Laser Deposition of High Manganese Iron Alloy for Wear and Corrosion Resistance
No full textThe usage of aluminum alloys for automotive applications has been growing rapidly. Research is being done to incorporate aluminum alloys as a replacement material for automotive components wherever possible. As aluminum itself has poor tribological properties, coatings are being developed to improve these properties. However, these conventional industrial coatings are not suitable to improve properties as they lack compatible materials and feasible manufacturing process. The purpose of this thesis is to develop low cost material with suitable manufacturing process that will improve the wear and corrosion properties of aluminum. The material was iteratively developed from iron manganese (Fe-Mn) alloys which are used extensively in mining applications. Influence of aluminum, chromium and carbon additions were studied in order to improve both corrosion and wear resistance of the alloy. A laser cladding process was utilized to create desired alloys. To study the microstructure and other material properties, the deposited alloys was analyzed and tested for corrosion, wear, hardness, and x-ray diffraction. Wear resistance, corrosion, and hardness of the alloy was found to be superior to that of conventional cast iron and stainless steel.Master of Science in Engineering (MSE)Mechanical Engineering, College of Engineering & Computer ScienceUniversity of Michigan-Dearbornhttps://deepblue.lib.umich.edu/bitstream/2027.42/145458/1/Thesis Report-Update(Sujeet Shinde).pdfDescription of Thesis Report-Update(Sujeet Shinde).pdf : Thesi

Faunal Remains from Girawad (2006-2007), District Rohtak, Haryana
No full textThe Harappan site of Girawad was excavated for a single season in 2006‐07 by excavators from Deccan College, Pune; MD University, Rohtak and Research Institute for Humanity and Nature, Japan to salvage fast‐vanishing archaeological record. This single culture site, circular in plan and 8 ha in area, lies 3 km to the east of the present village of Girawad. Altogether 41 trenches revealed 13 pitdwelling complexes with ceramics similar to Hakra Ware which portrays a regional variation that can roughly be dated to middle of Fourth Millennium BC. The faunal material (n=4671) from this site was analyzed at the Archaeozoology Laboratory at Deccan College, Pune following internationally standardized procedures. This paper throws light on the diverse faunal spectra and the role and contribution of different mammalian and non‐ mammalian species to the human subsistence at Girawad. Methods used include NISP, skeletal representation and a minute study of pre and post depositional bone modifications generated by anthropogenic and other causal agents in the background of their contexts

Distribution:—Hitherto, based on our surveys, the species has been observed only in a couple of localities i.e. near Patanus village and Rawalje village, Raigad District, Maharashtra (Western Ghats), India. Ischaemum dioecum is apparently an extremely rare and narrow endemic species in the genus. Flowering and fruiting:—August to mid September (life cycle of individuals hardly exceeding 20 days). Additional specimen examined:— INDIA. Maharashtra state: Raigad district, near Rawalje village, 24 August 2021, 18°26’36.9”N 73°21’29.0”E, Shahid Nawaz RR-05 (BLAT) [staminate plant specimen, spikelets were removed for the study]. Habitats and ecology:—In complex network of dense roots mingled with seasonally wet thin film of soil at the base of other taller grass species such as: Ischaemum diplopogon Hooker (1896: 129), Heteropogon ritchiei & Dimeria blatteri Bor (1949: 70), on the flank of the river associated with rocky outcrops and on the slope of basalt rocks. The microhabitats are protected from the direct sunlight, wind and precipitation; thus are special with their own specific environmental conditions that include moisture, temperature and light. These factors are regulated by the presence of benefactor species (three mentioned above) from directly influencing I. dioecum therefore contributing positively in survival of this species. In the late October, when monsoon subsides, the resultant heat generated by the basalt rocks, on prolonged exposure to sunlight is immense; eradicating all the annual and transient vegetation cover. In such challenging habitats, plants that are acclimatized rapidly complete their life cycle by bearing seeds. In which I. dioecum has the shortest life cycle, hardly exceeding 20 days! Associated species:— Arundinella pumila Steudel (1854: 114), Heteropogon ritchiei, Ischaemum diplopogon, Dimeria blatteri, Ischaemum barbatum Retzius (1791: 35), I. semisagittatum Roxburgh (1832: 320), Ischaemum sp., Geissaspis sp. Etymology:—The epithet alludes to a dioecious breeding system of the species, where male and female plants are sexually separate individuals. Population and threat:—In the first locality the habitats are encroached and disturbed by tourists visiting Devkund waterfall during monsoon when the individuals are in flowering. The first author has also observed that the shallow shores of the river attract many villagers especially women for washing clothes. However, the second locality is far from the reach, at least for villagers and their livestock. The basalt slopes make the domestic quadrupeds unable to climb and disturb the thin population of Ischaemum dioecum. These basalt habitats, during monsoon, are extremely slippery and difficult to climb upon. At least because of this, there the population of this extremely rare grass is, perhaps, on a small magnitude, protected. However, in this habitats Celosia sp. is very troublesome and exhibits a great possession. It may threat the existence of this species in future. IUCN status:—Based on our field observations, it can be asserted that the population is severely fragmented and confined over the two localities (Figs. 3 & 4) few kilometers apart from each other. The type locality exhibits tourist encroachment and disturbance. The total number of individuals in both the subpopulations is less than 25 in which female plants are relatively higher in numbers as compared to the male counterparts. The observed data suggests 7 male individuals over 18 female individuals. Hitherto, based on the limited surveys, data is not available to discuss declination thus those categories and criteria cannot be assessed. We have not seen Ischaemum dioecum in any other locality except the two given though surveyed the region more or less for almost a month during monsoon. Based on this it is perhaps not too quick to assess the plant as Critically Endangered (CR) under B1 (Extent of occurrence <100 km 2), D (mature individuals <50) of IUCN Red List Categories and Criteria (2019). Notes:—Since, the species is extremely delicate, slender, weak and non-tufted, it demands an additional support from the stilt-roots, that are present up to almost half of the plant height assisting it to stand upright without falling. In some specimens stilt-roots are present till the last node i.e. below the inflorescence, and may measure up to 12 cm high. The staminate and pistillate plants differed quite sufficiently in appearance of the inflorescence that one might easily mistake them for members of different species! The most striking contrast between the two is that the formers are essentially awnless, whilst those of the pistillate plants bear conspicuous awns (Figs. 1 & 2). The features that are common in both plants are such as: solitary habit with stilt-roots; leaves thin-membranous, hispid, long, petioled and acute at the base; ligule membranous; few spikelets up to three or less than three in the spiciform-raceme; 2–4-nerved lower glumes of the sessile spikelets; lower floret absent; upper palea bi-dentate at the apex with an arista from the sinus and pedicelled spikelets absent or reduced to a single glume i.e. half the length of the sessile spikelets. Females in comparison to males are, at least somewhat, easier to search in the field and tend to exist in a relatively higher numbers. Whilst, the male plants are very few and extremely rare in occurrence and challenging to trace; so far, we, during our surveys, found only few male plants in which only two were collected for further study. As compared to the female plants, males are slightly taller, more delicate, bearing thinner leaves and higher number of stilt-roots.Published as part of Landge, Shahid Nawaz & Shinde, Rajendra D., 2022, Ischaemum dioecum (Poaceae: Andropogoneae): the most strangest new species from Northern Western Ghats, Maharashtra, India, pp. 237-255 in Phytotaxa 533 (5) on pages 239-242, DOI: 10.11646/phytotaxa.533.5.1, http://zenodo.org/record/614492

Historiografía feminista con referencia especial de Pandita Ramabai y Tarabai Shinde
No full textIn colonial Maharashtra women tried to converse with themselves and the society through biographies, autobiographies, articles in newspapers, journals and they even wrote books, trying to discuss women\u27s issues that arose from the patriarchal system of society at the time. They criticized social customs and blind faith in religion pertaining women, very intensely. Their writings were theoretical and visionary, and stood out creating a baseline for feminist historiography; here my efforts are to interpret their writings from that point of view. The first part of this paper discusses the efforts of feminist historiography as a whole and the second part is based on the book, "The High Caste Hindu Woman" and "Stri-Purush Tulana" by Pandita Ramabai and Tarabai Shinde respectively.En el Maharashtra colonial, las mujeres intentaron conversar con ellas mismas y con la sociedad a través de biografías, autobiografías, artículos en periódicos, revistas e incluso escribieron libros, tratando de discutir los problemas de las mujeres que surgieron del sistema patriarcal de la sociedad en ese momento. Criticaron muy intensamente las costumbres sociales y la fe ciega en la religión de las mujeres. Sus escritos fueron teóricos y visionarios, y se destacaron creando una línea de base para la historiografía feminista; Aquí mis esfuerzos son para interpretar sus escritos desde ese punto de vista. La primera parte de este documento discute los esfuerzos de la historiografía feminista en su conjunto y la segunda parte se basa en el libro "La mujer hindú de la casta alta" y "Stri-Purush Tulana" de Pandita Ramabai y Tarabai Shinde, respectivamente
