Authors: TAKU T , SANTRA A , BARIK S , MANDAL D K , DAS S K
Published: December 2022

Nutritional evaluation as tree fodder as well as a rumen manipulator of six multipurpose Himalayan forest tree leaves, viz. Kadam (Anthocephalus cadamba), Kaew (Costus speciosus), Karoi (Albizia procera), Bakful (Sasbania grandiflora), Gamar (Gmelina arborea), and Barhar (Artocarpus lakoocha), were evaluated by in vitro gas production test. The mean content of OM, CP, EE, T-CHO, NDF, ADF, cellulose and lignin of these tested tree leaves were 91.4, 14.6, 3.9, 72.8, 42.7, 31.2, 19.8, and 11.1% on DM basis, respectively. The gas production per g digested dry matter varied from 111.1 ml/g DDM/24h in Bakful (Sasbania grandiflora) to 612.3 ml/g DDM/24h in Barhar (Artocarpus lakoocha) tree leaves while methane production per gram digested dry matter varied from 14.7 ml/g DDM/24h in Kadam (Anthocephalus cadamba) to 102.2 ml/g DDM/24h in Bahar (Artocarpus lakoocha) tree leaves. TVFA and propionate production were higher due to inclusion of Karoi (Albizia procera) tree leaves in the incubation media. However, lowest NH3-N concentration and rumen protozoal population were observed due to incubation of Kadam (Anthocephalus cadamba) tree leave. Similarly, activity of polysaccharide degrading enzyme like carboxymethyl cellulase, xylanase and Î²-glucoidase enzymes were lower due to incubation of Kadam (Anthocephalus cadamba) in comparison to other tested tree leaves. However, activity of amylase enzyme was similar among all the tested tree leaves. Highest IVTDMD (52.3%) was observed for the Karoi (Albizia procera) tree leaves followed by Kaew (Costus speciosus) (47.9%) and Kadam (Anthocephalus cadamba) (43.8%) tree leaves. Similarly, TDN and ME content were also highest for Karoi (Albizia procera) tree leaves. The results indicated that among the tested tree leaves, Karoi (Albizia procera) was best tree fodder for feeding to the animals and Kadam (Anthocephalus cadamba) can be used as rumen manipulator to reduce ruminal methanogenesis and protozoal population for improving animal productivity.

Published: December 2022

To find out the trend in production and consumption of livestock products in Meghalaya and explore the means and ways to plan an efficient and proper market accordingly, the study was conducted using both secondary and primary sources of data. The clear cut objectives were to examine and analyse the growth in livestock population in Meghalaya and to analyse the consumption pattern of livestock products. Compound annual growth rates (CAGRs) in livestock population during nine inter-census periods were positive for cattle, pig and poultry; negative growth rates were observed during few periods in case of buffalo, sheep, goat and horses and ponies; sheep population mostly showed negative growth rate as sheep is reared mainly for meat purpose and the meat is not as popular as beef or pork. Milk, egg, mutton and chicken are still luxury items in the rural region; egg and chicken are items of luxury in urban regions whereas fish consumption was relatively income inelastic in both rural and urban regions. Thrust can be made in the processing of milk into different milk products and popularization of sheep rearing focusing on rearing for wool rather than meat.

Published: December 2022

We investigated the chameleon screening mechanism in Brans-Dicke scalar-tensor theory. We preserved the fundamental premise of the typical chameleon mechanism, which is that the field is huge in high-density environments but essentially free in low-density environments like the solar system. We discovered thin-shell solutions for a static and spherical symmetric body and demonstrated the model’s applicability to local data.

Authors: Syahbana Abas , Zen Freddy Permana , Dwiputra Donny
Published: December 2022

In this paper, entangled K-meson model and decoherence phenomenon in thesystem is studied. Using Lindblad equation, dynamical equation of entangled K-meson systemthat interacts with the environment is obtained. We find that non-Hermitian Hamiltonian ofthe system makes completely positive and trace-preserving map (CPT-map) on the space ofdensity matrix does not satisfy trace preserving properties. We also find that purity of densitymatrix can be less than 1=d which does not satisfy the property of purity. From the dynamicalequation, parameters related to the decoherence of the system, decoherence parameter (λ) andeffective decoherence parameter (ζ), are determined. Using Standard Least-Squares method,we obtain ζ = 0; 13±0; 865. This result is in accordance with references result that use effectivevariance method, ζ = 0; 13±+0 -0;;16 15. We show that ζ = 0; 13±+0 -0;;16 15 corresponds with referencesresult, λ = (1; 84±+2 -2;;50 17) × 10-12 MeV. The value of both parameters are close to zero relativeto ζ = 1 or λ ! 1. It means that the interaction between system and environment doesnot affect the system significantly. Therefore, quantum properties in the system related to theentanglement of the strangeness is preserved.
Trans-stilbene based spherical mesoporous organosilica material for loading and release of hydrophobic curcumin
Authors: GÖK Yaşar , ARLI Osman Tayyar , GÖK Halil Zeki
Published: December 2022

In this study, a new mesoporous organosilica carrier system was synthesized in which hydrophobic trans-stilbene is placed on the walls of the drug delivery system. In this way, it is aimed to increase the interaction between hydrophobic curcumin and the silica surface and to load more curcumin into the drug delivery system. Trans-stilbene based mesoporous organosilica (TSMON) material was prepared in the reaction of (E)-1,2-bis(4-(3-(triethoxysilyl)propyl)phenyl)ethylene (1) with tetraethyl orthosilicate in the presence of triblock copolymer cetyltrimethylammonium bromide as a template in NaOH solution. Characterization of synthesized TSMON was done by FT-IR, XRD, BET, SEM and TGA analyses. Curcumin loading into the drug delivery system TSMON was carried out by mixing curcumin and TSMON in the dark for 24 hours. After the measurements made in the UV-Vis spectrophotometer, entrapment efficiency and loading capacity for TSMON were calculated as 22% and 18.2%, respectively. Next, the time dependent release of curcumin from Cur@TSMON at physiological and endosomal pH was studied. After 5 days of UV-Vis measurements, the percentage of curcumin release from Cur@TSMON was around 1% at pH = 5 and 7.4. The low release percentage obtained indicates a strong interaction between TSMON and curcumin penetrating the pores of the TSMON. This strong interaction allowed the drug delivery system TSMON to carry 99% of the payload without leaking at pH = 5 and 7.4 without pore capping agents.

Euclidean distance degree of zero-set of two polynomials
Authors: Pham Thu-Thuy
Published: December 2022

In this note, we recall the study of the Euclidean distance degree of an algebraic set X which is the zero-point set of a polynomial (see [BSW]). Specifically, consider a hypersurface  defined by a general polynomial  f  with its support and contains the origin i.e 0  support of f. In the paper [BSW], the authors study about the Euclidean distance degree (EDD) and found that the EDD of this hypersurface is approximately by the mixed volume (MV) of some Newton polytopes.
The main purpose of this note is to study the case that the manifold is defined by two polynomials . We show that the Euclidean distance degree is equal to the solution of the Lagrange multiplier equation. Furthermore, we also find out that the EDD of this variety is not greater than the mixed volume of Newton polytopes of the associated Lagrange multiplier equations.

Published: December 2022

This paper deals with approximate Pareto efficient solutions of a nonsmooth fractional interval-valued multiobjective optimization. We first introduce some types of approximate Pareto efficient solutions of the considered problem by considering the lower-upper interval order relation. Then we apply some advanced tools of variational analysis and generalized differentiation to establish necessary optimality conditions of Karush–Kuhn–Tucker (KKT)-type for these solutions.
Forgotten and Invisible Laborers: Domestic Workers in Singapore and Taiwan
Authors: Ng Lynn
Published: December 2022

This paper is about legal yet unjust systems of domestic servitude; the oppressive circumstances that ‘foreign maids’ the world over face as unappreciated, unrecognized, and undervalued workers in the invisible domestic space. Regardless of political culture and regime - liberal democracies to authoritarian governance – ‘maids’ are excluded from normal labor standards. The author explains and discusses the legal blind spots, loopholes, and oversight of labor clauses for foreign domestic workers (FDWs) in the East Asian states of Singapore and Taiwan. This paper aims to spark critical conversations about the public/private divide, also the feasibility of enacting home-based legislation for private household workers. It uses the reviewed literature – relevant research studies, government websites, and news sources – and interview findings to advance its main claims. Between May 2021 and July 2022, the author conducted online semi-structured interviews on WhatsApp/Zoom with 61 people who were directly or indirectly involved in eldercare provision: FDWs, domestic employers, recruitment agency managers, unpaid family caregivers, and NGO workers. The author’s analysis shows that FDWs, called ‘maids’ in the local parlance, face a myriad of shocking abuses by sending/receiving governments, unscrupulous recruitment agencies, and host employers who view them as private property (owned) rather than human beings with needs. This paper argues that FDWs deserve to be respected and included in formal labor laws like the rest of the workforce, to better safeguard their physical safety, mental wellbeing, and personal dignity

Authors: Rodrigues Maria Angélica A. dos Santos , Azevedo Livia Maria Gabrielli de
Published: December 2022

Este artigo contextualiza historicamente o papel institucional da governança e do planejamento no cenário metropolitano e, após três anos de vigência da Lei Federal nº 13.089/15 (Estatuto da Metrópole), descreve as primeiras iniciativas adotadas nas regiões metropolitanas do país e especificamente as da Bahia, como a criação da Entidade Metropolitana da Região Metropolitana de Salvador (EMRMS), as experiências em torno da retomada do planejamento metropolitano no estado e na elaboração do Plano de Desenvolvimento Integrado da Região Metropolitana de Salvador (PDUI-RMS). Pretende chamar a atenção para a importância da entidade de governança que consubstancia a possibilidade de os entes metropolitanos e do Estado realizarem o planejamento e a execução das funções públicas de interesse comum. Sem a prevalência de poderes, constitui-se na busca de uma convivência mais positiva, em que os agentes participativos sejam chamados a definir e assumir uma matriz de responsabilidades complementares. É imperiosa a sua estruturação administrativa e o seu fortalecimento institucional. A elaboração do PDUI-RMS, no âmbito da EMRMS, traz o desafio maior de uma ação coletiva através de uma rede institucional com participação social. Nesse contexto, a elaboração do PDUI pode se constituir num instrumento para a construção das novas estratégias, diretrizes de desenvolvimento e de governança para a RMS que contemple suas contradições e a consolidação do território metropolitano para o século XXI.

Early diagnosis and treatment of lung cancer in TB patients remains a challenge. The presence of active TB or post-TB changes is a factor, which impedes timely detection of lung cancer. Differential diagnosis estimates the history of pulmonary TB or surgical interventions as TB/post-TB changes in the lungs and underestimates the possibility of tumor development. This may result in delayed diagnosis of lung cancer and worsen treatment prognosis. The article represents clinical observations of the development of lung cancer after successful treatment of advanced pulmonary TB. According to our experience, the emergence of new infiltrative changes in the operated lung without bacterioexcretion and atypical clinical course of the disease should alert and make continue diagnostic search. In such cases, resection samples should be obtained for histological, cytological, and microbiological studies to allow rapid differential diagnosis between TB and lung cancer in the operated lung.

The article describes a clinical observation of timely detected and treated female genital tuberculosis (FGTB) in an immunocompetent woman with tubal-peritoneal infertility before enrollment in the in vitro fertilization (IVF) programme. We have outlined diagnostic features of the disease, its association with the history of pulmonary TB, primary methods of examination, and treatment principles in FGTB. The examination included controlled simulation of ovulation, sonography, laparoscopy, hysteroscopy, pathomorphological studies, X-ray and computed tomography of the chest, endometrial biopsy. We also performed Ziehl–Neelsen microscopy of sputum, endometrium; luminescent microscopy; inoculation of endometrium, menstrual blood, and sputum onto solid and liquid nutrient media. We described successful pregnancy after IVF in a patient with tubal-peritoneal infertility due to FGTB after TB treatment. We concluded how important was to consider TB as a possible cause of bilateral fallopian tube blockage. Success and safety of IVF was preconditioned by timely detection and treatment of TB in the fallopian tubes, the endometrium, and the abdomen, as well as thorough monitoring of the reproductive organs.

Ethanol extracts of Alpinia galanga (L.)Willd. (rhizome), Coscinium fenestratum (Goetgh.) Colebr. (stem), Piper betle Linn. (leave), Piper longum L. (fruit), Zingiber cassumunar Roxb.(rhizome) and chitosan were evaluated for their fungicidal activities in controlling Alternaria leaf spot of Chinese kale, caused by Alternaria brassicicola, under field conditions. The results showed that the application of these plant extracts resulted in reduction of disease severity in a concentration-dependent manner. Among the five plant extracts tested, the extracts of P. betle and C. fenestratum at a concentration of 10,000 ppm displayed potent fungicidal activity in the suppression of disease severity, causing 43% and 41% disease reduction, respectively. The extracts of Z. cassumunar and A. galanga at 10,000 ppm showed moderate effectiveness in controlling the disease, causing 28% and 25% disease reduction, respectively, whereas the extract of P. longum at the same concentration possessed the lowest antifungal activity, reducing the disease severity by less than 20% at the highest dosed tested. The application of chitosan at 2% had a moderate effect; it reduced the disease severity by 30%. However, the application of the systemic fungicide, iprodione, displayed the greatest fungicidal activity in suppression disease severity, causing 65% disease reduction. The results in this study indicated that the P. betle and C. fenestratum may be promising eco-friendly candidates for controlling Alternaria leaf spot disease in Chinese kale production.

Imidacloprid and the fungus Beauveria brongniartii (1x102 to 1x108 conidia/ml) were evaluated against the green peach aphid, Myzus persicae (second instar) and their predator Coccinella undecimpunctata (day-old adults) in tomato plantations in two different climatic Governorates Dakahlia and EL Behira. Using a spray technique to evaluate contact effect and a feeding technique to evaluate oral toxicity. Our results showed that under laboratory conditions, the LC50 values of Imidacloprid and B. brongniartii were 66 ppm and 72 conidia /ml, respectively against M. persicae. Under field conditions, the percentages of infested plants with M. persicae were significantly decreased after treatments with both Imidacloprid and B. brongniartii as compared with the corresponding controls. In El- Esraa Nobaryia (Behira) and El Dakahlia, the weights of tomato yield were 4978± 74.31 kg/feddan (F) and 4597±65.12 Kg/F in Imidacloprid plots treatments. The percentages of yield loss ranged between 24, 49 and 22, 50 in El- Esraa Nobaryia (Behira) and El Dakahlia, respectively. The study showed that C. undecimpunctata exhibit relatively high and reasonable resistance to Imidacloprid and Beauveria brongniartii at their highest lethal concentration for tested prey.

Published: December 2022

This study focuses on empirically investigating the effect of role stress of caregivers on job satisfaction and turnover intention. In order to achieve this research purpose, this study comprehensively reviewed domestic and foreign previous studies on role stress, job satisfaction, and turnover intention. hypotheses and research models were established. The results of this study are as follows. First, it was found that role stress had a negative (-) effect on job satisfaction. It can be seen that the higher the role stress, the lower the job satisfaction. Second, job satisfaction was found to have a negative (-) effect on turnover intention. It can be seen that the higher the job satisfaction, the lower the turnover intention. As a result of the study, it was found that the less role conflict, role ambiguity, and role overload, which are components of role stress, the higher the job satisfaction of caregivers, and the higher the job satisfaction, the lower the turnover intention. Therefore, it is more important than anything else to reduce the role stress of caregivers working in elderly medical welfare facilities and to increase job satisfaction of caregivers. To this end, it is necessary to develop a standard manual that can reduce role conflict, role ambiguity, and role overload of caregivers.

Substrate assemblages of Myxomycetes (Myxogastria) on the bark of living trees and aerial litter in Vietnamese forests
Authors: Fedorova N. A. , Shchepin O. N. , Nguyen Dang Hoi
Published: December 2022

Myxomycete (Myxogastria) are amoeboid protists, usually associated with soil or nearby substrates, as their trophic stages require moist conditions and sufficient number of microorganisms to feed on. However, they are able to inhabit places that have no direct connection with soil. In this paper myxomycete assemblages encountered on bark and aerial liter, a unique substrate of tropical forest, were studied. The material was collected in different years in various vegetation types of 3 national parks, Phia Oac-Phia Den, Bidoup-Nui Ba and Cat Tien, located in distant parts of Vietnam during the last 10 years. Taxonomic diversity was revealed via the experiment using moist chamber cultures. A total of 1009 cultures resulted in 747 records, assigned to 87 morphospecies from 5 orders, 9 families, and 23 genera. Seventy-three species were recorded on the bark of living plants and 45 were found on aerial litter, and the study for each substrate was completed for 74.5 and 72.7 per cent respectively. More than a half of the total number of species was presented by singletons and doubletons. The analysis of indicator species was performed, which confirmed the dominance of specialist species on bark (Cribraria confusa, C. minutissima, and Licea operculata) and aerial litter (Perichaena depressa, P. dictyonema, and P. pedata). Some species, such as Perichaena chrysosperma, demonstrated no specific substrate preference. A typical lignicolous species in temperate regions, Stemonitis fusca, appeared to be abundant on aerial litter, showing a change in substrate preferences, which is common for several myxomycete species in tropics. High-quality photographs, including those obtained with SEM, of 10 indicator morphospecies are provided.

Growth plate extracellular matrix defects and short stature in children
Authors: Saltarelli Maria Alessandra , Quarta Alessia , Chiarelli Francesco
Published: December 2022

Many etiological factors causing short stature have already been identified in humans. In the last few years, the advent of new techniques for the detection of chromosomal and molecular abnormalities has made it possible to better identify patients with genetic causes of growth failure. Some of these factors directly affect the development and growth of the skeleton, since they damage the epiphyseal growth plate, where linear growth occurs, influencing chondrogenesis. In particular, defects in genes involved in the organization and function of the growth plate are responsible for several well-known conditions with short stature. These genes play a pivotal role in various mechanisms involving the extracellular matrix, intracellular signaling, paracrine signaling, endocrine signaling, and epigenetic regulation. In this review, we will discuss the genes involved in extracellular matrix disorders. The identification of genetic defects in linear growth failure is important for clinicians and researchers in order to improve the care of children affected by growth disorders.
Anoxia-Related Biogeochemistry of North Indian Ocean

Complex interactions between microbial communities and geochemical processes drive the major element cycles and control the function of marine sediments as a dynamic reservoir of organic matter. Sulfate reduction is globally the dominant pathway of anaerobic mineralisation and is the main source of sulfide. The effective re-oxidation of this sulfide at the direct or indirect expense of oxygen is a prerequisite for aerobic life on our planet. Although largely hidden beneath the oxic sediment surface, the sulfur cycle is therefore critical for Earth’s redox state. This Geochemical Perspectives begins with a brief primer on the sulfur cycle of marine sediments and a description of my own scientific journey through nearly fifty years of studies of sulfur geochemistry and microbiology. Among the main objectives of these studies were to quantify the main processes of the sulfur cycle and to identify the microbial communities behind them. Radiotracers in combination with chemical analyses have thereby been used extensively for laboratory experiments, supported by diverse molecular microbiological methods. The following sections discuss the main processes of sulfate reduction, sulfide oxidation and disproportionation of the inorganic sulfur intermediates, especially of elemental sulfur and thiosulfate. The experimental approaches used enable the analysis of how environmental factors such as substrate concentration or temperature affect process rates and how concurrent processes of sulfate reduction and sulfide oxidation drive a cryptic sulfur cycle. The chemical energy of sulfide is used by chemolithotrophic bacteria, including fascinating communities of big sulfur bacteria and cable bacteria, and supports their dark CO2 fixation, which produces new microbial biomass. During the burial and aging of marine sediments, the predominant mineralisation processes change through a cascade of redox reactions, and the rate of organic matter degradation drops continuously over many orders of magnitude. The main pathways of anaerobic mineralisation and the age control of the organic matter turnover are discussed. In the deep methanic zone, only a few percent of the entire degradation process remains, which provides a small boost of substrate for sulfate reduction through the process of anaerobic methane oxidation. The stable isotopes of sulfur provide an additional tool to understand these diagenetic processes, whereby the combination of microbial isotope fractionation and open system diagenesis generate a differential diffusion flux of the isotopes. In relation to the organic carbon cycle of the seabed and the contribution of methane, the paper discusses the global sulfur budget and the role of sulfate reduction for organic matter mineralisation in different depth regions of the ocean - from coast to deep sea. The published estimates of these parameters are evaluated and compared. Finally, the paper looks at future perspectives with respect to gaps in our current understanding and the need for further studies.
Possibilities of Implementation of the Ecological and Legal Mechanism of Environmental Protection for the Regulation of Economic Activity in the Coastal Territories of Lake Baikal
Authors: Lesnykh Svetlana Ivanovna
Published: December 2022

In the environmental legislation of the Russian Federation, designed to regulate public relations about nature, the concept of nature protection is a priority. Lake Baikal is a territory with special conditions of use, with unique natural characteristics and a powerful system of ecological and legal regulation of public relations in the field of environmental protection. For effective planning and regulation of economic activity in the coastal territories of Lake Baikal, it is advisable to involve an ecological and legal mechanism for environmental protection, which allows unambiguously determining the priority right to use the territory, relying on environmental legislation and protecting the rights of nature in resolving conflict situations. The use of the legal environmental zoning tool, which significantly enhances the ecological and legal mechanism by means of cartographic visualization, implemented with the involvement of geoinformation systems, allows us to simultaneously display the effect of all regulatory and legal restrictions on a specific area of the territory. This makes it easy to navigate the legislative space manifested on the ground, taking into account the characteristics of the territory, determine the priority right to use the territory and find the optimal permitted option for conducting permitted activities. So, on the example of the Slyudyansky district of the Irkutsk region, a comparison of the categories of legal zoning with maps of real use of resources was carried out, which clearly showed contradictions in real and permitted use. The visual implementation of the ecological and legal mechanism and the possibility of improving environmental management is shown, through the introduction of a mechanism that allows to identify violations in the regulated use of the territory in an operational mode, ensuring safe rational use of natural resources through the search for the optimal use of different areas of the territory.
The Trickster’s Evolution in “Frankenstein in Baghdad” by Ahmed Saadawi
Authors: Vlasova Yuliya
Published: December 2022

The subject of the study is the image of Hadi the Junkman, coined the modern Iraqi writer Ahmed Saadawi in the novel “Frankenstein in Baghdad” (2013). The author is interested how the residents of the Iraqi capital survive under American invention. The author presents the picture of the 2000-s years using the fate of the Baghdadis as an illustration. He describes numerous explosions in Baghdad and the consequences they had on its citizens future. The novelist compares the living conditions of ordinary people of the Batavia quarter and high-ranking government officials. The figure of a junk dealer Hadi al-Atak, who walks around the city in search of antiques and tells entertaining stories unites the people with different background. Being a trickster, a liar, or buffoon, old man has created an imaginary monster that fights against injustice and avenges the innocent people who died in terrorist attacks. The methods of historical and system analysis allow us to prove that in the era of formation change, the role of the trickster is becoming more important and modified. Shuttling between good and evil, the Junkman helps to smooth out conflicts and resolve disputes peacefully. Due to the breakdown of life paradigms, the trickster has a special function: he becomes the leading hero and saves humanity from evil, performing a Christological role. Taking the blame for the crimes of his brainchild “Whatsitsname” (Arab Frankenstein), sacrificing his life, the Hadi the Junkman brings peace and stability to the tired people of Baghdad.

In order to solve the problem of low frequency noise of engine, based on the principle of dual port asymmetric sound absorber, a kind of gradually changing size sound absorbing metasurface is designed to reduce the noise of engine acoustic liner. Firstly, the theoretical analysis model and simulation analysis model of the asymmetric resonance sound absorber are established, the noise reduction mechanism is revealed, and the influencing factors of the noise reduction effect are analyzed. Then an acoustic metasurface acoustic liner is designed based on the asymmetric resonance sound absorber. The noise reduction effect of the acoustic liner is analyzed in depth by using three methods: full model theoretical calculation, equivalent impedance theoretical calculation and COMSOL finite element simulation. Then, the parameters of this structure are optimized, and the influence of flow velocity on the noise reduction effect is considered by using the full model theoretical calculation and equivalent impedance theoretical calculation. The research results show that the acoustic metasurface acoustic liner designed based on asymmetric sound absorber can achieve noise reduction effect of more than 3 dB in a frequency band range from 252 to 692 Hz when the thickness is only 2.5 cm (only 1/54 of the corresponding wavelength of 252 Hz), which provides a new idea for designing engine noise reduction.

For efficient storage and processing of massive data in the information technology era, spintronic device attracts tremendous attention due to its low power consumption and non-volatile feature. Spin source material, which can efficiently generates spin current, is an important constituent of novel spin-orbit torque device. The efficiency of spin current generation in spin source material directly determines the performances of various spintronic devices. In the past two decades, great progress has been made in exploring high-efficient spin source material systems and understanding the relevant physical mechanisms. A wide variety of materials are explored, ranging from traditional heavy metals and semiconductors to topological insulators and two-dimensional (2D) materials. Recently, the material family of transition metal oxides attracts tremendous attention due to its efficient and highly tunable charge-spin conversion intimately related to its emerging novel quantum states and electronic structure. The mechanism of charge-spin conversion generally has two contributions: the bulk spin Hall effect and the spin-momentum locked interface with inversion symmetry breaking. Novel electronic structures such as topological band structures and spin-momentum locked surface states can realize efficient charge-spin conversion. For example, the Weyl points in SrRuO3 and the topological Dirac nodal line in SrIrO3 are predicted to give rise to a large Berry curvature and corresponding spin Hall conductance; the topological surface states can generate spin accumulation due to spin-momentum locking; the Rashba states at the oxide interface such as the 2D electron gas in SrTiO3 and KTaO3 can generate spin current by Rashba-Edelstein effect. Furthermore, the entanglement of various degrees of freedom, including spin, charge, lattice and orbit in transition metal oxides lead to the electronic structure being highly tunable by various methods including gate voltage, substrate constraint, thickness, interface engineering, etc. Therefore, charge-spin conversion in transition metal oxides is of great significance for both modulating of novel electronic structure in fundamental research and exploring its promising potential in future spintronic devices. In this review, we focus on introducing aspects of exotic electronic structures, spin transport mechanism, charge-spin interconversion characterization, efficiency and manipulation in transition metal oxides, and giving a prospect on the future development trend.
