Augavietės poveikis paprastosios kiaulpienės (Taraxacum officinale F. H. Wigg.) anatominei ir morfologinei sandarai / The influence of habitat on the anatomical and morphological structure of common dandelion (Taraxacum officinale F. H. Wigg.)

Zverkova, Julija 04 June 2005 (has links)
In this work habitats impact to dandelion´s anatomic and morphologic state. Dandelion´s leaf is dorsoventral, bifaciral type. Mesophyll habitat epidermal cells are izodeometric, waved, whereas in the higrophyll – slightly waved and extended in tangential direction. Mesophyll habitat epidermal cells´ number is bigger than in the higrophyll. In the mesophyll habitat on the upper epidermal cells´ number is 85,4, on the lower – 87,2 per 1 mm², accordingly in the higrophyll habitat – 79,3 and 82,4 per 1 mm². Stomata apparatus per 1mm² are more in the higrophyll habitat (on the upper lamina´s side there were 20,2, on the lower – 24,9 stomata apparatus), than in the mesophyll (on the upper lamina´s side there were 14,8, on the lowe – 19,5 stomata apparatus). In the mesophyll habitat upper lamina´s side stomata´s coefficient was 19,36% and 45,57%. Dandelion´s leafstalk is ivugularly – shaped trapezium. In the mesophyll habitat – double, in the higrophyll – single, air spaces´ diameter – 1056 ��. In the lamina´s epidermis the stomata apparatus is not found neither on the upper, nor on the lower side. Dandelion´s leafstalk is represented by tabular collenchyma. In the leafstalk´s parenchyma articulate communicating latex vessel are situated. Investigated on the Taraxacum officinale, wich is growing in the mesophyll and higrophyll habitats, anatomic state of radix is definited that changing habitat the anatomic state of radix shifts a little bit. Independent of habitat radix is... [to full text]

Kriminalistinė homoskopinių pėdsakų charakteristika ir tyrimo galimybės / Characteristics of homoscopic traces and possibilities of their investigation from the point of view of forensics

Gargasaitė, Akvilė 25 June 2014 (has links)
Šiame magistro baigiamajame darbe nagrinėta pakankamai nauja tema ,,Kriminalistinė homoskopinių pėdsakų charakteristika ir tyrimo galimybės“, kadangi Lietuvos kriminalistinėje literatūroje nėra aptinkamos tokios sąvokos kaip homoskopinis pėdsakas, nors yra mokslinių darbų, kuriuose tas pats pėdsakas vadinamas homeoskopiniu. Homoskopiniai pėdsakai yra žmogaus kūno dalimi palikti pėdsakai, kurie skirstomi į rankų, kojų (basų kojų pėdsakai, kartais randami ir avalynės viduje), dantų, nagų ir galvos paviršiaus pėdsakus. Pirmoje darbo dalyje trumpai išdėstyta, kas yra pėdsakai nagrinėjamos temos prasme bei pėdsakų rūšys. Vėliau aptariama kiekviena iš homoskopinių pėdsakų rūšių anatomiškai bei kriminalistiniu požiūriu – pateikiama pėdsakų charakteristika. Rankų pėdsakai yra dažniausiai aptinkami, tiriami bei pagal juos lengviausia identifikuoti asmenį, todėl jie yra aptarti pirmiausiai. Toliau yra pateikiamos kojų, dantų, nagų bei galvos paviršiaus (svarbiausias vaidmuo tenka lūpų bei ausų pėdsakams) pėdsakų charakteristikos. Pagal juos taip pat galima nustatyti asmens tapatybę, tačiau tai padaryti yra sunkiau nei rankų pėdsakų atveju. Kita vertus, gali būti nustatyta daug informacijos apie atskiras nusikalstamos veikos aplinkybes. Antroje darbo dalyje nurodyta, kokiose įstaigose Lietuvoje yra atliekami specialisto tyrimai bei ekspertizės. Be to, pateiktos homoskopinių pėdsakų tyrimo galimybės surandant, išryškinant, fiksuojant, paimant bei tiriant laboratoriniu būdu homoskopinius... [toliau žr. visą tekstą] / A quite new subject “Characteristics of Homoscopic Traces and Possibilities of their Investigation from the Point of View of Forensics” was analyzed in this master’s thesis, whereas it cannot be found such a concept as homoscopic trace, although there is some scientific work in which the same trace is called homeoscopic. Homoscopic traces are the ones that are left by human body parts and they are divided into handprints, footprints (barefoot and footprints in footwear), bite marks, fingernail scrapings and prints that are left by a surface of a head. The first part briefly sets out what is the meaning of the traces and their types within the topic of the thesis. Also each kind of the homoscopic traces are discussed anatomically and from the point of view of forensics, thus the characteristics of homoscopic traces are given. At first handprints are discussed because they are mostly detected and examined. Furthermore by using them it is easy to identify a person. Then the characteristics of footprints, bite marks, fingernail scrapings and prints left by a surface of a head (especially lip prints and ear prints) are represented. Using them we can also determine person’s identity but it is more difficult than using handprints. On the other hand, we can learn some information about individual circumstances of the crime. The institutions in Lithuania in which specialists’ researches and forensics are carried out are noted in the second part of master’s thesis. In addition, the... [to full text]
