Pierwsi rolnicy na ziemi kociewskiej - refleksja z najnowszych odkryć archeologicznych

The article is aimed at presentation of a newly discovered Linear Band Pottery settlement at Kościelna Jania, Smętowo Graniczne commune. The site was excavated during rescue works on the Al highway. It has been the largest settlement o f this culture in the Starogard Lake District explored to date. In 21 excavated features, mainly settlement pits, numerous pottery sherds and animal bones (post-consumption remains) were found. Pottery technology and decoration make possible to link these materials with the Note phase and date them back to 430CM1000 be.The article is aimed at presentation of a newly discovered  Linear Band Pottery settlement at Kościelna Jania, Smętowo Graniczne commune.

Environmental Laws in Nigeria and Occurrence of Some Geohazards: A Review

Nigeria as a country is blessed with an abundance of both human and natural resources. Exploitation of natural resources in Nigeria over the years with little or no regard for the environment has increased susceptibility of parts of the country to identified geohazards. A suite of environmental laws exist in Nigeria, all these aimed at protecting both the environment and its inhabitants. The aim of this paper is to review existing environmental laws in Nigeria, and occurrence of identified geohazards as a result of absence or non-implementation of these laws. Data for this study were obtained primarily from secondary sources. They are published government reports, journal articles, books, as well as other resources on the environment of Nigeria. Results show that Nigeria as a country has suitable existing and well-meaning environmental laws. The country also has many agencies charged with the responsibilities of implementing these environmental laws and policies. However, the non-implementation and non-existence of identified environmental laws and policies has increased both exposure and vulnerability of parts of the country to geohazards. The effects of these include; loss of means of livelihood, environmental degradation leading to Badlands in parts of the country, as well as death in extreme cases. It is recommended in this paper that adherence to existing environmental laws and policies as a panacea to mitigating identified geohzards is important. It is further recommended that amendment of already existing environmental laws to capture contemporary realities be made. This paper concluded by calling for more investment in the use of remote sensing and GIS tools such as LiDAR technology in the study of geohazards

Measuring output gap uncertainty

We propose a methodology for producing density forecasts for the output gap in real time using a large number of vector autoregessions in inflation and output gap measures. Density combination utilizes a linear mixture of experts framework to produce potentially non-Gaussian ensemble densities for the unobserved output gap. In our application, we show that data revisions alter substantially our probabilistic assessments of the output gap using a variety of output gap measures derived from univariate detrending filters. The resulting ensemble produces well-calibrated forecast densities for US inflation in real time, in contrast to those from simple univariate autoregressions which ignore the contribution of the output gap. Combining evidence from both linear trends and more flexible univariate detrending filters induces strong multi-modality in the predictive densities for the unobserved output gap. The peaks associated with these two detrending methodologies indicate output gaps of opposite sign for some observations, reflecting the pervasive nature of model uncertainty in our US data

Recent climate anomalies and their impact on snow chemistry at South Pole, 1987 - 1994

Three 2-m deep snowpits sampled at South Pole in 1994 provide detailed (2-cm resolution) profiles of the concentrations of soluble ionic species for the period 1987 - 1994. The most prominent feature is a large concentration spike of SO4 = in snow deposited in 1992 reflecting fallout from the eruptions of Pinatubo and Hudson in 1991. Concentrations of MSA and values of the MSA/(non-sea-salt SO4 =) ratio are elevated for about three years centered on the prominent volcanic signal. These changes appear to be due to the extended 1991 - 1993 El Nino. The overlapping effects of the volcanic eruptions and El Nino circulation preclude partitioning the enhanced deposition of SO4 = into volcanic and biogenic fractions. Nitrate concentration profiles show no relation to the severity of O3 depletion in the Antarctic stratosphere during the period of record. Rather, the profiles show a progressive decline of the annual peak concentrations over the top 0.5 - 1.0 m of each pit. This behavior is attributed to post-deposition loss of NO3 -, presumably by re-emission of HNO3 into the atmosphere. Copyright 1996 by the American Geophysical Union

Brief Communication: Intertooth and Intrafacet Dental Microwear Variation in an Archaeological Sample of Modern Humans From the Jordan Valley

Dental microwear was recorded in a Bronze-Iron Age (3570–3000 BP) sample of modern humans recovered from Tell es-Sa'idiyeh in the Jordan Valley. Microwear patterns were compared between mandibular molars, and between the upper and lower part of facet 9. The comparison revealed a greater frequency of pits and shorter scratches on the second and third molars, compared to the first. Pit frequency also increased on the lower part of the facet on the first molar, compared to the upper part. These results support previous calls for standardization when selecting a molar type for a diet-microwear study. Otherwise the microwear variations along the tooth row could mask any diet-microwear correlations. The results also suggest that there may be a need to choose a consistent location on a facet in order to enhance comparability among studies

Gorlin syndrome in a patient with skin type VI

Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome, is a rare autosomal dominant disorder that is characterized by multiple basal cell carcinomas developing at a young age, keratocystic odontogenic tumors of the jaw, palmar or plantar pits, calcification of the falx cerebri, and skeletal abnormalities. Nevoid basal cell carcinoma syndrome is caused by mutations in the PTCH1 or SUFU genes. Our patient with Fitzpatrick skin type VI was diagnosed with Gorlin syndrome based on the presentation of multiple major diagnostic characteristics. Although he is 33 years old, he has not developed any multiple basal cell carcinomas to date

A multidisciplinary study of an exceptional prehistoric waste dump in the mountainous inland of Calabria (Italy) : implications for reconstructions of prehistoric land use and vegetation in Southern Italy

The mountainous inland of northern Calabria (Southern Italy) is known for its sparse prehistoric human occupation. Nevertheless, a thorough multidisciplinary approach of field walking, geophysical survey and invasive research led to the discovery of a major archaeological archive. This archive concerns a rich multi-phased dump, spanning about 3000 years (Late Neolithic to Late Imperial Roman Age) and holding two Somma-Vesuvius tephra. Of these, the younger is a distinct layer of juvenile tephra from the Pompeii eruption, while the older concerns reworked tephra from the Bronze Age AP2 eruption (ca. 1700 cal. yr BP). The large dump contains abundant ceramics, faunal remains and charcoal, and most probably originated through long-continued deposition of waste in a former gully like system of depressions. This resulted in an inversed, mound-like relief, whose anthropogenic origin had not been recognized in earlier research. The tephras were found to be important markers that support the reconstruction of the occupational history of the site. The sequence of occupational phases is very similar to that observed in a recent palaeoecological study from nearby situated former lakes (Lago Forano/Fontana Manca). This suggests that this sequence reflects the more regional occupational history of Calabria, which goes back to ca. 3000 BC. Attention is paid to the potential link between this history and Holocene climatic phases, for which no indication was found. The history deviates strongly from histories deduced from the few, but major palaeorecords elsewhere in the inlands of Southern Italy (Lago Grande di Monticchio and Lago Trifoglietti). We conclude that major regional variation occurred in prehistoric land use and its impacts on the vegetation cover of Southern Italy, and studies of additional palaeoarchives are needed to unravel this complex history. Finally, shortcomings of archaeological predictive models are discussed and the advantages of truly integrated multidisciplinary research
