Unfolding Industrial Output: A Study of India’s Formal Manufacturing Sector
Authors: Choudhry Sonam
Published: July 2023

Investigation of economic development and growth has been at the forefront of economic research (Denison 1962; Barro 1996). The idea of focusing on the industrial sector to drive economic growth has been a global phenomenon. The process of economic growth has been supplemented with several structural changes that an economy goes through. The mainstream literature predicts that the opening up of the economy increases the exports of commodities based on the economy’s comparative advantage. One of the principal questions that the paper attempts is to examine whether the openness of the Indian economy resulted in the expansion of the share of export-oriented industries and the reduction of import-competing industries' share in manufacturing output. The analysis uses rich granular-level data on the Indian formal manufacturing sector. Furthermore, the analysis of structural changes requires looking not only at the growth rate over a particular period but also at the cumulative increase in growth of the sector according to different activities which may be labour or capital-intensive. The paper using cluster-based analysis decomposes manufacturing growth into labour and capital-intensive activities and brings out important aspects on how the manufacturing output is been produced. The pattern of capital intensity of Indian manufacturing firms shows that firms have systematically witnessed an increase in capital intensity. Factors such as incentives in the form of subsidies, and reduction in tariffs on capital goods made access easier to adopt advanced technology. Also in today’s globalised world, the pressure on domestic firms to remain competitive both in the external and domestic markets created grounds for adopting the latest (more capital-intensive) techniques.
Advancing an African Theory of Rights and Its Potential for Quality Citizenship
Authors: Ugwuanyi Lawrence Ogbo
Published: July 2023

Given the numerous instances of crisis of citizenship and state belonging which disproportionately obtain in African states in comparison with other continents of the world it becomes urgent to provide positions that address the problem. This works sets out to do this by engaging the problem of rights in Africa and looking at how it affects quality citizenship. This is because the primary goal of the state is to protect rights and properties. The work will do this by engaging the nature of rights administered in the African states. It will provide a theoretical account of how a wrong idea of rights constitutes part of the problem and why the quality of rights administered in African states should be held to be the source of the problem. It will then proceed to address the problem by formulating a theory of rights anchored on an African worldview which harbours the potential to address the problem. The theory will defend the view that rights can only be found cogent and worthy to compel loyalty to its demands if it is rooted in the values and ideals of people and that an idea of rights that is endogenous to African people will be more cogent, valuable and reliable to citizenship ethics in Africa and compel loyalty to the African state. The work applies the methods of expository analysis and intuitive deduction to arrive at its positons and postulations.

Western Ideological State Apparatuses and Native American Culture in Erdrich’s LaRose
Authors: Maqbool Tabassum , Rakha Aqsa Allah
Published: July 2023

This research sheds light on Western use of educational Ideological State Apparatuses (ISA) as an important weapon to eradicate Native American culture. Although there have been huge research on Native American Culture and Euro-American oppression of Native Americans, very small is known about the ideological method of European oppression. The picture that appears from Louise Erdrich’s LaRose is that for Europeans, education is a tool to enlighten the natives. However, for the natives, education is a process of transforming their culture into Western ideology promoting Western socio-cultural norms. Ideological oppression is more adverse than subdued oppression.  This study analyses Louis Erdrich’s Larose through Althusser’s theory of ISA which means that people are controlled firstly by ideology, then by constraint. Europeans used both suppression and ideology to obliterate their culture by which they could assimilate them, and there would be a minor risk of resistance. As a result, Europeans have tried to eradicate the religion and culture of Native Americans through education to establish their own culture and religion. Louise Eldritch uncovers the dark side of the educational civilization process, which this research shall analyze through Althusser’s theory of ISA.

Authors: Ojonta Obed I.
Published: July 2023

The purpose of this study is to examine how delayed payment obligation influences household purchase decision in Nigeria. Unlike the large of existing studies, this study used binary regression model estimation and draws a dataset of 2019 General Household Survey with sample size of 2911 household for the analysis. The stylized facts from the dataset revealed more share of rural household than their counterparts in urban household. Interestingly, the results show that delayed payment obligation is positive and significantly influence purchase decision of household in Nigeria. But when the household is disaggregated into rural and urban household, the result shows that some household that barrowed from friends and family and household that reduced food consumption expenditure have positive and significant influence on purchase decision in both rural and urban household while household that received assistance from friends and family has positive and significant influence on purchase decision by rural household. This study recommends delayed payment obligation for important factor to drive purchase decision by household. This could be achieved through policy formulation that will promote delayed payment obligation.

Published: July 2023

Nigeria is a developing nation with a population of over 200 million. Of this aggregate, approximately 106 million are aged 18 years and above. Of this adult population, 70 million live in rural areas, and many do not have adequate access to relevant financial products and services. The proportion of individuals and firms that use or have access to financial services can be referred to as financially inclusive. This study analyzes the impact of financial inclusion and domestic investment on Nigeria’s financial development. Multiple regression analysis was employed in this study which spanned over the period, 1982-2021. The empirical results reveal that financial inclusion and domestic investment have positive impacts on financial development; however, domestic investment has a more significant impact to a larger extent. The study recommended that policies should be directed towards creating a more inclusive financial system to improve the current level of financial inclusion to achieve better financial development in Nigeria. This study concludes that governments should formulate policies that boost financial inclusion and investment to deepen the level of financial development in the economy.

Authors: Bowen Mark , Jones Tim , Nedas Ben , Waring Rosemary
Published: July 2023

Manipulation of the intestinal microbiome is an emerging area of research, especially in hind-gut fermenters such as the horse. The aim of this study was to determine whether fecal pH can provide a simple and cost-effective tool to document changes in the intestinal metabolome and microbiome following supplementation of feed with an enzyme rich malt extract (ERME). Fecal pH was determined weekly in triplicate using a commercial soil pH meter in 72 Thoroughbred racehorses in training before and during supplementation with ERME (300mls per day divided into two feeds) alongside their regular feeding schedule. No control group was included. Fecal pH increased over the 4 weeks of treatment from 6.20 (6.15-6.24) to 6.40 (6.38-6.44; P<0.0001). Changes were not observed at one-week intervals but were apparent after 2 weeks There was a significant increase in the proportion of horses with a ‘normal’ pH at the end of the study (55%) compared to the start of the study (11%; p<0.001). These data support the further validation of the use of fecal pH in large scale microbiome/metabolome studies in the horse, although comparisons with these outcomes are now warranted.

Published: July 2023

In order to solve the problem of environmental pollution caused by a large number of discarded hickory husks in Lin'an, and to make them a clean energy source that can be recycled, in this paper,using crushed hickory husks as raw material, single factor test was carried out on a hydraulic plunger forming machine with different moisture content and length-diameter ratio of forming sleeve.The change of axial pressure and radial force in the forming sleeve is measured by the sensor, and the microstructure of the biomass moulding fuel briquette was observed by stereomicroscope. The results showed that the hickory husks could be compressed and formed at room temperature. When the moisture content of the hickory husks is 14% and the length-diameter ratio of the forming sleeve is 4.5, the forming quality is the best, and the relaxation density of the formed briquette is up to 0.98g /cm3. When the moisture` content is the same, the forming pressure increases with the increase of the length-diameter ratio of the forming sleeve. When the length-diameter ratio of molding sleeve is the same, the molding pressure increases first and then decreases with the increase of water content.
Influence of Pvd Deposition Mode on the Quality and Integrity of CrAlN Thin Films: A Study of Magnetron Sputtering Processes on Stationary and Rotating Substrates
Authors: TLILI Brahim , NASSER Mohamed , GUIZENI Hichem , MONTAGNE Alex
Published: July 2023

The development and qualification of CrAlN coatings deposited by DC magnetron sputtering offer new industrial solutions to increase the lifecycle of material forming tools (machining and shaping). This study focuses on the selection and optimization of deposition modes for CrAlN layers to be deposited on a 90CrMoV8 tool steel substrate. The adopted methodology aims to optimize the deposition conditions to meet the customer's requirement of a CrAlN coating thickness of approximately 2-3 µm for use in a hot forming process. Different polarizations using two Al and Cr targets, with both stationary and rotating substrate modes during deposition, were tested and evaluated. Characterizations of the CrAlN coating layers (microhardness, residual stress, structures) and performance in service (wear, friction, adhesion, corrosion) were chosen as selection criteria for a particular coating mode. The aluminum content plays a crucial role in the tribological and mechanical behavior of CrAlN layers. Corrosion resistance is more sensitive to the aluminum content for the stationary deposition mode. As a result, the rotating mode provides higher adhesion (+100%) and less wear (-60%) compared to the stationary mode. Therefore, depending on the likely performance in service, either a stationary or rotating mode could be applied for coating the functional surfaces of hot forming tools.
Pathogenic Speciation and Phylogenicity: Mechanisms of Antimicrobial Resistance in Food Quality
Authors: Victor Okpashi
Published: July 2023

Our ability to cure common diseases is still in danger due to the creation and spread of bacteria and fungi that are resistant to drugs and has developed new resistance mechanisms. The increasing global expansion of multi- and pan-resistant bacteria commonly referred to as "superbugs," which cause diseases that cannot be treated with current antimicrobial medications like antibiotics, is particularly concerning. Indirect and direct risks to public health are posed by microorganisms that are resistant to antibiotics in food. Food can get contaminated via cross-contamination, intentionally introducing resistance genes during food preparation, and antibiotic-resistant bacteria in food. Consuming unprocessed or unpreserved food products increases the danger of transferring antimicrobial resistance to people and other animals. Stressed cells in food can have an impact on food quality, safety, and security. They can also contribute to the development of resistance and afterwards spread it to unintended organisms in the food chain. These reviews look at a variety of topics to address the question of how antimicrobial resistance mechanisms work. The various types of bacteria that make up infections are examined, as well as the usage of antimicrobial agents and the requirement for alternative antimicrobial agents that will discourage the use of synthetic antimicrobial agents. Additionally, specific details are provided regarding the uniqueness, interdependence, and phylogenicity of organisms as well as their interactions with various ecological media. Thus, it is clear why it is important to work with food producers and handlers to stop the spread of pathogenic organisms.

Kondisi pembangunan dan perkembangan perumahan serta kawasan permukiman yang pesat, tidak sedikit masyarakat yang tinggal di kawasan permukiman yang termasuk ke dalam kawasan rawan bencana. Hal ini memiliki risiko tinggi dikarenakan kondisi tempat tinggal mereka yang tidak aman dari risiko terjadinya bencana yang dapat terjadi secara tiba - tiba. Untuk melakukan antisipasi terhadap kemungkinan terdampak bencana, maka masyarakat perlu untuk direlokasi ke lokasi yang lebih aman. Oleh karena itu perlunya penelitian untuk mengidentifikasi lahan yang memiliki potensi sebagai lokasi relokasi perumahan bagi masyarakat yang tinggal di kawasan rawan bencana. Metode penelitian yang digunakan adalah kuantitatif. Data penelitian yang dikumpulkan adalah data primer dan sekunder. Hasil pemetaan drone dan hasil penelitian dapat disimpulkan di Kabupaten Sleman yang masih mempunyai sisa lahan kosong antara lain Huntap Gondang 2, Huntap Pagerjurang, Huntap Plosokerep, Huntap Gondang 3, Huntap Dongkelsari, dan Huntap Kuwang. Kabupaten Bantul di wilayah Kalurahan Wukirsari dan Kalurahan Selopamioro, potensi lahan relokasi di wilayah tersebut dengan luasan sekitar 7.368 m2 dan 2.334 m2. Kabupaten Gunungkidul dan Kabupaten Kulonprogo mempunyai karakteristik bencana bersifat spot oleh sebab itu penanganan pola lahan relokasinya cenderung relokasi mandiri dan tidak terpadu. Sehingga diwilayah Kabupaten Gunungkidul dan Kabupaten Kulonprogo belum mempunyai lahan relokasi khusus.

Dunia proyek konstruksi adalah bidang usaha yang sangat kompleks, rumit dan memiliki berbagai macam rIsiko. Fungsi manajemen merupakan kunci utama keberhasilan pengelolaan suatu proyek. Selain itu untuk mencapai keberhasilan suatu proyek dibutuhkan kinerja dan kekompakkan setiap unsur pelaksana proyek guna mencapai tujuan yang diharapkan. Suatu proyek dapat dinyatakan berhasil apabila proyek tersebut memenuhi syarat tercapainya sasaran proyek yaitu berupa tepat biaya, tepat mutu, dan tepat waktu. Metode yang digunakan penelitian ini berupa konsep nilai hasil mengkaji kecenderungan varian jadwal dan varian biaya pada suatu periode selama proyek berlangsung. Berdasarkan hasil evaluasi data sekunder pada Proyek Pembangunan Jalan Tol Semarang-Solo Ruas Bawen-Solo Seksi 2, maka dapat ditarik kesimpulan sebagai jawaban dari tujuan penelitian. Antara lain Total SV (positive) mengalami percepatan dengan nilai indikator 7.06%. Sedangkan total SV (negative) menunjukkan indikator perlambatan dengan nilai -5.63%. Hasil indikator perhitungan nilai SV yang menunjukkan positive dan negative yang berarti percepatan dan perlambatan proyek dalam setiap bulannya. Perkiraan waktu akhir proyek/ SPI to go = 1.00, sehingga dapat disimpulkan bahwa proyek tidak terlambat / tepat waktu. Dan didapatkan perkiraan biaya akhir proyek / CPI to go = 2.36, sehingga dapat disimpulkan proyek tidak mengalami kerugian.

Based on its quality, paving blocks are used in the construction sector and an alternative choice for surface pavement layers. Several other advantages are concrete bricks (paving blocks) better than other pavements and are economical in maintenance, artistic in terms of the exterior of a building, do not require heavy equipment to work/install, and can be mass-produced. This study aims to compare the compressive strength of paving blocks using a compression test and hammer test and to determine the quality of paving blocks. In this study there are 9 objects, 3 different shapes of paving blocks consist of 3 pieces of each form.  The form of paving blocks used are brick paving blocks, hexagons and worms (univape). Based on the test results, there is a difference in the compressive strength value of the compression test and the hammer test, where the compression test compressive strength value is greater than the hammer test compressive strength value. The results of the compressive strength test showed that the paving blocks were in the category of quality B paving blocks.

A woman who is in pregnancy from conception to birth is called a pregnant woman. Pregnant women can be at risk of anemia due to the impact of folic acid deficiency. Alternative innovations in healthy snack products for pregnant women include pineapple cakes, which are innovated with broccoli which is rich in folic acid and mango podang. The type of method of this research is experiments using organoleptic tests where researchers measure the level of preference for processed products from broccoli flour 3 treatments P1 (100% wheat flour: 0% broccoli flour), P2 (96.5% wheat flour: 3 broccoli flour, 5%) and P3 (93% wheat flour, 7% broccoli flour).The results showed that the highest acceptability of this product to color was P1 (97%), the highest aroma acceptability was P1 (97%), the highest texture acceptability was P1 (95%), and the highest taste acceptability was P1 (98%). This is because the P1 dough has not been mixed with broccoli flour so that in terms of color, aroma, texture and taste it has superior results, but the difference in the percentage of acceptability with P2 and P3 is not much different.
Molecular basis for the enzymatic inactivity of class III glutaredoxins on standard glutathionylated substrates

Glutaredoxins (GRXs) are small proteins that interact with the atypical tripeptide glutathione (GSH), a redox active metabolite that forms a disulfide (GSSG) upon oxidation. GRXs encoding variants of a CPYC motif at a conserved active site act as GSH-dependent thiol-disulfide oxidoreductases (class I). GRXs with a CGFS site (class II) bind GSH in a way that is non-permissive for thiol-disulfide oxidoreductase reactions and favours transient iron-sulfur cluster binding. The biochemical functions of CCxC/S-type (class III) GRXs, which are found only in land plants, have remained largely unexplored. In this study, we characterized the in vitro properties of one of the Arabidopsis thaliana class III GRXs, namely ROXY9. In contrast to class I GRX AtGRXC2, ROXY9 was inactive as a reductase on the small substrate bis(2-hydroxyethyl)disulfide (HEDS) and as an oxidase on the redox-sensitive fluorescent protein roGFP2. Redox titrations with different GSH/GSSG ratios revealed formation of a disulfide bond (S2) between the first and the last cysteine of the CCLC motif at -220 to -230 mV. Glutathionylation (SG) at the first reactive cysteine was not observed. In contrast, AtGRXC2 and another class I GRX, HsGRX1, were oxidized to roughly equal amounts of GRX-SG and GRX-S2 over a wide range of GSH/GSSG ratios. The different reactivity of ROXY9 towards GSSG as compared to class I GRXs is most likely due to subtle differences in the GSH binding mode and explains why ROXY9 does not function as a GSH-dependent oxidoreductase on standard substrates. This feature might have evolved to avoid overlapping functions with class I GRXs in planta.

Gene expression analysis enhances proper cancer subtyping, a better understanding of the molecular characteristics of cancer, and strategies for precision medicine. However, salivary gland cancer (SGC) subtyping remains largely unexplored because of its rarity and diverse histopathological and immunological characteristics. This study aimed to determine whether the histological origin and immunological characteristics of SGC subtypes are intrinsic tumor immunity factors. We performed immune profiling of 94 RNA-seq of SGC tissues and found that the SGCs that originated from the excretory duct (ED), such as the salivary duct and mucoepidermoid carcinomas, exhibit higher immunity than those from the intercalated duct (ID), such as the adenoid cystic and myoepithelial carcinomas, based on the computationally predicted immune score (p < 0.001), immune cell enrichment in the tumor immune microenvironment (TIME) (p < 0.001), T-cell receptor diversity (p < 0.001), and expression of signal I (major histocompatibility complex, MHC, p < 0.001) and signal II (co-stimulatory, p < 0.001 and co-inhibitory, p < 0.001) genes. Further analysis revealed that tolerogenic dendritic cell-induced dysfunctional T-cell populations and T-cell exclusion in the TIME are the major immune evasive mechanisms of the ED-and ID-derived SGCs, respectively.
