Inner nest homeostasis in a changing environment with special emphasis on honey bee brood nursing and pollen supply

To reproduce successfully, a honey bee colony has to rear brood efficiently. This requires a fecund queen and depends on the coordinated activities of workers in brood care, in foraging, and in maintaining inner nest homeostasis. Maintaining homeostasis involves thermal regulation of the brood area and providing a steady supply of nutrients, which requires building food reserves during favorable weather so that the brood can be well fed even during times of low nutritional influx. The workforce of adult bees is appropriately divided among the required tasks, and the wax comb itself is spatially organized in a way that saves energy and supports brood nursing. The ability to achieve this homeostasis results from a set of individual behaviors and communication processes performed in parallel by thousands of bees. In this review, we discuss these proximate individual mechanisms that lead to the precise regulation of the complex system that is a honey bee society.

Galaxy spin as a formation probe: the stellar-to-halo specific angular momentum relation

We derive the stellar-to-halo specific angular momentum relation (SHSAMR) of galaxies at z = 0 by combining (i) the standard Acold dark matter tidal torque theory, (ii) the observed relation between stellar mass and specific angular momentum (the Fall relation), and (iii) various determinations of the stellar-to-halo mass relation (SHMR). We find that the ratio f(j) = j(*)/j(h) of the specific angular momentum of stars to that of the dark matter (i) varies with mass as a double power law, (ii) always has a peak in the mass range explored and iii) is three to five times larger for spirals than for ellipticals. The results have some dependence on the adopted SHMR and we provide fitting formulae in each case. For any choice of the SHMR, the peak of f(j) occurs at the same mass where the stellar-to-halo mass ratio f(*) = M-*/M-h has a maximum. This is mostly driven by the straightness and tightness of the Fall relation, which requires f(j) and f(*) to be correlated with each other roughly as f(j) proportional to f(*)(2/3), as expected if the outer and more angular momentum rich parts of a halo failed to accrete on to the central galaxy and form stars (biased collapse). We also confirm that the difference in the angular momentum of spirals and ellipticals at a given mass is too large to be ascribed only to different spins of the parent dark-matter haloes (spin bias).
Topoisomerase I and II Expression in Recurrent Colorectal Cancer Cells: A Dubious Matter

DNA topoisomerases are enzymes which alter and modify the topology of double-stranded DNA, without changing the sequence of the structural units of DNA, namely the nucleotides. They act by transiently breaking and then religating the DNA helix. Therefore, they unwind the double helix, relaxing the supercoiled DNA, and they allow DNA strands or double helices to pass through each other. Topoisomerases are essential for replication, transcription, translation and recombination of DNA because, relaxing the double helix, they facilitate the function of other enzymes, like DNA and RNA polymerases. Topoisomerases are the magicians of the DNA world, as they practically solve all the topological problems occurring during every aspect of DNA metabolism (Gupta et al., 1995; Pommier et al., 1998; Stewart et al, 1998; Champoux et al., 2001; Burden et al., 1998; Kellner et al., 2003; Wang et al., 2002). The first topoisomerase discovered, in 1971, was E. coli topoisomerase I, originally known as ω protein (Wang, 1971). Next year there was the discovery of eukaryotic topoisomerase I in nuclei extract from secondary mouse-embryo cells (Champoux et al., 1972) In 1976, DNA gyrase (topoisomerse II) was purified from Escherichia coli cells (Gellert et al., 1976a). Topoisomerases have been categorized in two basic families, according to their structure and mechanism of action: type I topoisomerases and type II topoisomerases. Type I topoisomerases mediate transient breaks in one of the DNA strands. They are further classified in the subfamilies IA and IB. Type IA topoisomerases form a covalent intermediate with the 5’-phosphoryl end of DNA, while type IB topoisomerases form a covalent intermediate with the 3’-phosphoryl end of DNA (Champoux et al., 2001). On the other hand, type II topoisomersases transiently cleave both of the two DNA strands. They are also further classified in the subfamilies IIA and IIB on the basis of differences in their protein structure. In human and higher eukaryotic organisms, three groups of topoisomerases have been described. The first group includes topoisomerase I and mitochondrial DNA topoisomerase, which are type IB enzymes. The second group includes topoisomerases II┙ and II┚, which are type II enzymes. The third group, which was later discovered, includes topoisomerases III┙ and III┚, which are type ΙΑ enzymes (Lodge et al., 2000; Kwan et al., 2001; Hanai et al., 1996). Topoisomerase IV has also been described, a bacterial type II topoisomerase (Kato et al., 1990). More recently, topoisomerase V has been described, which is a prokaryotic counterpart to the eukaryotic topoisomerase I (Slesarev et al., 1994).
The Relationship between Perceived Organizational Justice and OCBs with Consider Moderating Role of Equity Sensitivity: Some Cultural Implications

Perceived organizational justice is an important factor for prediction of various aspects of OCBs. This research investigates the extent to which equity sensitivity moderates the relationship between perceived organizational justice and OCBs. It was hypothesized that distributive, procedural, informational and interpersonal justice are related to OCBs (helping behavior, civic virtue, and sportsmanship) and equity sensitivity has been moderate these relationships. Research sample group were 123 employees of a petrochemical company in Iran. The moderated hierarchical regression analysis indicated that equity sensitivity moderates the relationship between perceived distributive organizational justice with civic virtue and sportsmanship. That is, in entitled group (and no in equity sensitive or benevolent groups) distributive justice positively and significantly related to civic virtue and sportsmanship (P<0.05). Also results indicated that equity sensitivity moderates the relationship between perceived procedural organizational justice and sportsmanship. That is, in an equity sensitive group (and no in entitled or benevolent groups) procedural justice positively and significantly related to sportsmanship (P<0.05).
The Moderating Role of Staff Efficiency in the Relationship between Bank’s Specific Variables and Liquidity Risk in Islamic Banks of Gulf Cooperation Council (GCC) Countries

The efficiency of bank’s staff plays a crucial role in managing and mitigating the financial risks like liquidity risk. The aim of this paper is to propose a conceptual model/framework for investigating the moderating role of staff efficiency on the relationship between bank’s specific variables and liquidity risk in Islamic banks in Gulf Cooperation Council (GCC). GCC economies depend heavily on oil revenues which makes it subject to oil prices fluctuations. Therefore, liquidity in GCC banks, especially Islamic banks almost always suffers liquidity pressure. Thus, the issue of liquidity in this region has grown in importance in light of recent oil decline. Several attempts have been made to investigate the determinants of liquidity risk, yet the findings lack consistency. Most of the previous studies have ignored GCC region and have focused on other environments like credit risk but gave less attention to the moderating role of staff efficiency function in the Islamic banks with respect to liquidity risk. This paper offers a framework by adding a moderator of staff efficiency to the existing models of the bank’s specific determinants of liquidity risk with a particular attention to the GCC countries which are heavily dependent on oil revenues and always are subject to the impact of oil prices instabilities. Many stakeholders should benefit from the outcomes of this study. It should pave the way for bankers, regulators, investors and researchers to have a better understanding and insight about the factors that affect liquidity risk in the aforesaid banks.
A Comparison of Project Alliancing and Lean Construction

As the adoption of both alliancing and lean in the construction industry has started becoming more prevalent, knowledge of the alignment of Lean Construction with alliancing could be valuable to practitioners looking at adopting lean project delivery. This paper contributes to addressing this issue by providing insight into the relationship between the alliancing project delivery method and Lean Construction project delivery through the review of a literature review, interviews and a document study. A major driver of alliancing is to deliver value for money to the client, so it comes as a surprise that, to this date, alliancing has yet to fully capitalize on the Lean Construction operating system to drive the pursuit of maximum value. The inclusion of a lean operating system would require only minor changes to the existing structure of a standard project alliancing agreement. Alliancing could essentially remain the same, both structurally and commercially, while incorporating Lean Construction methods and tools into its operating system. In the right circumstances, this combination could be used to deliver greater value to the client.
Woody forest products utilization and rural area transformation in Eastern Uganda: a case of Nabitende Township, Iganga district

Exploitation of woody forest products on private land has superseded their regeneration hence unsustainable despite the many benefits accrued from the activity in eastern Uganda. A study of 253 households from Nabitende Township, a timber collecting centre with an agglomeration of wood processing workshops in Iganga district revealed that; the major woody forest products exploitation activities at Nabitende Township were furniture making (75%) and pit sawing/timber processing (59.3%); a correlation analysis of the perception of both wood processors and non-wood processors on the factors favouring wood works at the township showed that r=0.25 at 0.05 level of significance which was a slight relationship but the artisan skills was generally agreed as the major factor(85.8%); the most preferred timber species was Maesopsis eminii (86.2%) and Milicia excelca (86.2%) while the least were fruit trees, Mangifera indica (51.8%) and Artocapus heterophylus (59.7%);the woody forest products were sourced from the neighbourhood of the township such as Kaliro district, Buyende district, Namutumba district and Nawandala sub-county;Iganga town was the most significant market for wood products from Nabitende township at (χ 2 =1.7<9.21 at df=2) compared to other markets. This could be attributed to the place being a collecting centre in Eastern Uganda. Other very significant markets were Busia, Mbale, Kampala city, Kumi, Juba city, Malaba and Jinja town all at (χ 2 <9.21 at df=2); despite the statistically negative correlation interviews and observation agree on the fact that forest wood products exploitation has transformed the hither to rural environment. The researchers therefore recommended that both forest and environmental officers should sensitize the artisans on sustainable utilization of woody forest products especially discouraging wasteful machines; the local authorities to enforce the labour laws deterring child labour and early marriages to give room for education so as to sustain the transformation so far achieved.
Shadowing Ministers

In this article the authors study delegation problems within multiparty coalition governments. They argue that coalition parties can use the committee system to “shadow” the ministers of their partners; that is, they can appoint committee chairs from other governing parties, who will then be well placed to monitor and/or check the actions of the corresponding ministers. The authors analyze which ministers should be shadowed if governing parties seek to minimize the aggregate policy losses they suffer as the result of ministers pursuing their own parties’ interests rather than the coalition’s. Based on data from 19 mostly European parliamentary democracies, the authors find that the greater the policy disagreement between a minister’s party and its partners, the more likely the minister is to be shadowed.
Procedure for Maturation and Spawning of Imported shrimp Litopenaeus vannamei in Commercial Hatchery, South East Coast of India

The reproductive performance of the broodstock was assessed at each stage of the maturation and spawning process. Measures of maturation rate, spawning rate, fecundity, hatch rate and nauplii production rate were obtained. The reproductive performance was found for the imported Specific Pathogen Free (SPF) broodstock from Shrimp Improvement system (SIS), Florida, USA. The no.of spawning, eggs quantity, fertility, hatching rate and nauplii production were lowest in 1st to 3rd spawning when females were 7 months old and increased from 4th spawning rate onwards. As the size of females increased from 30 g to 52 g the mean number of eggs per spawning increased from 150,000 to 442,000. Although female body weight was increasingly larger through the study period and the larger females would be expected to produce more eggs per spawning and hatching. The hatching rate was increased from 3rd spawning onwards. The nauplii production rate (NPR), which is a function of egg production and hatching rate, showed a significant increasing from 48% to 96%. In 10th spawning all the activities were increased. This information can be used to select broodstock for hatchery production.
Determining the Variables That Affect the Reading Motivation of Educational Faculty Students.

Reading motivation has a significant contribution to acquire the necessary reading skills, and it has an indisputable effect on continuing to read. When the importance of the role model effect of school teachers in acquiring reading skills is considered, it is expected that reading motivation of the students will be high whose teachers also have a high reading motivation. Considering these issues, this study aimed to determine the variables that affect the reading motivation of students studying at the Faculty of Education. For this purpose, Adult Reading Motivation Scale (ARMS) developed by Schutte and Malouff, and adapted into Turkish by Yildiz et al. was used as the data collection tool. This scale was used for 285 students studying at five different departments in Sinop University, Faculty of Education, in Turkey. For data analysis, relational screening model was used. From the analysis, it was noticed that the variables, gender, profession of father, economic status, frequency of buying newspapers, frequency of buying magazines, frequency of reading in electronic environment, and the reasons for unwillingness to read were efficient upon reading motivations of students whereas the variables such as department, educational level of father, educational level of mother, and profession of mother were not efficient. Key words: Reading, reading motivation, reading interest.

Fibroblast growth factor 21 and its relationship with insulin sensitivity in first-degree relatives of patients with type 2 diabetes mellitus

Introduction: Fibroblast growth factor 21 (FGF 21) has been suggested as a predictor for the development of type 2 diabetes mellitus (T2DM). Material and methods: We aimed to determine FGF 21 levels in normoglycaemic (Group 1) and prediabetic (Group 2) first-degree relatives (FDR) of patients with T2DM in comparison with normoglycaemic subjects without a history of T2DM in their FDR (Group 3). Results: There was a significant difference between Group 1, 2, and 3 with respect to plasma FGF 21 concentrations (143.3 ± 93.8, 221.9 ± ± 171.7 and 121.2 ± 119.8 pg/mL, respectively, p = 0.01). FGF 21 levels were significantly increased in prediabetic FDR of patients with T2DM compared to normoglycaemic subjects without a history of T2DM in their FDR (p = 0.02). FGF 21 levels did not differ between normoglycaemic FDR of patients with T2DM and normoglycaemic subjects without a history of T2DM in their FDR (p > 0.05). In the whole group, FGF 21 correlated positively with age (r = 0.31, p = 0.003), BMI (r = 0.38, p < 0.001), systolic blood pressure (r = 0.38, p = 0.001), diastolic blood pressure (r = 0.26, p = 0.02), fasting blood glucose (r = 0.24, p = 0.02), HOMA-IR (r = 0.23, p = 0.03), AUC glucose (r = 0.35, p = 0.001), and AUC insulin (r = 0.32, p = 0.003) and negatively with HDL cholesterol (r = –0.24, p = 0.02) and Matsuda ISI (r = –0.33, p = 0.002). In the regression analysis, BMI was the most predictive factor for FGF 21 levels (b = 0.41, r2 = 0.17, p < 0.001). Conclusions: We showed that FGF 21 concentrations are increased in prediabetic FDR of patients with T2DM and that there is a significant association between FGF 21 and obesity and insulin sensitivity.

Configuration-like spaces and coincidences of maps on orbits

In this paper we study the spaces of $q$-tuples of points in a Euclidean space, without $k$-wise coincidences (configuration-like spaces). A transitive group action by permuting these points is considered, and some new upper bounds on the genus (in the sense of Krasnosel'skii--Schwarz and Clapp--Puppe) for this action are given. Some theorems of Cohen--Lusk type for coincidence points of continuous maps to Euclidean spaces are deduced.
Echinacea and anti-inflammatory cytokine responses: Results of a gene and protein array analysis

Preparations of Echinacea (Asteraceae) are frequently consumed for the control and prevention of rhinovirus-induced colds and other respiratory disorders. Since it is now generally believed that the symptoms of rhinovirus colds are due to the enhanced secretion of inflammatory chemokines and cytokines, we decided to analyze the effects of rhinovirus infection and Echinacea treatment [defined extracts of E. purpurea (L.) Moench] on cytokine/chemokine gene expression and protein secretion in a line of human tracheo- bronchial epithelial cells. Among the collection of more than 50 cytokines and chemokines present in the gene arrays, 12 showed significant induction of expression by the virus (> 2-fold), some of them by more than 5-fold. However, not all of these resulted in similar changes in the corresponding proteins, presumably as a consequence of post-transcriptional changes. A total of 16 cytokines, mostly chemokines, showed substantial protein increases, including several, such as the well known pro-inflammatory cytokines IL-6 and IL-8 (CXCL8), which were induced in the absence of additional transcription. These results support the concept that virus-induced multiple inflammatory cytokines are responsible for the cold symptoms. In most cases, one or both Echinacea preparations reversed the viral stimulation, thus providing a basis for the anti-inflammatory properties attributed to Echinacea.
LIvRE: A Video Extension to the LIRE Content-Based Image Retrieval System

This project explores the expansion of Lucene Image Retrieval Engine (LIRE), an open-source Content-Based Image Retrieval (CBIR) system, for video retrieval on large scale video datasets. The fast growth of the need to store huge amounts of video in servers requires efficient, scalable search and indexing engines capable to assist users in their management and retrieval. In our tool, queries are formulated by visual examples allowing users to find the videos and the moment of time when the query image is matched with. The video dataset used on this scenario comprise over 1,000 hours of different news broadcast channels. This thesis presents an extension and adaptation of Lire and its plugin for Solr, an open-source enterprise search platform from the Apache Lucene project, for video retrieval based on visual features, as well as a web-interface for users from different devices. The results are assessed from two perspectives: a quantitative and qualitative one. While the quantitative one follows the standard practices and metrics for video retrieval, the qualitative assessment has been based on an empirical social study using a semi-interactive web-interface. In particular, a thinking aloud test was applied to analyze if the user expectations and requirements were fulfilled.
EFFECT OF STRUCTURAL CHANGES ON ENZYMATIC HYDROLYSIS OF EUCALYPTUS, SWEET SORGHUM BAGASSE, AND SUGARCANE BAGASSE AFTER LIQUID HOT WATER PRETREATMENT

A woody (eucalyptus (Eu)) and two herbaceous materials (sweet sorghum bagasse (SSB) and sugarcane bagasse (SCB)) were used to evaluate the effect of liquid hot water (LHW) pretreatment on enzymatic hydrolysis of various lignocelluloses. The results showed that enzymatic hydrolysis efficiency of pretreated materials was SCB>SSB>Eu at 5% solids loading, while SSB>SCB>Eu was at 10% and 20% solids loadings. This indicated the enzymatic hydrolysis efficiency of SCB could be influenced by solids concentration. The differences in surface morphology, crystalline structure, and functional groups of pretreated samples were also examined by scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. SEM photographs and crystallinity indexes (CrI) showed that the structural compactness was Eu>SSB>SCB for both of untreated and treated materials. FTIR spectra showed that the conspicuousness of physicochemical changes was SCB>SSB>Eu. The differences in enzymatic hydrolysis efficiency of pretreated materials can be ascribed mainly to the structural differences.
