In this report, we examine the unsteady Stokes equations with nonhomogeneous boundary conditions. As an application of a Carleman estimate, we first establish log type stabilities for the solution of the equations from either an interior measurement of the velocity, or a boundary observation depending on the trace of the velocity and of the Cauchy stress tensor measurements on a part of the boundary.

The ichneumonid parasitoid Stenarella insidiator (Smith, 1859) is recorded for the first time from Vietnam based on the specimens collected from Tam Dao National Park in Vinh Phuc province, Na Hang district in Tuyen Quang province, and Bidoup-Nui Ba National Park in Lam Dong province. In addition, the wasp Orancistrocerus aterrimus (de Saussure, 1852) (Hymenoptera: Vespidae) is reported as a new host of this parasitoid. The parasitoid is described based on Vietnamese material with information of its overwintering in the wasp nest.

Melanotic neuroectodermal tumour of infancy (MNTI) is a rare, pigmented neoplasm generally arising in infants during the first year of life. The tumor is rapidly growing, pigmented neoplasm of neural crest origin. The mean age of patients at diagnosis is 4.3 months, with a near-equal male to female ratio of 6:7.

Primary and secondary reconstruction of the thumb is a common reconstructive challenge for the hand and plastic surgeons. Currently, The kite flap or the First dorsal metacarpal artery flap remains the regular choice and is believed to be the best for distal thumb defects, but it’s the first time we have utilized a reverse homodigital dorsal radial flap for the thumb with an expected outcome.

In the present report, a novel concept of frequency response function (FRF) is introduced for piezoelectric beam. First, a model of Timoshenko beam bonded with a piezoelectric layer is established and used for deriving the conventional frequency response function acknowledged as mechanical frequency response function (MERF). Then, the output charge produced in the piezoelectric layer is calculated from the MFRF and therefore obtained frequency-dependent function is called electrical frequency response function (EFRF) for the integrated beam.

From CHCl3-soluble extract of the leaves of Taxus wallichiana (Taxaceae), collected in Lam Dong Province, five compounds were isolated and identified as sciadopitysin, ginkgetin, (S)-(+)-rhododenol, (+)-erythro-N-benzoyl3-phenylisoserine methyl ester, and (−)-α-conidendrin (5). Their chemical structures were determined by 1D and 2D NMR spectra and comparison with published data. Except for (−)-α-conidendrin, these remaining compounds were first reported of Taxus wallichiana.

The molecular data of D2-D3 of 28S rRNA region, morphometrics, and morphological features of second-stage juveniles, males, and females in the present study have confirmed that the root-knot nematode recovered from pomelo in Vietnam belongs to M. enterolobii. To the best of our knowledge, this represents the first report of M. enterolobii infecting pomelo, providing new insight into the host status of this important pest.

The present work provides a taxonomic key to the genera of Polygonaceae found in Vietnam. It also reports the first occurrence of Persicaria runcinata in Lai Chau province, extending its known distribution within the country. Detailed photographic illustrations of the specimens studied accompany the findings. This extended distribution of P. runcinata could hold significant conservation implications, emphasizing the importance of further research and conservation efforts in the region.

The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.

This thesis examines the strategic and potentially legitimising nature of voluntary environmental reporting. First, the thesis examines the relationship between emission levels on the National Pollutant Inventory and the quantity of total voluntary environmental disclosures, voluntary emission disclosures and positive voluntary environmental disclosures in annual reports. Second, an examination of changes in the quantity of disclosures discussing compliance with the National Pollutant Inventory and/or disclosures concerning pollution emissions is undertaken.

Knowledge of the Late Paleozoic sedimentary history of the northern Gondwana shelf is advanced by new data from the Şort Dere section (Hakkari Basin). Early Carboniferous myalinid bivalves from the Middle East are reported here for the first time. The pre-Permian basement of the Hakkari Basin consists of a Lower Carboniferous sedimentary sequence including the Köprülü and Belek formations. The Köprülü Formation has yielded rich assemblages of vertebrates and invertebrates. Hitherto myalinid bivalves were unknown from this formation.
