoralis major muscle and the level of WB myopathy (ten normal fillets, ten moderate fillets, and ten severe fillets). Fillets with a severe level of WB present low average fiber number, high average fiber diameter, low percentage of fibers with diameter of less than 20 µm, low percentage of fibers with diameter between 20 and 40 µm, and high percentage of fibers with diameter between 40 and 70 µm. Fiber cross-sectional area is greater in fillets affected by moderate and severe WB. Thus, fillets with a severe level of WB damage the muscle fiber structure and contribute more severely to the degenerative processes of breast meat.

Published: May 2023

Plastic industry development has increased the amount of plastic waste, including LDPE plastic film, therefore LDPE waste processing becomes essential, such as thermal or catalytic cracking. Cracking is the breakdown of complex hydrocarbons into simple and commercial hydrocarbons (C3-C40). The catalytic cracking is preferred due to lower temperatures, which is 200-300°C instead of 500-700°C. In this study, catalyst selection, acid impregnation of catalyst, catalyst loading (wt%), N2-gas-purging, feed-to-solvent weight-ratio, temperature, and reaction time were studied to determine the most suitable process condition to obtain the highest liquid fraction. In this study, the catalytic cracking was conducted at 20 bar with kerosene as solvent, with and without N2-gas-purging at several temperatures (265 and 295°C), solvent-to-feed weight-ratios (5:1 and 4:1), catalyst types (bentonite, SiO2 and ZSM-5), catalyst loading (wt%) (1.0wt%; 5.0wt%; 7.0wt%; 9.0wt%; 10.0wt%), and reaction time (1-3 hours). The best results were with N2-gas-purging using 10.0wt%-bentonite in (5:1) solvent-to-feed weight-ratio for 1 hour at 295οC produced 54.9wt% of liquid fraction and without N2-gas-purging at 265°C produced 54.5wt% of liquid fraction, indicating the possibility of N2-gas-purging exclusion in future studies. Additionally, this study has promoted bentonite as a potentially viable catalyst for LDPE plastic waste catalytic cracking.

The addition of zinc oxide (ZnO) as impregnation for activated carbon (AC) with the hydrothermal method has been performed in this research. Vetiver distillation waste has been used as a precursor for activated carbon synthesized with pyrolisis methods. Carbon is activated by a chemical process using KOH. Enhancement of amorph structure and function group by addition of zinc oxide has been characterized by Raman Spectroscopy, Fourier Transform Infra-Red (FT-IR), and X-Ray Diffraction (XRD). Furthermore, cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) has been done to show the electrochemical properties enhancement of the ZnO/AC compared to pristine AC. At the current density of 1 A/g, the specific capacitance of VRW-ACM has a value of 277 F/g. After the impregnation process, the specific capacitance of VRW-ACM-ZnO has been improved by 44.4% compared to VRW-ACM. The result showed that the activated carbon-based vetiver root waste impregnated with ZnO has the potential to be applied as supercapacitors electrodes.

Authors: Perera M. A. G. P. , Priyankara N. H.
Published: May 2023

Disposal of Municipal Solid Waste (MSW) has become a serious problem all over the world which is affected by the rising population and rapid urbanization. Most of the developed countries tend to proceed with engineered landfilling or incineration of solid waste while developing countries continue with open dumping. Most of these open dump sites are located on marshy lands or low lying land areas due to the high demand for prime lands in city areas, and they are expanded in vertical direction, saving the horizontal spaces. Therefore, physical, chemical and shear strength properties of MSW are timely important to overcome the stability failures of the dump sites during the operational period and after the closure of the dump sites. In this study, engineering properties of MSW were investigated using several laboratory experiments for disturbed waste samples collected from Meethotamulla dump site. In order to represent the aging effect of MSW, samples were extracted at different depths and variation of geotechnical properties with aging was analysed. Based on the laboratory test results, it can be noted that MSW in open dump sites in wet zone of Sri Lanka mainly consists of fine residue, aggregated soil, polythene and textiles. Further, higher shear strength parameters were obtained for MSW due to presence of textiles within the waste body. As such, it can be concluded that, it is necessary to consider the influence of textiles in analyzing the stability of open dump sites.

Published: May 2023

Significant safety challenges can arise at tunnelling works as they are conducted in semi-enclosed environments. This study aimed to develop a safety risk assessment framework for drill and blast tunnel construction in Sri Lanka. Tunnelling expert surveys in three sites were used for collecting the necessary data. Initially, a Risk Score Analysis was conducted to identify the critical hazardous events. They were identified as: direct spraying of concrete on eyes and skin, being exposed to noxious dust, and constant exposure to noxious noise. A Bow Tie Analysis was conducted to analyse each critical hazardous event, identifying their causes, preventive measures, recovery measures, and consequences. A probability-based Event Tree Analysis that shows all possible outcomes following the success or failure of protective barriers was also conducted. For example, according to the event tree analysis of ‘direct spraying of concrete on eyes and skin,' there is an overall probability of 19.1% such that significant consequences could be prevented. The research has justified the practicality of these risk analyses for drill and blast tunnelling sites. Also, recommendations are provided for the contractors and workers targeting continuous improvement of safety provisions at tunnelling sites.
Asymptomatic bacteriuria in pregnancy
Authors: Sivalingarajah R. , Balasingham B. , Camilas J.  C.
Published: May 2023

Asymptomatic bacteriuria (ASB) is diagnosed by the presence of a 10*5 colony-forming units (CFU) in the urine without any urinary symptoms. It commonly occurs in pregnancy with the incidence ranging from 2-10%. It poses a risk of progressing into pyelonephritis in pregnancy. Adverse fetal outcomes include preterm labor, neonatal sepsis, intrauterine growth restriction (IUGR) and neonatal death. Anatomical and physiological changes during pregnancy make pregnant women more vulnerable to ASB and subsequently symptomatic UTI. E coli is the commonest organism involved in ASB, followed by Klebsilla and Enterobactericiae. Evidence suggests that importance of routine screening for ASB in early pregnancy to avoid adverse fetomaternal outcomes. Reduced adverse outcomes were noted with prompt antibiotic treatment for ASB compared to untreated pregnant women with ASB. Urine culture remains as the gold standard method to diagnose ASB in pregnancy. Using urine culture as a routine screening method in Sri Lanka is limited due to financial restrictions.

Published: May 2023

Background: Percent fluid overload greater than 5% is associated with increased mortality. The appropriate time for fluid deresuscitation depends on the patient's radiological and clinical findings. This study aimed to assess the applicability of percent fluid overload calculations for evaluating the need for fluid deresuscitation in critically ill patients. Methods: This was a single-center, prospective, observational study of critically ill adult patients requiring intravenous fluid administration. The study's primary outcome was median percent fluid accumulation on the day of fluid deresuscitation or intensive care unit (ICU) discharge, whichever came first. Results: A total of 388 patients was screened between August 1, 2021, and April 30, 2022. Of these, 100 with a mean age of 59.8±16.2 years were included for analysis. The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was 15.4±8.0. Sixty-one patients (61.0%) required fluid deresuscitation during their ICU stay, while 39 (39.0%) did not. Median percent fluid accumulation on the day of deresuscitation or ICU discharge was 4.5% (interquartile range [IQR], 1.7%–9.1%) and 5.2% (IQR, 2.9%–7.7%) in patients requiring deresuscitation and those who did not, respectively. Hospital mortality occurred in 25 (40.9%) of patients with deresuscitation and six (15.3%) patients who did not require it (P=0.007). Conclusions: The percent fluid accumulation on the day of fluid deresuscitation or ICU discharge was not statistically different between patients who required fluid deresuscitation and those who did not. A larger sample size is needed to confirm these findings.
Reflections on Waterscape Aesthetics in Chinese Tradition
Authors: Wang Keping
Published: May 2023

Philosophy is akin to poetry due to their respective endeavour to express the ultimate good sense which we term civilization. This can be exemplified through the Chinese vision of waterscapes which is found running through Chinese philosophy and poetry alike. As observed in Chinese tradition, the Daoist water allegory is referred to “the supreme good”. It can be further explicated with reference to the Confucian appreciation of “huge waterscapes” in terms of moral symbolism. All this permeates through the poetic depictions of waterscapes in the beautiful, majestic, and musical categories from an aesthetic perspective. Such depictions bear philosophical, moral, and aesthetic values altogether as a result of their underlying linkage with “the ultimate good sense”, and therefore have played an important role in human life from past to present. They are often employed as aesthetic objects as they delight the sight, hearing, mind and spirit. Moreover, they are utilized to revive the sense of Being and homeliness in closer contact with the nature in which we reside.
Open Letter to President Xi Jinping on the Climate Crisis
Authors: Parkes Graham
Published: May 2023

Although climate models predict that global heating will prove more devastating for China than for many other countries, and economic models have shown that a transition to a low-carbon economy would strengthen China in the long run, the Chinese leadership has failed to reduce fossil fuel consumption enough to avoid extremes of weather that are devastating the country. Not long after becoming president, Xi Jinping announced a project to ground “socialism with Chinese characteristics” in selected ideas from ancient Chinese philosophy and culture, promoting the agenda through quotations in his speeches from the Chinese classics, and especially Confucian and Daoist thought. These ideas turn out to be perfectly suited for a ‘reframing’ of worldviews that is required for thinking more productively about the climate crisis and developing political measures for dealing with it effectively.
However, the Chinese leadership has failed to live up to its inspiring words, and has instead reverted to aggressive and repressive policies that are more in line with Chinese Legalism and Stalinism than with the Confucian, Daoist, and Marxist ideas that Xi Jinping has advocated. This has dealt a severe blow to China’s standing in the world and caused a huge loss of ‘soft power’ accumulated by previous regimes. With the United States in a shambles, the way is open for China to follow through on its promotion of traditional Chinese philosophy and take the lead, for the sake of the long-term well-being of its own people, in tackling the climate crisis—and thereby gain the greatest soft power triumph in history.
Masayuki TANIMOTO and R. Bin WONG, editors: Public Goods Provision in the Early Modern Economy: Comparative Perspectives from Japan, China, and Europe
Authors: Wu Jiarui
Published: May 2023

Previous studies regarding the emergence and development of social systems have often been based on the study of European nations, which largely ignores the fact that other nations also underwent the process in patterns that are either similar or strikingly different from the European one. Contemporary researchers have identified this flaw and thus sought to address it by studying the emergence and development of social systems in non-European nations rather than assuming that the European model is the standard. It is in line with this new school of thought that Bin Wong and Masayuki Tanimoto explore social development in Japan and compare it with Europe. In their book Public Goods Provision in the Early Modern Economy: Comparative Perspectives from Japan, China, and Europe, the authors provide readers with a general overview of the systems for public goods provision in early modern Japan, while also offering comparison examples from Europe, primarily from Prussia.
