The reproductive performance of first-cross Border Leicester X Merino ewes was measured at two levels of nutrition and at two seasons of mating. The number of dry ewes was greater at a low than at a high level of nutrition, and was greater at a December mating than at a March mating. These effects were independent. The incidence of both twin ovulation and twin births was greater at a high than at a low level of nutrition, and was greater in March than in December. These effects showed significant interaction. Seasonal changes in twinning rates were more pronounced at a high than at a low level of nutrition, and level of nutrition affected twinning rate to a greater extent in March than in December.

We analyze a range of macrofinancial indicators to extract signals about cyclical systemic risk across 107 economies over 1995–2020. We construct composite indices of underlying liquidity, solvency and mispricing risks and analyze their patterns over the financial cycle. We find that liquidity and solvency risk indicators tend to be counter-cyclical, whereas mispricing risk ones are procyclical, and they all lead the credit cycle. Our results lend support to high-level accounts that risks were underestimated by stress indicators in the run-up to the 2008 global financial crisis. The policy implications of conflicting risk signals would depend on the phase of the credit cycle.

This study examined interior design and fashion merchandising students because they creatively solve everyday consumer problems and employers competitively screen graduates for their creative and collaborative abilities. Students in these fields not only have to fulfill course requirements, but they also must exhibit a high level of creativity and be able to work with others. To examine the influence stress may have on the creative process of problem-solving, students working alone were compared to students working in teams. From this central focus, the study explored three research questions (RQ). RQ1 asked if stress is more likely to occur when students work alone as opposed to working in teams. RQ 2 pertained to what parts of the design process are stressful when working on a team as well as what parts are stressful when working alone. RQ3 dealt with how students deal with stress when working alone, and how do they deal with it when working on a team. The research study employed a mixed methods approach involving an online 29 questions survey developed by the researcher that asked students to rank their perceptions using a five-point Likert scale. At the end of the online survey students answered one open-ended question that captured students’ perceptions of stress. The outcomes indicated that individuals working alone and in teams had specific stress indicators at different points throughout the problem-solving assignments. Additionally, the study showed the value of social connectivity and freedom to select team members.

One of the most promising areas for the development of the domestic economy is the agricultural sector which is characterized by a high level of volatility due to a wide range of business risks including weather and seasonal changes. There are significant economic imbalances despite the active processes of automation of the agricultural sector as well as the desire of farmers to reduce the cost of production while simultaneously improving its quality. And it’s largely due to imperfect approaches to price formation. One of these problematic areas is the sphere of cargo transportation of agricultural products. Now the usual ways of supporting entrepreneurs in the form of preferential loans, special tax regimes, and aid grants are no longer fully able to create optimal conditions for agricultural producers. The reason of this is the complex, multi-faceted nature of production and financial and economic relations in the agricultural sector. Above-listed tools are able to harmonize the sphere of agriculture as an economic system, however, a number of issues require the development of effective organizational and economic measures in a rather tight range. So, it is advisable to review the pricing conditions for cargo transportation of agricultural products taking into account both the weather conditions and the factor of seasonality. The authors give reasons for the need to introduce a flexible approach to the application of trade surcharges (tariff schedule) in this area. The rationale for the feasibility of correcting prices for carriers’ services taking into account these factors is presented since the proposed measures reduce the surface damage of agricultural products during transportation. It leads to a longer period of sell-by-date and, that is why, obtaining additional income which more than compensates of the transportation costs increasing.

The newly formed leaves of both <i>Vaccinium</i> species show in June and July the lowest pH values, 3.4-3.7, which gradually increase up to 4.6 in November. The bi- and triennial leaves of <i>Vaccinium vitis-idaea</i> are less acid and show much morę limited seasonal decrease of acidity. The buffer capacity against acid of the current year leaves ,of the two species shows in summer a high level of values (a constant one for <i>Vaccinium myrtillus</i>), It decreases in autumn to achieve that of bi- and triennial leaves of <i>Vaccinium vitis-idaea</i>. The buffer capacity values are influenced to a limited extent by the increase in air-pollution, much smaller than that noticed for Pinus silvestris co-existing with <i>Vaccinium</i> in the same ecosystems.

A multisubunit RNA polymerase enzyme is ultimately responsible for transcription initiation and elongation of RNA, but recognition of the proper start site by the enzyme is regulated by general, temporal and gene-specific trans-factors interacting at promoter and enhancer DNA sequences. To understand the molecular mechanisms which precisely regulate the transcription initiation event, it is crucial to elucidate the structure of the transcription factor/DNA complexes involved. Electron spectroscopic imaging (ESI) provides the opportunity to visualize individual DNA molecules. Enhancement of DNA contrast with ESI is accomplished by imaging with electrons that have interacted with inner shell electrons of phosphorus in the DNA backbone. Phosphorus detection at this intermediately high level of resolution (≈lnm) permits selective imaging of the DNA, to determine whether the protein factors compact, bend or wrap the DNA. Simultaneously, mass analysis and phosphorus content can be measured quantitatively, using adjacent DNA or tobacco mosaic virus (TMV) as mass and phosphorus standards. These two parameters provide stoichiometric information relating the ratios of protein:DNA content.

The forte of the Scanning transmission Electron Microscope (STEM) is high resolution imaging with high contrast on thin specimens, as demonstrated by visualization of single heavy atoms. of equal importance for biology is the efficient utilization of all available signals, permitting low dose imaging of unstained single molecules such as DNA.Our work at Brookhaven has concentrated on: 1) design and construction of instruments optimized for a narrow range of biological applications and 2) use of such instruments in a very active user/collaborator program. Therefore our program is highly interactive with a strong emphasis on producing results which are interpretable with a high level of confidence.The major challenge we face at the moment is specimen preparation. The resolution of the STEM is better than 2.5 A, but measurements of resolution vs. dose level off at a resolution of 20 A at a dose of 10 el/A2 on a well-behaved biological specimen such as TMV (tobacco mosaic virus). To track down this problem we are examining all aspects of specimen preparation: purification of biological material, deposition on the thin film substrate, washing, fast freezing and freeze drying. As we attempt to improve our equipment/technique, we use image analysis of TMV internal controls included in all STEM samples as a monitor sensitive enough to detect even a few percent improvement. For delicate specimens, carbon films can be very harsh-leading to disruption of the sample. Therefore we are developing conducting polymer films as alternative substrates, as described elsewhere in these Proceedings. For specimen preparation studies, we have identified (from our user/collaborator program ) a variety of “canary” specimens, each uniquely sensitive to one particular aspect of sample preparation, so we can attempt to separate the variables involved.

Purpose A questionnaire survey was conducted to collect information from clinical audiologists about rehabilitation options for adult patients who report significant auditory difficulties despite having normal or near-normal hearing sensitivity. This work aimed to provide more information about what audiologists are currently doing in the clinic to manage auditory difficulties in this patient population and their views on the efficacy of recommended rehabilitation methods. Method A questionnaire survey containing multiple-choice and open-ended questions was developed and disseminated online. Invitations to participate were delivered via e-mail listservs and through business cards provided at annual audiology conferences. All responses were anonymous at the time of data collection. Results Responses were collected from 209 participants. The majority of participants reported seeing at least one normal-hearing patient per month who reported significant communication difficulties. However, few respondents indicated that their location had specific protocols for the treatment of these patients. Counseling was reported as the most frequent rehabilitation method, but results revealed that audiologists across various work settings are also successfully starting to fit patients with mild-gain hearing aids. Responses indicated that patient compliance with computer-based auditory training methods was regarded as low, with patients generally preferring device-based rehabilitation options. Conclusions Results from this questionnaire survey strongly suggest that audiologists frequently see normal-hearing patients who report auditory difficulties, but that few clinicians are equipped with established protocols for diagnosis and management. While many feel that mild-gain hearing aids provide considerable benefit for these patients, very little research has been conducted to date to support the use of hearing aids or other rehabilitation options for this unique patient population. This study reveals the critical need for additional research to establish evidence-based practice guidelines that will empower clinicians to provide a high level of clinical care and effective rehabilitation strategies to these patients.
