Use of past tenses in Venezuela (comparative study)
CHMELÍKOVÁ, Eva
The aim of this bachelor thesis is the comparison of the past tense in Venezuela. The thesis is divided into theoretical and practical part. The theoretical part is focused on the use of past tenses in Spanish language, the creation, characteristic and function in the territory of Spain and Latin America. At the same time are mentioned some linguistic phenomenon of two previous past tenses. There are two chapters in the practical part. The first chapter is focused on the frequency of prototypical adverbs in connection with past tense in Venezuelan literature and press. The analysis is performed using the CREA and CORPES XXI corpuses. The second chapter is about the frequency of presence of past tense on internet blogs in Venezuela which is worked up through the corpus Araneum Hispanicum Maius.

Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Separation Anxiety
Poživilová, Alena ; Fiala Šebková, Naděžda (advisor) ; Chmelíková, Eva (referee)
The purpose of the thesis was to develop a scientific review, as comprehensive as possible, of literature on separation anxiety in dogs. Separation anxiety is one of the most common behavioral disorders in domestic dogs. The thesis is of compilation nature. First, separation anxiety is described and explained as an independent concept in problematic behaviour of dogs. Further, the incidence and frequency of this behavioral disorder in the dog population are described, including risk factors that precede the onset of this behavioral disorder. Many risk factors exist, which are described in detail in the thesis. Both main and secondary symptoms are described; excretion, destructiveness, hypersalivation, and vocalization. The thesis also includes a chapter on the diagnosis of separation anxiety. This chapter describes how to proceed in an effort to remedy separation anxiety, and what the owner should arrange, what he/she should be attentive to and take care of. Prevention is discussed in the subsequent chapter. The final part of the review is focused on the therapy of separation anxiety. Possible therapies include behavioral desensitisation, modification of the behaviour, and reduction of dependence on the owner. For the therapy to be as efficient as possible, pharmacotherapy is recommended. The thesis describes treatment with clomipramine, potassium clorazepate in combination with fluoxetine, fluoxetine and diazepam. However, it is more advisable to prevent separation anxiety by the very choice of a suitable dog (characteristics of the individual, its temperament, and the breed), and by responsible education on part of the owner.

The role of immune cells in tumor growth and spontaneous regression in a rat sarcoma model
Kovalská, Jana ; Chmelíková, Eva (advisor) ; Anna, Anna (referee)
The aim of the thesis is to study differences between sexes of rats in tumour growth, the difference in immune response between rats with progressing and spontaneously regressing tumours compared to control rats and verification of immunological memory. We used Lewis rat model with subcutaneously inoculated sarcoma. Peripheral blood of males showed a higher number of red blood cells, a higher concentration of haemoglobin and higher haematocrit compared to females. Experimental females with inoculated sarcoma had higher levels of CD161 (NK) cells at the beginning of experiment in comparison with the experimental and control males and control females. A strong infiltration of NK cells was observed in tissue sections of spontaneously regressing sarcoma compared to progressing tumours tissue. Important factors that can influence if the animal will show tumour progression or spontaneous regression are neutrophil granulocytes (they can induce both tumour-supporting and anti-tumour response), vascularization and extent of necrosis in tumour tissue. We have verified immunological memory in a small group of females by the secondary inoculations of the same tumour cells after complete disappearance of primary, spontaneously regressing tumour. No sarcoma repeatedly evolved in any of the females. Results obtained in the present work brought new insights into the problems of tumour in the Lewis rat sarcoma model with inoculated sarcoma. These results may have significance also for area of clinical oncology due to similarities with the behaviour of some human cancers.

Bitchs pregnancy and aftercare about bitch and her puppies
Šírková, Eliška ; Chmelíková, Eva (advisor) ; Fiala Šebková, Naděžda (referee)
The period from the beginning of rutting, mating, pregnancy to birth and following birth time is a difficult period for the whole female dogs organism. The reproductive activity of a female dog is characteristic by physiological, ethological and somatic changes corresponding to each stage of this period. After setting of suitable time of mating, the progesteron level is detected by sampling of peripheral blood. Possible is also assessment of number of foetus by X-ray in time when puppies have ossified bones. Both of these methods can prove not only frequency of litters but also possible complications from side of mother or puppy.
The hormonal activity is an important part of genitals during the pregnancy. Their activity and central control are an important factor for a normal development of a foetus and for a physiological birth.
Some complications can happen during the birth because of the material or fetal causes. Material causes occur more than fetal ones and the most frequent complication is lack of contraction of the uterine muscles or the narrow pelvis. Fetal causes are less frequent but they are more serious. It can occur to wrong posture of a puppy in birth canals or a foetus can be abnormal big.

Problematic behaviour in shelter dogs
Kubíková, Kateřina ; Fiala Šebková, Naděžda (advisor) ; Chmelíková, Eva (referee)
The aim was to create the most comprehensive scientific literature review on the topic of problematic dog behavior in the shelters.
The work defines physiological and psychological needs of the dog and its natural behavior. There is described the influence of stress, most frequented causes and consequences and different types of behavior problems, which we can meet in dogshelters. Further are the factors that influence the behavior of the dog in the shelter, and the factors that increase the chance of a dog to be adopted. This chapter describes the issue of overpopulation of dogs in the world and castration and sterilization programs to control animal population.
The next part deals with the possible problems that may occur after the dog is adopted by new owner, especially if the owner already have other dogs or children.
The final part of the review focuses on euthanasia, which is compared to the situation in the Czech Republic and abroad.
Problems that may occur after the adoption of a dog from a shelter can be prevented by choosing a suitable dog due of the physical and time schedule of the owner and his experiences with dogs.
