Aerofracture through a double looking glass, mixing optics and acoustics

The characterization and comprehension of rock deformation processes due to fluid flow is a challenging problem with numerous applications in many fields. This phenomenon has received an ever-increasing attention in Earth Science, Physics, with many applications in natural hazard understanding, mitigation or forecast (e.g. earthquakes, landslides with hydrological control, volcanic eruptions), or in the industry, as in CO2 sequestration, production and reservoir exploitation, or borehole stability problems. Even though fluid flow, rock deformation [1] or granular dynamics [2] are vast phenomena to understand individually [3], the coupled behaviour of flow in deformable porous media with a dynamic fluid flow makes the system even more intricate to comprehend. The dynamic interaction between flow and the porous media, rapid changes in the local porosity due to the compaction, dilation and migration of the porous material, fracturing due to the momentum exchange in fast flow, make understanding of such a complex system a challenge.

Relationship Between Growth of Rice Seedlings and Time of Infection with Meloidogyne graminicola

: Early infection of Meloidogyne graminicola significantly reduced the growth of rice plants. In general length and fresh weight of shoot and root decreased significantly with earliness in time of inoculation. Seedlings inoculated 24 h after germination recorded minimum growth of the plant, whereas growth parameters increased with increasing gap in time of inoculation. Onset of yellowing was observed on day 8 in the seedlings inoculated 24 h after germination while seedlings inoculated 2 days after 1 inoculation expressed it on day 10. st Seedlings inoculated 14 days after 1 inoculation exhibited least effect of M. graminicola on the growth st parameters followed by those inoculated 12 and 10 days after 1 inoculation. Nematode biomass in the roots st of inoculated seedlings decreased with increasing gap in time of inoculation whereas root biomass consistently increased. The nematode-to-root biomass ratio was lower in the seedlings which were inoculated after 24 h of germination and 2 days after 1 inoculation which resulted into wilting. Nematode-to-root biomass ratio st increased with increasing gap in time of inoculation that led to delay in onset of yellowing. Time of inoculation was positively correlated with shoot length (R = 0.90), root length (R = 0.77), fresh weight of shoot (R = 0.96), 2 fresh weight of root (R = 0.97) and nematode-to-root biomass ratio (R = 0.20) while it was negatively correlated 2 2 with number of root galls (R = 0.75), number of females (R = 0.82), total population (eggs + juveniles) of 2 2 nematodes (R = 0.77) and nematode biomass (R = 0.82). 2

Pricing structures for solutions: an exploratory study within the oil and gas industry†

A growing number of companies have begun to realise the potential for differentiating their product offerings by integrating services to provide customised solutions. Although there is now an extensive and growing literature on this trend, researchers have only recently begun to consider the pricing structures for such solutions. To address this shortcoming, the present study adopts an exploratory case-based approach to investigate a buyer (drilling contractor) and two suppliers of offshore capital equipment, each of whom provides condition-based maintenance solutions for offshore drilling units in the upstream oil and gas industry. The findings of the study identify a number of underlying mechanisms for solution offerings (i.e. innovativeness, benchmarking alternatives, measurability, replicability and operational risk) that are important considerations in the process of determining appropriate pricing structures based on the buyer’s business model, procurement practices and maintenance strategy vis-à-vis the supplier’s capabilities and the buyer–supplier relationship. The present study contributes to the literature by providing empirical evidence on and insight into the complexity of determining the pricing structure for solution offerings from the perspective of the supplier as well as the buyer.
Occupational Vibration in Urban Bus and Influence on Driver’s Lower Limbs:

The whole-body vibration occurs in many occupational activities, promoting discomfort in the working environment and inducing a variety of psycho – physical changes where consequences as a permanent dysfunction of certain parts of the organism may occur. The main goal of this short systematic review is finding the articles with the most reliable results relating whole-body vibrations to buses and, to compare them with the results of drivers’ lower limbs musculoskeletal disease which occurs as a consequence of many year exposure. PRISMA Statement Methodology was used and thereby 27 Scientific Journals and 25 Index - Database were searched through where 3996 works were found, of which 24 were included in this paper. As a leading standard for analysis of the whole-body vibration the ISO 2631 – 1 is used, while in some papers as an additional standard the ISO 2631-5 is also used for the sake of better understanding the vibrations. Furthermore, the European Directive 2002/44 / EC is included where a daily action exposure to the whole-body vibrations is exactly deter-mined. All the results presented in the paper were compared with the aforesaid standards. After having searched the databases, papers that deal with research of the impact of the vibration on the driver’s lower limbs did not contain any information’s on the described problem.
THE PROCESS OF POST-MERGER INTEGRATION: A REVIEW AND AGENDA FOR FUTURE RESEARCH

Mergers and acquisitions continue to be prevalent despite frequently yielding disappointing outcomes. Post-merger integration plays a critical role in M&A success, yet many questions about M&A implementation remain unanswered. In this article, we review research on post-merger integration, which we organize around strategic integration, sociocultural integration, and experience and learning. We then lay out a research agenda that centers on expanding our understanding of processual dynamics in post-merger integration. We focus on opportunities related to temporality; decision-making; practices and tools; and emotionality.
Multiline holding based control for lines merging to a shared transit corridor

ABSTRACT In transit corridors, multiple lines share a sequence of consecutive stops to provide higher joint frequency in higher demand areas. A key challenge is to coordinate the transition from single line to joint operation. A holding control strategy aimed at minimizing passenger travel times is introduced for lines merging into a shared corridor, accounting for the coordination of vehicle arrivals from the merging lines as well as the regularity of each line. The criterion is tested using an artificial network and a real-world network to analyze the impact of demand distribution and compare cooperative versus single line control. We illustrate how the real-time strategy yields overall passenger gains, depending on the composition of different user groups. Results are assessed based on operation and passenger performance indicators and show that coordination is achieved. When combined with joint control in the common part, the proposed approach achieves consistent network-wide travel time benefits.
Occurrence and characterization of peripheral nerve involvement in neuroﬁbromatosis type 2

the classiﬁcation of neuropathy, correlation to clinical ﬁndings, and histological ﬁndings of a sural nerve biopsy. We conclude that peripheral neuropathy, mostly of axonal type, is a common clinical ﬁnding in NF2. We hypothesize that the aetiology of this frequent peripheral neuropathy syndrome in NF2 is caused by compression effects of multiple tumourlets, originating along the length of the peripheral nerves on adjacent nerve ﬁbres, by local inﬂuences of the endoneurial pathological cells on adjacent nerve ﬁbres and/ or the inability of these cells to properly adhere to, or ensheath, the axon. prolonged DML, distinct reduced CMAP of the tibial nerve, reduced SNAP of the sural nerve and neurogenic pattern in EMG. Case 5 had an axonal neuropathy because of prolonged DML of the tibial nerve and of the median nerve, reduced SNAP of the sural nerve and neurogenic pattern in EMG. In Case 6, absent sural nerve SNAP, prolonged DML, reduced CMAP and reduced NCV of the tibial nerve, and reduced sensible NCV of the median nerve were documented leading to mixed axonal–demyelinating neuropathy with axonal component of demyelination. Case 8 showed reduced SNAP of the sural nerve. In Case 9 prolonged DML of the tibial nerve, absent sural nerve potential, prolonged f-wave latency and reduced sensible NCV were documented. A mixed axonal–demyelinating neuropathy was supposed. Case 10 showed reduced SNAP of the sural nerve and median nerve, CMAP at lower limit of the median nerve and discrete reduced NCV of the median nerve. EMG was not done because of patients declining. An axonal lesion was documented. In Case 11, prolonged f-wave latencies of the median and tibial nerve were documented.
Evaluation of Heavy Metals and Microbial Properties of Leachate and Hard Water Samples from Lemna Dumpsite in Calabar

Evaluation Heavy Metals and Properties of Leachate and Hard Water Samples from Lemna Organization; NDWQS: Nigeria Drinking Water Quality Standard; LSD: Least Significant Difference Test; NS: No Signifi -cance; THBC: Total Heterotrophic Bacteria Count; TCC: Total Coliform Count; TFC: Total Fungi Count; LSD: Least Significant Difference; H2S: Hydrogen Sulphides; WSA: Water Sample Containing Leachate; WSB: Water Sample Containing Hard Water This present study evaluated the levels of heavy metals and microbial properties of leachate and hard water samples obtained from lemna dumpsites. The heavy metals in leachate and hard water samples were determined using the WAGTECH photometer (Model 7100) for the analysis of iron, chromium, manganese, zinc, copper and aluminium while WAGTECH Arsernator Model W5000063 for the analysis of arsenic. Microbial population in samples were determined using standard microbiological procedures. The result showed that the leachate samples yielded the highest total heterotrophic bacteria counts of 6.2× 10 5 CFU/ml, while the hard water yielded the highest total coliform counts of 3.07 × 10 5 CFU/ml and total fungi count of 4.2 × 10 5 CFU/ml. The prevalent bacteria species from the leachate and hard water samples were Streptococcus feacalis, Escherichia coli, Pseudomonas aeruginosa, Serratia marcensen, Staphylococcus aureus and Bacillus subtilis and four fungal species were identified: Penicillium spp, Aspergillus spp, Fusarium spp and Yeast spp . The result of the heavy metal analysis shows that the sequence of leachates content in the heavy metals determined in this study follows the trend: Cu > Al > Zn > Fe > Cr > Mn > As while the sequence in hard water was Fe > Al > Cu > Zn > Mn > Cr > As having the lowest to be arsenic indicating absence of Arsenic in the hard water samples. This imply that virtually most of the parameters determined were above the World Health Organization/Nigeria Drinking Water Quality Standard permissible limits for drinking water. It was concluded that the levels of contaminants present in the dumpsite could be hazardous to the management staff of the dumpsite. Government should develop a sustainable plan for effective management and recycling of generated wastes to caution it impact on neighboring underground water table.
Face Value. Perception and Knowledge of Other People’s Happiness

Happiness, like other basic emotions, has visual properties that create the conditions for happiness to be perceived in others. This is to say that happiness is perceivable. Its visual properties are to be identified with those facial expressions that are characteristic of happiness. Yet saying that something is perceivable does not suffice for us to conclude that it is perceived. We therefore need to show that happiness is perceived. Empirical evidence suggests that the visual system functions to perceive happiness as well as other basic emotions. Experiences that can be had simply by virtue of how the perceptual system functions are known as observations. I will thus argue that visual experiences in which we become aware of others’ happiness are observations. This approach will provide the necessary conceptual framework to show that we have perceptual knowledge of others’ happiness.
Role of External Ear in Establishing Personal Identity - A Short Review

Since centuries external ear and its peculiarities had been attracting the attention of Scientists from diverse fields of Science. The possibility of using the external ear as a tool for establishing the unique identity of individuals was first recognized by Bertillon who included the same in the system he developed in 1893. Since then several studies on its range of peculiarities in morphology have emerged especially to correlate it with the field of personal identification. With the emergence of ‘Information age’ even the field of criminology has broadened its horizon by including more and more morphological features (face, hand, finger, iris etc.) for establishing identity. This paper traces this historical journey of the maturation study from the first step taken by Bertillon, to a foolproof personal identification trait that it is today.

Measurement of four-photon absorption in GaP and ZnTe semiconductors

: Intensity-dependent eﬀective four-photon absorption (4PA) coeﬃcients in GaP and ZnTe semiconductors were measured by the z-scan method using pump pulses of 1.75 µm wavelength, 135 fs duration, and up to 500 GWcm − 2 intensity. A nonlinear pulse propagation model, including linear dispersion and 4PA was used to obtain the 4PA coeﬃcients from measurements. The intensity-dependent eﬀective 4PA coeﬃcients vary from 2.6 × 10 − 4 to 65 × 10 − 4 cm 5 GW − 3 in GaP, and from 3.5 × 10 − 4 to 9.1 × 10 − 4 cm 5 GW − 3 in ZnTe. The anisotropy in 4PA was shown in GaP. The knowledge of 4PA coeﬃcients is important for the design of semiconductor photonics devices. under the terms of the OSA Open Access Publishing Agreement
pictures for communicating information about Alzheimer's disease Does a picture tell a thousand words? The uses of digitally produced, multimodal

This study explored the science communication potential of visual imagery by gauging an audience’s interpretations of digitally enhanced, multimodal pictures depicting topics from recent Alzheimer’s disease research. Guided by social semiotic theory, we created four pictures intended to communicate information about Alzheimer’s disease unidirectionally, for an audience who had expressed interest in receiving such information (subscribers to an Alzheimer’s disease research newsletter). We then disseminated the pictures to that audience via an online survey, to determine whether respondents received the messages we intended to convey. Our results demonstrated that, without accompanying explanatory text, pictures are most useful for evoking emotions or making loose connections between major concepts, rather than for communicating specific messages based on Alzheimer’s research. In addition, participants more often expressed anger and frustration when the meaning of scientific imagery was unclear than when the meaning of emotional–social imagery was unclear.
CHEMICAL AND OPTICAL PROPERTIES OF MnO 2 THIN FILMS PREPARED BY REACTIVE EVAPORATION OF MANGANESE

Thin films of manganese oxide were deposited by thermal reactive evaporation of pure manganese. The films were deposited at room temperature under various oxygen partial pressures. Structural analyses were performed by X-ray diffraction and atomic force microscopy. The films were polycrystalline and the surface roughness of the films was oxygen partial pressure-dependent. Chemical analysis, studied by x-ray photoelectron spectroscopy, exhibited the control of stoichiometry in the films by varying the oxygen partial pressure, where fully oxidized MnO 2 films were obtained at higher oxygen partial pressures. Optical measurements revealed a slight decrease in the transmittance of the films prepared at higher oxygen partial pressures. Gradual increase in the direct band gap of the films with oxygen partial pressure was noted. Based on the structural and chemical characterizations, the optical properties (refractive index and extinction coefficient), of the stoichiometric MnO 2 film were investigated.
Remote Sounding of Vertical Profiles of Atmospheric Ozone and Nitrous Oxide with a Tunable Diode Las

Observations of atmospheric ozone and nitrous oxide were performed with a laser heterodyne spectrometer using a tunable diode laser as a local oscillator at Sendai (38*15'N, 140*51'E), Japan from November 1988 to June 1989. The absorption line spectra measured with ultra high resolution of 0.0013 or 0.0027 cm-1 (40 or 80 MHz) were inverted by a conventional inversion method to retrieve vertical distribution profiles. The observed altitude range is from 5 to 30 km for ozone and from 1 to 35 km for nitrous oxide and the vertical resolution is*5 km. Total column densities were also obtained by integrating the vertical profiles. Errors in the retrieved mixing ratio profiles were estimated by computer simulations for all the plausible causes: <10 % arising from uncertainties in line parameters, *3 % from random noise in the spectra when SNR=500, and <3 % from difference between model and actual temperature profiles. For total column densities, the random error is <3 %, while systematic error due to uncertainty in the line strength is <10 %. The retrieved vertical profiles of ozone from January to June 1989 show seasonal and day-to-day variations usually seen in middle latitudes. The total column densities were compared with those measured by Dobson spectrophotometers at Tateno and Sapporo. The result is consistent with the latitudinal dependence of total column density of ozone. The vertical profiles of nitrous oxide were also obtained by the same procedure as for ozone. The result for nitrous oxide agrees with the data obtained by a balloon observation at Sanriku (39*09'N, 141*49'E).
CURRENT APPRAISAL OF THE SUITABILITY OF FOOT-AND-MOUTH DISEASE STRAINS IN TWO COMMONLY USED COMMERCIAL VACCINES FOR CONTROL OF FMD IN PAKISTAN

Vaccination is the primary tool used to control Foot-and-mouth Disease (FMD) in Pakistan. FMD virus mutates regularly in the field and new sub-serotypes continue to emerge. For vaccine to be effective, the vaccine should contain viruses that induce immune response to neutralize the circulating field viruses. This study was undertaken to evaluate if the two commonly used imported FMD vaccines produce sufficient antibodies to neutralize circulating field FMD isolates. Pooled sera from 5 buffalo calves raised against vaccine I and II was used in the serum neutralization test to neutralize 7 field strains of FMD virus serotypes A, O and Asia-1.The field strains of FMD virus were better neutralized with vaccine I than vaccine II. Serotype O and Asia-1 field strains were effectively neutralized with vaccine I antisera. However, low serum neutralization titres were observed against serotype A field isolates suggesting that serotype A strains present in both vaccines need to bebetter matchedwith field strains for effective protection.
Role of 02 and Mitochondrial Respiration in a Photosynthetic Stimulation of Oat Protoplast Acidification of a Surrounding Medium1

Some photosyntheticaly stimulated acidification of the medium by oat (Avena sativa L. cv Garry) leaf protoplasts required respiration. The requisite respiration (a) had a low apparent affinity for 02, (b) was Mocked by cyanide plus salicylhydroxamic acid, (c) characterized protoplasts and mitochondria isolated from protoplasts, (d) could be induced In leaf segments, and (e) appeared to result from an inhibition of mitochondrial respiration that included the cytochrome pathway. Carbon monoxide and cyanide prevented acidification of weakly photosynthesizing suspensions. Salicylhydroxamic acid had no effect on acidification, indicating a specific dependence upon cyanide-sensitive respiration. Photosynthesis stimulated acification through stable products, and exogenously supplied 02 stimulated acidification. The acidification respnse to 02 was addtive to the response to photosynthesis at subsaturating levels of Lght, indicating a common mode of action. Oligomycin prevented stimulation of acidification by low levels of photosynthetic activity, this stimulation appeared to be due to 02-induced increases in mitochondrial energy production. Olgomycin only partially inhibited stimulation of acidification by higher levels of iht; this stimulation appeared to be partially dependent upon photophosphorylation. Therefore, oligomycin-sensitive acidification of the medium appeared to reflect changes in mitochondrial energy production in photosynthesizing protoplasts.
Urine nucleic acid test positive in an asymptomatic patient with novel coronavirus 2019 infection: a case report

Background: With the emergence of coronavirus disease 2019 in many places around the world, the main medical resources currently focus on the treatment of confirmed patients and the screening of suspected cases. Asymptomatic patients are difficult to detect, but they may be contagious, which makes epidemic control more difficult. We found a case of asymptomatic patient with positive urine coronavirus nucleic acid test, and we hope to attract attention of all circles. Case presentation: An asymptomatic patient with novel coronavirus infection was found in an epidemiological investigation of patients with confirmed coronavirus disease 2019. The patient was admitted to the hospital on February 24, 2020. She had no clinical manifestations such as fever, dry cough, and fatigue, and no abnormal signs. The examination showed that her throat swab was negative for nucleic acid but the urine was positive for nucleic acid. She was given antiviral and symptomatic supportive treatment. On February 26, her throat swab was checked for nucleic acid positive. On March 3 and 5, her throat swab and urine nucleic acid were negative. On March 9 and 12, her throat swab nucleic acid were negative. The patient was discharged from the hospital on March 13 and continued to be isolated and observed outside the hospital. Follow-up was conducted on March 26, the patient did not have any discomfort, the throat swab nucleic acid test was negative, and the isolation was lifted. Conclusion: There are asymptomatic patients with coronavirus disease 2019, and their urine may be one of the sources of infection.
