An Analysis on Chinese EFL Learners’ Understanding of “Direct Object/Subject” Garden Path Sentences
Authors: Bao Yue , Zhang Yi
Published: May 2023

The current study probes into the comprehension of “DO/S” GP sentences by Chinese EFL learners with different language proficiencies. 70 questionnaires are obtained. The results show that 60% triggering condition is not reached in high language proficiency group and no GP ambiguity is found, whereas the GP ambiguity is found and eliminated by low-proficiency group. And the level of language proficiency influences the emergence of GD phenomenon (x2=12.570, p=.000<.05). The Q&A test reveals the residual of the initial misunderstanding among learners. Although the 60% triggering condition is not reached, we find that the comprehension ability differs significantly between the two groups based on the scores of their answers (p=.004<.05). It can be safely concluded that the L2 proficiency will affect learners’ comprehension of “DO/S” GP sentences. The higher L2 proficiency learners gain, the more likely they may eliminate the ambiguation of GP sentences and there will be less residual of misunderstanding.
Kallawaya, Inc. ̶ the making of the Kallawaya (1532-2008)
Authors: Fischer Eva
Published: May 2023

The Kallawaya are a Bolivian ethnic group well known for ritualism and naturopathy. This paper explores the ‘making’ of the Kallawaya as a polity emerging, modifying, and adapting over time according to its political and economic needs, at the intersection of local conditions and of global developments. The case of the Kallawaya shows how processes of ethnicization unfold through the interplay of primordialist and of instrumentalist logics. An important vehicle for ethnicization is resilience as expressed by the cultural memory.

Authors: Barbadekar Dr. Ashwinee
Published: May 2023

Abstract: A borewell rescue robot which can rescue a child trapped inside bore well is presented in this work. Borewell accidents involving children falling into uncovered bore holes are unfortunately all too common and can have tragic consequences. In this work we designed a gripper which shall perform operations like holding child smoothly and lifting it up without causing any injuries to child. It comprises of 4 DOF which makes it more unique than other grippers. The gripper is designed by keeping various factors in mind like as holding capacity, flexibility. The bevel gear supporting gripper consists of 32 teeths, for more reliability and flexibility. The Micro Servos used has payload capacity of 1gm/cm. The robots could be equipped with cameras and sensors to detect the child's location and condition, as well as provide them with food, water, and other necessities to keep them alive until rescue teams arrive. The use of robots in borewell rescue operations could not only help to save lives but could also reduce the risk to human rescuers who often must undertake these operations in precarious conditions.

Resume Parser Analysis Using Machine Learning and Natural Language Processing
Authors: Rasal Pratham
Published: May 2023

Abstract: With the rise of online job application processes, submitting a resume has become easier than ever before. As a result, a larger number of individuals are impacted by this change. Many organizations still accept resumes by mail, which can cause challenges for their human resources departments. Sorting through a large number of applications to find the most suitable candidates can be a time-consuming process for these agencies. Job applicants submit resumes in a wide range of formats, including various fonts, font sizes, colors, and other design elements. Human resources departments are responsible for reviewing each application and selecting the most qualified candidate for the job. My suggestion is to incorporate natural language processing techniques into the project's parser to assist the human resources department or recruiting manager in analyzing the information provided in resumes. This approach can involve using keyword matching and other natural language processing methods to identify the most suitable candidates and obtain the most effective resumes. By doing so, the organization can improve its recruitment process and identify the best candidates for the job.
Design and Analysis of Fixed Brake Caliper using Additive Manufacturing
Authors: Kulkarni Gautam
Published: May 2023

Abstract: The brake caliper's function is to channel the mechanical force generated by the driver's mechanical action on the brake master cylinder—pressurized fluid—into an outward force that may be directed to the car's brake rotors. The effectiveness of the brakes plays a significant role in a vehicle's performance, and the design of the caliper may be improved by taking into account elements like the bleeding port, the brake pads, and the fluid flow path. As two-wheeler calipers are often used in automobiles, the entire system must be dismantled, bled, and then reassembled involved halves. Custom calipers have been employed by commercial automakers to cut back on the extra work involved in developing and producing RH and LH calipers. This project aims of this project are to create, evaluate, and maybe construct a front brake caliper prototype for the Formula Student cars. The desired outcome would be for the brake caliper to outperform all of the "firms" and set us apart from the other competing teams. Additive manufacturing is a new and rapidly developing manufacturing method. The current manufacturing processes for brake calipers separate components assembler.

The Turmoil in the Moscow State at the Beginning of the XVII Century and Its Influence on the Transformation of the Foundations and Principles of Russian Statehood (Political Science Aspect)
Authors: Omelchenko Nikolay A.
Published: May 2023

The article gives the author’s interpretation of the nature and degree of influence of the events of the Time of Turmoil at the beginning of the XVII century in Russia on the evolution of the foundations and principles of Russian statehood. The author of the article notes that this problem, which is important for understanding the history of Russian statehood, has not yet received proper coverage and the necessary scientific study. Agreeing with the opinion of researchers who assess the events of the Turmoil as the first deep state crisis in the development of the country, the author of the article draws attention to the fact that modern publications do not take into account the fact that in many respects it was the tragedy of the Turmoil that predetermined many new phenomena in the state and public life of Russia, which ensured the country’s exit from the Turmoil and the restoration of state order. On the one hand, the masses, under the influence of the events of the Turmoil, began to assimilate new ideas about the relationship between the government and society that were not peculiar to them before, linking the concept of the state with the “land”, with the concept of “common benefit”. On the other hand, the Russian political elite was also forced to revise the previous methods of government and build their relations with citizens on the basis of taking into account public interests, common “zemstvo” benefits. The article substantiates the methodologically important position that it is from the events of the Turmoil that it is possible to start the formation of a new understanding of the state and state power in Russian society in their modern meaning. The author of the article leads to the idea that it was these changes in the consciousness of the masses and the behavior of the elite that became decisive for the country’s exit from the Turmoil, at the same time drawing a parallel with the Byzantine model of power, the stability of which in times of crisis was also explained by the presence of a unique state structure that connected the rigid monarchical vertical and the horizontal of developed self-government.

Aim: The study aimed to assess the relative filtration rates of an indigenous freshwater mussel, Lamellidens marginalis and an indigenous freshwater snail, Pila globosa, and their suitability for incorporation into freshwater integrated multi-trophic aquaculture (FIMTA) systems. Methodology: An indoor experimental trial was conducted in a wet laboratory (temperature: 30.5 ± 0.5, light intensity: 2000 lux, light cycle: L: D: 12hr: 12hr). The trial was performed in glass aquaria in triplicate filled with algae rich water to assess their filtration rate. Simultaneously, the impacts of these two molluscs on inorganic nitrogen and phosphorus were evaluated. Results: L. marginalis exhibited filtration rates of 934.7± 0.07 cells min-1 mussel-1 and 13.79 ± 0.04 cells g-1 min-1) against 261.8 ± 10.15 cells min-1 snail-1 and 9.74±0.15 cells g-1 min-1 for P globosa. Similarly, the mussel also exhibited markedly higher turbidity and chlorophyll clearance capacity (p<0.05) in comparison to snail, especially during initial 6-12 hr when initial concentrations of algal population, turbidity and Chl-a were high. Notably, the oxygen consumption and ammonia excretion rates were greater for snail than mussel after 24hr and at the end of the experiment. Interpretation: The results provide quantitative information on the filtration capacity of two indigenous freshwater molluscs that have considerable local food as well as economic value and would pave the way for their utilization as ecological engineers, especially organic extractive in freshwater integrated multi-trophic aquaculture (FIMTA) system. It is concluded from the study that L. marginalis was more efficient in extracting almost four times algal cells than, P. globosa.

Methodology: The abundance and distribution of subsurface microfibers in four locations of Tuticorin inshore waters were estimated by filtering subsurface waters using a 250µm mesh epineuston net. The non-biodegradable macrolitter on the seabed at three locations of Thoothukudi was estimated by swept area method. Results: Among the four selected stations, a higher quantity of microfibres was observed in the subsurface waters at 5m depth close to nearshore areas, with the highest mean numerical abundance of 3.13±0.3 nos.m l-1. The annual difference in the subsurface microfibre abundance varied significantly between stations (p<0.05). Plastics were the most dominant litter constituents on the sea beds among three stations. A significant seasonal variation (p<0.05) with maximum mean total macrolitter abundance was noticed on the seabed at Kayalpattinam (45.81± 9.3 kg km-2). The estimated mean macrolitter abundance at all the stations was higher than the reported national average of 10.95±3.05 kg km-2. Interpretation: This study revealed variations in the abundance and distribution of microfibers and macrolitters in the selected areas of Tuticorin. The study emphasises the role of land and marine-based anthropogenic activities in the plastic pollution of this region.

Aim: To isolate an endophytic bacterial community associated with bryophytes, which were collected from various locations in Mount Abu, Rajasthan, and to characterise their morphological, biochemical, and biofilm development properties. Methodology: Different bryophytes were selected from various regions of Mount Abu, Rajasthan. On an R2A agar plate, colonies with various morphologies were isolated. Biofilm development of bacterial isolates was done on a glass surface and visualised through scaning electron microscopy. Biochemical test, such as indole test, catalase test, urease test, MR and VP tests, citrate utilization test, gelatine and nitrate test, etc., were determined as per Berge’s Manual of Determinative Bacteriology for characterization of endophytic bacteria. Salkowski's technique was also used for estimating IAA production by endophytic bacteria. Results: The results confirmed that isolates belonged to two phyla groups, Firmicutes and γ-proteobacteria with predomination of Firmicutes. Scanning electron microscopy showed that among all the isolates, rod-shaped bacteria dominated. The metabolic properties of endophytic bacteria showed that most bacterial isolates metabolised glucose, maltose and sucrose, however, only few bacterial endophytes metabolized lactose. Some isolates produced IAA growth hormones, which were analysed through Salkowski's technique. Interpretation: The findings indicate that bryophytes have associated bacterial diversity. The morphological and biochemical characterization of bacteria revealed that they are members of the Firmicutes and γ-proteobacteria phyla. SEM confirmed that bacterial isolates can form biofilm on glass surfaces and produce a distinct amount of IAA in a tryptophan-supplemented medium, essential for the growth and development of bryophytes.

Aim: To evaluate the soils of Malli-1 micro watershed situated in the North-Eastern Dry Zone (Zone-2) of Karnataka for sustainable crop development. Methodology: Eight soil profiles covering all soil types occurred in the study area were selected and studied for their detailed morphological, physical and chemical properties using standard soil testing procedures. Results: Soils of Malli-1 microwatershed varied from clay to clay loam in texture, moderately to strongly alkaline in reaction with low salt content and low to medium in per cent organic carbon content. Calcium and magnesium were the prevailing cations followed by sodium and potassium. Soils were classified upto the series level as per revisions in Soil Taxonomy by utilizing soil characteristics. Majority of soils in study area represents the Vertisols, Inceptisols and Entisols order. Interpretation: These results indicate that soils were less fertile due to deficit in soil nutrients. Recommended doses of organic bio-fertilizer and inorganic fertilizer should be practiced for reclamation of soil status.

Aim: Characterization and spatial mapping of irrigation water quality of Hathin block, District Palwal, Haryana. Methodology: In order to assess the ground water quality for irrigation suitability and their effect on soil chemical properties, 68 ground water samples were collected, and analyzed for pH, EC, anions (CO32-, HCO3-, Cl-, SO42- and NO3-) and cations (Ca2+, Mg2+, Na+ and K+). Water quality indices [(Sodium adsorption ratio (SAR) and residual sodium carbonate (RSC)] were also computed. Results: The pH and EC of water samples ranged from 6.69-8.35 and 0.77 -11.99 dSm-1 with mean value of 7.48 and 4.21 dSm-1, respectively. The cations and anions followed the order: Na+> Mg2+> Ca2+> K+, and Cl- > SO42-> HCO3−> CO32−>NO3−. RSC and SAR ranged from Nil - 5.40 me l-1 and 5.64 - 19.98 (mmol l-1)1/2, respectively. According to All India Coordinated Research Project (AICRP) classification, out of total water samples, 17.6 % were found as good, 22.1 % as marginal saline, 4.4 % as saline, 48.5 % as high SAR saline, and 7.4 % as higher alkali. Interpretation: The soluble ions were found higher under higher saline conditions as compared to the locations had good quality irrigation water, which altered soil nutrient status. In order to mitigate the negative impacts of such water, it is advised that brackish or saline groundwater be used to irrigate field crops by diluting it with canal (good quality) water.
