Comparative Study of CV3 Carbonaceous Chondrites Allende and Bali Using Micro-Raman Spectroscopy and SEM/EDS

The birth of the solar system (over 4 billion years) is speculated to have happened from a nebula, swirling and compacting in localized regions to eventually form the Sun and planets. This complex process consists of numerous changes and intermediary steps, yet to be fully understood. Carbonaceous chondritic meteorites are relics of that process and therefore have potential to reveal information about the formation history. Several theories have been formulated linking their composition to planet formation. This study focusses on two carbonaceous chondritic specimens, Allende and Bali, both of the group CV and petrologic type 3. CV meteorites are abundant in inclusions (e.g. chondrules), which are considered the oldest objects to have formed in the solar system. Samples were studied using micro-Raman spectroscopy, scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM/EDS). Chondrules were identified in the Allende sample, while Bali had several irregular inclusions and small crystals. These other inclusions were refractory inclusions rich in Ca and Al. Elements common to both were: O, Si, Fe, Mg, C and S. Ni, Ca and Al were also present but varied in relative percentage weight in each sample. Bali had several Fe-Ni spots, while no such spots were identified in Allende. S-rims were seen around inclusions in both, as was the Fe/Mg complementarity between matrix and inclusion. Minerals found in both were graphitic carbon and Mg-rich olivine. Allende also contained pyroxene and quartz; while Bali had larnite, magnetite and awaruite. Information obtained about the parent bodies of these samples includes their peak metamorphic temperatures and extent of secondary alterations (post-accretion). Allende was found to be more metamorphosed than Bali. Possible implications from the obtained results have been discussed in the light of planet formation models, such as that the formation of the inclusions and surrounding matrix could have taken place in the same local nebular region. Overall, the findings from this study agree well with literature and add to the studies conducted within the planet formation community. Table of
New Conditional Symmetries and Exact Solutions of the Diffusive Two-Component Lotka–Volterra System

The diffusive Lotka–Volterra system arising in an enormous number of mathematical models in biology, physics, ecology, chemistry and society is under study. New Q-conditional (nonclassical) symmetries are derived and applied to search for exact solutions in an explicit form. A family of exact solutions is examined in detail in order to provide an application for describing the competition of two species in population dynamics. The results obtained are compared with those published earlier as well.
The Perceptions about Their Profession of Kosovo`s Nursing Students

Background and Aim: Nurses are key to the health of the nation. Nursing can be described as both an art and a science; a heart and a mind. The aim of this study is to evidence the students' perceptions about the profession of nursing. This is a cross-sectional study. Study Design: The research question is: "What are the nursing students’ perceptions about the profession of nursing? " Methodology: The study was realized during the period of January- February 2021. The study was conducted with nursing students in first, second and third year of study, in bachelor degree of University of Pristina "AAB College" Kosovo, Faculty of Nursing, Department of Nursing, Kosovo. In this study were included n=130 students, respectively (n= 29, 22.3% in first year, n=57, 43.8% second year and n= 44, 33.8% in third year of study). The questionnaire “Cockrell-Punter Nursing Perceptions Scale” used consisted of 25 perception statements related to nursing. These scores no longer reflected simply agreement/disagreement, but as positive or negative perceptions of nursing with a scale values ranged from 1=negative perception to 5=positive perception. The survey performed in classroom was anonymous. All data collected were elaborated with SPSS version 19. Results: In this study, 22.3% (n=29) of students were male and 77.7% (n=101) were female. Age ranged from 18 to 47 years old. The average age is 21.9 years old. The distribution of student’s age was: (8.5% were 18 years old, 18.5%, 19 years old, 27.7% 20 years old, 19.2% were 21 years old and 26.1% were over 21 years old) mean 19.8 years old, min 18 years old, maximum 47 year old, Std. Dev ± 4.19. According to the residence, 88 (67.7%) of students were from urban area and 42 (32.3%) from rural area. Conclusion: Nursing students have good perception about the nursing profession. With age the level of perception increases, so the oldest have more positive perception.
Risk Management Committee, Auditor Choice and Audit Fees

We find that risk management committees and BIG4 audit firms contribute to audit fees. We use observations of 895 companies registered in Indonesia for 2014–2018, and to answer our hypothesis we used ordinary least squares analysis. The results show that BIG4 weakens the relationship between RMC and audit fees. Our study proves that higher demand for audit coverage will occur if there is a risk management committee within the company. As a result, audit fees increase. RMC may demand high-quality external guarantees, but the presence of BIG4 as a moderating variable reduces the relationship between the two variables. We assume that this can happen because auditors can work more efficiently if the company has an RMC, auditor(s) could indirectly reduce the risk because it is partially results from the performance of the RMC. In addition, we also use the robustness test to handle the endogeneity problem with consistent results as OLS. These findings provide evidence for policy makers about the relationship between audit fees and risk management committees.
Preincubation and preheating – two different methods but with one purpose for use in hatchery. Can their interaction be twice as effective?

SUMMARY The increasing demand for simultaneous hatching of a large number of chicks has led to the need for refrigerated egg storage often over 7 days. This results in low embryo viability, low hatchability, and poor quality of chicks. To overcome these negative effects, chick producers follow a preincubation step, i.e. temporary warming of eggs to temperatures above physiological zero. Depending on the length of the planned storage, the age of the reproductive flock and the poultry species, three different preincubation profiles can be used: single (PI), multiple with an equal number of hours for each PI (SPIDES), and increasing duration of elevated temperature with each successive PI (EG SPIDES). However, this technology does not overcome the negative effects of heating eggs too quickly or too slowly to the required incubation temperature. Currently, this issue increasingly affects commercial hatcheries, which face the challenge of simultaneously raising the temperature of a very large number of eggs. In this case, preheating by a gradual temperature increase can help. Similar to preincubation, the preheating profile should be adjusted to the duration of egg storage and age and genotype of the reproductive flocks. As both methods have the same goal but different mechanisms of action and are used at different stages of egg storage, the analysis of their interaction will be crucial to further improve hatching efficiency in the future.
Who Votes: City Election Timing and Voter Composition

Low and uneven turnout is a serious problem for local democracy. Fortunately, one simple reform—shifting the timing of local elections so they are held on the same day as national contests—can substantially increase participation. Considerable research shows that on-cycle November elections generally double local voter turnout compared with stand-alone local contests. But does higher turnout mean a more representative electorate? On that critical question, the evidence is slim and mixed. We combine information on election timing with detailed microtargeting data that includes voter demographic information to examine how election timing influences voter composition in city elections. We find that moving to on-cycle elections in California leads to an electorate that is considerably more representative in terms of race, age, and partisanship—especially when these local elections coincide with a presidential election. Our results suggest that on-cycle elections can improve local democracy.
Mediterranean Subspecies versus Californian Varieties: An Example from Acmispon (Leguminosae, Loteae)

The tribe Loteae of the family Leguminosae has major centers of diversity in the Mediterranean Region and California. It is used here to illustrate different traditions of taxonomic interpretation of infraspecific variation among researchers in different continents. Recent accounts of European and Mediterranean taxa commonly make an emphasis on recognizing subspecies. In contrast, accounts of North American Loteae recognize all infraspecific taxa as varieties. Harmonization of taxonomic concepts across continents is essential for a more accurate representation of data in global biodiversity databases. It is reasonable to use the rank of subspecies for geographically defined infraspecific units with localized zones of intergradation. Such subspecies may be at least partially compatible across continents and taxonomic groups. In the present paper, we discuss taxa traditionally included in or associated with Acmispon glaber (Vogel) Brouillet (=Syrmatium glabrum Vogel) and demonstrate a need for recognizing three species, of which one has three geographically defined subspecies. Required nomenclatural combinations are proposed. It is proposed that subspecies rather than varieties should be recognized in a number of other species of North American Loteae (and other plant groups). Inland subspecies of Acmispon glaber and A. maritimus offer an opportunity for comparative analysis in an eco-evo-devo framework.
Substitution of Sweet Potato (Ipomoea Batatas) and Soybean (Glycine Max.) Flour with Durum Wheat (Triticum Durum) Flour Effect on Physicochemical and Sensory Characteristics of Cookies

Cookie production is currently limited to wheat and few cereal grains in many countries. This study was initiated with the objectives of investigating the possibility of producing cookies from blends of durum wheat, sweet potato and fermented soybean flours at the ratio of 100:0:0, 75:25:0, 75:0:25, 75:22.5:2.5, 75:2.5:22.5, 75:20:5, 75:5:20, 75:17.5:7.5, 75:7.5:17.5, respectively. The cookies were evaluated for physical properties such as diameter, thickness, and spread ratio; proximate compositions (moisture content, total ash, crude fat and crude protein); and sensory attributes like color, taste, crispness, texture, appearance and overall acceptability. Physical characteristics; the ratio of sweet potato and soybean flour increased in cookies preparation with wheat flour increased the diameter, thickness and spreading factor of cookies to some extent. There were valuable effect on proximate composition of the product (sweet potato and soybean ratio increase in cookies formulation made irregular increase and decrease, respectively in the product moisture content. The fat content of cookies was decreased and irregularly increased with increased ratio of both sweet potato and soybean, respectively. Both sweet potato and soybean ratio increment in the product, resulted in the irregular increase of total ash. Protein content of cookies was decreased for the increased ratio of sweet potato and increased for the increased ration of soybean. Sensory acceptability evaluation of the product based on color, taste, crispness, texture, appearance and overall acceptability was preferred by the panelists without any difference. Keywords : Cookies, physical properties, proximate composition, sensory characteristics. DOI : 10.7176/FSQM/83-02
Ceratozamia aurantiaca (Zamiaceae): A New Cycad Species from the Northern Rainforests of Oaxaca, Mexico

Ceratozamia aurantiaca, a new cycad species from Oaxaca, Mexico, is described. The new species is endemic to lowland karst tropical rainforests of the northern mountains (Sierra Norte region). This species is related to C. subroseophylla and C. robusta, together considered part of the C. robusta species complex due to their shared characteristics: robust, upright trunk; large and long leaves with densely armed petioles and linear to subfalcate leaflets; and large megastrobili. Ceratozamia aurantiaca, as the epithet suggests, is easily distinguished from other species by the orange color of its emerging leaves, a trait unique in the genus. Additionally, C. aurantiaca is distinguished from C. subroseophylla and C. robusta by having significantly shorter petioles, wider spacing between leaflets, and wider median leaflets. The taxonomic recognition of this species represents a step toward clarifying species delimitation in the C. robusta complex.
Nanocrystal Symmetry Breaking and Accelerated Solid-State Diffusion in the Lead–Cadmium Sulfide Cation Exchange system

The phenomenology of solid-state transformations in nanoparticles is important for applications utilizing their reactivity and for investigations into how nearby interfaces interact with the defects responsible for mass transport. We directly interrogate the structure and reaction kinetics of lead sulfide (PbS) nanocrystals undergoing cation exchange in organic solution to cadmium sulfide (CdS) via X-ray diffraction. The epitaxial relationship of zincblende CdS to rocksalt PbS breaks the overall symmetry of the core–shell nanocrystal without requiring the loss of unit cell symmetry, leading to anomalous peak shifts in the diffraction pattern. Conversion occurs in three stages: (1) surface exchange to form a metastable rocksalt CdS shell, (2) crystallization of this shell to zincblende, and (3) diffusive transport of ions through the completed shell. The interdiffusion coefficient, D, for ions diffusing through the shell follows the Arrhenius relationship with an activation energy of 160–180 kJ mol–1, whi.
Feline obesity: risk factors and clinical and metabolic findings

Excess body fat can cause a series of metabolic and mechanical effects on the body. Therefore, this study aimed to verify the clinical, metabolic, and risk factors of overweight (OW) cats. For the acceptance of participation in the research, the tutors were asked to answer a questionnaire containing 34 questions and to point out the body condition score (BCS) on a sheet containing nine images of different scores (1 to 9 on a 9-point scale). Thereafter, the body evaluations were performed as a classification of the BCS on a scale from 1 to 9, with an ideal score (IS) of BCS 5 and OW for BCS > 5. Further, the lean mass index and morphometric measurements (thoracic and abdominal circumferences and height and length of the patella to calcaneal tuberosity) were performed to estimate the percentage of body fat. Systolic blood pressure was measured using the non-invasive Doppler method and blood was collected for hemogram and serum biochemistry (creatinine, urea, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, glucose, triglycerides, and cholesterol). After these analyses, we sought to guide and raise the awareness of the tutors to promote the correct nutritional and environmental management of the animals. Thirty adult cats were divided into two groups, based on the classification of the BCS, with eight having an IS and 22 being OW. The OW group was found to have a low level of physical activity, hypercholesterolemia, and higher values of body characteristics. Additionally, there was a median agreement between the perceptions of the clinician and the tutors. Therefore, it was concluded that the main laboratory alteration found in the obese cats was hypercholesterolemia, which was a critical parameter. It was observed that a low degree of physical activity could cause excess weight gain. It was found that the guardians of the cats with ideal weight underestimated the BCS, which could contribute to the supply of excess food and consequently, obesity. Thus, this study was sought to guide and raise the awareness of tutors, to promote the correct nutritional and environmental management thereby providing welfare and quality of life to the animals.
In Vitro Screening of Plant Materials to Reduce Ruminal Protozoal Population and Mitigate Ammonia and Methane Emissions

Alternative feed sources can be utilized to reduce enteric methane (CH4) emissions, a major greenhouse gas that contributes to global warming. This study aimed to evaluate the potential use of tropical plants to improve digestibility, reduce protozoal populations, improve rumen fermentation, and minimize methane emissions from ruminants. The plants considered herein grow in tropical climates, are easily accessible in large quantities, and are directly related to human food production. Nine plants that grow naturally in tropical climates were assessed. Plant supplementation substantially enhanced accumulative gas production at 24 h (p < 0.05). The apparent organic matter digestibility (AOMDvt) of the diet was not affected by five of the nine plants. With the addition of the plant material, ammonia nitrogen concentrations were reduced by up to 47% and methane concentrations were reduced by 54%. Five of the nine plant materials reduced methane production in terms of CH4/dry matter and CH4/digestibility of the organic matter by 15–35% and 8–24%, respectively. In conclusion, supplementation with plants with high tannin contents was shown to be a viable strategy for improving rumen fermentation, reducing protozoal populations, and limiting methane emissions. In this regard, the leaves of Piper sarmentosum, Acmella oleracea, Careya arborea, and Anacardium occidentale were especially promising.
Progressive effects of nigella sativa ogaiast the interaction of sodium nitrite and sun - set yellow in albino rats

It has been noticed that kids usually eat and drink food containing food preservator and food colorants at the same time. This behavior has been attracted the attention to study the interaction between one of food preservatives ( sodium nitrite NaNO3) and one of bood colorants (sunset -yellow S.S.Yellow). The interaction of the limited dose of these two components resulted in a lethal dose. So, 1 /10 of this dose was used for 30 days and left for another 15 days post the last dose for recovery. Other group was supplemented with Nigella sativa ( N.S) oil in addition to the same mixture. Ingestion of (NaNO3 and S.S.Yellow) mixture significantly decreased rat's body weight, RBC and WBC counts, Hb%, Hct%, serum inorganic phosphorus, serum protein and serum albumin. Significant increases were observed in serum glucose, T3, T4, calcium, -GT, LDH, CPK, Alk.ph and cholesterol. Also cholesterol of brain, liver and heart were significantly elevated. No changes were recorded for; organ/body weight, respiratory rate, heart beats, rectal temperature, acid phosphatase activity, AST and ALT activities of serum and tissues, protein of tissues, serum globulin, and total lipids of serum and tissues, cholesterol of muscle and kidney and serum triglyarides. A complete recovery of most biochemical and haematological parameters was observed days after stoppage of the mixture or after administration of Nigella sativa oil. This study ringe bells of dangerous. The study showed also that even the permitted colourants and food preservatives when taken together or if taken in excessive quantity may be harmful. Therefore, provision should be made for quantities estimation of food additives in various food stuff.
Developing Engineering Identity in an Introductory Engineering Course: A Multi-Case Analysis

: Research in engineering education has identified several factors relevant to the development of students’ identity as engineers. Here we examine the engineering identity of undergraduate engineering students after an introductory engineering course. The specific research question explored here is: "How do engineering students in an introductory engineering course interpret competence, performance, and recognition in relation to their identities as engineers? ” We used a modified engineering identity framework to explore the development of engineering identity within the undergraduate engineering context through a multiple case study approach. Six students majoring in engineering participated in the study. The students had divergent perspectives on what it meant to be competent as an engineer. In all cases, students connected both competence and performance as an engineer with persistence. At this introductory stage, self-recognition as an engineering person took center stage for each student. All were able to identify themselves strongly as an engineering person. The findings add to the current understandings about the development of engineering identity, and suggest that engineering identity may be critically important in conversations about the steps faculty may take in working with students to promote increased retention of undergraduate students in engineering.
Role of TBP on the extraction of trivalent f-cations with CMPO dissolved in a room temperature ionic liquid

ABSTRACT A detailed study on solvent extraction and optical spectroscopy was performed to understand the extraction of trivalent actinides by the solutions of CMPO (octylphenyl-N,N-diisobutyl-carbamoyl methyl phosphine oxide) in a room temperature ionic liquid (RTIL), viz. 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, [C4mim][NTf2]. Solvent extraction studies of Am(III) from nitric acid solution indicated an ion-exchange extraction mechanism. Slope analyses on the distribution data revealed that the stoichiometry of the extracted complex of Am3+/CMPO changed from 1:3 (Am/CMPO) in the absence of tri-n-butyl phosphate (TBP) to 1:2 in the presence of TBP. The distribution ratio values of Am(III) decreased significantly in the presence of TBP suggesting that the latter has an important role in the complexation of CMPO with the metal ion. The extraction of acid increased many folds in the presence of TBP as compared to the bare CMPO solution. The absorption and emission spectra of the extracted complex in RTIL differ significantly in the presence and absence of TBP, signifying the role of TBP in the CMPO-RTIL solvent.
National culture and corporate carbon performance

This study investigates the effects of cultural, institutional and natural ecosystems on corporate response to climate change. We find that national cultural tendencies towards future orientation, uncertainty avoidance, gender egalitarianism and humane orientation strengthen corporate performance, whereas certain other cultural dimensions, such as in-group collectivism, pose barriers to optimal carbon performance. We suggest that culture provides an incremental explanation for corporate climate behaviours beyond socioeconomic or regulatory determinants. Our study contributes to the carbon literature by comprehensively examining the role of a country’s national culture in determining corporate carbon performance, and its findings may help in the implementation of international climate accords (such as the Paris Agreement of 2015) in countries with heterogeneous cultural values and natural environmental contexts.
