title: Sfruttamento e gestione delle risorse animali a Muro Leccese (Lecce): aspetti economici e sociali

description: La ricerca archeologica a Muro Leccese è stata avviata nel 1999 quando, in occasione del restauro del Palazzo del Principe, gli scavi archeologici hanno sin da subito messo in risalto le potenzialità del centro storico, tanto da ritenere imprescindibile la valorizzazione e la tutela di questo patrimonio culturale. Muro Leccese fornisce utili informazioni per comprendere le dinamiche storiche del Salento tra Medioevo e Rinascimento (XVI-XVII secolo d.C.), momento in cui in questo territorio vi era una pericolosa minaccia rappresentata dall'invasione turca. L'obiettivo preposto di questo lavoro è quello di ricavare informazioni sulla gestione delle risorse animali da parte dei contadini del Borgo, cercare di comprendere anche che tipo di alimentazione avessero, confrontando le loro consuetudini alimentari con quelle della famiglia nobiliare che risiedeva nel Palazzo del Principe. Dallo studio emerge che la dieta degli abitanti di "Borgo Terra" fosse basata prevalentemente sul consumo delle quattro principali specie domestiche, mentre la caccia e la pesca non ricoprirono un ruolo rilevante nell'economia; al contrario, nel Palazzo sono stati recuperati diversi resti di pesci e molluschi di ottima qualità.
description: The archaeological research at Muro Leccese started in 1999 when the University of Salento was invited to participate in the restoration of the Prince's Palace. The archaeological excavations immediately brought into evidence the potentials of the Old Town and therefore the importance to promote and protect that particular cultural heritage. Muro Leccese delivers useful information for the understanding of historical dynamics in the region between the Middle Ages and the Renaissance (16th-17th c. AD), a period marked by the dangerous threat of the Turkish invasion. The designated target of this work is to obtain information on the management of animal resource by the farmers of the village (Borgo Terra), in order to understand the diet they followed, as well as to confront their diet with those of the noble family that resided at the Prince's Palace. The study shows that the diet of the inhabitants of Borgo Terra was based mainly on the four major domestic species, while hunting and fishing did not play an important role in the economy. Alternatively, various remains of fish and shellfish of excellent quality were found within the compounds of the Palace.

title: Semi-continuous production of biodiesel from palm fatty acid using novozym 435

description: Production of biodiesel from palm fatty acid, which was a by-product from refining palm oil production, was investigated semi-continuous process catalyzed by Novozym 435. It was found that, using tert-butanol as a cosolvent could maintain activity of lipase even high amount of methanol was present in the system and could improve yield of fatty acid methyl ester (FAME). A molar ratio of palm fatty acid and methanol, tert-butanol quantity and flow rate had significant effects on the percent molar conversion in semi-continuous process. The appropriate conditions for synthesis were as follows: reaction temperature 50℃, flow rate 1.87 mg/sec, and methanol to palm fatty acid ratio 2:1 and tert-butanol 29% based on palm fatty acid weight. One-step and three-step process were investigated. The highest conversion ratio of the FAME from one-step and three-step under the optimal condition was 80% and 92%, respectively. The lipase catalyst could be used for &gt; 240 hours without decrease of the activity.

title: Digital-camera captured image restoration by using spline-based dewarping function and deshading function based on polynomial-logarithm

description: This paper proposes a novel dewarping and deshading technique for digital camera based document images, from which images are warped on the curve surface of the book bound volume. Our dewarping technique by using look-up table transforms pixels on the curve coordinate system into the planar coordinate system. In the deshading method, the shade on the image is removed by using Least Square Error method (LSE). Our technique is independent on document contents, page layout, and font styles. In the experiments, the test document images composed various font styles and sizes printed in common text books. The validity of our methods is compared with the program’s curvature correction of Abby FineReader Professional 9.0 and Omnipage professional 16. Our technique outperforms the Abby’s curvature correction up to 49 percent and the OmniPage’s curvature correction up to 10 percent for word and character precisions.

title: Health risk assessment for people in Ronphibun district, Nakhon Si Thammarat province from exposure to arsenic

description: The purposes of the study were to determine the amount of soil ingested by Thai people and to conduct a risk assessment of people residing in Ronphibun district from consuming the arsenic contaminated food by duplicate meal method and soil ingestion pathway. Soil ingestions in Thai people were studied in both children and adults by using aluminum (Al), silicon (Si), and yttrium (Y) as trace elements. A mass balance approach was employed to assess daily soil ingestion. Duplicate samples of foods and beverages, feces, and urine were collected for 7 consecutive days. The amounts of tracer elements in samples were analyzed using inductively coupled plasma-atomic emission spectrometry (ICP-AES). In children, an average and the 95th percentile of soil ingestion based on Al were 29.88 and 190.94 mg/d, based on Si were 36.33 and 173.35 mg/d, and based on Y were 30.05 and 157.38 mg/d (n = 70). In adults, the average and the 95th percentile of soil ingestion based on Al were 27.16 and 106.7 mg/d, based on Si were 22.53 and 127.39 mg/d, and based on Y were 23.47 and 114.77 mg/d (n = 70). The recommended mean and the upper percentile of soil ingestion for Thai children were 50 and 175 mg/d and Thai adults were 35 and 120 mg/d, respectively. Both point and probabilistic risk assessment were used to estimate risk of ingested arsenic from soil in Ronphibun. Soil samples were taken from a land located in area and determined of arsenic concentration by hydride generation-atomic absorption spectrometry (HG-AAS) (n = 59). Hazard quotients were 0.32 - 5.46 in children and 0.38 – 9.0 in adults. The ranges of cancer risk from exposed to arsenic in soil were 4.14 x 10-6 - 1.4 x 10-4 in children and 1.25 x 10-5 - 3.7 x 10-4 in adults. Exposure to arsenic from food and water in adults was investigated by using 7 consecutive days duplicate meal samples collection from Ronphibun residents (n = 112). Inorganic arsenic concentrations are determined by HG-AAS. The ranges of total cancer risk were 7.25 x 10-4 - 3.97 x 10-3. Hazard index ranged from 3.16 – 13.24. The averages of contributions to risk from and soil pathway were found to be 88% and 12%, respectively. Sensitivity analysis indicated that most influential of risk were exposure duration and arsenic concentration in meal. In conclusion, risk values for people in Ronphibun district from exposure to arsenic exceeded the risk level of concern.

title: Selective oxidation of benzene over titanium-silica based catalyst

description: The selective oxidation of benzene to phenol using hydrogen peroxide as an oxidant was studied over the titanium-silica based catalyst such as Ti-MCM-41, TS-1 and TS-PQTM (the trade mark of PQ Corporation). These catalysts have been characterized using various techniques such as XRD, BET, DRUV-Vis, FT-IR and SEM. Under the preliminary studied conditions, TS-PQTM exhibited the highest catalytic activity among the studied catalysts. These findings can be correlated to enlarged BET surface, larger pore volume and higher amount of mesopores in the material as well as defects of the catalyst structure. The effects of pressure, H2O2 addition rate, reaction temperature, stirring speed, molar ratio of benzene/H2O2, volume of additional water and catalyst weight, on the catalytic performance of TS-PQTM were investigated. Under mild conditions, such as 70C and atmospheric pressure, an excellent overall phenol yield could be achieved over TS-PQTM.

title: Quantification and determination of antagonistic activity of bifidobacteria and lactobacilli in faeces of breast-fed and mixed-fed infants

description: This study aimed to determine the effect of feeding method on the quantity of bifidobacteria and lactobacilli in infants and investigate the antagonistic of these bacteria against enteric pathogens such as enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC), enteropathogenic E. coli (EPEC), enterohemorrhagic E. coli (EHEC), Salmonella Typhimurium, Shigella flexneri and Vibrio cholerae. The bifidobacteria and lactobacilli counts were compared between the 30 exclusively breast-fed and 33 mixed-fed infants (infants who received breast milk and formula milk) by real-time, quantitative PCR assays. The number of bifidobacteria in breast-fed and mixed-fed infants (mean values 8.26 and 8.42 log16S rRNA genes/g wet weight faeces, respectively; p = 0.67) and lactobacilli in these two groups (mean values 6.84 and 7.20 log16S rRNA genes/g wet weight faeces, respectively; p = 0.14) were not significantly different. One hundred and eleven Bifidobacterium and 39 Lactobacillus isolates from infants faeces were tested for their antagonistic activities against seven gastrointestinal pathogens by agar spot method. One hundred and six isolates of bifidobacterium had inhibitory activities. Interestingly, 10 Bifidobacterium isolates demonstrated strong antagonistic activities with clear zones against V. cholerae and Sh. Flexneri and weak activities against EHEC, EPEC, ETEC, EIEC and S. Typhimurium. Fourteen isolates of Lactobacillus had inhibitory activities, 7 isolates demonstrated weak antagonistic activities against V. cholerae with small clear zone. Genotypic identification by DNA sequencing demonstrated that the Bifidobacterium and Lactobacillus species in faeces of Thai infants at the age of one month included B. longum, B. bifidum, B. adolescentis, B. pseudocatenulatum, L. gasseri, L. salivarius, L.fermentum, L. ruminis, L. mucosae, L. vaginalis, L. oris, L. rhamnosus และ L. casei, respectively. Breast feeding and mixed feeding did not have effect on the number of bifidobacteria and lactobacilli in Thai infants. Bifidobacterium isolates possessed stronger antagonistic activities than Lactobacillus isolates in term of the varities of inhibited enteric pathogens and the magnitude of inhibition. Bifidobacterium isolates with the most potent antagonistic activities 90% DNA similarity with the most matched B. adolescentis. This indicated that these isolates might be new strains or new species and thus the potential sources of novel probiotic strains.

title: Parkes observations for project P1007 semester 2019APRS_07

description: Recently, extreme plasma lensing of pulsar emission has been observed in two eclipsing binaries, PSR B1957+20 and PSR B1744-24A. These lensing events are an extremely sensitive probe of pulsar emission, resolving physical scales of ~10 km at the pulsar, and can be used to measure the magnetization of the intrabinary material, and constrain outflow velocities and mass-loss rates of the binaries. We propose to observe the 5 brightest eclipsing pulsars (B1718-19, J1723-2837, B1744-24A, B1957+20, J2051-0827), to search for the effects of plasma lensing, and to make use of the new Parkes Ultra Wide Band Low Frequency (UWL) receiver, which will allow us to resolve lensing events in frequency and time, which is crucial for constraining physical parameters. This study will help determine how ubiquitous the effects of plasma lensing are in eclipsing binaries, put improved physical scales on the locations of pulsar emission, and help shed light on the nature of eclipses and evolutionary pathways of these systems.

title: Influences of full fat soybean diets on ovarian follicular development and concentration of progesterone in the postpartum crossbred diary cows

description: An experiment was studied to investigate influences of full fat soybean (FFS) diets on follicular development and concentration of progesterone in the postpartum crossbred dairy cows. Six multiparous and nine primiparous 87.5% crossbred Friesian cows were assigned randomly to a 3 x 2 factorial arrangement to evaluate 3 groups of diets which began after calving to 8 weeks postpartum. Cows received total mixed ration consisted of a 39:61 corn silage:concentrate ratio with 0, 18 or 24% of DM diet as FFS. All diets which were isonitrogenous and isoenergetic and contained 1.4, 4.5 or 5.9%EE, respectively. Dry matter intake (DMI), milk yield, body condition score (BCS) and body weight (BW) were recorded. Milk samples and rumen fluid were collected to analyze milk composition and volatile fatty acids (VFA). Blood plasma was analyzed for glucose, non esterified fatty acid (NEFA) and progesterone (P4) concentrations. Follicular development was monitored by ultrasonography.Results of the experiment showed that average DMI, BCS, BW, milk composition, ruminal pH and VFA concentration were not significantly different (p&gt;0.05) among dietary groups. Average milk yield during the 2nd month postpartum and all experiment period were significant difference (p&lt;0.05) among dietary groups. Average milk yield of 0, 18%FFS versus 24%FFS groups were 16.8, 17.8 versus 20.9 and 16.3, 17.1 versus 19.4 kg/d, respectively. Average EB was more negative (P&lt;0.05) in multiparous cows fed 18%FFS diet than multiparous cows fed 0%FFS diet. The concentration of plasma glucose, NEFA and follicular development did not differ (p&gt;0.05) among dietary groups. However the concentration of plasma P4 in 0 and 18%FFS groups were greater (p&lt;0.01) than 24%FFS group. Augmentation fat supply in form of oilseed from FFS did not influence on follicular development in crossbred Friesian cows but supplementation FFS at 24% of diet apparently led to increase milk yield while it enhanced negative EB (NEB). This greater NEB led to reduce plasma P4 significantly when compared to cows fed 0 and 18% FFS diets.

title: Gauss' Lemma for function fields

description: Let L be a number field and OL the ring of algebraic integers in L. For apolynomial f with coefficients in OL, the content of f in L is the ideal of OLgenerated by coefficients of f. The polynomial f is primitive in L if the contentof f in L is OL. In 2005, Arturo Magidin and David McKinnon proved the Gauss’ lemma fornumber fields, the product of two primitive polynomials is also primitive, andsome applications following from Gauss’ lemma for number fields. A function field K over a finite field k is a finite separable field extension overk(x) where x is a transcendantal element. In this research, we study Magidin and McKinnon’s work on the function fields.

title: Morbidity Expansion among Thai population

description: Average life expectancies of both genders in Thailand tend to increase due to declining birth and mortality rates. Additionally, average life expectancies in the elderly tend to increase considerably. A long life may be a life combining with good health, morbidity, and disability. The purposes of this study were to examine four kinds of trends 1) trends of chronic diseases (hypertension, diabetes) and health parameters (fasting plasma glucose, total cholesterol, and body mass Index) by aged-specific prevalence rates, 2) trends of the activities of daily living disabilities by aged specific rates, 3) trends in age-specific mortality rates of chronic diseases (ischemic heart disease, cerebrovascular disease, and cancers), and 4) trends of the proportion of active life expectancy to life expectancy at age 60 and over. This was a cross-sectional study using secondary data which included morbidity, disability, and mortality data. The morbidity data were derived from the National Health Examination Survey consisting of questionnaire and health exam. The mortality data were extracted from the national vital statistics reports. The disability data were derived from Survey of Elderly in Thailand and estimated active life expectancies were calculated using the Sullivan Method. Results show 1) increasing trends of chronic diseases and health parameters by aged-specific prevalence rates, 2) increasing trends of the activities of daily living disabilities by aged specific rates, 3) increasing trends in age-specific mortality rates of chronic diseases, and 4) declining trends of the proportion of active life expectancy to life expectancy at age 60 and over. In conclusion, Thai population may not only live longer, but also live with morbidity and disability. This study confirms the expansion of morbidity among Thai population. Important policy recommendations are to promote healthy life style such as exercising and eating food full with nutrition, to prepare the nation for aging population including government services for disabled elderly, and to prepare family and community in caring for elderly and elderly with disability.

title: The Consolidation of Stock Exchanges in Small Nations : does it mprove liquidity and development?

description: The purpose of this thesis is to examine the claims of economists and stock exchange management that consolidation of stock exchanges, either regionally or globally, does benefit their consumers. A review of the major issues is addressed prior to testing with two models. The first model examines the claim that consolidating stock exchanges increases liquidity. The second model examines the claim that consolidation increases the size and economic importance of a stock exchange in the nation’s economy. The results indicate that these claims cannot be fully supported as consolidation did not provide significant evidence of improvement in either model. While there may be delayed benefits, or other benefits related to consolidation, there clearly was not an immediate boost in liquidity or market capitalization in multinational exchange groups relative to their collective national peers.

title: The internationalization of the Thai movie industry : an analysis of the export competitiveness to the Japanese market

description: This study was conducted to examine the pattern of internationalization of the Thai movie industry in the case of exports to Japan. Firstly, we adopted the theory of competitive advantage to indentify the factors related to the competitiveness of the Thai movie industry for exports. With the SWOT analysis, the scores in the matrix data of exported Thai movies and its production companies revealed that the empirical data is matched with the theory of competitive advantage and the competitiveness of the Thai movie industry on the supply side have contributed to accelerate the export of Thai movies to Japan. Secondly, we investigated the possible explanations for the pattern of internationalization by other approaches, namely, the Product Life Cycle and the Linder Hypothesis. The analyses revealed that the sudden increase of exported Thai movies abroad during the investigated period coincided with the upward trend or the innovative creation in the product life cycle, as well as the product cycle of the first new interest to movies from a foreign country in the international movie market. The series of successful Thai movies in domestic market in the observed period was also possible due to the structural change of demand in Thailand caused by the economic crisis in 1997. Although the quality increase of the Thai movies was due to both supply side’s competitiveness and demand side’s structural change, however, some of Thai movies could not be exported to Japan due to the cultural discount. Finally, recommendations for public policy include: strengthening the role of scriptwriters which is the weakest factor on the supply side, then reducing the barriers for diversification of the movie contents caused by the censorship, and establishing the so-called Thailand Cultural Foundation to help reducing the cultural discount of the foreign audience in order to form a better understanding of the Thai culture abroad.
