We have made a preliminary map of the Horsehead nebula in CO (J=1-0) using the NRO 45-m telescope. The HPBW is 15″, the grid spacing 10″, and the velocity resolution is ∼0.1km/s. Figure 1 shows the integrated intensity with a velocity interval 10-11.5 km/s, which we found represents well the shape of the dark globule of the Horsehead. The coincidence of the CO feature and the dark nebulocity is strikingly well, especially at the sharp edges in the south and in the west (from the neck to the ears). The quality of the data are not satisfactory, though. The typical noise level is 1 K rms in TA, and the accuracies of the pointing and the intensity calibration is rather low due to the bad weather during the observation. Some scanning effects in the intensities can be recognized in Figure 1. One of the reason why the gap obtically seen beneath the jaw is not clear in the CO map may be attributed to the pointing errors.

Abstract Heymans, J. J., Howell, K. L., Ayers, M., Burrows, M. T., Gordon, J. D. M., Jones, E. G., and Neat, F. 2011. Do we have enough information to apply the ecosystem approach to management of deep-sea fisheries? An example from the West of Scotland. – ICES Journal of Marine Science, 68: 265–280. There is currently a global call for more use of an ecosystem approach to fisheries management (EAFM), and ecosystem models such as Ecopath with Ecosim (EwE) are being used to provide a holistic view of ecosystem–fisheries interactions. Although these can be useful for an EAFM, the relative paucity of data available for deep-sea ecosystems raises concerns whether we can effectively apply an EAFM to the deep sea. The deep-sea ecosystem off the west coast of Scotland has been studied for longer and in more detail than most. This study assimilates the significant published and unpublished information available on this ecosystem into an EwE model. The results suggest that there are sufficient data available to construct an ecosystem model, but the quality of the data varies and serious potential sources of error are present in biomass and discard estimates. The assumptions needed to produce a model are varied and must be considered when interpreting the outputs of the model. Ecosystem modelling provides a unique view of the deep-water ecosystem and facilitates hypothesis development concerning predator–prey and inter-fishery interactions. Sharks are used to illustrate the benefits of using an ecosystem model to describe changes in their biomass and their prey species. The results show that both fishing for sharks and fishing for their prey affect the biomass of sharks.

St Symeon the New Theologian is, without question, one of the most original and intriguing writers of medieval Byzantium. Indeed, although still largely unknown in the West, he is surely one of the greatest of all Christian mystical writers; not only for the remarkable autobiographical accounts he gives of several visions of the divine light, but also for the passionate quality of his exquisite Hymns of Divine Love, the remarkable intensity of his pneumatological doctrine, and the corresponding fire he brings to his preaching of reform in the internal and external life of the Church. He was a highly controversial figure in his own day. His disciples venerated him as a saint who had returned to the roots of the Christian tradition and personified its repristinization. His opponents, who secured his deposition and exile, regarded him as a dangerously unbalanced incompetent who, by overstressing the value of personal religious fervour, had endangered the stability of that tradition. The Vita which we possess was composed in 1054, in an attempt to rehabilitate Symeon’s memory and prepare for the return of his relics to the capital from which he had been expelled when alive. This paper will investigate how he himself understood and appropriated aspects of the earlier tradition (particularly monastic spirituality), hoping to elucidate why he felt himself inspired to reformist zeal, and why many of his contemporaries (not simply his ‘worldly opponents’ as his hagiographer would have us believe) regarded him as unbalanced. It will end by attempting some reflection on what the controversy reveals on the larger front about how the Church ‘selectively looks back on itself, so to paraphrase our president’s description of the conference theme, and whether the model of tradition and its reception exemplified in this Byzantine writer can offer anything to the dialogue between history and theology which the doctrine of Tradition (Paradosis) inevitably initiates.

Influence Of Noise

Population growth in Depok City is large and not in accordance with development land causes many residents’ to build houses with conditions <5 meters from the line of Electric Rail Train or Kereta Rel Listrik (KRL); this causes changes in the quality of the environment, including noise. The objective of this study is to determine the noise level, and the results will be compared with the standard noise level of the residential area; also, to find the influence of noise on residents’. This research was conducted in the area of ​​Rawa Geni Raya Street, 1st Neighborhood, Ratu Jaya Urban Village, Depok City. Noise measurements were carried out at 5-points using a simple method with a noise level measuring instrument (SLM). At one time, the measurement was taken for 10 minutes with a reading time of every 5 seconds. The questionnaire was measured using a Purposive Random Sampling technique, and the number of samples was calculated using the Slovin formula. The results of this study indicate that the 5-point noise level exceeds the recommended threshold according to KEPMEN LH 48 of 1996 and PERMENKES 718/1987 at  55 dB(A). The largest value for the 24-hour noise level (LSM) is at point 1, which is 5 m from the KRL line. The noise level on the weekday is 75.32 dB(A) and 74.24 dB(A) on weekends. According to PERMENKES No 718/1987, the location of point 1 should be included in Area D as an industrial zone, plant, railway station, and bus terminal. The results of questionnaires by 34 respondents showed that the noise generated by KRL was noisy and the majority of respondents agreed the noise affected the comfort level; in terms of health, respondents agreed KRL noise caused sleep disturbances and hearing loss.

Negative Impacts

In recent years, Mizoram has made immense progress in various sectors and initiated developmental programmes for its economic growth. An important contributing factor to this development and growth is the transport connectivity projects. Although connectivity projects can boost economic growth, its negative effects cannot be neglected. In view of this, the present research studies the impacts of Champhai – Zokhawthar road construction on the air quality and noise quality of the region. This comparative study of the impact on the quality of air and noise pollution in the pre-construction phase and construction phase provide a clear-cut example of the negative impacts caused by road construction and provide a fresh outlook for formulation of improved management plans. Air quality assessment was carried out using High Volume Air Sampler and the following parameters were monitored – suspended particulate matter (SPM), respirable suspended particulate matter (RSPM), nitrogen dioxide (NO2) and sulphur dioxide (SO2). The results indicate that mean SPM concentration was increased by 22.82 µg/m3; RSPM concentration by 14.67 µg/m3; NO2 concentration by 4.08 µg/m3; and SO2 concentration was increased by 0.06 µg/m3 from the pre-construction phase to construction phase. Noise quality assessment was carried out at three sites – Zotlang, Melbuk and Zokhawthar by using Lutron SL-4001 Sound Level Meter and Leq, Lmax and Lmin were recorded and calculated. The mean noise level at Zotlang wasincreased by 8.72 dB (A) and at Melbuk the mean noise level was increased by 9.35 dB (A). However, at Zokhawthar, there was a decrease in mean noise level by 0.13 dB (A). From the present study, it is evident that road construction poses a threat to the air quality and noise quality of the study area and improved measuresneed to betaken to curb its negative impacts

IMPORTANCE The appropriate use of facemasks, recommended or mandated by authorities, is critical to protect the community and prevent the spread of COVID-19. OBJECTIVE To evaluate the frequency and quality of facemask use in general populations of different socio-spatial backgrounds. DESIGN A multi-site observational study carried out from 25 June 2020 to 21 July 2020. SETTING The observations were carried out in 43 different locations in a region in the west of France, representing various areas: rural and urban, indoor and outdoor, and in areas where masks were mandated or not. An observer was positioned at a predetermined place, facing a landmark, and collected information about the use of facemasks and socio-demographic data. PARTICIPANTS All individual passing between the observer and the landmark were included. EXPOSURE The observer collected information on whether a mask was worn, the type of mask used, the quality of the positioning, gender, and the age category of each individual. MAIN OUTCOMES AND MEASURES The main outcomes were the use of a facemask and the quality of the positioning. Factors associated with these outcomes were identified. RESULTS A total of 3354 observations were recorded. A facemask was worn by 56.4% (n=1892) of individuals, varying from 49% (n=1359) in non-mandatory areas and 91.7% (n=533) in mandatory areas, including surgical facemasks (56.8%, n=1075) and cloth masks (43.2%, n=817). The facemask was correctly positioned in 75.2% (n=1422) of cases. The factors independently associated with wearing a facemask were being indoors (adjusted odds ratio [aOR], 0.37; 95% confidence interval [CI], 0.31-0.44), being in a mandatory area (aOR, 0.14; 95%CI, 0.10-0.20), female gender (aOR, 0.57; 95%CI, 0.49-0.66), and age >40 years (aOR, 0.54; 95%CI, 0.46-0.63). The factors independently associated with correct mask position were rural location (aOR, 0.76; 95%CI, 0.97-0.98), being in an indoor area (aOR, 0.49; 95%CI, 0.38-0.65), use of a cloth mask (aOR, 0.65; 95%CI, 0.52-0.81), and age >40 years (aOR, 0.61; 95%CI 0.49-0.76). CONCLUSIONS AND RELEVANCE Information campaigns should promote the use of cloth masks. Young people in general and men in particular are the priority targets. Simplifying the rules to require universal mandatory masking seems to be the best approach for health authorities.

Privately Owned

The urban development and rapid urbanization that the West Bank, including occupied East Jerusalem and Gaza Strip have recently encountered have adversely affected the quality and availability of open spaces inside the Palestinian urban and rural areas. Public spaces are fundamental in the lives of any community striving to achieve a sustainable and inclusive environment and improve the quality of life of its inhabitants. In that respect, the prevailing planning practices fall short in terms of adequately addressing the provision of public spaces. Laws and regulations are designed to focus on limited physical properties of buildings (e.g. building design, elevation, heights, setbacks, parking, etc.,) with little or no attention to the residual space, inevitably, created between those blocks. Lands are chiefly privately owned, and considered of a very high value due to the artificial land scarcity phenomenon resulted from the geo-political classification of the West Bank Existing public spaces are not welcoming to the general public. Spaces are misplaced and scattered, they offer pre-defined activities and an inflexible environment. Many parts of the society feel alienated to such public spaces, created by a top-down process with minimal integration of their needs and aspirations.

Gastric cancer is the leading cause of death among all cancer deaths. Identification of risk groups and special carcinogens will prevent the development of the tumor or detect it in the early stages, which will significantly increase the quality of life of patients with high risks of developing gastric cancer. For the timely detection of tumor development, it is optimal to use systematic screening. Undoubtedly, the approaches to the diagnosis of cancer have significant differences in the countries of the West and the East.
