The article considers the historical and cultural heritage of villages of the former Ketskaya volost, which is currently a part of the Tomsk region. The formation of Ketsky prison and the architecture of large settlements of the former Ketskaya volost are studied. Little is known about the historical and cultural heritage of villages of the Tomsk region and the problems of preserving historical settlements of the country.The aim of this work is to study the formation and development of the village architecture of the former Ketskaya volost, currently included in the Tomsk region.The following scientific methods are used: a critical analysis of the literature, comparative architectural analysis and systems analysis of information, creative synthesis of the findings. The obtained results can be used in preparation of lectures, reports and communication on the history of the Siberian architecture.The scientific novelty is a study of the historical and cultural heritage of large settlements of the former Ketskaya volost, which has not been studied and published before. The methodological and theoretical basis of the study is theoretical works of historians and architects regarding the issue under study as well as the previous author’s work in the field.It is found that the historical and cultural heritage of the villages of the former Ketskaya volost has a rich history. Old historical buildings, including religious ones are preserved in villages of Togur and Novoilinka. The urban planning of the villages reflects the design and construction principles of the 18th century. The rich natural environment gives this area a special touch.

Respiratory system cancer (cancer of the nasal cavity, middle ear, paranasal sinuses (C30-31), larynx (C32), trachea, bronchi and lung (C33-34) is one of the most common malignancies in the Tomsk region, comprising 12.9% of all cancer cases. The purpose of the study was to analyze the respiratory system cancer incidence among the population of the Tomsk region. Materials and methods. The study was based on cancer register data collected at the Cancer Research Institute and Tomsk Regional Cancer Center, and covered the period 2005-2016. Results. Respiratory system cancer is the most common cancer in men, comprising 21.7% and the 6-th most common cancer in women, comprising 5.1. The incidence of respiratory system cancer decreased in men and showed an increasing tendency in women. The age-standardized incidence rates in the Tomsk region were expected to be 58.3 per 100,000 males and 12.8 per 100,000 females by 2020. Conclusion. Early detection and prediction of respiratory system cancer should play a vital role in the diagnosis process and also increase the survival rate of patient.

Different Levels

The aim of this work was to assess the possible impacts on the forest soil and stand due to silvicultural treatment and forest operations in a beech high forest. Even aged beech forests (Fagus sylvatica L.) in the Municipality of Cappadocia (L’Aquila) and in the Municipality of Vallepietra (Roma) were analyzed. The analysis of the soil and stand were performed in order to assess the effects attributable to applied silviculture and forest logging. Two different logging methodologies (in particular for the extraction) were applied: mules were used in the areas with greater slopes and with obstacles, while for the areas with better accessibility, mechanical means were used, in this case tractors. In detail, the main objective was to assess the disturbance on the ground and on the stand, generated by the two different levels of mechanization. In addition, it was also interesting to understand the possible effect on the soil and specifically on the partial uncovering where part of the tree canopy was removed. Only through an accurate cross-analysis of the studied parameters and indices could the anthropogenic impacts on the soil and stand due to forest operations be highlighted according to the different logging methodologies applied. The main results showed that the disturbances caused to the soil and stand were essentially caused in the bunching and extraction operations. The importance of avoiding or limiting the continuous passage of vehicles and animals on forest soil clearly emerges, especially in conditions of high soil moisture. It is also important to use correct technologies that are adequate for the specific environmental characteristics and the work plan. Finally, it can be said that there was no difference in the disturbance caused by the two logging methods when compared. Substantial differences in terms of improvement can be defined when comparing the findings of this study with other research studies. This can be done by applying a different type of mechanization with a different logging system.

Soil Recovery

Engineering applications can be used to mitigate the adverse effects of soil compaction and amend compacted soils. Previous literature has highlighted the beneficial effects of interventions such as litter mulching and incorporation on skid trails. However, little is known about the effectiveness of these alternatives in restoring forest soil quality after forest logging. The objective of this study was to properly elucidate the effects of the above mentioned soil protection methods, litter incorporation before skidding (LI) and litter mulching after skidding (LM), on the recovery of compacted soil’s physico-chemical and biological properties on skid trails over a 2-year period in the Hyrcanian forests of Iran to identify the best option for restoration intervention. The litter used in both methods consisted of dried leaves of the hornbeam and maple tree in three intensities of 3, 6, and 9 Mg ha−1. The results showed that the application of both methods (LI and LM) significantly improved the soil properties when compared to the untreated skid trail. Results showed that the recovery values of soil properties in the LI treatments were significantly higher than those of the LM. The recovery values of soil properties by 6 and 9 Mg ha−1 were significantly higher than those of 3 Mg ha−1, while the differences were not significant between 6 and 9 Mg ha−1. Our findings showed that soil properties were partially recovered (70–80%) over a 2-year period from treatment, compared to untreated, but the full recovery of soil properties required more time to return to the pre-harvest value. Overall, the results of this study demonstrated that the application of soil protection methods accelerates the process of recovering soil properties much faster than natural soil recovery, which can take more than 20 years in these forests.
