Fragmentation of jets containing a prompt J/psi meson in PbPb and pp collisions at sqrt(s_NN) = 5.02 TeV
No full textJets containing a prompt J/psi meson are studied in lead-lead collisions at a nucleon-nucleon center-of mass energy of 5.02 TeV, using the CMS detector at the LHC. Jets are selected to be in the transverse momentum range of 30 <= pT <= 40 GeV. The J/psi yield in these jets is evaluated as a function of the jet fragmentation variable z, the ratio of the J/psi T-p to the jet p(T). The nuclear modification factor, R-AA, is then derived by comparing the yield in lead-lead collisions to the corresponding expectation based on proton-proton data, at the same nucleon-nucleon center-of-mass energy. The suppression of the J/psi yield shows a dependence on z, indicating that the interaction of the J/psi with the quark-gluon plasma formed in heavy ion collisions depends on the fragmentation that gives rise to the J/psi meson.

Improvement in breakdown characteristics with multiguard structures in microstrip silicon detectors for CMS
No full textTo obtain full charge collection the CMS silicon detectors should be able to operate at high bias voltage. We observed that multiguard structures enhance the breakdown performance of the devices on several tens of baby detectors designed for CMS. The beneficial effects of the multiguard structures still remains after the strong neutron irradiation performed to simulate the operation at the LHC. (3 refs)
Insights into enhancing Centella asiatica organ cell biofactories via hairy root protein profiling
No full textRecent advancements in plant biotechnology have highlighted the potential of hairy roots as a biotechnological platform, primarily due to their rapid growth and ability to produce specialized metabolites. This study aimed to delve deeper into hairy root development in C. asiatica and explore the optimization of genetic transformation for enhanced bioactive compound production. Previously established hairy root lines of C. asiatica were categorized based on their centelloside production capacity into HIGH, MID, or LOW groups. These lines were then subjected to a meticulous label-free proteomic analysis to identify and quantify proteins. Subsequent multivariate and protein network analyses were conducted to discern proteome differences and commonalities. Additionally, the quantification of rol gene copy numbers was undertaken using qPCR, followed by gene expression measurements. From the proteomic analysis, 213 proteins were identified. Distinct proteome differences, especially between the LOW line and other lines, were observed. Key proteins related to essential processes like photosynthesis and specialized metabolism were identified. Notably, potential biomarkers, such as the Tr-type G domain-containing protein and alcohol dehydrogenase, were found in the HIGH group. The presence of ornithine cyclodeaminase in the hairy roots emerged as a significant biomarker linked with centelloside production capacity lines, indicating successful Rhizobium-mediated genetic transformation. However, qPCR results showed an inconsistency with rol gene expression levels, with the HIGH line displaying notably higher expression, particularly of the rolD gene. The study unveiled the importance of ornithine cyclodeaminase as a traceable biomarker for centelloside production capacity. The strong correlation between this biomarker and the rolD gene emphasizes its potential role in optimizing genetic transformation processes in C. asiatica.The author(s) declare financial support was received for the research, authorship, and/or publication of this article.

ABSTRACT
HYGIENE EDUCATION PROGRAM IN LUMBAR SPINE FOR FLEET HELPERS OF A SOFT DRINKS DISTRIBUTOR FROM BARQUISIMETO CITY
In order to design a lumbar spine hygiene education program for assistants fleet of a soft drinks distributor in Barquisimeto, an investigation was made feasible project type, which had a target population of 91 workers who were questionnaire to measure their knowledge level about hygiene column. The instrument consists of twenty questions with single response and it was validated by expert's judgment through a numerical scale created by the author of the research. For data processing it was used SPSS 18 statistical program and percentage measure was used, while for the presentation of the results were used frequency distribution tables and simple bar graphs. It was registered that the knowledge level on lumbar spine hygiene was correct in 45.65% of the workers and the areas of greatest need education are training back school and the importance of healthy posture. Technical administrative feasibility was validated for the educational program development, whereby it was proceeded to be designed and proposed for the purpose of producing behavioral changes in the working population regarding healthy posture and thus decrease the morbidity associated with lumbar spine pathology and improve their quality of life.

Current distribution of arthropod of public health relevance in Italy: results from systematic reviews.
No full textINTRODUCTION
Within the INF-ACT project task 2.3.1. PE13 – RESEARCH NODE2 (Gathering of data on vector
presence/abundance/resistance to insecticide in Italy from scientific and grey literature) three
different working groups (one for each arthropod group) were selected for mosquitoes (M), sand flies
(S) and ticks (T). The aim of the work is to systematically review the existing published literature of the last 22 years related to the occurrence (geographic presence and distribution) of mosquito, sand fly and tick species in Italy.
MATERIALS AND METHODS
For the screening of publications, we considered all studies published in peer-reviewed journals
obtained from the literature search on major databases (Scopus, CABA, EMBASE, WoS, MEDLINE).
The selection for relevance and eligibility of these studies (title and abstract) has been carried out by
working groups that included volunteers (M: 28, S: 18, T: 24), gathered in pairs and working independently, solving the potential disagreements on study eligibility, if necessary, with the examination of the studies by a third reviewer. Only publications with Italian or English full text were
considered for the first screening of relevance, therefore publications without available full text in
these two languages were excluded. In order to avoid double counting of the studies published more than once, the papers were compared juxtaposing author names, geographic area of the studies, the sample sizes and the outcomes.
RESULTS & CONCLUSIONS
The results of the first phase are shown below sorted by systematic group. The volunteers received in total 6,909 (M), 1,981 (S), 12,018 (T) selected records, and extracted by all five used databases. 751 (M), 440 (S), 1,494 (T) of them resulted accepted, 515 (M), 597 (S) doubtful and 5,643 (M), 944 (S), 10,524 (T) rejected. It should be noted that for ticks group no doubtful papers are present because of the already screened abstracts. In conclusion, hitherto 12.8% of the papers screened from the literature were found to be suitable for the eligibility criteria and will be subjected to full-text screening). Aim of the next working step will be the creation of a unique database shared among involved groups (mosquitoes, sand flies and ticks) and, after full-text retrieval, reviewers will extract data from text, tables, or figures and will gather them into pre-defined tabular forms. As previously explained extracted data, will pass a double crosschecking procedure, operated by two reviewers independently. An additional comparison of all extracted data will be scheduled with the original selected studies.
Full-text examination is still ongoing and as soon as data collection phase will be completed thematic
systematic review manuscript will be produced

Evaluating the Effectiveness of Offsets as a Mechanism for Promoting Malaysian Defence Industrial and Technological Development
No full textCranfield UniversityOffsets have taken centre stage in defence trade. To date, more than 78 countries around
the world practice offsets and outstanding offsets obligations run into billions of US
dollars However, why have offsets gained such a momentum? Increasingly, both sellers
and buyers in the arms trade view offsets as an efficient and effective economic
compensation tool to justify arms deals. Buyers, consider offsets as a catalyst for
industrial and technological development, employment, creation of value-added
activities and skills development. Sellers, on the other hand, perceive offsets as
providing product differentiation and competitive advantage in an already tough defence
market. The question, though is whether, do offsets really work as claimed? The
purpose of this dissertation is to empirically verify the above proposition by evaluating
the effectiveness of defence offsets in developing a defence industrial and technological
base, using Malaysia’s defence industry as a case study.
This study employs a Multi-Method or Triangulation Methodological approach
(comprising survey, archival sources and participatory observation) to gather data.
Fieldwork research employing questionnaires and interviews were undertaken as part of
a survey of Malaysian defence companies, international defence contractors and
relevant offsets-related government and non-governmental agencies. These data were
further substantiated and consolidated via archival sources, such as government and
company reports and also participatory observation.
Research analysis indicates that offsets have provided mixed results, in the case of
Malaysia. The successes have been mainly focused on technology capability-building
and human resource development, limited to through-life-support of the defence
equipment and the ancillary systems purchased. Morover, offsets have been
successfully used to diversify into civil sectors, mainly aerospace and electronics
sectors, leading to increased exports, jobs, backward linkages and technology
enhancement in these sectors. However, offsets have had minimal effect on creating
joint-production, collaborative activities and R&D programmes, requisites for the
process of Malaysianisation. Further, offsets have also been less than effective in increasing employment, and dual-use technology programmes that could provide longterm
impact on Malaysia’s economic growth.
Overall, Malaysia’s offsets policy has been pragmatic and flexible. The government has
played a vital role in ensuring that the offsets policy operates in tandem with Malaysia’s
national aspirations. Yet, offsets have had a limited impact on developing and
sustaining Malaysia’s defence industrial and technology base. The offsets policy aim
and objectives have not been clearly reflected in the offsets process and implementation.
As defence offsets will continue to be of an essence in Malaysia’s defence procurement
activity, initiatives should be taken to review the offsets policy and implementation
processes. The review should augment the effectiveness of offsets in developing
measurable and value-added programmes that build a sustainable and competitive
Malaysian defence industry. To this end, and based on the research findings of this
study, a number of important policy recommendations are advanced to raise the
effectiveness of Malaysia’s offsets policy
