Expert knowledge based approach for automatic sorting and packing
The automatic sorting system is presented in this work which is based on expert knowledge and high resolution visual sensor. Proposed system was tested for natural amber sorting task. Five types of amber have been explored in this research. Experimental investigation involves amber classification in three different color spaces (RGB, HSV and Grayscale). The results have shown that the highest classification accuracy is reached using the combination of the most essential features sets acquired from different color spaces
Morphological and genetic diversity of European cranberry (Vaccinium oxycoccos L., Ericaceae) clones in Lithuanian reserves
The wild-harvested fruit of Vaccinium oxycoccos (European cranberry) is used medicinally in many European and North American countries; the plant, however, is seldom cultivated. In order to optimize the collection strategy and improve the horticulturally important characters of V. oxycoccos clones, comprehensive investigations of the species are necessary. In the present study we investigated the phenological, morphological and genetic diversity of 29 clones originating from two wild populations growing in two strictly protected Lithuanian reserves, Čepkeliai and Žuvintas. During an ex situ collection at Kaunas Botanical Garden, we observed great phenological variation between the collected V. oxycoccos clones. The following morphological traits most clearly distinguished our study clones: leaf size, berry shape, berry size and fruit colour at full maturity. The genetic variation of V. oxycoccos clones from the two populations was assessed using RAPD and SSR. RAPD analysis conducted with 9 primers resulted in 146 polymorphic loci for the total sample, and SSR analysis with 5 primers revealed 29 alleles for the total sample. A greater degree of polymorphism was demonstrated for the Čepkeliai population than for the Žuvintas population. The study allowed the selection of several clones having promising morphological traits for further testing in the field
St. Ignatius of Antioch and Afua Kuma of Kwahu : a study in some images of Jesus in second century Christianity and modern African Christianity.
Thesis (M.Th.)-University of Natal, Pietermaritzburg, 2000.Christian religious experience whether it occurs in the second century or in modem Africa is one and the same, and although the experiences may differ it is possible to draw correlations to suggest that such experiences bear witness to a common reality. St. Ignatius of Antioch who lived in the second century and Afua Kuma who hails from Kwahu in the Eastern Region of Ghana, are used to demonstrate this reality. My sources for Ignatius' are the seven letters he wrote, six to churches he visited and one to his friend Polycarp of Smyrna, whilst he was on his way to martyrdom in Rome. As bishop of Antioch he is concerned about the unity of the church and consequently focuses attention on false doctrines and the development of what was becoming "orthodox" tradition. A number of peculiar images referring to Christ emerge in his work, such"as apXEta (archive), 8upa (door), xapaK1"rlp (stamp) and 8t)(:nacr'trlpwv (altar). This picturesque and vivid imagery is traced to his propensity for rhetoric, which, though Asian, bears resemblance to the Greek and Roman folkloric traditions. The Apae or the courthouse praise poetry of the Akan folkloric tradition is the vehicle that Afua Kuma employs to express her faith in Jesus. A crisis in Madam Kuma's life must have led her to fathom the depths of her traditional background and upbringing and this she feeds into her understanding of Jesus. In her poetry Jesus is imaged as Adontehene, Benkumhene, :Jkatakyie, :Jkokodurufo, Okuruakwaban, and Adubasap::m and is made to perform all the functions associated with regal authority. She also shows awareness of modem political and social structures in these images. This thesis shows that it is the fruit of the Christian imagination born in the context of praise and worship, which ought to feed and nourish academic theology so as to keep it in touch with the spiritual vitality experienced in the community of faith

Epidemiology of Lyme Disease in a Highly Endemic European Zone
Background and objective: Lyme disease, also known as Lyme borreliosis (LB), is a tick-borne infectious disease caused by the spirochete bacteria Borrelia. The risk of infection depends on the geographical area, ecological factors, and human behavior. Clinical manifestations of Lyme borreliosis have a wide range, but the most frequent clinical symptom, which is also a diagnostic symptom, is a skin rash called erythema migrans (EM). The disease is very common worldwide. In Lithuania, the disease frequency is 99.9 cases per 100,000 population (Centre for Communicable Diseases and AIDS, Lithuania, 2017). The main aim of this study was to obtain the baseline characteristics of the disease regarding the infected Lithuanian population. Materials and Methods: We analyzed data from the Centre for Communicable Diseases and AIDS about all Lyme disease (A69.2) diagnosed patients over a three-year period (from 2014 to 2016) in Lithuania. Results: In 2014–2016, 7424 (crude incidence rate 85.4) cases with LB were diagnosed in Lithuania. Most of them (4633 (62.4%)) were identified in women. Older people were more likely to suffer from LB. Urban residents were 2.6 times more often affected that those living in villages. Tick bites were primarily observed in high season months, from May to September (90%), with the highest peak in July. There was a higher number of observed tick bites (p = 0.003) in the urban residents. Erythema migrans occurred in 75.6% LB cases, while other symptoms did not exceed a quarter of all LB cases. There were 7353 (99.6%) cases where LB was confirmed via clinical symptoms and/or laboratory tests. Also, 1720 (23.2%) patients were tested for LB immunoglobulins. Conclusions: This study found a high incidence of Lyme disease in Lithuania. We elucidated the baseline characteristics regarding the infected Lithuanian population which may ease medical clinicians’ work on new Lyme diagnoses
Babesiosis in Southeastern, Central and Northeastern Europe: An Emerging and Re-Emerging Tick-Borne Disease of Humans and Animals
There is now considerable evidence that in Europe, babesiosis is an emerging infectious disease, with some of the causative species spreading as a consequence of the increasing range of their tick vector hosts. In this review, we summarize both the historic records and recent findings on the occurrence and incidence of babesiosis in 20 European countries located in southeastern Europe (Bosnia and Herzegovina, Croatia, and Serbia), central Europe (Austria, the Czech Republic, Germany, Hungary, Luxembourg, Poland, Slovakia, Slovenia, and Switzerland), and northern and northeastern Europe (Lithuania, Latvia, Estonia, Iceland, Denmark, Finland, Sweden, and Norway), identified in humans and selected species of domesticated animals (cats, dogs, horses, and cattle). Recorded cases of human babesiosis are still rare, but their number is expected to rise in the coming years. This is because of the widespread and longer seasonal activity of Ixodes ricinus as a result of climate change and because of the more extensive use of better molecular diagnostic methods. Bovine babesiosis has a re-emerging potential because of the likely loss of herd immunity, while canine babesiosis is rapidly expanding in central and northeastern Europe, its occurrence correlating with the rapid, successful expansion of the ornate dog tick (Dermacentor reticulatus) populations in Europe. Taken together, our analysis of the available reports shows clear evidence of an increasing annual incidence of babesiosis across Europe in both humans and animals that is changing in line with similar increases in the incidence of other tick-borne diseases. This situation is of major concern, and we recommend more extensive and frequent, standardized monitoring using a “One Health” approach
Large-scale mitochondrial DNA analysis reveals new light on the phylogeography of Central and Eastern-European Brown hare (Lepus europaeus Pallas, 1778)
European brown hare, Lepus europaeus, from Central and Eastern European countries (Hungary, Poland, Serbia, Lithuania, Romania, Georgia and Italy) were sampled, and phylogenetic analyses were carried out on two datasets: 1.) 137 sequences (358 bp) of control region mtDNA; and 2.) 105 sequences of a concatenated fragment (916 bp), including the cytochrome b, tRNA-Thr, tRNA-Pro and control region mitochondrial DNA. Our sequences were aligned with additional brown hare sequences from GenBank. A total of 52 and 51 haplotypes were detected within the two datasets, respectively, and assigned to two previously described major lineages: Anatolian/Middle Eastern (AME) and European (EUR). Furthermore, the European lineage was divided into two subclades including South Eastern European (SEE) and Central European (CE). Sympatric distribution of the lineages of the brown hare in South-Eastern and Eastern Europe revealed contact zones there. BAPS analysis assigned sequences from L. europaeus to five genetic clusters, whereas CE individuals were assigned to only one cluster, and AME and SEE sequences were each assigned to two clusters. Our findings uncover numerous novel haplotypes of Anatolian/Middle Eastern brown hare outside their main range, as evidence for the combined influence of Late Pleistocene climatic fluctuations and anthropogenic activities in shaping the phylogeographic structure of the species. Our results support the hypothesis of a postglacial brown hare expansion from Anatolia and the Balkan Peninsula to Central and Eastern Europe, and suggest some slight introgression of individual haplotypes from L. timidus to L. europaeus
Pan‐European phylogeography of the European roe deer (Capreolus capreolus)
To provide the most comprehensive picture of species phylogeny and phylogeography of European roe deer (Capreolus capreolus), we analyzed mtDNA control region (610 bp) of 1469 samples of roe deer from Central and Eastern Europe and included into the analyses additional 1541 mtDNA sequences from GenBank from other regions of the continent. We detected two mtDNA lineages of the species: European and Siberian (an introgression of C. pygargus mtDNA into C. capreolus). The Siberian lineage was most frequent in the eastern part of the continent and declined toward Central Europe. The European lineage contained three clades (Central, Eastern, and Western) composed of several haplogroups, many of which were separated in space. The Western clade appeared to have a discontinuous range from Portugal to Russia. Most of the haplogroups in the Central and the Eastern clades were under expansion during the Weichselian glacial period before the Last Glacial Maximum (LGM), while the expansion time of the Western clade overlapped with the Eemian interglacial. The high genetic diversity of extant roe deer is the result of their survival during the LGM probably in a large, contiguous range spanning from the Iberian Peninsula to the Caucasus Mts and in two northern refugia.202
