Tomato composition and nutritional value are attracting increasing attention and interest from both consumers and producers. The interest in enhancing fruits’ quality with respect to beneficious nutrients and flavor/aroma components is based not only in their economic added value but also in their implications involving organoleptic and healthy properties and has generated considerable research interest among nutraceutical and horticultural industries. The present article reviews up to March 2020 some of the most relevant studies based on the application of NMR coupled to multivariate statistical analysis that have addressed the investigation on tomato (Solanum lycopersicum). Specifically, the NMR untargeted technique in the agri-food sector can generate comprehensive data on metabolic networks and is paving the way towards the understanding of variables affecting tomato crops and composition such as origin, variety, salt-water irrigation, cultivation techniques, stage of development, among many others. Such knowledge is helpful to improve fruit quality through cultural practices that divert the metabolism towards the desired pathways and, probably more importantly, drives further efforts towards the differentiation of those crops developed under controlled and desired agronomical conditions.

Heriyanto et al, 2018. Analysis of the Production Factors of the People's Palm Oil According to the Land Typology in Indragiri Hilir Regency, Riau Province. JLSO 7(1): Palm oil commodities are one of the plantation sub-sector commodities that increase the income of farmers and the community, provide processing industry raw materials that create added value. The land cultivated by independent oil palm farmers consists of land land, tidal peatlands, coastal peatlands and coastal land. The difference in typology of this land will contribute to different production. The research aimed to analyze the oil palm production and the dominant factor affecting oil palm production according to the typology of land in Indragiri Hilir Riau Province. The data were analyzed using descriptive statistics and built multiple regression models with the dummy variable method of Ordinary Least Square (OLS). The results of the study showed that the production of oil palm cultivation on land is the highest compared to the typology of tidal peatland, coastal peat and coastal land. The dominant factors affecting palm oil production in Indragiri Hilir Regency were the amount of fertilizer use, labor, age of plants, herbicides and dummy typology of land. In order to obtain optimal production, this study recommended doing oil palm farming in accordance with the correct cultivation techniques in accordance with the characteristics of land typology. Besides that the use of balanced fertilizer (elements of N, P, and K) in accordance with the recommended needed to be applied.

Purpose The purpose of this paper is to present the methodological issues around developing a quantitative research instrument of the social impact of Polish public libraries. The results of the use of this instrument to survey users of Mazovian Province, Poland, are summarized as an example of its use. Design/methodology/approach The research focused on informational, educational and participatory aspects of social impact on the sidelines leaving cultural heritage issues. “Impact” and “social impact” were defined according to ISO 16439:2014. Information and documentation – methods and procedures for assessing the impact of libraries. The research instrument included questions both about the activities taken in libraries by its users and the benefits they gained. The questionnaire also contained questions which allowed to control the variables such as frequency of using libraries, socioeconomic factors and cultural practices. To describe dependencies, various statistical tests were applied. The study was conducted on the group of 1,098 users of 38 public libraries between February and June 2017. Findings Younger and people from smaller towns felt more benefits from using libraries. There are significant differences between types of benefits people of various age, financial status and household size experienced. People who went to libraries and other cultural institutions often experienced more benefits. The more a person performs activities in libraries, the more benefits he or she has. Some added value of particular activities is also visible. Research limitations/implications Despite the efforts and the size of the sample, it is not representative of the population of library users in the Mazovian Province (mainly due to the data collection method – auditory survey). Originality/value Studying the social impact of the libraries in Poland is still at its beginning. The presented research is, therefore, exploratory in terms of cognitive and methodological value.

Pre Treatment

Agricultural crop production around the world is adversely affected by excess salt accumulation in the soil. Plants initiate broad range of signal transduction pathways to respond any stress. Salicylic acid (SA) is an endogenous plant growth regulator that acts as a signal molecule to modulate plant response by reducing the effects of abiotic stress on plants. The main objective of this study is to examine whether exogenous salicylic acid pre-treatment may reduce the adverse effects of salt stress and enhance salt tolerance in Solanum lycopersicum. For this experiment, two weeks old seedlings were subjected to salt stress by adding salt water (100 mM NaCl) for three days with or without salicylic acid pre-treatment. After salt stress exposure plant leaves were harvested and the various measures were recorded. Results of this study exhibited that salicylic acid pre-treatment mitigates various advers effects of salt stress on plant growth by stimulating plant biomass, water relations, protein content, chlorophyll pigment, and inorganic osmolytes accumulation. Simultaneously, an increase in activity of antioxidant enzymes of SOD, CAT and POX were also triggered.  This current study suggested that pre-treating of Solanum lycopersicum with salicylic acid attenuates the depressive effect of salinity by accelerating the osmolyte accumulation and triggering activity of free radical scavenging enzymes.

Gresik is well known as one of the Islamic based tourism towns in East Java. This Islamic tourism encourages the development of typical souvenirs business in Gresik especially in food sector. Some Gresik traditional food are often used as souvenirs, such as pudak, jubung, and ayas. High sale promotes product innovation, especially in terms of taste creations, preservation / shelf life, as well as packaging. Unfortunately, these product innovation have not been supported with information related to product nutritional value. The nutritional value is important, considering the usage of information in food labelling as well as for the materials, process and packaging basic innovation. The study of Gresik traditional food nutritional value products consists of two stages, they were field-related observation and laboratory testing. Field observations were done to obtain information on raw materials and production processes from pudak, jubung and ayas. As for the test of nutritional value was done by proximate test. The results showed that pudak has moisture content (55.6%) twice higher than jubung and ayas (25.0% and 22.7%, respectively). All three products have a low fat content, which was below 1.0 g per serving. The protein content is also relatively low, i.e. only 2.1-2.8%. All three of these products are carbohydrate sources with the amount of 40.8-73.4% which gives a caloric amount of 120-185 kcal per serving. Implementation of nutritional information in food label could also give added value to the product.

Variationist Sociolinguistics

Researchers in language variation seek to understand how linguistic, social, and individual factors influence speakers’ choices within sets of related variable forms as in, for example, the alternation between working and workin’ in English. A central premise in this approach is that the variation observed at all linguistic levels is not random. Rather, provided that one has sufficient information about speakers’ backgrounds and the linguistic contexts in which a variable form occurs (e.g., whether a final /t/ or /d/ in English followed by a consonant or a vowel), one can predict, in a probabilistic sense, which speakers will be more likely to choose one variant or another. Further, variationists maintain that variation is an essential characteristic of language change. By applying rigorous multivariate statistical analysis to a wide range of variable forms at all linguistic levels, ranging from phonetic detail to language choice, variationists have demonstrated conclusively that most of the variation that is observed in language is highly systematic. The demonstration of systematic variability has been particularly important for minority languages and dialects, which, until the development of sociolinguistics, were often regarded as imperfect copies of the standard languages or dialects with which they co-existed. In recent decades, variationists have expanded the scope of their work and shown that systematic variation is characteristic of all human languages regardless of modality or stage of development. Research on variation in sign languages, for example, has shown that they are subject to many of the same linguistic and social influences as spoken languages. Moreover, language learners, whether first, second, or nth, have been shown to vary systematically in their use of forms that are usually considered obligatory in the target language as well as in their use of forms that vary in the target language. Finally, variationists have sought to use the findings from their research to improve conditions in the communities from which they draw their data, particularly in education for children who speak a minority language or dialect.

Fruit wastes and side-streams can be used for vinegar production to create added value for the agri-food sector and enhance farmer incomes and local economies. In this study, methods for vinegar production by wild and selected acetic acid bacteria (the quick starter Acetobacter aceti and the acid-resistant Komagataeibacter europaeus), free (FC) and immobilized (IC) on a natural cellulosic carrier, are proposed using sweet wine made from the industrial finishing side-stream (FSS) of Corinthian currants as raw material. The results showed all cultures can produce vinegar with 46.65 ± 5.43 g/L acidity, from sweet FSS wine containing 5.08 ± 1.19% alcohol. The effect of immobilization was more obvious in the case of the selected culture, presenting better acetification efficiency, both fresh and after cold storage for 2 months. The vinegars had an antioxidant capacity of 263.5 ± 8.4 and 277.1 ± 6.7 mg/L (as ascorbic acid) and phenolic content 333.1 ± 12.0 and 222.2 ± 2.9 mg/L (as gallic acid) (for FC and IC, respectively). They also had a rich volatilome (140 compounds identified by SPME GC-MS), with higher percentages of esters identified in vinegars made by IC. The results are encouraging for vinegar production with IC of a mixed A. aceti and K. europaeus culture.

The focus of this paper is a case study on the municipality of San Javier in Spain. The aim of the analysis was to provide a working model for the integration of the assessment and conservation of built heritage into broader projects devoted to the sustainable restoration of natural spaces undergoing evident declines in habitability. With a population of 31,905, San Javier is located on the edge of the Mar Menor, which is one of the largest permanent salt water lagoons in the Mediterranean. It forms part of the coastal region of the Autonomous Community of the Region of Murcia in the southeast of the Iberian Peninsula. San Javier is one of four municipalities that administer this unique ecosystem. However, despite being designated as a protected natural site since its 14 beaches are one of the most important national and international tourist destinations in this Autonomous Community, since 2016, it has suffered one of the worst environmental crises in its history. One of the outcomes of this situation is that the government bodies involved have begun to seek new models for the area’s complete regeneration that would enable sustainable growth and also include the social and economic sectors that have, to date, played a secondary role in managing the area. In this regard, cultural heritage should play a key role. The aim of this study was to demonstrate that the region’s cultural heritage, despite the complex issues involved in its management, especially for the local administrative bodies, can contribute to the creation of new models for regeneration. Besides the added value of cultural prestige provided by this area’s unique cultural landscape, which is a further legacy of the region’s history and artistic development, engaging with cultural heritage facilitates the revival of traditional systems that contribute to environmental improvement. Finally, this paper provides tools that enable local groups, and, above all, the residents themselves, to identify with the values of their cultural heritage.
