Mineral-filled biopolyester coatings for paperboard packaging materials: barrier, sealability, convertability and biodegradability properties
Authors: Helanto Karoliina , Talja Riku , Rojas Orlando J. 
Published: January 2022

Abstract
Changing trends in packaging materials has been driven by increasing environmental awareness as well as legislation. In this context, paperboard-based packaging have become increasingly popular due to its bio-based origin, potential biodegradability and physical properties. However, conventional systems lack behind in barrier performance and heat sealability. Hence, the addition of functional layers have been considered as alternative solutions to this challenge. Here we propose a biodegradable PLA-based polymer coating filled with minerals (0–10 wt% loading), namely, talc, kaolin and calcium carbonate, all of which were used in surface application on uncoated folding box board. For this purpose, we used a pilot-scale extrusion unit that produced materials that were tested for key properties. We found that the presence of filler in the PLA layer improved both water vapor (up to 16 %) and oxygen (up to 56 %) barrier properties. Moreover, the main effect of the fillers was observed in heat sealability, which was improved via adhesion at low temperatures, resulting in full fiber tear. Cup forming was less effected by filler loading in the PLA coating while repulping tests indicated the presence of large flakes of the polymer coating in 1 %-consistency slurries. Finally, biodegradability was slightly delayed in filler-containing samples (biodegradation within 10–60 days), most likely due to the nucleating effect of the fillers. Nevertheless, all the samples can be classified as biodegradable. Overall, our results represent a step forward in scale-up adoption of PLA-based coatings most useful in the development of packaging materials.

An insight review on formation damage induced by drilling fluids
Authors: Kalhor Mohammadi Mojtaba , Riahi Siavash , Boek Edo S. 
Published: January 2022

Abstract
Formation damage is an essential part of drilling and production evaluation, which has a significant effect on well productivity and economics. Drilling fluids are significant sources of formation damage by different mechanisms. This article reviews the research works published during the past 30 years on formation damage associated with drilling fluids, including mechanical damage, chemical damage, and interaction with reservoir rock and fluids. Different filtration techniques, fines migration, and invasion models are discussed based on past studies and recent advancements. Laboratory experiments, methodology, and various aspects of evaluation are considered for further study. Despite presenting different authors’ views and experiences in this area, there is no integrated approach to evaluate formation damage caused by drilling fluids. Finally, the authors analyze the knowledge gap and conclude that a methodology must be designed to improve drilling fluids to prevent formation damage. Recent advances in the area of nanotechnology show promising alternatives for new methods to prevent formation damage.

Abstract
Solvothermal reaction of Bi(NO3)3·5H2O with the flexible ligand 1,3,5-tris[4-(carboxyphenyl)oxamethyl]-2,4,6-trimethylbenzene (H3TBTC) in methanol at 120 °C for 1 h led to the formation of a novel coordination polymer (CP) with the composition of Bi(TBTC). The structure of the microcrystalline material was determined through three-dimensional electron diffraction (3DED) measurements and phase purity was confirmed by a Pawley refinement, elemental analysis, and thermal analysis. The compound crystallizes in the triclinic space group

with one Bi3+ cation and one TBTC3− trianion in the asymmetric unit. Edge-sharing of BiO7 polyhedra leads to the formation of dinuclear Bi2O12 units, which through coordination to six TBTC3− ions form a layered two-periodic structure. Upon heating the material in air, the unit cell volume contracts by 9%, which is attributed to a shift in the inter-layer arrangement and to the flexibility of the building units of the structure. The compound starts to decompose at ∼300 °C. Topological analysis revealed layers consisting of 3-c and 6-c nodes, consistent with the two-periodic kgd net – the dual of the Kagome net (kgm). However, due to the non-planar nature of the Bi(TBTC) layers, adjacent layers are interlaced by polycatenation.

Abstract
Weakley, J, McCosker, C, Chalkley, D, Johnston, R, Munteanu, G, and Morrison, M. Comparison of sprint timing methods on performance, and displacement and velocity at timing initiation. J Strength Cond Res 37(1): 234–238, 2023—Sprint testing is commonly used to assess speed and acceleration in athletes. However, vastly different outcomes have been reported throughout the literature. These differences are likely due to the sprint timing method rather than differences in athlete ability. Consequently, this study compared different sprint starting methods on sprint time and quantified the velocity and displacement of the athlete at the moment timing is initiated. Starting in a staggered 2-point stance, 12 team sport athletes were required to accelerate 10 meters for 10 repetitions. During each repetition, 5 independent timing methods were triggered. The methods were (a) triggering a Move sensor; (b) starting 50 cm behind the line; (c) triggering a front-foot switch; (d) triggering a rear-foot switch; and (e) starting with the front foot on the line. Timing for each method was initiated at different points during the acceleration phase, and the displacement and velocity of the centroid of the pelvis at the point of timing initiation was assessed under high-speed motion capture. The Move sensor had the smallest displacement and lowest velocity at the point of timing initiation, whereas the front-foot trigger demonstrated the largest displacement and highest velocities. Trivial to very large effect size differences were observed between all methods in displacement and velocity at the point of timing initiation. Furthermore, small to very large differences in time to 5 m were found. These findings emphasize that sprint outcomes should not be compared, unless starting methods are identical. In addition, to detect real change in performance, consistent standardized protocols should be implemented.
Wingless Angels: Homer as an Authoritative Historical and Aesthetic Source in Early Modern Period
Authors: Riklius Tomas 
Published: January 2022

This paper discusses the unusual reference to Homer in Federico Borromeo’s De pictura sacra in which Homer is quoted as an authoritative aesthetic and historical source to justify the depiction of wingless angels by Michelangelo. It is said that the great Greek poet represented the gods without wings as if they could move with their feet joined together. The first part of the article examines this relatively obscure remark and its possible sources. One of the reasons for such a quotation is the general Renaissance attitude towards Classical texts to provide a historical perspective and establish an authoritative argumentation. However, a closer analysis discloses that Borromeo refers to Homer not simply as an aesthetic and historical but as a quasi-theological source of God-inspired wisdom.

Odontogenic keratocysts (OKCs) are epithelial developmental cysts. It occurs Mainly in the second and third decades, with a slight predilection for males Usually, OKCs are solitary lesions. They may occur mostly in the Mandible; most commonly in the posterior body and Ascending ramus. Radiographically, OKCs present as A well defined radiolucent lesions with smooth and corticated margins. They may present as a Multilocular or unilocular radiolucent lesion. In most of the cases, there is an unerupted tooth involved with the Lesion.OKC’s is one of the most aggressive odontogenic Cysts due to its high recurrence rate and its tendency to invade adjacent tissue. Treatment Approaches vary in different studies from marsupialization and enucleation, which may be combined with Adjuvant therapy such as cryotherapy or Carnoy’s solution, BIPP to marginal or radical resection.

Analgesic and anti-inflammatory properties of the n-buthanol fraction of Acacia nilotica pods (BF ANP) is investigated in this study. The fraction was subjected for: Phytochemical screening, which revealed the presence of flavonoids, tannin,saponnin, glycosides while the acute toxicity studies showed a relative LD 50 of 565mg/kg (ip). The fraction showed both central and peripheral analgesic activity. In the acetic acid-induced writhing test used to determine peripheral analgesic activity, the BF ANP at the 160,80,40 mg/kg dose inhibits writhing, comparable to reference drug ketoprofen (10 mg/kg) which are all statistically significant (P≤0.001).In central analgesic activity using hot plat method, BF ANP produced central analgesic activity in a dose-dependent manner by elongation of hot plat time when compared to the standard drugs pentazocine. Both BF ANP and pentazocine inhibit significantly licking activity in the formalin-induced pain in mice. Anti-inflammatory activity in the rat paw edema model, BF ANP produced a significant reduction in carrageenan-induced paw edema (p≤0.05). BF ANP when compare to standard drugs ketoprofen is as potent as standard drugs. This study demonstrated that BF ANP possesses significant anti-inflammatory and both central and peripheral analgesic activity due to presence of flavonoids tannin and saponin in that active portion.

The quality of students’ academic achievement (AA) determines the effectiveness in the College of Education (CoE). In the educational sector, resolving low confidence or attachment issues that affect AA may necessitate addressing self-esteem. The main purpose of the study was to examine self-esteem (SE) as a predictor of students’ AA in the CoE in Ghana. The descriptive cross-sectional survey design within the positivist paradigm was employed. Multi-stage sampling procedures were used in the sample selection process. In all, 325 students were selected from six CoE to participate in the study. The questionnaire was used to collect data from the respondents and was tested using inferential statistics (Structural Equation Model, and Moderation analysis). The findings showed that SE predicted students’ AA. The result discovered that gender does not moderate the relationship between SE and AA of the students.

Adaptation of the regional agronomic diagnosis for grapevine yield analysis
Authors: Merot Anne , Metay Aurélie , Smits Nathalie , Thiollet-Scholtus Marie 
Published: January 2022

Yield issues are crucial for winegrowers. In France, yield is often lower than winegrowers’ objectives, and there is a need to understand the causes and magnitude of yield variability in vineyard systems. The yield formation process for grapevine (Vitis vinifera) takes place over two consecutive years. Grapevine is also characterised by a limited control of phenology, a winter dormancy period and the existence of storage organs. We adapted the regional agronomic diagnosis approach as defined by Doré et al. (1997) to quantify grapevine yield variability in two complementary case studies. The regional agronomic diagnosis proved useful in acquiring knowledge on grapevine functioning, reflecting on the data collection strategy, and leveraging interventions to better control yield by integrating multiple factors, particularly in the context of transitioning viticulture systems. Furthermore, the successful application of a regional agronomic diagnosis to grapevine crops can be considered as a major contribution to increasing the understanding of yield formation. It helps winegrowers manage yield variability when addressing planned or unplanned changing conditions, such as an agroecological transition or climate change.
