Published: May 2019

Abstract
Tofu industries produce by product of whey which is still rich in organic content. Tofu industry of using soy bean of 1400 – 1600 kg/day produces 25 m3 of wastewater per day of 6321 mg COD/liter. This high content of COD and volume of wastewater instead of potential pollution could be transformed into biogas and used by local communities for domestic purposes like alternative energy for cooking. This study is aimed to assess the possibility of using wastewater from tofu industry by local communities for cooking. Asri Tofu Industry with such typical production of wastewater was assessed to treat its wastewater while the by-product of biogas would be used by local communities for cooking. About 38 m3 biogas per day could be produced per day and can be used by at least 117 houses in the nearby factories not far from 300 m from the factory. The use of biogas would reduce local community expenses to buy LPG and woods for cooking.

Published: May 2019

Abstract
The adaptation level among maize genotypes under drought stress is strongly affected by morphology and physiology aspects. To assess the adaptation level of maize hybrids to drought weight, an experiment was conducted in the dry season of 2016 (June to September) at Maros Experimental Station. A total of 70 maize hybrids candidates were evaluated under drought stress at generative (flowering stage) until physiological maturity. The results indicated that leaf rolling scores were negatively correlated with grain yield under drought stress conditions. The hybrid 26/B11209 and P 31 that experienced early leaf moving and a higher leaf rolling score ranged from 4.3, and 3.9 had grain yield of only 1.3 t/ha and 1.2 t/ha respectively, lower compared to the hybrid 34/Mal 03 and Bisi 18 that experienced a delayed leaf rolling and lower leaf rolling score (<2.5) with yields of 4.3 t/ha and 3.9 t/ha respectively. The hybrids 34/Mal 03 and Bisi18 had mechanisms to reduce the area of leaves affected by radiation and maintain relatively higher leaf moisture content compared to hybrids 26 / B11209 and P 31. Leaf relative moisture content of hybrid maize 34/Mal 03 and Bisi 18 were higher viz., 79.9% and 78.7% respectively and lower leaf temperatures (39.4-39.8 °C) as compared to hybrids 26 / B11209 and P 31. The effective score assessment time of leaf rolling of the hybrid genotypes was when the whole hybrid genotypes experienced leaf rolling with ±50% genotype had leaf rolling scored 2 and ±50% of other genotypes scored 3.

Authors: Rijal S 
Published: May 2019

Abstract
Deforestation assessments based on the rate number and extent of the deforestation area. This assessment of deforestation has the potential to provide wrong information about the condition of a region’s forests. High deforestation rates are known as the area with high forest destruction. Otherwise, the area with low rates of deforestation are known as the areas with better forest conditions. The rate of zero deforestation was known as a non-deforestation area. In fact, a low rate deforestation in a region are not necessarily mean having a better forest. This study was aimed to determine the typology of deforestation in Riau Province. The research method was done by analyzing land cover data with Geographic Information System. Deforestation typology assessments were conducted by using the variables of the proportion of the initial forest area of a regency, the incidence of deforestation and the rate of deforestation. The deforestation typology of the regency level in Riau Province has shown in 5 deforestation profiles. The highest typology is Large-Lately-Low Deforestation (5 regencies), which is indicating that the incidence of deforestation in Riau Province occurred in large forest areas, mostly occurred in the second period of observation with high rate. Riau Province is the province with the highest number of forest area in Sumatra (1990) and the highest rate of deforestation (68.18%). Deforestation in Riau Province from 1990 to 2013 is the deforestation typology of Early deforestation.

The model needs to be tested and further studied regarding the potential economic efficiency created and the value of economic benefits received by each stakeholder on the implementation of the model.
Internal and External Implementation Strategy of Collaboration Management Model in Hasanuddin University Educational Forest
Authors: Yusran  , Sabar A 
Published: May 2019

Abstract
The management of educational forest with multiple stakeholder approaches is expected to contribute to the success of educational forest management. The results of previous studies recommended the need to strengthen multiple parties to build a collaborative management model by considering aspects of needs and clarifying the role of stakeholders, so that common perceptions were developed in managing the area and anticipating overlapping in carrying out their respective roles. This study aims to analyze the internal and external strategies for implementing the collaboration management model in the Hasanuddin University Educational Forest area. The methodological approach using descriptive policy analysis, internal and external strategy analysis (review of IFAS-EFAS) were chosen to achieve the expected goals. The results of IFAS-EFAS strategy analysis proposed four main strategies. The first one is a strategy which maximizes the power to seize opportunities (SO), namely a plan for empowering the surrounding forest community through the Social Forestry scheme in a strategic plan and utilizing the human resources to promote and jointly developing eco-tourism potential. The second one is a strategy that utilizes maximum use of power to anticipate or deal with threats and try to make threats as opportunities (ST), namely to make experts and other human resources as mediators or facilitators to relevant parties so that mutual understanding can be developed regarding management objectives. The third one is a strategy that minimizes weaknesses to seize opportunities (WO), namely improvements in the funding area through fundraising to improve the quality of educational forest management, including the improvement of supporting facilities and infrastructure through the concept of partnership with the community, and massive promotion of eco-tourism potential. The fourth one is a strategy that minimizes weaknesses to avoid threats well (WT), namely managing budget that is right on target, accountable, and transparent, to avoid negative stigma from the community.
Identification of the Minimum Number of Measurements Required for Thermal Comfort Assessment in Large Workplaces
Authors: Lenzuni Paolo , Tura Pierangelo , Cervino Pierfrancesco 
Published: May 2019

Abstract
Optimization of resources is the key to improve our ability to perform multiple tasks with limited time and money. In the context of thermal comfort assessment, optimization becomes important in large rooms where tens of individuals perform similar tasks. This work focuses on the identification of the minimum number of measurement points that allows an accurate description of the thermal environment. Accuracy of description is assumed if no significant loss of information is associated to the transition from the ‘primary’ thermal map based on all available measurement points to a ‘secondary’ thermal map based on a reduced set of measurement points. The concept of ‘no significant loss’ is quantified by requiring that the difference in PMV (Predicted Mean Vote) between the two maps is kept <0.1 in the vast majority (95%) of points. PMV is a standardized synthetic index that is used worldwide for quantifying thermal comfort (ISO 7730, 2005) taking into account both environmental (thermo-hygrometric) and personal (activity, clothing) quantities.
We show that the uncertainty induced by the degraded resolution of the thermal map has a limited impact on the overall uncertainty on PMV. Application of the method to a few test environments shows that the room size perpendicular to the main window and the windows orientation play the largest role in determining spatial inhomogeneity in thermal maps. A minor concurring factor is the room area.
Alternative reproductive tactics shape within-species variation in behavioral syndromes
Authors: Han Chang S , Jablonski Piotr G 
Published: May 2019

AbstractMultiple behaviors can correlate with each other at the individual level (behavioral syndrome), and behavioral syndromes can vary in their direction between populations within a species. Within-species variation in behavioral syndromes is predicted to be associated with alternative reproductive tactics (ARTs), which evolve under different selection regimes. Here, we tested this using a water strider species, Gerris gracilicornis, in which males employ 2 ARTs that are fixed for life: signaling males (producing courtship ripples) versus nonsignaling males (producing no courtship ripples). We measured multiple behaviors in males with both of these ARTs and compared behavioral syndromes between them. Our results showed that signaling males were more active and attempted to mate more frequently than nonsignaling males. This shaped an overall behavioral syndrome between activities in mating and nonmating contexts when we pooled both ARTs. In addition, the behavioral syndromes between cautiousness and mating activity differed significantly between ARTs. In signaling males, the syndrome was significantly negative: signaling males more eager to mate tended to leave their refuges more rapidly. However, mating activity and cautiousness were not correlated in nonsignaling males. This might be because active males, in the context of predation risk and mating, were favored during the evolution and maintenance of the unique intimidating courtship tactic of G. gracilicornis males. Thus, our findings suggest that ARTs facilitate behavioral divergence and also contribute to the evolution of tactic-specific behavioral syndromes. We also show that research on ARTs and behavioral syndromes can be harmonized to study behavioral variation.
Eggshell coloration indicates female condition during egg-laying: a field experiment in blue tits

Published: May 2019

AbstractSeveral selection pressures may explain the evolution of avian eggshell coloration patterns. In cavity-nesting species, there are two main non-exclusive hypotheses. The sexually selected eggshell colour hypothesis proposes that eggshell coloration is a sexually selected signal of female and offspring quality used by males that influences paternal care or future re-mating decisions. The structural function hypothesis proposes that pigments help strengthen the eggshell and are present at higher levels and at the blunt end of the egg when females face calcium shortages. We tested whether eggshell coloration (brown spots on a white ground colour) in blue tits (Cyanistes caeruleus) could reliably indicate female condition at laying by forcing females to produce two consecutive clutches, thus increasing their reproductive costs. Three measures of eggshell coloration – the area covered by spots as well as white ground UV-chroma and brightness – changed between clutches; the fourth measure, spot distribution, did not. The changes were more dramatic in young and lower-quality females. All the measures varied with female quality (i.e. body condition and/or laying date). Overall, higher-quality females produced more colourful (larger, more concentrated spotted surface area; higher UV-chroma) and less bright (i.e. putatively more pigmented) eggshells, a result that is generally in line with past research. We found a clear empirical link between eggshell coloration and female condition in blue tits, an important step in determining whether eggshell coloration is a sexual signal, but which does not exclude a potential concomitant structural function.
The cost of fidelity: foraging oligolectic bees gather huge amounts of pollen in a highly specialized cactus–pollinator association

Published: May 2019

Abstract
Plant–pollinator interactions vary along a specialization–generalization continuum. Advances in understanding the evolutionary and ecological consequences of different degrees of specialization depend on precise data on plant–pollinator interdependency. We studied the association of Parodia neohorstii (Cactaceae) and its bee pollinators focusing on pollinator foraging behaviour, flower functioning, female and male reproductive success, and pollen fate. Parodia neohorstii showed synchronized flower opening and pollen presentation but discontinuous blooming. The apparently generalized flowers partition pollen through thigmonastic stamen movements that function as a mechanical filter against generalist bees by restricting access to the major pollen reservoir to bees that show flower handling ‘know-how’, thereby favouring the oligolectic bee Arhysosage cactorum. This pollinator adjusted its pollen foraging to flower opening, removed pollen hurriedly, and promoted maximal fruit and seed set, which was minimal in its absence. Estimates of pollen fate revealed that a huge amount of pollen flows to specialized pollinators (86.5%), and only 0.9% reaches conspecific stigmas. The specialized interaction between P. neohorstii and Arhysosage cactorum, both threatened species, is efficient but fragile. Any environmental modification that causes a mismatch between the partners is likely to result in reproductive failure.

Published: May 2019

AbstractOmadacycline is a semisynthetic tetracycline antibiotic. Phase III clinical trial results have shown that omadacycline has an acceptable safety profile in the treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia. Similar to most tetracyclines, transient nausea and vomiting and low-magnitude increases in liver aminotransferases were the most frequent treatment-emergent adverse events in phase III studies but were not treatment limiting. Package insert warnings and precautions for omadacycline include tooth discoloration; enamel hypoplasia; inhibition of bone growth following use in late pregnancy, infancy, or childhood up to 8 years of age; an imbalance in mortality (2%, compared with 1% in moxifloxacin-treated patients) was observed in the phase III study in patients with community-acquired bacterial pneumonia. Omadacycline has no effect on the QT interval, and its affinity for muscarinic M2 receptors resulted in transient heart rate increases following dosing.
