Abstract Sediment gravity flows are the primary process by which sediment and organic carbon are transported from the continental margin to the deep ocean. Up to 40% of the total marine organic carbon pool is represented by cohesive extracellular polymeric substances (EPS) produced by microorganisms. The effect of these polymers on sediment gravity flows has not been investigated, despite the economic and societal importance of these flows. We present the first EPS concentrations measured in deep-sea sediment, combined with novel laboratory data that offer insights into the modulation of the dynamics of clay-laden, physically cohesive sediment gravity flows by biological cohesion. We show that EPS can profoundly affect the character, evolution, and runout of sediment gravity flows and are as prevalent in deep oceans as in shallow seas. Transitional and laminar plug flows are more susceptible to EPS-induced changes in flow properties than turbulent flows. At relatively low concentrations, EPS markedly decrease the head velocity and runout distance of transitional flows. This biological cohesion is greater, per unit weight, than the physical cohesion of cohesive clay and may exert a stronger control on flow behavior. These results significantly improve our understanding of the effects of an unrealized biological component of sediment gravity flows. The implications are wide ranging and may influence predictive models of sediment gravity flows and advance our understanding about the ways in which these flows transport and bury organic carbon globally.

Biometrics in the Art of New Media The review is devoted to the main themes presented in the book by Ewelina Twardoch-Raś Sztuka biometryczna w perspektywie filozofii post- i transhumanizmu. W stronę estetyki postafektywnej [Biometric Art in the Perspective of the Philosophy of Post- and Transhumanism. Towards Post-affective Aesthetics]. The author emphasizes the pioneering nature of this publication on a global scale, because so far no monographic author’s study of this issue has been published. Biometric art can be included in the broad context of contemporary new media art, but its specificity is considered in this case primarily in the context of posthumanist and transhumanist philosophy and the author’s interpretation of post-affective aesthetics. The review pays particular attention to the author’s accurate recognition that biometric art is a practical step beyond the world of new media and establishing a new area of post-media practice. In this case based on biomediation defined as “post-media hybridization” of biological and technological components.

The present study offers an alternative method for green synthesis of the formation of two types of nanoparticles (NPs). These NPs, titanium oxide and silver NPs (TiO2 and Ag NPs, respectively), were obtained from the amalgamation of intracellular extract of a wild mushroom, Fomes fomentarius, with aqueous solutions of titanium isopropoxide and silver nitrate, respectively. F. fomentarius was identified phenotypically and by 18S ribosomal RNA gene sequencing (Gene accession no: MK635351). The biosynthesis of TiO2 and Ag NPs was studied and characterized by X-ray diffraction (XRD), diffuse reflectance UV-Visible spectroscopy (DR-UV), fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscope (TEM). Success was achieved in obtaining NPs of differing sizes and shapes. The antibacterial and anticancer activity of the NPs was significant with morphological damage being caused by both, although Ag NPs (10–20 nm) were found to have profound effects on bacterial and cancer cells in comparison to TiO2 NPs (100–120 nm). These metal NPs, synthesized using wild mushrooms, hold a great potential in biomedicinedue to an effective enzyme combination, which permits them to modify different chemical compounds to less toxic forms, which is required for ecofriendly and safe biomaterials.

Judicial authority in Indonesia is carried out by a Supreme Court and the Constitutional Court which has the authority to examine laws against the 1945 Constitution of the Republic of Indonesia and decide on the authority dispute of state institutions whose authority is granted by the 1945 Constitution of the Republic of Indonesia. The Constitutional Court in examining the Law against the 1945 Constitution became a polemic related to the prejudicial object which was finally answered through the decision of the Constitutional Court (MK) number 21 / PUU-XII / 2014. The Constitutional Court granted part of the application for corruption convictions in the case of PT Chevron Bachtiar's Abdul Fatah biomediation project, one of which examined the prejudicial object provisions which were polemic, especially after the South Jakarta District Court's prejudicial has canceled the status of suspect Commissioner Budi Gunawan (BG) by the KPK. This study is a legal research using a normative juridical approach and descriptive analytical research specifications. The data used in this study are secondary data consisting of primary, secondary and tertiary legal materials. Data obtained through library studies and field research in the form of legislation, books, journals, and authoritative electronic media. The results of this study are 2 (two) explanations, namely First, Constitutional Court Judges have made legal inventions by providing interpretations and limitations on what can be the object of prejudicial in criminal procedural law by testing it against the constitution and seeing whether the KUHAP Articles tested are contradictory with constitutional rights. Secondly, the Constitutional Court uses several interactive techniques used by member judges in decision number 21 / PUU-XII / 2014. In the joint decision, the judges used Authentic, Systematic, Grammatical, Historical, Extensively and sociological interpretation techniques. This can be seen in the decision of point one stating a phrase which means interpreting the law using grammatical techniques

Background/Aim: Fractures are the most common form of trauma in current orthopedic practice. Although studies have shed light on the relationship between the factors affecting the healing process after fracture, this process is still not fully understood. In this study, we aimed to investigate the changes in serum biomediator levels and fracture healing in different trauma patterns, such as head trauma (HT), long bone fracture (LBF), a combination of HT + LBF injury (CI), and in different time points of the healing period. Methods: Forty Wistar rats were included in the study and divided into five groups. Group 1, the donor group, included rats with HT; Group 2 included rats with LBFs who were administered the serum taken from rats in Group 1; Group 3 included the rats with isolated LBFs; and Group 4 the rats with CI. Group 5 comprised the control rats. An experimental closed HT and fracture model was applied to rats. The rats in Groups 2, 3 and 4 were sacrificed on the 10th, 20th, and 30th days. The biomediator levels in the serum taken after sacrification were studied, while closed femoral fracture models were examined radiologically. Results: Statistically significant differences were found among the groups regarding radiological scores on the 10th, 20th, and 30th days. On Day 10, Group 2a had significantly higher scores than Group 3a (P=0.03), and Group 3a had lower scores than Group 4a (P=0.01). On Day 20, Group 2b had significantly higher scores than Group 3b (P=0.004) but lower than Group 4b (P=0.03). On Day 30, Group 2c had significantly higher scores than Group 3c but lower than Group 4c (P=0.001). The mean Ca, TGF beta 1, beta-catenin, IL-10, IL-17A, TNF alpha, CRP, Wnt-16, ALP, GH, PTH, IL-1 beta, IL-6, and IL-22 levels were significantly different among the groups (P<0.05). No significant difference was observed in the biomediator levels among the groups at different time points of the healing period. Conclusion: We concluded that inflammatory cytokines (IL-1 beta, IL-6, IL-17A, IL-17F, IL-23, and TNF alpha) were elevated in the early period in individuals with isolated head trauma and that this effect could be transferred to other individuals by serum transfer. On the other hand, the negative relationship between the IL-10 level, which is a negative modulator in fracture union, and callus thickness was significant. Our study contributes by providing a molecular description of the positive union effect transferred between individuals by serum. We believe our findings will play a significant role in developing new therapeutic agents for fracture healing.

Annotation:

Laboratory experimentation in a large aimular flume (radius 3 m, channel width and water depth 0.4 m) has been conducted using a geometrically and dynamically similar Spariina anglica mimic (canopy height 0.21 m, stem density 1000 stems m~^) to investigate the influence of submerged Spartina on hydrodynamics under unidirectional currents {Uh = 0.2 m s~*) and the impact upon the dynamics of suspended cohesive sediments near the bed within the canopy. The vertical distribution of canopy biomass strongly influences vertical profiles of time-averaged velocity and turbulent quantities. An inflected velocity profile is observed in the region 0.79 < z/h < 0.9 which generates shear, T K E and Reynolds Stress peaks within vicinity of the canopy top. In this region T K E peaks at 15 times the levels observed in un-vegetated experiments. Flows at the canopy top are strongly intermittent with extremely efficient downward momentum transfer, uf] and ufz (stream-wise and vertical zero-mean fluctuating velocity) skewness are 0.5 and -0.5 indicating the presence of intermittent downward penetrating gusts. Near the bed (0 < z/h < 0.3) mean flow velocities are reduced by 88 - 90% in comparison to un-vegetated flows but turbulence intensities are strongly augmented by wake shedding from vegetative elements. TKE in this region is approximately equal to that in un-vegetated flows. Novel field observations in a low energ>', estuarine fringing marsh site on the Tavy Estuary, UK, with a vertical array of synchronous velocimeters and optical backscatter sensors exhibit low velocities (<0.6 ra s"*) and suspension concentrations (<100 mg L"*) in agreement with laboratory simulations. While field observations of near bed flows exhibit similarity to those measured in the laboratory, magnitudes of time-averaged flow throughout the water column are so small that the velocity profile appears constant over depth. Superimposed upon the low field velocities are small wind generated waves ( < 0.05 m in height and with periods < 3 s) which have a considerable impact on flow energy and stress estimates, but crucially, cannot be replicated in the laboratory experiments. Dissipation rates within the laboratory canopy are 70-200x10"'* m~^s"^ giving reduced Kohnogorov length scales of 0.04 - 0.14 mm. Field values for dissipation are generally of similar magnitude but peak at up to 600 X10"** m~^s~^. Kolmogorov length scales are consequently 0.06 - 2.6 mm. Using natural intertidal mud, suspension concentrations of 100-200 mg L~* have been sheared through the mimic canopy. Observations from a vertical array of miniaturised OBS sensors suggests sediments are maintained in suspension twice as long, under constant unidirectional currents, compared to un-vegetated flows. In the field initial concentrations of 100 mg L~* quickly decay to background levels of <20 mg L"* indicating the rapid setthng of material from suspension. Use of a novel digital in-line holographic particle iinaging system and the development of a particle tracking methodology has enabled the high resolution observation of both sample size and settling velocities of suspended cohesive particles. Laboratory observations of sample averaged size (74.5 - 111.7 mm) and settling rates (0.35 - 1 mm s~*) are in agreement with published estimates and the limited observational data that exists for settling rates in marsh systems. Settling velocities estimated in the field at 0.1 - 0.8 mm s~^. Significantly larger and fast settling aggregates have been observed than previously recorded. In the narrow range of experimental suspension concentrations and shear stresses utilised in the present experiments, significant diff^erences in particle size and settling velocity between vegetated and un-vegetated flows cannot be identified. Contrasting flux estimates using sample averaged settling rates and concentrations with full spectral estimates derived from the holographic particle imager indicate an error in the former fluxes of, on average, 62%. The range of settling rates observed during the pr^ent study raises questions regarding the accurate representation of marsh surface settling fluxes in numerical simulations. Large magnitude flux errors may have significant implications for accurate accretion rates in numerical models of marsh sedimentation.

Naturally occurring compounds have been used as pesticides since decades. That time of pesticides were most liable sulphurous rock, red pepper, extracts of tobacco, salt, and etc. Though the execution of the synthetic pesticides was a blessing for the world, yet the same has turned into a curse due to the heavy usage by people ultimately leading to their accumulation in the environment and taking its way in to the food web. We tried to investigate the negative effects of lindane on major food crop (wheat) in laboratory. We have found that mean shoot length decreased to 2.93 cm in 50 ppm lindane as compared to 10.2 cm in control. The corresponding mean root length were 0.86 cm and 10.64 cm indicating very heavy deleterious effect of increasing concentration of lindane on the development of wheat seedling even-though the percentage germination in 10, 20, and 50 ppm were very near to that of control (98%) while the percentage in 5 ppm was 84 % indicating heavy loss in the germination ability of seeds at low concentrations even though the mean root and shoot length were comparatively higher than the other concentrations. Many of the synthetic pesticides have been shown to persist in nature and their degradation is either very slow (longer half- life) or negligible. Most of the pesticide remained unused and entered into the ecosystem. These excessive pesticide residues accumulate in the biosphere and create ecological stress. Soil and water are the ultimate sinks for the excessive pesticides. Microbial degradation involves the use of microbes to detoxify and degrade environmental contaminants. The study on co-metabolic mineralization of organochlorine pesticide (lindane) was undertaken for this project. We isolated morphologically four different strains of bacteria by enrichment technique and designated them as LRN1, LRN2, LRN3 and LRN4 respectively. These four strains viz. LRN1, LRN2, LRN3 and LRN4 were able to individually act on lindane co-metabolically thereby reducing the initially added concentration to approximately 80% in a very short period of 5 days under aerobic conditions. Co-metabolism is the best applicable bioremediation methods and the use of consortium is a promising approach .Our 4 strains may be constituted into a defined consortium and applied to the contaminated sites for efficient treatment. Further studies need to be conducted to optimize the conditions and investigate the enhanced efficiency of these four strains individually and in combinations to develop best remediation technologies.

2 Abstract In this text, we are asking if it is possible to think the 'psychedelic' without labelling it as 'different', 'imaginary', 'fantastic' or 'unreal', and without thinking it as a particular experiential region belonging specifically to human experience. By first thinking 'experience', we are then attempting to relate the psychedelic experience to human experience considered in the simple joining of its basic dimensions, and to think both of these experiential modalities through the same motives. If we think 'experience' as opening itself through its boundaries, which limit and thus open the dimensions through which the fundamental relation of presencing and apprehension plays, then we can think the psychedelic using the concept of 'layer' derived from the concept of 'boundary'. We first think the phenomena of transparency of time, of transparent attunement and of transparent clarity, which belong to human experience in its simplicity. We then think the phenomenon of disjoining of the basic dimensions of human experience, which takes us from human experience in its simplicity, through strangeness, towards the psychedelic. Lastly, we think the phenomenon of permeating, taking us to the simply joined or disjoined dimensions of human and non-human experience being played out in their layeredness...

The medical mediation of bodily differences can be fraught, and many scholars have shown how the combination of media and medicine can produce disablement according to biopolitical norms. Mack Hagood proposes a framework for the study of biomediation that disentangles medical uses of media technologies from the medical model of disability. Using tinnitus as his case study, he demonstrates the value of this framework for understanding the complex role of media in both biological and political struggles over disability and disabled identities.

This chapter explores how the embodied dynamics of illness and chronicity shape online modes of health-seeking by comparing the experiences of people living with spinal cord injuries (SCIs) to those of people suffering from amyotrophic lateral sclerosis (ALS). As diverse biological conditions become increasingly mediated by digital modes of representation, these emergent forms of “biomediation” catalyze new hopes and possibilities for those seeking to challenge orthodox prognoses and bodily limitations. While the chronic nature of SCI enables the formation of robust and stable online communities such as CareCure, the cybersociality cultivated by people living with the immediate threat of ALS is much more contingent and ephemeral. The kinds of social connections forged online in turn shape the forms of mobilization and digital pathways to experimental medicine.
