Use of condensate drain to pre-cool the inlet air to the condensers: A technique to improve the performance of split air-conditioning units

In hot ambient conditions, split air-conditioning (AC) systems experience a drop in their coefficient of performance and an increase in power consumption due to the direct relationship between the condensation temperature of the unit and the prevailing ambient temperature. In this work, the enhancement in the COP and the reduction in power consumption for a split AC unit are evaluated when a direct water spray evaporative cooling system is used. The study focuses on minimizing the amount of water needed to cool the condenser by utilizing the wasted water from the condensate drain, synchronizing the water injection with ON–OFF compressor operation, and determining the optimal hourly periods for the injection system to achieve a reduction in energy consumption. The objectives of this work are threefold. The first objective is to conduct experiments inside an environmental chamber to determine the effectiveness of the evaporative cooling system at different ambient conditions and to derive correlations that predict the outlet air conditions and the water consumption. The second objective is to develop an integrated mathematical model to simulate the performance of the evaporatively cooled split AC system in a controlled space under certain operational conditions (using steady-state performance data supplied by the manufacturer and taking into account the transient effect during the ON–OFF compressor cycling) and to experimentally validate this model. The third and final objective is to evaluate the model under “real environment conditions” for a case study where the thermal conditions and energy demand of a typical office space in Beirut during three months (June, August, and October) are investigated and where the “sufficiency” of drain water is the limiting factor. The simulation results have shown that the drain water would be sufficient in October only, resulting in 5.3% energy saving throughout the whole day. On the other hand, the synchronized spray of water is found to last for six operating hours in a June day and eight hours in August; this results in a total daily reduction in the consumed energy of 5% in June and 4.5% in August.
Subcutaneous Trastuzumab with Pertuzumab and Docetaxel in HER2-Positive Metastatic Breast Cancer: Final Analysis of MetaPHER, A Phase 3b Single-Arm Safety Study

BACKGROUND Intravenous trastuzumab, pertuzumab, and docetaxel is first-line standard of care for patients with HER2-positive metastatic breast cancer. Subcutaneous trastuzumab plus intravenous pertuzumab and chemotherapy has shown similar safety and tolerability to intravenous trastuzumab in patients with HER2-positive early and metastatic breast cancer; however, in the metastatic setting, this has yet to be shown globally.METHODS In this open-label, single-arm, multicenter phase 3b study, eligible patients were ≥18 years old with histologically/cytologically confirmed previously untreated HER2-positive metastatic breast cancer. All patients received ≥1 dose of subcutaneous trastuzumab (fixed-dose 600 mg) plus intravenous pertuzumab (loading dose: 840 mg/kg; maintenance dose: 420 mg/kg) and docetaxel (≥6 cycles; initial dose 75 mg/m2) every 3 weeks. The primary objective was safety and tolerability; secondary objectives included efficacy.RESULTS At clinical cutoff, 276 patients had completed the study; median duration of follow-up was 27 months. The most common any-grade adverse events were diarrhea, alopecia, and asthenia. The most common grade ≥3 adverse events were neutropenia, febrile neutropenia, and hypertension. There were no cardiac deaths and mean left ventricular ejection fraction was stable over time. Median investigator-assessed progression-free survival was 18.7 months; objective response rate was 75.6%. CONCLUSIONS Efficacy/safety results of subcutaneous trastuzumab plus intravenous pertuzumab and docetaxel in metastatic breast cancer are consistent with historical evidence of intravenous trastuzumab. These findings further support the body of evidence indicating that subcutaneous administration does not affect the safety and efficacy profile of trastuzumab in HER2-positive breast cancer.

The results were compared with data for the 17 percent thick low speed airfoil (LS(1)-0417) and the 13 percent thick medium speed airfoil (MS(1)-0313). Theoretical predictions of the drag rise characteristics of this airfoil are also provided. The tests were conducted in the Langley low turbulence pressure tunnel over a Mach number range from 0.10 to 0.32, a chord Reynolds number range from 2 million to 12 million, and an angle of attack range from about -8 to 20 deg.
Advanced gynecological cancer: Quality of life one year after diagnosis

Objective Gynaecological cancer treatment impacts women’s physical and psychological health. Our objective was to examine quality of life (QoL) in women with advanced gynaecological cancer at diagnosis and one year later, and to identify sociodemographic and clinical characteristics associated with QoL. Methods Women with endometrial, ovarian or cervical cancer treated in Uppsala, Sweden 2012–2019 were included. FIGO stage ≥II was considered advanced gynaecological cancer, whereas women in FIGO stage I were used as a control group. QoL was assessed with SF-36. We obtained information on sociodemographic and clinical characteristics from medical records and health questionnaires. Differences in QoL domains were tested with t-tests, a mixed model ANOVA and multiple linear regression analyses. Results The study population (n = 372) included 150 (40.3%) women with advanced gynaecological cancer. At diagnosis, women with advanced cancer reported lower physical (71.6 vs 81.8 (mean) p<0.05) and role functioning/physical scores (62.6 vs 77.2 (mean) p<0.05) than women in FIGO stage I. One year later, women with advanced cancer reported higher scores in the mental health domain (78.3 vs 73.2 (mean) p<0.05) than women in FIGO stage I. However, no difference was found in the QoL scores of women with advanced disease one year after diagnoses when stratified by diagnosis. Women with a history of psychiatric illness and higher BMI reported poorer physical and mental QoL at follow-up, while advanced stage, level of education and smoking were not associated with QoL. Conclusion Women with advanced gynaecological cancer have equally good QoL one year after diagnosis as women with limited disease. Women with previous psychiatric illness and high BMI, are at risk of impaired physical and mental health.
Design of an efficient, low weight battery electric vehicle based on a VW Lupo 3L

th century aside. At the beginning of the 1970’s with the oil crisis and increasing worries about air pollution the electric car gained interest again. At the Eindhoven University of Technology a project was executed in which a VW Golf was converted to a battery electric vehicle, figure 1 gives an impression. Though interesting research was done with this vehicle, in particular regarding the possible efficiency increase using various gearbox configurations, it was also clear that the converted vehicle was no match for the internal combustion engine (ICE) cars of those days [1]. Figure 1: The TU/e battery electric VW Golf 1 as developed in the years 1980 to 1983.
Comprehensive investigation of alternating and rotational losses in non-oriented steel sheets

Magnetic losses have been investigated as a function of frequency in non-oriented steel sheets under alternating and rotational flux. Accurate measurements could be performed over a large induction range, extending up to the approach to saturation, by combining the fieldmetric and thermometric loss measuring methods. It is verified that for both rotational and alternating losses one can apply the concept of loss separation, where the hysteresis, excess, and classical loss components are in a frequency independent relationship.

Performance Analysis of Battery Based Stand-Alone Solar Home Systems in Malawi

Battery based standalone SHS (solar home systems) are installed in Malawi to expedite rural electrification. A study was conducted to analyze the performance of SHS in low and high insolation areas of Malawi. It is found that if the system is designed in accordance to procedures stipulated in Malawi standards, then it is capable of operating annually with mean performance ratio of 0.68, PV array production factor of 0.88 and system efficiency of 78% indicating a good system performance. The system is more reliable in high insulation areas (loss of load probability = 0.09) and when the battery charging is given priority during daytime, the overall system's reliability is improved by 40%. However, if the system is under-designed its performance ratio is reduced considerably and the system becomes less reliable. In overall, SHS in Malawi perform reliably if the system is well designed and maintained.
Rapid manufacturing in the spare parts supply chain: Alternative approaches to capacity deployment

Purpose – The purpose of this paper is to describe and evaluate the potential approaches to introduce rapid manufacturing (RM) in the spare parts supply chain.Design/methodology/approach – Alternative conceptual designs for deploying RM technology in the spare parts supply chain were proposed. The potential benefits are illustrated for the aircraft industry. The general feasibility was discussed based on literature.Findings – The potential supply chain benefits in terms of simultaneously improved service and reduced inventory makes the distributed deployment of RM very interesting for spare parts supply. However, considering the trade‐offs affecting deployment it is proposed that most feasible is centralized deployment by original equipment manufacturers (OEMs), or deployment close to the point of use by generalist service providers of RM.Research limitations/implications – The limited part range that is currently possible to produce using the technology means that a RM‐based service supply chain is feasi.
Course-Specific Corpora in the Classroom: A News Media English Class in Taiwan

This study explores the feasibility of constructing a learning tool with the benefits of data-driven learning from a course-specific corpus and integrating it into a news media English class. Given the popularity of news media English classes in some Asian countries and the call in recent years for instructors to construct smaller and more specialized corpora to meet specific instructional objectives, an on-line system for assisting teaching and reading of English news was developed and used in a university-level news media English class in Taiwan. A lesson incorporating the system was designed and implemented. The lesson aimed at teaching the discourse features of news stories and improving English in general. After the lesson, students’ responses to using the system were obtained by a questionnaire survey. Results of the questionnaire survey indicated an overall positive response to incorporating the learning tool into a news media English class along with suggestions for system design. The paper concludes with implications for future use of the system and possible ways to improve the design of systems for similar purposes.
Design optimization of truss structures using cuckoo search algorithm

A new metaheuristic optimization algorithm is developed to solve truss optimization problems. The new algorithm, called cuckoo search (CS), is examined by solving five truss design optimization problems with increasing numbers of design variables and complexity in constraints. The performance of the CS algorithm is further compared with various classical and advanced algorithms, selected from a wide range of the state‐of‐the‐art algorithms in the area. The results identify that the final solutions obtained by the CS are superior compared with the best solutions obtained by the other algorithms. Finally, the unique search features used in the CS and the implications for future researches are discussed in detail. Copyright © 2012 John Wiley & Sons, Ltd.
Characterization of Lactic Acid Bacteria Isolated from the Gastrointestinal Tract of Ethiopian Rhode Island Red Chicken and their Potential Use as Probiotics

Background Chicken productivity and survival is affected by environmental stress and incidences of different diseases. After the ban of antibiotics growth promoters by different countries, the use of probiotics feed additives is mentioned as one alternative to antibiotics. The objective of this study was to isolate and identify potential probiotic lactic acid bacteria strains from the digestive tract content of Rhode Island Red chicken. Results The study was conducted in Gondar town of Amhara region, North West Ethiopia from November, 2018 to March, 2019. From the gastro intestinal content of 5 chicken 190 isolates were randomly selected. The isolates were identified and screened by their biochemical, morphological and 16S rRNA gene sequence. The in vitro probiotic potential of isolates was characterized by various tests. From 190 isolates 73 were found as gram positive, catalase negative and were able to grow at pH4. The bacteria were either rod (83.6%) or round (16.4%) shaped. Ten isolates were then randomly selected for further in vitro probiotic characterization due to higher cell surface hydrophobicity, good survival at pH2 and survival at 0.1% bile salt. From the 10 isolates 6 were able to survive at pH1 for 3hrs incubation. Five isolates (IS1, IS2, IS5, IS7 and IS8) were resistance to ampicillin, chloramphenicol, ciprofloxacin and erythromycin antibiotics. All the ten isolates showed antagonistic activity against Escherichia coli, Staphylococcus aureus, Salmonella typhimurium, Staphylococcus intermedius and Salmonella enteritidis. The optimum temperature for all ten isolates was 450C and all the isolates were able to grow at 0.69 mol/L of NaCl, and were able to ferment galactose, glucose, fructose, mannitol, sorbitol and sucrose. Using phylogenetic analysis of 16SrRNA gene sequence; IS3 was identified as Lactobacillus salivarius while IS4, IS6 and IS7 were identified as Lactobacillus reuteri. Conclusion The study concludes that the 10 selected isolates can be able to survive the stress conditions of gastrointestinal tract and can thus be considered as potential probiotics candidates for chickens.
Effect of form of hay and carcass quality on the economics of concentrate: hay substitution in cattle feedlot diets.

A maximum profit linear programming feedlot model is presented to determine if diet combinations of moderate amounts of hay and grain are economically optimal when time (length of the feeding period), form of hay (long versus cubed alfalfa), and carcass quality are considered. While the experiment did not include concentrate-to-hay ratios as high as commercial feedlot use, the results show that highest concentrate diets are economical in all stages of the finishing program, except that when time and carcass grade effects are considered and hay-to-concentrate price ratios are at historical lows, a switch is made for the last 90 kg of grain to diets somewhat above 50% hay.
Staff Prediction Analysis : Effort Estimation In System Test

This master thesis is made in 2001 at Blekinge Institute of Technology and Symbian, which is a software company in Ronneby, Sweden. The purpose of the thesis is to find a suitable prediction and estimation model for the test effort. To do this, we have studied the State of the Art in cost/effort estimation and fault prediction. The conclusion of this thesis is that it is hard to make a general proposal, which is applicable for all organisations. For Symbian we have proposed a model based on use and test cases to predict the test effort.
The interactive support of cognitive reserve and semantic knowledge in proper name retrieval

ABSTRACT Cognitive reserve (CR) refers to acquired experience that modulates resistance to physiological aging or brain damage. A relatively neglected issue is whether or not CR affects cognitive abilities equally. One relevant component of CR seems to be the richness of connections in semantic knowledge. We examined, in N = 66 healthy older adults, the potential influence of CR and semantic knowledge on the ability to retrieve proper names and common nouns. These two name categories have different semantic organisations, whereby proper names are characterised by a weaker semantic link to the information they refer to. Controlling for age, CR and semantic knowledge were linearly and positively associated with common noun retrieval. On the other hand, CR assisted proper name retrieval in older adults with a weaker semantic profile, while semantic knowledge assisted proper name retrieval in older adults with lower CR. This study contributes to define the cognitive underpinnings of CR.
The Relativistic and the Hidden Momentum of Minkowski and Abraham in Relativistic Energy Wave

An analysis of the consistency of the Abraham and Minkowski momenta in the determination of the photon trajectory was carried out considering a new principle of conservation of the photon's mechanical energy, in which the photon conserves translational energy in orbital angular momentum when transiting between two media, introducing the relativistic energy wave (REW). The confrontation between REW and the recent theory of space-time waves (ST) was considered, pondering your differences. Throughout this study it was possible to verify that the Abraham momentum appears a relativistic photon ignition device in the transition between two media, acting as the hidden momentum of the Minkowski’s relativistic momentum. The wavy behavior in the matter is relativistic, and the relativistic trajectory appears with delays and advances, with points of synchronization between source-observer. The classical or relativistic trajectories are determined as a function of the angle of incidence and the relative refractive index, by one of two distinct non-additive torques, the classic by Abraham or the relativistic by Minkowski. It was found that the same analysis conducted under the principle of conservation of the mechanical energy of the photon can be treated by an new Doppler, Relativistic Apparent, that can be confused with other Dopplers in the treatment of redshift from distant sources. It was found that the conservation of energy in Orbital Angular Momentum (OAM), in the interaction with matter, explains that the synchronization instants are found in the inversion of the OAM, where the advances and delays of REW occur under negligible variations of the OAM, however, opposites.
Effects of conspecific lures, call playbacks, and moonlight on the capture rate of Xenopus laevis, a major invasive amphibian

Given the status of the African clawed frog Xenopus laevis as a global amphibian invader, and the potential spread of its invasive populations in Europe and other continents, it is essential to identify the environmental factors and methods that maximize the trapping output of control actions. Cost-effective methods should maximize the number of trapped individuals, and preferably the number of females. We tested five types of attractants in traps, split into two categories: playbacks and conspecific lures, and compared their efficiency in terms of number of trapped individuals (total, females, and males) against the control method currently in use in France (use of food bait). We also estimated the influence of moonlight, an environmental factor known to affect amphibian activity. Playback methods did not increase the capture probability for either sex. In contrast, using a female as a lure allowed us to trap both more individuals (224% compared to the control), more females (186%) and more males (190%), whereas using a male only allowed us to trap more males (167%). These effects were stronger under low moonlight intensity, and at the end of the breeding season. Using female lures appeared to be the best method, both due to a higher number of trapped individuals and a higher number of trapped females. Our study also emphasizes the need for considering the influence of the lunar cycle when planning fieldwork to optimize the cost-efficiency of control actions. We recommend to preferentially set traps under low moonlight intensities.
