Published: October 2022

For sustainable crop production and maintenance of soil health, conservation agriculture (CA) practices provides an opportunity for improving soil structure and physical health, nutrient and water use efficiency, soil organic carbon and mitigation of greenhouse gases emission from agriculture. CA is primarily based on four crop management practices such as minimum soil disturbance or no-tillage; permanent or semi-permanent retention of crop residue; crop rotation and control traffic. Different CA management practices affect crop yield as well as soil properties. CA makes necessary modifications in different soil hydro-physical properties, viz. increase in soil water infiltration, reduction in water runoff and soil loss, and reduction in evaporation loss. No tillage (NT), residue retention and crop rotation combined effect the soil organic carbon concentration. Different crop rotations and residue retentions and crops with different rooting depths used in CA practices have proved to reduce the compaction constraints.CA can help to mitigate GHG emissions, viz methane (CH4) and nitrous oxide (N2O) from agriculture by improving soil C sequestration, enhancing soil quality, nitrogen and water use efficiencies, and decreasing fuel consumption. But effect of CA and conventional agricultural practices of porosity and pore size distribution is very much limited. When CA is practiced for six to ten years there is improvement in soil structure, porosity and pore size distribution, macro-micro faunal activity, and organic matter content..The soil under ZT has the lowest porosity as compared to conventional management practices. The highest porosity and the maximum connected pores are frequently seen in conventionally tilled soil. In this paper, an attempt has been made to review the variation of porosity and pore size distribution and other soil physical properties under conservation agricultural practices.

Published: October 2022

To find out the effect of temperature, osmotic stress, light, pH, salt stress, burial depth, mulching and flooding duration on seed germination and seedling emergence of Melilotus indicus, laboratory and screen house experiments were conducted at CCSHAU, Hisar, during rabi seasons of 2015-16 and 2016-17. All the experiments were conducted in a completely randomized design with each treatment having four replications. Based on research results, it was observed that the optimum temperature range for the germination of M. indicus was 15-30oC day temperature and 10-20oC night temperature. It was more sensitive to moisture stress, as its seed germination decreased from 95% to 38% with increasing moisture stress (from 0 to -1.2 MPa), whereas it was less sensitive to salt stress: as more than 50% seed germination occurred at 125 mM NaCl salt concentration. The optimum pH for its seed germination (90%) was neutral (pH 7). It was non-photoblastic in nature, as dark and light period had no significant effect on its seed germination. The optimum burial depth for higher seedling emergence was 1 cm (>90%), but its emergence decreased as burial depth increased further. The seedling emergence was reduced by the application of rice straw as mulch, though a high amount (4 to 10 t/ha) of straw was required to suppress its emergence significantly. Continuous flooding for different durations significantly reduced the seedling emergence of M. indicus over no-flooding condition, and was not able to emerge after 32 days of continuous flooding. The information gained from this study would help in developing effective weed management strategy against M. indicus.

Authors: SINGH SATISH KUMAR , PATRA ABHIK
Published: October 2022

Limited information is available regarding status of available Ni in Indian soil and almost no literatures available on Ni deficient soils. Hence, the present investigation was undertaken to generate database on Ni content in soil and identifying the potential Ni deficit areas. Plant available Ni in different districts soils was assessed by analyzing 526 surface soil samples from Varanasi, 684 from Mirzapur, 523 from Sant Ravidas Nagar and 558 from Chandauli district. The soil samples were analysed for soil reaction (pH), EC, organic carbon and DTPA extractable Ni. All the blocks of Varanasi were high in Ni and its content ranged from 0.03–20.88 mg kg-1. In Mirzapur district, overall 7.16% soil samples were Ni deficit, however at block level, highest deficiency was observed in Sikhar (31.67%) followed by Kon (27.78%) and Majhawa (24.32%). All the blocks of Sant Ravidas Nagar were high in nutrient index rating with variation in Ni content from 0.01–3.31 mg kg-1. Among the four districts, lowest number of Ni deficient soils (1.79 %) were found in Chandauli district with high nutrient index rating. While Mirzapur district had highest Ni deficit soil (7.16%) followed by Sant Ravidas Nagar (4.02%), however, potential threat of Ni deficiency was the highest in Sant Ravidas Nagar (22%) followed by Mirzapur (19%).

Les « Guerres d’Indépendance » italiennes au temps de « Firenze Capitale », 1864-1870 : conquérir Venise, aller à Rome ?
Authors: Guillaume Nicolas
Published: October 2022

La convention entre la France et l’Italie signée le 15 septembre 1864 a provoqué, dans la capitale Turinoise, de violents tumultes et une répression sanglante. Malgré les titres de La Nazione du 21 septembre 1864 annonçant que Florence « accepterait la garde du grand diadème pour le restituer le jour venu où cesserait l’attente de l’Italie sur le chemin de Rome », l’annonce du transfert de la capitale ne soulève pas d’enthousiasme particulier dans la capitale toscane. Dès 1862, Garibaldi, avec le soutien plus ou moins officiel du gouvernement Rattazzi, va prêcher « l’Évangile de la Sainte Carabine », qui doit permettre au royaume de conquérir les terres non encore rattachées à la mère patrie. La Vénétie est la première étape. L’ennemi Autrichien est cru faible, et l’alliance avec la Prusse doit faire de la guerre de 1866 une formalité. Venise sera italienne, mais quelle en seront les conséquences politiques et sociales ? Aller à Rome. Faire de la Ville Eternelle la capitale « naturelle » du Royaume d’Italie. Dès la proclamation du Royaume d’Italie, cette ambition est affichée. Mais cette ambition suppose une double confrontation, d’une part avec le pouvoir temporel du Souverain Pontife, adversaire militairement faible, mais fort de son influence religieuse et diplomatique, et d’autre part avec les nations garantes de la sécurité et de l’intégrité des États Pontificaux, et en premier lieu, l’Empire Français de Napoléon III.
Impact of Internet Financial Reporting on Stock Returns and Trading Volume of Banking Stocks
Authors: Rahmisyari Rahmisyari
Published: October 2022

This study studies and determines the impact of financial reporting on the Internet on stock returns and trading volume. This study is quantitative—a retraction of research ideas backed by previous investigations employing the same variables and Signal theory. Internet Financial Reporting, Stock Returns, and Trading Volume are research variables. The population for this study consists of 43 banking companies listed on the Indonesia Stock Exchange for the period 2021. This study used a purposive sampling method to obtain a total sample size of 29 banks. Secondary data in financial statements are processed and utilized Using Eviews 12, the analytical strategy comprises descriptive statistical analysis and a panel data regression test. The results indicate that Internet Financial Reporting has a positive but negligible impact on the stock returns and trading volume of Indonesia Stock Exchange-listed banking companies. Internet Financial Reporting has not been a factor in determining whether investors are happy with the stock return data. The minimal influence of Internet Financial Reporting on Stock Returns is due to the inability of the company's Internet Financial Reporting value to offer investors complete information about stock returns before making investment decisions in banking companies. This indicates that Internet Financial Reporting has not become a factor in determining whether investors are satisfied with the information they receive regarding Stock Trading Volume. The negligible impact of Internet Financial Reporting on Stock Trading Volume is due to the inability of the company's Internet Financial Reporting value to offer investors accurate information regarding Stock Trading Volume before making investment decisions in banking firms.

OS RITOS DO VODÚN SAKPATÁ
Authors: Martins Rodrigo Nogueira
Published: October 2022

Esta comunicação pretende dar continuidade a um levantamento sobre os ritos relacionados ao Vodún Sakpatá praticados no Brasil e como estes ritos se relacionam com o momento pandêmico pelo qual a humanidade fora acometida recentemente. Com vistas a dar continuidade sobre a compreensão da ritualística dessa divindade presente nos panteões Fon e Yorubá no Brasil, busca-se analisar os ritos dedicados ao Vodún Sakpatá e algumas de suas facetas: Ṣoponná, Ọbalùàiyé, Ọmọlu e Jagun, para que seja possível interpretar os cultos praticados a essa divindade em solo tupiniquim. A metodologia ocorrerá através de revisão bibliográfica, apoiada em um estudo antropológico através de entrevistas com sacerdotes do Candomblé escolhidos aleatoriamente, conforme interesse e disponibilidade de cada um, no intuito de justificar o fato do Vodún Sakpatá ser reconhecido como divindade ligada às epidemias. Possivelmente, para compreender o culto Fon, será necessário seguir de maneira perpendicular ao culto Yorubá, visando à compreensão mais abrangente acerca do entendimento dessa divindade. Esta comunicação conseguiu determinar dois ritos praticados pelos adeptos do Candomblé, sendo um deles de origem Fon, o Andeyì e outro de origem Yorubá, o Olugbajé.

A formação continuada de professores para o uso pedagógico de tecnologias digitais (TD) é sempre um entrave para a inovação e aprimoramento do processo educativo. Tal formação pode se beneficiar do uso de TD, quando essas permitem, por um lado, alicerçar uma comunidade de prática reflexiva e por outro, propor processos de inovação nos espaços educacionais. Para tanto, é importante que o professor se insira em uma rede de prática na qual se sinta compreendido, orientado e apoiado por profissionais mais experientes. Nesse sentido, foi criada uma proposta de formação continuada para professores iniciantes de Matemática. Essa visou a contribuir para a integração das TD ao contexto docente dos professores participantes da formação. Uma rede social na Internet foi criada para alicerçar e ampliar as interações, e permitir a emergência de uma comunidade de prática. No presente artigo é discutido o uso de redes sociais na Internet e a constituição de comunidades de prática na formação de professores. Descreve-se também, a proposta de formação, os caminhos metodológicos da pesquisa e a análise preliminar da formação. Finalizando, são tecidas algumas considerações sobre a formação destacando que a mesma influenciou as práticas docentes dos professores participantes.

Tem-se percebido que a Informática tem rodeado a vida de nossos jovens. Fazê-los afastar-se dela na sala de aula não faz sentido. Porém, a realidade em escolas de alguns municípios de nosso país é a existência de laboratórios de informática que ficam fechados na maioria do tempo. No município de Rio Tinto, um dos fatores que levava a essa situação era a falta de experiência dos professores com o computador, algo que o projeto em que se insere este trabalho tentou mudar. Neste artigo é descrita a experiência de alunos de Licenciatura em Computação e Sistemas de Informação na formação tecnológica de professores do município de Rio Tinto no uso de computadores em suas aulas, incluindo os principais desafios encontrados e lições aprendidas.

Reflexões sobre a importância das políticas públicas e possibilidades diversas de inovar e propor formas de aproveitar o potencial das TIC – Tecnologias de Informação e Comunicação – para a melhoria dos sistemas educacionais. Propomos que, em sua formulação, os governos devem evitar formas de apropriação elitizadas, desconexas das realidades e desafios brasileiros, tanto no campo das TIC quanto nos pedagógicos e sociais. A convergência informática, comunicações digitais e educação apontam para uma ruptura nos processos de disseminação e de apropriação do saber, cujos efeitos já começam a ser percebidos nesse início de século. É necessário rever a ação pública: ao invés do Estado prover, que ele aja a partir de demandas específicas de cada contexto cultural e escolar local.

Investigating the Impact of Educational Space Design in Fostering Social Distancing: A Case Study of the University of Technology Buildings, Iraq
Authors: M. Hameed Al-Delfi Ahmed , S. Salman Abdullah
Published: October 2022

In the light of the ongoing outbreak of epidemics, the Iraqi government ordered the temporary closure of university buildings and explicit compliance with social distancing, fearing increased infection rates among the large numbers of students. This closure, and the fear of infection, acted as an obstacle for users of educational spaces. To overcome this challenge, the study aimed to investigate the impact of educational space design on the effectiveness of social distancing to reduce the spread of epidemics. The shape, area, and furniture arrangement pattern were determined in the study of educational spaces design as a spatial configuration through the level of wayfinding and permeability. To better understand the relationship between the design of the current educational spaces and the effectiveness of social distancing, this study used a visual survey, field visits, and a quantitative method using a space syntax analysis. And the analysis was carried out on various models of educational spaces design in three elected samples of the buildings of the Technological University Baghdad, Iraq. The analysis values were represented in quantitative tables to illustrate the values of the space syntax attributes and charts showing measures of permeability and wayfinding in all the analysed models. The study results show an impact and a close relationship between the elements of educational space design as a spatial composition and the effectiveness of social distancing. This relationship is formed by the effect of the shape, space, and furniture arrangement pattern in changing the values of spatial space relationships. Furthermore, permeability and wayfinding as spatial characteristics depend on those relationships and control users’ circulation within the educational space, which is essential in determining the effectiveness of social distancing.
A Hybrid Phishing Detection System Using Deep Learning-based URL and Content Analysis
Authors: Korkmaz Mehmet , Kocyigit Emre , Sahingoz Ozgur Koray , Diri Banu
Published: October 2022

Phishing attacks are one of the most preferred types of attacks for cybercriminals, who can easily contact a large number of victims through the use of social networks, particularly through email messages. To protect end users, most of the security mechanisms control Uniform Resource Locator (URL) addresses because of their simplicity of implementation and execution speed. However, due to sophisticated attackers, this mechanism can miss some phishing attacks and has a relatively high false positive rate. In this research, a hybrid technique is proposed that uses not only URL features, but also content-based features as the second level of detection mechanism, thus improving the accuracy of the detection system while also minimizing the number of false positives. Additionally, most phishing detection algorithms use datasets that contain easily differentiated data pieces, either phishing or legitimate. However, in order to implement a more secure protection mechanism, we aimed to collect a larger and high-risk dataset. The proposed approaches were tested on this High-Risk URL and Content-Based Phishing Detection Dataset that only contains suspicious websites from PhishTank. According to experimental studies, an accuracy rate of 98.37 percent was achieved on a more realistic dataset for phishing detection.

The Chapter discusses the turbine characteristics to design low-power rating generators. The low-power machine results in small wind turbines, hence distribution of power generators have attracted a growing interest from the demand, for remote and rural electrification. In renewable energy generation the design of the generator from the wind turbine is the most challenging part of the design. The generator specifications have been obtained from wind turbine models such as torque, speed and power. Based on these specifications the design of the generator with rating of 1 kW has been achieved. The turbine characteristics have been studied and various parameters of the designed machine are analyzed through analytical model and finite element analysis.
Categories and Management of Functional Food
Authors: Rana Anvi
Published: October 2022

Functional foods are any whole, fortified, enhanced, or improved foods that provide health benefits beyond the availability of fundamental components when consumed in effective amounts as part of a varied diet regularly (e.g., minerals and vitamins). Based on the type of evidence, this review segregates a range of functional foods. Furthermore, not even all foods labeled as functional foods on the market today are backed up by enough data to substantiate such claims. In the food and nutrition sciences, functional foods are presently one of the most thoroughly researched and encouraged fields. This topic evaluates the complex nature of trying to define functional foods, and also the categorizations of food products introduced to the market as functional, legislation of functional foods, science-based supporting evidence and development of functional ingredients investigation, and a statement to registered dietitians and dieticians specialists on how to keep up to date on nutritional and functional investigation and its interpretation to buyers.
External Flow Separation

Published: October 2022

The flow transit from laminar to turbulent over the surface due to adverse pressure gradient, that the region in between the laminar separation and turbulent reattachment is called Laminar separation bubble. It experiences on the many engineering devices as well as controls the aerodynamic and heat transfer characteristics. The way of transition formation differs based on geometry, flow configuration and method of transition initiations by a wide range of possible background disturbance as free stream turbulence, pressure gradient, acoustic noise, wall roughness and obstructions, periodic unsteady disturbance so on. This chapter discusses about the flow transition on airfoil and nozzle in general and focuses more on the transition process in the free shear layer of separation bubbles, free stream turbulence, and identification of separation point with the help of the CFD method.
Wind Power Fluctuation Compensation by Variable-Speed Pumped Storage Plant in a Grid Integrated System
Authors: Teshager Bitew Girmaw , Han Minxiao
Published: October 2022

Wind power technology is the fastest-growing technology for electrical energy production due to its potential characteristics. However, due to its randomness, it has an unnecessary impact on the operation and stability of the grid system. For example, the problem of power grid frequency fluctuation is more obvious. Fluctuations in frequency, in turn, can even affect the breakdown of power systems. To minimize these problems, a droop vector control strategy applied to variable-speed pumped storage (VSPS) systems can be implemented. This method should be used as a wind power fluctuation compensation solution in the wind farm grid-connected system. This chapter introduces the droop-fed direct power control strategy in a VSPS-wind farm-grid-connected system. The modeling of the system is based on the phasor model technique. The spectrum analysis method is used in the VSPS system to determine the dynamic performance of the power grid under wind power fluctuation compensation and emergencies and is verified on the MATLAB/Simulink platform. The results show that the spectrum analysis method is effective for determining the fluctuation and stability requirements of wind power in large power grids. The VSPS control strategy in the wind farm grid-connected integrated system achieves good power flow regulation and stable grid frequency, and the deviation is within an acceptable range.
Effect of Agricultural Pesticides and Land Use Intensification on Amphibian Larval Development
Authors: Patricia Camacho-Rozo Claudia , Antonio Camacho-Reyes Jairo
Published: October 2022

The increase in human population had to increase the demand for vital resources, including food, generating intensive and extractive exploitation, and impacting natural ecosystems and biodiversity. Land degradation of ecosystems is a serious and widespread problem in the world. The expansion of the agricultural frontier is by direct or indirect human-induced processes, expressed as long-term reduction or loss of biodiversity. The expansion and industrialization of agriculture had been negatively affected by soil fertility, the climate, biogeochemical cycles, bodies of water, and loss of biodiversity on different spatiotemporal scales. Intensive agriculture, in the form of monocultures, is subjected to strict pest controls for the use of highly toxic agrochemicals. Pesticides are used in monocultures by spraying aqueous dilutions. Knowing the toxic effect of pesticides and agrochemicals on amphibians is very important. These animals have special ecophysiological conditions because they have biphasic life cycles composed of an embryonic and larval aquatic development stage and the adult stage in humid terrestrial environments. For these reasons, the amphibians have been observed with increased mortality rates, reduced prey availability, and affected growth rates.

This study aimed at determining ecosystem services and conservation dynamics of three protected forests in Nigeria. Using simple sampling technique, 24 plots with 25 m2 were established in these protected forests to facilitate data collection. A total of 370 individual trees per hectare, disproportionately distributed between 53 different species in 25 families, were encountered in Omo biosphere reserve (BR) while 381 stems in 63 species in 24 families in strict nature reserve (SNR) and Okomu national park (NP) recorded 352 individual stems, 59 species, and 25 families. The three protected forests had high tree species diversity index (Shannon-Wiener diversity index of 3.19 for Omo BR, 3.90 for Akure SNR, and 3.45 for Okomu NP). The values for basal area (36.63, 72.39, and 32.47 m2), volume (427.08, 929.05, and 366.71 m3), above-ground biomass (153.20, 316.73, and 353.92 ton), below-ground biomass (30.64, 63.35, and 190.04 ton), and total carbon stock (70.78, 91.92, and 212.35 ton) for Omo BR, Akure SNR, and Okomu NP, respectively. This study serves as baseline information for management of protected forests in Nigeria and it shows the potential of in-situ conservation for the dynamism of the ecosystem services.

Authors: R. Majithiya Vaishali , D. Gohel Sangeeta
Published: October 2022

The ocean harbors a wide diversity of beneficial fauna offering an enormous resource for novel compounds, and it is classified as the largest remaining reservoir of natural molecules to be evaluated for biological activity. The metabolites obtained from marine invertebrate-associated actinobacteria have different characteristics compared to terrestrial actinobacteria as marine environments are exigent and competitive. Actinobacteria produce a wide range of secondary metabolites, such as enzymes, antibiotics, antioxidative, and cytotoxic compounds. These allelochemicals not only protect the host from other surrounding pelagic microorganisms but also ensure their association with the host. The harnessing of such metabolites from marine actinobacteria assures biotechnological, agricultural, and pharmaceutical applications.

Authors: Peng Jun , Li Xiang
Published: October 2022

This chapter introduces principles, mixing, ignition and combustion and controls processes of oxyfuel combustion which aims to achieve CCS (Carbon Capture and Storage) in IC (Internal Combustion) engines. By replacing air with pure oxygen and using hot and/or cooled EGR as dilutant gas for controlling the combustion process and flame speed, the mixing and combustion process will be explained. Fuel delivery, pre-mixing arrangement between pure oxygen and dilutant gas and their influences on combustion performances will be discussed. HCCI (Homogeneous Charge Compression Ignition), water injection, etc., technologies for enhancing the combustion efficiency will be demonstrated in detail. Finally, the emission characteristics and possible implementation of practical engine operation will be described.

Conventional masonry pieces are simple construction elements used for the building of houses for a long time. Nevertheless, the rapid growth in the demand for social and middle-class housing in developing countries has forced engineers to develop cheaper and new creation processes and systems with better features and qualities. In this sense, to obtain an optimization in masonry pieces, the following must be considered: 1) the material from which it is fabricated and 2) the design (shapes and geometry). As an alternative, in this work, we present the design of interlocked concrete blocks with measures of 12.5 cm wide, 25 cm in height, and 40 cm in length, made with mortar mixtures with high mechanical performance, with which wall sections were built (masonry assemblies of 62.5 × 60 × 12.5 cm and prisms of 62.5 × 40 × 12.5 cm) and then characterized according to standards of the mechanical compression tests. The obtained mechanical compressive strengths were 177.72 kg/cm2 in the unitary masonry pieces, 47.4 kg/cm2 in prisms, and 3.98 kg/cm2 in diagonal compression tests. This type of masonry materials and their assembly procedure can be useful for the manufacture of middle-income and social housing in developing countries.

Published: October 2022

In this manuscript, we investigate and approximate common fixed points of two asymptotically quasi-nonexpansive mappings in CAT(0) spaces. Suppose X is a CAT(0) space and C is a nonempty closed convex subset of X. Let T1,T2:C→C be two asymptotically quasi-nonexpansive mappings, and F=FT1∩FT2≔x∈C:T1x=T2x=x≠∅. Let αn,βn be sequences in [0,1]. If the sequence {xn} is generated iteratively by xn+1=1−αnxn⊕αnT1nyn,yn=1−βnxn⊕βnT2nxn,n≥1 and x1∈C is the initial element of the sequence (A). We prove that {xn} converges strongly to a common fixed point of T1 and T2 if and only if limn→∞dxnF=0. (B). Suppose αn and βn are sequences in ε1−ε forsome ε∈01. If X is uniformly convex and if either T2 or T1 is compact, then {xn} converges strongly to some common fixed point of T1 and T2. Our results extend and improve the related results in the literature. We also give an example in support of our main results.
Regulation of Iron Metabolism in NAFLD/NASH

Published: October 2022

The disturbance of iron metabolism is one of the characteristic features of NAFLD/NASH, and complicated Type2DM, however, as for the mechanisms of the iron deposition observed in the liver of NAFLD/NASH, as well as the correlation between iron metabolism and insulin resistance, the precise pathophysiology and dynamics are still uncertain. In addition, numerous factors might be involved in the pathogenesis of NAFLD/NASH and wide-ranged analysis, as well as multi-targeted treatment, should be considered and challenged for the improvement of the prognosis of NAFLD/NASH. In many NAFLD/NASH cases, a remarkable decline of serum ferritin, as well as the improvement of T2DM, were observed after treatment with Laennec (placenta-derived drug) in accordance with the improvement of the liver dysfunction and histopathological amelioration in the liver. In recent years, it was shown that hepcidin, the principal regulator of iron metabolism exists in human placenta in high concentrations. Then, we examined whether Laennec can restore the pathological background by regulating iron and glucose metabolism in NAFLD/NASH by the action of a “hepcidin inducer”.

The zoonotic potential of foodborne infections, as well as their capacity to secrete toxins that cause a threat to global food safety and nutrition security and is enough to highlight the gravity of the problem. Feeding the estimated world population of 8.4–8.7 billion, 9.4–10.2 billion, and 11 billion people by 2030, 2050, and 2100, respectively, will require significant increases in crop and animal production, which will increase the agricultural use of antibiotics, water and pesticides and fertilisers, and contact between humans, wild and domestic animals, all of which will have implications for the emergence and spread of infectious agents. Hence, Infectious foodborne zoonotic illnesses are spreading at an unprecedented rate over the world. The evidence that animals are carriers of foodborne diseases is examined in this chapter. The processes through which infectious foodborne zoonosis impacts the global food and nutrition security, as well as how human infectious illnesses may affect food production and distribution are synthesised. The need for agricultural and disease management and policy activities, as well as a review of recent research on novel detection and control techniques in addressing the public health threat posed by foodborne Zoonotic illness, is also addressed.
A Primer on Machine Learning Methods for Credit Rating Modeling
Authors: Jiang Yixiao
Published: October 2022

Using machine learning methods, this chapter studies features that are important to predict corporate bond ratings. There is a growing literature of predicting credit ratings via machine learning methods. However, there have been less empirical studies using ensemble methods, which refer to the technique of combining the prediction of multiple classifiers. This chapter compares six machine learning models: ordered logit model (OL), neural network (NN), support vector machine (SVM), bagged decision trees (BDT), random forest (RF), and gradient boosted machines (GBMs). By providing an intuitive description for each employed method, this chapter may also serve as a primer for empirical researchers who want to learn machine learning methods. Moody’s ratings were employed, with data collected from 2001 to 2017. Three broad categories of features, including financial ratios, equity risk, and bond issuer’s cross-ownership relation with the credit rating agencies, were explored in the modeling phase, performed with the data prior to 2016. These models were tested on an evaluation phase, using the most recent data after 2016.

Published: October 2022

Fresh cut fruits and vegetable have gained penetration and popularity since last few years. These fresh cut commodities are in great demand among the consumers as these are ready-to-eat fresh and provide all essential nutrients. The increasing trend in fresh cut produce tends to increase the investment in research and development to address various issues regarding the product supply, refrigeration, packaging technology, processing and shelf life extension. Cutting and peeling causes physical damage to the raw fruit and vegetable that make them more perishable. In these review latest developments that plays the key role in extending the shelf life of the fresh cut are discussed. These technologies help in reducing the microbial load over the fresh cut without much altering the physicochemical properties. Future researches should consider various combined technologies which allow better preservation as well as supplemented with nutritional factors.
