Chapter Nine details my efforts to shift the ethnographic focus of this work onto the plants themselves. I narrate this through a nine-step, “how to” process, one that deploys “thin description” while confronting the problem of “plant blindness” and considering the ideal of “living thinking” as a means of knowing life forms.

This study aimed to optimize medium composition biosurfactant production of achromobacter xylos using response surface quadratic model . Lipoprotein and lipopeptides are used in many industries such as petroleum refining, pharmaceutical, mining, agriculture and bioprocess industries. The point of this assessment was to pull out and portray the biosurfactant passing on restriction of microorganisms from oil corrupted soil and considering their advancement energy at various temperatures and pH. The separation and growth study was directed in MSM medium using lamp fuel oil as sole carbon hotspot for bacterial turn of events. Confined strains were found to be Gram positive bacillus and in general Gram's positive minuscule life forms can convey lipopeptides type biosurfactants. The ideal conditions for achromobacteria xylos growth were discovered to be at pH seven (7) and temperature 30oC. Central composite design (CCD) was utilized to pick the following medium components (MgSO4, NaNO3, CaCl2, (NH4)2SO4, FeSO4, and KH2PO4). Central composite arrangement (CCD) of RSM was utilized to analyze the four parts at five stages, and biosurfactant fixation was evaluated as reaction. Backslide coefficients were directed by backslide examination, and the quadratic model condition was settled. R2 an impetus for bio-surfactant was endeavored to be 0.7527, showing that the quadratic model was basic with the exploratory outcomes. Confirmation of the numerical model was driven by playing out the assessment with the normal overhauled values, and bio-surfactant production was found to be 10.53 g/L. Underwriting of the normal quadratic model was 97.3% exact with the test results facilitated under the ideal conditions. CaCl2, (NH4)2SO4, FeSO4, and KH2PO4 were perceived as successful portions for bio-surfactant delivering 98% of achromobacter xylos microorganism.

Although Jainism has been largely absent from discourses in bioethics and religion, its rich account of life, nonviolence, and contextual ethical response has much to offer the discussion within and beyond the Jain community. In this essay, I explore three possible reasons for this discursive absence, followed by an analysis of medical treatment in the Jain tradition—from rare accommodations in canonical texts to increasing acceptance in the post-canonical period, up to the present. I argue that the nonviolent restraint required by the ideal of ahiṃsā is accompanied by applied tools of carefulness (apramatta) that enable the evolution of medicine. These applied tools are derived from the earliest canonical strata and offer a distinct contribution to current bioethical discourses, demanding a more robust account of: (1) pervasive life forms; (2) desires and motivations; (3) direct and indirect modes of harm; and (4) efforts to reduce harm in one’s given context. I conclude by examining these tools of carefulness briefly in light of contemporary Jain attitudes toward reproductive ethics, such as abortion and in vitro fertilization.

AbstractThe oldest cell-like structures on Earth are preserved in silicified lagoonal, shallow sea or hydrothermal sediments, such as some Archean formations in Western Australia and South Africa. Previous studies concentrated on the search for organic fossils in Archean rocks. Observations of silicified bacteria (as silica minerals) are scarce for both the Precambrian and the Phanerozoic, but reports of mineral bacteria finds, in general, are increasing. The problems associated with the identification of authentic fossil bacteria and, if possible, closer identification of bacteria type can, in part, be overcome by experimental fossilisation studies. These have shown that not all bacteria fossilise in the same way and, indeed, some seem to be very resistent to fossilisation. This paper deals with a transmission electron microscope investigation of the silicification of four species of bacteria commonly found in the environment. The Gram positiveBacillus laterosporusand its spore produced a robust, durable crust upon silicification, whereas the Gram negativePseudomonas fluorescens, Ps. vesicularis, andPs. acidovoranspresented delicately preserved walls. The greater amount of peptidoglycan, containing abundant metal cation binding sites, in the cell wall of the Gram positive bacterium, probably accounts for the difference in the mode of fossilisation. The Gram positive bacteria are, therefore, probably most likely to be preserved in the terrestrial and extraterrestrial rock record.

The technique of labeling of macromolecules with ferritin conjugated antibody has been successfully used for extracellular antigen by means of staining the specimen with conjugate prior to fixation and embedding. However, the ideal method to determine the location of intracellular antigen would be to do the antigen-antibody reaction in thin sections. This technique contains inherent problems such as the destruction of antigenic determinants during fixation or embedding and the non-specific attachment of conjugate to the embedding media. Certain embedding media such as polyampholytes (2) or cross-linked bovine serum albumin (3) have been introduced to overcome some of these problems.

The reconstruction of a three-dimensional image of a specimen from a set of electron micrographs reduces, under certain assumptions about the imaging process in the microscope, to the mathematical problem of reconstructing a density distribution from a set of its plane projections.In the absence of noise we can formulate a purely geometrical criterion, which, for a general object, fixes the resolution attainable from a given finite number of views in terms of the size of the object. For simplicity we take the ideal case of projections collected by a series of m equally spaced tilts about a single axis.

Fifteen years ago, Hall described clearly the advantages of the thin section approach to biological x-ray microanalysis, and described clearly the ratio method for quantitive analysis in such preparations. In this now classic paper, he also made it clear that the ideal method of sample preparation would involve only freezing and sectioning at low temperature. Subsequently, Hall and his coworkers, as well as others, have applied themselves to the task of direct x-ray microanalysis of frozen sections. To achieve this goal, different methodological approachs have been developed as different groups sought solutions to a common group of technical problems. This report describes some of these problems and indicates the specific approaches and procedures developed by our group in order to overcome them. We acknowledge that the techniques evolved by our group are quite different from earlier approaches to cryomicrotomy and sample handling, hence the title of our paper. However, such departures from tradition have been based upon our attempt to apply basic physical principles to the processes involved. We feel we have demonstrated that such a break with tradition has valuable consequences.

Polytypism has been studied for a number of years and a wide variety of stacking sequences has been detected and analysed. SiC is the prototype material in this respect; see e.g. Electron microscopy under high resolution conditions when combined with x-ray measurements is a very powerful technique to elucidate the correct stacking sequence or to study polytype transformations and deviations from the ideal stacking sequence.

Two main problems in high resolution electron microscopy are first, the existence of gaps in the transfer function, and then the difficulty to find complex amplitude of the diffracted wawe from registered intensity. The solution of this second problem is in most cases only intended by the realization of several micrographs in different conditions (defocusing distance, illuminating angle, complementary objective apertures…) which can lead to severe problems of contamination or radiation damage for certain specimens.Fraunhofer holography can in principle solve both problems stated above (1,2). The microscope objective is strongly defocused (far-field region) so that the two diffracted beams do not interfere. The ideal transfer function after reconstruction is then unity and the twin image do not overlap on the reconstructed one.We show some applications of the method and results of preliminary tests.Possible application to the study of cavitiesSmall voids (or gas-filled bubbles) created by irradiation in crystalline materials can be observed near the Scherzer focus, but it is then difficult to extract other informations than the approximated size.

The high detection quantum efficiency (DQE) is the main requirement for an imagerecording system used in electron microscopy of radiation-sensitive specimens. An electronic TV system of the type shown in Fig. 1 fulfills these conditions and can be used for either analog or digital image storage and processing [1], Several sources of noise may reduce the DQE, and therefore a careful selection of various elements is imperative.The noise of target and of video amplifier can be neglected when the converter stages produce sufficient target electrons per incident primary electron. The required gain depends on the type of the tube and also on the type of the signal processing chosen. For EBS tubes, for example, it exceeds 10. The ideal case, in which all impinging electrons create uniform charge peaks at the target, is not obtainable for several reasons, and these will be discussed as they relate to a system with a scintillator, fiber-optic and photo-cathode combination as the first stage.
